Notes:
1. Transient surge ratings are provided for reference only and may not represent surge
withstand capability in the end application. Factors including, but not limited to, series
impedance, mounting, and wiring may affect surge withstand capability.
2. In accordance with IEC 60060-1, front time = 8µs and time to half-value = 20µs
