DDTC124EUAQ-13-F

Overview

The DDTC124EUAQ-13-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors with nominal values of R1 = 22kΩ and R2 = 22kΩ. The device operates with a maximum supply voltage (VCC) of 50V and a continuous collector current (IC) of 100mA. Electrical characteristics include a DC current gain (hFE) minimum of 56 at VCE=5V, IC=5mA, and a transition frequency (fT) of 250MHz. Power dissipation is rated at 200mW, with an operating temperature range from -55°C to +150°C. It is housed in an SOT323 package.

Feature Summary

• Built-in biasing resistors simplify circuit design by eliminating the need for external input resistors.
• Qualified to AEC-Q101 standards for high reliability in automotive applications.
• Totally lead-free and fully RoHS compliant, containing no purposely added lead.
• Halogen and antimony free "Green" device construction.

Applications

• Automotive interface driving circuits
• Inverter circuits
• General purpose switching applications

Procurement Notes

Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm packaging quantity and compliance markings. Confirm that the component meets the required automotive qualification standards if used in vehicle systems. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the datasheet.

Selection Notes

Select this component when an NPN digital transistor with equal base and emitter resistors is required. Verify that the 22kΩ internal resistance values match the target logic interface specifications. Ensure the SOT323 package dimensions fit the available PCB footprint and that the 50V voltage rating exceeds the maximum circuit supply voltage.

Part Context

This part belongs to the DDTC (R1 = R2 Series) UA family of NPN pre-biased transistors. It shares electrical characteristics with other members of the series but differs in resistor values and package options. The 'Q' suffix indicates automotive qualification, while the '13-F' suffix denotes a 13-inch reel tape width and 10,000 units per reel.

Replacement Considerations

Complementary PNP types are available in the DDTA series. Other DDTC series members offer different resistor values such as 2.2kΩ or 47kΩ. Standard non-automotive versions like DDTC124EUA-7-F share identical electrical performance but lack the specific automotive PPAP capability.
