Completed the part review and created Part Verification Report — SZESD5Z5.0T5G. The datasheet URL was already present, and I also found the official onsemi datasheet; key issues flagged are wrong package/mount metadata, an unusable footprint, and an incomplete generic-terminal symbol.
Open items:
- Footprint should be corrected to SOD-523 land pattern before manufacturing.
- Symbol should be converted to a proper diode/TVS symbol with Cathode/Anode pin descriptions.
- I filed an internal part quality issue for the severe footprint/metadata mismatches.
Suggested next steps:
- Ask me to fix the footprint and symbol in this part project.
- Ask me to update package/mount metadata to match the datasheet.
- Ask me to re-run verification after corrections.
Fix and verify
Fix footprint symbol
Update metadata

Symbol / Pin Cross-Check
Table
| Datasheet requirement | Current schematic representation | Result |
|---|---|---|
| Pin 1 = Cathode | Component K, Pin Number 1, Pin Type Passive | Electrically identifiable, but implemented as generic terminal rather than diode symbol terminal |
| Pin 2 = Anode | Component A, Pin Number 2, Pin Type Passive | Electrically identifiable, but implemented as generic terminal rather than diode symbol terminal |
| Symbol should clearly be a diode/TVS diode | Two independent Terminal components named K and A | Mismatch / incomplete symbol quality |
| Pin descriptions should state Cathode and Anode | No explicit Pin Description values; only designators K/A and pin numbers | Mismatch / incomplete metadata |
Footprint Cross-Check
Table
| Datasheet requirement | Current footprint | Result |
|---|---|---|
| SOD-523 / Case 502 | Root footprint has no package sizing rules | Mismatch |
| Two SMT pads | Two pads exist | Partial match |
| Pad geometry about 0.48 mm x 0.40 mm each | Pads K and A are circular, size 0.0016 mm x 0.0016 mm | Severe mismatch |
| Pad spacing / total span about 1.80 mm | Both pads are at x=0, y=0 | Severe mismatch |
| Polarity: Pin 1 cathode at polarity band | No silkscreen/body/polarity marking detected | Mismatch |
Mismatch Summary
- Package metadata mismatch: Flux property says
TO, but datasheet specifies SOD-523, Case 502, Style 1. - Mount metadata mismatch: Flux property says
Clamp, but this is a surface-mount diode package. - Footprint is not usable as-is: both pads are effectively zero-sized circular pads at the same origin; this does not match the SOD-523 land pattern.
- Symbol is incomplete: schematic is represented by two generic terminals rather than a diode/TVS symbol, with no explicit pin descriptions.
- Pin numbering is directionally correct:
K= pin 1 cathode andA= pin 2 anode matches the datasheet, but it should be encoded as proper diode terminals with descriptions.
Recommended Corrections
- Change package metadata to
SOD-523/Case 502. - Change mount metadata to
SMDor equivalent surface-mount value. - Replace or override footprint pads to match the datasheet recommended footprint: two rectangular SMT pads, 0.48 mm x 0.40 mm each, arranged for 1.80 mm overall span.
- Add package outline and polarity/cathode marking consistent with SOD-523 Style 1.
- Convert the schematic symbol from two generic terminals into a diode/TVS diode symbol with explicit pin descriptions:
- Pin 1: Cathode
- Pin 2: Anode
Internal Quality Escalation
The part appears incorrect enough that it should not be used for manufacturing without correction. An internal part quality issue was filed for the footprint and metadata mismatches.
