BZX55-y91

BZX55 Series Zener Diodes Zener Voltage Range: 0.8, 2.4 to 200 Volts Power Dissipation: 500mW Features Silicon Planar Power Zener Diodes. The Zener voltages are graded according to the international E 24 standard. Standard Zener voltage tolerance is ±5%. Replace suffix "C" with "B" for ±2% tolerance. Other voltage tolerances and other Zener voltages are available upon request.
