The onsemi 1SMB18CAT3 is a transient voltage suppressor (TVS) diode designed for robust overvoltage protection. This SMB package device features an 18V standoff voltage and a 29.2V maximum clamping voltage at a peak pulse current of 20.5A (10/1000µs). With a 600W peak pulse power dissipation, it offers effective protection against fast transient surges. The bidirectional design provides 1 channel of protection, suitable for general-purpose applications. Key electrical parameters include a 20V minimum breakdown voltage and a typical capacitance of 465pF at 1MHz. The 1SMB18CAT3 operates within a temperature range of -65°C to 150°C (TJ) and is supplied in Tape & Reel packaging. Its performance characteristics make it suitable for applications in industrial and automotive sectors.
