DTC115EUBTL

Overview

The DTC115EUBTL is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323FL (UMT3F) surface-mount package. It integrates bias resistors with a typical ratio of 1:1, featuring R1 and R2 values of 100 kOhms each. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, continuous collector current of 100 mA, and power dissipation of 200 mW. The device offers a minimum DC current gain (hFE) of 82 at 5 mA/5 V, a transition frequency of 250 MHz, and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates built-in bias resistors to eliminate external resistor requirements for inverter circuit configurations.
• Provides high-speed switching capabilities suitable for applications requiring a 250 MHz transition frequency.
• Features a compact SOT-323FL surface-mount footprint designed for space-constrained PCB layouts.

Applications

• General-purpose signal inversion circuits
• Driver circuits for small-signal loads
• Logic level translation interfaces

Procurement Notes

Verify the specific suffix 'UBTL' corresponds to the UMT3F package and tape-and-reel quantity of 3000 units. Confirm RoHS compliance status and ensure the component meets the required operating temperature range for the target environment. Cross-reference the manufacturer part number against authorized distributor catalogs to validate authenticity and supply chain integrity before procurement.

Selection Notes

Select this component when a single NPN digital transistor with a 100 kOhm input resistance is required. Ensure the design accommodates the 200 mW power dissipation limit and the 50 V collector-emitter voltage rating. Verify that the SOT-323FL package dimensions fit the available board space and that the 250 MHz frequency response meets the signal processing requirements.

Part Context

This part belongs to the DTC115 series of pre-biased transistors from ROHM Semiconductor. It serves as a standard-level discrete solution for replacing multiple discrete components with a single integrated unit. The series includes complementary PNP variants and alternative packaging options such as SOT-416 and SC-59.

Replacement Considerations

Direct substitutes include the DTA115EUBTL (complementary PNP version) and other DTC115 series variants like DTC115EU3T106 or DTC115GU3T106, provided the package type and electrical ratings match the original design requirements.
