Automotive Load Dump Protection
Diotec offers TVS product families for load dump protection according to ISO 16750-2:2012(E), both for applications without central load dump limitation (according to standard Table 5, Test A) and for those with central limitation (Table 6, Test B).
The new 6.6SM8Z series with 6.6kW peak pulse power in DO-218AB is already available, it will soon be complemented by the 4.6SM6Z series with 4.6kW. Both versions are compliant to AEC-Q101. The 5KP represents an alternative in axial package, it allows up to 5kW at the usual rating with 10/1000µs pulses. Classical alternator rectifier diodes in pressfit housings are the BYZ35 and BYZ50, which we offer especially for the after sales market. They offer a suppressor characteristic and thus provide the central load dump protection.
GBU Bridge Rectifiers in Tube Packaging
From now on we offer the bridge rectifiers of the GBU series also packed in tubes. This form of packaging allows the automated feeding and assembly of the components, which saves time and costs. The previous bulk packaging form is still available; to order the bridges in tubes, simply add the suffix "-T" to the article number (e.g. GBU8M-T). Each tube contains 20 bridge rectifiers, which are then packed in boxes of 1000 pieces each. This is the minimum order quantity, also valid for the bulk packed components.
The GBU series from Diotec is available with output currents of 4A, 6A, 8A and 12A, and each with 50 to 1000V reverse voltage. As a special feature, the GBU12 offers a forward surge current capability of 270A at 50Hz half sine wave (10ms), which is a unique selling point in the market.
SRL1 Series - A 1 Amp Standard Rectifier in low Profile SOD-323 Power Package

New Application Note for Industrial Lighting Applications
Discover our latest application note for Industrial Lighting Applications. We offer a wide range of silicon based, power discrete components like diodes and bridge rectifiers. Additionally, we also offer a new product portfolio of MOSFETs and linear voltage regulators fitting perfectly into a broad range of industrial lighting applications.
As we all know, lighting is an essential element in our present world. It plays a decisive role in our daily lives, right from low power indoor lighting at home or offices, to mid and high power outdoor lighting, industrial and horticulture lighting systems. Lighting accounts for about 15% of global electricity consumption.
A new era came with the light emitting diodes (LED). They consume little electricity, are long lasting, versatile and contain no toxic substances. LEDs have been successful in replacing the traditional lighting sources like fluorescent, Halogen, HID lamps and in many other high density lighting applications. Other intelligent technologies such as digital lighting control systems and smart lighting solutions are emerging in the market, further ensuring an increase in efficiency, greater energy savings and thus lower the carbon emissions. The discrete components always provides flexibility in choosing the perfect matching based on the circuit requirements. By choosing the best suited semiconductor components in the design, power losses decrease and energy savings can be pushed even further. Hence, the selection of the right components can also boost-up the overall performance.

BYG23T: Diotec's Avalanche Rated 1300V Bootstrap Diode
Discover our bootstrap diode BYG23T in SMA package, well suited for high-side floating gate driver circuits. The major challenge here is to select a robust device with respect to high voltage peaks during low side MOSFET or IGBT turn-off, as well as forward surge currents during re-charging of the storage capacitor. High frequency operation is state-of-the-art in these applications.
The BYG23T features an avalanche rating of 5mJ with breakdown voltage of 1350V and a very low reverse recovery time of 75ns. Repetitive peak forward current rating is 3A, and average forward current 1A.
Various half-bridge gate driver circuits are currently available in the market with integrated bootstrap diodes. The total power dissipation of such gate driver IC is the combination of gate driver losses and the internal bootstrap diode losses. The difficulty with this circuit is the operation at higher frequencies and load capacitance applications, where the power losses in the internal bootstrap diode dominates the overall power dissipation.
An external bootstrap diode, even if in parallel with the internal one, can significantly overcome the problem of excessive power losses in the driver IC. A stand-alone operation is of course possible as well.
