• Engineered for high surge current capability and operational efficiency

Single Diodes Applications

• High-speed switching circuits
• General-purpose rectification in compact electronics
• Signal processing applications requiring low capacitance

Single Diodes Procurement Notes

Verify the specific suffix 'RRG' against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and exact binning requirements. Ensure that the SOD-323 footprint matches your PCB design constraints. Cross-reference the 100V and 150A ratings with your circuit's peak inverse voltage and forward current demands to prevent component failure under stress conditions.

Single Diodes Selection Notes

Select this component when a standard small-signal diode is insufficient for high-frequency operations requiring sub-5ns recovery times. The SOD-323 form factor makes it suitable for dense consumer electronics or telecommunications equipment where space is limited. Consider the 2pF capacitance limit for high-impedance signal paths to minimize signal distortion during switching transitions.

Single Diodes Part Context

This part belongs to the 1N4148 family of switching diodes, adapted for surface-mount technology. While traditional through-hole variants exist, the WSH designation indicates a specific surface-mount configuration optimized for automated assembly. Taiwan Semiconductor produces this variant to meet industry standards for reliability and performance in general-purpose electronic devices.

Single Diodes Replacement Considerations

Direct substitutes include other SOD-323 packaged 1N4148 variants from manufacturers such as ON Semiconductor (e.g., 1N4148WS) or Vishay, provided they match the 100V reverse voltage and 4ns reverse recovery time specifications. Verify pinout compatibility and thermal dissipation capabilities before substitution.
