The Vishay Dale SMF28A-E3-08 is a TVS (Transient Voltage Suppressor) diode in a compact DO-219AB (SMF) package, suitable for surface-mount applications. It provides robust protection against transient voltage events, featuring a 200W peak pulse power capability with a 10/1000 μs waveform and ±30 kV ESD immunity according to IEC 61000-4-2.
This general-purpose diode has a nominal breakdown voltage of 28V and a maximum clamping voltage of 45.4V at 4.4A. Its low profile and wave/reflow solderability make it easy to integrate into various electronic designs. The operating temperature range is -65°C to 175°C, ensuring reliability in demanding environments. The SMF28A-E3-08 is also AEC-Q101 qualified, indicating its suitability for automotive applications.
Key electrical characteristics include a capacitance of 227pF at 1MHz and a peak forward surge current rating of 50A for an 8.3 ms single half sine-wave. The thermal resistance is 180 K/W when mounted on a standard PCB. The flammability rating is UL 94 V-0, and it is rated MSL level 1 for moisture sensitivity.
