SZSMF33AT1G ON Semiconductor

TVS Diodes Surface Mount > 200W > SZSMF Series RoHS Pb e3 SZSMF Series Description Uni-Directional The SZSMF 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 Standoff Voltage: 5 58 Volts Peak Power: 200 Watts 1 ms Low Leakage Agency Approvals Response Time is Typically < 1 ns AGENCY AGENCY FILE NUMBER ESD Rating of Class 3 (> 16 kV) per Human Body Model E128662 ESD Rating of Level 4 (8 kV Contact Discharge) per IEC 61000-4-2 EFT (Electrical Fast Transients) Rating of 40 A Maximum Ratings and Thermal Characteristics per IEC 61000-4-4 Rating Symbol Value Unit Low Profile: Maximum Height of 1.0 mm Maximum Ppk Dissipation (PW10/1000 s) P 200 W Small Footprint: Footprint Area of 8.45 mm2 PK (Note 1) Supplied in 8 mm Tape and Reel 3,000 Units per Reel Maximum P Dissipation T = 25C, PK A P 1000 W PK (PW8/20 s) (Note 2) Cathode Indicated by Polarity Band DC Power Dissipation T = 25C P A D mW 385 Lead Orientation in Tape: Cathode Lead to Sprocket Holes (Note 3) Derate Above 25C 4.0 mW/C These components are PbFree and are RoHS Compliant R Thermal Resistance from Junctionto JA 325 C/W Ambient (Note 3) SZ Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements Thermal Resistance, Junction-to-Lead (Note3) R 26 C/W JL AECQ101 Qualified and PPAP Capable 55 to Operating and Storage Temperature Range T T C J, stg +150 Functional Diagram Bi-directional Stresses exceeding Maximum Ratings may damage the component. 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 may affect component reliability. Cathode Anode 1. Nonrepetitive current pulse at T = 25C, per waveform of Figure 2.
