The SMF4L-T1G low leakage series is designed to protect sensitive systems or components from high voltage, high energy transients. It offers a fast response time, low Zener impedance, high surge and excellent clamping capabilities. Because of its small size, it is ideal for use in cellular phones, portable devices, business machines, power supplies and other industrial and consumer applications.

Features

Zener transient overvoltage suppressors
Working peak reverse voltage range 5 V to 78 V for unidirectional
Peak power: 400 watts &commat; 1 ms
Low leakage
Response time is typically < 1 ns
ESD rating of class 3 (> 16 kV) per human body model
IEC-61000-4-2 ESD 30 kV(Air), 30 kV (Contact)
EFT (Electrical Fast Transients) rating of 40 A per IEC 61000-4-4
Small footprint: footprint area of 8.45 mm<sup>2</sup>
Supplied in 8 mm tape and reel − 3,000 units per reel
Lead orientation in tape: cathode lead to sprocket holes
These components are Pb−free and are RoHS compliant

Applications

SMF4L-T1G low leakage Series is ideal for the protection of I/O interfaces, Vcc buses and other vulnerable circuit used in cellular phones, portable electronics, business machines, power supplies and other consumer applications. The low leakage is particularly well suited for battery operated electronics.
