and the lowest forward voltage drop for devices in their class, but they also provide the lowest junction capacitance and fastest recovery time. The Vishay Semiconductors rectifiers introduced today include the VS-E7SX0112-M3V, VS-E7SX0212-M3V, and VS-E7SX0312-M3V models, as well as the AEC-Q101-certified VS-E7SX0112HM3V, VS-E7SX0212HM3V, and VS-E7SX0312HM3V models. To reduce switching losses and increase efficiency, the devices combine a fast recovery time of 50 ns with a Qrr as low as 105 nC (typical), a forward voltage drop as low as 1.45 V, and a junction capacitance as low as 7.25 pF
These robust rectifiers offer a non-repetitive surge current peak of up to 70 A in a compact 4.3 mm x 6.5 mm package with a low-profile 1.1 mm footprint, compatible with the TO-277A. Combined with a minimum creepage distance of 5.4 mm and a molding compound with a Comparative Tracking Index (CTI) ≥ 600 (Material Group I), these devices reduce the number of components and bill of materials (BOM) costs in accordance with the requirements of IEC 60664-1 for high-voltage applications.
The VS-E7SX0112-M3V, VS-E7SX0212-M3V, VS-E7SX0312-M3V, VS-E7SX0112HM3V, VS-E7SX0212HM3V, and VS-E7SX0312HM3V models will serve as blocking, snubber, and freewheeling diodes in flyback auxiliary power supplies and high-frequency rectifiers for bootstrap driver functionality, while also providing desaturation protection for the latest high-voltage Si/SiC fast-switching IGBTs and MOSFETs. Typical applications for these devices include industrial drives and tools, integrated chargers and electric vehicle (EV) motors, energy generation and storage systems, as well as Ćuk converters and industrial SEPIC LED circuits.
The rectifiers feature a flat structure and platinum doping for enhanced lifespan, ensuring system reliability and robustness without compromising performance. Their optimized stored charge and low recovery current minimize switching losses and reduce power dissipation. These RoHS-compliant, halogen-free devices have a moisture sensitivity level (MSL) of 1 according to J-STD-020 and can operate at high temperatures up to +175 °C.
