Decreasing Switching Losses and Rising Effectivity, Gadgets Mix Low Qrr All the way down to 105 nC With VF All the way down to 1.45 V and Low Junction Capacitance and Restoration Time
Vishay Intertechnology, Inc. expanded its Gen 7 platform of 1200 V FRED Pt Hyperfast rectifiers with 4 new units within the eSMP collection SlimSMA HV (DO-221AC) package deal. Optimized for industrial and automotive purposes, the 1 A and a pair of A rectifiers not solely supply the very best trade-off between reverse restoration cost (Qrr) and ahead voltage drop for units of their class, but additionally present the bottom junction capacitance and restoration time.
The Vishay Semiconductors rectifiers launched, embody the VS-E7JX0112-M3 and VS-E7JX0212-M3, and AEC-Q101 certified VS-E7JX0112HM3 and VS-E7JX0212HM3. To cut back switching losses and improve effectivity, the units mix quick restoration instances right down to 45 ns with Qrr right down to 105 nC typical, ahead voltage drop right down to 1.45 V, and junction capacitance right down to 2.5 pF. The strong rectifiers supply non-repetitive peak surge present as much as 21 A in a compact package deal measuring 2.6 mm by 5.2 mm with a low 0.95 mm profile, in comparison with 2.3 mm for the competing SMA package deal with an identical footprint. Mixed with a minimal 3.2 mm creepage distance and molding compound with a comparative monitoring index (CTI) ≥ 600 (Materials Group I), the units cut back part counts and decrease BOM prices primarily based on IEC 60664-1 necessities for top voltage purposes.
The VS-E7JX0112-M3, VS-E7JX0112HM3, VS-E7JX0212-M3, and VS-E7JX0212HM3 will function clamp, snubber, and freewheeling diodes in flyback auxiliary energy provides and excessive frequency rectifiers for bootstrap driver performance, whereas offering desaturation safety for the newest quick switching IGBTs and excessive voltage Si / SiC MOSFETs. Typical purposes for the units embody industrial drives and instruments, on-board chargers and motors for electrical autos (EV), vitality technology and storage methods, and Ćuk converters and industrial LED SEPIC circuitry.
The rectifiers function a planar construction and platinum doped lifetime management that assure system reliability and robustness with out compromising on efficiency, whereas their optimized saved cost and low restoration present reduce switching losses and cut back energy dissipation. RoHS-compliant and halogen-free, the units function a Moisture Sensitivity Stage of 1 in accordance with J-STD-020 and supply excessive temperature operation to +175 °C.
