TRANSIL
FEATURES PEAK PULSE POWER= 400 W @ 1ms. BREAKDOWN
VOLTAGE RANGE : From 6V8 to 220 V. UNI AND BIDIRECTIONAL TYPES. LOW CLAMPING FACTOR. FAST RESPONSE TIME: Tclamping : 1ps (0 V to VBR). JEDEC REGISTRED. SOD 6
(Plastic)
. . . . . .
DESCRIPTION Transil diodes provide high over
voltage protection by clamping action. Their instantaneous reponse to transients makes them praticularly suited to protect
voltage sensitive devices such as MOS Technology and low
voltage supplied IC’s.
