DTA143ZMT2L

Overview

The DTA143ZMT2L is a single PNP digital transistor manufactured by Rohm Semiconductor, housed in a VMT3 (SOT-723) surface-mount package. It integrates bias resistors to simplify circuit design. Key electrical parameters include a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 100 mA. The device features a minimum DC current gain (hFE) of 80 at 10 mA and 5 V, with a maximum saturation voltage of 300 mV at 250 µA base current and 5 mA collector current. Internal resistances are specified as R1 = 4.7 kΩ and R2 = 47 kΩ. Power dissipation is rated at 150 mW, with a transition frequency of 250 MHz.

Feature Summary

Integrates built-in bias resistors to eliminate external input resistor requirements for inverter circuits.
Utilizes thin-film resistors with complete isolation to allow negative biasing off the input and eliminate parasitic effects.
Provides simplified operation where only on/off conditions need to be set for circuit design.

Applications

Inverter circuits
Interface driver applications
General-purpose switching

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the component matches the intended surface-mount footprint specifications for the target PCB layout.

Selection Notes

Select this component when a compact PNP digital transistor solution is required for low-power switching applications. The integrated resistor network reduces board space and assembly steps compared to discrete BJT configurations. Verify that the 50 V voltage rating and 100 mA current capacity align with the specific load requirements of the design.

Part Context

This part belongs to the DTA143 series of pre-biased transistors from Rohm Semiconductor. It is designed as a complement to NPN counterparts within the same family. The VMT3 package offers a small form factor suitable for dense surface-mount assemblies. It serves as a standard-grade component for general electronic equipment rather than automotive-grade applications.
