Its 5300 Vrms isolation rating and 35 kV/µs common-mode transient immunity make it suited for motor-drive inverters, UPS systems, and industrial power supplies where high-side floating supplies and fast switching edges are present. The output supply range of 15 V to 30 V covers standard gate-drive rails for IGBTs. ## Switching speed and timing margins Typical rise and fall times of 35 ns each and a maximum propagation delay of 500 ns keep the switching dead-time predictable — important for preventing shoot-through in half-bridge topologies. Pulse-width distortion is held to 70 ns maximum, which preserves the duty-cycle accuracy of the PWM signal through the isolation barrier. ## Active production — no obsolescence concern Through-hole 8-DIP format suits prototype builds, low-volume production, and designs where rework access is a priority. Approvals include CQC, cUL, UL, and VDE — the VDE mark is often a requirement for European mains-connected equipment. ## Design-in checklist for the gate-drive path The input LED forward voltage is 1.37 V typical with a maximum forward current of 20 mA — a series resistor from the logic supply is needed to limit current. The 8-DIP (0.300-inch, 7.62 mm) footprint is a standard through-hole layout — verify the pin spacing matches the existing PCB drill pattern before committing the BOM.","metaTitle":"VOD3120AD Vishay Optoisolator – 2.5A IGBT/MOSFET Driver","metaDescription":"VOD3120AD Vishay optocoupled IGBT/MOSFET driver. 2.5A peak output, 5300Vrms isolation, 35kV/µs CMTI, -40°C to 105°C.

The 15 V to 30 V output supply range matches standard IGBT gate-drive voltages. Verify the total gate charge of your IGBT against the drive current and switching frequency to ensure the 500 ns propagation delay meets your dead-time budget."},{"question":"Can the VOD3120AD be used with 5V logic?","answer":"A series resistor from a 5 V logic output (e.g., 330 Ω to 470 Ω) will set the LED current to approximately 8–11 mA, which is within the safe operating range. The output side still requires a separate 15 V to 30 V supply for the gate-drive stage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/VOD3120AD","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/VOD3120AD when reusing this data.
