DTC124XEFRATL

Overview

The DTC124XEFRATL is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an EMT3 (SOT-416) surface-mount package. It integrates bias resistors with typical values of R1 at 22 kOhms and R2 at 47 kOhms. The device supports a collector-emitter voltage of 50V and a continuous collector current of 100mA. Key electrical parameters include a DC current gain (hFE) minimum of 68 at 5mA/5V, a transition frequency of 250MHz, and power dissipation of 150mW. It meets AEC-Q101 automotive qualification standards.

Feature Summary

• Integrates built-in biasing resistors to simplify circuit design by eliminating the need for external input components.
• Qualified for automotive applications under the AEC-Q101 standard for reliability.
• Provides high-speed switching capabilities suitable for digital logic interfaces.

Applications

• Automotive electronic control units requiring qualified discrete components
• Digital inverter circuits and logic level shifting
• Switching applications in consumer electronics

Procurement Notes

Verify the specific suffix FRATL against the manufacturer's datasheet to confirm the exact reel quantity and tape specifications. Ensure the ordering part number matches the required packaging format, such as cut tape or full reels, as availability may vary by distributor channel. Cross-reference the RoHS status and automotive grade certification requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. The SOT-416 package offers a small footprint compared to larger through-hole alternatives. Consider the 50V rating and 100mA current limit to ensure compatibility with the target load conditions and voltage levels within the system architecture.

Part Context

This part belongs to the DTC124X series of pre-biased transistors from ROHM Semiconductor. The series includes complementary PNP types like the DTA124XEFRATL. These devices are designed to replace multiple discrete components, reducing board space and assembly costs while maintaining consistent electrical characteristics across production batches.

Replacement Considerations

The DTC124XE3HZGT106 is listed as a similar level replacement with the same pinout and package. Verify that the alternative part maintains the same resistor ratios and electrical ratings before substitution.
