MA45471
Dual Anti-Parallel Non-Magnetic PIN Diode
RoHS Compliant
V1
Features
• Designed for MRI applications
• Anti-Parallel Self Bias Arrangement
• Non-Magnetic Surface Mount Package
• SPC Process for Superior Parametric Repeatability
• RoHS Compliant with 260°C reflow compatibility
Description
The MA45471 device acts as a passive switch using
silicon PIN diodes in a surface mount non– magnetic
package. The PIN diode pair are arranged in an
anti-parallel configuration and encapsulated with a non
conductive epoxy resin.
Applications
The MA45471 is well suited for MRI Passive switching
applications. The PIN diodes become a high Q, R-C
network under small signal and behave as an effective
passive rectifier or short circuit under high RF Signal to
tune and de-tune the resonant MRI tank circuit. The
anti-parallel arrangement provides for more efficient
RF power handling.
