技术问答

新电元工业株式会社开发TVS“DL20B系列”并已开始出样。

近年来，随着车载ECU的功能增加和复杂化，功耗也随之增加。以前为保护ECU所需的防反接元件使用的是普通整流二极管，但最近为提高效率而转向使用肖特基势垒二极管、MOSFET、理想二极管等的回路结构。在这样的回路结构中，基于浪涌保护和减少损失的角度，通过单个元件吸收正负浪涌的双向TVS的需求正在扩大。其中，由于车载ECU增加导致的空间限制问题尤为突出，因此需要紧凑型的双向TVS。

为了满足这样的需求，新电元工业发售了双向TVS“DL20B系列”。该产品与其他公司的同类产品相比，封装尺寸减少了30％，有助于实现机器的小型化和节能空间。

另外还拥有宽耐压范围的产品阵容，可根据适用标准选用的产品。此外，由于使用与传统单向TVS相同的封装，因此基板布线无需变更，可实现更灵活的设计。

■ 特長：

封装尺寸减少约30％【图1】：
与之其他公司同类产品相比，封装尺寸减少约30％，有助于产品的小型化
正负极两端子采用鸥翼结构【图2】：
通过缓解基板应力及引线前端部电镀处理，实现了高可靠性贴装
使用与单向TVS同样的封装：
由于回路变更，需要从单向TVS改为双向TVS时，无需变更基板布线
拥有宽耐压范围的产品阵容：
23V～27V的宽耐压范围，必能找到符合适用标准的产品
