Planar Back (Tunnel) Diodes
MBD Series
Description
The MDB series of back (tunnel) diodes are fabricated
on germanium substrates using passivated, planar
construction and gold metallization for reliable operation up
to +110 °C. Unlike the standard tunnel diode IP is minimized
for detector operation and offered in five nominal values
with varying degrees of sensitivity and video impedance.
The back detector is generally operated with zero bias and
is known for its exellent temperature stability and fast video
rise times.
Features
• Zero bias operation
• Exellent temperature stability
• Low Video Impedance
• Screening per MIL-PRF-19500
and MIL-PRF-35834 available.
