2SA2205-E

Single Bipolar Transistors Overview

The onsemi 2SA2205-E is a PNP single bipolar junction transistor (BJT) designed for high-speed switching applications. It features an absolute maximum collector-to-emitter voltage of -100 V and a continuous collector current rating of -2 A. The device utilizes FBET and MBIT processes to achieve low collector-to-emitter saturation voltage, specifically -120 mV at -1 A collector current with -100 mA base drive. Key electrical characteristics include a DC current gain (hFE) ranging from 200 to 400, a gain-bandwidth product of 300 MHz, and a maximum power dissipation of 0.8 W at 25°C ambient temperature. The component is housed in the TP package (SC-64/TO-251) and supports a junction temperature up to 150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix to confirm the package type and shipping configuration. The 2SA2205-E designation corresponds to the TP package supplied in bags of 500 pieces. Confirm that the required RoHS compliance status matches the Pb Free specification listed in the datasheet. Ensure the procurement documentation explicitly references the ENA0544 datasheet for accurate technical validation before integration into designs.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor requires -100 V blocking capability combined with -2 A continuous current handling. The low saturation voltage makes it suitable for applications where minimizing conduction losses is critical. Consider the thermal constraints carefully, as the power dissipation drops significantly from 15 W at case temperature to 0.8 W at ambient temperature. Verify that the switching speed requirements align with the specified turn-on and fall times for the target circuit frequency.

Single Bipolar Transistors Part Context

This part belongs to the 2SA2205 series of PNP epitaxial planar silicon transistors manufactured by onsemi. It is distinct from surface-mount variants like the 2SA2205-TL-E, which uses the TP-FA package. The device is engineered for general-purpose switching in power electronics, leveraging specific semiconductor processes to balance high current handling with fast transient response capabilities.
