* Bidirectional versions are UL approved under component across the line protection, ULV1414 file number E108274 (1.5KE200CA, 1.5KE220CA)
+ Underwriters Laboratory Recognition for the classification of protectors (QVGQ2) under the UL standard for safety 497B and file number E136766
for both uni-directional and bi-directional devices
Application
• This series of Silicon Transient Suppressors is used in applications where large voltage transients can permanently damage voltage-sensitive components.
• The TVS diode can be used in applications where induced lightning on rural or remote transmission lines presents a hazard to electronic circuitry
(ref: R.E.A. specification P.E. 60).
• This Transient Voltage Suppressor diode has a pulse power rating of 1500 watts for one millisecond. The response time of TVS diode clamping action is
effectively instantaneous (1 x 10
-9
seconds bidirectional); therefore, they can protect integrated circuits, MOS devices, hybrids, and other voltage sensitive
semiconductors and components. TVS diodes can also be used in series or parallel to increase the peak power ratings.
白光LED光衰原因之荧光粉性能的衰退 到目前，白光 LED、尤其是小功率白光 LED 的发光性能快速衰退已越来越为人们所认识。其实，盲目地夸大宣传，只能将 LED 行业引向歧途，不正视白光 LED 存在的问题，只能延缓白光 LED 应用的发展。只有正视问题、研究问题、尽早解决问题，白光 LED 才能健康、快速发展。 白光 LED 当前面临的一个主要问题就寿命问题。由于白光 LED 的价格尚很...[详细]
