This Sxx08x SCR series is ideal for uni-directional switch applications such as phase control, heating, motor speed controls, converters/rectifiers and capacitive discharge ignitions.

These SCRs have a low gate current trigger level of 0.2 to 15 mA at approximately 1.5V, with a sensitive version of this series having a gate trigger current less than 500µA. The sensitive gate SCR version is easily triggered by sense coils, proximity switches, and microprocessors.

Features & Benefits:

  • Electrically isolated "L-Package" is UL recognized for 2500Vrms
  • Glass – passivated junctions
  • Voltage capability up to 1000 V
  • Surge capability up to 100 A at 60 Hz half cycle
  • Halogen free and RoHS compliant

Applications:

Typical applications are capacitive discharge systems for strobe lights, nailers, staplers and gas engine ignition. Also AC control & rectification for power tools, home/brown goods and white goods appliances and 2-wheeler rectifier/ battery regulator.

Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage.
