TVS Diodes Surface Mount > 200W > SMF5.0AT1G Series Pb SMF5.0AT1G Series Description The SMF5.0AT1G 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. Features Standoff Voltage: 5 58 Volts Peak Power 200 Watts 1 ms (SMF5.0A SMF58A) Low Leakage Maximum Ratings and Thermal Characteristics Response Time is Typically < 1 ns ESD Rating of Class 3 (> 16 kV) per Human Body Model Rating Symbol Value Unit ESD Rating of Level 4 (8 kV Contact Discharge) per Maximum Ppk Dissipation (PW10/1000 P 200 W PK s) (Note 1) SMF5.0A SMF58A IEC6100042 EFT (Electrical Fast Transients) Rating of 40 A per Maximum Ppk Dissipation TA = 25C, P 1000 W PK (PW8/20 s) (Note 2) IEC6100044 Low Profile Maximum Height of 1.0 mm DC Power Dissipation T = 25C A mW 385 PD (Note 3) Small Footprint Footprint Area of 8.45 mm2 Derate Above 25C 4.0 mW/C Thermal Resistance from Junctionto R Supplied in 8 mm Tape and Reel 3,000 Units per Reel 8JA 325 C/W Ambient (Note 3) Cathode Indicated by Polarity Band Operating and Storage Temperature 55 to T T C Lead Orientation in Tape: Cathode Lead to Sprocket Holes J, stg Range Bi-directional +150 These Devices are PbFree and are RoHS Compliant Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions Functional Diagram may affect device reliability. 1. Nonrepetitive current pulse at TA = 25C, per waveform of Figure 2. 2.
