81RIA40 Overview

The rated average on-state current (A) is the maximum repeated average of forward current, which is 80.The RMS on-state current must be maintained below 125 A to ensure normal operation.In this device, the repetitive peak off-state voltage is 400 V. This is the maximum voltage allowed across the device.The maximal repetitive reverse voltage (Vrrm) is the maximum voltage that a diode can sustain in reverse-bias mode.In electrical, electromagnetic, and electronic devices, the holding current (hypostatic) is the minimum current needed for an electronic or electrical device to remain on.On-state voltage (V) should be 1.6@250A during normal operation.The gate trigger current is the gate current required to switch a device from an off (Blocked) state into an on (On). This device has a DC gate trigger current-Max of 120 mA.SCRs have a surge current rating of 1990, which defines the maximum non-repetitive or surge current they can handle for a limited time during their existence.Repetitive peak reverse voltages are the maximum instantaneous reverse voltage included in all repetitive transient voltages, and their voltages are ideally 400.This device's RMS on-state current (A) 125 represents the maximum rms current allowed in a specified case temperature.
