DTA123YCAT116

Overview

The DTA123YCAT116 is a PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates bias resistors with a typical input resistance of 2.2 kOhms and a resistor ratio of 4.5. The device supports a maximum collector current of -100 mA and operates up to a 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 power dissipation of 350 mW. It meets AEC-Q101 automotive qualification standards and functions within a junction temperature range up to +150°C.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design by eliminating the need for external input components.
• Features thin-film resistors that provide complete insulation, allowing for negative input biasing and reduced parasitic effects.
• Automotive qualified under AEC-Q101 standards for reliability in vehicle applications.

Applications

• Inverter circuits requiring simplified input configurations
• Automotive electronic systems meeting AEC-Q101 requirements
• General-purpose switching applications in consumer electronics

Procurement Notes

Verify the specific suffix 'T116' against the manufacturer's official datasheet to confirm reel specifications and tape-and-reel dimensions. Ensure compatibility with automated pick-and-place equipment regarding package tolerance. Cross-reference the AEC-Q101 certification status if the application mandates strict automotive grade compliance beyond standard industrial ratings.

Selection Notes

Select this component when a PNP configuration with a 2.2 kOhm base resistance is required in a compact SOT-23 form factor. Consider the -50 V collector-emitter voltage rating for low-voltage switching tasks. Verify that the 350 mW power dissipation capability aligns with the thermal management constraints of the target PCB layout and operating environment.

Part Context

This part belongs to the ROHM DTA series of digital transistors, which combine bipolar junction transistors with integrated bias networks. The DTA123 variant specifically denotes a PNP type with defined resistor ratios. The 'CAHZ' or similar internal codes often indicate specific material or processing variations within the broader DTA family, tailored for high-volume surface mount assembly.

Replacement Considerations

Direct substitutes may include other PNP digital transistors in SOT-23 packages with similar 2.2 kOhm input resistance and -50 V ratings, such as parts from ON Semiconductor or Diodes Inc., provided pinout and electrical characteristics match exactly.
