New TVS Diodes Guard Sensitive Electronics against Transients: Littelfuse

200W surge capability, low reverse standoff voltage and low clamping voltage are well-suited for portable electronics 

The SMF3.3 offers an ideal circuit protection solution for low voltage electronic applications such as the protection of V_CC busses and other vulnerable circuits used in portable devices, portable hard drives, notebooks, POS terminals, solid-state drives (SSDs), power supplies, and monitors.

Features

• Low clamping voltage of 6.8V, low reverse standoff voltage of 3.3V (low clamping factor V_CL/V_BR) and 200W surge capability
• SOD-123FL small and flat lead low-profile plastic package; compatible with industrial standard, with a height of only 1.08mm
• Promotes high ESD immunity and superior protection: ESD, IEC 61000-4-2, ±22kV contact, ±22kV air discharge; EFT, IEC 61000-4-4, 40A (5/50ns)

Benefits

• Excellent surge capability makes it ideal for protecting sensitive devices against transient over-voltages
• Optimizes the use of circuit board space. Also, due to its small size, it is good for designing into portable devices/hard drives, notebooks, V_ccbusses, POS terminals, SSDs, power supplies, monitors and other consumer applications
• Permits manufacturers to achieve ESD protection beyond the maximum level stated in the IEC standard and protects against a multitude of other threats to ensure product reliability in the field
