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.
