DTC124ESA-AP

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 continuous output current of 30 mA with a peak of 100 mA, and a power dissipation rating of 300 mW at 25°C. The device features a typical transition frequency of 250 MHz and a DC current gain of 56. Internal resistance R1 is typically 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 input biasing.
• Simplified design process where only on/off conditions require setting for operation.

Applications

• Inverter circuits
• Switching applications requiring simplified bias networks
• General-purpose digital logic interfacing

Procurement Notes

Verify the specific ordering suffix to confirm packaging type and compliance status. The standard part number indicates bulk or ammo packing options. Confirm RoHS compliance through the designated suffix if required. Ensure procurement channels are authorized distributors to guarantee genuine parts and full traceability as per manufacturer guidelines.

Selection Notes

Select this component when a TO-92S through-hole package is required for NPN digital switching. Consider the 300 mW power dissipation limit and 250 MHz transition frequency for high-speed applications. Verify that the integrated 22 kΩ input resistance matches the driving source requirements. Check thermal derating curves for ambient temperature constraints above 25°C.

Part Context

This component belongs to the DTC124 series of NPN digital transistors produced by MCC. It shares functional similarities with other members of the family but differs in package style and specific electrical tolerances. The TO-92S form factor distinguishes it from surface-mount variants like SOT-23 or SOT-323 packages found in other series models.

Replacement Considerations

Direct substitutes must match the NPN polarity, TO-92S package, and similar electrical ratings (50V, ~30mA). Verify pinout compatibility (GND, OUT, IN) before substitution. Cross-reference with other manufacturers' NPN digital transistors offering comparable transition frequencies and internal resistor values.
