UMX1089 Datasheet Low Loss Mri Protection Diodes

Manufacturer: Microsemi (now Microchip Technology)

Overview: UMX1089 LOW LOSS MRI PROTECTION DIODES ® RoHS pliant GENERAL.

General Description

The UMX1089 diode series was designed to protect MRI receivers from high RF energy fields including long RF pulses and RF spike pulses present in most MRI machines.

The UMX1089 acts as a passive protector (limiter) for the MRI receiver.

No forward bias voltage is required to turn on the diode.
