Vishay Intertechnology has launched three new series of standard automotive-grade surface-mount rectifiers that are the industry's first devices in the low-profile DFN3820A package with wettable flanks.
Providing high-efficiency, space-saving solutions for power line polarity protection and rail-to-rail protection in commercial, industrial and automotive applications, the 2A SE20Nx, 3A SE30Nx and 4A SE40Nx are available with reverse voltages of 200, 400 and 600 V.
The first package in Vishay's new Power DFN family, the DFN3820A features a compact 3.8 x 2.0 mm footprint and an extremely low 0.88 mm typical height – enabling Vishay General Semiconductor rectifiers to make more efficient use of PCB space.
At the same time, the devices' optimized copper mass design and advanced die placement technology enable superior thermal performance that enables operation at higher current ratings.
Compared to devices in the SMP package (DO-220AA) of the same size, the AEC-Q101 qualified SE20Nx, SE30Nx, and SE40Nx offer a 12% smaller profile and twice the current rating. Additionally, the rectifiers offer equivalent or greater current ratings for larger devices in conventional SMB (DO-214AA) and SMC (DO-214AB) packages, and in the eSMP series SlimSMA (DO-221AC), SlimSMAW (DO-221AD), SMPA (DO-2212BC) and SMPC (TO-2778A).
Featuring a planar oxide chip junction design, the rectifiers offer typical reverse leakage current of less than 0.1 μA, while their low forward voltage drop to 0.86 V reduces power losses to improve efficiency. The devices operate over a wide temperature range of -55° to +175° C and provide ESD capability in compliance with IEC 61000-4-2, air discharge mode.
Ideal for automated positioning, the rectifiers offer an MSL humidity sensitivity level of 1 per J-STD-020, maximum peak LF of 260°C. The devices are RoHS compliant and halogen-free.
