DTA144EUBHZGTL

Overview

The DTA144EUBHZGTL is a PNP Bias Resistor Built-in Transistor (BRT) manufactured by ROHM Semiconductor. It integrates a single NPN transistor with two internal resistors in an SMD/SMT UMT3F (SOT-323FL) package. Key electrical parameters include a collector-emitter voltage of -50 V, a continuous collector current of -100 mA, and a power dissipation of 200 mW. The device features typical input resistance values of 47 kOhms for both R1 and R2, with a resistor ratio of 1. It operates at a maximum frequency of 250 MHz and has a minimum DC current gain (hFE) of 68. The component is qualified under AEC-Q101 standards and supports a maximum operating temperature of +150 C.

Feature Summary

• Integrates a PNP transistor with dual bias resistors to simplify circuit design and reduce component count.
• Provides high-speed switching capabilities suitable for digital logic interfaces and signal processing applications.
• Features a compact surface-mount package designed for automated assembly and space-constrained PCB layouts.

Applications

Procurement Notes

Verify the specific ordering suffix and packaging configuration when sourcing, as availability may vary by distributor. Confirm that the component meets the required AEC-Q101 qualification if used in automotive contexts. Check for any end-of-life notices or recommended alternative part numbers from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a PNP BRT with 47 kOhm internal resistors is required. Ensure the -50 V collector-emitter voltage rating exceeds the maximum circuit voltage. Verify that the -100 mA collector current capability matches the load requirements. Consider the UMT3F package dimensions for PCB footprint compatibility.
