For a 20 V nominal rail with 10 % tolerance, this gives a 1.8 V guard band between the max steady-state voltage and the TVS trigger point. ## DO-214AA SMB — reflow-ready for pick-and-place Housed in the DO-214AA (SMB) surface-mount package, the SMBJ20A-13 sits on a standard JEDEC footprint with a 2.29 mm body width and 4.57 mm length. The SMB pad geometry is widely supported by solder-paste stencil apertures and reflow profiles — no exotic oven settings needed. The supplier device package is SMB, matching the case code for tape-and-reel feeding. The 150 °C TJ(max) allows the die to handle repetitive surges in a hot enclosure without derating below the 600 W headline figure. The base product number is SMBJ20, which groups this variant with other breakdown-voltage options in the same SMBJ family.","metaTitle":"SMBJ20A-13 TVS Diode, 600W, 20V, DO-214AA SMB","metaDescription":"Diodes Inc SMBJ20A-13 Zener TVS, 600W peak pulse, 20V standoff, 32.4V clamp, unidirectional, DO-214AA SMB.
