Help with Phototransistors specifications:
Phototransistor Type
Back to Top
|
| ||
| Your choices are... | |||
| Phototransistor | A transistor that is sensitive to incident radiation. The incident photons result in a base current that is then amplified by the gain of the transistor. | ||
| Photodarlington | A phototransistor, the collector and emitter that is connected to the collector and base respectively, of a second transistor. | ||
| Other | Any other phototransistor type not listed. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||

|
| ||
| Peak Wavelength | The wavelength at which the detector is most responsive. | ||
| 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 Current | The amount of current flowing into the collector terminal of a transistor. | ||
| 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 Dark Current | The amount of current flowing into the collector terminal of a transistor when there is no optical input. | ||
| 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 (nondestructive) current much higher than the normal leakage currents, which 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. | ||
| |||
| Power Dissipation | Maximum power that a device can safely dissipate under specified conditions, which include ambient temperature, heat sinking, and air circulation. | ||
| 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. | ||
| |||
| Operating Temperature | The temperature range the phototransistor was 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. | ||

Mounting Option
Back to Top
|
|
| ||
| 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. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||

|
|
| ||
| Visible Cutoff Filter | The phototransistor has a filter that blocks visible light. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Antireflective Coating | The phototransistor has an antireflective coating to improve light detection. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Dome Lens? | The lens is rounded instead of flat. Rounded lenses are more common than flat ones in this type of application. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
