Zero Bias Operation Low Video Impedance Excellent Temperature Stability Screening per MIL-PRF-19500 and MIL-PRF- 35834 available RoHS* Compliant
Description
The MBD 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 excellent temperature stability and fast video rise times Part Number Junction Capacitance (CJ) Peak Current (IP) Sensitivity (γ) Video Resistance (RV) Reverse Voltage ( VR) Forward Voltage (VF) VR = VV,
