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 ...
