The BZV55 series Zener diodes are silicon planar power Zener diodes for use as low voltage stabilizer or voltage reference. The Zener voltages are graded according to the international E 24 standard. Higher Zener voltages and 1% tolerance available on request. Diodes available in these tolerance series: ±2% BZV55-B, ±3% BZV55-F, ±5% BZV55-C.
