1N5932BRLG is an avalanche diode that is part of ON Semiconductor's switching family of Avalanche Diodes. It is a dual diode that has a reverse breakdown voltage of 30V, a forward voltage of 0.7V, an operating temperature range of -65°C to 125°C and a maximum operating temperature of 150°C. It is used to protect against voltages that go above or below a certain point. It also has a low capacitance, making it ideal for high frequency protection applications.
