The DFN3820A series of surface-mount standard rectifiers from Vishay are available in a 3.85 mm x 2.08 mm x 0.88 mm leadless DFN package that is ideal for space-constrained designs. The rectifiers may be used in circuits performing functions including power line polarity protection and rail-to-rail protection.
The inclusion of side-wettable flanks supports automated optical inspection and placement for streamlined manufacturing. The DFN3820A package is also footprint-compatible with designs using rectifiers with a DO-220AA package. This makes the SExxNx series of standard rectifiers suitable for upgrading existing board layouts with more eco-friendly technology.
The SExxNx surface-mount rectifiers feature an oxide planar chip single-junction architecture with low forward-voltage drop. The family includes models supporting a maximum repetitive peak reverse voltage of 200 V, 400 V, or 600 V.
The full operating junction-temperature range of the SE20 rectifiers is -55°C to 175°C, and the reverse current measured at a junction temperature of 125°C is less than 100 μA. The SE20 surface-mount rectifiers can withstand a peak forward current of 32 A for up to 10 ms of half sine-wave surge activity.
