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.

Identifies the physical package type or designator, such as SOIC, QFN, or DIP. This determines PCB footprint, thermal performance, and assembly compatibility. Verify the package matches your board layout and manufacturing capabilities. Check the datasheet for exact dimensions.

Maximum collector-emitter voltage with the base open. This breakdown voltage defines the highest allowable voltage between collector and emitter without base connection. Engineers use it to ensure the transistor can withstand the supply voltage in the circuit. Check the datasheet for safe operating area.

Typical transition frequency of a transistor. This is the frequency at which the current gain drops to unity. It indicates the upper limit for useful amplification in high-frequency circuits. Engineers use it to select devices for RF and fast switching applications. Confirm with the datasheet's test conditions.

Maximum total power dissipation of the component. This is the highest power the device can dissipate without exceeding its junction temperature. Engineers use it to design thermal management and ensure reliability. Exceeding this limit can cause failure. Verify with the ambient temperature rating.

Minimum DC current gain of a bipolar transistor. This value indicates the lowest guaranteed amplification at a specified collector current and voltage. Engineers compare it to ensure sufficient drive capability in switching and amplification circuits. Always verify against the datasheet's test conditions.

Physical dimensions of the component in millimeters. Essential for PCB layout and mechanical fit. Buyers and engineers compare size to ensure the part fits the design envelope. Always check the datasheet for exact dimensions and tolerances.

Collector-emitter saturation resistance at specified collector current and base current ratio. This parameter indicates the on-state resistance when the transistor is fully saturated. Lower values reduce power loss and heat. Engineers compare it for high-current switching applications. Verify with the given IC and IC/IB conditions.

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.

Maximum collector-emitter saturation voltage. This is the voltage drop across the transistor when it is fully on. Lower values mean less power dissipation and better efficiency. Engineers compare it for low-voltage and battery-powered designs. Always check the specified collector current and base current.

Maximum collector-emitter saturation voltage for the second transistor in a dual or Darlington package. This parameter is critical when both transistors are used in parallel or complementary configurations. Engineers verify it to ensure balanced operation and minimal power loss. Check the datasheet for the specific test conditions.
