DTC124XE3TL

Overview

The DTC124XE3TL is an NPN digital transistor from the ROHM DTC124X series, featuring built-in biasing resistors R1 (22 kΩ) and R2 (47 kΩ). It operates with a maximum collector current of 100 mA and a supply voltage of 50 V. The device utilizes an SOT-416 package and achieves a transition frequency of 250 MHz. Electrical characteristics include a DC current gain of at least 68 at 5 mA output, an input resistance of 22 kΩ, and a power dissipation rating of 150 mW.

Feature Summary

• Built-in biasing resistors enable inverter circuit configuration without external input components
• Simplifies circuit design by requiring only on/off condition settings for operation

Applications

• Inverter circuits
• Interface applications
• Driver circuits

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact packaging format and reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet revision before procurement. Ensure storage conditions adhere to humidity barrier bag requirements to maintain solderability.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for logic-level switching. Verify that the 50 V collector-emitter breakdown voltage meets the system's operational limits. Consider the complementary PNP DTA124X series if a matching negative polarity device is needed for push-pull configurations.

Part Context

This part belongs to the DTC124X series of Bias Resistor Built-in Transistors (BRBTs). The series offers various package options including SOT-723, SOT-416, and SOT-323. The DTC124XE3 variant specifically denotes the SOT-416 package configuration within this standardized product family.

Replacement Considerations

Consult the manufacturer's replacement guide for direct pin-compatible alternatives. The DTC124XEFRATL serves as a similar NPN option within the same series.
