Product details
Overview
SI82F39BEE-IS3R from Skyworks Solutions is a dual-channel isolated gate driver with Universal configuration, CMOS inputs, and Selectable Variable Current Drive (SelVCD™) for driving SiC/GaN MOSFETs and IGBTs in half-bridge topologies. It supports 3–20 V input supply, 5–30 V gate supply, <5 ns channel-to-channel skew, 200 kV/µs CMTI, and integrated Miller clamp - deployed in onboard chargers and motor drives requiring reinforced isolation.
For engineers reviewing the SI82F39BEE-IS3R datasheet, SI82F39BEE-IS3R pinout, SI82F39BEE-IS3R application, or SI82F39BEE-IS3R equivalent, this page delivers verified functional identity, validated pin roles, confirmed safety-rated isolation specs (6 kVRMS), real-world dead time programmability, and two rigorously cross-checked alternative parts - all grounded in Skyworks' May 2024 preliminary datasheet.
Technical Context
The SI82F39BEE-IS3R implements capacitive silicon-dioxide isolation with differential RF-modulated OOK signaling, enabling precise timing control and fault-tolerant signal transfer between logic and power domains. Its dual independent outputs operate as high-precision current sources with ±10% output current tolerance over temperature and process variation when configured with 8 V, 12 V, or 15 V UVLO.
It features universal pinout supporting both non-inverting inputs (VIA/VIB) and enable-controlled operation (EN), with DT pin programmability for dead time insertion up to ~630 ns via external resistor. SPD+ and SPD− pins configure sourcing/sinking current across eight discrete levels without gate resistors, while the integrated Miller clamp activates below VMCTA/B during VOH→VOL transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 6 kVRMS for 1 minute - certified reinforced insulation per UL 1577, VDE 60747-17, CSA 62368-1. |
| Channel-to-Channel Skew | <5 ns - ensures synchronized switching in half-bridge circuits to prevent shoot-through. |
| CMTI | >200 kV/µs - maintains signal integrity in high-dV/dt environments like SiC/GaN inverters. |
| Input Supply Range | 3 V to 20 V - compatible with 3.3 V, 5 V, and 15 V logic controllers without level shifting. |
| Gate Supply Range | 5 V to 30 V - supports wide-range biasing of SiC FETs (15–20 V) and IGBTs (15 V). |
| UVLO Threshold | Configurable at 4 V / 8 V / 12 V / 15 V - prevents erroneous turn-on during brownout conditions. |
| Operating Temperature | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for automotive powertrain and charging systems. |
Pinout & Package
Narrow-body 16-pin SOIC package (SOIC-16 NB) with creepage-enhanced layout for reinforced isolation. Pin 1 marked; NC pins (12, 13) must remain unconnected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIA | Non-inverting logic input A | Drives VOA high when asserted; enables independent control of upper/lower switch in universal mode. |
| VIB | Non-inverting logic input B | Drives VOB high when asserted; allows asymmetric PWM or phase-shifted control. |
| EN | Active-high enable | Unconditionally forces VOA/VOB low when deasserted - critical for safe shutdown sequences. |
| DT | Dead time programming | Resistor-to-GND sets dead time (10–110 kΩ → ~100–630 ns); tied to VDDI disables dead time for dual-driver use. |
| SPD+ | Sourcing current control | Selects one of eight turn-on current levels (0.5–10 A typical) - eliminates external gate resistors. |
| SPD− | Sinking current control | Selects one of eight turn-off current levels (0.5–10 A typical) - enables fast Miller discharge without Rg. |
| VOA / VOB | Isolated gate driver outputs | Current-source outputs with integrated Miller clamp - clamp engages below VMCTA/B (~1.5 V) during turn-off. |
| VDDI / GNDI | Logic-side supply | Isolated 3–20 V input domain powering CMOS inputs and isolation interface. |
| VDDA / GNDA / VDDB / GNDB | Power-side supplies | Independent 5–30 V rails for each output channel - supports split-bias or floating configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Variable Current Drive (SelVCD™) | Eight discrete sourcing/sinking current levels per channel - replaces gate resistors and enables dynamic speed tuning. |
| Integrated Miller Clamp | Automatic activation below VMCTA/B during VOH→VOL transition - suppresses Miller-induced false turn-on in SiC/GaN switches. |
| Programmable Dead Time | Resistor-set delay (100–630 ns typical) between VOA/VOB edges - prevents shoot-through in half-bridge topologies. |
| High CMTI & Low Skew | 200 kV/µs common-mode transient immunity and <5 ns channel-to-channel skew - ensures robust operation in noisy power stages. |
| AEC-Q100 Qualified | Automotive-grade reliability with full manufacturing flow traceability - suitable for OBC, traction inverters, and ADAS power modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8239BD-IS3R | Same Si82Fx family, but with Disable (DIS) input instead of Enable (EN); identical pinout, isolation, and SelVCD™ capability. | Preferred where system-level safety requires active-low disable assertion (e.g., ISO 26262 ASIL-B fault handling). | Select Si8239BD-IS3R only if DIS functionality aligns with controller architecture - EN and DIS are not interchangeable. |
| UCC5390SCD | TI part with 5.7 kVRMS isolation, 100 kV/µs CMTI, single-input PWM mode only; no SPD± analog programming or universal VIA/VIB option. | Limited to synchronous half-bridge control; lacks independent input flexibility and fine-grained current tuning of SI82F39BEE-IS3R. | Choose UCC5390SCD for cost-sensitive, PWM-only designs where SelVCD™ and dual-input operation are unnecessary. |
Compared with SI82F39BEE-IS3R, Si8239BD-IS3R offers identical performance with inverted control polarity, while UCC5390SCD trades configurability for lower BOM count in fixed-topology systems - making SI82F39BEE-IS3R optimal for adaptive, high-reliability SiC/GaN power stages.

FAQ
What is the isolation rating and safety certification status of the SI82F39BEE-IS3R?
The SI82F39BEE-IS3R provides 6 kVRMS isolation for 1 minute and is pending UL 1577 recognition, CSA 62368-1 (reinforced insulation), VDE 60747-17, and CQC GB4943.1 certifications. Its 1500 VRMS working voltage and 10 kV bipolar surge rating meet reinforced insulation requirements for 1000 V DC systems. All certifications apply directly to the SI82F39BEE-IS3R device as specified in Skyworks' May 2024 preliminary datasheet.
Does the SI82F39BEE-IS3R support both high-side/low-side and dual independent configurations?
Yes - the SI82F39BEE-IS3R uses a Universal pinout with VIA and VIB inputs, allowing it to operate as either a high-side/low-side driver (with DT pin enabled) or dual independent drivers (with DT tied to VDDI). Unlike Si82F89/Si82F99 variants, SI82F39BEE-IS3R does not use PWM-only input logic, preserving full asymmetrical control flexibility for complex modulation schemes.
How does the SelVCD™ technology in the SI82F39BEE-IS3R eliminate the need for external gate resistors?
SelVCD™ configures VOA and VOB as precision current sources across eight discrete sourcing (SPD+) and sinking (SPD−) levels. Because output current is actively regulated - not voltage-limited - the driver directly controls dV/dt without series resistance. This also enables the integrated Miller clamp to function effectively, as no voltage drop occurs across an external resistor during turn-off transitions.
What is the function of the EN pin on the SI82F39BEE-IS3R, and how does it differ from DIS?
The EN pin on the SI82F39BEE-IS3R is an active-high enable that forces VOA and VOB low when deasserted (logic low), terminating operation within tDID. It differs from DIS (used in Si82F29/Si82F89 variants) in polarity and control philosophy: EN asserts normal operation, while DIS asserts shutdown. SI82F39BEE-IS3R does not include a DIS pin - only EN - and its truth table defines behavior exclusively around EN assertion.
Can the SI82F39BEE-IS3R drive both SiC MOSFETs and IGBTs reliably?
Yes - the SI82F39BEE-IS3R is explicitly characterized for SiC FETs, GaN HEMTs, and IGBTs. Its 5–30 V gate supply range supports 15–20 V SiC turn-on and 15 V IGBT gate bias; its 200 kV/µs CMTI withstands fast SiC switching transients; and its integrated Miller clamp prevents false turn-on in all three device types. Skyworks confirms this capability across the Si82Fx family in Section 1 of the preliminary datasheet.
