The Littelfuse P2T750E is a SIDACtor® protection thyristor designed to protect sensitive telecommunications equipment from damaging overvoltage transients. As a solid-state protection device, it provides a fast and reliable means of diverting surge currents away from sensitive circuitry.

Applications:

• Central Office Equipment
• Customer Premises Equipment (CPE)
• Data Line Protection
• Telecom Line Cards
• Modems and Routers
• Analog and Digital Subscriber Line (ADSL/VDSL) equipment

Features:

• Low voltage overshoot
• Eliminates voltage overshoot caused by capacitive loading
• High surge current capability (I<sub>TSM = 750 A)
• Low on-state voltage
• Does not degrade after multiple surge events
• Fails short circuit when surged in excess of its rating
• RoHS Compliant

Benefits:

• Provides dependable protection against overvoltage transients, safeguarding equipment and minimizing downtime.
• The minimal voltage overshoot characteristic ensures that sensitive components are not subjected to harmful voltage levels during surge events.
• The high surge current capability allows the device to withstand substantial surge events, providing robust protection.
• Maintains consistent protection performance throughout its operational life, even after repeated surge events.
• Offers a safe and predictable response to extreme surge conditions by failing short circuit, preventing further damage to the protected circuit.
