It clamps at 15.4 V maximum and blocks up to 9 V reverse standoff, so it sits on a 9 V rail — common in 9 V sensor supplies, 9 V battery-powered equipment, or 9 V reference lines in industrial control boards. ## Breakdown and clamping — the numbers that matter for your rail Minimum breakdown voltage is 10 V, so a 9 V rail sees no leakage until the transient pushes past 10 V. The 15.4 V clamp at 39 A peak pulse current means the downstream circuitry must survive that voltage for the pulse duration — check your DC/DC converter or load switch absolute maximum. Bidirectional construction (one channel) suits AC-coupled signal lines or bipolar supplies where the transient can swing either polarity. No power line protection — this part is for signal or low-power rail clamping, not mains. ## Package, lifecycle, and sourcing posture The footprint is shared across the SMBJ family, so a BOM change to a different voltage rating (e.g., SMBJ5.0CA or SMBJ12CA) lands on the same pads. The base product number SMBJ9.0 covers both unidirectional and bidirectional variants; the CA in the order code marks this as bidirectional.","metaTitle":"SMBJ9.0CAE3/TR13 Microchip Zener TVS, 9V Standoff, 600W","metaDescription":"SMBJ9.0CAE3/TR13 Zener TVS diode from Microchip Technology. 9V reverse standoff, 15.4V clamping, 600W peak pulse power.
