Product Attributes

Introduction

The SMAJ series is designed specifcally to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.

Features

• 400W Peak pulse power capability at 10/1000μs waveform, repetition rate (duty cycle): 0.01 %
• Excellent clamping capability
• Typical |R less than 1μΔ when VBR min>12V
• For surface mounted applications to optimize board space
• Low profle package
• Typical failure mode is short from over-specifed voltage or current
• Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c
• IEC-61000-4-2 ESD 30kV(Air), 30kV (Contact)
• ESD protection of data lines in accordance with IEC 61000-4-2
• EFT protection of data lines in accordance with IEC 61000-4-4
• Built-in strain relief
• Fast response time: typically less than 1.0ρs from 0 Volts to VBR min
• Glass passivated junction
• Low inductance
• High temperature to refow soldering guaranteed: 260°C/30sec
• V @ T = V @25°C x (1+αT x (T - 25)) (αT:Temperature Coeffcient, typical value is 0.1 %)
• Plastic package is fammability rated V-0 per Underwriters Laboratories
• Meet MSL level1, per J-STD-020, LF maximun peak of 260°C
• Matte tin lead–free Plated
• Halogen free and RoHS compliant
• Pb-free E3 means 2nd level interconnect is Pb-free and the terminal fnish material is tin(Sn) (IPC/JEDEC J-STD609A.01)

Applications

• TVS devices are ideal for the protection of I/O Interfaces, VCC bus and other vulnerable circuits used in Telecom, Computer, Industrial and Consumer electronic applications.
