1SMA5.0AT3G Series
Description
The 1SMA5.0AT3G 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 1SMA5.0AT3G 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/consumer applications.

6. A transient suppressor is normally selected according to the working peak reverse voltage (VRWM), which should be equal to or greater than the DC or continuous peak operating voltage level.
7. V BR measured at pulse test current IT at an ambient temperature of 25°C.
8. Surge current waveform per Figure 2 and derate per Figure 3.
9. Bias voltage = 0 V, F = 1.0 MHz, TJ = 25°C.
