Package
Low operating Voltage
The UM9441 is an axially leaded device
region. These charges are swept out by constructed by metallurgically bonding the

refractory pins that are typically 0.125
inches in diameter and 0.050 inches long.
Hyper-pure glass is then fused over this
bond to form a void less seal. Leads are then
brazed to ends of molybdenum pins. This
results in a high-reliability package using
The Microsemi UM9441 series
utilizes high resistivity material and is
designed to have a uniform area mesa
structure to define the active volume.
APPLICATIONS/BENEFITS
