SI82395BD-ISR

Isolators - Gate Drivers Overview

The SI82395BD-ISR is a dual isolated gate driver from the Si8239x series, manufactured by Skyworks Solutions Inc. It features two independent channels in a single package with up to 5 kVRMS isolation and 1500 VDC peak differential voltage. The device operates within a temperature range of -40°C to +125°C and utilizes a 16-SOIC (Wide) surface-mount package. Key electrical parameters include a maximum propagation delay of 40 ns, rise and fall times of 12 ns, and an output current capability of 4 A. It supports TTL logic inputs and includes an 8 V undervoltage lockout (UVLO). The component is AEC-Q100 qualified for automotive applications.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation between input and output circuits using capacitive coupling technology.
• Features high electromagnetic immunity suitable for industrial environments.
• Includes integrated undervoltage lockout to prevent improper switching during low supply conditions.

Isolators - Gate Drivers Applications

• Automotive power electronics systems
• Industrial motor drives
• Inverter control circuits

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'ISR' corresponds to the reel packaging format rather than just the tube configuration listed in some general databases. Confirm the 16-SOIC wide body dimensions match your PCB footprint requirements. Ensure the AEC-Q100 qualification status meets your specific automotive grade standards if applicable.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel isolation is required in a compact form factor. The 4 A peak output current supports driving medium-power MOSFETs or IGBTs. Consider the 12 ns transition speeds for high-frequency switching applications. Verify that the 5 kVRMS isolation rating exceeds the system's working voltage requirements.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of digital isolators. It replaces older transformer-based or optocoupler solutions by offering higher reliability and lower power consumption. The dual-channel design allows for synchronized control of half-bridge or full-bridge configurations while maintaining safety isolation barriers.

Isolators - Gate Drivers Replacement Considerations

Check for direct pin-compatible alternatives within the Si8239x series that may offer different isolation voltages or package options. Verify that any substitute maintains the same 4 A output drive strength and 5 kVRMS isolation rating to ensure circuit compatibility.
