1N4148W-HF

Single Diodes Overview

The Comchip Technology 1N4148WT-HF is a small signal switching diode housed in an SOD-523-2 surface-mount package. It features a peak reverse voltage of 100 V and supports a maximum forward current of 150 mA with a power dissipation rating of 150 mW. The device exhibits a fast recovery time of 4 ns, a forward voltage of 1.25 V at rated current, and a low reverse leakage current of 1 uA. Operating temperatures range from -55 C to +150 C, ensuring reliability across diverse environmental conditions.

Single Diodes Feature Summary

• Fast switching capability with a 4 ns recovery time for high-speed signal processing
• Compact SMD/SMT form factor suitable for space-constrained circuit designs
• Wide thermal operating range extending up to +150 C junction temperature

Single Diodes Applications

• High-speed electronic switching circuits
• Signal rectification in consumer electronics
• Protection against voltage spikes in sensitive components

Single Diodes Procurement Notes

Verify the specific suffix 'WT' to confirm the SOD-523-2 package variant, as standard 1N4148 parts often utilize different packages like DO-35 or SOD-123. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference the manufacturer's datasheet for precise handling and soldering profiles to maintain component integrity during assembly processes.

Single Diodes Selection Notes

Select this component when a compact surface-mount switching diode with 100 V blocking capability is required. The 150 mA continuous current rating suits general-purpose applications, while the 4 ns recovery speed addresses high-frequency needs. Consider the SOD-523-2 footprint constraints and verify that the 150 mW power dissipation aligns with your thermal management strategy.

Single Diodes Part Context

This part belongs to the widely recognized 1N4148 family of silicon switching diodes. While traditional versions use axial leaded packages, the WT-HF designation indicates a modern surface-mount adaptation by Comchip Technology. This evolution allows for automated assembly and denser PCB layouts compared to legacy through-hole implementations.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4148 variants in SOD-523 packages, such as those from Diodes Inc. or Nexperia. Verify electrical equivalence regarding the 100 V reverse voltage and 150 mA forward current ratings before integration.
