Semtech SurgeSwitch™ Circuit Protection | Datasheet Preview
Semtech's SurgeSwitch circuit protection provides highly effective protection against electrical overstress and electrostatic discharge events. These devices have superior clamping and stability over temperature compared to standard TVS devices. Unlike TVS diodes, SurgeSwitch devices do not use a conventional PN junction for the breakdown mechanism. Instead, these devices employ a surge-related FET with a driving circuit as the primary surge current shunting element, effectively working as voltage-controlled switches. A precisely tuned trigger circuit activates the shunt FET when an electrical overstress event is detected. The FET switches on and safely diverts transient current to the ground to safeguard the integrated circuit. The SurgeSwitch circuit protection is in a small footprint package with multiple voltage options available. They feature a surge immunity level 2 as per IEC 61000-4-5 and have an ESD immunity that exceeds level 4.
