Overview
The DDTC124XCA-7-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 = 22 kΩ and R2 = 47 kΩ. The device operates within a supply voltage range up to 50 V and supports a continuous collector current of 100 mA. Electrical characteristics include a minimum DC current gain (hFE) of 68 at 5 mA, a transition frequency (fT) of 250 MHz, and a maximum power dissipation of 200 mW. It is housed in an SOT-23 package and complies with AEC-Q101 standards for high reliability.
Feature Summary
- Epitaxial planar die construction with integrated biasing resistors
- Qualified to AEC-Q101 automotive standards for high reliability
- Totally lead-free and fully RoHS compliant
- Halogen and antimony free "Green" device
Applications
- Automotive electronic circuits requiring AEC-Q101 compliance
- General-purpose switching applications
- Driver circuits for low-power loads
Procurement Notes
Verify the component against official datasheet DS30330 Rev. 11-2 specifications before integration. Confirm that the ordering suffix -7-F indicates standard reel packaging and RoHS compliance as documented by Diodes Incorporated. Ensure compatibility with existing PCB layouts designed for SOT-23 packages.
Selection Notes
Select this model when specific resistor ratios of 22 kΩ and 47 kΩ are required for base biasing. The 250 MHz transition frequency makes it suitable for higher-speed switching compared to lower-frequency alternatives. Verify thermal requirements against the 200 mW power dissipation limit under expected operating conditions.
Part Context
This component belongs to the DDTC (R1≠R2 Series) CA family from Diodes Incorporated. It represents a single NPN pre-biased transistor variant within a broader lineup offering various resistor combinations. The series provides standardized solutions for replacing discrete resistor networks in compact surface-mount designs.
Replacement Considerations
Direct substitutes within the same manufacturer's portfolio include other DDTC124 variants with different resistor values, such as DDTC124EUAQ-7-F or DDTC124TCA-7-F. Cross-manufacturer equivalents may exist but require verification of pinout, electrical ratings, and package dimensions.
