Features:

• 400W peak pulse power capability
• Excellent clamping capability
• Low incremental surge resistance
• Fast response time:
typically less than 1.0ps from 0V to V_BR
for unidirectional and 5.0nS for bidirectional types.
• High temperature soldering guaranteed:
265oC/10S/9.5mm lead length at 5 lbs tension


Application

1. Suffix 'A' dnotes 5% tolerance device,no suffix 'A' dnotes 10% tolerance device.
2. For bidirectional use 'C' or 'CA' suffix for types P4KE7.5 thru types P4KE440A (e.g. P4KE7.5C,P4KE440CA), for unidirectional don't use 'C' suffix after types.
3. For bidirectional devices having VWM of 10 volts and less, the ID limit is doubled.
4. Electrical characteristics apply in both directions.
