DTA144GU3T106

Overview

The DTA144GU3T106 is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors in a compact SOT-323 (UMT3) surface-mount package. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes an internal emitter-base resistor (R2) of 47 kOhms. Key electrical characteristics include a minimum DC current gain (hFE) of 68 at 5 mA and 5 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 200 mW. The component supports a maximum operating temperature of +150 C.

Feature Summary

• Integrates a single PNP transistor with a built-in 47 kOhm emitter-base bias resistor to simplify circuit design.
• Enables direct connection to logic outputs without external input resistors, facilitating inverter circuit configuration.
• Provides high-speed switching capabilities suitable for applications requiring operation up to 250 MHz.

Applications

• Inverter circuits
• Interface circuits
• Driver circuits

Procurement Notes

Verify the specific ordering suffix against official ROHM documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with JEITA SC-70 mechanical standards. Confirm RoHS compliance status through the manufacturer's latest specification sheets before finalizing procurement plans.

Selection Notes

Select this component when a PNP digital transistor with a single 47 kOhm internal resistor is required. Verify that the -50 V collector-emitter voltage and -100 mA current ratings meet the target application requirements. Consider the SOT-323 footprint constraints during PCB layout planning.

Part Context

This part belongs to the ROHM DTA144 series of Bias Resistor Built-in Transistors (BRBTs). These devices are designed to replace discrete transistor-resistor combinations, reducing board space and assembly costs. The series offers various resistance values and configurations for both NPN and PNP types.

Replacement Considerations

DTA144EUAFRA is listed as a similar level replacement with the same pinout and package. Verify functional equivalence and supply status, as some alternatives may carry 'not recommended for new designs' warnings.
