The 1N5388BRLG is a 5 Watt Zener voltage regulator from the 1N53 series, designed for voltage regulation applications. It features a nominal Zener voltage of 200 V at a test current of 5 mA and has a maximum power dissipation of 5 W. The device exhibits a maximum Zener impedance of 480 Ω at the test current and a maximum DC Zener current of 23.6 mA. Housed in a void-free, transfer-molded plastic axial lead package, it offers an operating temperature range of -65°C to +200°C. These characteristics make it suitable for use in voltage regulation, surge suppression, and other protection circuits where a stable high-voltage reference is required.
