Pickering Electronics has developed the first 1.5kV reed relay in a Single-in-Line-Package (SIP) with a stand off voltage of 5kV.
Previously, to achieve a 5kV stand-off rating in a reed relay, a larger, non-SIP relay was required. Four of the new 104 5D parts can now fit the same PCB area that one larger style occupied, even with sufficient clearance space between adjacent parts.

“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,” said Kevin Mallett, Technical Specialist at Pickering Electronics.
Pickering aims the Series 104 reed relays at mixed signal semiconductor testers, cable testing, monitoring photovoltaic efficiency, EVs & charge point testing, mining gas analysis, medical electronics, in-circuit test equipment, high voltage instrumentation, and much more. 5kV devices are available in 1 Form A (SPST N.O), and 5, 12 or 24V coils with optional internal diode protection.
Where extended operating temperature ranges are required, 104HTs are designed to work from -40 °C to +125 °C, or custom versions are available up to +150 °C.
The 104 5kV version fills the gap in Pickering’s expanding high voltage reed relay range, which spans between 1kV to 15kV.
