Microchip introduces 3kW transient voltage suppressor diode array family

Microchip has expanded its portfolio of Transient Voltage Suppressor (TVS) vertical arrays. The MDA3KP Transient Voltage Suppressor (TVS), is a 3kW diode family of more than 25 products with different screening levels, polarities and qualification standards.

The MDA3KP TVS diode array family provides an integrated multi-diode solution. These voltage-clamping devices provide fast-reacting Avalanche Breakdown Diode (ABD) features that divert excess current around sensitive components to protect them from electrical overstress.

These diode arrays are available in the following screened version industry standards: M, MA, MXL and MX. The devices have been exposed to various levels of testing to ensure they meet the aircraft lightning protection requirements set forth in the standard for environmental testing of avionics, RTCA DO-160E (Lightening Induced Transient Susceptibility).

The MDA3KP TVS diode array, a vertically constructed 8-diode, 16-pin surface mount package, allows for efficient layout and ease of design, as less printed circuit board space is required while enabling higher power densities. Each device’s vertical construction provides the power of eight smaller devices on a printed circuit board, eliminating the need for the multiple devices even as it provides higher power.

Available in unidirectional and bidirectional construction in standoff voltages of 6V to 40V, the components provide Electrostatic Discharge (ESD) and Electrical Fast Transients (EFT) protection according IEC standards and a Peak Pulse Power rating of 3000 W at 10/1000 µs.

With an extended temperature range from -55°C to +150°C, the devices are lot traceable, surge tested, and Moisture Sensitivity Level (MSL) Level 1 – demonstrating that they are ready for use in harsh environments. MSL indicates that no dry pack or bake is required prior to use. The MDA3KP TVS diode array family’s power rating is the industry’s only available technology with this level of screening in this package.

Microchip’s 3kW MDA diode family provides military system circuit protection for ruggedized handheld radios, the Global Positioning System (GPS), and communication test equipment. Other device applications include automotive, industrial logging equipment, power supplies and marine systems
