Product Attributes

Introduction

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

Features

• Low incremental surge resistance
• Typical |R less than 2μA when VBR min>12V
• High temperature to refow soldering guaranteed: 260°C/30sec
• VBA @T,1Π = VBA @25°C×(1 + αT ×(TJ - 25)) (αT:Temperature Coeffcient, typical value is 0.1% )
• UL Recognized compound meeting fammability rating V - 0
• 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 finish material is tin(Sn) (IPC/JEDEC J - STD609A.01)
• 3000W P PPM capability at 10/1000μs waveform, repetition rate (duty cycles):0.01%
• For surface mounted applications in order to optimize board space
• Low profile package
• Typical failure mode is short from over - specifed voltage o 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
