Description

The 5.0SMDJ series is designed specifically to protect sensitive electronic

equipment from voltage transients induced by lightning and other transient

voltage events.

Features

For surface mounted applications in order to optimize board space

Low leakage

Uni and Bidirectional unit

Glass passivated junction

Low inductance

Excellent clamping capability

5000W Peak power capability at 10 × 1000µs waveform Repetition

rate (duty cycle):0.01%

Functional Diagram

Fast response time: typically less than 1.0ps from 0 Volts to V_BRmin

Typical I_Rless than 5μA above 25V.

High Temperature soldering: 260°C/40 seconds at terminals

Typical maximum temperature coefficient ΔV_BR= 0.1% ×

V_BR@25°C× ΔT

Bi-directional

Cathode

Anode

Plastic package has Underwriters Laboratory Flammability 94V-0

Matte tin lead–free Plated

Uni-direction

Halogen free and RoHS compliant

Typical failure mode is short from over-specified voltage or current

Whisker test is conducted based on JEDEC JESD201A per its table

4a and 4c

Applications

IEC-61000-4-2 ESD 15kV(Air), 8kV (Contact)

ESD protection of data lines in accordance with IEC 61000-4-2
