ꢀ 400W peak pulse power capability with a 10/1000us wave-

form, repetition rate (duty cycle): 0.01% (300W above 91V)

ꢀ Very Fast response time

ꢀ High temperature soldering guaranteed: 250^oC/10 seconds

at terminals

Mechanical Data

ꢀ Case: JEDEC DO-214AC molded plastic over passivated chip

ꢀ Terminals: Solder plated, solderable per MIL-STD-750,

Method 2026

ꢀ Polarity: For uni-directional types the band denotes the cathode,

which is positive with respect to the anode under normal TVS

operation

ꢀ Mounting Position: Any

ꢀ Weight: 0.002oz., 0.064g

Devices for Bidirectional Applications

For bi-directional devices, use suffix CA (e.g. P4SMA10CA). Electrical characteristics apply in both directions.
