High power TVS diodes protect vulnerable electronics from voltage transients

23-09-2019 | Littelfuse | Semiconductors

Littelfuse has a new series of higher surge TVS Diode devices in a DO-214AB package. The 8.0SMDJ series is optimised to guard sensitive electronic equipment against transient voltage caused by lightning and other voltage events. Because it combines up to 8000W of peak pulse power dissipation in a compact SMC package, the series gives circuit designers a high-surge, space-saving circuit protection solution that simplifies PCB design and improves reliability significantly.


“Compared to other market solutions currently available, the new unidirectional and bidirectional 8.0SMDJ series TVS Diodes deliver higher surge protection in a small DO-214AB SMC package. It is ideal for DC12V, DC24V, and DC48V applications either by using single device or two in a series,” said Meng Wang, global product manager power TVS at Littelfuse. “The combination of a high power TVS diode in a compact footprint means circuit designers can conserve precious board space for design optimisation opportunities, including increased power density and higher production efficiency.”


Typical markets and applications for the diodes include data centres, industrial, home appliances, consumer electronics, AC and DC protection, PoE protection, and low-speed outdoor port protection.
