The ADUM230E0BRIZ is a 3-channel digital isolator from Analog Devices' iCoupler series using magnetic coupling. All three channels run unidirectional from Side 1 to Side 2 — there is no bidirectional or reverse-direction channel. This matters if your design needs an isolated feedback path or a bidirectional data line; you will need a second device or a different channel configuration for that. Rated for 5000Vrms isolation with a minimum common-mode transient immunity of 75kV/µs, this part is built for environments where fast-switching power stages (motor drives, inverters, switch-mode supplies) try to slam transients across the barrier. The 75kV/µs figure means the output holds its state through a 75kV/µs common-mode slew — if your system runs SiC or GaN stages, that number is the one to check against your worst-case dv/dt. Data rate hits 150Mbps with 2.5ns typical rise/fall times and a maximum propagation delay of 13ns. Pulse-width distortion stays under 3ns. At 150Mbps the part handles high-speed SPI, parallel GPIO isolation, or clock distribution without struggling — but note the unidirectional constraint: you cannot use one channel as a bidirectional data line without external direction control. Supply range spans 1.7V to 5.5V on both sides, so it can bridge 1.8V, 2.5V, 3.3V, and 5V logic domains without external level shifters.
Package and footprint — what the 16-SOIC wide-body means for your board
The ADUM230E0BRIZ comes in a 16-SOIC wide-body package (7.50mm body width). That is the standard SOIC-16W footprint — the same land pattern used by most 5kV-rated digital isolators in this package. The wide body gives 8mm creepage between the input and output sides, which is what allows the 5000Vrms isolation rating. If your layout is tight on board area, note that a narrow-body SOIC-16 (3.90mm width) will not pass the same isolation voltage; the wide body is a deliberate choice for reinforced insulation. No isolated power output on this part.
Lifecycle and compliance — no end-of-life watch needed
The iCoupler series has broad second-source overlap within the ADuM family, but this specific 3-channel unidirectional 5000Vrms variant is an Analog Devices proprietary part — there is no pin-compatible second source from another manufacturer. For dual-sourcing, consider the ADuM230D or ADuM231D family members that offer similar ratings with different channel direction combinations.
