Littelfuse, Inc. has introduced the 5.0SMDJ-FB series of TVS diodes to protect sensitive electronic equipment from voltage transients caused by lightning and other transient voltage events. The series delivers up to 15% lower clamping voltage over traditional solutions and maintains breakdown voltage above the reverse standoff voltage, ensuring reliable protection for increasingly sensitive downstream components such as next-generation DC/DC converters.

The new 5,000-W surface-mount solution in a DO-214AB package provides robust protection in harsh environments. The operating junction temperature range is -65°C to 150°C. It is a drop-in replacement for the legacy 5.0SMDJ Series with the same compact DO-214AB (SMC) footprint. It meets IEC 61000-4-2 ESD 30 kV(Air) and 30 kV(Contact) and is recognized to UL 497B as an isolated loop circuit protector.
The lower clamping voltage via Littelfuse’s foldback technology enhances circuit protection performance in TVS components including I/O interfaces, VCC bus and other vulnerable circuits used in telecom, computer, industrial, and consumer electronic applications specifically for power over Ethernet (PoE) systems, AI and data center servers, ICT equipment power supplies, and industrial DC power distribution.
The 5.0SMDJ-FB TVS diodes are available in tape and reel format in quantities of 3,000. The are RoHS-compliant and halogen-free. Samples may be requested through Littelfuse’s authorized distributors.
