1N5820, 1N5821, 1N5822 1N5820 and 1N5822 are Preferred Devices Axial Lead Rectifiers This series employs the Schottky Barrier principle in a large area metal-to-silicon power diode. State-of-the-art geometry features chrome barrier metal, epitaxial construction with oxide passivation and metal overlap contact. Ideally suited for use as rectifiers in low-voltage, high-frequency inverters, free wheeling diodes, and 1N5820, 1N5821, 1N5822 MAXIMUM RATINGS Rating Symbol 1N5820 1N5821 1N5822 Unit Peak Repetitive Reverse Voltage V 20 30 40 V RRM Working Peak Reverse Voltage V RWM DC Blocking Voltage V R Non-Repetitive Peak Reverse Voltage V 24 36 48 V RSM RMS Reverse Voltage V 14 21 28 V R(RMS) Average Rectified Forward Current (Note 1) I A 3.0 O V 0.2 V , T = 95C R(equiv) R(dc) L (R = 28C/W, P.C.
