DTC123JE3TL

Overview

The DTC123JE3TL is an NPN digital transistor from the ROHM DTC123J series, housed in a SOT-416 (EMT3) surface-mount package. It integrates bias resistors R1 and R2 with a single NPN transistor to simplify circuit design. Key electrical parameters include a supply voltage (VCC) of 50 V, a maximum collector current (IC) of 100 mA, and a power dissipation (PD) of 150 mW at 25°C ambient temperature. The typical input resistance (R1) is 2.2 kΩ, and the typical resistance ratio (R2/R1) is 21. The device features a transition frequency (fT) of 250 MHz and a minimum DC current gain (hFE) of 80 at 10 mA and 5 V.

Feature Summary

• Built-in biasing resistors enable inverter circuit configuration without external input resistors.
• Simplifies circuit design by requiring only on/off condition settings for operation.
• Complementary PNP types available within the DTA123J series.

Applications

• Inverter circuits
• Interface applications
• Driver circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact packaging type and reel specifications. Confirm RoHS compliance status and ensure the component meets the required storage and handling conditions for electrostatic-sensitive devices prior to procurement.

Selection Notes

Select this component when a compact NPN digital transistor with integrated biasing is required for low-voltage logic interfacing. Ensure the application operates within the specified 50 V supply limit and 100 mA current capacity. Consider the SOT-416 footprint constraints and verify thermal derating requirements if operating above 25°C ambient temperature.

Part Context

This part belongs to the DTC123J series of Bias Resistor Built-in Transistors (BRBTs). The series includes various package options such as SOT-723, SOT-323, and SOT-346. The DTC123JE3 variant specifically utilizes the SOT-416 package, distinguishing it from other series members like the DTC123JM or DTC123JUB which use different physical footprints.

Replacement Considerations

Direct pin-compatible replacements within the same series include DTC123JM (SOT-723) and DTC123JEB (SOT-416FL), though package dimensions differ. For identical SOT-416 packages, verify availability of DTC123JE3 variants with different suffixes. Complementary PNP equivalents are found in the DTA123J series.
