The SMF series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. SMF package is 50% smaller in footprint when compare to SMA package and delivering one of the lowest height profiles (1.1mm) in the industry.
Compatible with industrial standard package SOD-123
Low profile: maximum height of 1.1mm
For surface mounted applications to optimize board space
Typical failure mode is short from over-specified voltage or current
200W peak pulse power capability at 10x1000μs waveform, repetition rate (duty cycle):0.01%
Low inductance, excellent clamping capability
Fast response time:typically less than 1.0ns from 0 Volts to VBR min
Built-in strain relief
Glass passivated junction
High temperature soldering: 260°C/40 seconds at terminals
Matte tin lead–free plated
Halogen free
