Customer: Business unit focusing on power electronics for electric vehicles (EV)
Product: Reverse polarity diode for electric vehicle (EV) application
Customer Need: A customer reached out to Diotec Electronics Corporation looking for a reverse polarity diode solution to withstand high forward current (1KA) EV applications. The reverse polarity diode needed to withstand 1KA within 2 seconds to support a 14V fuse in an electric vehicle (EV) car. The customer had previously tried connecting several small diodes in parallel to withstand the high forward current application, but it was not serving their technical requirements.
Solution: 1KA diode cell and BAR75xxD package for electric vehicle (EV) applications
Diotec Electronics Corporation specializes in designing diode cell and diode cell package combinations that serve our customer’s unique technical needs and offer the highest performance. Diotec Electronics Corporation’s recommendation for this customer is a combination of a super jumbo 1KA diode cell and the BAR75xxD diode cell package.
Super jumbo 1KA diode cell
Diotec Electronics Corporation’s super jumbo 1KA diode cell, which has a diode cell structure and form that is very much like the 75Amp surface mount diode cells (BAR75xxD), except the 1KA diode cell has a much bigger silicon die. The 1KA diode cell is made with a single round silicon die that is 1.00 inch in diameter, in comparison to the 75Amp diode cell with a smaller 0.250 inch diameter round die. This solution eliminates the shortcomings of using several small 75Amp diodes in parallel, which can result in overheating and diode failure.
The shortfall of smaller diodes arranged in parallel is that each smaller diode will have different electrical resistance. The vast majority of the electrical current often goes through only some of the diodes with the lowest electrical resistance, causing them to become overheated and overwhelmed, resulting in diode failure.
Diotec Electronics Corporation utilizes its proprietary vacuum soldering technology to ensure that dies are soldered to oxygen-free high purity copper (silver-plated) headers on both sides of the die, ensuring that there are no solder voids
BAR75xxD diode cell package
Diotec Electronics Corporation BAR75xxD diode cell package will allow the customer’s design engineers to design their product with the most efficient heat dissipation mechanism.
Technical design
Diotec Electronics Corporation partners with customers to brainstorm and design the optimal product design that allows for peak performance and optimal heat dissipation. Collaboration covered technical topics such as Bar bus design, soldering, and more.
