DTC013ZUBTL

Overview

The DTC013ZUBTL is an NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes a typical input resistor of 1 kOhm and a resistor ratio of 10. Key electrical parameters include a minimum DC current gain (hFE) of 30 at 5 mA and 10 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 200 mW. The emitter-base voltage is specified at 1 V, with a saturation output voltage of 50 mV. It is housed in an SOT-323FL-3 surface-mount package.

Feature Summary

• Integrates thin-film bias resistors for complete isolation, enabling negative biasing without external components.
• Eliminates parasitic effects through isolated internal resistor construction.
• Simplifies circuit design by requiring only on/off condition settings for operation.

Applications

• Inverter circuits utilizing built-in biasing
• General-purpose switching applications
• Digital logic interface circuits

Procurement Notes

Verify the specific suffix UBTL against the official ROHM datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure compliance with RoHS standards as indicated in manufacturer documentation. Confirm availability and lead times directly with authorized distributors or the manufacturer, as supply status may vary. Validate that the SOT-323FL-3 package dimensions fit the intended PCB layout constraints.

Selection Notes

Select this component when a compact NPN digital transistor with low input resistance (1 kOhm) is required. The 50 V rating suits general low-voltage switching tasks. Consider the complementary PNP type, DTA013Z series, if push-pull configurations are needed. Verify that the 200 mW power dissipation is sufficient for the thermal environment. Ensure the 250 MHz frequency response meets the signal speed requirements of the application.

Part Context

The DTC013ZUBTL belongs to the DTC013 family of digital transistors from ROHM Semiconductor. This series is characterized by integrated bias resistors designed to reduce component count and board space. The UBTL suffix denotes the specific SOT-323FL-3 packaging variant. It is part of ROHM's standard digital transistor lineup, distinct from their power MOSFETs or voltage detectors.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult the official ROHM datasheet for recommended replacements or cross-reference with other manufacturers offering equivalent NPN digital transistors with similar 1 kOhm input resistance and 50 V ratings.
