Scrs Procurement Notes

Verify the specific voltage suffix required for the application, as the 2N691 series spans multiple voltage ratings. Confirm package compatibility and lead-free status if RoHS compliance is mandatory. Cross-reference datasheets from authorized distributors to ensure the exact variant matches the design specifications before procurement.

Scrs Selection Notes

Select the appropriate voltage rating within the 25V to 800V range based on peak inverse voltage requirements. Ensure the thermal management system can handle the power dissipation associated with 25A RMS operation. Verify that the gate trigger characteristics align with the driving circuit capabilities for reliable turn-on performance.
