DTA143TMT2L

Overview

The DTA143TMT2L is a single PNP digital transistor manufactured by Rohm Semiconductor, featuring built-in bias resistors within a VMT3 (SOT-723) surface-mount package. It supports a collector-emitter voltage of 50V and a continuous collector current of 100mA. The device incorporates a base resistor (R1) of 4.7kΩ and an emitter-base resistor (R2) of 47kΩ. Key electrical characteristics include a DC current gain (hFE) of at least 80 at 10mA/5V, a saturation voltage of 300mV max at 250µA/5mA, and a transition frequency of 250MHz. Power dissipation is rated at 150mW.

Feature Summary

Integrates thin-film bias resistors to simplify inverter circuit design without external input components
Resistor isolation allows positive input biasing while minimizing parasitic effects
Operational control limited to on/off states for streamlined system configuration

Applications

Inverter circuits
Interface logic drivers
General-purpose switching applications

Procurement Notes

Verify the specific suffix TMT2L against the manufacturer's official datasheet to confirm the VMT3 packaging and tape-and-reel specifications. Ensure compliance with RoHS3 standards and check for AEC-Q101 automotive qualification if required for the target application environment.

Selection Notes

Select this component when a compact PNP digital transistor with a 4.7kΩ base resistor is needed. The VMT3 package suits high-density PCB layouts. Verify that the 100mA current rating and 50V breakdown voltage align with the load requirements and operating conditions of the intended circuit design.

Part Context

This part belongs to the DTA143 series of pre-biased transistors from Rohm Semiconductor. The series offers various packages including SOT-23 and SOT-323, but the TMT2L suffix specifically denotes the VMT3 form factor. It serves as a direct replacement for discrete resistor-transistor networks in space-constrained designs.
