The ADUM241E0BRWZ-RL is a 4-channel, unidirectional digital isolator from the iCoupler family, built around magnetic coupling. It delivers 150 Mbps data rate across a 5000 Vrms isolation barrier.
Isolation rating and transient immunity — the real-world limits
The 5000 Vrms isolation rating is the reinforced-class figure for 1-minute withstand — the spec that decides whether this part goes into a medical front-end, a motor-drive phase-leg, or a grid-tied power supply. The 75 kV/µs CMTI is what protects the data during a fast common-mode step, like the switching node of a half-bridge. If your layout has a long creepage path under the SOIC-16 package, the 7.50 mm body width gives you room to maintain clearance between primary and secondary ground planes. The 2.5 ns typical rise/fall time and 13 ns max propagation delay keep the timing budget tight enough for 150 Mbps NRZ data; pulse-width distortion stays under 3 ns, so duty-cycle-sensitive signals like PWM won't drift across the barrier.
