BD135TG

Overview

The BD135TG is a discontinued plastic medium-power silicon NPN transistor manufactured by onsemi. It features a collector-emitter voltage of 45 V, a maximum DC collector current of 1.5 A, and a total device dissipation of 1.25 W at 25°C ambient temperature. The component utilizes the TO-225AA (TO-126) package with three pins. Electrical characteristics include a minimum DC current gain of 40 at 150 mA and 2 V, and a maximum collector-emitter saturation voltage of 0.5 V at 500 mA. Operating junction temperatures range from -55°C to +150°C.

Feature Summary

Designed for use in audio amplifiers and drivers utilizing complementary or quasi-complementary circuits
Complementary pairing available with BD136, BD138, and BD140 PNP transistors
Manufactured using lead-free, halogen-free, and BFR-free materials compliant with RoHS standards

Applications

Audio amplifier stages
Driver circuits in complementary configurations
Quasi-complementary circuit designs

Procurement Notes

Verify availability status as the BD135TG is officially listed as discontinued by onsemi and not recommended for new designs. Confirm specific revision details and substitute part numbers through authorized distributors before procurement planning. Ensure compliance with legacy design requirements if integrating into existing systems.

Selection Notes

Select this component only for replacement or maintenance purposes due to its discontinued status. Evaluate thermal management requirements carefully given the 1.25 W power dissipation limit at ambient conditions. Consider alternative active components for new product development to ensure long-term supply stability.

Part Context

This NPN transistor belongs to the BD135 series of plastic medium-power silicon devices. It is part of a family designed specifically for audio applications requiring complementary operation with corresponding PNP types. The series represents standard bipolar junction transistors used in general-purpose power switching and amplification tasks within defined voltage and current limits.
