That 58.1 V ceiling is the number that protects downstream semiconductors: the protected rail sees no more than that voltage regardless of the surge magnitude, up to the rated peak. ## 36 V standoff with 40 V minimum breakdown — the design headroom The reverse standoff voltage of 36 V is the working rail the TVS sees in normal operation — it sits idle above this level without conducting. The 40 V minimum breakdown sits above the standoff with margin: the part does not clip until a transient pushes the rail above 40 V, which means there is 4 V of design headroom between the nominal rail and the onset of protection. For a 36 V system bus, that margin is standard practice. ## DO-214AB SMC — standard footprint, no rework surprises The DO-214AB (SMC) package follows the industry-standard JEDEC DO-214AB land pattern — any SMC footprint on the board accepts this part without pad modification. The cathodeside metallisation and the central heatsink slug under the body conduct the transient thermal load to the PCB copper during a clamping event. Solder-joint profile is standard lead-free: a paste-in-plate reflow with a 260 °C peak satisfies the Diotec assembly guidance for this package. ## Unidirectional Zener — polarity and where it fits One unidirectional channel means the part clamps only one polarity — positive transients on the line relative to ground. It does not handle negative spikes or bipolar swing. For a 36 V DC rail protection, that covers the primary fault direction; AC-coupled lines or rails that see bidirectional swing need the bidirectional variant of this series.","metaTitle":"1.5SMCJ36A TVS Diode, 36V Standoff, 1.5 kW","metaDescription":"Diotec 1.5SMCJ36A unidirectional Zener TVS, 36 V standoff, 58.1 V clamping, 1.5 kW peak pulse.
