DTA143EE3HZGTL

Overview

The DTA143EE3HZGTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors in an SOT-416 (EMT3) surface-mount package. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes two internal resistors, R1 and R2, both typically rated at 4.7 kΩ, providing a resistance ratio of 1. Key electrical characteristics include a minimum DC current gain (hFE) of 30 at -10 mA and -5 V, a maximum operating frequency of 250 MHz, and a power dissipation capacity of 150 mW. It is qualified under AEC-Q101 standards for automotive applications.

Feature Summary

• Integrates dual bias resistors to simplify circuit design by eliminating external input components.
• Utilizes thin-film resistor technology for complete isolation and minimized parasitic effects.
• Complies with AEC-Q101 automotive grade reliability standards.

Applications

• Automotive interface circuits
• Driver stages for inverters
• General-purpose switching applications

Procurement Notes

Verify the specific suffix 'E3HZGT' against official ROHM documentation to confirm the reel packaging configuration and tape-and-reel specifications. Ensure the component meets the required AEC-Q101 qualification level for the intended automotive application environment before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with equal bias resistors (R1=R2=4.7kΩ) is required in a compact SOT-416 package. It is suitable for designs needing -50V blocking capability and -100mA drive current with integrated biasing to reduce board space and assembly complexity.

Part Context

This part belongs to the DTA143 series of pre-biased transistors from ROHM. It shares the same functional block as other variants like DTA143ZE3HZGTL but differs in package type (SOT-416 vs SOT-416/EMT3 variations) and specific automotive qualification markings. It is distinct from NPN counterparts such as the DTC144 series.

Replacement Considerations

Direct pin-compatible substitutes within the same family include DTA143EE3HZG. Verify that any alternative maintains the identical -50V rating, -100mA current limit, and 4.7kΩ resistor values to ensure circuit compatibility without redesign.
