Frequently Asked Questions
How does the SMAJ24CA-13-F clamp transient overvoltages across a 24 V protected line?
Under transient conditions, the SMAJ24CA-13-F conducts when the line exceeds its 26.7 V minimum breakdown voltage and clamps the peak voltage to 38.9 V maximum. The bidirectional configuration handles transients on both polarities, protecting circuits that see 24 V nominal signals. Its DO-214AC SMA package dissipates peak pulse power effectively, ensuring the protected downstream electronics remain within their safe operating area.
For an RS-485 or industrial sensor bus at 24 V, how does the bidirectional design of the SMAJ24CA-13-F aid protection?
RS-485 buses and industrial sensor lines carry differential signals that can swing both positive and negative, requiring bidirectional TVS protection. The SMAJ24CA-13-F handles ±24 V standoff with a 38.9 V clamping voltage on both polarities, absorbing lightning-induced surges and ESD events without requiring two separate unidirectional diodes. A single 2-pin SMA footprint keeps BOM simple while delivering full bidirectional surge protection.
What alternatives should designers evaluate when the 38.9 V clamping voltage of the SMAJ24CA-13-F is too high for a tighter protection window?
When a tighter clamp below 38.9 V is required for circuits with lower absolute maximum ratings, designers may consider lower-standoff SMAJ series variants such as SMAJ15CA or SMAJ18CA, which clamp at 24.4 V and 29.2 V respectively. Alternatively, selecting a transient-voltage suppressor from the P6SMB or SMBJ series with a closer breakdown voltage tolerance can tighten the 2-pin SMA protection window to within ±5% of the target clamping level.
