• Epoxy: UL 94V-0 rate flame retardant

• Terminals: Solder plated

Top view

Plastic Package : SMC(DO-214AB)

• Polarity: Color band denotes cathode end

Types for Bidirectional Applications

• For bidirectional use CA suffix for types SMDJ5.0A thru types SMDJ440A (e.g. SMDJ5.0A, SMDJ440CA)

• Electrical characteristics apply in both directions

Maximum Ratings and Electrical Characteristics

Ratings at 25℃ ambient temperature unless otherwise specified. Single phase, half wave, 50 Hz, resistive or inductive load.

For capacitive load, derate by 20%
