DTD114GCT116

Overview

The DTD114GCT116 is a single NPN digital transistor from the ROHM DTx series, housed in an SOT-23-3 surface-mount package. It integrates built-in bias resistors to simplify circuit design. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 500 mA. The device features a typical input resistance of 10 kOhms and a minimum DC current gain (hFE) of 56 at 50 mA and 5 V. It supports a maximum operating frequency of 200 MHz with a power dissipation rating of 200 mW and a maximum operating temperature of +150 C.

Feature Summary

• Integrates built-in bias resistors to eliminate external input resistor requirements for inverter circuits.
• Designed for high-speed switching applications with a maximum operating frequency of 200 MHz.
• Supports high collector current capacity of 500 mA within a compact SOT-23-3 package.

Applications

• Inverter circuits
• Interface driving
• General-purpose switching

Procurement Notes

Verify the specific suffix 'T116' corresponds to the required tape-and-reel packaging configuration, as ordering suffixes define the shipping format rather than electrical function. Confirm that the standard production lead time aligns with project schedules, as manufacturing cycles may extend beyond immediate availability. Ensure compliance with RoHS directives and check for any specific REACH SVHC declarations relevant to the procurement region.

Selection Notes

Select this component when a single NPN digital transistor with 500 mA current handling and 50 V voltage rating is required. The 10 kOhm input resistance suits standard logic interface levels. Compare against the DTC114TCA for lower current needs or the DTA114TCA for PNP polarity requirements. Ensure the 200 mW power dissipation limit fits the thermal design constraints of the target application environment.

Part Context

This part belongs to the ROHM DTx series of digital transistors, which combine bipolar junction transistors with internal biasing networks. The series offers various configurations including different resistance ratios and polarities. The DTD114GCT116 specifically targets general-purpose switching applications requiring moderate current drive capabilities in a small outline transistor package.

Replacement Considerations

DTD114ECT116: Alternative variant within the same series with similar electrical characteristics but potentially different internal resistor ratios or packaging specifications. Verify pinout compatibility and exact parameter matches before substitution.
