SM3000: Outstanding Reliability and High Performance when Lightning Strikes

SM3000

Designers of Smart Meters, LED Street Lamps, 4G/5G BaseStations, EV Charging Systems and similar applications often face the issue of over-voltage transients, since all these devices are connected directly to the land line which is highly affected by lightning strikes. They are affecting the reliability and lifetime of these products, so the use of rectifier diodes with extra high safety margin against transient surges is mandatory.

The SM3000 by Diotec is especially developed for these applications. It offers an impressive reverse voltage of 3000 V, an average forward current of 1 A and comes in a single SMD Melfpackage. Due to the large clearance and creepage it can replace the usual series connections, which are still common for input rectification at the above applications. You will find more detailed information in our actual flyer.

Features

  • SMD Melf package
  • Repetitive peak reverse voltage of 3000 V
  • Average forward current of 1 A
  • Replaces series connections

SKM14

The SKM14 is a 1 A / 40 V Schottky diode offering a forward voltage drop of less than 0.35 V at 1 A. It comes in the compact SOD-123FL package and measures only 3.7 mm x 1.8 mm. The very low profile height of 1.0 mm makes it well suitable for any mobile, slim but yet high performing electronics. This device is optimized for battery powered systems, where high energy savings are desired, e. g. for LED headlights.

Its low junction capacitance makes the SKM14 further suited for high frequency, energy efficient applications. This includes battery chargers, offline power supplies, set-top boxes, smart meters, any kind of smart home devices, DC/DC converters and many more.

Features

  • SOD-123FL package
  • Repetitive peak reverse voltage 40 V
  • Low forward voltage of < 0.35 V at 1A
  • Ideal for battery powered applications

Did You Ever Drive an Electric Car?

Discrete Solutions for EV Charging
Flyer EV Charging Solutions

When driving an EV, you will be impressed by its surpassing acceleration. More controversial discussed are the environmental aspects. Clear is that there is no pollution at the place where you drive. But if electricity for re-charging the battery is generated in the traditional way, the problem is just shifted to another place. New concepts deal with the usage of EVs for energy storage of fluctuating solar and wind power. Wall boxes or, even better, wireless charging systems at home and in companies could ideally serve such concepts.

All kind of EV charging stations can be easily realized by using cost-effective, widely available discrete power components. At low power systems they can be used to build the entire power stage, while at high power charging stations they are mainly used for auxiliary functions and controls.

Our latest flyer introduces a broad range of discrete power semiconductors from Bridge Rectifiers over Fast Efficient Diodes and MOSFETs to Schottky Rectifiers. It further includes state-of-the-art components used for control and protection purposes. They allow design engineers to develop cost-effective and energy-efficient solutions for any EV charging system.
