DTD114GCHZGT116

Overview

The DTD114GCHZGT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, designed for surface-mount applications in the SST3 (SOT-23-3) package. It integrates bias resistors to simplify circuit design, featuring a typical input resistance of 10 kOhms. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 500 mA. Key electrical parameters include a minimum DC current gain (hFE) of 56 at 50 mA and 5 V, a maximum operating frequency of 200 MHz, and a power dissipation rating of 200 mW. It operates within a temperature range up to +150°C and meets AEC-Q101 automotive standards.

Procurement Notes

Verify the specific suffix GT116 against the official datasheet to confirm packaging details such as reel size or tape specifications. Ensure the component meets the required AEC-Q101 qualification if used in automotive contexts. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit parts. Confirm lead times and production cycles directly with the supplier prior to ordering.

Selection Notes

Select this component when an NPN digital transistor with 500 mA current capacity and 50 V voltage rating is required. The integrated 10 kOhm input resistor simplifies base drive calculations. Consider the 200 mW power dissipation limit and thermal management requirements for the SOT-23-3 package. Verify compatibility with existing PCB footprints for the SST3 package type.

Part Context

This part belongs to the DTx series of digital transistors from ROHM Semiconductor. It is specifically engineered for automotive and industrial applications requiring high reliability. The DTD114GC variant represents the NPN polarity within this family, offering complementary solutions alongside PNP types like the DTA114 series.

Replacement Considerations

Check for direct substitutes within the ROHM DTD114 series that may offer different resistor ratios or packages. Verify pinout compatibility before replacing with other manufacturers' NPN digital transistors rated for 50V/500mA in SOT-23-3 packages.
