SI82B40BEC-ISR

Isolators - Gate Drivers Overview

The SI82B40BEC-ISR is a single-channel isolated gate driver from the Skyworks SI82 series. It features a 3.75 kVrms isolation rating and delivers a peak output current of 6 A. The device operates within a supply voltage range of 3 V to 20 V and supports both inverting and non-inverting configurations. Key electrical parameters include a maximum propagation delay of 63.1 ns, rise time of 8.3 ns, and fall time of 8.6 ns. It utilizes CMOS logic and includes a shutdown function. The component is housed in an 8-pin SOIC package and functions over a temperature range of -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• Provides high-voltage galvanic isolation for safe signal transmission between control and power stages
• Delivers strong drive capability with 6 A peak output current for efficient switching
• Supports flexible logic configuration with independent inverting and non-inverting outputs

Isolators - Gate Drivers Applications

• Industrial motor drives requiring high isolation voltage
• Inverter circuits in renewable energy systems
• High-power solid-state relay control interfaces

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'ISR' corresponds to the 8-pin SOIC package variant when sourcing. Confirm that the 3.75 kVrms isolation rating meets the safety requirements of the target application. Ensure compatibility with the required operating temperature range of -40°C to +125°C. Check for RoHS compliance status as indicated in official documentation before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel driver with 6 A output current is required. Choose this part if the application demands 3.75 kVrms isolation rather than higher ratings found in other series members. Consider the 63.1 ns propagation delay for timing-sensitive designs. Verify that the SOIC-8 footprint fits the PCB layout constraints compared to SSO-8 alternatives.

Isolators - Gate Drivers Part Context

This device belongs to the Skyworks SI82 family of capacitive coupling isolated gate drivers. It shares architectural similarities with models like SI82B40BBE-IS4 but differs in isolation voltage and package type. The SI82 series is designed to replace bulky magnetic isolators in modern power electronics, offering smaller form factors and improved reliability through silicon-based isolation technology.

Isolators - Gate Drivers Replacement Considerations

SI82B40BBE-IS4 offers similar functionality but provides 6 kV isolation and uses an SSO-8 package. SI82A40BGC-ISR provides lower 1 A output current with 3.75 kV isolation. Verify pinout compatibility and thermal performance when substituting these variants.
