DTC114YETL

Overview

The DTC114YETL is an NPN digital transistor manufactured by ROHM Semiconductor, housed in a surface-mount SOT-416 (EMT3) package. It integrates bias resistors to simplify circuit design without external input components. Key electrical parameters include a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 70 mA. The device features a built-in base resistor (R1) of 10 kOhms and an emitter-base resistor (R2) of 47 kOhms, resulting in a resistance ratio of approximately 4.7. It operates with a minimum DC current gain (hFE) of 68 at 5 mA and 5 V, supports a transition frequency of 250 MHz, and has a power dissipation rating of 150 mW across a temperature range of -55 °C to +150 °C.

Feature Summary

• Integrates bias resistors to enable inverter circuit configuration without external input resistors
• Features leak absorption type architecture for improved noise immunity
• Provides low saturation voltage characteristics suitable for switching applications

Applications

• Inverter circuits requiring simplified input stages
• General-purpose switching applications in consumer electronics
• Driver circuits for small signal loads

Procurement Notes

Verify the specific suffix 'ETL' against official ROHM documentation to confirm tape-and-reel packaging specifications and lead times. Ensure compatibility with RoHS3 standards if required by the target application. Cross-reference the part number with authorized distributors to confirm current production status and avoid obsolete variants.

Selection Notes

Select this component when an NPN digital transistor with a 10 kOhm base resistor and 47 kOhm emitter-base resistor is required. The SOT-416 package is suitable for space-constrained designs. Verify that the 70 mA collector current and 50 V voltage ratings meet the load requirements. Consider the DTA114YETL if a PNP polarity is needed instead.

Part Context

This component belongs to the ROHM DTC114 series of digital transistors, which are designed to replace discrete resistor-transistor combinations. The DTC114YETL specifically denotes the NPN variant with the EMT3 package code. It is part of a broader family including PNP counterparts like the DTA114YETL and other package options such as SOT-323.

Replacement Considerations

The DTA114YETL serves as the direct PNP counterpart within the same series. For alternative packages, the DTC114YE3TL offers similar electrical characteristics in the same SOT-416 form factor. Verify pinout compatibility before substituting.
