Description
The MA44781 is a silicon PIN diodes in surface
mount packages. There are two sets of two PIN di-
ode pairs constructed in opposing configurations.
The package is sealed with a non-conductive epoxy
resin and is suitable for surface mount applications.
-55 °C to +125 °C
-55 °C to +125 °C
1. Operation of this device above any one of these parameters
may cause permanent damage.
2. Please refer to application note M538 for surface mounting
instructions
3. Total current per diode= I (rms) + I (dc) @ +25C
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.
