6N137 OPTOCOUPLER

The H11A1 is an industry standard single channel photo transistor coupler. The optocoupler consists of gallium arsenide infrared LED and a silicon NPN photo transistor.

The HCPL-4504 contain a GaAsP LED. The LED is optically coupled to an integrated high gain photo detector. The HCPL-4504 series has short propagation delays and high CTR.

1. Applications ? Industrial Inverters ? Air Conditioner Inverters ? IGBT Gate Drivers ? MOSFET Gate Drivers ? Induction Cooktop and Home Appliances 2. General The TLP250H is a photocoupler in a DIP8 package that consists of a GaA?As infrared light-emitting diode (LED) optically coupled to an integrated high-gain, high-speed photodetector IC chip. It provides guaranteed performanceand specifications at temperatures up to 125.?The TLP250H has an internal Faraday shield that provides a guaranteed Common-mode transient immunity of ?40 kV/?s. It has a totem-pole output that can both sink and source current. The TLP250H is ideal for IGBT and power MOSFET gate drive. 3.
