SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR

Stand-off Voltage

Peak Pulse Power

5.0 to 170 Volts

600 Watts

SMB5.0 THRU SMB170CA

FEATURES

Plastic package has Underwriters Laboratory

Flammability Classification 94V-O

DO-214AA(SMB)

For surface mounted applications in order to optimize

board space

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

V (BR) for unidirectional and 5.0ns for bidirectional types

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

High temperature soldering guaranteed:

250℃/10 seconds at terminals

Dimensions in inches and (millimeters)

MECHANICAL DATA

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

DEVICES FOR BIDRECTIONAL APPLICATIONS

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

.Electrical Characteristics apply in both directions.

Notes:

1. Non-repetitive current pulse, per Fig.3 and derated above TA=25℃ per Fig.2

2. Mounted on 0.2×0.2” (5.0×5.0mm) copper pads to each terminal

3. Measured on 8.3ms single half sine-wave or equivalent square wave duty cycle = 4 pulses per minutes maximum.

4. VF=3.5 V on SMB thru SMB-90 devices and VF=5.0V on SMB-100 thru SMB-170 devices
