The 50 kV/µs common-mode transient immunity (CMTI) ensures the output stays clean during fast switching events, which is the spec that matters when the part sits on a noisy half-bridge ground plane. ## 68 ns propagation delay — timing margin for dead-time Maximum propagation delay is 68 ns for both low-to-high and high-to-low transitions. That number sets the lower bound on dead-time you can program in the PWM controller — too tight and you risk shoot-through. The 12 ns typical rise and fall time keeps the gate drive edges crisp, which helps reduce switching losses in the power FETs or IGBTs. ## Package and approvals Housed in an 8-SOIC narrow-body package (3.90 mm width), surface-mount. Safety approvals include CSA, UR, and VDE — the marks that matter when the end equipment must pass IEC 62368-1 or UL 61800-5-1 for motor drives.","metaTitle":"ADUM3123ARZ iCoupler Gate Driver, 3000Vrms, 4A Peak, 8-SOIC","metaDescription":"ADUM3123ARZ single-channel isolated gate driver, 3000Vrms isolation, 4A peak output, 50kV/µs CMTI.

That figure sets the lower bound on dead-time you can program in the PWM controller."},{"question":"Can ADUM3123ARZ be used to drive IGBTs and SiC MOSFETs?","answer":"Yes. The 4 A peak output and 4.5 V to 18 V supply range cover the gate charge requirements of many IGBTs and SiC MOSFETs. The 50 kV/µs CMTI keeps the output stable during the fast switching transients typical of SiC devices."},{"question":"What is the difference between ADUM3123ARZ and ADUM3123BRZ?","answer":"The ADUM3123BRZ is a higher-speed variant with a 62 ns maximum propagation delay versus 68 ns for the ARZ. Both share the same 4 A peak output, 3000 Vrms isolation, and 50 kV/µs CMTI. The BRZ buys you 6 ns of timing margin on the propagation delay spec."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM3123ARZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM3123ARZ when reusing this data.
