It delivers 3000Vrms isolation in a compact 8-SOIC package, with a data rate of 150Mbps that comfortably handles SPI, UART, and CAN FD isolation without adding bus latency. The 1.7V to 5.5V supply range on each side means it can bridge a 1.8V MCU domain to a 5V peripheral rail without a level shifter — one less component on the BOM. ## 75 kV/µs CMTI — why it matters for motor drives and inverters Common-mode transient immunity is rated at 75kV/µs minimum. In a motor-drive or inverter application where fast-switching IGBTs or SiC FETs slam the ground reference, that CMTI margin keeps the output from glitching. The 13ns propagation delay (max) and 3ns pulse-width distortion mean the isolated signal stays clean enough for timing-critical loops like PWM gating or encoder feedback. ## Temperature grade and storage reality The 8-SOIC package is MSL 3 — store the reels dry; if the moisture-barrier bag has been open past the floor-life window, bake before reflow.","metaTitle":"ADUM121N1BRZ-RL7 iCoupler Digital Isolator, 150Mbps","metaDescription":"ADUM121N1BRZ-RL7 iCoupler digital isolator: 2-ch unidirectional, 150Mbps, 3000Vrms isolation, -40°C to 125°C, 8-SOIC.
