Product Detail

Zero Bias Detector Diode
The MZB604 ZBD diode is a sensitive, very low barrier height Schottky diode designed for use in high frequency, low input power detectors. It is known as a zero bias detector (ZBD) since its very low barrier height results in excellent sensitivity to very small signals without the need for external bias current. This diode is available as a five-junction common-anode chip, as a single-junction beam lead or packaged in one of several suitable packages. It is manufactured using MACOM proven diode fabrication process which optimizes diode characteristics for optimal electrical performance and excellent reliability. The low junction capacitance (0.2 pF typical) of the MZB604 enables the device to be used in sensitive detector circuits with input signals up to 20 GHz. This rugged device is capable of reliable operation in all military, commercial and industrial applications. The device is RoHS compliant.
