Adding CAN Network with MCP2515
Thought for 51 sec
Automotive TVS options ahead of the regulator
Recommendation
Placement
Table
| Part | Package | Manufacturer | Why it stands out |
|---|---|---|---|
| SMCJ24A-Q | SMC | Bourns | Best balanced choice for the 12 V input ahead of IC1 |
| SM8S24A-Q | DO-218 | Bourns | Heavier-duty option if you want more surge margin at the 39514-5004 entry |
| SMBJ28A-Q | SMB | Bourns | Smaller package option if space matters more than surge robustness |
| SMBJ26A-Q | SMB | Bourns | Similar compact automotive option |
| SMCJ24AQ-13-F | SMC | Diodes | Reasonable alternative to the Bourns SMC part |
- Put the TVS directly behind the 39514-5004, from +12 V to GND, before the input path feeding IC1.
If you want, I can next find a matching reverse-polarity protection part for the same input path.
