DDTC143ZCAQ-7-F

Overview

The DDTC143ZCAQ-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 = 4.7 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. Power dissipation is rated at 200 mW, with an operating temperature range from -55°C to +150°C. It utilizes a SOT-23 package and meets AEC-Q101 automotive reliability standards.

Feature Summary

Automotive-grade qualification compliant with AEC-Q101 standards for high reliability applications
Integrated unequal biasing resistors (R1 ≠ R2) simplify circuit design and reduce component count
Totally lead-free construction fully compliant with RoHS directives and halogen/antimony free

Applications

Automotive electronic systems requiring qualified discrete components
General-purpose switching and logic interface circuits
Driver stages for low-power loads in consumer electronics

Procurement Notes

Verify the specific 'Q' suffix indicates AEC-Q101 automotive qualification status during procurement. Confirm that the ordering quantity aligns with the standard reel size of 3,000 units per 7-inch tape width. Ensure compliance with PPAP requirements if mandated by the end-application specifications.

Selection Notes

Select this component when an NPN digital transistor with a 4.7 kΩ base resistor and 47 kΩ emitter resistor is required. The Q-suffix variant is necessary for automotive projects demanding AEC-Q101 certification. Verify that the 100 mA output current and 200 mW power dissipation meet the thermal and load requirements of the target application.

Part Context

This part belongs to the DDTC (R1≠R2 Series) CA family of pre-biased transistors. It shares electrical characteristics with the standard DDTC143ZCA-7-F but includes automotive-specific qualification markings. The series offers various resistor combinations within the same SOT-23 footprint to accommodate different drive requirements.
