Vishay Intertechnology, Inc. today introduced six new rectifiers in the compact, low-profile, surface-mount SMF (DO-219AB) eSMP® package. Offering forward currents of 1A and 2A 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 today 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 40V and 60V reverse voltages and low forward voltage drops down to 0.37V at 1A, 125 degrees 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).
Most rectifiers released today in the SMF package feature a maximum operation junction temperature up to +175 degrees C and an MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of +260 degrees C. Suited 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. Samples and production quantities of the new rectifiers are available now, with lead times of 10 weeks. Pricing for U.S. delivery only starts at $0.10 per piece in quantities below 10,000.
