SMF4L Transient Voltage Suppressor Diodes

Taiwan Semiconductor SMF4L Transient Voltage Suppressor (TVS) Diodes offer 400W of peak power dissipation in a small SOD-13W package. These devices feature junction passivation optimized design technology, providing low power losses and high efficiency. SMF4L TVS diodes are ideal for automated placement and designed to protect sensitive circuits from damage by high-voltage transients.
