APV2121SZ is a photovoltaic MOSFET driver designed for high-speed switching and isolation in power supply and MOSFET driving applications. It features a typical release time of 0.1 ms enabling rapid MOSFET turn-off in urgent situations, with a drop-out voltage of 8.2 V (typical) and short circuit current of 8 µA (typical). The device provides 2,500 V AC I/O isolation voltage in SOP package configuration and operates across a temperature range of -40°C to +85°C. With an input LED forward current rating of 50 mA and peak forward current of 1 A, this driver is ideal for photovoltaic systems, power conversion circuits, and applications requiring reliable galvanic isolation between control and power stages.
