SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR

Breakdown Voltage

Peak Pulse Power

6.8 to 200 Volts

400 Watts

SM6.8 THRU SM200CA

FEATURES

DO-213AB

Plastic package has Underwriters Laboratory

Flammability Classification 94V-O

For surface mounted applications

Glass passivated junction

Low inductance surge resistance

Fast response time: typical less than 1.0ps

from 0 volts to V(BR) for unidirectional AND 5.0ns for

bidirectional types

400W peak pulse capability with a 10/1000μs waveform,

repetition rate (duty cycle): 0.01%

For devices with V(BR) ≥10V, ID are typically less than 1.0μA

High temperature soldering guaranteed:

250℃/10 seconds at terminals

Dimensions in inches and (millimeters)

MECHANICAL DATA

Cass: JEDEC DO-213AB,molded plastic body over passivated junction

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

Polarity: Blue bands denotes positive end (cathode) for unidirectional and yellow band in the

Middle for bidirectional types

Mounting position: any

Weight: 0.116 ounces, 0.0064 gram

DEVICES FOR BIDRECTIONAL APPLICATIONS

For bidirectional applications use suffix letters C or CA for types SM6.8 thru SM200A (e.g. SM6.8C,

SM200CA).Electrical Characteristics apply in both directions.
