DTD114ECT116

Overview

The DTD114ECT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 (SST3) surface-mount package. It integrates bias resistors with a typical input resistance of 10 kOhms and an emitter-base resistance of 10 kOhms. The device supports a collector-emitter voltage of 50 V and a continuous collector current of 500 mA. Key electrical parameters include a minimum DC current gain of 56 at 50 mA and 5 V, a maximum operating frequency of 200 MHz, and a power dissipation rating of 200 mW. The saturation voltage is specified as 300 mV at 2.5 mA base current and 50 mA collector current.

Feature Summary

• Integrates built-in biasing resistors to simplify circuit design by eliminating the need for external input components.
• Provides high-speed switching capabilities suitable for applications requiring frequencies up to 200 MHz.
• Offers robust current handling with a 500 mA continuous collector current rating in a compact SOT-23-3 package.

Applications

• Inverter circuits and logic interface applications
• Driver circuits for relays and solenoids
• Gate drive circuits for power MOSFETs

Procurement Notes

Verify the specific suffix T116 to confirm the tape and reel packaging configuration containing 3,000 units per standard manufacturer roll. Ensure compatibility with SOT-23-3 footprint requirements during PCB layout. Confirm RoHS compliance status through official datasheets prior to final procurement decisions.

Selection Notes

Select this component when a single NPN pre-biased transistor with 500 mA current capacity is required. The 10 kOhm resistor ratio suits general-purpose switching tasks. Compare against DTC series variants if lower current ratings are sufficient or if different resistor values are needed for specific logic thresholds.

Part Context

This part belongs to the DTx series of digital transistors from ROHM Semiconductor. These devices combine bipolar junction transistors with internal bias networks to reduce board space and assembly complexity. The DTD114EC variant specifically denotes the NPN polarity with equal 10 kOhm bias resistors.

Replacement Considerations

Publicly confirmed substitute part numbers include DTD114ECMGT116. Verify pinout compatibility and electrical parameter equivalence before substitution.
