Three-channel iCoupler with 150 Mbps and 5 kV isolation
It delivers a 150Mbps data rate with 2.5ns typical rise/fall times and 13ns max propagation delay per channel, making it a fit for high-speed SPI, UART, or general-purpose isolated data links.
75 kV/µs CMTI — the spec that matters in noisy environments
Common-mode transient immunity is rated at 75kV/µs minimum, which is the parameter that determines whether the output stays clean when a high-voltage switching node slams the barrier with a fast dV/dt event. In a motor-drive or SiC/GaN inverter application, the isolation barrier sees edges that can exceed 50 kV/µs; the 75kV/µs margin here means the receiver won't glitch or lose data. The 3ns max pulse-width distortion also helps keep the duty cycle intact across the barrier, which matters for PWM or timing-sensitive signals.
Package and layout — 16-SOIC wide-body
The part comes in a 16-SOIC wide-body package (7.50mm body width) with surface-mount terminations. The 8 mm creepage and clearance typical of this package supports the 5000Vrms isolation rating, but the board layout must maintain that spacing under the part and across the isolation gap — no copper or traces under the body. No isolated power is provided internally; each side needs its own supply rail (1.7V to 5.5V).
Lifecycle and compliance
The iCoupler series has broad second-source coverage through ADI's own portfolio and authorized distribution; for dual-sourcing, the ADUM131D0BRWZ is a pin-compatible 3-channel variant (same package, same isolation, same data rate) with a 3/0 input-side/side-2 split if the direction mapping fits the application.
