DTC114YE3TL

Overview

The DTC114YE3TL is an NPN digital transistor from the ROHM DTC114Y series, housed in a SOT-416 (EMT3) surface-mount package. It integrates biasing resistors R1 and R2 with a single NPN bipolar junction transistor to simplify circuit design. Key electrical parameters include a collector-emitter voltage of 50V, a maximum collector current of 100mA, and a power dissipation of 150mW at 25°C. The device features a typical DC current gain of 68 at 5mA/5V, a transition frequency of 250MHz, and built-in resistors of 10kΩ and 47kΩ.

Feature Summary

• Built-in biasing resistors eliminate the need for external input components, enabling direct configuration of inverter circuits.
• Simplified operation requires only setting on/off conditions, reducing complexity in circuit design.
• Low output saturation voltage facilitates efficient switching performance in interface and driver applications.

Applications

• Inverter circuits
• Interface logic
• Driver stages

Procurement Notes

Verify the specific ordering suffix against official ROHM documentation to confirm the exact packaging format and reel specifications. Ensure that the procurement channel provides authentic components with traceable manufacturing data. Confirm RoHS compliance status and long-term supply availability directly with the manufacturer or authorized distributors before finalizing orders.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for low-power switching. Verify that the 50V rating and 100mA current capacity meet the load requirements. Consider the complementary PNP DTA114Y series if a matched pair is needed. Ensure the operating temperature range aligns with the application environment.

Part Context

This part belongs to the DTC114Y series of digital transistors manufactured by ROHM Semiconductor. The series offers various package options including SOT-723, SOT-323, and SOT-346. The DTC114YE3 variant specifically utilizes the SOT-416 package, providing a balance between size and thermal performance for general-purpose electronic equipment.

Replacement Considerations

The complementary PNP type is the DTA114Y series. Other packages in the same electrical family include DTC114YM (SOT-723), DTC114YEB (SOT-416FL), and DTC114YUB (SOT-323FL). Verify pinout compatibility and thermal characteristics when substituting with these variants.
