The Littelfuse P2T150M is a SIDACtor® protection thyristor designed to protect sensitive telecommunications equipment from damaging overvoltage transients. These devices are robust solid-state components that can withstand high surge currents while providing a very fast response time.

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 = 150 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 reliable protection against overvoltage transients, improving equipment uptime and reducing repair costs.
• The low voltage overshoot characteristic ensures sensitive components are not exposed to damaging voltage levels.
• The high surge current capability allows the device to withstand severe surge events, providing robust protection.
• The non-degrading performance ensures consistent protection over the lifetime of the equipment.
• The short-circuit failure mode provides a safe and predictable response to extreme surge events.

Additional Details:

The P2T150M is typically used in conjunction with other protection components, such as fuses and TVS diodes, to provide comprehensive protection. It features a breakover voltage of around 170V. The device is available in a DO-214AA (SMB) package, suitable for surface mounting. It is designed to meet the stringent requirements of telecommunications equipment protection standards.

The Littelfuse P2T150M SIDACtor is a crucial component for ensuring the reliability and longevity of telecommunications equipment operating in environments prone to voltage surges. Its combination of high surge capability, low voltage overshoot, and robust construction makes it an ideal choice for protecting sensitive circuits.
