The VDRH10S300BSE is a surface-mount, single-phase Transil surge protection device from Vishay. It is designed to protect sensitive electronic equipment from voltage surges, such as those caused by electrostatic discharge (ESD) events, and lightning strikes. This device has a standoff voltage of 300 V, and can safely absorb up to 10 A of surge current. It has an integrated bidirectional thyristor with a fast response time of 1 ns to protect equipment from both positive and negative surges. The VDRH10S300BSE is housed in a SOD-323 package, which makes it suitable for use in space constrained applications.
