Product details
Overview
SI8220CD-D-ISR from Skyworks Solutions is a 2.5 A peak-output isolated gate driver with silicon-based isolation, 5.0 kVRMS withstand voltage (UL1577), 60 ns max propagation delay, and –40 to +125 °C operation. It replaces optocoupled drivers like HCPL-3120 in IGBT/MOSFET gate drive circuits for industrial inverters and UPS systems.
For engineers reviewing the SI8220CD-D-ISR datasheet, SI8220CD-D-ISR pinout, SI8220CD-D-ISR application, or SI8220CD-D-ISR equivalent, key selection criteria include its 5.0 kVRMS reinforced insulation rating, UVLO hysteresis of 1000 mV (12.5 V threshold), 30 kV/µs CMTI, and SOIC-16 wide-body package compatibility with high-noise motor control environments.
Technical Context
The SI8220CD-D-ISR implements RF-based on/off keying across a semiconductor isolation barrier-replacing LED/photodiode coupling-with input emulation of an LED but requiring only 5–20 mA drive current. Its output stage delivers 2.5 A peak sink/source capability with VOH = VDD–0.1 V and VOL = 50 mV at 50 mA load.
It features programmable undervoltage lockout (UVLO) with 12.5 V turn-on threshold (VDDUV+ = 12.4–14.8 V) and 1000 mV hysteresis, ensuring robust startup under brownout conditions. The device operates with 6.5–24 V gate supply and achieves 20 ns output rise/fall time (CL = 200 pF), enabling high-frequency switching up to several MHz.

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 (2× independent drivers) vs. single-channel SI8220CD-D-ISR | Required where space-constrained designs need two isolated outputs (e.g., half-bridge top/bottom drive) without stacking devices | Select Si8230BD-D-ISR when dual-channel integration reduces PCB area and interconnect complexity versus using two SI8220CD-D-ISR units |
| ADUM4223BRIZ | 2.5 A peak output, 5.0 kVRMS (IEC 60747-5-5), but uses iCoupler® capacitive isolation and has 55 ns tPLH (vs. 60 ns) | Preferred in systems requiring certified functional safety (IEC 61508 SIL2) due to ADI's full safety documentation package | Choose ADUM4223BRIZ for safety-certified industrial PLCs or medical equipment where FMEDA reports and diagnostic coverage are mandatory |
Compared with SI8220CD-D-ISR, Si8230BD-D-ISR offers integrated dual-channel operation at identical isolation and drive strength, while ADUM4223BRIZ provides certified functional safety support but requires different layout practices due to capacitive coupling sensitivity-neither is pin-compatible, and both demand distinct PCB routing and decoupling strategies.

FAQ
What is the isolation voltage rating of the SI8220CD-D-ISR?
The SI8220CD-D-ISR is rated for 5.0 kVRMS isolation per UL1577 (1 minute), with production-tested withstand of 6.0 kVRMS. This corresponds to 891 Vpeak working voltage per IEC 60747-5-5 and qualifies it for reinforced insulation in 600 VRMS systems per CSA/UL/VDE standards-making it suitable for mains-connected industrial inverters and EV chargers.
Does the SI8220CD-D-ISR support both high-side and low-side gate driving configurations?
Yes-the SI8220CD-D-ISR supports both configurations via its floating output stage: VSS serves as the local reference for the driven device, allowing direct connection to high-side IGBT sources or low-side MOSFET sources. Its 6.5–24 V VDD range and 2.5 A peak drive enable robust turn-on/turn-off in either topology without external level shifters.
What is the purpose of the input current hysteresis (IHYS) specification in the SI8220CD-D-ISR?
The 0.5 mA input current hysteresis (IHYS) in the SI8220CD-D-ISR prevents chatter during slow-rising or noisy input transitions-ensuring clean, glitch-free output switching even with marginal MCU GPIO drive or long PCB traces. This eliminates need for external Schmitt triggers in cost-sensitive industrial controls.
How does the UVLO behavior of the SI8220CD-D-ISR differ from traditional optocoupled drivers?
Unlike optocouplers with undefined or weak UVLO, the SI8220CD-D-ISR features tightly specified 12.5 V turn-on (12.4–14.8 V) and 1000 mV hysteresis-guaranteeing VO remains low until VDD stabilizes above threshold. This prevents partial turn-on of power devices during brownouts, protecting IGBTs from shoot-through in critical applications like UPS systems.
Can the SI8220CD-D-ISR replace HCPL-3120 directly in existing designs?
Yes-the SI8220CD-D-ISR is a functional upgrade with pin-compatible SOIC-16 footprint (wide-body), identical ANODE/CATHODE input interface, and enhanced specs: 2.5 A drive (vs. 2.5 A), 60 ns delay (vs. 500 ns), and 30 kV/µs CMTI (vs. 15 kV/µs). Layout changes are minimal; verify VDD ≤24 V and adjust input resistor R1 to limit IF ≤20 mA.
