Company Announcements

PLANO, Texas--(BUSINESS WIRE)--Dec. 17, 2025-- Diodes Incorporated (Diodes) (Nasdaq: DIOD) today announces an expansion of its automotive-compliant* bipolar transistor portfolio with the introduction of the DXTN/P 78Q & 80Q series. These ultra-low V_CE(sat) NPN and PNP transistors deliver industry-leading conduction efficiency and thermal performance, optimized for demanding automotive power switching and control.

The twelve high-performance devices support a broad voltage range, making them suitable for 12 V, 24 V, and 48 V automotive systems. They are ideal for gate driving MOSFETs and IGBTs, power line and load switching, low-dropout (LDO) voltage regulation, DC-DC conversion, and driving motors, solenoids, relays, and actuators. Rated for continuous operation up to +175°C, and offering high ESD robustness (HBM 4kV, CDM 1kV), they provide reliable operation in harsh automotive environments.

Housed in the ultra-compact PowerDI^®3333-8 package (just 3.3mm x 3.3mm), these devices cut PCB footprint by up to 75% versus traditional SOT223, freeing space for additional functionality. A large underside heatsink delivers ultra-low thermal resistance (R_θJL) of 4.2°C/W. The side-wall plateable (SWP) feature improves automated optical inspection (AOI) visibility and strengthens solder joints. This enhances quality assurance, reduces manual inspection, and supports efficient, reliable manufacturing.

Both series span BV_CEO ratings from 30V to 100V and deliver robust current handling. The DXTN/P 80Q series provides extra headroom for demanding designs, with continuous ratings up to 10A and peak pulse capability of 20A. Ultra-low saturation voltage (just 17mV at 1A) and an on-state resistance as low as 12mΩ minimize conduction losses, enabling cooler operation and higher efficiency. This helps designers cut conduction losses by up to 50% versus previous generations, reducing heat and easing thermal management.

The DXTN/P 78Q series is now available from between $0.19 and $0.21, and the DXTN/P 80Q is available from between $0.20 and $0.22; both in 6,000-piece quantities. Standard compliance versions, the DXTN/P 78 & 80 series, are also available and suitable for industrial and commercial applications.
