2SA2090TLQ

Single Bipolar Transistors Overview

The ROHM 2SA2090TLQ is a PNP silicon epitaxial planar medium power transistor designed for high-speed switching applications. It features a collector-emitter voltage (VCEO) of -60 V and a maximum continuous collector current (IC) of -0.5 A, with a power dissipation rating of 500 mW at 25°C ambient temperature. The device exhibits a typical fall time (Tf) of 35 ns at IC = 500 mA and a low saturation voltage of approximately -150 mV at IC = -100 mA. Packaged in the TSMT3 surface-mount configuration, it supports a junction temperature range up to 150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'TL' against the manufacturer's official documentation to confirm the taping packaging format and unit quantity. Ensure that the component meets all absolute maximum ratings for your operating environment. Cross-reference the datasheet revision date to confirm electrical characteristic consistency before finalizing procurement specifications.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with a -60 V breakdown voltage and 500 mA current capacity is required. It serves as a direct complement to the 2SC5868 NPN counterpart. Consider its low saturation voltage and fast fall time for applications demanding rapid switching transitions and minimal power loss during conduction states.

Single Bipolar Transistors Part Context
