BC369

Single Bipolar Transistors Overview

The onsemi BC369 is a PNP amplifier transistor housed in a TO-92 (TO-226) through-hole package. It features a maximum collector-emitter voltage of 20 Vdc and a continuous collector current rating of 1.0 Adc. The device provides a total power dissipation of 625 mW at 25°C ambient temperature, with a thermal resistance junction-to-ambient of 200 °C/W. Electrical characteristics include a DC current gain ranging from 85 to 375 at 0.5 A and 1.0 V, and a bandwidth product of 65 MHz. Operating temperatures span from -55°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm packaging type and lead-free status. Confirm RoHS compliance requirements as standard versions may differ from Pb-Free variants. Check component availability status, as this part number may be subject to discontinuation notices or production changes documented in public PCNs.

Single Bipolar Transistors Selection Notes

Select the BC369 when a PNP counterpart to the BC368 NPN transistor is required within the same family. Ensure the design accommodates the 20 V collector-emitter breakdown limit and 1 A current capacity. Verify that the TO-92 package dimensions fit the PCB layout constraints and that the thermal management strategy supports the specified power dissipation limits under operating conditions.

Single Bipolar Transistors Part Context

The BC369 belongs to the BC36x series of amplifier transistors manufactured by onsemi. This series pairs the BC368 (NPN) with the BC369 (PNP) to provide complementary symmetry for push-pull configurations. The components are engineered for linear and switching operations in consumer and industrial electronics, utilizing silicon planar technology for reliable performance.
