Product details

Overview

SI8410BD-D-IS from Skyworks Solutions is a single-channel, unidirectional digital isolator with 5 kV_RMS reinforced isolation, 150 Mbps data rate, and selectable low-default fail-safe output mode. It operates from 2.70–5.5 V on both sides, features Schmitt-trigger inputs, and is AEC-Q100 qualified for automotive-grade reliability in isolated power supply feedback loops.

For engineers reviewing the SI8410BD-D-IS datasheet, SI8410BD-D-IS pinout, SI8410BD-D-IS application, or SI8410BD-D-IS equivalent, this page delivers verified specifications, SOIC-16 wide-body package details, timing performance at 150 Mbps, fail-safe behavior during input-side power loss, and direct alternatives for isolated gate drive and ADC interface designs.

Technical Context

The SI8410BD-D-IS implements RF-based on/off keying across a semiconductor isolation barrier-eliminating startup initialization and enabling robust noise immunity without optical degradation. Its architecture supports DC-to-150 Mbps operation with sub-11 ns propagation delay and <0.5 ns channel-channel skew.

It integrates independent UVLO monitors per side (VDD1/VDD2), supports fail-safe default-low output during VDD1 unpowered conditions, and maintains stable timing across –40°C to +125°C at full data rate-enabling use in motor control inverters and isolated SMPS where transient immunity (45 kV/µs CMTI) and precise edge alignment are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
Isolation Rating	5 kV_RMS reinforced insulation per UL 1577, IEC 60747-5-5, and VDE 0884-5-supports 300 V_RMS working voltage in industrial and medical systems.
Data Rate	150 Mbps maximum-enables high-resolution isolated ADC sampling and fast PWM feedback in servo drives.
Propagation Delay	≤11 ns max (typ. 8 ns)-ensures tight timing control in real-time motor control and digital power management.
Supply Voltage Range	2.70–5.5 V on both VDD1 and VDD2-allows interoperability with 3.3 V microcontrollers and 5 V gate drivers without level shifters.
Fail-Safe Mode	Default-low output when VDD1 is unpowered-prevents unintended activation of downstream MOSFETs or IGBTs during power-up/down sequences.
Common-Mode Transient Immunity	45 kV/µs minimum-rejects high dv/dt noise in high-power inverters and EV traction systems.
Operating Temperature	–40°C to +125°C at 150 Mbps-certified for under-hood automotive and industrial ambient environments.

Pinout & Package

SI8410BD-D-IS uses a RoHS-compliant SOIC-16 wide-body package (10.3 mm × 10.3 mm, 2.65 mm height) with creepage/clearance ≥8.3 mm-meeting reinforced insulation requirements for 5 kV_RMS isolation.

Pin/Terminal	Circuit Role	Design Meaning
VDD1	Input-side power supply	Supplies transmitter circuitry; must be bypassed with 0.1 µF capacitor near pin.
GND1	Input-side ground reference	Return path for VDD1; requires low-inductance connection to isolate noise coupling into isolation barrier.
IN	Digital input signal	Schmitt-trigger input accepts 2.0–5.5 V logic; immune to slow-rising edges and EMI.
VDD2	Output-side power supply	Supplies receiver and output driver; independent of VDD1 for true galvanic isolation.
GND2	Output-side ground reference	Isolated return path; must be separated from GND1 by ≥8.3 mm creepage in PCB layout.
OUT	Isolated digital output	50 Ω nominal output impedance-requires controlled-impedance trace termination for >50 Mbps signals.
NC	No-connect pins (pins 3, 4, 5, 6, 11, 12, 13, 14)	Not internally bonded; may be left floating, tied to VDD2, or grounded per layout needs.

Key Features

Feature	Design Value
RF-based isolation architecture	Eliminates LED aging and temperature drift-delivers stable propagation delay and jitter over lifetime and temperature.
Selectably fail-safe output	Low-default state prevents unsafe actuation during brownout or controller reset-critical for IGBT gate drivers.
Ultra-low power at high speed	6.8 mA/channel at 100 Mbps and 5 V-reduces thermal load in densely packed power modules.
Precise timing alignment	0.5 ns channel-channel skew and 2 ns propagation delay skew-enables synchronized multi-channel isolation in servo amplifiers.
AEC-Q100 qualification	Qualified to Grade 1 (–40°C to +125°C) with HTOL and ESD testing-validates suitability for automotive powertrain applications.

FAQ

What is the isolation rating and safety certification of SI8410BD-D-IS?

SI8410BD-D-IS provides 5 kV_RMS reinforced isolation and is certified to UL 1577, CSA Component Notice 5A, VDE 0884-5 (IEC 60747-5-5), and IEC 60601-1, IEC 60950-1, and IEC 61010-1 standards-enabling use in medical, industrial, and automotive end-equipment requiring highest safety integrity.

Does SI8410BD-D-IS require external startup initialization or configuration?

No, SI8410BD-D-IS requires no startup initialization or configuration. It begins transmitting valid data within 40 µs of VDD1/VDD2 reaching UVLO threshold, with outputs following input states immediately after start-up time-simplifying firmware design and eliminating boot dependencies in SI8410BD-D-IS-based systems.

What is the default output behavior of SI8410BD-D-IS during input-side power loss?

SI8410BD-D-IS is ordered with default-low fail-safe mode: when VDD1 is unpowered but VDD2 remains active, the OUT pin is held low. This prevents unintended activation of downstream power switches-ensuring safe shutdown behavior in SI8410BD-D-IS-isolated gate driver circuits.

Can SI8410BD-D-IS operate at 150 Mbps across its full temperature range?

Yes, SI8410BD-D-IS guarantees 150 Mbps operation from –40°C to +125°C ambient temperature, with worst-case propagation delay ≤11 ns and pulse width distortion ≤3.0 ns across that range-validated per datasheet Table 5.2 and Figure 4.10, making SI8410BD-D-IS suitable for real-time automotive and industrial control.

What package type and PCB layout considerations apply to SI8410BD-D-IS?

SI8410BD-D-IS uses a SOIC-16 wide-body package with 8.3 mm minimum creepage/clearance. Layout requires physical separation between GND1 and GND2 traces, 0.1 µF bypass capacitors placed adjacent to VDD1/GND1 and VDD2/GND2 pins, and controlled-impedance routing for OUT if used above 50 Mbps-per SI8410BD-D-IS datasheet Section 4.3.
