For a 43 V bus — common in telecom and industrial 48 V systems after a DC-DC converter — the clamping voltage of 69.4 V leaves margin below the typical 80 V abs-max of downstream switching regulators. The 5.7 A peak current is the current the diode shunts; the upstream fuse or PTC must open before the diode's thermal limit is reached under sustained overload. ## Package and board-fit — DO-214AC SMA Housed in the DO-214AC (SMA) package with the supplier device package designation SMA, this diode is a surface-mount device suited for standard reflow soldering. The SMA footprint is a common industry standard; the same pad layout accepts TVS diodes from multiple manufacturers, simplifying second-sourcing. The operating junction temperature range spans -55°C to 150°C. The wide range also means the diode's leakage current at high temperature — a concern for battery-powered equipment — is bounded by the datasheet's high-temperature reverse leakage spec, though that figure is not listed here. ## Active production — no end-of-life urgency Diodes Incorporated lists the SMAJ43A-13-F as Active.","metaTitle":"SMAJ43A-13-F TVS Diode, 400W, 43V, DO-214AC, Diodes Inc","metaDescription":"SMAJ43A-13-F Zener TVS diode, 400W peak pulse power, 43V reverse standoff, DO-214AC SMA.
