Abstract
En elektrisk barriere for kobling av en strømforsyning til elektrisk utstyr som blir brukt i potensielle eksplosive områder. Barrieren inkluderer en shuntzenerdiode (14) for å begrense utgangsspenningen og en seriemotstand (16) for å begrense strømmen. I anordningen som er vist er shuntzenerdioden (14) en silikonkarbidzenerdiode som har en høyere toleranse for store utgangsstrømmer og/eller operasjonstemperatur enn zenerdioder som er fremstilt kommersielt.
