SIL HV reed relays

From Meder comes the miniature SIL HV series of high-voltage and high-current reed relays that can switch up to 1000V and carry up to 5A, in an epoxy sealed, single-in-line package measuring only 24mm x 6.4mm x 8.9mm.

An optional offset pin-out measuring 29mm x 6.4mm x 8.9mm is also available. Standard coil selections include 5V or 12V with or without diode suppression.

This series can switch up to 1000V and carry up to 5A for up to 50ms at a consistent repetition rate or 10A at pulsed current for up to 10?s. The relays can dielectrically hold off up to 4000V across the contacts as well as between contacts and coil.

The SIL HV series is especially suitable for use in automatic test systems, testing high power MOSFETs. These rugged semiconductors have very high initial peak current capability and require a reed relay that can carry high current pulses for hundreds of millions of operations.

These relays come standard with an internal magnetic shield making them a suitable choice for close stacking matrices.

Due to their small size, high current and high voltage capability, the SIL HV Relays are also an appropriate match for several medical device applications such as portable defibrillators. These reed relays are RoHS-compliant and UL approved.
