Its 5300Vrms isolation rating is the headline spec — this is the figure that determines whether the part safely separates two circuits that must not share a ground path, such as a 24V PLC input from a sensor on a different power domain. The current transfer ratio (CTR) spans 160% to 320% at 10mA forward current. That means at 10mA in the LED, the output transistor can sink at least 16mA and up to 32mA — a wide enough margin to drive a logic input or a low-current relay coil without extra gain stages. The 400mV Vce saturation max at that drive level keeps the voltage drop low enough to stay within the logic-low threshold of a 5V or 3.3V receiver. ## Switching speed and temperature envelope Typical rise and fall times are 2µs each, with turn-on at 3µs and turn-off at 2.3µs. For a 24V DC sensor input sampling at 1kHz, this is plenty fast — the output settles well before the PLC scan reads it. But if you're pushing into the tens-of-kilohertz range for a serial data isolator, the 2µs edges will limit the bit rate to roughly 50 kbps before pulse-width distortion becomes a problem. The 70V maximum output voltage and 50mA per-channel current rating mean this part handles standard 24V logic rails and can drive a small relay or a MOSFET gate directly through a current-limiting resistor. ## Package, compliance, and procurement posture The Gull Wing leads are visible for solder inspection and rework-friendly — a standard hot-air profile at 260°C peak works fine, though the part is MSL-rated for the moisture sensitivity level typical of this package style. Vishay lists this part as Active in production and fully RoHS3 compliant. There is no last-time-buy clock ticking — the part is a standard catalog item. For current pricing and availability, submit an RFQ; the quote confirms the lot date code and the sourcing channel (authorized distribution or independent stock, depending on quantity and lead time).","metaTitle":"Vishay SFH615A-4X017T Optoisolator, 5.3kV, 4-SMD","metaDescription":"Vishay SFH615A-4X017T optoisolator, 5300Vrms isolation, 160-320% CTR, transistor output, 4-SMD Gull Wing.
