| Dual Anti- Parallel Pair PIN Diode Features MA44781 V2 * * * * * Surface Mount Packages Anti-Parallel Pair Construction SPC Process for Superior C-V Repeatability Designed for MRI applications Lead-Free (RoHs Compliant) equivalents available with 260C reflow compatibility Absolute Maximum Ratings @ TA=+25 C (Unless Otherwise Noted) 1 Parameter Reverse Voltage Forward Current (per each diode) Total Power Dissipation2 Operating Temperature Storage Temperature Absolute Maximum 60V 100 mA3 250 mW -55 C to +125 C -55 C to +125 C Description The MA44781 is a silicon PIN diodes in surface mount packages. There are two sets of two PIN diode pairs constructed in opposing configurations. The package is sealed with a non-conductive epoxy resin and is suitable for surface mount applications. Applications The MA44781 Device is well suited for MRI Passive switching applications. The PIN Diodes become high Q, R-C elements under small signal and behave as effective passive rectifiers or short circuits under high RF Signal to tune and de-tune the resonant MRI tank circuit. The anti-parallel doublet arrangement provides for more efficient RF power handling. 1. Operation of this device above any one of these parameters may cause permanent damage. 2.
