Product details

500W Zener TVS in a Hermetic SQ-MELF

The 5.7V reverse standoff voltage and 7.13V minimum breakdown voltage define the clamping threshold; the maximum clamping voltage at 44.6A peak pulse current is 11.2V.

SQ-MELF Package and Mounting Considerations

Housed in a SQ-MELF, B (surface-mount) package — a hermetic ceramic body with metallized end caps. The B suffix indicates the bidirectional configuration. This package is common in high-reliability and space-grade designs because the hermetic seal prevents moisture ingress and the end-cap solder joints tolerate thermal cycling better than a plastic SMD. The mounting surface must be flat and the solder profile matched to the end-cap metallization — typically a 60/40 or SAC305 reflow with a peak temperature around 245°C.

The base product number is 1N6103.

Frequently asked questions

Is the 1N6103AUS a bidirectional or unidirectional diode?

It is a single bidirectional channel — the B in the package suffix (SQ-MELF, B) confirms the bidirectional configuration. The part clamps both positive and negative transients symmetrically.
