| Working Peak Reverse Voltage |
The 1SMA51AT3G from ON Semiconductor is a unidirectional transient voltage suppressor (TVS) diode from the 1SMA5.0AT3 series. It is designed to protect voltage-sensitive components from high-voltage, high-energy transients. The device offers a working peak reverse voltage of 51 V and a clamping voltage of 82.4 V.
Key electrical specifications include a peak power dissipation of 400 W at 1 ms pulse width, a typical response time of less than 1 ns, and an ESD rating of Class 3 (>16 kV) per Human Body Model. The diode has a capacitance of 250 pF at 1 MHz and can handle a forward surge current of 40 A.
The device is housed in a void-free, transfer-molded plastic SMA (DO-214AC) package, suitable for surface mount assembly. It supports operating junction temperatures from -65°C to 150°C and has a moisture sensitivity level of 1 (unlimited). This Pb-free variant (suffix G) is RoHS and REACH compliant.
The working peak reverse voltage is 51 V.
The clamping voltage is 82.4 V.
The peak power dissipation is 400 W at a 1 ms pulse width.
The device is available in an SMA (DO-214AC) surface-mount package.
It is a unidirectional TVS diode. Polarity is indicated by a cathode notch or band.
The operating junction temperature range is -65°C to 150°C.
The typical response time is less than 1 ns.
