The clamping voltage peaks at 243V at the rated peak pulse current of 2.5A under the 10/1000µs waveform. This is a single-channel bidirectional device, so it protects AC signal pairs or bipolar DC rails without needing two diodes back-to-back. ## Peak Pulse Power and Clamp Performance The 2.5A peak pulse current at the clamping voltage of 243V gives the circuit designer a clear window for fuse coordination and downstream device withstand. The bidirectional nature means the clamping characteristic is symmetrical — positive and negative transients are clamped to the same absolute voltage level. This simplifies layout for AC-coupled or bipolar circuits where polarity is not fixed. The DO-214AA (SMB) package has a body width of about 3.6 mm and a height of 2.4 mm, with J-bend leads that self-center during reflow. The cathode band is the only polarity mark — but since this is a bidirectional device, orientation does not matter; the band is present for manufacturing consistency. The pad footprint should follow the SMB land pattern recommended in the datasheet; the thermal pad area under the device is the cathode tab, which also carries the heat to the board copper. Rework with hot air is straightforward: preheat the board to 100-120°C, then direct 300-350°C air at the body for 5-8 seconds until the solder wets. The junction can handle 150°C continuous, so brief rework temperatures are well within the safe operating area. No moisture sensitivity level is listed, but standard MSL 1 handling applies for most SMB TVS diodes — bake at 125°C for 24 hours if the reel has been exposed to high humidity.","metaTitle":"SMBJ150CAE3/TR13 TVS Diode – 150V Standoff, 600W","metaDescription":"Microchip Technology SMBJ150CAE3/TR13 Zener TVS, bidirectional, 150V reverse standoff, 243V clamp, 600W peak pulse, DO-214AA SMB.
