New MADP-009989 Diode is Offered in Thermally-Matched Configuration

Press Release Summary:

Richardson’s MADP-009989 Diode is available in surface mount or axial lead package with ultra-low magnetic construction. The unit is designed for protecting MRI receivers from high energy fields, long RF pulses and RF spikes. The diode features capacitance and conductance of 1.2 pF and 40 µs at 0 V bias respectively. The MADP-009989 acts as a passive protector for the MRI receiver.


Original Press Release:

Richardson RFPD Introduces New Fast MRI Protection Diode from MACOM

MADP-009989 designed to protect MRI receivers from high RF energy fields

July 31, 2018 – Geneva, Ill.: Richardson RFPD, Inc. announced today the availability and full design support capabilities for a new diode for MRI applications from MACOM Technology Solutions Inc.

The MADP-009989 diode was designed to protect MRI receivers from high RF energy fields, including long RF pulses and RF spike pulses present in most MRI machines. This diode acts as a passive protector (limiter) for the MRI receiver. No forward bias voltage is required to turn-on the diode. It is self-biased by the RF transmitter pulse power. A switch driver is not needed for this receiver protection application.

The new diode is available in two package configurations for flexibility in design. It is ideally suited for MRI receiver protection and body coil isolation applications.

Additional key features of the MADP-009989 include:

  • Package configuration options: surface mount, axial lead
  • Passivated chip
  • Ultra-low magnetic construction
  • Non-cavity design
  • Thermally-matched configuration
  • Low capacitance @ 0 V bias: 1.2 pF (typical)
  • Low conductance @ 0 V bias: 40 µs (maximum)
  • Compatible with automatic insertion equipment
