Vishay Intertechnology has introduced six new rectifiers in the compact, low-profile, surface-mount SMF (DO-219AB) eSMP package. Offering forward currents of 1 A and 2 A and low forward voltage drops and leakage currents, the AEC-Q101-qualified devices reduce power losses and improve efficiency in automotive applications.
The devices launched include one standard, three Schottky barrier, and two Hyperfast FRED Pt rectifiers for high-frequency DC/DC converter, freewheeling diode, and power line polarity protection applications in automotive systems, including engine control units (ECU), antilock braking systems (ABS), and LED lighting.
With a compact footprint and low profile, the devices’ SMF package saves significant board space compared with standard SMA, SMB, and SMC packages while increasing power density to reduce overall costs.
The SS1F4HM3, SS1FH6HM3, and SS2FH6HM3 Schottky rectifiers offer 40 V and 60 V reverse voltages and low forward voltage drops down to 0.37 V at 1 A, 125 °C. In addition, the SE10FJHM3 standard rectifier is built on an oxide planar chip technology that provides for class H3B ESD protection (> 8 kV) based on the AEC-Q101-001 human body model (contact mode).
The Hyperfast VS-1EFH02HM3 and VS-2EFH02HM3 FRED Pt rectifiers feature extremely fast and soft recovery characteristics, with recovery times down to 28 ns. The devices offer breakdown voltages of 200 V and low forward voltage drops down to 0.93 V at 1.0 A The rectifiers feature a planar structure and platinum doped lifetime control to guarantee high overall performance, ruggedness, and reliability characteristics.
Most rectifiers released today in the SMF package feature a maximum operation junction temperature up to +175 °C and an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of +260 °C. Ideal for automated placement, the devices are compliant to RoHS Directive 2011/65/EU and halogen-free according to JEDEC JS709A standards, and they meet the JESD 201 class 2 whisker test.
