Microchip Introduces 3 kW Transient Voltage Suppressor Diode Array Family for Superior Circuit Protection in Harsh Environments

4 min read

To be certain crucial functions, aviation and house methods rely on electronic and logic functionality and circuitry in engine regulate units, environmental controls, devices and actuators. Knowledge facilities, the 5G infrastructure and interaction methods also rely on sophisticated circuitry demanding protection. Each and every system should operate repeatedly in spite of voltage surges and spikes from lightning, solar situations and electromagnetic incidents. Microchip Technologies Inc. (Nasdaq: MCHP) today announced its freshly-expanded portfolio of Transient Voltage Suppressor (TVS) vertical arrays – the MDA3KP Transient Voltage Suppressor (TVS), a 3 kW diode loved ones of a lot more than 25 items with diverse screening amounts, polarities and qualification standards.

Microchip’s MDA3KP TVS diode array loved ones – the only accessible technological know-how featuring a detailed voltage assortment tested to a large trustworthiness normal and qualified primarily based on the MIL-PRF-19500 JANTX degree equivalence normal – delivers an integrated multi-diode alternative. These voltage-clamping devices offer speedy-reacting Avalanche Breakdown Diode (ABD) options that divert excess current about delicate elements to defend them from electrical overstress.

“Digital controls, logic and diagnostic system circuit blocks require highly dependable, secure current and electric power protection to be certain functions in extreme environments,” mentioned Leon Gross, vice president of Microchip’s Discrete Products Team business device. “This diode loved ones also addresses the difficulties system designers face with a a lot more productive vertical building and need for significantly less board house than other devices.”

MDA3KP TVS diode arrays are accessible in the next screened version industry standards: M, MA, MXL and MX. The devices have been exposed to various amounts of screening to be certain they meet up with the aircraft lightning protection prerequisites established forth in the normal for environmental screening of avionics, RTCA DO-160G (Lightning Induced Transient Susceptibility). RTCA is the industry consortium that develops consensus on crucial aviation modernization issues.

The MDA3KP TVS diode array, a vertically created 8-diode, sixteen-pin area mount bundle, will allow for productive structure and relieve of structure, as significantly less printed circuit board house is essential when enabling better electric power densities. In the MDA3KP TVS diode array loved ones, each individual device’s vertical building delivers the electric power of eight smaller sized devices on a printed circuit board, removing the have to have for the multiple devices even as it delivers better electric power.

Obtainable in unidirectional and bidirectional building in standoff voltages of 6V to 40V, the elements offer Electrostatic Discharge (ESD) and Electrical Quick Transients (EFT) protection in accordance IEC standards and a Peak Pulse Electric power ranking of 3000 W at 10/a thousand µs. With an prolonged temperature assortment from -55°C to +150°C, the devices are whole lot traceable, surge tested, and Humidity Sensitivity Degree (MSL) Degree 1 – demonstrating that these devices are completely ready for use in harsh environments. MSL signifies that no dry pack or bake is essential prior to use. The MDA3KP TVS diode array family’s electric power ranking is the industry’s only accessible technological know-how with this degree of screening in this bundle.

Microchip’s 3 kW MDA diode loved ones delivers military system circuit protection for ruggedized handheld radios, the International Positioning System (GPS) and interaction take a look at products. Other system apps include things like automotive, industrial logging products, electric power materials and marine methods.
