SMFA Asymmetric Series TVS for SiC MOSFET Gate Protection

December 6, 2024

The SMFA Asymmetric TVS Diode Series is designed specifically for SIC MOSFET gate protection for asymmetric voltages. It comes in SOD-123FL small and flat lead low-profile plastic package.

Applications

• AI/data center server power supplies
• High-efficiency power for EV Infrastructure
• High-reliability power supplies for semiconductor/ industrial equipment

Features & Benefits

• SOD-123FL low-profile package: maximum height of 1.08 mm
• Low inductance, excellent clamping capability
• For surface-mounted applications to optimize board space
• Typical failure mode is short from over-specified voltage or current
• Whisker test is conducted based on JEDEC JESD201A per its table 4a and 4c pass Class 1 and 2
• IEC 61000-4-2 ESD 30 kV(Air), 30 kV (Contact)
• Glass passivated chip junction
• Low dynamic resistance
• VBR @ TJ = VBR @ 25 °C x (1+αT x (TJ – 25)) (αT:temperature coefficient, typical value is 0.1%)
• Recognized compound meeting flammability rating UL94 V-0
• Halogen-free and RoHS compliant
• Pb-free E3 means 2nd level interconnect is Pb-free and the terminal finish material is tin(Sn) (IPC/JEDEC J-STD609A.01)
