Non-repetitive current pulse , per Fig. 4 and derated above TJ (initial) =25OC per Fig. 3. 2. Mounted on copper pad area of 0.2x0.2” (5.0 x 5.0mm) to each terminal. 3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional device only, duty cycle=4 per minute maximum. 4. VF < 3.5V for single die parts and VF< 5.0V for stacked-die parts. 5. For stacked die component details, please refer to part numbers labeled by * in Electrical Characteristics. Description The P6SMB series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. Features • 600W peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycles):0.01% • Excellent clamping capability • Low incremental surge resistance • Typical IR less than 1μA when VBR min>12V • Optimized surface mount footprint for minimal PCB space impact • Low profile package • Typical failure mode due to exceeding maximum ratings is a short circuit condition • Whisker test conducted based on Table 4a and 4c of JEDEC JESD201A • IEC 61000-4-2 ESD 30kV(Air), 30kV (Contact) • EFT protection of data lines in accordance with IEC 61000-4-4 • Built-in strain relief • Fast response time: typically less than 1.0ps from 0V to VBR min • High temperature to reflow soldering guaranteed: 260°C/30sec • VBR @ TJ= VBR@25°C x (1+αT x (TJ - 25)) (αT:Temperature Coefficient, typical value is 0.1%) • UL Recognized compound meeting flammability classification V-0 • Meet MSL level1, per J-STD-020, LF maximun peak of 260°C • Matte tin lead–free plated • Halogen free and RoHS compliant • Pb-free E3 means 2ND level interconnect is Pb-free and the terminal finish material is tin(Sn) (IPC/ JEDEC J-STD-609A.01) • UL Recognized to ANSI/UL 497B: Protectors for Data Communications and FireAlarm Circuits. Applications TVS devices are ideal for the protection of I/O Interfaces, VCC bus and other vulnerable circuits used in Telecom, Computer,.
