Linear Voltage Regulators - Stable Output Voltage at Low Costs
Linear voltage regulators are simple and cost-efficient devices, for generating stable output voltage from a wide range of higher input voltages. With their simple 3-pin internal configuration and small package dimensions, they enable the designers to easily use them in various linear circuits covering a broad range of applications.
Our new linear voltage regulators are designed for high performance operation. Applications include medium power general-purpose consumer and industrial circuits such as DC/DC converters, battery chargers, LED drivers and µController (MCU) circuits.
Linear voltage regulators are used in sensitive applications and complex circuits, requiring stable supply voltages, low to medium current capabilities and low noise. You can find all the information also in our new flyer.

Protect your PV Modules and Improve Inverter Efficiency with our High Efficient and Robust Discrete Power Solutions in TO-220 and D²PAK
Solar energy is one of the cleanest forms of renewable energy. Photovoltaic plants are one of the fastest growing sources for our future electricity generation.
In PV modules, cell strings are connected in series to increase the voltage output. During operation, they require the protection from a "hot-spot" phenomena in case of partial shading. Bypass diodes come into play to overcome such problems. These diodes are connected in parallel to the strings and bypass the current from the shaded cells.
IGBTs used in solar inverters require free-wheeling diodes with low forward voltage drop and very fast reverse recovery, in order to keep power losses at a low level. Superfast Efficient rectifiers are a cost effective solution for all such inverters.
Diotec offer various high efficient and robust discrete power solutions like Schottky, Superfast Efficient and Protectifiers® in TO-220 and D²PAK packages.

全面受保护的设备让你一劳永逸
ESD保护器件不再受尺寸困扰
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
Protectifiers®-额外提供安全性和低功耗
尽管电动汽车的主要动力传动系使用高压电池，但所有这些汽车仍配备了传统的12 V电池。原因是汽车中的大多数电子和电气系统（灯光，雨刮器，信息娱乐系统等）都是针对该电压水平而制造的。当汽车启动或停止时，该电池还用于连接和断开高压系统的开关。因此，电动汽车可以使用内燃机来启动汽车，反之亦然！
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）。
