The 2500Vrms isolation rating means it provides basic galvanic isolation between control and load circuits — enough to break ground loops and protect low-voltage logic from transient spikes on the secondary side, but not reinforced for mains-line safety isolation in medical or industrial power supplies. The transistor-with-base output gives you the option to bias the base for faster turn-off or to use the phototransistor as a simple switching element without external drive. Switching is specified at 450 ns turn-on and 500 ns turn-off typical — fast enough for 1 MHz data rates or isolated gate drive at moderate frequency, but not a digital isolator replacement for high-speed communication links like I²C or SPI above a few MHz. ## Where this part fits in the BOM The current transfer ratio (CTR) is specified at 7% minimum and 50% maximum at 16 mA forward current — a wide spread that means the downstream logic must be designed to work with the weakest unit; a 7% CTR at 16 mA input yields only about 1.1 mA output current, which is below the 8 mA rated output per channel. For reliable switching, drive the input LED at the 16 mA test point and ensure the load side can trigger on a 1 mA signal. Maximum forward current is 25 mA DC, and the typical forward voltage is 1.45 V — the input LED is standard 5 V logic compatible with a current-limiting resistor. The output transistor can sink up to 20 V and 8 mA, so it directly drives small relays, CMOS logic inputs, or a downstream transistor stage. It ships in Tube format, not tape-and-reel — factor this into your pick-and-place feeder setup; a tube-fed machine needs a tube handler or a bulk-to-tape conversion step. The 8-SOIC footprint is standard and matches many other single-channel optocouplers, so a second-source swap is straightforward at layout time. ## Lifecycle and compliance onsemi lists the HCPL0500 as Active and ROHS3 Compliant — no end-of-life notice, no restricted substances.","metaTitle":"onsemi HCPL0500 Optocoupler, 1-Ch Transistor Output, 8-SOIC","metaDescription":"onsemi HCPL0500 single-channel optocoupler, transistor output with base, 2500Vrms isolation, 8-SOIC surface mount.
