DTC023JUBTL

Overview

The DTC023JUBTL is a single NPN digital transistor with built-in bias resistors, manufactured by Rohm Semiconductor. It features a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 100 mA. The device includes an internal base resistor (R1) of 2.2 kOhms and an emitter-base resistor (R2) of 47 kOhms. Key electrical characteristics include a DC current gain (hFE) of at least 80 at 5 mA and 10 V, a saturation voltage of 150 mV at 500 µA base and 5 mA collector current, and a transition frequency of 250 MHz. Power dissipation is rated at 200 mW. The component is housed in a UMT3F surface-mount package.

Feature Summary

• Integrates NPN bipolar junction transistor with dual internal bias resistors for simplified circuit design
• Provides high-speed switching capability with a 250 MHz transition frequency
• Offers low saturation voltage to minimize power loss during conduction
• Utilizes compact UMT3F surface-mount packaging for space-constrained applications

Applications

• General-purpose switching circuits
• Driver circuits for small loads
• Interface logic level translation

Procurement Notes

Verify the specific suffix UBTL against the manufacturer's datasheet to confirm the exact resistance values and package variant. Ensure the ordering quantity aligns with standard reel sizes if bulk procurement is required. Confirm RoHS compliance status matches project specifications before finalizing purchase orders.

Selection Notes

Select this component when a pre-biased NPN solution is needed to reduce external resistor count. The 2.2 kOhm base resistor suits moderate drive currents, while the 47 kOhm emitter resistor aids in leakage suppression. Verify that the 50 V rating and 100 mA current capacity meet the target circuit requirements.

Part Context

This part belongs to the DTC023 series of digital transistors from Rohm Semiconductor. The series offers various resistor combinations within the same UMT3F footprint, allowing designers to swap components without altering the PCB layout. The DTC023JUBTL specifically provides a fixed ratio of base to emitter resistance optimized for general switching tasks.

Replacement Considerations

Direct substitutes within the same family include DTC023YUBTL or DTC023ZUBTL, provided their internal resistor values match the circuit design requirements. Cross-manufacturer replacements require verification of pinout compatibility, hFE ranges, and thermal characteristics.
