It sits between a controller and its SPI peripherals where galvanic isolation is required — think motor-drive feedback paths, PLC I/O modules, or any industrial bus that crosses a safety barrier. The 7 channels break down as 3 on side 1 and 4 on side 2, all unidirectional, which maps neatly to the standard SPI signals plus a couple of extra control lines or a secondary chip select. Rated for 3750Vrms isolation. 2Mbps data rate with 25ns propagation delay per direction. Supply range runs from 3V to 5.5V on both sides, so it plays with 3.3V or 5V logic without a level-shifter — useful when the controller is 3.3V and the peripheral side lives at 5V in an industrial backplane. Common-mode transient immunity is rated at 25kV/µs minimum, which is the spec that tells you whether the isolator will glitch when a motor drive switches a high-voltage rail or a relay coil dumps its field. At 25kV/µs it handles fast industrial transients without corrupting the SPI frame. ## Package and footprint reality Housed in a 20-pin SSOP with 0.209-inch body width and 5.30mm body height. Surface-mount only — no through-hole variant. The 20-SSOP footprint is common enough that you won't be hunting for a custom land pattern, but the 0.65mm pitch means hand-soldering is fiddly without a hot-air station. ## Lifecycle — still a current design-in part ROHS3 compliant, so it clears the current environmental compliance gates without an exemption. For the sourcing desk: this is a standard catalog part from ADI, available through the usual distribution channels, not a legacy or niche item that requires a broker hunt.","metaTitle":"ADUM3153ARSZ SPI Digital Isolator, 3750Vrms, 2Mbps, 20-SSOP","metaDescription":"ADI ADUM3153ARSZ iCoupler SPI isolator: 7 unidirectional channels, 3750Vrms isolation, 2Mbps data rate, -40 to 125°C.
