Production specification

Transient Voltage Suppressor

SMAJ5.0--SMAJ440CA

Features



Optimized for LAN protection applications



Low profile package with built-in strain relief

for surface mounted applications



Low incremental surge resistance, excellent clamping capability

400W peak pulse power capability with a 10/1000¦Ìs 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: SMA molded plastic

Molding compound, UL flammability classification rating 94V-0

Terminals: Solder plated, solderable per MIL- STD-202,Method 208

Polarity: Color band denotes cathode end

Devices for Bidirectional Applications



For bi-directional devices, use suffix C or CA (e.g. SMAJ10C, SMAJ10CA). Electrical

characteristics apply in both directions.
