SMF15A Description

Short technical summary and product information.

The Littelfuse SMF15A is a unidirectional TVS diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It features a reverse standoff voltage of 15V and a maximum clamping voltage of 24.4V at a peak pulse current of 8.2A.

 

This device offers a peak pulse power dissipation of 400W for a 10/1000µs waveform and 2000W for an 8/20µs waveform. It provides ESD protection up to 30kV for both air and contact discharge per IEC 61000-4-2. The SMF15A is part of the SMF4L series and is housed in a low-profile SOD-123FL package with a maximum height of 1.08mm.

 

The SMF15A is suitable for general-purpose applications including I/O interfaces, VCC bus protection, and other vulnerable circuits in consumer electronics, portable devices, and power supplies. It is RoHS compliant, halogen-free, and meets MSL level 1 per J-STD-020.
