Features and Benefits
▪ DC blocking voltage, VDC, 22 to 32 V
▪ Low VF (0.95 to 1.0 V max, at IF = 6 A)
▪ Low reverse leakage current, IR = 10 μA
▪ High temperature range
▪ Flammability: UL94V-0 (Equivalent)
Applications
▪ High peak power
▪ High-temperature
▪ Clamping diode
▪ General use Zener diode
Package: Surface Mount SZ-10
SZ-10 Series
Power Zener Diodes
Description
The SZ-10 series are 22 V and 32 V Zener diodes capable
of withstanding high peak power surges. The resin case and
substantial mounting surfaces allow substantial heat dissipation,
and operating temperatures up to TJ = 175°C, facilitating heat-
dissipation design.
