DTC144VKAT146

Overview

The DTC144VKAT146 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SMT-3 (SOT-23) surface-mount package. It integrates bias resistors with a base resistance of 47 kOhms and an emitter resistance of 10 kOhms. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Key electrical parameters include a minimum DC current gain of 33 at 5 mA and 5 V, a transition frequency of 250 MHz, and a maximum power dissipation of 200 mW. The component is designated as not recommended for new designs.

Feature Summary

Integrates dual bias resistors to simplify circuit design
Optimized for high-speed switching applications
Designed for low-voltage digital logic interfacing

Applications

General-purpose digital switching circuits
Logic level translation interfaces
Driver circuits for small-signal loads

Procurement Notes

Verify the obsolete status before procurement, as the component is marked not recommended for new designs. Confirm availability through authorized distributors, noting that stock levels may be limited. Ensure the ordering suffix matches the required reel or cut tape format. Validate RoHS compliance and lead times directly with suppliers prior to finalizing orders.

Selection Notes

Select this component only for legacy system maintenance or specific replacement scenarios due to its discontinued status. Compare the integrated resistor values against alternative active devices if new designs are permissible. Verify that the 50 V rating and 100 mA current capacity meet the target application requirements without exceeding thermal limits.

Part Context

This part belongs to the DTC144 series of pre-biased NPN transistors from ROHM Semiconductor. The series is characterized by built-in bias resistors designed to reduce board space and assembly costs. The DTC144VKAT146 specifically utilizes the SMT-3 package variant within this family.
