SMF5.0AT1 Series Zener Transient Voltage Suppressor SOD-123 Flat Lead Package
The SMF5.0A Series 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.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. Non-repetitive current pulse at TA = 25C, per waveform of Figure 2. 2. Non-repetitive current pulse at TA = 25C, per waveform of Figure 3. 3. Mounted with recommended minimum pad size, DC board FR-4.
