DTA043ZMT2L

Overview

The DTA043ZMT2L is a PNP digital transistor with built-in resistors manufactured by ROHM Semiconductor. It features an integrated bias resistor network consisting of R1 (4.7 kΩ) and R2 (47 kΩ), enabling simplified inverter circuit configurations without external input components. The device operates with a collector-emitter voltage (VCEO) of -50 V and a maximum continuous collector current (Ic) of -100 mA. Key electrical parameters include a DC current gain (hFE) of at least 80 at Ic = -10 mA and Vce = -5 V, a transition frequency (fT) of 250 MHz, and a power dissipation rating of 150 mW. It is housed in the compact VMT3 (SOT-723) surface-mount package.

Feature Summary

• Integrated thin-film bias resistors eliminate the need for external input components, simplifying circuit design.
• Resistor isolation allows for negative input biasing while eliminating parasitic effects.
• High-speed switching capability supported by a 250 MHz transition frequency.

Applications

• Inverter circuits requiring minimal external component count
• General-purpose switching applications in consumer electronics
• Interface circuits between logic gates and loads

Procurement Notes

Verify the specific suffix 'ZMT2L' to confirm the VMT3 package and tape-and-reel packaging format. Ensure compatibility with RoHS standards if required by the target application. Confirm that the component status is active for new designs, as some variants in this series may be marked as not recommended for new designs.

Selection Notes

Select this component when a PNP digital transistor with a 4.7 kΩ base resistor and 47 kΩ emitter-base resistor is required. Verify that the -50 V voltage rating and -100 mA current capacity meet the load requirements. Consider the VMT3 package dimensions for PCB layout constraints compared to other SOT packages.

Part Context

This part belongs to the DTA043Z series of digital transistors from ROHM Semiconductor. The series includes complementary NPN types, such as the DTC043Z, which share similar internal resistance values but differ in polarity. The ZMT2L suffix specifically denotes the VMT3 surface-mount package configuration.

Replacement Considerations

Direct substitutes within the same family include DTA043XMT2L, though it features different resistor values (R1=4.7kΩ, R2=10kΩ). Cross-vendor equivalents should be verified for matching hFE, fT, and package dimensions.
