5000Vrms isolation with 2.3A peak drive
The ADUM4120-1CRIZ: It delivers a 2.3A peak output current, enough to drive medium-power IGBTs and SiC MOSFETs in motor drives, inverters, and switch-mode power supplies. The 150kV/µs minimum common-mode transient immunity keeps the output state stable when fast-switching nodes slam the barrier with dv/dt — a spec that matters in half-bridge and full-bridge topologies where the high-side driver references a swinging source.
Propagation delay and timing margin
Maximum propagation delay is 42ns low-to-high and 58ns high-to-low, with pulse-width distortion capped at 16.5ns. The 18ns typical rise and fall times are symmetric, which simplifies dead-time calculation in a bridge driver — you budget the worst-case spread, not the typical. The 11.6V to 35V output supply range lets the gate drive voltage match the power switch's specification, whether that is a standard 15V IGBT or a 20V-class SiC MOSFET.
Package and approvals
Housed in a 6-SOIC-IC package with 7.50mm body width — the wide-body SOIC that provides the creepage distance for the 5000Vrms rating. Surface-mount assembly, standard reflow profile. CSA, UR, and VDE approval agency listings mean the part carries recognized safety marks for reinforced insulation in equipment destined for North American and European markets.
