1085-MMBT100A

Overview

The onsemi MMBT100A is a general-purpose NPN silicon bipolar junction transistor (BJT) designed for surface-mount applications. It features a maximum DC collector current of 500 mA and a collector-emitter voltage rating of 40 V. The device operates within a temperature range of -55°C to +150°C, with a power dissipation capacity of 350 mW in an SOT-23 package.

Feature Summary

General-purpose NPN switching capability
High thermal stability up to 150°C
Compact SOT-23 surface-mount footprint

Applications

General-purpose switching circuits
Low-power amplifier stages
Signal processing interfaces

Procurement Notes

Verify the specific datasheet revision and ordering suffixes directly from onsemi official documentation before procurement. Confirm that the component meets all required environmental standards and RoHS compliance specifications for the intended application environment.

Selection Notes

Select this component for designs requiring standard NPN switching performance in space-constrained layouts. Ensure the circuit design accounts for the 350 mW power dissipation limit and the 40 V collector-emitter voltage breakdown under worst-case operating conditions.

Part Context

This part belongs to the MMBT series of small-signal transistors manufactured by onsemi. These components are widely utilized in consumer electronics and industrial control systems where reliable low-power switching and amplification are required in compact form factors.

Replacement Considerations

Consult official cross-reference guides for verified substitutes such as the MMBT3904 or MMBT2222A, ensuring pinout compatibility and electrical parameter alignment with the original design requirements.
