DTA143ZEBHZGTL

Overview

The DTA143ZEBHZGTL is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors in an SOT-416-3 surface-mount package. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes a typical input resistor (R1) of 4.7 kOhms and a typical resistor ratio of 10. Key electrical characteristics include a minimum DC current gain (hFE) of 80 at -10 mA and -5 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 150 mW. The emitter-base voltage is rated at -1.3 V, with a saturation output voltage of -100 mV.

Feature Summary

• Integrates a PNP bipolar junction transistor with a single bias resistor network for simplified circuit design.
• Provides high-speed switching capabilities suitable for applications requiring operation up to 250 MHz.
• Features a compact SMD/SMT footprint designed for automated assembly processes.

Applications

• General-purpose digital logic interface circuits
• Signal level shifting between different voltage domains
• Driver stages for small-signal loads

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact packaging and tape specifications. Confirm RoHS compliance status through the latest datasheet revision. Ensure the ordering part number matches the required reel or cut-tape configuration for your manufacturing line.

Selection Notes

Select this component when a PNP digital transistor with a 4.7 kOhm base resistor is required in a low-profile SOT-416 package. Consider the 150 mW power dissipation limit and -50 V voltage rating during thermal and voltage stress analysis. Verify that the 250 MHz frequency response meets the system's switching speed requirements.

Part Context

This component belongs to the DTA series of bias-resistor-built-in transistors from ROHM Semiconductor. These devices combine a BJT with internal resistors to reduce board space and simplify schematic design compared to discrete resistor-transistor combinations. The ZEB variant specifically denotes the SOT-416 package style within this product family.

Replacement Considerations

DTA143ZE3HZGT106 is listed as a recommended replacement with similar specifications and the same UMT3/SC-75a package type. Verify pinout compatibility before substitution.
