DTD123ECHZGT116

Overview

The DTD123ECHZGT116 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 typical values of 2.2 kOhms for both base and emitter connections. The device supports a collector continuous current of 500 mA and a maximum operating frequency of 200 MHz. Key electrical ratings include a collector-emitter voltage of 50 V, an emitter-base voltage of 3 V, and power dissipation of 200 mW. It meets AEC-Q101 automotive qualification standards and operates within a 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.
• Automotive-grade reliability certified under AEC-Q101 standards for high-temperature operation.
• Optimized for high-speed switching applications with a transition frequency of 200 MHz.

Applications

• Inverter circuits
• Interface drivers
• General-purpose driver applications

Procurement Notes

Verify the specific suffix GT116 against official ROHM documentation to confirm reel packaging and tape specifications. Ensure compatibility with AEC-Q101 requirements if used in automotive contexts. Cross-reference datasheet revisions to validate thermal characteristics and pinout configurations before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. The 2.2 kOhm resistor configuration suits standard logic interface levels. Consider the 50 V rating and 500 mA current capacity against load requirements. Verify that the SOT-23-3 package fits the available PCB real estate and thermal management strategy.

Part Context

This part belongs to the ROHM DTx series of digital transistors, which combine bipolar junction transistors with internal bias networks. The DTD123 variant specifically denotes an NPN configuration with 2.2 kOhm resistors. It serves as a direct replacement for discrete BJT-resistor combinations, reducing board space and assembly complexity in modern electronic systems.

Replacement Considerations

DTD123ECT116 shares identical electrical parameters and package type but may differ in packaging format or specific manufacturing lot codes. Verify functional equivalence through cross-referencing official substitution lists from ROHM Semiconductor before implementation.
