As marked, No suffix indicates Common Cathode,
suffix"A" indicates Common Anode
Mounting Position:
(Ratings at 25 C ambient temperature unless otherwise specified ,Single phase ,half wave ,resistive or inductive
load. For capacitive load,derate by 20%.)
Dimensions in inches and (millimeters)
Plastic package has Underwriters Laboratory Flammability Classification 94V-0
Metal silicon junction ,majority carrier conduction
Guard ring for over voltage protection
Low power loss ,high efficiency
High current capability ,Low forward voltage drop

free wheeling ,and polarity protection applications
Dual rectifier construction
High temperature soldering guaranteed:250 C/10 seconds,
0.17"(4.3mm)from case
Notes:
1.Pulse test: 300 s pulse width,1% duty cycle
2.Thermal resistance from junction to case
