Shindengen Announcing the Launch of A Bidirectional TVSS Which Reduce Package Size by 30%, Contributes to Downsizing of ECU Protective Circuits for Vehicle Applications

技术问答

SHINDENGEN Electric Manufacturing Co., Ltd. has developed and begun shipping samples of the "DL20B Series" bidirectional TVSs.

In recent years, increasing functionality and complexity of vehicle application ECUs has led to an increase in energy consumption. In the past, reverse connection protection elements for ECU protection used general rectifying diodes, however recently the trend has shifted towards circuit configurations which use Schottky barrier diodes, MOSFET, ideal diodes, etc. to achieve higher efficiency. Demand for bidirectional TVSs, which can absorb positive and negative surges with a single element, is growing for these type of circuit configurations for surge protection and dissipation loss reasons. In these cases, significant space restrictions due to an increase number of ECUs in vehicle applications has led to more demand for compact bidirectional TVSs.

Shindengen has launched the DL20B Series bidirectional TVSs in response to these needs. Compared to equivalent products from other companies, this series has a 30% reduced package size which contributes to device downsizing and space saving.

Shindengen also offers a wide withstand voltage lineup, to allow customers to select products suited to the standards required for their particular applications. In addition, because these products use the same package as conventional uni-directional TVSs, there is no need to change board patterns, allowing for more flexibility in design.

■ Features

The package size is reduced by about 30%【Fig.1】
Package size reduced 30% compared to the conventional equivalent competitor products, contributing to product downsizing.
Utilizes a gull-wing structure for both anode and cathode terminals.【Fig.2】
Alleviates substrate stress while plating of the terminal tip provides higher reliability.
Uses the same package as uni-directional TVSs
No need to change board patterns when switching from uni-directional TVSs to bidirectional TVSs due to circuit changes
Wide withstand voltage lineup available
You can select products suited to required standards from a wide range of 23V to 27V withstand voltage

■ Typical Applications

vehicle application ECUs Overvoltage Surge Countermeasures（ISO7637-2）

■ Product Specifications

■ Availability

Around December 2023.

【元件】减少封装尺寸30％的双向TVS开始发售，为车载ECU保护用回路的小型化做贡献

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。
