Frequently Asked Questions

How much transient energy can the SMBJ24A absorb during a surge event?

The SMBJ24A is rated to dissipate up to 600W of peak pulse power while clamping transients to a maximum of 38.9V, protecting circuits operating near a 24V rail from voltage spikes and electrostatic discharge events.

How many pins does the SMBJ24A's SMB package provide for board mounting?

The SMBJ24A is housed in a 2-pin SMB package, a compact surface-mount footprint that supports the diode's 600W peak pulse rating while minimizing board space in surge-protection circuits.

Why do buyers check lead time and lifecycle ratings before ordering the SMBJ24A?

STMicroelectronics lists a factory lead time of about 19 weeks and a YTEOL rating of 7 years for the SMBJ24A, so procurement teams sourcing this 600W TVS diode for production programs should plan orders accordingly.
