Product details
Overview
SI8220DB-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 SI8220DB-D-ISR datasheet, SI8220DB-D-ISR pinout, SI8220DB-D-ISR application, or SI8220DB-D-ISR equivalent, key selection criteria include its 5.0 kVRMS isolation rating, SOIC-16 wide-body package, UVLO hysteresis of 1000 mV (12.5 V threshold), 30 kV/µs CMTI, and compatibility with 6.5–24 V gate supply rails.
Technical Context
The SI8220DB-D-ISR implements RF-based on/off keying across a silicon isolation barrier-replacing LED/photodiode coupling-to deliver stable timing independent of input current. Its input emulates an LED but requires only 5–20 mA forward current, with VF = 1.7–2.5 V at IF = 5 mA.
Internally, it integrates under-voltage lockout with 12.5 V turn-on threshold (VDDUV+ = 12.4–14.8 V) and 1000 mV hysteresis, plus output drivers capable of sourcing 1.5 A and sinking 2.5 A into capacitive loads up to 200 pF. Propagation delays are tPLH ≤ 60 ns and tPHL ≤ 40 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5.0 kVRMS (1 min, UL1577); production tested to 6.0 kVRMS - enables reinforced insulation per IEC 60950-1/61010-1 in high-voltage industrial systems. |
| Peak Output Current | 2.5 A sink / 1.5 A source - drives high-gate-charge IGBTs and SiC MOSFETs without external buffers in motor control inverters. |
| Propagation Delay | tPLH ≤ 60 ns, tPHL ≤ 40 ns (CL = 200 pF) - supports >1 MHz switching frequencies with tight timing control in SMPS and UPS. |
| Common-Mode Transient Immunity | ≥30 kV/µs - maintains signal integrity during fast dV/dt events in bridge-leg configurations with high-side switching. |
| Supply Voltage Range | VDD = 6.5–24 V - compatible with standard 12 V and 15 V gate driver rails; supports wide-input industrial power supplies. |
| Operating Temperature | –40 to +125 °C - qualified per AEC-Q100 Grade 1, suitable for under-hood automotive and harsh industrial environments. |
| Input Forward Voltage | VF = 1.7–2.5 V at IF = 5 mA - matches legacy optocoupler biasing while reducing drive power by >50% vs. HCPL-3120. |
Pinout & Package
SI8220DB-D-ISR uses a RoHS-compliant SOIC-16 wide-body package (8.5 mm minimum creepage/clearance) with reinforced insulation for 600 VRMS working voltage. Pin 1 is ANODE; Pin 2 is CATHODE; Pins 3–4 and 13–16 are NC; Pin 5 is VO; Pin 6 is VSS; Pin 7 is VDD; Pin 8 is NC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (ANODE) | Input anode terminal | Accepts 5–20 mA forward current; connects to MCU/FPGA I/O or open-drain driver via series resistor. |
| 2 (CATHODE) | Input cathode terminal | Reference for input LED emulator; must be tied to system ground or low-side return path. |
| 5 (VO) | Output driver terminal | High-current gate drive output; sources up to 1.5 A, sinks up to 2.5 A into MOSFET/IGBT gates. |
| 6 (VSS) | Output-side ground reference | Return path for VO; may be biased above or below system ground, enabling high-side floating drive. |
| 7 (VDD) | Output-side supply rail | Provides power to output stage; accepts 6.5–24 V; requires local 0.1 µF + 10 µF decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| RF-based isolation architecture | Eliminates LED aging and temperature drift-enables <1% unit-to-unit propagation delay variation over life and temperature. |
| Programmable UVLO threshold | 12.5 V turn-on with 1000 mV hysteresis-prevents erratic gate switching during brown-out conditions in 24 V industrial rails. |
| High CMTI performance | ≥30 kV/µs common-mode rejection-ensures reliable operation in half-bridge topologies with >500 V/ns dV/dt. |
| Opto-replacement compatibility | Pin-compatible drop-in replacement for HCPL-3120 and HCPL-0302-no PCB redesign required for legacy upgrades. |

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-IS | Same SOIC-16 package, 2.5 A output, but 3.75 kVRMS isolation and 8 V UVLO threshold. | Suitable for lower-isolation systems (e.g., 300 VRMS working voltage) where 5.0 kVRMS is not mandated. | Select when regulatory compliance requires only 3.75 kVRMS and cost optimization is prioritized over maximum isolation margin. |
| HCPL-3120 | Optocoupler-based; 2.5 A output but 0.4–1.0 mA IF sensitivity, 500 ns typical propagation delay, no integrated UVLO. | Legacy designs with existing opto-bias networks; lacks CMTI >15 kV/µs and thermal stability of silicon isolation. | Choose only for backward compatibility in non-safety-critical, low-frequency (<50 kHz) applications where upgrade path is constrained. |
Compared with Si8230AD-D-IS, SI8220DB-D-ISR provides higher isolation margin (5.0 vs. 3.75 kVRMS) and tighter UVLO hysteresis control (1000 mV vs. 600 mV), making it preferable for medical-grade and grid-tied inverters. Versus HCPL-3120, it delivers 8× faster propagation, eliminates LED aging, and adds robust UVLO-justifying redesign where reliability and efficiency are critical.

FAQ
What is the isolation voltage rating of the SI8220DB-D-ISR?
The SI8220DB-D-ISR is rated for 5.0 kVRMS isolation per UL1577 (1 minute), with production testing at 6.0 kVRMS. It achieves reinforced insulation per IEC 60950-1 and IEC 61010-1 up to 600 VRMS working voltage, validated for SOIC-16 wide-body package creepage and clearance.
Does the SI8220DB-D-ISR require external components for basic operation?
Yes-the SI8220DB-D-ISR requires local decoupling: a 0.1 µF ceramic capacitor and a 10 µF bulk capacitor between VDD and VSS. An input series resistor (R1) is also needed to limit ANODE–CATHODE current to 5–20 mA; value depends on driving source voltage and logic levels.
Can the SI8220DB-D-ISR replace HCPL-3120 without PCB changes?
Yes-SI8220DB-D-ISR is a pin-compatible, drop-in replacement for HCPL-3120 in SOIC-16 footprint. It matches the same pinout (ANODE/CATHODE/VO/VDD/VSS), operates from the same 12–15 V supply, and emulates LED input behavior-requiring only minor R1 adjustment to limit IF ≤20 mA.
What is the under-voltage lockout behavior of the SI8220DB-D-ISR?
The SI8220DB-D-ISR features fixed 12.5 V UVLO with hysteresis: VO remains low until VDD rises above 12.4–14.8 V (VDDUV+), then stays active until VDD falls below 11.6–13.8 V (VDDUV−). This 1000 mV hysteresis prevents oscillation during rail instability in industrial power systems.
Is the SI8220DB-D-ISR qualified for automotive applications?
Yes-the SI8220DB-D-ISR is AEC-Q100 qualified (Grade 1, –40 to +125 °C), supporting under-hood and powertrain applications. Its 5.0 kVRMS isolation, 30 kV/µs CMTI, and robust UVLO make it suitable for EV traction inverters and onboard chargers requiring reinforced insulation.
