FEATURES

MECHANICAL DATA

MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS

Notes:

DEVICES FOR BIDRECTIONAL APPLICATIONS

Peak Pulse power dissipation with a 10/1000μs waveform(NOTE1,2,FIG.1)

Peak Pulse current with a 10/1000μs waveform (NOTE1,FIG.3)

Peak forward surge current, 8.3ms single half sine-wave superimposed

Maximum instantaneous forward voltage at 50A (NOTE 3,4)

unidirectional only (NOTE 3)

Operating Junction and Storage Temperature Range

on rated load (JEDEC Method) (Note2,3) – unidirectional only

.Electrical Characteristics apply in both directions.

board space

Plastic package has Underwriters Laboratory

Flammability Classification 94V-O

For surface mounted applications in order to optimize

Low profile package

Built-in strain relief

Glass passivated junction

Low incremental surge resistance

600W peak pulse power capability with a 10/1000μs

Waveform, repetition rate (duty cycle): 0.01%

Excellent clamping capability

Fast response time: typically less than 1.0ps from 0 Volts to

For devices with V

High temperature soldering guaranteed:

250℃/10 seconds at terminals

Cass: JEDEC DO-214AA,molded plastic body over passivated junction

Terminals: Axial leads, solderable per MIL-STD-750, Method 2026

Polarity: Color bands denotes positive end (cathode) except bidirectional

Mounting position: any

Weight: 0.003 ounces, 0.093 gram

For bidirectional use C or CA suffix for types SMB-5.0 thru SMB-170 (e.g. SMBG5.0C,SMBJ170CA)

Ratings at 25℃ ambient temperature unless otherwise specified
