BC672S

Overview

The BC672S is a dual NPN general-purpose transistor manufactured by Diotec Semiconductor in an SOT-363 surface-mount package. It features a collector-emitter voltage (VCEO) of 18 V, a continuous collector current (IC) of 50 mA, and a power dissipation (Ptot) of 150 mW. The DC current gain (hFE) ranges from 100 to 200 at IC = 10 mA and VCE = 10 V. The device operates within a junction temperature range of -55°C to +150°C and has a transition frequency (fT) of 600 MHz.

Feature Summary

• Dual NPN transistors integrated into a single compact SMD package
• General-purpose design suitable for signal processing, switching, and amplification
• Compliant with RoHS, REACH, and Conflict Minerals regulations

Applications

• Signal processing circuits
• Electronic switching applications
• Amplification stages

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard version is commercial/industrial grade. Options such as -Q indicate AEC-Q101 compliance, while -AQ denotes parts currently undergoing automotive qualification. Confirm these suffixes match project requirements before procurement.

Selection Notes

Select this component for low-voltage NPN switching tasks requiring dual channels in minimal space. Ensure the circuit voltage does not exceed the 18 V collector-emitter rating. Verify that the required current gain falls within the 100 to 200 specification range for the intended operating conditions.

Part Context

This part belongs to the BC672 series of SMD general-purpose NPN transistors. It provides a dual-transistor solution in the SOT-363 footprint, offering a space-efficient alternative to discrete single transistors for commercial and industrial electronic designs.

Replacement Considerations

Check datasheets for other dual NPN transistors in the SOT-363 package. Verify that substitute components meet or exceed the 18 V VCEO, 50 mA IC, and 150 mW Ptot ratings.
