Is there a matching Emitter for the standard NPN phototransistor PT-204 6C from Vishay ?
Thank you for any help
Greetings,
There’s not really a “matching” emitter per-se, because the device is sensitive to light across pretty much the entire visible and near-infrared spectrum; it’ll sense light from just about any emitter one might care to use.
Its peak sensitivity is around 940nm though, so picking one in that ballpark might be a reasonable starting point to narrowing down the options.
