Key electrical parameters include a peak reverse voltage of 75 V, an average forward current of 200 mA, and a maximum surge current of 2 A. The device exhibits a fast recovery time of 20 ns with a forward voltage of 1.2 V and a reverse current of 500 nA. It operates within a temperature range of -65 °C to +175 °C.

Single Diodes Feature Summary

• Fast switching capability optimized for computer and signal processing circuits
• High thermal stability supporting operation up to 175 °C junction temperature
• Robust construction with a 2 A peak surge current rating

Single Diodes Applications

• Signal or computer diode circuits
• General-purpose switching applications
• High-speed rectification tasks

Single Diodes Procurement Notes

Verify the specific ordering suffix '-1' against the official Microchip datasheet to confirm the exact packaging format and reel specifications. Ensure compliance with RoHS directives as indicated by the 'E3' suffix. Confirm that the DO-35-2 through-hole package aligns with the target PCB design requirements before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a through-hole solution is required for high-speed switching rather than surface-mount alternatives like the CDLL4148e3. The 75 V reverse voltage rating suits low-voltage logic interfaces. Consider the 20 ns recovery time for frequency constraints. Verify that the 200 mA continuous current rating meets the circuit load demands without exceeding thermal limits.
