DBI25-18A +++ Free-Wheeling Diodes +++ AEC-Q101 "compliant"

PCIM Europe we informed ...

... about AEC-Q101 "compliant" products.
... how "cool" DBI25 Three Phase Bridges stay under load and how to overcome a potential design gap when circuits have to fulfill EN61000-4-5 surges.
... why Protectifiers® are the perfect choice for Free-wheeling Diode Applications.

DBI25-18A: Next Generation Three Phase Bridge Helps to Solve Design Challenge

varistors for input voltage surge protection. Such varistors have a clamping voltage of typically 1650V, making the industry standard 1600V input bridges working at or even over the limit. This challenge can be managed by using the next generation three phase bridge DBI25-18A by Diotec. Its 1800V Vrrm provides a comfortable safety margin, allowing for reliable operation of industrial power supplies and frequency inverters.

The parts itself will be introduced to public the first time during electronica China and PCIM. Samples can be ordered now and will be shipped from May onwards.

200W TVS and 1A Fast Recovery in SOD-123FL, 150V Schottky in SMA/B/C

Selection Guide 24 comes with some new products which have been introduced the first time in the new data sheet layout. The SMF5.0...220CA are TVS diodes having 200W peak pulse power in the 1.3mm slim package SOD-123FL. In the same package is the Fast Recovery rectifier the FRL1A...M, having 1A and 50...1000V. These parts completes that exisiting outline family. The 150V Schottkys round out the type families SK32SMA...SK315SMA (3A in SMA), SK52...SK515 (5A in SMB) and SK82...SK815 (8A in SMC).

Flicker-free driving of LEDs / Design of Input Rectifiers

our visitors how only three components can provide a flicker-free driving of LED arrays directly on the 110/230V mains - see also our application note. The audience of our presentation on the PCIM forum learned more about the state-of-the-art design of input rectifiers.

New Devices in SOT-363

On electronica China in Shanghai we introduced our new devices in SOT-363 package:

electronica: Axial Diodes with Reduced Taping Width

Save the amount of lead wire which you will need to cut away! Our axial diodes, with reduced taping width, protect the environment by reducing the amount of waste material you will have to dispose of. As a bonus, they also save money up front because the shorter lead parts are priced less than the longer lead version!

The reduced taping width of 38mm (instead of 64mm) is available on request for components in DO-41 and DO-15 such as:

  • Zener diodes ZPY or ZY series
  • TVS diodes P4KE/BZW04 and P6KE/BZW06 series
  • The SB3H150 3A/150V Schottky diode

New Data Book and Selection Guide Ed 24

  • Schottky Diodes 150V and up to 175°C Tj
  • 3000W Pppm TVS Diodes
  • Axial Diodes having 25A and up to 2000V
  • Schottky Diodes in Power SMD having 5/10/15A
  • Superfast-Efficient Rectifier having 1/4/8A etc

The Selection Guide is available for down load at this link.
