BD137-16-BP

Overview

The BD137-16-BP is a PNP silicon epitaxial planar transistor manufactured by Micro Commercial Components (MCC). It is housed in a TO-92 package and designed for use in audio amplifiers and drivers utilizing complementary or quasi-complementary circuits. The device features a collector-emitter voltage rating of 45V, a continuous collector current of 800mA, and a maximum power dissipation of 625mW. It operates within a temperature range of -55°C to 150°C.

Feature Summary

• Epitaxial planar construction for reliable performance
• Designed for complementary and quasi-complementary circuit applications
• Pre-selected DC current gain for consistent amplification

Applications

• Audio amplifier stages
• Driver circuits
• Complementary switching applications

Procurement Notes

Verify the specific suffix '-16' against the official MCC datasheet to confirm the exact gain binning or voltage variant, as generic part numbers may encompass multiple sub-types. Ensure the TO-92 package style matches the target PCB footprint. Confirm RoHS compliance status if required by the manufacturing process.

Selection Notes

Select this component when a low-power PNP transistor with moderate current handling is needed for audio or driver stages. Compare its 800mA current rating and 45V voltage limit against circuit requirements. Consider the complementary BD136 NPN transistor for matched pairs in push-pull configurations.

Part Context

This component belongs to the BD13x series of power bipolar transistors from MCC. It serves as the PNP counterpart to the BD137 NPN type, forming part of a family designed for general-purpose amplification and switching tasks in consumer electronics and industrial control systems.

Replacement Considerations

The BD136 is the complementary NPN equivalent within the same MCC series. Other generic PNP transistors with similar 800mA/45V ratings in TO-92 packages may serve as functional substitutes if electrical parameters align.
