DTA143XCAHZGT116

Overview

The DTA143XCAHZGT116 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 (SST3) surface-mount package. It integrates bias resistors with typical values of R1 = 4.7 kΩ and R2 = 10 kΩ. Key electrical parameters include a collector-emitter voltage (VCEO) of -50 V, a continuous collector current (Ic) of -100 mA, and a power dissipation (Pd) of 200 mW. The device features a transition frequency of 250 MHz and meets AEC-Q101 automotive qualification standards.

Feature Summary

• Integrates built-in biasing resistors to simplify circuit design by eliminating the need for external input components.
• Qualified under AEC-Q101 standards for high reliability in automotive applications.
• Designed for efficient operation in inverter, interface, and driver circuits.

Applications

• Automotive inverter circuits
• Interface logic circuits
• Driver circuits

Procurement Notes

Verify the specific suffix GT116 against official ROHM documentation to confirm reel packaging and tape specifications. Ensure the component meets AEC-Q101 requirements if used in automotive designs. Cross-reference datasheet revisions to confirm resistor tolerances and thermal characteristics match the intended application constraints before finalizing procurement.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for space-constrained designs. The SOT-23-3 package suits low-power applications needing 50V blocking capability. Verify that the 200mW power dissipation rating aligns with the thermal management strategy of the target system.

Part Context

This part belongs to the DTA143 series of pre-biased transistors from ROHM. It serves as the PNP counterpart to NPN variants like the DTC143XCAHZG. The series is engineered for automotive-grade reliability, offering a compact solution for switching applications where board space and component count are critical factors.

Replacement Considerations

Direct substitutes may include other PNP digital transistors with similar VCEO and Ic ratings. Verify pinout compatibility and internal resistor ratios. Check for equivalent AEC-Q101 qualification if automotive use is required.
