New high voltage surface mount reed relays from Pickering Electronics can switch up to 1kV

Relay series also offers voltage isolation of up to 3kV switch stand-off

Leading high-performance reed relay manufacturer, Pickering Electronics has announced its Series 219 high voltage surface mount reed relays at productronica, the world’s leading trade fair for the electronics manufacturing industry. Available in multiple package types (of the same size, but with differing pin positions), these high voltage surface mount reed relays can switch up to 1000V in 1 Form A (SPST), 2 Form A (DPST), and 1 Form B (SPNC) contact configurations; switch stand-off is up to 3000V, while switch-coil isolation is up to 5000V stand-off.

Series 219 surface mount reed relays are ideal for a range of high voltage applications, including mixed-signal semiconductor testers, medical equipment testing, EV (electric vehicle) charge point testing, and monitoring solar cell photovoltaic efficiency.

Series 219 reed relays also offer all contact configurations with three coil voltages, 3V, 5V, or 12V. Switch stand-off is up to 1.5kV in the 2 Form A package, up to 2kV in 1 Form B, and up to 3kV in the 1 Form A package, while switch-coil isolation is up to 5kV stand-off in 1 Form A and 1 Form B types. Switching is up to 0.7A and 10W, while the operating temperature range spans from -40°C to +105°C. All part numbers are also offered with a diode option.

“Only Pickering makes surface mount high voltage relays with 2 Form A and 1 Form B packages,” observed Kevin Mallett, Technical Specialist at Pickering Electronics. “And as customers might expect, our Series 219 Reed Relay is available with several standard build options to tailor it to your specific application. If your requirements can’t be met by either a standard relay or any of the standard build options, we also offer a customized reed relay service to suit your specific application.”

In common with other relays produced by Pickering, the new 219 Series high voltage reed relays use the very best instrument-grade switches with appropriate switch blade coatings for the currents and voltages demanded by the application. Another innovation – still not employed by some competition – is SoftCenter™ technology that minimizes internal stresses on the reed switch, resulting in an extended life and contact resistance stability. The use of magnetic Mu-Metal shielding and electrostatic screening prevents faulty operation.
