TECHNICAL DATA
5 Watt Surmetic 40
Silicon Zener Diodes
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 is in an axial-lead, transfer-molded plastic package that offers protection in all com-
mon environmental conditions.
Specification Features:
•
Up to 180 Watt Surge Rating @ 8.3 ms
•
Maximum Limits Guaranteed on Seven Electrical Parameters
Mechanical Characteristics:
CASE:
