Zener Transient
Voltage Suppressor
SOD−123 Flat Lead Package
The 1SMF16B is designed to protect voltage sensitive components
from high voltage, high energy transients. Excellent clamping
capability, high surge capability, low Zener impedance and fast
response time. Because of its small size, it is ideal for use in cellular
phones, portable devices, business machines, power supplies and
many other industrial/consumer applications.
