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

*by A***E on Reviewed in Italy on 4 December 2021*

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
  

*by B***L on Reviewed in the United States on 28 April 2023*

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!!!
  

*by T***E on Reviewed in the United States on 6 January 2022*

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!)
