Two automotive transistors control matrix LED light clusters

Two automotive-compliant PNP transistors from Diodes control matrix LED light clusters. OEMs can use the ZXTP56060FDBQ and ZXTP56020FDBQ dual PNP transistors to migrate to adaptive LED headlights and dynamic turn signals based on LED technology. To meet this industry trend, requires dense and highly power-optimised transistors for shunting LEDs in matrix lighting and sweeping indicator applications.

The ZXTP56060FDBQ and ZXTP56020FDBQ address this demand with an optimised solution for controlling LED strings. They are AEC-Q101 qualified with very low VCE(SAT). They offer 60V (ZXTP56060FDBQ) or 20V (ZXTP56020FDBQ) breakdown voltages while delivering a continuous collector current of 2.0A. The ZXTP56020FDBQ has a maximum VCE(SAT) of 200mV at an LED current of 700mA, which minimises power dissipation and lowers operating temperature to improve lifetime and system reliability. It also offers a maximum power dissipation of 2.47W to reduce the size of the overall design.

ZXTP56060FDBQ and ZXTP56020FDBQ are manufactured in IATF 16949-certified facilities and are compatible with the Automotive Industry Action Group’s production part approval process (PPAP). The devices are supplied in the compact DFN2020 package (measuring 2.0 x 2.0 x 0.6mm).

Diodes provides semiconductors for the consumer electronics, computing, communications, industrial, and automotive markets. Its product portfolio consists of discrete, analogue and mixed-signal products and leading-edge packaging technology. The company has 28 sites for worldwide operations that include engineering, testing, manufacturing and customer service.
