The 5000Vrms isolation rating provides reinforced insulation for safety-critical designs, while the 3A peak output and 2.5A symmetrical sink/source capability handle the gate charge of medium-power switches without an external booster stage. ## Parametric deep-dive: timing, drive strength, and transient immunity Propagation delay is 210ns max for both tpLH and tpHL, with pulse width distortion held to 65ns max — this keeps switching dead-time predictable and minimises asymmetry in half-bridge topologies. Rise and fall times are 38ns and 24ns typical, fast enough for switching frequencies up to several hundred kHz, though the actual frequency ceiling depends on total gate charge and supply voltage. Common mode transient immunity is rated at 20kV/µs minimum, which prevents false turn-on when high dv/dt transients couple across the isolation barrier in inverter legs. The output supply range is 10V to 30V, covering standard gate drive voltages for IGBTs (15V) and MOSFETs (12V-18V). Forward voltage is 1.5V typical with a 25mA maximum forward current, compatible with 3.3V and 5V logic interfaces through a series resistor. ## Lifecycle, compliance, and sourcing The part is ROHS3 compliant and carries UR agency approval. ## Package and mounting Housed in a 6-SOIC package with 0.268-inch body width (6.80mm), designated as 6-SOP by onsemi. Surface-mount assembly on standard SOIC-6 footprint. Supplied in Tape & Reel or Cut Tape for both prototyping and production reels.","metaTitle":"FOD8342R2 onsemi Optocoupler Gate Driver 5000Vrms 3A 6SOP","metaDescription":"onsemi FOD8342R2 optocoupler gate driver, 5000Vrms isolation, 3A peak output, 2.5A sink/source, 20kV/µs CMTI, -40°C to 100°C, 6-SOP package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Technology":"Optical Coupling","Mounting Type":"Surface Mount","Package / Case":"6-SOIC (0.268\\\", 6.80mm Width)","Approval Agency":"UR","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"5000Vrms","Current - Peak Output":"3A","Operating Temperature":"-40°C ~ 100°C","Rise / Fall Time (Typ)":"38ns, 24ns","Supplier Device Package":"6-SOP","Voltage - Output Supply":"10V ~ 30V","Current - Output High, Low":"2.5A, 2.5A","Pulse Width Distortion (Max)":"65ns","Voltage - Forward (Vf) (Typ)":"1.5V","Current - DC Forward (If) (Max)":"25 mA","Propagation Delay tpLH / tpHL (Max)":"210ns, 210ns","Common Mode Transient Immunity (Min)":"20kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.74","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.74000","currency":"USD"},{"qty":10,"price":"$1.82400","currency":"USD"},{"qty":100,"price":"$1.40330","currency":"USD"},{"qty":500,"price":"$1.26856","currency":"USD"},{"qty":1000,"price":"$1.09017","currency":"USD"},{"qty":2000,"price":"$1.03071","currency":"USD"},{"qty":5000,"price":"$1.00692","currency":"USD"},{"qty":10000,"price":"$0.99106","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/cbc6746a01fb7a0925d323ebdd48f047.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum Vcc for FOD8342R2?","answer":"The output supply range is 10V to 30V.
