DTA013ZUBTL

Overview

The DTA013ZUBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors within an SOT-323FL-3 surface-mount package. It operates with a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes a typical input resistance 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 rated at 1 V, with a saturation output voltage of approximately 50 mV.

Feature Summary

• Integrates thin-film bias resistors to simplify inverter circuit design without external components.
• Provides complete isolation between resistors and transistor to eliminate parasitic effects.
• Supports negative biasing on the input due to isolated resistor construction.

Applications

• General-purpose logic level inversion circuits
• Driver circuits for low-current loads
• Interface applications requiring simplified bias networks

Procurement Notes

Verify the specific suffix 'UBTL' against the manufacturer's official datasheet to confirm the exact packaging configuration and tape-and-reel specifications. Ensure that the component meets RoHS compliance requirements for the intended market. Cross-reference the ordering number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a single NPN digital transistor with a 1 kOhm input resistance is required. The 50 V voltage rating and 100 mA current capacity suit low-power switching applications. Consider the SOT-323FL-3 package size for space-constrained designs. Verify that the 250 MHz transition frequency meets the signal speed requirements of the target application.

Part Context

This part belongs to the DTC013 series of digital transistors from ROHM Semiconductor. It serves as the NPN counterpart to the PNP DTA013 series. The device is designed as a standard product for general electronic equipment, distinct from automotive-grade variants which may carry different suffixes or qualification standards.

Replacement Considerations

The DTC013ZEB is listed as a similar specification alternative. Verify pinout compatibility and electrical parameter alignment before substitution. Check if the alternative package type matches the existing PCB footprint constraints.
