Silicon Avalanche Diodes
400W Surface Mount Transient Voltage Supressors
RoHS P4SMA Series
FEATURES
• RoHS compliant
• For surface mounted applications in order to optimize
board space
• Low profile package
• Built-in strain relief
• Glass passivated junction
• Low Inductance
• Excellent clamping capability
• Repetition Rate (duty cycle):0.01%
• Fast response time: typically less than 1.0ps from 0 Volts to
V(BR) for unidirectional types
• Typical IR less than 1µA above 10V
• High temperature soldering: 250˚C/10 seconds at terminals
