DTA143ZCAHZGT116

Overview

The DTA143ZCAHZGT116 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates bias resistors with typical values of 4.7 kOhms for the input resistor and a ratio of 10. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of -30 V, a continuous collector current of -100 mA, and a power dissipation rating of 350 mW. The device features a minimum DC current gain (hfe) of 80 at -10 mA and -5 V, with a maximum operating frequency of 250 MHz. It is qualified under AEC-Q101 standards for automotive applications and operates within a temperature range up to +150°C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design by eliminating external components.
• Qualified for automotive reliability under AEC-Q101 standards.
• Utilizes thin-film resistors to minimize parasitic effects and allow positive input biasing.

Applications

• Inverter circuits
• Interface logic drivers
• General-purpose switching applications

Procurement Notes

Verify the specific suffix GT116 against the manufacturer's official datasheet to confirm reel specifications and tape-and-reel dimensions. Ensure compatibility with existing PCB footprints for the SOT-23-3 package. Confirm that the AEC-Q101 qualification meets the specific grade requirements for the target automotive application before finalizing procurement.

Selection Notes

Select this component when a compact PNP solution with integrated biasing is required for high-frequency switching up to 250 MHz. The -30 V rating and -100 mA current capacity suit low-voltage digital interfaces. Consider the complementary NPN type DTC143ZCAHZGT116 if an NPN configuration is needed for push-pull or differential stages.

Part Context

This part belongs to the DTA143 series of bias-resistor-built-in transistors from ROHM. It shares functional similarities with variants like DTA143XCAHZG and DTA143TCAHZG but differs in packaging and specific resistor ratios. The ZCAHZG suffix denotes the specific SOT-23 form factor and internal resistance network configuration unique to this ordering code.

Replacement Considerations

DTA143XCAHZGT116 offers similar specifications with a different resistor ratio configuration. DTC143ZCAHZGT116 serves as the complementary NPN counterpart. Verify pinout compatibility and exact resistance values when substituting with other DTA143 series members.
