CYStek Product Specification
Surface Mount Transient Voltage Suppressors
Peak Pulse Power 200W
Working Voltage 5.0 to 190V
SMF5.0A thru SMF190CA
Features
• Glass passivated chip
• Uni and Bidirectional unit
• Excellent clamping capability
• 200W peak pulse power capability with a 10/1000μs waveform, repetition rate (duty cycle) : 0.01%
• Very-fast response time
• Low leakage
• RoHS compliant
Mechanical Data
• Case : Molded plastic
• Terminals: Pure tin plated, solderable per MIL-STD-750 method 2026
• Polarity: For uni-directional types, the band denotes the cathode, which is positive with respective to the anode
under normal TVS operation
• Mounting position : Any
• Epoxy: UL 94V-0 rate flame retardant
Devices for bidirectional applications
For bi-directional devices, use suffix CA (e.g. SMF10CA). Electrical characteristics apply in both directions.
