DTC015EUBTL

Overview

The DTC015EUBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323FL-3 surface-mount package. It integrates bias resistors with a typical input resistance of 100 kOhms and a ratio of 1. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 100 mV, continuous collector current of 100 mA, and power dissipation of 200 mW. The device features a minimum DC current gain (hfe) of 80 at 5 mA and 10 V, a maximum operating frequency of 250 MHz, and an emitter-base voltage (VEBO) of 2.6 V. It supports operation up to +150°C.

Feature Summary

• Integrates built-in bias resistors for simplified circuit design
• Optimized for high-speed switching applications with 250 MHz frequency rating
• Compact SMD/SMT footprint suitable for space-constrained layouts

Applications

• General-purpose signal switching
• Driver circuits for low-power loads
• Logic level translation interfaces

Procurement Notes

Verify the specific suffix 'UBTL' against the manufacturer's official datasheet to confirm packaging details such as reel size or tape specifications. Ensure that the ordering part number matches the exact component variant required for the design, as suffixes may indicate differences in tape-and-reel configuration rather than functional changes. Cross-reference with authorized distributors for availability.

Selection Notes

Select this component when a single NPN digital transistor with high input impedance (100 kOhms) is required. The 100 mA collector current and 200 mW power dissipation define its load handling capability. Verify that the 100 mV VCEO rating aligns with the system's voltage requirements, as this value appears unusually low for standard logic levels and requires strict adherence to the official datasheet limits.

Part Context

This component belongs to the DTC015EUB series of digital transistors from ROHM Semiconductor. These devices are designed to replace discrete resistor-transistor combinations, reducing board space and assembly costs. The UMT3F package code corresponds to the SOT-323FL form factor, widely used in portable electronics and compact consumer devices.
