Why Semiconductor Test Engineers Keep Choosing Reed Relays The semiconductor industry moves fast — new process nodes, new chip architectures, new test challenges every quarter. But one component has stubbornly refused to become obsolete: the reed relay. In an era of solid-state multiplexers, RF MEMS switches, and software-defined test architectures, the humble reed relay remains…

DC fast charging stations push 200–1000V DC at up to 500A. Before current flows, the charger must verify that the vehicle-to-charger insulation resistance exceeds safety thresholds—typically >500Ω/V per IEC 61851. This verification relies on precision high-voltage reed relays that can switch measurement circuits at full bus voltage without introducing leakage paths or contact bounce. In…
