Its 5 kVrms isolation rating provides the galvanic barrier needed between the low-voltage controller side and the high-voltage power stage, meeting UL approval for motor drives, inverters, and switch-mode power supplies. The 35 kV/µs minimum common-mode transient immunity means the output stays latched correctly when the power-stage midpoint slews at tens of kilovolts per microsecond — a common failure point in hard-switched bridges. ## Switching speed and timing margin for your gate loop Typical rise and fall times of 38 ns and 24 ns let this driver charge and discharge the gate capacitance quickly, keeping switching losses in check for frequencies up to a few hundred kilohertz. Maximum propagation delay is 210 ns for both low-to-high and high-to-low transitions, with a pulse-width distortion of 65 ns max — a tight window that simplifies dead-time budgeting in complementary-switch topologies. The output supply range of 10 V to 30 V covers standard gate-drive rails for silicon IGBTs (15 V) and super-junction MOSFETs (12 V), while the 25 mA maximum forward current keeps the LED drive within a logic-level GPIO output range. ## Package and temperature — what to check before the reflow oven Housed in an 8-SMD Gull Wing package, the FOD3182SD has a standard 1.27 mm pitch footprint — no fine-pitch challenge for standard solder paste stencils, but check the MSL level on the reel label before reflow to avoid popcorning. Rated for -40°C to 100°C operating temperature, it fits industrial environments like motor-drive cabinets, solar inverters, and outdoor telecom power supplies without needing a hermetic package.","metaTitle":"FOD3182SD onsemi Optoisolator – 5 kVrms Gate Driver","metaDescription":"onsemi FOD3182SD optocoupled gate driver: 5 kVrms isolation, 3 A peak output, 35 kV/µs CMTI, -40°C to 100°C.
