The 86.1A peak pulse current rating tells you it survives the first-hit surge without going into thermal runaway — critical in automotive ECU input protection where the clamping voltage, not the standoff voltage, determines whether the downstream MOSFET gate oxide survives. ## 36V standoff and the 12V automotive rail The 36V typ reverse standoff voltage sits comfortably above the 14V charging voltage on a 12V automotive rail — the diode sees less than its breakdown during normal operation. Budget your clamp-to-IC-absolute-maximum gap accordingly: a 5.5V safety margin (58.1V clamping vs 52.4V abs-max on a typical 5V rail) is tight but workable with series resistance in the signal path. ## AEC-Q101 qualification and temperature grade If your board runs the diode at full pulse duty, derate the 150°C Tj limit using the thermal impedance curve in the Bourns datasheet to confirm you stay within the 5kW peak rating on your actual pulse width and duty cycle. ## SMC footprint and assembly notes Tape-and-reel packaging suits high-volume pick-and-place lines; cut-tape is available for low-NRE prototyping runs.","metaTitle":"Bourns 5.0SMDJ36CA-Q TVS Diode, 36V 5kW AEC-Q101","metaDescription":"Bourns 5.0SMDJ36CA-Q unidirectional TVS diode, 36V standoff, 58.1V clamping, 5kW peak pulse.

A bidirectional TVS (DA suffix) clamps both polarities, which is needed on differential signal lines or AC-coupled nodes. On a single-ended 12V power rail, unidirectional is the correct choice."},{"question":"Where can I source 5.0SMDJ36CA-Q and get a quote?","answer":"Quoted to order against BOM quantity through independent distribution channels.
