DTC124ESA-BP

Overview

The DTC124ESA is an NPN digital transistor manufactured by Micro Commercial Components (MCC) in a TO-92S package. It integrates thin-film bias resistors to enable inverter circuit configuration without external input components. Key electrical parameters include a maximum supply voltage of 50 V, a peak output current of 100 mA, and a power dissipation rating of 300 mW. The device features a typical transition frequency of 250 MHz and a minimum DC current gain of 56. Internal resistance R1 has a typical value of 22 kΩ with a ratio of R2/R1 at 1.0. Operating temperatures range from -55°C to +150°C.

Feature Summary

• Built-in bias resistors allow for inverter circuit configuration without connecting external input resistors.
• Thin-film resistors provide complete isolation to eliminate parasitic effects and permit negative biasing of the input.
• Halogen-free versions are available upon request by adding the suffix "-HF".

Applications

• Inverter circuits
• Switching applications requiring simplified design

Procurement Notes

Verify authenticity through authorized distributors or direct MCC channels to avoid counterfeit parts. Confirm packaging type matches requirements, as the "-BP" suffix indicates bulk packing containing 100,000 pieces per carton. Ensure compliance with RoHS standards if required by the specific application constraints.

Selection Notes

Select this component when a single NPN digital transistor with integrated biasing is needed in a TO-92S package. Consider the 300 mW power dissipation limit and 250 MHz transition frequency for high-speed switching needs. Verify that the 50 V collector-emitter voltage meets the circuit's maximum operating requirements.

Part Context

This part belongs to the DTC124 series of NPN digital transistors produced by Micro Commercial Components. The "-BP" suffix specifically denotes bulk packaging, distinguishing it from tape-and-reel or ammo pack variants within the same product family.

Replacement Considerations
