Description and Introduction

TO-92 SIDACtor solid state protection devices protect telecommunications equipment such **Introduction to the P3500EAL by LITTELFUSE**  

The **P3500EAL** is a high-performance electronic component designed by LITTELFUSE, offering reliable overcurrent protection in a compact form factor. As part of the PICO® 259 series, this resettable polymeric positive temperature coefficient (PPTC) device is engineered to safeguard circuits from excessive current and short-circuit conditions.  

With a **hold current of 3.5A** and a **trip current of 7A**, the P3500EAL provides precise protection while maintaining low resistance in normal operation. Its resettable functionality ensures minimal downtime, making it ideal for applications where frequent maintenance is impractical. The device operates within a **voltage range of up to 30V**, catering to a variety of low-voltage electronic systems.  

Common applications include **consumer electronics, power supplies, and automotive systems**, where stable and dependable overcurrent protection is critical. The P3500EAL’s compact SMD package enhances design flexibility, allowing seamless integration into space-constrained PCBs.  

LITTELFUSE’s commitment to quality ensures that the P3500EAL meets stringent industry standards, delivering consistent performance under demanding conditions. Whether used in industrial controls or portable devices, this PPTC device offers a robust solution for circuit protection needs.

Alternative Part Number

  • TISP3500T3BJ --: Thyristor surge protector with similar 350V breakover rating, direct functional replacement for the SIDACtor-style device.
  • P3500SCLRP --: Same manufacturer SIDACtor family with comparable 350V breakover voltage and surge current capability.
  • TISP4350T3BJ --: Bourns thyristor surge suppressor rated near 350V, suitable alternative with similar clamping behavior.
  • TISP3500T3BJ --: Thyristor surge protector with similar 350V breakover rating and TO-220 package, direct functional replacement for telecom protection.
  • P3100EAL --: Same SIDACtor EAL series family with slightly lower breakover voltage, same package and pinout, easy drop-in with minor voltage margin change.
  • TISP4350T3BJ --: Bidirectional thyristor surge suppressor rated near 350V, suitable alternative for overvoltage protection in telecom and industrial lines.
