Product details
Overview
SI8220BD-D-ISR from Skyworks Solutions is a 2.5 A peak-output isolated gate driver with opto-emulator input, 5.0 kVRMS reinforced isolation (UL1577), 60 ns max propagation delay independent of input drive current, and –40 to +125 °C operating range. It replaces HCPL-3120/HCPL-0302 in IGBT/MOSFET gate drive circuits for industrial inverters and UPS systems.
For engineers reviewing the SI8220BD-D-ISR datasheet, SI8220BD-D-ISR pinout, SI8220BD-D-ISR application, or SI8220BD-D-ISR equivalent, key selection criteria include its 5.0 kVRMS isolation rating, SOIC-16 wide-body package with 8.0 mm creepage/clearance, UVLO hysteresis of 1000 mV (12.5 V threshold), and CMTI of 30 kV/µs - all critical for high-reliability motor control and power conversion designs.
Technical Context
The SI8220BD-D-ISR implements RF-based on/off keying across a silicon isolation barrier, eliminating LED aging and temperature drift inherent in optocouplers. Its input emulates an LED but requires only 5–20 mA forward current, with propagation delay invariant across that range.
It features dual-stage under-voltage lockout (UVLO) with 12.5 V turn-on threshold and 1000 mV hysteresis, ensuring robust startup in noisy industrial supplies. The output stage delivers 2.5 A peak sink/source into capacitive loads up to 200 pF, with <20 ns rise/fall times at 12 V VDD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5.0 kVRMS (1 min, UL1577); enables reinforced insulation per IEC 60950-1/60601-1 in medical and industrial safety-critical systems |
| Peak Output Current | 2.5 A (sink/source); drives high-gate-charge IGBTs and SiC MOSFETs without external buffers in 3-phase inverter legs |
| Propagation Delay | ≤60 ns (tPLH), ≤40 ns (tPHL); tight unit-to-unit matching enables precise timing in interleaved or parallel-switched topologies |
| CMTI | 30 kV/µs minimum; sustains reliable operation during fast dv/dt transients in high-power motor drives and EV chargers |
| Supply Voltage Range | 6.5 V to 24 V VDD; supports direct connection to 12 V/15 V industrial rails without LDO regulation |
| Operating Temperature | –40 °C to +125 °C ambient; qualified per AEC-Q100 Grade 1, suitable for under-hood and factory-floor environments |
| UVLO Threshold | 12.5 V (rising), 11.6 V (falling); prevents erratic switching during brown-out conditions in SMPS and UPS backup modes |
Pinout & Package
SI8220BD-D-ISR is housed in a RoHS-compliant SOIC-16 wide-body package (8.5 mm minimum creepage per VDE), optimized for high-voltage isolation integrity in industrial PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Input side ground / NC | Pins 1–4 are input-side terminals; pins 1–2 are VSS (input GND), pins 3–4 are NC - must be left unconnected or tied to input ground |
| 5, 6 | Anode / Cathode | Differential LED-emulator input; accepts 5–20 mA forward current; polarity-sensitive for proper logic mapping |
| 7, 8 | NC / NC | No-connect; electrically isolated from internal circuitry; must remain floating |
| 9–12 | Output side ground / NC | Pins 9–12 are output-side terminals; pins 9–10 are VSS (output GND), pins 11–12 are NC - tie to local driver ground plane |
| 13, 14 | VDD / VO | VDD (pin 13) powers output stage (6.5–24 V); VO (pin 14) is single-ended gate drive output (2.5 A sink/source) |
| 15, 16 | NC / NC | No-connect; internal isolation barrier boundary; maintain ≥8 mm clearance to adjacent traces |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation architecture | Eliminates LED degradation and temperature drift - ensures stable propagation delay and gain over 15+ years of operation |
| Input current independence | Propagation delay remains ≤60 ns across full 5–20 mA IF range - simplifies MCU/FPGA interface design without current trimming |
| High CMTI (30 kV/µs) | Prevents false triggering during 1500 V common-mode surges in 3-phase bridge drivers - reduces need for snubbers or layout guard rings |
| 12.5 V UVLO with 1000 mV hysteresis | Guarantees clean startup and shutdown in 12 V/24 V battery-backed systems - avoids partial-turn-on of power devices during rail collapse |
| SOIC-16 wide-body isolation | 8.0 mm creepage/clearance meets reinforced insulation requirements for 600 VRMS working voltage per IEC 60664-1 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8230BD-D-ISR | Same SOIC-16 package and 5.0 kVRMS rating, but dual-channel (2x independent outputs) vs. single-channel SI8220BD-D-ISR | Required where space-constrained designs need two isolated drivers (e.g., half-bridge upper/lower) without doubling IC count | Select Si8230BD-D-ISR only when dual-channel functionality is needed; SI8220BD-D-ISR remains optimal for discrete high-side or low-side use cases |
| ADUM4223BRIZ | 2.5 A peak output, 5.0 kVRMS, but uses iCoupler® magnetic isolation; higher supply current (1.8 mA vs. 1.4 mA) and 55 ns tPLH (vs. 60 ns) | Better suited for systems requiring tighter EMI control due to lower radiated emissions from magnetic vs. RF coupling | Choose ADUM4223BRIZ if board-level EMI compliance (CISPR 32 Class B) is prioritized over long-term parametric stability under thermal stress |
Compared with SI8220BD-D-ISR, Si8230BD-D-ISR adds channel density at no isolation or timing penalty, while ADUM4223BRIZ trades RF immunity for lower EMI - making SI8220BD-D-ISR the preferred choice for high-CMTI, thermally demanding industrial motor drives.

FAQ
What is the isolation voltage rating of the SI8220BD-D-ISR and which safety standards does it meet?
The SI8220BD-D-ISR is rated for 5.0 kVRMS isolation per UL1577 (1 minute), with production-tested 6.0 kVRMS. It holds VDE certification to IEC 60747-5-5 (reinforced insulation), CSA approval to IEC 60950-1/61010-1/60601-1, and CQC certification to GB4943.1 - supporting 600 VRMS working voltage in reinforced insulation configurations.
Does the SI8220BD-D-ISR require external components for basic operation?
No, the SI8220BD-D-ISR operates with only two external bypass capacitors: a 0.1 µF ceramic and a 10 µF bulk capacitor placed close to VDD and VSS pins. Its integrated UVLO, RF transmitter/receiver, and output driver eliminate need for external bias networks, level shifters, or timing compensation components required by optocouplers like HCPL-3120.
Can the SI8220BD-D-ISR directly replace HCPL-3120 in existing designs?
Yes, the SI8220BD-D-ISR is a functional and pin-compatible drop-in replacement for HCPL-3120 in SOIC-16 footprints. It matches the same anode/cathode input configuration and single-output topology, while improving propagation delay consistency, CMTI, and thermal stability - requiring only verification of VDD ≤24 V and input current limiting to ≤20 mA.
What is the maximum capacitive load the SI8220BD-D-ISR can drive at 20 kHz switching frequency?
Per Equation 3 in the datasheet, the SI8220BD-D-ISR supports up to 2500 pF load capacitance at 20 kHz with VDD = 18 V, assuming thermal limits are observed. At typical 200 pF gate loads (e.g., 1200 V/100 A IGBT), it delivers full 2.5 A peak current with <20 ns rise time - enabling efficient hard-switching up to 100 kHz.
How does the UVLO behavior of the SI8220BD-D-ISR protect power devices during brown-out conditions?
The SI8220BD-D-ISR features a 12.5 V turn-on threshold with 1000 mV hysteresis (11.6 V turn-off), ensuring VO remains low until VDD stabilizes above 12.5 V and stays asserted until VDD drops below 11.6 V. This prevents partial turn-on of IGBTs/MOSFETs during undervoltage events - eliminating shoot-through risk and gate oxide stress in SMPS and motor drives.
