DTD113EKFRAT146

Overview

The DTD113EKFRAT146 is a single NPN digital transistor manufactured by Rohm Semiconductor, designed for surface-mount applications in the SMT3 package. It integrates bias resistors to simplify circuit design. Key electrical parameters include a maximum collector-emitter voltage of 50 V and a continuous collector current of 500 mA. The device features a typical transition frequency of 200 MHz and a maximum power dissipation of 200 mW. Internal resistance values are specified as R1 = 1 kOhms and R2 = 1 kOhms. The saturation voltage is rated at 300 mV under specific test conditions, with a minimum DC current gain of 33 at 50 mA and 5 V.

Feature Summary

• Integrates built-in bias resistors to eliminate external input resistor requirements for inverter circuits.
• Utilizes thin-film resistors with complete insulation to enable negative input biasing.
• Minimizes parasitic effects through its integrated resistor construction.

Applications

• Digital logic interface circuits
• Inverter circuit configurations
• Automotive electronics (AEC-Q101 qualified)

Procurement Notes

Verify component authenticity against official Rohm Semiconductor documentation before integration. Confirm that the AEC-Q101 automotive qualification aligns with target application requirements. Check for end-of-life status or obsolescence notices, as availability may be restricted. Ensure packaging specifications match automated assembly line capabilities.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for low-power switching. The 50 V rating suits general-purpose signal processing. Verify thermal management needs against the 200 mW dissipation limit. Consider the SMT3 footprint constraints during PCB layout planning.
