Microsemi Intros HUM3002/3003/3004 Series Diodes

Microsemi Corp. (Irvine, CA) announced a new PIN diode series for high-power RF switching applications found in medical MRI systems, antenna and band switching, power supplies, and RF heating. Designated the HUM3002/3003/3004 Series, the new diodes are designed for applications where high isolation, low loss and low distortion are critical, as well as the ability to handle high power. Voltages range from 2kV to 4kV with an RF power handling capability of 40kW.

The new diodes are packaged in an easy-to-mount, modified, non-magnetic, DO-4 structure suitable for MRI systems. Microsemi's exclusive SOGO™ passivation process provides stable high-voltage operation. Surge currents of 150A at a half sine of 8.3ms are handled easily. To prevent arcing, the package design has no internal cavity.
