Why Choose SMAF 50 Mil Over Standard SS34?
The 50 Mil chip size in SMAF packaging provides a larger metal-semiconductor junction area compared to the standard 40 Mil variant. This directly translates to:
- Better heat dissipation under continuous load
- Higher reliability in demanding power circuits
- Lower thermal resistance for improved long-term performance
- Ideal for high-density PCB designs requiring compact but powerful rectification
Applications
- DC/DC Converters & Switching Power Supplies
- Freewheeling Diode in Motor Drive Circuits
- Reverse Polarity Protection
- High-Frequency Rectification Circuits
- Secondary Rectification in SMPS
- ESC (Electronic Speed Controller) circuits
- Automotive Electronics
- Industrial Control Systems
- Communication Equipment
Package Details
The SMAF (Small Molded Asymmetric Footprint) package is an evolution of the standard SMA (DO-214AC) package, featuring a slightly different footprint that offers better board attachment and improved thermal performance — making it increasingly preferred in production-grade designs.
Product Highlights
- Clip-bonded leg structure for reduced electrical resistance
- Guard ring design for mechanical stress protection
- Equivalent to 1N5822 in SMD form
- Compatible with automated SMT pick-and-place assembly
- Tape & Reel packaging available for bulk orders
