SMF51A DATASHEET:SMF Series_v2211.1.pdf



SMF51A Description:
The SMF series of transient voltage suppressors is designed to protect sensitive electronic equipment from transient voltages caused by lightning and other transient voltage events that can damage electronic equipment and interfere with normal use of the equipment.

SMF51A Features:

• Low leakage
• Uni-directionaal and Bi-directional unit
• Passivated junction glass
• Low inductance
• Excellent ability to clamp and unclamp
• Matt Tin Lead Free
• Halogen free and RoHS compliant
• Compatible with industrial standard package SOD-123
• For optimising board space in surface mount applications
• High Temperature soldering: 260℃/40 seconds at terminals
• Typical maximum temperature coefficient ΔVBR = 0.1% × VBR@25℃×ΔT
• Plastic package has Underwriters Laboratory Flammability 94V-0
• Typical failure mode is short due to over voltage or over current.
• 200W Peak power capability at 10 × 1000μs waveform Repetition rate (duty cycle):0.01%
• Fast response time: typically less than 1.0ps from 0 Volts to VBR min
• Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c
• IEC-61000-4-2 ESD 15kV(Air), 8kV (Contact)
• ESD protection of data lines in accordance with IEC 61000-4-2 (IEC801-2)
• EFT protection of data lines in accordance with IEC 61000-4-4 (IEC801-4)

SMF51A Applications:
TVS devices are ideally suited to telecommunications, consumer electronics, computer and industrial applications for the protection of I/O interfaces, VCC buses and other sensitive circuits.
