1N4370A Series
500 mW DO-35 Hermetically
Sealed Glass Zener Voltage
Regulators
This is a complete series of 500 mW Zener diodes with limits and
excellent operating characteristics that reflect the superior capabilities
of silicon–oxide passivated junctions. All this in an axial–lead
hermetically sealed glass package that offers protection in all common
environmental conditions.
