Littelfuse, Inc. has recently introduced a new family of transient suppression diodes designed to safeguard sensitive, portable, and compact electronic devices from voltage transients. The SMF3.3 series features an ultra-small SOD-123FL plastic package that delivers 200W surge performance, a low reverse off-state voltage of 3.3V, and a low clamping voltage of 6.8V. This makes it particularly well-suited for use in a wide range of portable and compact electronics.
The SMF3.3 series is ideal for low-voltage applications, such as protecting the VCC bus and other delicate circuits found in portable devices, external hard drives, laptops, point-of-sale (POS) terminals, solid-state drives (SSDs), power supplies, and display systems. Its advanced design ensures reliable protection against transient overvoltage events, helping to extend the lifespan of critical components.
Jeff Chin, Global Product Marketing Director for Littelfuse Semiconductor Products, commented, “The SMF3.3 series combines exceptional surge performance with low reverse off-state and clamping voltages, giving circuit designers more options for low-voltage protection. The compact SOD-123FL package is especially well-suited for modern portable and consumer electronics where space is at a premium.â€
Key benefits of the SMF3.3 TVS diode series include:
- A low clamping voltage of 6.8V and a low reverse off-state voltage of 3.3V, making it perfect for protecting sensitive equipment from overvoltage damage.
- A small, flat-pin SOD-123FL package measuring just 1.08mm in height, which helps optimize board space and is ideal for use in compact designs.
- Excellent ESD immunity and superior circuit protection, ensuring products meet or exceed the highest IEC standards and perform reliably in real-world conditions.
The SMF3.3 series is available in tape and reel packaging, with a minimum order quantity of 3,000 units. Free samples are also available through authorized Littelfuse distributors worldwide. For a full list of authorized dealers, visit littelfuse.com.
