ST’s New High-Temperature Silicon Power Switches Enhance Reliability in Motorcycles and Industrial Applications

High-Temperature Silicon Power Switches

High-temperature Silicon-Controlled Rectifiers (SCRs) address a wide range of industrial and two- and three-wheel vehicle applications.

STMicroelectronics to now leverage manufacturers of voltage regulators, inrush current limiters for switch-mode power supplies, motor-control circuits, and industrial solid-state relays to improve the reliability of their applications and/or reduce costs by using smaller heatsinks.

The latest High-temperature Silicon-Controlled Rectifiers (SCRs) touts to address a wide range of industrial and two- and three-wheel vehicle applications.

ST’s high-temperature SCRs are sought to be well suited to voltage regulators in markets where cost efficiency and high reliability are key requirements.

Operating with junction temperatures of up to 150oC, the TN4015H SCRs offer on-state RMS current ratings of 40A, extending and complementing the existing 12A – 20A product range.

They are designed to offer tight control of the gate triggering current, leading to enhanced reproducibility on the customers’ assembly lines with corresponding improvements in the reliability of the end products.

The new SCRs are also more gate-sensitive compared with previous generations, while delivering best-in-class electrical noise immunity.

Other key technical features include:

  • High noise immunity (dV/dt up to 1000V/μs);
  • 600V blocking voltage;
  • High turn-on current rise (dI/dt = 100 A/μs);
  • ECOPACK2 packaging for compliance with safety regulations and faster certification;
  • Available in various power packages, with UL 1557-certified insulated packages withstanding up to 2500 VRMS.

Availability, Pricing and Packaging

The TN4015H 40A SCRs are available now in volume production in D2PAK, TO-220AB, and TO-220AB insulated packages, priced from $0.507 for 1,000 unit orders.
