RF Diodes

This Product Selection Guide contains information to help select products in the RF Diodes category on DigiKey.com

RF Diodes are a semiconductor device with two terminals that allows the flow of electricity in one direction and restricts the flow in the other. The devices in this family are used in radio frequency matching circuits for electronic tuning. The diode types are pin, Schottky, and standard, with reverse voltages ranging from 1 to 15,000 volts and current values ranging from 10 mA to 20 A.


Diode Type: 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 - Peak Reverse (Max): The maximum voltage that should be allowed to appear across a device during normal operation. Exceeding this voltage may damage the device or other system components.

Current - Max: Typically this represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.

Capacitance @ Vr, F: Characterizes the capacitance exhibited by a device when reverse-biased, at the indicated values of reverse voltage and test frequency.

Resistance @ If, F: Characterizes the series resistance of a device, for the forward current and test signal frequency indicated.

Power Dissipation (Max): Characterizes the amount of electrical power dissipation in a device that produces a specified internal device temperature (often the rated maximum) under specified operating conditions.

Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.

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 supplier 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.
