PCN032: Change of Package MUR420 ... MUR460

Change of case outline of MUR420 ... MUR460 into DO-201.

Short Leadtimes +++ Precision Shunt Regulator +++ Application Note Smart Meter +++ Spice Models and Step Files

Diotec offers many of its production range from stock or with a typical four to six weeks lead time. Just email us your requests and let us check how we can support your needs!

The MMTL431A is an Adjustable Shunt Regulator in SOT-23. It features a precise voltage reference with +/-0.7% and allows for constant voltage adjustment from 2.48V up to 36V at curents from 1mA to 100mA. Samples can be ordered here.

The new Diotec Application Note Products for Smart Meter explains the need for minimum 1600V input rectifier for their power stage and why an Avalanche diode must have less than 2000V in that place.

We provide close-to-reality SPICE Models for circuit simulation as well as STEP files for CAD modelling in 3D: Ask our Technical Support.

PCIM Europe +++ Selection Guide Edition 25 +++ Video about Protectifiers(R)

At PCIM Europe in Nuremberg we presented for the first time our new Selection Guide "Silver Edition" 25. This complete overview of Diotec's product portfolio comes in the new, handy A4 booklet format and offers an application page including QR codes for download of product videos. You can order the Selection Guide here.

Even proven things require sometimes a small "freshening up". The reworked Diotec website can now be used comfortably on your smartphone or other mobile devices. Try it out!

The Third Edition of our online video presentation series explains the need for free-wheeling diodes in battery powered tools and why Protectifiers® are the better choice compared to Schottky diodes.

ESD Protection Device +++ Video about LED Driver +++ 5000W TVS in SMC

electronica in Munich Diotec presented for the first time to the public the ESD Protection Diode ESD5Z. It comes in the ultra small SOD-523 package and offers ESD protection up to 30kV. Available parts have stand-off voltages of 3.3V, 5.0V and 12V.

The Second Edition of our online video presentation series addresses designers of LED Drivers for smart lighting applications. The video will be presented live at our stand A5.417. Visitors can further take flyers with printed-on QR codes and watch all of our videos any time on their mobile devices.

We start a new series of TVS diodes in SMC package with peak pulse power of 5000W at 10/1000µs pulses. First available are the bidirectional 5.0SMCJ24CA, and the two unidirectional versions 5.0SMCJ28A and 5.0SMCJ30A.

Presentations

In the First Video Edition you will learn how electric vehicles can be charged reliably by means of the DBI25-18A. These bridge rectifiers are further interesting for industrial power supplies operated on worldwide mains.

During electronica India in Bangalore we presented for the first time to the public the Superfast Efficient Rectifier MUR460L. This 4A/600V axial lead diode with optimized price/performance ratio comes with a trr of only 50ns at a forward voltage of 1.28V. It is used e. g. for the output rectification at very high frequencies.

Our Application Note shows at a glance the different outlines and explains, why Melf is better suited for high power ratings and the flatpack SMA for thermal cycle loads.
