1SMA10CAT3/D
1SMA10CAT3 Series
400 Watt Peak Power Zener
Transient Voltage
Suppressors
Bidirectional*
The SMA series is designed to protect voltage sensitive
components from high voltage, high energy transients. They have
excellent clamping capability, high surge capability, low zener
impedance and fast response time. The SMA series is supplied in
ON Semiconductor's exclusive, cost-effective, highly reliable
Surmetic
TM

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not im-
plied, damage may occur and reliability may be affected.
