Surface Mount Transient Voltage Suppressors (TVS)
SMDJ Series 5.0 To 440 V 3000W
Description
The SMDJ series is designed specifically to protect sensitive electronic
equipment from voltage transients induced by lightning and other transient
voltage events.
Features
u For surface mounted applications in order to optimize board space
u Low leakage
u Uni and Bidirectional unit
u Glass passivated junction
u Low inductance
u Excellent clamping capability
u 3000W Peak power capability at 10 × 1000µs waveform Repetition
rate (duty cycle):0.01%
u Fast response time: typically less than 1.0ps from 0 Volts to VBR min
u Typical IR less than 5μA above 12V.
u High Temperature soldering: 260°C/40 seconds at terminals
u Typical maximum temperature coefficient ΔVBR = 0.1% ×
VBR@25°C× ΔT
u Plastic package has Underwriters Laboratory Flammability 94V-0
u Matte tin lead–free Plated
u Halogen free and RoHS compliant
u Typical failure mode is short from over-specified voltage or current
u Whisker test is conducted based on JEDEC JESD201A per its table
4a and 4c
u IEC-61000-4-2 ESD 15kV(Air), 8kV (Contact)
u ESD protection of data lines in accordance with IEC 61000-4-2
(IEC801-2)
u EFT protection of data lines in accordance with IEC 61000-4-4
(IEC801-4)
