P4SMA550A General Description

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

Key Features

400W peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycles): 0.01%
Excellent clamping capability
Typical IR less than 1μA when V
BR
min>12V
Surface mount footprint for compact PCB layout
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)
Built-in strain relief
Fast response time: typically less than 1.0ps from 0V to BV min

UL Recognized epoxy meeting flammability classification V-0 change to Plastic package is flammability rated V-0 per UL-94.
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-STD-609A.01)

Application

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.
