Bourns PTVS High Current Power TVS Diodes are high current bidirectional TVS diodes designed for use in AC line protection and high power DC bus clamping applications. These devices offer bidirectional port protection from 58V to 470V, and RoHS and UL compliancy, while also meeting IEC 61000-4-5 8/20μs current surge requirements. The use of silicon technology in the Power TVS products generally offers lower clamping voltage under surge than competing MOV technology. Bourns High Current Power TVS Diodes are provided in through-hole packages and meet industry standard requirements such as RoHS and Pb Free solder reflow profiles.

TVS Diodes

Bourns Surface-Mount TVS Diodes are low capacitance devices that provide ESD, EFT, and surge protection for external ports of electronic devices such as cell phones, handheld electronics, and other portable electronic devices. Bourns TVS Diodes include smaller chip diodes that have the capability to provide a silicon diode with minimal packaging overhead. The chip diodes 0603, 1005, 1408, and 2010 are leadless, allowing for maximum space on PCB layouts. All Bourns diodes are RoHS compliant and meet many worldwide industry and government regulations on lead-free components. TVS package diode design kits are also available from Bourns.

適合RS-485接口的氣體放電管

Bourns氣體放電管(GDT)適合RS-485接口，專為符合RS-485接口界面的行業標準而設計，可在高雜訊和嚴格的電氣環境下提供電路保護。對於可能出現大量和快速的瞬衝電流，而又不容許出現故障的外露線，建議使用三段式Bourns保護系統。此系統包括TVS二極管 (CDSOT23-SM712)、TBU™裝置(TBU-CA065-100-WH)以及一個或以上的GDT。每個裝置都提供獨特的保護功能。經採用此分層式保護方案後，TVS陣列獲得TBU裝置的全面保護，而TBU裝置則完全受到快速的GDT保護。 浪湧保護的限制僅在於GDT本身的性能。Bourns GDT適合RS-485接口，能承受極高電流，並與TBU裝置協調合作來提供極快的電壓保護，同時也保護TBU裝置在觸發後免受過高電壓破壞。

PTVS高電流功率TVS二極體

Bourns功率瞬態電壓抑制器（Power Transient Voltage Suppressor，簡稱PTVS）產品是高電流雙向TVS二極體，設計用在交流線路保護和高功率直流匯流排的箝位應用中。這些器件提供58V至470V的雙向端口保護。這些二極體符合RoHS規定，通過UL認證，並符合IEC 61000-4-5 8/20μs電流浪湧要求。這些Bourns功率TVS產品所用的矽技術，與MOV技術相比，在浪湧下的箝位電壓更低。這些器件提供有通孔和SMD封裝樣式，並符合無鉛焊料回流焊曲線要求。SMD封裝相較同等通孔器件在峰值箝位電壓上減少20%，因爲其引線電感更低。

Circuit Protection Devices

Bourns manufactures and supplies a wide range of circuit protection technologies, including fuses, PTC thermistors, varistors, GDTs, resettable thermal cut-offs, surge protection devices, hybrid protectors, discrete semiconductor solutions, and more. Reliable surge protection is a critical design consideration to help ensure operational reliability of consumer electronics, industrial/communication equipment, automotive, battery charging, energy storage infrastructure, and renewable energy harvesting ecosystems.
