It delivers a 2.5 A peak output current with 5300 Vrms isolation between the logic-side input and the power-stage output. The 25 kV/µs minimum common-mode transient immunity keeps the output state stable when the power stage switches at high dv/dt — a requirement for SiC and GaN inverter stages where fast edges couple noise across the isolation barrier. ## Parametric limits that set the drive budget The output supply range of 15 V to 32 V covers the typical gate-drive rails for IGBT modules (15 V on, -5 V to -8 V off) and standard MOSFET drivers. The 2.5 A source and sink current is symmetric, so turn-on and turn-off gate charge delivery are balanced — no need for a separate pull-down resistor on the gate. Propagation delay is 400 ns max for both tpLH and tpHL, with a pulse-width distortion ceiling of 200 ns. For a 20 kHz PWM carrier, that delay adds about 0.8 % dead-time error — the controller's dead-time insertion must account for this. Rise and fall times are 100 ns typical, which limits the gate-drive edge rate. For a 10 nC gate charge (typical of a 50 A IGBT module), the 2.5 A peak charges the gate in roughly 4 ns, but the 100 ns rise time is dominated by the optocoupler's internal output stage, not the external gate resistor. ## Active production — no LTB watch needed Approvals include cUR, UR, and VDE, which satisfy the safety-agency requirements for reinforced insulation in motor-drive and power-supply designs sold into North American and European markets.","metaTitle":"VO3120-X019T Vishay Optoisolator – 5300 Vrms","metaDescription":"VO3120-X019T Vishay optocoupler gate driver: 5300 Vrms isolation, 2.5 A peak output, 25 kV/µs CMTI, 8-SMD gull wing.
