With a peak pulse power rating of 600W and a clamping voltage of 35.8V at 16.7A peak pulse current, this part can handle moderate-energy surges typical of industrial or automotive environments. The single bidirectional channel protects both polarities from a single device — useful for AC-coupled or bipolar signal lines. ## Temperature range and mounting for harsh environments ## Active production — ordering and lifecycle posture Microchip lists the SMBJ20CE3/TR13 as Active, meaning no end-of-life notice is in effect and production continues.","metaTitle":"SMBJ20CE3/TR13 – Microchip 600W Bidirectional TVS Diode","metaDescription":"SMBJ20CE3/TR13 from Microchip Technology: Zener TVS, 20V reverse standoff, 600W peak pulse, bidirectional, DO-214AA (SMB).
