TO-220 FullPAK Narrow Lead
Package solution for height reduction in adapter and charger applications
TO-220 FullPAK Narrow Lead package is developed to fully address the customer needs with regard to height reduction requirements in adapter and charger applications.
For charger and adapter applications with power over 20W, TO-220 FullPAK is the preferred package because of its ease of handling and superior thermal performance. However, the need for height reduction in slim and semi-slim adapters forces manufactures to fully insert TO-220 FullPAK into PCB rather than up to its standoff. This often causes yield and reliability challenges due to:
- Significantly increased hole size on PCB to accommodate wider standoff as compared to leg
- Deceased effective creepage distance (shortest hole-to-hole distance)
- Increased possibility to have solder short on PCB
