BC847BP in DFN1006 +++ "Budget" Devices: Example S1YL +++ MMBT7002DW - Two MOSFETs in SOT-363

The BC847BP is the first representative of a transistor in the tiny "No-lead" package DFN1006. The leads of this part are integrated into the bottom of the package, thus reducing the required space to a minimum.

"Budget versions" are parts being consequently trimmed for cost reduction. An example is the S1YL having 1A/2000V, being the budget version of S1Y. The cost reduction was achieved by shrinking the die size. The admissible surge current is then only 22/25A compared to the 30/32A of the S1Y. But if this matches with the requirements of the application, the S1YL is a cost effective alternative for the S1Y.

The MMBT7002DW contains two independent N-channel MOSFETs in a halogen-free SOT-363 package. Having 60V and 115mA per transistor, these parts can be operated at 5V logic levels.

KBPC pass RSH test +++ SPICE models of Top 500 +++ Diotec at electronica China +++ New Branch office in Shenzhen

Our KBPC bridge rectifiers with Fast-on connectors pass the "Resistance to Solder Heat" - test. These parts are UL recognized and can be found in the File E175067. You can find the information also in the data sheet with the related standards.

SPICE models of our Top 500 components are now available on our Homepage. The models are detailed and show realistic simulations. You can find the existing library of SPICE models directly through the article search, here for the article MMTL431A.

From 14th to 16th March 2018 we were part of the electronica China in Shanghai.

We are happy to announce that we opened a new Branch office in Shenzhen, China.

PCN033: Discontinuation of accessory part BO2

Discontinuation of accessory part BO2 due to too low demand.

Databook Edition 25 +++ Demoboard 3990 +++ Diotec.com data sheets +++ Diotec continues to produce what others discontinue

The "silver" Edition of our Databook is now ready to be printed. It contains the latest part introductions which were already presented in the 25th Selection Guide. Pre-order your personal printed version of the Diotec Databook directly here.

With great enthusiasm we announce the immediate availability of our demo board 3990. On our website you will find an application note for the demo board. Order your personal demo board here.

It often happens that customers rely on data sheets from popular internet platforms or search engines. Those data sheets are not subject to any update procedures and as such are not binding. We recommend to solely download data sheets from the Diotec website.

Diotec has a wide repertoire of components that can serve as an equivalent substitute for our competitors componets, for example the transistor BC817K. If you are unsure whether a Diotec component meets the same technical parameters  please contact our technical support directly.

15MQ040N immediately available +++ Top-Distributors awarded +++ Diotec not affected from Kobe Steel issue

Diotec has recently added the 1.5A/40V Schottky diode 15MQ040N in SMA package to its production program. This widely used article is currently very difficult to source from our competitors due to extremely long lead times. We are able to produce the 15MQ040N in a much shorter time. Order your samples here.

During our Diotec Distribution-Meeting from 11. – 13. October 2017 in Freiburg im Breisgau we awarded our “Top Distributors 2017”. Nearly all of our worldwide represented Distributors participated.

In the light of recent events, we would like to inform you that Diotec has never used, directly or indirectly copper sheets for semiconductor terminals from the supplier Kobe Steel. Please, have a look at our official statement.
