Overview
The DDTC124TEQ-7-F is an NPN pre-biased transistor from the DDTC (R1-ONLY SERIES) E, manufactured by Diodes Incorporated. It features a built-in biasing resistor R1 with a nominal value of 22 kΩ and a tolerance of ±30%. The device is housed in a SOT523 surface-mount package. Key electrical ratings include a collector-emitter voltage (VCEO) of 50 V, a collector current (IC) of 100 mA, and power dissipation (PD) of 150 mW. The DC current transfer ratio (hFE) ranges from 100 to 600 at IC = 1mA and VCE = 5V. The gain-bandwidth product (fT) is typically 250 MHz. Operating temperature range spans from -55°C to +150°C.
Feature Summary
- Built-in single biasing resistor (R1 only) simplifies circuit design
- AEC-Q101 qualified for automotive applications requiring specific change control
- Totally lead-free and fully RoHS compliant
- Halogen and antimony free "Green" device
Applications
- Automotive electronics requiring AEC-Q101 qualification
- General-purpose switching applications
- Driver circuits for low-power loads
Procurement Notes
Verify the part number suffix 'Q' indicates AEC-Q101 automotive qualification and PPAP capability as specified in the ordering information table. Confirm compliance with IATF 16949 certified manufacturing facilities requirements if applicable to your supply chain standards. Ensure packaging details match the reel size and tape width specifications provided in the datasheet.
Selection Notes
Select this component when a single NPN pre-biased transistor with a 22 kΩ base resistor is required in a compact SOT523 package. Consider the ±30% tolerance on the input resistor R1 for biasing calculations. Verify that the 50 V collector-emitter voltage and 100 mA collector current meet the load requirements. Check thermal resistance and power dissipation limits under expected operating conditions.
Part Context
This part belongs to the DDTC (R1-ONLY SERIES) E family, which includes various resistor values ranging from 1 kΩ to 200 kΩ. The 'Q' suffix denotes automotive grade qualification. Other variants like DDTC124TE-7-F share similar electrical characteristics but lack the specific automotive certification. The series offers complementary PNP types (DDTA) for push-pull configurations.
Replacement Considerations
Direct substitutes within the same series include DDTC124TE-7-F for standard commercial use. For automotive applications requiring identical qualification, ensure any replacement also carries the 'Q' suffix and meets AEC-Q101 standards. Verify pinout compatibility and package dimensions (SOT523) before substitution.
