Part Datasheet Review
Worked for 26 sec
I’m reading the part project now and checking whether its existing metadata already includes a datasheet link.
Worked for 1 min 25 sec
I found the official TI ESD2CAN24-Q1 datasheet and attached it to the part metadata; now I’m checking pinout and package details against the current symbol and footprint.

ESD2CAN24DBZRQ1 Part Review
Date: 2026-07-20
Scope
Reviewed available part information for the published Flux part
ESD2CAN24DBZRQ1: MPN, manufacturer, package, pin count, description, properties, schematic symbol terminals, PCB footprint, and pin metadata. The official Texas Instruments datasheet was added to the part metadata because the Datasheet URL was initially blank.Part Metadata Found in Flux

Pin Cross-Check
Datasheet pin table for DBZ / DCK package:
Table
| Pin | Datasheet Name | Datasheet Type | Datasheet Description | Flux Current Metadata | Result |
|---|---|---|---|---|---|
| 1 | IO | I/O | ESD protected IO | Pin Type: Bi-Directional; no pin description | Function/type OK; description missing |
| 2 | IO | I/O | ESD protected IO | Pin Type: Bi-Directional; no pin description | Function/type OK; description missing |

Symbol geometry has three terminal symbols and the schematic symbol pin numbers are present. The current symbol does not expose functional pin names/descriptions on the inspected terminal entries.
Footprint Cross-Check
Flux footprint asset:
SOT95P237X112-3N.kicad_mod.Current footprint pads from the KiCad footprint payload:
Table
| Pad | Position (mm) | Size (mm) | Shape | Datasheet Expected |
|---|---|---|---|---|
| 1 | -1.055, -0.95 | 1.24 x 0.59 | Rect | DBZ land pattern: 1.3 x 0.6 mm, pitch/spacing 0.95 mm / 2.1 mm |
| 2 | -1.055, 0.95 | 1.24 x 0.59 | Rect | DBZ land pattern: 1.3 x 0.6 mm, pitch/spacing 0.95 mm / 2.1 mm |
| 3 | 1.055, 0.00 | 1.24 x 0.59 | Rect | DBZ land pattern: 1.3 x 0.6 mm, pitch/spacing 0.95 mm / 2.1 mm |
Footprint outline from the KiCad payload:
- Fab/body outline: approximately 1.30 mm x 2.92 mm, matching the datasheet body range of 1.2-1.4 mm by 2.8-3.04 mm.
- Pin center spacing appears consistent with the datasheet example board layout: 0.95 mm spacing on the two-pin side and about 2.1 mm across the package.
- Pad size is slightly smaller than the TI example land pattern: 1.24 x 0.59 mm vs 1.3 x 0.6 mm. TI notes that IPC-7351 may have alternate designs; the Flux description explicitly references IPC-7351B, so this is likely an IPC-derived nominal footprint rather than a critical mismatch.

Mismatches / Issues Flagged
- Pin 3 type mismatch: datasheet says pin 3 is
GNDtypeG; Flux currently marks pin 3 asPower In. Recommended correction: set Pin Type toGroundand Pin Description toConnect to ground. - Pin descriptions missing: pins 1 and 2 should describe
ESD protected IO; pin 3 should describeConnect to ground. - Part description is incomplete: current description only lists
C / IPC-7351B / 1.12 mm / Texas Instruments. Recommended description:Automotive 2-channel CAN bus ESD protection diode, +/-24 V VRWM, SOT-23-3 (DBZ), AEC-Q101/Q100-oriented Q1 device family. - Part Type property is blank: recommended part type is
ProtectionorDiodedepending library taxonomy preference. - Footprint pad size differs slightly from TI example: current 1.24 x 0.59 mm pads are slightly smaller than TI's 1.3 x 0.6 mm example. Because TI explicitly allows IPC-7351 alternate designs and this part description cites IPC-7351B, this is flagged as a minor review note, not a blocking footprint error.
Overall Assessment
The selected MPN, manufacturer, pin count, package family, and footprint geometry are broadly consistent with the Texas Instruments datasheet for
ESD2CAN24DBZRQ1. The main actionable metadata issue is the schematic terminal metadata: pin 3 should be Ground rather than Power In, and all three pins need datasheet-derived descriptions.Scope
