ACDSQC4148-HF

Overview

The ACDSQC4148-HF is a standard small-signal switching diode manufactured by Comchip Technology. It features a maximum DC reverse voltage of 75 V and an average rectified forward current of 150 mA. The device exhibits a maximum forward voltage of 1 V at 50 mA and a reverse leakage current of 2 µA at 75 V. Key electrical characteristics include a reverse recovery time of 4 ns, junction capacitance of 4 pF at 0 V and 1 MHz, and a maximum operating junction temperature of 125°C. It is housed in a compact 0402 (SOD-923F) surface-mount package.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards
• High-speed switching capability with 4 ns reverse recovery time
• Compact surface-mount footprint for dense PCB layouts

Applications

• Automotive electronic circuits requiring AEC-Q101 compliance
• General-purpose signal switching applications
