DTA143TEBTL

Overview

The DTA143TEBTL is a PNP digital transistor manufactured by Rohm Semiconductor, featuring built-in bias resistors within an EMT3 surface-mount package. It operates with a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device integrates a base resistor (R1) of 4.7 kOhms and an emitter resistor (R2) of 10 kOhms. Key electrical characteristics include a DC current gain (hFE) of at least 100 at 10 mA and 5 V, a saturation voltage of 300 mV at specific test conditions, and a transition frequency of 250 MHz. Maximum power dissipation is rated at 150 mW.

Feature Summary

• Integrates thin-film bias resistors to enable inverter circuit configuration without external input components.
• Resistor isolation eliminates parasitic effects and allows for positive input biasing.
• Simplifies design by requiring only on/off condition settings for operation.

Applications

• Inverter circuits
• Interface logic
• Driver stages

Procurement Notes

Verify the exact suffix against the manufacturer's latest datasheet to confirm pinout and resistance values. Confirm RoHS3 compliance and moisture sensitivity level prior to assembly. Check for any specific handling requirements associated with the EMT3 package type during soldering processes.

Selection Notes

Select this component when a compact PNP switching solution with integrated biasing is required. Ensure the 100 mA current rating and 50 V breakdown voltage meet the circuit demands. Verify that the 4.7 kOhm base resistor value aligns with the driving source impedance and desired switching speed.

Part Context

This part belongs to the DTA143X series of digital transistors from Rohm. It shares the same core electrical specifications as other variants in the family but differs in packaging or specific resistance tolerances. The EMT3 package provides a small footprint suitable for dense PCB layouts.

Replacement Considerations

DTA143XE3TL is a confirmed substitute from Rohm Semiconductor.
