IC Role / Device Role / Timing Role: Unidirectional line-to-ground clamp on LIN bus line (12 V nominal), referenced to chassis ground. Use Value: 9.0 V standoff allows full operation across LIN's 8–18 V supply range while clamping transients below 15.4 V to protect LIN transceivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A | Higher clamping voltage (17.5 V @ 12.3 A); SMA package (larger footprint, 4.5 mm × 2.7 mm). | Less suitable for space-constrained USB or CAN FD layouts; better for lower-speed industrial I/O where capacitance <500 pF is not required. | Select SMAJ9.0A only if board area permits larger package and higher clamping is acceptable for downstream IC voltage margins. |
| TPD2E001DRYR | Two-channel, bidirectional, 12 pF typical capacitance; integrated ESD array in 1.6 mm × 1.6 mm DRY package. | Designed for ultra-high-speed interfaces (USB 3.0, HDMI); not AEC-Q101 qualified; lower surge rating (3 A IPPM). | Choose TPD2E001DRYR for compact dual-line protection in non-automotive high-speed designs; avoid where AEC-Q101 or >10 A surge capability is mandatory. |
Compared with SMAJ9.0A and TPD2E001DRYR, SMF9V0A-HE3_A08 uniquely balances AEC-Q101 qualification, 640 pF capacitance, 13.5 A surge handling, and DO-219AB miniaturization - making it optimal for automotive USB/CAN FD nodes requiring proven reliability and layout efficiency.
