Pickering Electronics, a company with experience in miniaturizing and enhancing reed relay performance, has expanded its single-in-line Series 104 reed relay family to include a version with a 5kV standoff and up to 1.5kV switching. Previously, achieving a 5kV standoff rating required a larger, non-SIP (Single-in-Line-Package) relay. Four of the new 104 5D parts can now fit into the same PCB area previously occupied by one larger relay while maintaining space between adjacent parts.

The Series 104 reed relays are suitable for various applications, including mixed-signal semiconductor testers, cable testing, photovoltaic efficiency monitoring, electric vehicle and charge point testing, mining gas analysis, medical electronics, in-circuit test equipment, high voltage instrumentation, and more. The 5kV devices are available in 1 Form A (SPST N.O.) configuration, with 5, 12, or 24V coils and optional internal diode protection.

For applications requiring extended operating temperature ranges, the 104HTs are designed to operate from -40 °C to +125 °C, with custom versions available for temperatures up to +150 °C. The 104 5kV version expands Pickering’s high voltage relay range, covering 1kV to 15kV.

Some of the key features of the reed relay include:

  • Standard 5, 12, and 24 Volt coils, with optional internal diode
  • Compact size, stackable H.V. isolation reed relays on 0.25″ pitch
  • Up to 5000 V standoff, 1500 VDC switching
  • 104HT operates between -40°C and +125°C, with up to +150°C as an additional option
  • 1ms operating speed
  • 100% dynamic contact resistance testing

Commented Kevin Mallett, Technical Specialist at Pickering Electronics: “This is the first miniature SIP reed relay with a standoff of up to 5kV and up to 1.5kV switching, and so is particularly advantageous where a compact design is essential, as the devices can stack at just 6.35mm. Despite its size, the relay maintains reliable performance, ensuring that high voltage switching or control operations can be conducted effectively and safely.”
