The Vishay Dale SMF33A-HE3-18 is a surface-mount Transient Voltage Suppressor (TVS) diode designed for robust protection against voltage transients. It offers a 33V standoff voltage and a clamping voltage of 53.3V at 3.8A.
With a peak pulse power rating of 200W for a 10/1000 μs waveform and 1000W for an 8/20 μs waveform, this diode provides significant protection for sensitive electronic components. It also features ESD immunity up to ±30 kV contact and air discharge, aligning with IEC 61000-4-2 standards.
The device is housed in a compact DO-219AB (SMF) package, suitable for surface mounting. Its operating temperature range is -65°C to 175°C, making it suitable for demanding environments. The SMF33A-HE3-18 is also qualified for automotive applications and meets UL 94 V-0 flammability rating.
