With a reverse standoff of 20 V and a breakdown minimum of 22.2 V, it sits across a 20 V bus and stays out of the way until a transient pushes past the threshold. The 46.3 A peak current rating (again at 10/1000 µs) tells you the surge it can handle before the die gives up. ## Bidirectional — one part for AC or bipolar lines This is a single bidirectional channel, not two back-to-back unidirectional parts in one package. That matters when you are clamping a signal pair that swings both sides of ground — an RS-485 line, a 20 VAC sensor supply, or a DC bus that can reverse polarity during a fault. One part covers both polarities with the same clamping voltage. ## DO-214AB SMC — fits the reflow profile The DO-214AB (SMC) package is a standard surface-mount footprint with a solderable tab on the bottom for thermal transfer. The -55 to 150 °C junction range covers the full industrial temperature band — no derating headache for a panel that sees 85 °C ambient. ## Active production — no LTB scramble Diodes Incorporated lists the SMCJ20CA-13 as Active. No last-time-buy clock ticking, no successor to chase. For a BOM that needs a 20 V bidirectional TVS in the SMC footprint, this part is a straightforward line item — order it against the RFQ and move on.","metaTitle":"SMCJ20CA-13 Diodes Inc TVS, 1.5kW 20V Bidirectional, SMC","metaDescription":"SMCJ20CA-13 TVS diode, 1500W peak pulse, 20V reverse standoff, 32.4V clamp, bidirectional, DO-214AB SMC.
