Product details

Active Zener TVS – 1500W surge protection in SQ-MELF

It clamps at 64.6V max with a 23.2A peak pulse current, making it a fit for protecting 35.8V nominal rails in industrial and telecom equipment.

Breakdown voltage and clamping performance

Minimum breakdown voltage is 44.7V, with a reverse standoff of 35.8V. The clamping voltage at rated peak pulse current is 64.6V max – this margin defines the protection window for downstream components.

SQ-MELF package and Tape & Reel supply

Housed in a SQ-MELF, C case – a surface-mount, cylindrical body with solderable end caps.
