Its 5000 Vrms isolation rating creates a reinforced safety barrier between the low-voltage PWM controller and the high-voltage power stage — the minimum for motor drives, solar inverters, and industrial PSUs that must meet IEC 60747-17 or UL 1577 reinforced isolation requirements. The 6 A peak output current with 4 A source and 4 A sink capability directly charges and discharges the gate capacitance of a power MOSFET or IGBT. For a typical 10 nC gate charge at 15 V, the rise and fall times are 12 ns typ, keeping switching losses low in a 100 kHz hard-switched converter. The 116 ns max propagation delay sets the minimum dead-time budget — a bridge leg running at 200 kHz with 500 ns dead time has 384 ns of margin before the shoot-through window opens. Common-mode transient immunity of 125 kV/µs means the output state holds through the fast dv/dt edges at the switching node of a half-bridge — a SiC or GaN FET switching at 50 V/ns produces a 2.5 kV/µs transient across the isolation barrier, well within the part's rejection capability. This prevents the false turn-on that would short the bridge leg. ## Supply rails and temperature grade — the operating envelope The output side runs from 5.5 V to 30 V, covering the standard gate-drive bias rails for silicon MOSFETs (10-15 V), IGBTs (15-20 V), and SiC FETs (18-20 V). The -40°C to 125°C operating temperature range covers the full industrial ambient envelope. In a motor-drive cabinet with internal heating, the 125°C ceiling provides margin above the typical 85°C ambient. The 14-SOIC wide-body package with 7.50 mm body width and 0.295-inch lead spacing meets the creepage distance for 5 kV reinforced isolation per IEC 60950-1. ## Active lifecycle and compliance — no end-of-life risk It is ROHS3 compliant and holds safety approvals from CQC, CSA, UL, and VDE, covering the key regulatory jurisdictions for industrial and power-conversion equipment sold in China, North America, and Europe.","metaTitle":"SI823H3BD-IS3 Skyworks Digital Isolator, 5 kV","metaDescription":"Skyworks SI823H3BD-IS3 single-channel gate-drive isolator with 5 kVrms isolation, 6 A peak output, 125 kV/µs CMTI.","metaKeywords":null},"attributes":{"series":"Si823Hx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Series":"Si823Hx","Package":"Tube","Technology":"Capacitive Coupling","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.295\\\", 7.50mm Width)","Approval Agency":"CQC, CSA, UL, VDE","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"5000Vrms","Current - Peak Output":"6A","Operating Temperature":"-40°C ~ 125°C","Rise / Fall Time (Typ)":"12ns, 12ns (Max)","Supplier Device Package":"14-SOIC","Voltage - Output Supply":"5.5V ~ 30V","Current - Output High, Low":"4A, 4A","Pulse Width Distortion (Max)":"5ns","Propagation Delay tpLH / tpHL (Max)":"116ns, 116ns","Common Mode Transient Immunity (Min)":"125kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.85","stockQuantity":15,"priceTiers":[{"qty":1,"price":"$6.85000","currency":"USD"},{"qty":10,"price":"$6.18900","currency":"USD"},{"qty":25,"price":"$5.90080","currency":"USD"},{"qty":100,"price":"$5.12370","currency":"USD"},{"qty":250,"price":"$4.89344","currency":"USD"},{"qty":500,"price":"$4.46168","currency":"USD"},{"qty":1000,"price":"$3.88598","currency":"USD"},{"qty":2500,"price":"$3.74205","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2bf2532b07d1bc23d7703eeff346ea58.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will SI823H3BD-IS3 drop into a board specified around SI823H3AD-IS3 without rewiring?","answer":"The SI823H3BD-IS3 and SI823H3AD-IS3 share the same Si823Hx series, same 14-SOIC wide-body package, same 5 kV isolation, same 6 A peak output, same 125 kV/µs CMTI, and same 12 ns rise/fall times. The only parametric difference is the propagation delay — 116 ns max for the H3BD vs 30 ns max for the H3AD. The pinout and footprint are identical, so the H3BD drops in without a board spin. The slower propagation delay does not affect DC or low-frequency switching but reduces the achievable dead-time margin in a high-frequency bridge — verify the timing budget at the target switching frequency before"},{"question":"What compliance documentation does Skyworks Solutions provide for SI823H3BD-IS3?","answer":"The part is ROHS3 compliant and carries safety certifications from CQC, CSA, UL, and VDE.
