DESCRIPTION
The SMF series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.
FEATURES
- For surface mounted applications in order to optimize board space.
- Low profile package.
- Built-in strain relief.
- Glass passivated junction.
- Low inductance.
- Excellent clamping capability.
- Fast response time: typically less than 1.0ps from 0 Volts to VBR min for unidirectional types.
- Typical IR less than 1μA above 10V
- Plastic package has Underwriters Laboratory Flammability 94V-0.
