It provides 5000 Vrms of galvanic isolation across a 16-SOIC package, with all three channels configured as inputs on Side 1 and outputs on Side 2 — the 3/0 input count means no reverse-direction channel is available, so this part is a straight-through isolator for signals flowing from one domain to the other. The 150 Mbps data rate supports high-speed interfaces like SPI, UART, and general-purpose digital I/O without adding timing margin headaches. ## 150 Mbps and 13 ns propagation delay — timing budget for the isolation barrier With a maximum propagation delay of 13 ns (tpLH / tpHL) and pulse-width distortion held to 3 ns max, this isolator fits into most 50–100 MHz clocked interfaces without forcing a slower bus speed. The 2.5 ns typical rise/fall time keeps signal edges clean enough for 150 Mbps NRZ data, but the unidirectional channel layout means you need a separate part if your bus requires bidirectional handshaking. For SPI isolation, the three channels cover SCK, MOSI, and CS — MISO would need a second device or a bidirectional isolator. ## 75 kV/µs CMTI — why it matters for motor drives and inverters The minimum common-mode transient immunity of 75 kV/µs is the spec that separates this part from slower, lower-CMTI isolators. In a variable-frequency motor drive or a switched-mode power supply, the high-side floating node can slew hundreds of volts in nanoseconds. If the isolator cannot reject that transient, data errors appear on the low-voltage side. This rating means the ADUM230D1BRWZ is sized for industrial inverter and servo-drive environments where common-mode dv/dt exceeds 50 kV/µs. Both sides must be powered — there is no isolated power output (the Isolated Power field is No), so you still need a separate DC-DC converter to create the isolated secondary-side rail.","metaTitle":"ADUM230D1BRWZ Digital Isolator, 150 Mbps, 5000 Vrms, 3-Ch","metaDescription":"ADUM230D1BRWZ iCoupler 3-channel unidirectional digital isolator, 150 Mbps data rate, 5000 Vrms isolation, -40°C to 125°C.
