SiC Schottky diodes now come in DDPAK packages
Infineon Technologies AG expands its CoolSiC Schottky diode 1200 V portfolio by adding six devices in a D²PAK real 2-pin package. Using SMD packages, designs can be more compact and more cost-effective. Moreover, the new D²PAK real 2-pin package eliminates the middle pin to offer 4.7 mm creepage and 4.4 mm clearance distance. Compared to […]
Automotive load dump TVS devices offer best-in-class specs
The TLD5S/6S/8S Series of AEC-Q101 qualified high-power unidirectional transient voltage surge suppressors (TVS) are offered with ratings of 3.6 kW, 4.6 kW and 6.6 kW, and are ideally suited for critical load dump applications designed to protect on-board electronic devices from high voltage surges emanating from the alternator should the battery become disconnected. Offered in […]
Thin-film isolator material also helps manage heat
Fujipoly offers a large selection of thin-film, thermal interface materials. Available in eight formulations, these Sarcon materials offer versatility in managing heat dissipation while exhibiting useful characteristics such as electrical insulation, and UL94 VO flammability. The Sarcon series of thin films range in thickness from 0.15mm to 0.85mm. Depending on the material selected and application […]
Maximize piezoelectric transducer buzzer audio output with these driver circuits
One of the most common choices for audio communication between a product and a user is a buzzer. Piezo transducer buzzers are one such technology used for audible identification or alert, but unlike their indicator counterparts, transducer buzzers require an external driver circuit to produce a desired tone or sound. So, how does an engineer […]
