DTA123YCAHZGT116

Overview

The DTA123YCAHZGT116 is a PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates bias resistors with typical values of 2.2 kOhms for R1 and 10 kOhms for R2, yielding a ratio of 4.5. The device supports a continuous collector current of -100 mA and operates up to a maximum frequency of 250 MHz. Key electrical limits include a collector-emitter voltage (VCEO) of -50 V, an emitter-base voltage (VEBO) of -3 V, and a power dissipation rating of 350 mW. It meets AEC-Q101 automotive qualification standards and functions within a temperature range extending to +150 C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design by eliminating the need for external input components.
• Automotive-grade reliability certified under AEC-Q101 standards for high-temperature operation.
• Thin-film resistor construction provides complete isolation, enabling negative biasing and minimizing parasitic effects.

Applications

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

Procurement Notes

Verify the specific suffix GT116 against the target datasheet revision to ensure compatibility with required packaging formats such as cut tape or reel. Confirm that the 2.2k/10k resistor configuration matches the schematic requirements. Check for RoHS compliance status and ensure the SOT-23-3 footprint aligns with the PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with a 2.2k base resistor is required for automotive or industrial environments. The 100 mA current capacity suits low-to-medium load switching tasks. Compare against complementary NPN types like DTC123YCAHZG if both polarities are needed. Ensure the 350 mW power dissipation rating accommodates the thermal conditions of the intended application.

Part Context

This part belongs to the DTA123 series of pre-biased transistors from ROHM Semiconductor. It shares the same internal circuit topology and pinout with variants differing primarily in resistor values or packaging suffixes. The HZG designation indicates the specific automotive-grade version housed in the SST3 (SOT-23) package, distinguishing it from standard commercial grades.

Replacement Considerations

Direct substitutes include other ROHM parts with identical resistor ratios and polarity, such as DTA123YCAHZG. Verify that any replacement maintains the -50 V VCEO rating and -100 mA Ic limit. Cross-reference pinouts to ensure Pin 1 (Emitter), Pin 2 (Base), and Pin 3 (Collector) alignment remains consistent.
