SZ1SMB28AT3G General Description

The SZ1SMB series is designed to protect voltage sensitive components from high voltage, high energy transients. They have excellent clamping and high surge capability, as well as fast response time. The SZ1SMB 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.

Key Features

Zener Transient Overvoltage Suppressors
Working Peak Reverse Voltage Range − 5.0 V to 170 V for uni-directional, and 10 V to 75 V for bi-directional
Standard Avalanche Breakdown Voltage Range −6.4 V to 209 V for uni-directional, 11.1 V to 92.07 V for bi-directional
Peak Power − 600 W @ 1.0 ms
ESD Rating of Class 3 (> 16 kV) per Human Body Model
Maximum Clamp Voltage @ Peak Pulse Current
Low Leakage < 5.0 μA Above 10 V
Intended for UL 497B Type Protection
Response Time is Typically < 1.0 ns
Pb-free means 2nd level interconnect is Pb-free and the terminal finish material is tin(Sn) (IPC/JEDEC J-STD-609A.01)
