The 1SMB28AT3 is a 600W peak power unidirectional transient voltage suppressor (TVS) diode from ON Semiconductor. It is designed to protect voltage-sensitive components from high-voltage, high-energy transients. The device features a working peak reverse voltage of 28V and a maximum clamping voltage of 45.4V at 13.2A peak pulse current. It has a typical response time of less than 1 nanosecond and an ESD rating exceeding 16 kV per the Human Body Model.
With a peak power dissipation of 600W at 1ms pulse width and a DC power dissipation of 3.0W at lead temperature 75°C, this diode is suitable for a variety of circuit protection applications. The junction capacitance is 590 pF at 1 MHz, and the operating temperature range is -65°C to 150°C. The device is unidirectional with cathode polarity indicated by a band.
The 1SMB28AT3 is supplied in a void-free, transfer-molded plastic surface-mount package (DO-214AA, SMB). The leads have a modified L-bend design for improved contact area and are readily solderable. The maximum case temperature for soldering is 260°C for 10 seconds. This component is RoHS compliant (claimed) with MSL level 1 and REACH unaffected (unverified).
