Product details

500W Zener TVS in a hermetic SQ-MELF

The SQ-MELF B package is a hermetic, surface-mount ceramic barrel — the same footprint used in MIL-spec and high-reliability designs where epoxy-molded parts risk moisture ingress or thermal cycling fatigue.

Clamping voltage and pulse current — the real protection numbers

At the peak pulse current of 42.37A, the clamping voltage holds at 11.76V max. That means a 5V rail sees the diode clamp at roughly double the nominal voltage during a surge — enough to keep downstream 5V-rated ICs inside their absolute-maximum ratings if the PCB layout keeps trace inductance low.

Active production — no obsolescence risk

The base product number is 1N6103, so variants with different screening levels or lead finishes share the same die.
