Overview
The SZSL05T1G is a Transient Voltage Suppressor (TVS) diode from onsemi, designed to provide transient overvoltage protection with significantly reduced capacitance. This device integrates a compensating diode in series, resulting in a capacitance of less than 5 pF. This makes it ideal for protecting high-speed interfaces in communication systems, computers, and computer peripherals against Electrostatic Discharge (ESD) and other transient voltage conditions.
