The 22.2V minimum breakdown voltage and 32.4V clamping voltage define the protection window: the rail must tolerate the clamp level during a surge, and the breakdown must sit above the steady-state 20V supply. Housed in the DO-214AA (SMB) package, this TVS is a drop-in fit for standard SMD reflow processes. The -65°C to 150°C junction temperature range covers cold-crank and underhood environments, though derating the peak pulse power above 25°C is necessary per the datasheet curve. ## Active production – sourcing posture Microchip lists the SMBJ20CAE3/TR13 as Active. Because it is a current-production part, there is no last-time-buy pressure.","metaTitle":"SMBJ20CAE3/TR13 – Microchip Zener TVS, 20V, 600W, DO-214AA","metaDescription":"SMBJ20CAE3/TR13 – Microchip Zener TVS diode, 20V reverse standoff, 600W peak pulse, DO-214AA SMD.
