A1N4148WS-HF

Overview

The A1N4148WS-HF is a small signal switching diode manufactured by Comchip Technology, designed for high-speed applications. It features a single configuration in an SOD-323-2 surface-mount package. Key electrical parameters include a peak reverse voltage of 75 V and a maximum forward current of 150 mA. The device exhibits a fast recovery time of 4 ns with a maximum diode capacitance of 2 pF. Power dissipation is rated at 200 mW, while the forward voltage is specified at 1.25 V and reverse current at 1 uA. Operating temperatures range from -65 C to +150 C.

Feature Summary

High-speed switching capability with 4 ns recovery time
Automotive-grade reliability certification
Compact SMD/SMT footprint for space-constrained designs

Applications

Automotive electronic circuits
High-speed signal switching
Computer peripheral interfaces

Procurement Notes

Verify the specific automotive qualification status against the manufacturer's official datasheet before integration into safety-critical systems. Confirm that the 75 V peak reverse voltage rating aligns with the target circuit's operational requirements. Ensure compatibility with the SOD-323-2 package dimensions during PCB layout. Cross-reference RoHS compliance documentation to meet environmental regulations.

Selection Notes

Select this component when a compact, high-speed switching diode with automotive certification is required. Compare the 75 V reverse voltage limit against standard 100 V variants if higher surge tolerance is needed. Evaluate the 200 mW power dissipation against thermal constraints in dense assemblies. Consider the 4 ns recovery speed for high-frequency signal processing tasks.

Part Context

This part belongs to Comchip Technology's small signal switching diode portfolio, specifically tailored for automotive and general-purpose electronics. It serves as a surface-mount alternative to through-hole variants like the 1N4148-1, offering similar switching characteristics in a smaller form factor. The 'A' prefix typically denotes automotive-grade qualification within the manufacturer's lineup.
