Littelfuse SMF4L Series TVS diodes protect sensitive electronic equipment from voltage transients caused by lightning or other transient events. These diodes feature a low-profile SOD-123FL package for optimized board space in surface-mount designs. The SMF4L series offers fast response times and low inductance for efficient transient suppression. These devices provide peak pulse power dissipation of 400W at 10/1000 µs, a thermal resistance junction-to-ambient of 220°C/W, and an operating temperature range from -55°C to +150 °C. The SMF4L series TVS diodes are suitable for cellular phones, portable devices, power supplies, I/O interfaces, business machines, and consumer applications.
