ProTek Devices announced the general availability of two new surface-mount transient voltage suppressor (TVS) diode module series aimed at automotive, wireless base stations, Ethernet, industrial and other applications.
Housed in a low-profile two lead DFN package, the SM3KWxxA and SM5KWxxA series TVS diodes are designed to protect equipment and systems from the damaging effects of high voltage spikes.
The SM3KWxxA features a DFN package size of 6.5x5.5x1.2mm and the SM5KWxxA series of modules feature a DFN package size of 7.7x6.6x1.2mm. These packages make the SM3KWxxA and SM5KWxxA series TVS diode modules also well-suited for densely populated PC boards where smaller modules are required, offering the same protection as through-hole components.
The 24 Volt SM3KWxxA's DFN-2-3KW, in a plastic case package configuration, provides a lower profile at a reduced cost. It provides 3,000 Watts of peak pulse power dissipation for a 10/1000µs waveform.
The SM5KWxxA series features three modules with varying voltage. The SM5KW10A is 10 Volts; the SM5KW33A is 33 Volts; and the SM5KW36A is 36 Volts. The devices are rated at 5,000 Watts peak pulse power using the 10/1000µs surge waveform and 28,000 Watts for the 8/20µs surge.
Both series meet the requirements of IEC 61000-4-5 (Surge), 48A Level 3(Line-Ground), Level 4(Line-Line) and Level 1(Power). Other features include unidirectional configuration and easy mounting to printed circuit boards (PCB). They are both fully RoHS and REACH compliant.
Applications include: relay drives; motor (start/stop) back EMF protection; module lightning protection and secondary lightning protection.
Pricing: Starts at less than $1.00 in quantities of 10,000 or more.
