Miniature HV reed relay from Pickering Electronics at the heart of On Semi IC test system
14 July 2020
Custom request for On Semiconductor ATE test system becomes industry’s smallest high voltage (HV) reed relay.
Reed relay specialist, Pickering Electronics has developed a miniature high voltage relay for use in a new IC (integrated circuit) test rig, designed by chip maker, ON Semiconductor.
In switching systems for test & measurement applications, reed relays are often the best solution thanks to their small size, high isolation resistance, hermetically sealed contacts, fast operate time and long-life expectancy. When developing a new test rig, ON Semiconductor – a long-standing customer of Pickering - identified the need for a reed relay with a stand-off voltage of at least 400VDC, which was also small enough to meet its demanding high switching density requirements.
The internal clearance constraints required by the uprated specs would not fit within the package dimensions of other miniature relays in Pickering’s broad portfolio. However, in just seven weeks, Pickering was able to send first prototypes of a device housed in the mini-SIP package with a footprint of 12.5mm x 3.7mm and a height of 6.6mm able to deliver a minimum stand-off of 1500V.
Keith Moore, Pickering CEO comments: “Because Pickering has all elements of relay design and manufacture in house, we are able to respond quickly and effectively to custom requests such as this. In this instance, as so many previously, a special design leads to a new standard product, and so we now offer Series 131 devices – industry’s smallest high voltage reed relays.”
Featuring a choice of 3, 5 or 12 volt coils, with optional internal diode, Series 131 reed relays are available in the 1 Form A (energize to make) SPST N.O. configuration, and can switch up to 0.7 amps, 10 watts. Devices are ideal for cable testers, mixed signal/semiconductor testers, backplane testers, high voltage instrumentation, in-circuit test equipment and other HV applications.
Pickering Electronics also manufactures various other miniature high voltage SIL/SIP reed relays. Series 119 types deliver a stand-off voltage performance of up to 3kV on a footprint of 15.1 x 3.7mm (1 Form A) and a profile of 6.6mm, while Series 104s offer the same high voltage performance but with a higher switching power of up to 25W and a higher coil resistance of up to 3000? in a package measuring 24.1 x 6.3 x 8.2mm (1 Form A).
About Pickering Electronics
Pickering Electronics was formed over 50 years ago to design and manufacture high quality reed relays, intended principally for use in instrumentation and test equipment. Today, Pickering's Single-in-Line (SIL/SIP) range is by far the most developed in the relay industry with devices 25% the size of many competitors. These small SIL/SIP reed relays are sold in high volumes to large ATE and Semiconductor companies throughout the world.
Pickering Electronics is part of the privately-owned Pickering Group, made up of three electronics manufacturers, including Pickering Interfaces who design and manufacture modular signal switching and simulation products, and Pickering Connect who design and manufacture cables and connectors.
