Product details

What this isolated gate driver brings to a power stage

The ADUM4120ARIZ-RL is a single-channel isolated gate driver from Analog Devices' iCoupler series, built around magnetic coupling technology. It delivers 2.3 A peak output current across a reinforced 5000 Vrms isolation barrier, with a common-mode transient immunity of 150 kV/µs minimum.

Timing budget and switching performance

Propagation delay is specified at 69 ns (low-to-high) and 79 ns (high-to-low) maximum, with pulse-width distortion held to 16.5 ns max. These numbers set the dead-time window you need to program in the controller to avoid shoot-through.

Package and approvals for industrial deployment

The part carries CSA, UR, and VDE safety approvals, which simplifies certification in equipment destined for North American and European markets. ROHS3 compliant per the listing.

It is recommended for new designs.

Frequently asked questions

Can ADUM4120ARIZ-RL drive IGBTs or MOSFETs directly?

Yes. With 2.3 A peak output and a 4.5 V to 35 V output supply range, it directly drives the gate of medium-power IGBTs and MOSFETs in half-bridge and full-bridge topologies. The 150 kV/µs CMTI ensures the output stays clean during fast dV/dt events on the switching node.

How does ADUM4120ARIZ-RL compare to ADUM4121ARIZ-RL?

Both parts share the same 2.3 A peak output, 5000 Vrms isolation, and 150 kV/µs CMTI. The ADUM4121ARIZ-RL offers faster propagation delay (42/53 ns vs 69/79 ns) and lower pulse-width distortion (13 ns vs 16.5 ns), which matters when you need tighter dead-time control in high-frequency switching stages.
