Products within the single rectifier diode family are used to allow current flow in one direction only, and implement exactly one instance of this function per device package. Diodes used for other purposes (including zener and variable capacitance diodes) are listed separately in product families of their own, as are products incorporating multiple diodes per device package.
Technology: Indicates which among several common diode construction methods a device employs. Has categorical influence on operating characteristics such as leakage current, recovery time, forward voltage, etc.
Voltage - DC Reverse (Vr) (Max): The maximum voltage that a device is rated to withstand in a reverse-biased or “blocking” mode. Exceeding this voltage may damage the device or other system components.
Current - Average Rectified (Io): Indicates the maximum, time-averaged current-carrying capacity of a device as indicated by the manufacturer. Allowable values in practice are affected by thermal considerations.
Voltage - Forward (Vf) (Max) @ If: Characterizes the voltage drop across a forward-biased diode, measured at the test current indicated.
Speed: Indicates the recovery time or lack thereof.
Reverse Recovery Time (trr): The amount of time required for a diode to transition from a forward-conducting to a reverse-blocking state, during which time current may flow through the device in the reverse direction. Measured under manufacturer-defined test conditions.
Current - Reverse Leakage @ Vr: Characterizes current flow through a diode-based device resulting from application of a reverse-bias voltage of the indicated magnitude, under manufacturer-defined test conditions. Observed values vary with temperature.
Capacitance @ Vr, F: Characterizes the capacitance exhibited by a device when reverse-biased, at the indicated values of reverse voltage and test frequency.
Mounting Type: Indicates how the device is attached.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the suppliers device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than to go by this terminology when designing your circuit.
Operating Temperature - Junction: Indicates a device’s maximum rated operating temperature range, as measured at the electrically active portion of the device.
