Dual Programmable Thyiristor Transient Voltage Suppressor

This device has been specially designed to protect 2 new high voltage, as well as classical SLICs, against transient overvoltages. Positive overvoltages are clamped by 2 diodes. Negative surges are suppressed by 2 thyristors, their breakdown voltage being referenced to –VBAT through the gate. This component presents a very low gate triggering current in order to reduce the current consumption on the printed circuit board during the firing phase. These devices are not subject to aging and provide a fail-safe mode in a short circuit for better protection.

Features

  • Dual Voltage-Tracking Protectors ；
  • wide negative pressure range：VMGL=-170VMAX
  • low dynamic switching voltage：VFP and VDGL
  • low gate triggering current ：IGT=5mAMax
  • Peak Pulse Current：IPP=40A（10/700µs）
  • high Holding current ：IH≥150mA

Application

  • UP61089Q are designed to protect communication equipment such as SPC exchanger from damaging overvoltage transients in the second level.
