Description

The HCPL-4502, HCPL-2503, 6N135, 6N136 and HCPL-2530, HCPL-2531 optocouplers consist of an AlGaAs LED optically coupled to a high speed photodetector transistor.

A separate connection for the bias of the photodiode improves the speed by several orders of magnitude over conventional phototransistor optocouplers by reducing the base-collector capacitance of the input transistor.

An internal noise shield provides superior common mode rejection of 10kV/µs. An improved package allows superior insulation permitting a 480 V working voltage compared to industry standard 0f 220 V.

Features

1. High speed-1 MBit/s

2. Superior CMR-10 kV/µs

3. Double working voltage-480V RMS

4. CTR guaranteed 0-70°C

 

 

Applications:

1. Line receivers

2. Pulse transformer replacement

3. Output interface to CMOS-LSTTL-TTL

4. Wide bandwidth analog coupling

Description

MOC7811 is Optocoupler. An optocoupler, also known as an optoisolator or photocoupler, is an electronic device that combines an optical transmitter (typically an LED) and an optical receiver (usually a phototransistor or photodiode) in a single package. It is designed to provide electrical isolation between input and output circuits.

The optocoupler functions by using light to transmit signals between the input and output sides of the device while maintaining electrical isolation. When an input signal is applied to the LED, it emits light. The light is then detected by the phototransistor or photodiode on the output side, which generates a corresponding electrical signal.

Slotted couplers consist of an infrared emitting diode facing a photodetector in a molded plastic housing. A slot in the housing between the emitter and the detector provides a means of interrupting the signal. A wide selection of standard and custom housings and detector fuctions is available.
