Tunnel Diodes: MBD Series

The Aeroflex / Metelics MBD series of Planar Back (Tunnel) Diodes are fabricated on germanium substrates with passivated, planar construction and all gold metallization for reliable operation up to +110 ºC. Unlike the standard tunnel diode IP is minimized for detector operation and binned in five values offering varying degrees of sensitivity and video impedance. The back detector is
generally operated with zero bias and is known for its excellent temperature stability and fast video rise times.
