The ACPL-P481-500E is a single-channel logic output optocoupler from the Broadcom ACPL series, housed in a stretched SO-6 surface-mount package. It features a propagation delay of up to 350 ns with rise and fall times of 16 ns and 20 ns respectively. The device supports a maximum continuous output current of 25 mA and operates within a temperature range of -40°C to +100°C. Key electrical parameters include a forward voltage of 1.5 V at 10 mA input, a reverse voltage rating of 5 V, and power dissipation of 210 mW. It provides an isolation voltage of 3750 Vrms.
Verify the specific suffix '500E' against official datasheets to confirm insulation voltage ratings and RoHS compliance status. Ensure the ordered component matches the required SO-6 Stretched package dimensions and pinout configuration. Cross-reference manufacturer part numbers to avoid confusion with similar ACPL-P481 variants that may have different electrical characteristics or packaging options.
Select this component when inverted logic signaling is required for gate drive isolation. The high common-mode rejection ratio makes it suitable for noisy environments typical in power electronics. Verify that the 3750 Vrms isolation rating meets system safety standards and that the 10 mA forward current requirement aligns with the driving circuit capabilities.
This device belongs to the ACPL-P series of high-speed optocouplers manufactured by Broadcom Limited. The series is engineered for robust performance in industrial and automotive-grade applications requiring reliable signal transmission across isolation barriers. The ACPL-P481 variant specifically targets applications needing inverted logic outputs for precise timing control.
ACPL-P481-000E is a documented substitute within the same family.
