Optocoupler Phototransistors

Würth Elektronik Optocoupler Phototransistors feature 5kV isolation voltage, fast switching time, and good stability of inner isolation. The WL-OCPT series provides an IR LED and phototransistor in one package. These modules offer a stable current transfer ratio (CTR) in a full operating temperature range with different CTR binnings available. Würth Elektronik Optocoupler Phototransistors are ideal for power supplies, office equipment, instrumental applications, computers, and microprocessors.
