NOTES:1. VBR measured after IT applied for 300µs. IT= Square Wave Pulse or equivalent.
2. For Bidirectional use “C” or “CA” Suffix for all types (e.g.: P4KE6.8C, P4KE6.8CA, P4KE440C, P4KE440CA).
Electrical characteristics apply in both directions.
3. For bidirectional types having VRWM of 10 volts and less, the ID limit is doubled.
