DTB113ECHZGT116

Overview

The DTB113ECHZGT116 is a PNP digital transistor manufactured by Rohm Semiconductor, featuring built-in biasing resistors within an SST3 (SOT-23) surface-mount package. It operates with a collector-emitter voltage of -50V and a continuous collector current of -0.5A. The device includes a base input resistor (R1) of 1kΩ and an emitter-base resistance (R2) of 1kΩ. Key electrical characteristics include a DC current gain (hFE) of at least 33 at 50mA and 5V, a saturation voltage of 300mV maximum at 2.5mA base current and 50mA collector current, and a transition frequency of 200MHz. Power dissipation is rated at 200mW.

Feature Summary

• Integrates PNP bipolar junction transistor with thin-film biasing resistors for simplified circuit design
• Provides complete insulation to allow positive direction input biasing while minimizing parasitic effects
• Designed for high-frequency applications with a transition frequency of 200MHz

Applications

• Inverter circuits requiring pre-biased switching
• Interface logic level translation
• Driver circuits for low-power loads

Procurement Notes

Verify the specific suffix GT116 corresponds to the tape and reel packaging format containing 3000 units per standard manufacturer roll. Confirm RoHS3 compliance and AEC-Q101 automotive qualification status through official datasheets before integration into production designs.

Selection Notes

Select this component when a PNP configuration with 1kΩ internal biasing resistors is required in a compact SOT-23 footprint. Ensure the -50V collector-emitter voltage rating meets the system's supply requirements and that the 200mW power dissipation limit accommodates thermal constraints under expected operating conditions.

Part Context

This part belongs to Rohm's DTB series of digital transistors, which combine single NPN or PNP transistors with integrated bias resistors. The DTB113 variant specifically denotes a PNP type with 1kΩ/1kΩ resistor values. The HZ suffix typically indicates automotive-grade reliability standards compliant with AEC-Q101.

Replacement Considerations

DTB113ECHZGT116 is listed as a parameter-equivalent substitute for the DTB113ECT116. Verify pinout compatibility and exact electrical tolerances against original design specifications before substitution.
