Product details
Overview
SI8220DD-A-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, 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 SI8220DD-A-ISR datasheet, SI8220DD-A-ISR pinout, SI8220DD-A-ISR application, or SI8220DD-A-ISR equivalent, this page delivers verified functional replacement data, SOIC-16 wide-body package details, UVLO thresholds (12.5 V), CMTI (30 kV/µs), and design-meaning specifications - all confirmed against Skyworks Rev. 1.5 documentation.
Technical Context
The SI8220DD-A-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, and propagation delay remains stable regardless of input drive level.
It integrates under-voltage lockout with 12.5 V turn-on threshold (±1.0 V hysteresis) and supports 6.5–24 V gate driver supply. The device delivers 2.5 A peak sink/source output with <20 ns rise/fall times (CL = 200 pF) and maintains 30 kV/µs common-mode transient immunity at full rated isolation voltage.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8220BD-A-ISR | Same SOIC-16 package and 2.5 A drive, but rated for 3.75 kVRMS isolation (not 5.0 kVRMS) | Suitable for 300–400 VRMS working voltage systems where 5.0 kVRMS is not mandated by safety standard | Select when lower isolation rating suffices and cost optimization is prioritized over maximum safety margin |
| HCPL-3120 | Optocoupler-based; 2.5 A peak, but 500 ns propagation delay, higher IF requirement (16 mA typ), and aging-sensitive LED | Legacy designs requiring direct drop-in replacement without layout change - but with degraded timing accuracy and lifetime drift | Choose only for backward compatibility; avoid in new designs due to inferior CMTI (15 kV/µs), temperature drift, and timing variation |
Compared with Si8220BD-A-ISR, SI8220DD-A-ISR provides higher isolation margin for critical safety applications; compared with HCPL-3120, it delivers 8× faster propagation, stable timing, and no LED wear-out - making it the preferred upgrade for high-reliability industrial power systems.

FAQ
What is the isolation voltage rating of SI8220DD-A-ISR?
SI8220DD-A-ISR is rated for 5.0 kVRMS isolation per UL1577 (1 minute test). It is production-tested to 6.0 kVRMS and certified for reinforced insulation per VDE 0884-5 (IEC 60747-5-5) with 891 Vpeak working voltage. This rating applies specifically to the SI8220DD-A-ISR variant and is validated for the SOIC-16 wide-body package.
Does SI8220DD-A-ISR support direct connection to microcontroller GPIO pins?
Yes - SI8220DD-A-ISR accepts 5–20 mA input current and operates with as little as 5 mA, making it compatible with most 3.3 V or 5 V MCU I/O pins. Figure 16C in the Skyworks datasheet explicitly shows direct connection to MCU port pins without external buffering, provided series resistance limits IF to ≤20 mA.
What is the UVLO behavior of SI8220DD-A-ISR?
SI8220DD-A-ISR features under-voltage lockout with a 12.5 V turn-on threshold (VDDUV+ = 12.4–14.8 V) and 11.6–13.8 V turn-off threshold (VDDUV−), yielding 1000 mV hysteresis. Output VO remains low until VDD exceeds VDDUV+, then follows input state - ensuring clean startup in 12–24 V gate supply systems.
How does SI8220DD-A-ISR differ from optocoupler-based drivers like HCPL-3120?
SI8220DD-A-ISR replaces HCPL-3120 with RF-based silicon isolation, delivering 60 ns vs. 500 ns propagation delay, 30 kV/µs vs. 15 kV/µs CMTI, no LED aging, and stable timing across temperature. It requires less input current (5–20 mA vs. 16 mA typ), has tighter part-to-part matching, and supports AEC-Q100 qualification - all while maintaining pin-compatible SOIC-16 footprint.
Is SI8220DD-A-ISR suitable for SiC or GaN MOSFET gate driving?
Yes - SI8220DD-A-ISR's 2.5 A peak output current, <20 ns rise/fall times (CL = 200 pF), and 30 kV/µs CMTI make it well-suited for driving medium-power SiC and GaN MOSFETs in high-frequency topologies. Its stable propagation delay and low output impedance minimize gate ringing and improve switching consistency in fast-switching applications.
