The bidirectional configuration means a single device protects both polarities, simplifying layout on AC or bipolar DC lines. When a transient exceeds the minimum breakdown voltage of 44.4V, the device starts clamping, holding the peak at 64.5V maximum. That 64.5V clamp is the voltage the downstream components must survive; if your 40V-rated capacitors or ICs see more than that during a surge, this diode provides the protection margin. The 9.3A peak pulse current rating (at 10/1000µs) defines the surge the diode can absorb without damage. For a given transient energy, a lower clamp voltage means less stress on the protected circuit, but the diode itself must handle the current. ## Active production — sourcing and lifecycle posture The DO-214AA SMB footprint is industry-standard, so the reel feeds directly into existing lines without feeder changeovers. ## General-purpose application fit Listed for general-purpose applications, this diode suits power-supply input protection, DC bus clamping, signal-line transient suppression, and secondary-side rectifier snubbing. The wide temperature range and bidirectional capability make it a versatile choice for industrial, automotive, and telecom boards where a single device must handle both positive and negative surges.","metaTitle":"SMBJ40CAE3/TR13 TVS Diode – 40V Bidirectional, 600W","metaDescription":"Microchip Technology SMBJ40CAE3/TR13 Zener TVS diode, 40V reverse standoff, 64.5V clamp, 600W peak pulse, DO-214AA SMB.
