DTC115EETL

Overview

The DTC115EETL is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-416 (EMT3) surface-mount package. It integrates bias resistors R1 and R2, both typically 100 kOhms with a ratio of 1, eliminating the need for external input components. The device supports a supply voltage up to 50 V and a continuous collector current of 100 mA. Key electrical parameters include a minimum DC current gain (hFE) of 82 at 5 mA and 5 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 150 mW. The saturation voltage is specified at 300 mV, with an emitter-base voltage of 3 V.

Feature Summary

• Integrates built-in thin-film bias resistors to simplify circuit design by removing the need for external input resistors.
• Features complete isolation between bias resistors to allow negative input biasing while minimizing parasitic effects.
• Utilizes a small SOT-416 surface-mount package to enable higher component mounting densities.

Applications

• Inverter circuits
• Interface logic drivers
• General-purpose switching applications

Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel packaging configuration, as variations exist within the product family. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required SOT-416 footprint for PCB layout compatibility.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for high-density designs. Compare against the DTA115EE series if a complementary PNP configuration is needed instead. Verify that the 100 mA collector current and 50 V voltage ratings meet the specific load requirements of the target application.

Part Context

This part belongs to the DTC115EE series of standard digital transistors invented and marketed by ROHM. It serves as a surface-mount alternative to larger packages like the DTC115EM. The device is classified as a standard-grade product and is not recommended for automotive equipment applications according to manufacturer guidelines.

Replacement Considerations

The DTC115EUAT106 is listed as a similar level replacement with the same pinout but utilizes a SOT-323 package. Designers must verify package dimension compatibility before substituting this component.
