. . . a complete series of 1 to 3 Watt Zener Diodes with limits and operating characteristics
that reflect the superior capabilities of silicon-oxide-passivated junctions. All this in an
axial-lead, transfer-molded plastic package offering protection in all common environmental conditions.
Specification Features:
• Surge Rating of 98 Watts @ 1 ms
• Maximum Limits Guaranteed On Up To Six Electrical Parameters
• Package No Larger Than the Conventional 1 Watt Package
Mechanical Characteristics:
CASE: Void-free, transfer-molded, thermosetting plastic
FINISH: All external surfaces are corrosion resistant and leads are readily solderable
POLARITY: Cathode indicated by color band. When operated in zener mode, cathode
will be positive with respect to anode
MOUNTING POSITION: Any
WEIGHT: 0.4 gram (approx)
