New 3kA SIDACtor Thyristor Collection For Excessive-Energy Density Purposes


Excessive-power density packaging reduces the required printed circuit board area by roughly 50%.

SIDACtor DO_214AB Hi_Res

Littelfuse, Inc. has unveiled the Pxxx0S3N-A Automotive Grade 3kA SIDACtor Safety Thyristor Collection, now out there within the DO-214AB package deal. This product is engineered to supply strong and reliable high-surge present safety for gear working in difficult environments, simplifying compliance with regulatory requirements for designers.

The distinguishing function of the sequence is its excessive energy density design, able to withstanding surge currents of as much as 3 kA (8/20 µs) and voltages as much as 6 kV whereas sustaining a low clamping voltage. This compact SIDACtor part, conveniently housed within the DO-214AB (SMC) package deal, empowers automotive producers to grasp high-power density designs and improve product miniaturisation in automotive electronics. This achievement marks a departure from the previous, the place reaching such formidable surge rankings necessitated a significantly bigger TO-262 package deal.

Particularly engineered for functions in Battery Electrical Automobiles (BEV) and Plug-in Hybrid Electrical Automobiles (PHEV), the sequence delivers unparalleled transient surge safety for onboard chargers when utilized in tandem with a MOV mixture. By seamlessly integrating this compact SIDACtor into their methods, automotive producers can obtain heightened reliability, robustness, and cost-efficiency in AC energy safety for charging methods. Thyristor Collection provides a bunch of key options and benefits, catering to numerous business segments:

  • Excessive Surge Safety: This sequence is engineered to deal with extreme overvoltage transients, offering gear with strong defence towards high-energy surge occasions of as much as 6 kV / 3 kA whereas sustaining an exceptionally low clamping voltage.
  • Automotive Grade: Designed to excel in harsh and demanding environments, the sequence ensures compliance with the stringent AEC-Q101 customary, assuring flawless performance in automotive functions.
  • Compact Design: Utilizing the DO-214AB package deal facilitates product miniaturisation with out compromising robustness. It additionally aids designers in adhering to rigorous automotive-grade necessities.
  • Versatility: Whereas primarily targeted on the automotive business, notably in BEV and PHEV On-Board Chargers, this SIDACtor sequence displays potential functions throughout the economic and ICT electronics sectors.
  • Enhanced System Reliability: Combining this compact SIDACtor with an MOV for transient surge safety ends in a considerably extra dependable and cost-effective on-board charger system

This compact thyristor has emerged as the popular answer for successfully mitigating extreme transients, particularly in uncovered environments. Its versatility is clear in varied functions, resembling Battery Electrical Automobiles (EV/BEV), Plug-in Hybrid Electrical Automobiles (PHEV), Board Chargers (OBC), charging piles, EV wall chargers, and Vitality Storage Techniques, making it an excellent alternative throughout a spectrum of settings.

This sequence guarantees enhanced safety for EVs and vitality storage, endorsed by Charlie Cai, Director of Safety Semi Product Advertising and marketing, for its versatility and automotive-grade robustness. In comparison with legacy options, which regularly grappled with cumbersome designs vulnerable to degradation over time, the Pxxx0S3N-A SIDACtor sequence stands out. Its compact type issue and surge score make it ideally suited for extremely uncovered functions. Notably, it surpasses the Pxxx0FNL 3 kA SIDACtor sequence within the TO-262M package deal, occupying roughly 50% much less PC board area. The thyristors at the moment are available in tape-and-reel portions of three,000 items.
