A new set of transient voltage suppressors from ProTeck Devices is said to deliver circuit protection in 28-volt aircraft applications and for induced lightning on rural transmission lines.
TEMPE, Ariz.—ProTek Devices reported that it introduced a new set of transient voltage suppressors (TVS) primarily for 28-volt aircraft circuit protection applications, such as DC power supply protection.
The PAL704-P15K36 and PAL704-P15K36T transient voltage suppressors are 15-kilowatt silicon TVS devices. They meet standards compliance for MIL-STD-704 and MIL-STD-19500, in addition to being RTCA DO-160G standards compliant, according to a release from ProTek Devices.
These assemblies typically operate with a minimum source impedance of 0.25 Ohms and have a peak pulse power rating of 15,000 watts for a 1 MS waveshape. Therefore, they can also be used in applications where induced lightning on rural or remote transmission lines presents a hazard to electronic circuitry, the release stated.
The PAL704-P15K36 TVS is designed for high current, short peak pulse transient applications. The PAL704-P15K36T is designed for extended peak pulse transients greater than one millisecond. Each device is 100 percent tested, according to ProTek.
Both TVS devices are available in a molded plastic case. The PAL704-P15K36 has an approximate weight of 30 grams, and the PAL704-P15K36T has an approximate weight of 48 grams. Both parts also have a flammability rating of UL 94V-0. The operating and storage temperature is -55 to 150 degrees Celsius.
More technical specifications can be found on the company’s data sheet that is available online, the company said.
ProTek Devices™ is a privately held semiconductor company that offers what it described as “a comprehensive product line of circuit protection devices.” Companies use these devices to deliver enhanced safety and to protect investments they make in their electronics designs, across industrial to consumer products.
The company’s circuit protection components include transient voltage suppressors (chipscale TVS arrays and EMI filter / TVS arrays), TVS diode arrays, steering diodes and steering diode hybrid arrays, thyristor surge suppressors, and high-powered components and modules.
ProTek’s components are used worldwide to guard against various electric transient surges and high voltage spikes that can damage electronics investments. These applications are reported to include aerospace subsystems, automotive subsystems, computing interfaces, consumer electronics, industrial and instrumentation equipment, medical devices, military subsystems, and networking and telecommunications equipment.
According to ProTek, its devices provide circuit protection against lightning; electrostatic discharge (ESD); electrical fast transients (EFT), nuclear electromagnetic pulses (NEMP); inductive switching; electromagnetic interference / radio frequency interference (EMI / RFI), and more.
