Product details
Overview
SI8220DD-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, and –40 to +125 °C operation. It replaces HCPL-3120/HCPL-0302 in IGBT/MOSFET gate drive circuits for industrial inverters and UPS systems.
For engineers reviewing the SI8220DD-D-ISR datasheet, SI8220DD-D-ISR pinout, SI8220DD-D-ISR application, or SI8220DD-D-ISR equivalent, key selection criteria include isolation voltage rating (5.0 kVRMS), output current capability (2.5 A peak), UVLO threshold (12.5 V typ), CMTI (30 kV/µs), and SOIC-16 wide-body package compatibility with high-voltage power stage layouts.
Technical Context
The SI8220DD-D-ISR implements RF-based on/off keying across a silicon isolation barrier-replacing LED/photodiode coupling-to deliver stable timing independent of input drive current. Its dual-channel architecture supports high-side/low-side gate driving with matched propagation delays (tPLH ≤ 60 ns, tPHL ≤ 40 ns) and tight part-to-part variation (14× better than opto-drivers).
It integrates under-voltage lockout with 12.5 V rising threshold (±1.4 V hysteresis), operates from 6.5–24 V VDD, and features robust transient immunity (30 kV/µs CMTI) and thermal derating up to 150 °C case temperature. The device is AEC-Q100 qualified and certified to UL1577, VDE IEC 60747-5-5, CSA C22.2 No. 5A, and CQC GB4943.1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5.0 kVRMS (1 min, UL1577); enables reinforced insulation for 600 VRMS working voltage per VDE/IEC standards |
| Peak Output Current | 2.5 A (10 µs pulse, 0.2% duty); sufficient to drive high-capacitance IGBT gates in motor drives |
| Propagation Delay | tPLH ≤ 60 ns, tPHL ≤ 40 ns (CL = 200 pF); ensures precise timing control in high-frequency SMPS |
| CMTI | ≥30 kV/µs; maintains signal integrity during fast dV/dt transients in inverter half-bridges |
| UVLO Threshold | VDDUV+ = 12.4–14.8 V (12.5 V nominal); prevents erratic switching during brown-out conditions |

Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation barrier | Eliminates LED aging drift and temperature-dependent timing variation seen in opto-couplers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8230AD-D-ISR | Same SOIC-16 package, 2.5 A output, but 3.75 kVRMS isolation and 8 V UVLO threshold | Suitable for lower-isolation industrial controls where 5.0 kVRMS is not mandated | Select when regulatory requirements permit 3.75 kVRMS and 8 V UVLO suffices for system brown-out margin |
| HCPL-3120-000E | Optocoupled driver; 2.5 A output, 3.75 kVRMS, 60 ns propagation delay, no integrated UVLO | Lacks silicon-isolation benefits: higher temperature drift, looser timing matching, and lower CMTI (15 kV/µs) | Use only for legacy opto-replacement where redesign for silicon isolation is not feasible |
Compared with Si8230AD-D-ISR, SI8220DD-D-ISR provides higher isolation (5.0 vs. 3.75 kVRMS) and higher UVLO (12.5 vs. 8 V), making it preferable for high-reliability UPS and EV applications; versus HCPL-3120-000E, SI8220DD-D-ISR eliminates LED aging, improves timing stability, and doubles CMTI-justifying migration despite identical pin count.

FAQ
What is the isolation voltage rating of the SI8220DD-D-ISR?
The SI8220DD-D-ISR is rated for 5.0 kVRMS isolation per UL1577 (1 minute), with production-tested withstand voltage of 6.0 kVRMS. This corresponds to 891 VPEAK working voltage under IEC 60747-5-5 and qualifies it for reinforced insulation in 600 VRMS systems per VDE and CSA standards.
Does the SI8220DD-D-ISR support both high-side and low-side gate driving configurations?
Yes, the SI8220DD-D-ISR supports both configurations via its isolated output domain (pins 9–16). Its VO pin delivers 2.5 A peak sink/source current, and VDD/VSS pins allow flexible local bootstrap or floating supply implementation-enabling direct connection to high-side IGBT gates in half-bridge topologies without external level-shifting circuitry.
What is the under-voltage lockout (UVLO) behavior of the SI8220DD-D-ISR?
The SI8220DD-D-ISR features a programmable UVLO with 12.5 V nominal rising threshold (VDDUV+ = 12.4–14.8 V) and 1.0 V hysteresis. When VDD falls below VDDUV− (11.6–13.8 V), VO is forced low. This prevents partial turn-on of power devices during undervoltage conditions, protecting IGBTs/MOSFETs from thermal overstress.
Can the SI8220DD-D-ISR replace HCPL-3120 directly in existing PCB layouts?
No-although functionally compatible, SI8220DD-D-ISR uses a SOIC-16 wide-body package (10.3 mm width), while HCPL-3120 uses SOIC-8 narrow-body (3.9 mm width). Direct replacement requires board rework. However, Skyworks provides pin-compatible SOIC-8 variants (e.g., SI8220BB-D-IS) for drop-in upgrades where space permits.
What safety certifications does the SI8220DD-D-ISR hold?
The SI8220DD-D-ISR holds UL1577 recognition (File E257455), VDE certification to IEC 60747-5-5 (File 5006301-4880-0001), CSA Component Acceptance Notice 5A (File 232873), and CQC certification to GB4943.1-2011 (Certificates CQC13001096107/109). All apply to its 5.0 kVRMS-rated variant.
