2P102A Datasheet PDF

Transformers and opto-isolators are the only two classes of electronic devices that offer reinforced protection — they protect both the equipment and the human user operating this equipment. From Wikipedia, the free encyclopedia. An optocoupled solid-state relay contains a photodiode opto-isolator which drives a power datasheey, usually a complementary pair of MOSFETs. To minimize eatasheet delays, fast digital opto-isolators contain their own LED vatasheet and output amplifiers optimized for speed.

American guitar and organ manufacturers of the s embraced the resistive opto-isolator as a convenient and cheap tremolo modulator. This article is about the electronic component. It transforms useful input signal into light, sends it across the dielectric channel, captures light on the output side and transforms it back into electric signal. Low to high [note 7].

Si LEDs have current transfer ratio of around 0. Photoresistors used in 2102 rely on bulk effects in a uniform film of semiconductor ; there are no p-n junctions.

If necessary, the gap between two LEDs can be extended with a glass fiber insert. Opto-isolators rated for 2. Si Dztasheet are the preferred choice for datashwet devices. Each coil can act as a primarypumping energy into a common magnetic coreor as a secondary — picking up energy stored in the core. The turn-on and turn-off lag of an incandescent bulb lies in hundreds of milliseconds range, which makes the bulb an effective low-pass filter and rectifier but limits the practical modulation frequency range to a few Hertz.


The majority of opto-isolators on the market use bipolar silicon phototransistor sensors. Because LEDs can sense light in addition to emitting it, construction of symmetrical, bidirectional opto-isolators is possible. Diode opto-isolators employ LEDs as sources of light and silicon photodiodes as sensors. Views Read Edit View history.

All opto-isolators described so far are uni-directional. Retrieved November 2, The main function of an opto-isolator is to block such high voltages and voltage transients, so that a surge 2p1022 one part of the system will not disrupt or destroy the other parts.

Devices rated for less than a few kV have planar or sandwich construction. A common type of opto-isolator consists of an LED and a phototransistor in the same opaque package.

Photodiode opto-isolators can be used for interfacing analog signals, although their non-linearity invariably distorts the signal. The proposed configuration consist of two different parts.

This proposed analog isolator is linear over a wide range of input voltage and frequency. Retrieved from ” https: Unlike transformers, which pass energy in both directions [note 3] with very low losses, opto-isolators are unidirectional see exceptions and they cannot transmit power. This mode of operation is called photoconductive mode. The energy is harvested by draining the charge through an external high-impedance path; the ratio of current transfer can reach 0.

Phototransistors are inherently slower than photodiodes. The response times of PIN diodes lie in the subnanosecond range; overall system speed is limited by delays in LED output and in biasing circuitry. Commons category link is locally defined Wikipedia articles with GND identifiers.

In applications where control linearity was not important, or where available current was too low for driving an incandescent bulb as was the case in vacuum tube amplifiersit was replaced with a neon lamp.

Ternary and quaternary GaAsP photodiodes can generate light. Alternatively, in the absence of external bias the diode converts the energy of light into electric energy by charging its terminals to a voltage of up to 0. An unrelated company, Silonex a division of Carlyle Group brands its photoresistive opto-isolators Audiohm Optocouplers. By using this site, you agree to the Terms of Use and Privacy Policy.

Fender ‘s early tremolo effects used two vacuum tubes ; after one of these tubes was replaced by an optocoupler made of a LDR and a neon lamp.
