Littelfuse P4SMA250A

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 1μΔ when VBR min > 2V
• Optimized surface mount footprint for minimal PCB space impact
• Low profle 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 refow soldering guaranteed: 260°C/40sec @ T = V @25°C x (1+αT x (T - 25)) (αT:Temperature Coeffcient, typical value is 0.1% )
• UL Recognized epoxy meeting fammability classifcation 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 Pbfree and the terminal fnish material is tin(Sn) (IPC/ JEDEC J - STD - 609A.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.
