The SMBJ160CA-13-F: The 160V reverse standoff voltage sets the maximum continuous DC or AC peak voltage the protected line can carry without the diode conducting — stay below this for normal operation. When a transient exceeds the 178V minimum breakdown voltage, the diode clamps the surge to 259V maximum, limiting the voltage the downstream IC sees. The 2.3A peak pulse current rating at the standard 10/1000µs telecom waveform tells you the diode can sink that much surge current before the junction overheats.
DO-214AA SMB — footprint and field swap
Housed in the DO-214AA SMB package, this is a surface-mount part that reflows onto standard 0.100-inch pitch pads. The body is large enough to hand-solder with a fine-tip iron if you are doing a quick field repair — no hot-air station required, but watch the pad orientation: the cathode band on the body marks the side that connects to the line being protected, though for a bidirectional part polarity does not matter for function. Operating junction temperature range spans -55°C to 150°C, so it survives both cold storage and the heat of a reflow profile or a warm enclosure. General-purpose application means it is not qualified to automotive AEC-Q101 — it is intended for industrial, telecom, and consumer boards where the ambient stays below 85°C.
Active production, sourced to order
Product status is Active — Diodes Incorporated continues to manufacture this part. The base product number SMBJ160 covers the whole family; the -13-F suffix indicates the tape-and-reel packaging variant.
