GALAXY ELECTRICAL

SMAJ5.0 - - - SMAJ188CA

BREAKDOWN VOLTAGE: 5.0 --- 188 V

PEAK PULSE POWER: 400 W

TRANSIENT VOLTAGE SUPPRESSOR

FEATURES

Plastic package has underwriters laboratory

flammability classification 94V-0

Optimized for LAN protection applications

Low profile package with built-in strain relief for

surface mounted applications

DO-214AC(SMA)

Glass passivated junction

Low incremental surge resistance, excellent clamping

capability

400W peak pulse power capability with a 10/1000µs wave-

form, repetition rate (duty cycle): 0.01% (300W above 78V)

Very fast response time

High temperature soldering guaranteed: 250°C/10

seconds at terminals

MECHANICAL DATA

Case:JEDEC DO-214AC molded plastic over passivated

chip

Terminals: solder plated, solderable per MIL-STD-750,

method 2026

Polarity: foruni-directional types the color band denotes

the cathode, which is postitive with respect to the

anode under normal TVS operation

Mounting position: any Weight: 0.002 ounces, 0.064 grams

Devices for Bidirectional Applications

For bi-directional devices, use suffixC or CA (e.g. SMAJ10C, SMAJ10CA). Electrical characteristics applyin both directions.

MAXIMUM RATINGS AND CHARACTERISTICS

Ratings at 25 ambient temperature unless otherwise specified.
