Notes:
(1) The 1.0 amp rating @ 55°C requires no heat sinking, special mounting, or forced air across the body of the
device.
(2) Recovery conditions: 0.5 Amp forward current to -1.0 Amp reverse current. Recovery time measured when
rectifier recovers to -.25 Amp.
Storage temperature: -65°C to +175°C.
