SGM40666BS Datasheet High-current Over-voltage Protector

Manufacturer: SG Micro

Overview: SGM40666AS/SGM40666BS High-Current Over-Voltage Protector GENERAL.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The SGM40666AS and SGM40666BS are over-voltage protection devices designed to protect low voltage systems from damage with a high voltage supply up to +31VDC and +40VPEAK (10s with 50mA current limit).

The SGM40666AS withstands +90V/-400V while the SGM40666BS can also withstand surges up to +80V/ -400V without damage.

The integrated 27mΩ (TYP) RON FET allows it to pass through 4.5A continuous current.

Key Features

  • Wide Power Supply Voltage Range: 2.5V to 28V.
  • Input Voltage up to 40V with 50mA Current Limit for 10s Duration.
  • Integrated Switch On-Resistance: 27mΩ (TYP).
  • Wide Adjustable OVLO Threshold Range: 4V to 22V.
  • Internal Over-Voltage Protection Threshold: 6.79V (TYP).
  • Surge Immunity.
  • SGM40666AS: Up to +90V/-400V Surge Immunity.
  • SGM40666BS: Up to +80V/-400V Surge Immunity.
  • 32.3V Clamping Circuit Trigger Threshold when Rising Slope > 4.5V/μs (SGM40666AS).
