Notes: 1. Non-repetitive current pulse, per Fig. 4 and derated above TJ (initial) =25OC per Fig. 3. 2. Mounted on copper pad area of 0.2x0.2” (5.0 x 5.0mm) to each terminal. 3. Measured on 8.3ms single half sine wave or equivalent square wave for unidirectional
component only, duty cycle=4 per minute maximum.
Description
The 1.5SMB Series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.
Features & Benefits
■ For surface mounted applications to optimize board space
■ Low profile package
■ Typical failure mode is short from over-specified voltage or current
■ VBR @ TJ= VBR@25°C x (1+αT x (TJ - 25))(αT:Temperature Coefficient, typical value ...
