Littelfuse P-1U-L Multiport SIDACtor Protection Thyristors

Littelfuse P-1U-L Fixed Voltage Multiport SIDACtor Protection Thyristors are designed to protect sensitive Subscriber Line Interface Circuit (SLIC) devices from damaging overvoltage transients. The P-1U-L Series from Littelfuse provides a high surge current rated dual port protection solution incorporating a fixed voltage switching threshold for negative surges. All positive surges are routed through an internal diode to a ground reference. These thyristors can replace four discrete components offering low voltage overshoot and a low on-state voltage. The components are lead-free, halogen-free, and RoHS compliant.

Features

  • Low voltage overshoot
  • Low on-state voltage
  • Does not degrade surge capability after multiple surge events within limit
  • Fails short circuit when surged in excess of ratings
  • Two-port protection
  • Integrated diodes for positive voltage surges
  • Replaces four discrete components
  • 2nd level interconnect is Pb-Free per IPC/JEDEC J-STD-609A.01
  • Lead-free, halogen-free, and RoHS compliant
