x (TJ - 25))
(αT:Temperature Coefficient)
• Glass passivated chip
junction
• 1500W peak pulse power
capability at 10/1000μs
waveform, repetition rate

flammability rated V-0 per
Underwriters Laboratories
• 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)
Features
The TPSMC series is designed specifically to protect
sensitive electronic equipment from voltage transients
induced by lightning and other transient voltage events.
