SZ1SMA Series - Automotive and High Reliability TVS from TVS Diodes

SZ1SMA Series - 400W in SMA Package

The SZ1SMA 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 SZ1SMA series is supplied in the Littelfuse exclusive, cost-effective, highly reliable package and is ideally suited for use in communication systems, automotive, numerical controls, process controls, medical equipment, business machines, power supplies and many other industrial and consumer applications.

Features:

Zener Transient Overvoltage Suppressors
Peak Power − 400 W @ 1ms
ESD Rating of Class 3 (>16 kV) per Human Body Model
Response Time is Typically < 1 ns
Flat Handling Surface for Accurate Placement
Package Design for Top Slide or Bottom Circuit Board Mounting
Low Profile Package
Pb-free means 2nd level interconnect is Pb-free and the terminal finish material is tin(Sn) (IPC/JEDEC J-STD-609A.01)
SZ Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q101 Qualified and PPAP Capable
