Designers of voltage regulators, inrush current limiters for SMPSs, motor-control circuits, and industrial solid-state relays can improve the reliability of their applications and/or reduce costs by using smaller heatsinks. This is possible with the new high-temperature Silicon Power Switches from STMicroelectronics.

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

“Addressing a wide range of industrial and two- and three-wheel vehicle applications, ST’s high-temperature SCRs are particularly well suited to voltage regulators in markets where cost efficiency and high reliability are key requirements”, the firm stated in the announcement.

By offering tight control of the gate triggering current, the new SCRs offer improvements in the reliability of the end products. They are also said to be more gate-sensitive compared with previous generations, while offering high electrical noise immunity.

Some 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, and availability in various power packages, with UL 1557-certified insulated packages withstanding up to 2500 VRMS.

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.
