BD234

Overview

The BD234G is a PNP plastic medium power bipolar transistor manufactured by onsemi. It features a collector-emitter voltage of 45 Vdc, a collector-base voltage of 60 Vdc, and an emitter-base voltage of 5.0 Vdc. The device supports a continuous collector current of 2.0 Adc and a base current of 1.0 Adc. Total device dissipation reaches 25 W at a case temperature of 25°C. Operating junction temperatures range from -55 to +150°C.

Feature Summary

Designed for use in 5.0 to 10 W audio amplifiers and drivers utilizing complementary or quasi-complementary circuits.
High DC current gain capability.

Applications

Audio amplifier circuits
Driver circuits

Procurement Notes

Verify the specific ordering suffix 'G' to confirm lead-free compliance and RoHS status. Confirm package style and pin configuration details against the TO-225 mechanical outline. Check current availability status as this device may be discontinued.

Selection Notes

Select the BD234G when a PNP counterpart is required for complementary designs alongside NPN variants like the BD237G. Ensure thermal management meets the 25 W dissipation requirement at 25°C case temperature. Verify that the 45 V collector-emitter rating suits the circuit voltage requirements.

Part Context

This component belongs to the BD23x series of plastic medium power bipolar transistors. It serves as the PNP complement to the NPN BD237G within the same datasheet specification. The series is engineered for medium-power applications requiring matched characteristics in push-pull configurations.

Replacement Considerations

Consult onsemi representatives for current alternatives as the BD234G is listed as discontinued. No direct public substitute part numbers are confirmed in the provided documentation.
