DTC113ZUAT106

Overview

The DTC113ZUAT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in the UMT3 (SC-70/SOT-323) surface-mount package. It integrates internal biasing resistors with a typical base resistance of 1 kOhm and an emitter resistance of 10 kOhm, yielding a resistor ratio of 10. Key electrical parameters include a maximum collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a transition frequency of 250 MHz. The device features a minimum DC current gain (hFE) of 33 at 5 mA and 5 V, a maximum power dissipation of 200 mW, and operates up to +150°C. It holds AEC-Q101 qualification for automotive reliability.

Feature Summary

• Integrates NPN bipolar junction transistor with built-in biasing resistors to simplify circuit design and reduce component count.
• Optimized for high-speed switching applications with a transition frequency of 250 MHz.
• Qualified under AEC-Q101 standards for use in automotive electronic systems.

Applications

• Automotive control circuits requiring AEC-Q101 qualified components
• General-purpose switching and logic interface applications
• Driver circuits for low-power loads

Procurement Notes

Verify the complete part number including suffixes such as 'T106' against official ROHM documentation to ensure correct tape-and-reel packaging specifications. Confirm that the UMT3 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact SOT-323 form factor is required for NPN switching with integrated base drive. Ensure the 1 kOhm input impedance aligns with the driving source capabilities. Verify that the 50 V breakdown voltage exceeds the maximum circuit operating voltage under all transient conditions.

Part Context

This part belongs to the ROHM DTx series of pre-biased transistors, which combine discrete transistors with internal resistors. The DTC113 variant specifically denotes an NPN configuration with a 1 kOhm base resistor and 10 kOhm emitter resistor, designed for efficient level shifting and switching in space-constrained designs.

Replacement Considerations

Direct substitutes may include other ROHM parts within the DTC113 family with different packaging or suffixes, provided the electrical characteristics and pinout remain identical. Cross-manufacturer replacements require verification of hFE, VCEO, and package compatibility.
