SMAJ Series

Transient Voltage Suppressors

PRODUCT SUMMARY

Stand-off Voltage ratings from 5.0V to 440V

Peak pulse power 400W in SMA surface-mount package

FEATURES

Plastic package has Underwriters Laboratory Flammability

Classification 94V-0

Optimized for LAN protection applications

Ideal for ESD protection of data lines in accordance with

IEC 1000-4-2 (IEC801-2)

Ideal for EFT protection of data lines in accordance with

IEC 1000-4-4 (IEC801-4)

Low profile package with built-in strain relief for surface-mount

Glass passivated junction

Low incremental surge resistance, excellent clamping capability

Peak pulse power capability of 400W with a 10/1000us waveform,

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

Very fast response time

High temperature soldering guaranteed:

260°C for 10 seconds at terminals

MECHANICAL DATA

Case: JEDEC DO-214AC (SMA) molded plastic over passivated chip

Terminals: Matte-Sn plated, solderable per MIL-STD-750,

Method 2026

Polarity: For uni-directional types the band denotes the cathode, which

is positive with respect to the anode under normal TVS operation.

Mounting position: Any

Weight: 0.002oz., 0.064g

Pb-free; RoHS-compliant

Devices for Bidirectional Applications

For bi-directional devices, use suffix CA (e.g. SMAJ10CA). Electrical characteristics apply in both directions.

MAXIMUM RATINGS
