DDTC124TE-7-F

Overview

The DDTC124TE-7-F is an NPN pre-biased transistor from Diodes Incorporated, housed in a SOT523 package. It features a built-in biasing resistor (R1) with a nominal value of 22 kΩ. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 150 mW, with a thermal resistance of 833 °C/W. The DC current transfer ratio (hFE) ranges from 100 to 600 at IC = 1mA and VCE = 5V. The gain-bandwidth product is 250 MHz. Operating temperature spans -55°C to +150°C.

Procurement Notes

Verify the component status as active before procurement. Confirm compliance with RoHS 3 and REACH regulations if required by your region. Check the marking code N16 on the device to ensure authenticity. Ensure the reel size matches your pick-and-place equipment specifications. Validate that the SOT523 package dimensions fit your PCB layout constraints.

Selection Notes

Select this part when a single NPN transistor with a 22 kΩ base resistor is needed. Compare hFE ranges if precise gain control is critical for your application. Consider the 150 mW power dissipation limit for thermal management. Verify the 50 V voltage rating meets your circuit requirements. Evaluate the SOT523 package size against available board space.

Part Context

This component belongs to the DDTC (R1-ONLY SERIES) E family from Diodes Incorporated. It is designed as a complement to other digital transistors in the series. The series offers various resistor values for different biasing needs. All parts in this series share similar electrical characteristics and packaging options.

Replacement Considerations

Direct substitutes include other DDTC124 variants with identical R1 values. Check for equivalent packages like SOT-323 if pinout compatibility allows. Verify that replacement parts meet the same AEC-Q101 qualification if used in automotive contexts. Ensure the replacement maintains the 22 kΩ resistor tolerance.
