Bourns SMBJ28A is a semiconductor diode designed specifically for transient voltage suppression, providing 28 volts of reverse standoff voltage with a peak pulse power dissipation of 600 watts in the DO-214AA package. As a Transient Voltage Suppressor (TVS) diode, it effectively protects sensitive electronic components from overvoltage transients such as those induced by lightning strikes and other voltage spikes by utilising its pn junction characteristics to block or clamp excessive voltages. This diode's low clamping voltage and fast response time make it ideal for safeguarding circuit interfaces in a variety of applications, including telecommunications equipment, automotive electronics, and industrial control systems. With its compact form factor and robust design, the SMBJ28A aids in ensuring the reliability and longevity of electronic systems subject to high voltage transients. https://elecena.pl/product/29542010/bourns-smbj28a-tvs-diode-31-1v-600w-do-214aa-surge-suppression-diode 2025-11-26 https://elecena.pl/product/29542010/bourns-smbj28a-tvs-diode-31-1v-600w-do-214aa-surge-suppression-diode 2026-07-16
