ZENER DIODES
POWER DISSIPATION: 500 mW
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%,
Replace suffix "C" with "A" for 1%.
other voltage tolerance and other zener voltage are
available upon request.
