Diotec的 ESD9BL0522P 采用微型“无引脚” SOD-882 / DFN1006的封装。 在没有引脚封装的情况下，它的尺寸仅为1.0 mm x 0.6 mm，但引脚完全封装集成在底部。根据IEC 61000-4-2，该物料在任何情况下提供了舒适的ESD抗浪涌能力，分别为20 kV（空气放电）和15 kV（接触放电）。
由于它们的结电容非常低，仅为0.4 pF，因此非常适合于高频数据线转输接口。 5V的隔离电压可覆盖广泛的信号，钳位电压为12V的ESD保护器件在1A和8 / 20µs浪涌冲击下可以保护电路中电子元器件。
Jump Start a Combustion Engine from an Electric Vehicle? It works! And is the reason why also EVs need load dump protection
Though the main power train of electrical vehicles use a high voltage battery, all these cars have still the traditional 12 V battery on board. Reason is that most electronic and electrical systems in a car - lights, screen-wiper, infotainment etc. - are made for that voltage level. This battery is further used for the switch to connect and disconnect the high voltage system when the car is started or stopped. As such, EVs can jump start cars using a combustion engine - and also vice versa!
At that procedure, load dump protection becomes important. A load dump transient is the voltage surge generated when the battery is disconnected while the alternator is connected. This typically happens if a discharged car battery is powered up by a second one and afterwards jump leads are removed. The peak voltage of this surge may be as high as 120 V and the surge may take up to 400 ms to decay. It is typically clamped to 40 V in 12 V vehicles (cars) and about 60 V in 24 V systems (trucks).
Diotec's new application note "Automotive Load Dump Protection" describes suitable TVS diodes for surges according to "Test A" (elements for centralized suppression) as well as "Test B" (distributed protection of on-board electronics), all described in the standard ISO16750-2.
从电动汽车快速启动内燃机？ 有用！ 这也是为什么电动汽车也需要抛负载保护的原因
在此过程中，抛负载保护变得很重要。负载瞬间突降是指在连接交流发电机后断开电池连接时产生的电压浪涌。通常会发生这种情况，如果放电的汽车电池由第二个电池供电，然后跳线会被移除。此浪涌的峰值电压可能高达120 V，并且该浪涌可能需要长达400 ms的时间才能衰减。在12 V系统车辆（汽车）中通常钳位到40 V，在24 V车辆系统（卡车）中钳位到60V。
Diotec的研发的新应用 “汽车抛负载保护”中，描述了适用于浪涌的TVS二极管，所有产品都符合标准ISO16750-2 中“ Test A”（用于集中抑制的元件）以及“ Test B”（车载电子设备的分布式保护）。

Want to do automatic assembly of the Bridge Rectifier to the PCB as well? Here is the solution! S16MSD2 - Half Bridge in D²PAK allows for full PCB assembled Power Rectifier Stages
When it comes to power bridge rectifiers, design engineers have to go back to through-hole devices which first need to be soldered onto the PCB, and then screwed to an extra heat-sink. These are manual assembly steps, which cost time and effort and also bear the risk of potential failures.
Other power semiconductors such as MOSFETs or IGBTs and diodes for the PFC, converter and inverter stage or brake chopper, are widely available in SMD outlines like the well known D²PAK. They can be assembled fully automatic by pick&place machines and afterwards solder process, at high speed and with constant quality.
The S16MSD2 half bridge closes the gap which was up to now at the input rectifier stage. Two of these parts form a full bridge, which can be assembled in the same process step than the other power semiconductors. Like for those, cooling is done via the PCB metallization. So the entire power stage can be done in one time and with the same concept.

SMS560-3G is a 5A/60V Schottky offering a forward voltage drop which was only possible with 40V types up to now. It has less than 0.55V at 5A, and anyway, unlike other "low Vf" Schottky types a low reverse current of maximum 80µA at 60V.
This outstanding performance is realized by Diotec's 3rd generation chip technology. Compared to former generations, this is a reduction of almost 20% in forward drop and thus power losses. Junction temperature is further reduced by the thermally low resistive MELF package, where these parts are build in.
The SMS560-3G is ideal for polarity protection but also high power output rectification. The 40V type SMS540-3G with even lower Vf completes the product family.
