Low-Profile, Small-Footprint 400W TVS Diodes from Littelfuse Protect Sensitive Electronics from Damage from Transient Voltage Events

Press release date: May 17, 2016

Protection for portable devices/hard drives, notebooks, VCC busses, POS terminals, SSDs, power supplies, monitors

CHICAGO – Littelfuse, Inc., the global leader in circuit protection, has introduced the SMF4L Series 400W Low Profile Package TVS Diode, which is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It is provided in a small-footprint, flat lead, low-profile plastic SOD-123FL package. With a board footprint of just 3.10mm x 2.00mm x 0.98mm, the SMF4L Series is 50 percent smaller than SMA. Its maximum height profile of just 0.98mm and 400W@10/1000µs peak pulse power dissipation capability allows the SMF4L Series to fit neatly into transient voltage protection applications where compact design is critical.

Applications for the SMF4L Series include protection of portable devices/hard drives, notebooks, VCC busses, POS terminals, SSDs, power supplies and monitors.

“The SMF4L Series is a great addition to our portfolio of general-purpose transient voltage protection devices,” said Jeff Chin, Product Line Director /TVS Diode. “With voltage ranges from 5V to 85V and a very compact package, design engineers can be confident that they will find a device that both protects sensitive circuitry and fits neatly into their crowded PCB layout.”

All SMF4L Series TVS Diodes offer these key benefits:

They offer 400W @ 10/1000µs peak pulse power dissipation in a SOD-123FL footprint that’s just half the size of SMA package.

The industry-standard, low-profile SOD-123FL plastic package is just 0.98mm (max.) high, which makes it well-suited for use in compact designs.

With standard voltage ranges from 5V to 85V, designers can easily choose the most suitable component for their design and applications.

Availability
The SMF4L Series is available in a surface mount SOD-123FL package and is provided in tape & reel packaging in quantities of 3,000. Sample requests can be placed through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit Littelfuse.com.
