SP721電路保護(hù)的TVS-混合技術(shù)規(guī)格書PDF中文資料

SP721屬于電路保護(hù)的TVS-混合技術(shù)。由力特公司制造生產(chǎn)的SP721TVS - 混合技術(shù)混合技術(shù) TVS（瞬態(tài)電壓抑制器）產(chǎn)品族中的產(chǎn)品屬于過壓保護(hù)產(chǎn)品，其中結(jié)合了基于多種技術(shù)的保護(hù)機(jī)制，例如串聯(lián)連接的 MOV（金屬氧化物壓敏電阻）和 GDT（氣體放電管），旨在同時(shí)獲得低漏電流和自恢復(fù)箝位工作特性。

The SP721 is an array of SCR/Diode bipolar structures for ESD and over-voltage protection to sensitive input circuits. The SP721 has 2 protection SCR/Diode device structures per input. There are a total of 6 available inputs that can be used to protect up to 6 external signal or bus lines. Over-voltage protection is from the IN (Pins 1 - 3 and Pins 5 - 7) to V+ or V-.

The SCR structures are designed for fast triggering at a threshold of one +VBE diode threshold above V+ (Pin 8) or a -VBE diode threshold below V- (Pin 4). From an IN input, a clamp to V+ is activated if a transient pulse causes the input to be increased to a voltage level greater than one VBE above V+. A similar clamp to V- is activated if a negative pulse, one VBE less than V-, is applied to an IN input.
