Overview
The SL15T1G 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, which lowers the capacitance to less than 5 pF, making it suitable for high-speed interfaces in communication systems, computers, and computer peripherals.
