Evalu.
Considering.
1) Available part information in the project
2) Datasheet status
| Check | Result |
|---|---|
| Datasheet already set? | Yes |
| Web lookup needed? | No |
| Action needed to add/update datasheet property? | No |
3) Datasheet summary
| Category | Extracted metadata |
|---|---|
| Product family | Low VF SMD Schottky bridge rectifiers |
| Specific device | CDBHM260L-HF |
| Package | MBS-2 |
| Reverse voltage | VRRM = 60 V |
| RMS voltage | Family table includes VRMS values by variant; the 60 V variant corresponds to the device family position for CDBHM260L-HF |
| DC blocking voltage | VDC = 60 V |
| Average forward rectified current | I(AV) = 2.0 A @ TL = 100 °C |
| Peak forward surge current | IFSM = 50 A |
| Forward voltage | VF = 0.70 V at 2.0 A DC |
| Reverse current | IR = 1.0 mA @ TJ = 25 °C, 20 mA @ TJ = 100 °C |
| Junction capacitance | Datasheet extract returned CJ = 125 pF in one result and a family table extract also included 80 pF; this looks like a family-table ambiguity and should be read directly from the original PDF before publishing final parametrics |
| Thermal resistance | Datasheet extract returned RθJA = 20 °C/W; another family-table extract included multiple values, so use 20 °C/W unless manually verified otherwise from the PDF |
| Operating temperature | -55 to +125 °C |
| Storage temperature | -55 to +150 °C |
| Mechanical notes | Molded plastic case, polarity indicated on package, approx. 0.125 g, reel 3000 pcs, reel size 13 in |
| Features | Surface mount, metal-semiconductor junction with guarding, very low forward voltage drop, epitaxial construction, Pb-free, halogen-free, UL 94V-0 plastic, high current capability |
4) Absolute maximum / operating data
| Parameter | Value |
|---|---|
| VRRM | 60 V |
| VDC | 60 V |
| I(AV) | 2.0 A |
| IFSM | 50 A |
| VF | 0.70 V @ 2.0 A |
| IR | 1.0 mA @ 25 °C, 20 mA @ 100 °C |
| TJ | -55 to +125 °C |
| TSTG | -55 to +150 °C |
5) Pin / terminal information
| Project terminal | Project pin number | Intended function from symbol | Datasheet evidence |
|---|---|---|---|
| ~_1 | 1 | AC input | Datasheet confirms standard bridge-rectifier arrangement in MBS-2 package |
| ~_2 | 2 | AC input | Datasheet confirms standard bridge-rectifier arrangement in MBS-2 package |
| 3 | Positive DC output | Datasheet polarity mark includes + | |
| - | 4 | Negative DC output | Datasheet polarity mark includes - |
- Overall body dimensions include 7.0 mm max and widths around 4.2 mm, 4.5 mm, 4.9 mm
- Lead / terminal related dimensions include 0.15 mm, 0.35 mm, 0.50 mm, 0.80 mm
- Additional outline values include 0.7 mm, 0.9 mm, 1.1 mm, 1.3 mm, 1.7 mm, 2.3 mm, 2.7 mm
- Chamfer callout: 0.5 mm x 45°
7) Cross-check of symbol and footprint vs datasheet
| Check | Result | Risk |
|---|---|---|
| Pin count | Pass: project has 4 terminals and footprint has 4 pads | Low |
| Package family | Pass: project description says MBS-2, datasheet says MBS-2 | Low |
| Polarity presence | Pass: project symbol exposes + and -, datasheet marks polarity on package | Low |
| AC terminals present | Pass: project symbol exposes two AC terminals, ~_1 and ~_2 | Low |
| Explicit pin descriptions | Weak: project pins are generic terminals with undefined pin names beyond symbol labels | Medium |
| Pin-type metadata | Weak: all four project terminals are marked Pin Type: Unspecified | Medium |
| Footprint pad geometry | Not fully verifiable from available layout metadata; only pad existence was exposed, not exact pad sizes / spacing | Medium |
| Pin-number-to-physical-pad mapping | Not fully proven from tool-visible geometry; project uses mapping 1= | Medium |
8) Mismatches / issues to flag
| Issue | Why it matters | Severity |
|---|---|---|
| Generic symbol metadata instead of explicit bridge-rectifier pin descriptions | Can cause ambiguity during reuse, export, or later library QA | Medium |
| Pin types left as Unspecified | Reduces ERC quality and can hide mistakes in downstream designs using this part | Medium |
| Footprint dimensions not fully validated against labeled datasheet drawing | A wrong MBS-2 land pattern could cause assembly failure or solderability issues | High if unverified |
| Datasheet extraction ambiguity on some family-table values like CJ and RθJA | Could lead to incorrect structured properties if copied blindly into the part metadata | Medium |
- The part project is mostly consistent with the datasheet at a high level: 4 pins, bridge rectifier, MBS-2, polarity outputs present.
- I do not see an obvious symbol-level polarity reversal.
- The main remaining manufacturing risk is that the footprint geometry and exact pad mapping are not fully validated from the metadata currently exposed.
- The main library-quality issues are:
