1N53 Series
5 Watt Surmetict
40 Zener Voltage Regulators
This is a complete series of 5 Watt Zener diodes with tight limits and
better operating characteristics that reflect the superior capabilities of
silicon−oxide passivated junctions. All this in an axial lead,
transfer−molded plastic package that offers protection in all common
environmental conditions.

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
1. Max operating temperature for DC conditions is 150°C, but not to exceed
200°C for pulsed conditions with low duty cycle or non−repetitive.
