Its 33 V reverse standoff voltage means it stays transparent on a 33 V rail until a transient exceeds the 36.7 V minimum breakdown threshold, then clamps at 59 V maximum while shunting 10.2 A peak pulse current. The single bidirectional channel protects both polarities on a signal or power line, so one device replaces two unidirectional TVS diodes in series-opposing configuration. The DO-214AA (SMB) package is a standard surface-mount footprint with a 0.050-inch pitch and a low-profile body that suits dense PCB layouts. ## Clamping voltage and peak pulse current — the real protection margin The 59 V maximum clamping voltage at 10.2 A peak pulse current defines the voltage the protected circuitry sees during a surge. For a 33 V rail, that 26 V headroom above the standoff is typical for a 600 W TVS in this voltage class. If the downstream components have a 60 V absolute maximum rating, this part keeps the transient under that ceiling — but if the load is a 5 V logic rail, the clamp is too high and a lower-voltage TVS is needed. ## Active production — no last-time buy pressure Microchip lists the SMBJ33CE3/TR13 as Active.","metaTitle":"SMBJ33CE3/TR13 TVS Diode – 600 W, 33 V Bidirectional","metaDescription":"SMBJ33CE3/TR13 from Microchip Technology: 600 W peak pulse power, 33 V reverse standoff, bidirectional Zener TVS in DO-214AA (SMB).
