Optocoupler Output

![]() | ||
Your choices are... | |||
Photocell | Photocells are light-dependent resistors. They are used to detect changes in light intensity. | ||
Photodiode | A two-electrode, radiation-sensitive junction formed in a semiconductor material in which the reverse current varies with illumination. | ||
Phototransistor | A bipolar transistor used as a photodetector. It provides current at its output that is proportional to light intensity at its input. The low-level input light current is amplified by the current gain (beta) of the transistor. | ||
Photodarlington | A pair of bipolar transistors connected in a darlington configuration to provide very high current gain and often used as the photodetector section of an optocoupler. | ||
Other | Any other output type not listed. | ||

Isolation Voltage | The input-to-output voltage withstanding capability of an optically coupled isolator. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
![]() | |||
Rise Time | The time that elapses while a pulse waveform increases from 10% to 90% of its maximum value. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
![]() | |||
Collector Emitter Breakdown Voltage: | The voltage at which a transistor, biased in the normal direction with no optical or electrical input to the base, will conduct a specified current much higher than the normal leakage currents that occur at lower voltages. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
![]() | |||
Resistance On: | The resistance of the optocoupler when activated. | ||
Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
![]() | |||
Operating Temperature | The temperature range the optocoupler is designed to operate in. | ||
Search Logic: | User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria. | ||

![]() | ||
Your choices are... | |||
Surface Mount | In Surface Mount Technology (SMT), components are mounted on printed circuit boards by soldering the component leads or terminals to the top surface of the board. | ||
Flat Pack | An IC package with gull wing or flat leads on two or four sides. | ||
Through Hole (Plug-in) | In Through Hole Technology (THT), components are mounted on printed circuit boards by inserting component leads through holes in the board and then soldering. | ||
Other | Other, not specified, package. | ||
