That peak current is enough to drive medium-power IGBTs and MOSFETs directly — no external booster buffer needed for modules up to about 50 A rating at moderate switching frequencies. The 35 kV/µs minimum common-mode transient immunity keeps the output from false-triggering when the power-stage drain/collector voltage slews through the isolation barrier capacitance, a real concern in half-bridge inverter legs. ## Switching speed and dead-time margin Typical rise and fall times are 50 ns each, with maximum propagation delay of 250 ns and pulse-width distortion capped at 100 ns. For a 20 kHz switching inverter, the 250 ns propagation delay eats about 0.5% of the switching period — negligible for dead-time budgeting. The 2.5 A source/sink capability means the gate charge is delivered symmetrically, so turn-on and turn-off delays stay matched. ## Supply range and forward LED drive Output-side supply range is 3 V to 15 V, covering standard gate-drive voltages for both logic-level MOSFETs (5 V) and IGBTs (12–15 V). The input LED forward voltage is 1.45 V typical, with a maximum DC forward current of 25 mA — a 330 Ω series resistor from a 3.3 V or 5 V logic rail lands the LED current near 10–15 mA, well within the limit. ## Package, MSL, and reflow considerations Housed in a 16-SOIC wide-body package (0.295-inch body width, 7.50 mm), the FOD8333R2 uses a standard SOIC-16 footprint — no exotic pad geometry. The part is supplied in Tape & Reel (TR) or Cut Tape (CT) options. ROHS3 compliant.
