Sono FOTODIODI, non sono "fototransistor" ne, tantomeno, LED.

Sono fotodiodi, esattamente come da titolo della pagina Amazon.Io stesso avevo dubbi prima d'acquistarli, perché la pagina è a dir poco fuorviante se non inesatta.NON vi aspettate che emettano luce, naturalmente.I fotodiodi, al contrario, RILEVANO luce.Vengono impiegati in tutte le applicazioni in cui servano le cosiddette (obsolete) "fotocellule", fotoresistenze.Il loro comportamento è semplice: se la polarizzazione è diretta la resistenza è bassissima (si comportano come consueti, normalissimi diodi), se invece sono connessi con polarizzazione inversa la loro resistenza varia proporzionalmente alla ricezione di luce, e va da circa mezzo megaOhm al buio completo a qualche centinaio di Ohm quando esposti a luce intensa, quindi nei circuiti si utilizzano architetture in cui sono generalmente connessi in polarità invertita rispetto ai normali diodi.Possono essere anche impiegati in applicazioni in cui si rilevi la debole corrente prodotta: i fotodiodi quando colpiti da luce emettono corrente rilevabile da appositi circuiti.Funzionano egregiamente, lo spettro di luce rilevato è ampio e centrato su luce bianca (NON sono fotodiodi sensibili all'infrarosso).Appena arrivati li ho immediatamente montati su circuiti di mia produzione e ho già rilevato comportamento assolutamente corretto e omogeneo (resistenza praticamente quasi identica tra tutti i fotodiodi del pacchetto nei miei dispositivi con luce LED fissa, di rilevamento materiali e logica contapezzi.5 stelle meritate.

Datasheet

Based on the information provided on the HiLetgo description the photo transistors are PT334-6C. Google this number for the datasheet.

They're NOT Diodes!!!! But They ARE Excellent Transistors!!!

These are Everlight PT334-6C photo transistors. I've used over a dozen different phototransistors and these definitely work the best for reflective IR work, if you use the datasheet, which the seller provides upon request (or just google it). Be Aware: the Collector(+) is the SHORT lead, located on the NOTCHED side of the package. The Emitter(-) is the longer lead. This is reverse of some manufactures. Using just two 840nm LEDs @30mA, I can get the PT334-6C to trigger a 555 timer with a direct beam distance >1 meter (reflected beam distance >20"). Terrific sensitivity without the need for an external lens!! Due to the clear package, this transistor IS sensitive to ALL light, but is heavily biased to near-IR frequencies, so a filter, hood or tube is required.UPDATE: Added 1 star for responsive service; Seller updated post with correct product information. (thank you!)

got my need fulfilled

opto isolation circuit, fixed. too many spares remaining, but what the heck, low price.

Great for Arduino Light Sensor

These work great. I make a voltage divider type circuit with these and a 10K resistor. I chose these over photoresistors for ambient light sensors for 2 reasons. The first is that since these are the shape of standard 5mm leds, they can be mounted in an enclosure using 5mm led holders which makes them easy to mount in enclosures. The second is that these are sensitive to a wide range of wavelengths from infrared to ultraviolet. Now ideally for an ambient light sensor, you only want to measure visible light, but I wanted to be able to use these on other projects like with infrared lasers, so I needed them to detect infrared too. When using touch screens in the car, the sun can hit at such an angle that it’s not really hitting the light sensor dead on, but is casting at an angle on the screen and washing the picture out. So I was hoping with the extra infrared light that the sun puts out compared to indoor lighting, that the arduino could overcompensate and increase the brightness.Overall these work well, mount cleanly, and have a wide range of sensitive wavelengths so these are great little sensors.
