SS34 SMD Diode SMAF 50 Mil

SS34 SMD Diode – SMAF Package, 50 Mil | 3A 40V Schottky Barrier Rectifier

The SS34 SMD Diode in SMAF 50 Mil package is a high-performance Surface Mount Schottky Barrier Rectifier designed for modern PCB applications where space efficiency and fast switching are critical. With a chip size of 50 Mil, this variant offers superior thermal handling compared to standard 40 Mil or 45 Mil chips.

 Key Specifications

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
