Product details
Overview
CS8101YTHA5G from onsemi is a high-speed, low-power dual-channel digital isolator with reinforced isolation rating of 5 kVRMS, 100 Mbps data rate, and ±100 kV/µs common-mode transient immunity (CMTI), designed for isolated communication in industrial PLC I/O modules and motor drive gate driver interfaces.
For engineers reviewing the CS8101YTHA5G datasheet, pinout, applications, or equivalent options, key selection criteria include reinforced isolation compliance (UL 1577, VDE 0884-11), dual-channel unidirectional configuration, 3.0–5.5 V supply range, and operation across –40°C to +125°C ambient temperature.
Technical Context
The CS8101YTHA5G implements capacitive isolation using onsemi's proprietary silicon-dioxide dielectric barrier, supporting two independent unidirectional signal channels with separate VDD1/VDD2 supplies. It features integrated noise filtering and failsafe output logic (high-impedance default on power loss).
It complies with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) immunity standards at system level, and supports 10-year lifetime under rated isolation stress per VDE 0884-11 Annex A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 5 kVRMS reinforced isolation per UL 1577 & VDE 0884-11 - enables safe separation between functional and safety-critical domains in industrial control. |
| Data Rate | 100 Mbps - supports high-speed serial interface protocols including SPI clock lines and fast PWM feedback loops. |
| CMTI | ±100 kV/µs - ensures robust signal integrity in noisy motor drive and inverter environments with rapid voltage transients. |
| Supply Voltage | 3.0 V to 5.5 V on both sides - allows interoperability with 3.3 V microcontrollers and 5 V legacy logic without level-shifting. |
| Operating Temperature | –40°C to +125°C - qualified for extended thermal range in enclosed industrial enclosures and under-hood automotive auxiliary systems. |
| Failsafe Output | High-impedance on power loss - prevents unintended gate drive activation during brown-out or supply sequencing faults. |
Pinout & Package
CS8101YTHA5G is housed in a compact SOIC-8 wide-body package (SO-8WB) with creepage/clearance ≥8.3 mm, optimized for reinforced isolation and PCB-level pollution degree III compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD1) | Primary-side supply | Provides 3.0–5.5 V power for input-side logic and channel 1 transmitter. |
| 2 (GND1) | Primary-side ground | Reference return for VDD1 and input-side signals; must be separated from secondary ground by isolation barrier. |
| 3 (IN1) | Channel 1 input | TTL/CMOS-compatible digital input driving isolated output OUT1; no external pull-up required. |
| 4 (IN2) | Channel 2 input | Independent TTL/CMOS input for second isolated path; supports asynchronous signal routing. |
| 5 (OUT2) | Channel 2 output | Isolated CMOS output referenced to VDD2/GND2; drives downstream gate drivers or MCU inputs. |
| 6 (OUT1) | Channel 1 output | Isolated output with propagation delay <15 ns (typ); matched to OUT2 for synchronous timing-critical paths. |
| 7 (GND2) | Secondary-side ground | Return for VDD2 and output-side circuitry; galvanically isolated from GND1. |
| 8 (VDD2) | Secondary-side supply | Independent 3.0–5.5 V supply for output-side logic and channel 2 receiver. |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Isolation | UL 1577 & VDE 0884-11 certified - eliminates need for external isolation components in safety-rated systems. |
| Dual Unidirectional Channels | Two independent signal paths (IN1→OUT1, IN2→OUT2) - enables bidirectional control without cross-talk or timing skew. |
| High CMTI Performance | ±100 kV/µs - maintains signal fidelity in high-di/dt motor control and SiC/GaN inverter applications. |
| Failsafe Output State | Outputs enter high-impedance on VDD1/VDD2 undervoltage - prevents false triggering of power stage during startup or fault conditions. |
| Low Propagation Delay | 12 ns (typ) with <1 ns channel-to-channel skew - supports tight-timing PWM feedback and encoder synchronization. |
Applications
| Industrial PLC Digital I/O Modules | Motor Drive Gate Driver Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si8620ED-IS | 2-channel unidirectional, 100 Mbps, 5 kVRMS reinforced isolation, but uses capacitive coupling with different CMTI spec (±75 kV/µs). | Lower CMTI margin may require additional layout mitigation in high-noise SiC inverter gate drive zones. | Preferred where VDE 0884-11 certification is not mandated and cost sensitivity outweighs extreme noise immunity needs. |
| ISO7721DWR | 2-channel unidirectional, 100 Mbps, 5 kVRMS reinforced isolation, but rated only to 105°C max ambient and lacks failsafe high-Z output. | Not suitable for extended-temperature industrial enclosures or safety-critical fail-safe gate drive enable paths. | Appropriate for commercial-grade automation controllers operating within standard temperature ranges and non-failsafe architectures. |
Compared with Si8620ED-IS and ISO7721DWR, the CS8101YTHA5G delivers superior noise immunity (±100 kV/µs CMTI) and guaranteed failsafe behavior on supply loss-critical for functional safety in motor drives and solar inverters where unintended power device activation must be prevented.

FAQ
What is the maximum data rate supported by the CS8101YTHA5G?
The CS8101YTHA5G supports a maximum data rate of 100 Mbps under specified operating conditions (VDD = 3.3 V or 5 V, TA = 25°C). This performance is maintained across its full temperature range (–40°C to +125°C) with typical propagation delay of 12 ns and channel-to-channel skew below 1 ns, making CS8101YTHA5G suitable for high-speed SPI, PWM, and encoder signal isolation in real-time control systems.
Does the CS8101YTHA5G provide failsafe behavior during power loss?
Yes, the CS8101YTHA5G enters a high-impedance (Hi-Z) output state when either VDD1 or VDD2 falls below its respective UVLO threshold. This failsafe behavior prevents unintended activation of downstream gate drivers or logic circuits during brown-out, startup, or supply sequencing faults-ensuring safe operation in motor drive and power converter applications where CS8101YTHA5G is deployed.
What isolation certifications does the CS8101YTHA5G meet?
The CS8101YTHA5G is certified for reinforced isolation per UL 1577 (5 kVRMS, 1 minute) and VDE 0884-11 (5 kVRMS, partial discharge <5 pC). It also meets IEC 61000-4-2 (±8 kV contact ESD), IEC 61000-4-4 (±2 kV EFT), and IEC 61000-4-5 (±4 kV surge) immunity standards-making CS8101YTHA5G compliant for use in industrial environments requiring functional safety and EMC robustness.
Can the CS8101YTHA5G operate with mixed supply voltages on each side?
Yes, CS8101YTHA5G supports independent 3.0–5.5 V supplies on VDD1 and VDD2, enabling mixed-voltage operation-for example, interfacing a 3.3 V MCU input side with a 5 V gate driver output side. The device maintains full 100 Mbps data rate and CMTI performance across all valid supply combinations, and no level-shifting circuitry is required when using CS8101YTHA5G in such configurations.
What is the creepage and clearance distance of the CS8101YTHA5G package?
The CS8101YTHA5G uses an SOIC-8 wide-body (SO-8WB) package with minimum creepage and clearance distances of 8.3 mm, satisfying reinforced isolation requirements for pollution degree III per IEC 60664-1. This physical spacing, combined with its internal SiO₂ dielectric barrier, enables CS8101YTHA5G to achieve 5 kVRMS isolation rating without requiring additional PCB slotting or conformal coating in most industrial layouts.
