ZENER DIODES
Units are available with anode-
to-case and cathode-to-case
connections (standard and
reverse polarity). For reverse
polarity add suffix “R” to type
number.
MAXIMUM RATINGS:
Junction and Storage
Temperature: -65°C to +175°C
DC Power Dissipation: 50 Watts
(Derate 0.5W/°C above 75°C)
TOLERANCE DESIGNATION:
Standard voltage tolerances are
+/-5% with B suffix, +/-10%
with an A suffix and +/-20%
with no suffix.
• Standard polarity is anode-to-case
• Reverse polarity with cathode-to-case by designation R suffix in part number, e.g. 1N3305RB, etc.
