SMCJ78A / CA 数据手册

SMCJ Series

Transient Voltage Suppressors

PINNING

Stand-off Voltage : 5 to 440 V

Peak Pulse Power : 1500 W

DESCRIPTION

Cathode

Features

Anode

• 1500 W peak pulse power capability on 10 /1000 µs

• Excellent clamping capability

• Fast response time: typically less than 1 ps from

0 V to V_(BR)for unidirectional and 5 ns for

bidirectional types

Mechanical Data

• Case: SMC (DO-214AB) molded plastic

• Epoxy: UL 94V-0 rate flame retardant

• Terminals: Solder plated

Plastic Package : SMC(DO214AB)

• Polarity: Color band denotes cathode end

Types for Bidirectional Applications

• For bidirectional use CA suffix for types SMCJ5.0A thru types SMCJ440A (e.g. SMCJ5.0CA, SMCJ440CA)

• 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%.
