DTD113ECHZGT116

Overview

The DTD113ECHZGT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SST3 (SOT-23-3) surface-mount package. It features built-in bias resistors with R1 at 1 kOhm and R2 at 10 kOhm. Key electrical parameters include a maximum collector-emitter voltage of 50 V, a continuous collector current of 500 mA, and a power dissipation rating of 200 mW. The device supports a transition frequency of 200 MHz and offers a minimum DC current gain of 82 at 50 mA and 5 V. It is qualified under AEC-Q101 standards for automotive applications.

Feature Summary

• Integrates bias resistors to simplify circuit design by eliminating external components.
• Utilizes thin-film resistors for complete insulation and negative input biasing capability.
• Minimizes parasitic effects due to the specific construction of the internal resistive elements.

Applications

• Inverter circuits
• Interface drivers
• Automotive-grade switching applications

Procurement Notes

Verify the exact suffix GT116 against the manufacturer's official datasheet to confirm packaging specifications and tape-and-reel dimensions. Ensure the component meets AEC-Q101 requirements if deployed in automotive systems. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a compact NPN switch with integrated biasing is required for high-frequency operation up to 200 MHz. The 500 mA current capacity suits moderate load driving tasks. Verify that the 1 kOhm base resistor value aligns with the specific drive current requirements of the controlling logic source.

Part Context
