The surface-mount body sits low enough that no special clearance is needed under a conformal coat or a nearby tall component. Supplied in tube format, which suits pick-and-place reels for volume runs or bench-level hand assembly for prototypes and rework. ## Isolation and signal transfer — what the ratings mean Rated for 2500 Vrms isolation between input and output — this is the one-minute hipot test voltage per UL 1577. It certifies the optocoupler for basic isolation in mains-referenced circuits, such as a 24 VDC PLC input module or a motor-drive feedback path where the control side must stay galvanically separate from the power stage. The DC input side drives an infrared LED with a typical forward voltage of 1.45 V; the transistor output side switches up to 20 V and sinks 8 mA continuous per channel. The 19% to 50% current transfer ratio at 16 mA forward current means the output transistor can saturate with as little as 3 mA of collector current from a 16 mA input — enough margin to drive a logic gate input or a low-power relay coil directly. Switching times are 450 ns turn-on and 300 ns turn-off typical — this places the part in the high-speed optocoupler class, capable of passing 1 MHz data rates cleanly. The asymmetry (faster off than on) is typical of transistor-output couplers; the pull-up resistor value on the output side sets the rise time and should be chosen to keep the RC time constant below the bit period. ## Temperature grade and operating environment The CTR and switching speed are specified at 25°C; expect the CTR to drop by roughly 20% at the cold end and rise slightly above 25°C, but the 19% minimum at 16 mA still provides adequate drive margin across the band. The 25 mA absolute-maximum forward current limits the LED drive; staying below 20 mA at 85°C keeps the junction temperature within the LED's long-term reliability window. The base product number HCPL04 covers a family of single-channel high-speed optocouplers; the HCPL0453 is the transistor-output variant in the 8-SOIC package. ROHS3 compliant (lead-free, no restricted substances per EU 2015/863).","metaTitle":"onsemi HCPL0453 Optoisolator, 1-Ch DC Input, 8-SOIC","metaDescription":"onsemi HCPL0453 optocoupler: 1-channel DC-input transistor output, 2500Vrms isolation, 19-50% CTR, 450ns turn-on.
