Littelfuse P4SMA6.8A

The P4SMA series is designed specifcally to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

• 400W peak pulse power capability at 10/1000µs waveform, repetition rate (duty cycles): 0.01%
• Excellent clamping capability
• Low incremental surge resistance
• Typical |R 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 BV min
• High temperature to reflow soldering guaranteed: 260°C/40sec
• pBR@TJ = VBR@25°C × (1+αT×(TJ - 25)) (αT: Temperature Coefficient, typical value is 0.1%)
• UL Recognized epoxy meeting flammability classification V-0
• Meet MSL level1, per J-STD-020, LF maximum 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-STD609A.01)

• TVS devices are ideal for the protection of I/O Interfaces, VCC bus and other vulnerable circuits used in Telecom, Computer, Industrial and Consumer electronic applications.
