400W Transil™ Transient Voltage Suppressors (TVS)

STMicroelectronics 400W Transil™ Transient Voltage Suppressors (TVS) are ideal for applications such as solar inverters, set-top boxes, and MOSFET protection. The 400W TVS series offers best-in-class performance at full power, even with high junction temperatures. STMicroelectronics 400W Transil suppressors feature a peak power dissipation of up to 400W.
