MA45471 MACOM

MA45471 Dual Anti-Parallel Non-Magnetic PIN Diode V1 RoHS Compliant Features Absolute Maximum Ratings @ T =+25 C A 1 Designed for MRI applications (Unless Otherwise Noted) Anti-Parallel Self Bias Arrangement Parameter Absolute Maximum Non-Magnetic Surface Mount Package SPC Process for Superior Parametric Repeatability Reverse Voltage 75V RoHS Compliant with 260C reflow compatibility Forward Current 2A Power Dissipation (per diode) 1.7 W Description The MA45471 device acts as a passive switch using Operating Temperature -55 C to +125 C silicon PIN diodes in a surface mount non magnetic package. The PIN diode pair are arranged in an Storage Temperature -55 C to +125 C anti-parallel configuration and encapsulated with a non Junction Temperature +175 C conductive epoxy resin. 1. Operation of this device above any one of these parameters Applications may cause permanent damage. 2. Please refer to application note M538 for surface mounting The MA45471 is well suited for MRI Passive switching instructions applications. The PIN diodes become a high Q, R-C 3. Total current per diode= I (rms) + I (dc) @ +25C 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.
