Overview
Photocouplers GaAℓAs Infrared LED & Photo IC TLP2451A TLP2451A 1.
Applications • Industrial Inverters • MOSFET Gate Drivers • IGBT Gate Drivers • Induction Cooktop and Home Appliances 2.
General The TLP2451A is a photocoupler in a SO8 package that consists of a GaAℓAs infrared light-emitting diode (LED) optically coupled to an integrated high-gain, high-speed photodetector IC chip.
It provides guaranteed performance and specifications at temperatures up to 125.
The TLP2451A has an internal Faraday shield that provides a guaranteed Common-mode transient immunity of ±20 kV/µs.
It has a totem-pole output that can both sink and source current.
The TLP2451A is ideal for IBGT and power MOSFET gate drive.
