MAXIMUM RATINGS AND ELECTRICAL CHARACTERISTICS

Notes:

GLASS PASSIVATED JUNCTION TRANSIENT VOLTAGE SUPPRESSORS

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

on rated load (JEDEC Method) (Notes 2,3) – unidirectional only

Maximum instantaneous forward voltage at 100A (NOTE3)

unidirectional only

Operating Junction and Storage Temperature Range

Plastic package has Underwriters Laboratory

For surface mounted applications in order to optimize

board space

Low profile package

Built-in strain relief

Glass passivated junction

Low inductance

1500W 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-214 AB, molded plastic over passivated junction

Terminals: Solder plated, solderable per MIL-STD-750, Method 2026

Polarity: For uni-direction types the Color band denotes the cathode, which is postitive with respect

Mounting Position: any

Weight: 0.007 ounces, 0.21 gram

For bidirectional use suffix C or CA for types SMC-5.0 thru SMC-170 (e.g. SMC5.0C, SMC170CA).

Electrical characteristics apply in both in both directions.
