1N4148WS Diodes - Rectifiers - Single от onsemi

Specifies how the component is attached to the PCB, such as through-hole or surface mount. This affects assembly processes, thermal performance, and mechanical strength. Buyers should verify compatibility with their manufacturing capabilities and design requirements.

Maximum power the component can safely dissipate as heat without exceeding its thermal limits. Compare this rating with your application's expected power loss to ensure reliable operation. Always verify against the datasheet's derating curves and ambient temperature conditions.

Export Control Classification Number assigned by the U.S. government. Determines whether the component requires an export license. Essential for international trade compliance. Verify the ECCN with the manufacturer or supplier before shipping to avoid legal issues.

Indicates the physical package type as designated by the component manufacturer, such as SOIC, QFN, or BGA. This affects PCB footprint, thermal performance, and assembly processes. Confirm compatibility with your board layout and soldering requirements before design finalization.

Specifies whether the component or signal has a defined positive and negative orientation, such as for diodes, electrolytic capacitors, or connectors. Incorrect polarity can cause failure or unsafe operation. Always check the datasheet and board markings before installation.

Physical package or case type of the component, defining its dimensions, mounting style, and thermal characteristics. Common types include SMD, through-hole, BGA, and QFN. Choose the package that fits your PCB layout and assembly process. Verify the exact package code in the datasheet for footprint compatibility.

Indicates the product series or family, grouping components with similar design and specifications. Helps identify compatible parts and compare within a product line. Verify the series against the datasheet to ensure correct application.

Unique alphanumeric identifier assigned by the original manufacturer to specify a particular component version. Use this number to cross-reference datasheets, verify exact specifications, and ensure compatibility with your design. Always confirm it matches the part you intend to order.

Identifies the company that designed and produced the component. Buyers often filter by manufacturer to ensure brand reliability, quality standards, and supply chain consistency. Verify the manufacturer against the datasheet and official packaging to avoid counterfeit parts.

Specifies the internal circuit topology or arrangement of the component, such as single, dual, or bridge configuration. This attribute helps engineers select the right part for their circuit design. Always verify the exact configuration against the datasheet to ensure compatibility with your application.

Select the diode classification such as Schottky, Zener, or standard rectifier. This defines the device's electrical behavior and typical applications. Verify the exact type against the datasheet to ensure it meets your circuit requirements for voltage, current, and switching speed.

Time for a diode to transition from conducting to blocking state. Critical for switching losses in power circuits. Compare values when designing high-frequency converters or rectifiers. Verify against datasheet under specified test conditions.

Indicates the junction capacitance of the diode, affecting high-frequency performance and switching speed. Check this parameter when designing RF circuits or fast switching applications, and confirm it with the datasheet's test conditions.

Specifies the maximum steady-state current that can flow through the diode in the forward direction without exceeding its thermal limits. Compare this value with your circuit's operating current to ensure reliable performance. Always verify against the datasheet for derating curves and ambient temperature conditions.

Specifies the maximum transient reverse voltage a diode or rectifier can withstand without damage when applied as a single pulse. Compare this rating with your circuit's surge conditions and verify it against the datasheet to ensure reliable operation.

Specifies the maximum repetitive reverse voltage a diode or rectifier can handle without breakdown. Compare this rating with your circuit's peak reverse voltage to ensure reliable operation. Always verify against the datasheet for safety margins.

Indicates whether the component is original, aftermarket, or from another sourcing category. Buyers should verify this attribute to ensure supply chain authenticity and avoid counterfeit parts. Always cross-check with the datasheet and supplier documentation.

Harmonized Tariff Schedule of the United States code for customs classification. Essential for import/export documentation and duty calculation. Verify the correct code with a trade specialist to avoid customs delays.

Indicates whether the component complies with the EU RoHS directive restricting hazardous substances. Buyers should verify this status for regulatory compliance and market access. Check the datasheet or certificate for exact compliance details.

Marking is the code printed on the component body, used for identification and traceability. It often encodes part number, date code, or lot information. Verify it against the datasheet to confirm the exact variant and manufacturing details.
