Features, Applications 
5000W Unidirectional and Bidirectional Load Dump Glass Passivated Automotive T.V.S. Developped to suppress transient in the automotive system, protecting mobile transceivers, radios and tape decks from overvoltages (width pulses). Mounting instructions 1. Min. distance from body to soldering point, 4 mm. 2. Max. solder temperature, 350 °C. 3. Max. soldering time, 3.5 sec. 4. Do not bend lead at a point closer than 4 mm. to the body. Glass passivated junction Low Capacitance AC signal protection Response time typically < 1 ns. Molded case The plastic material carries U/L recognition 94 V0 Terminal: Axial leads Ppp PM(AV) IFSM Tj Tstg Peak pulse power with 10/1000 µs exponential pulse Steady State Power Dissipation 75 ºC Mounted in copper leaf area 20 mm2 Non repetitive surge peak forward current = 10 msec.) (Note 1) Operating temperature range Storage temperature range 175 °C NOTES: 1 VBR measured after IT= Square Wave Pulse or equivalent. 2. Surge Current waveform per Figure (Pulse Waveform) and Derate per Figure (Pulse Derating Curve).
