Power Integrations LNK6406D
LNK6406D variants from Power Integrations
LNK6406D Overview
What changes between part numbers, and what to check before you lock the BOM — AC DC Converters and Offline Switchers.
Key Features
- Footprint / package: SO-8C, 8-SOIC (0.154", 3.90mm Width), 7 LeadsLand pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
Target Applications
- AC DC Converters and Offline Switchers — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Ordering Variants
Compare 2 LNK6406D part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| LNK6406D | Package: SO-8C | Mounting Type: Surface Mount | Max Input Voltage: 264 V | Max Operating Temp: 150 °C | Min Operating Temp: -40 °C | SO-8C | Power Integrations | Active | Compliant | In Stock | |
| LNK6406D-TL | Package: 8-SOIC (0.154", 3.90mm Width), 7 Leads | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 150°C (TJ) | Supplier Device Package: SO-8C | Voltage Breakdown: 725V | Power Watts: 6.1 W | 8-SOIC (0.154", 3.90mm Width), 7 Leads | Power Integrations | Active | Compliant | In Stock |

How to Choose the Right LNK6406D AC DC Converters and Offline Switchers
Match the footprint first
Packages here: SO-8C, 8-SOIC (0.154", 3.90mm Width), 7 Leads. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LNK6406D, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "LNK6406D" — include the full suffix (e.g. TL). RFQ with reel/tube preference and required date code.
