The DIODES Advantage

Drive automotive designs with Diodes’ DXTN/P 78Q & 80Q

series, delivering high efficiency, robust reliability, and

space-saving innovation for next-generation power

solutions.

Ultra-Low VCE(sat) NPN and PNP Bipolar Transistors Maximize

Power Density and Efficiency in Compact Automotive Designs

▪ Superior Efficiency

Ultra-low VCE(sat) (down to 17mV) and low on-state resistance

(down to 12mΩ) minimize conduction losses, reducing heat

and improving overall system efficiency

▪ Compact, High Thermal Performance Package

PowerDI3333-8 saves up to 75% PCB space versus

SOT223 and delivers ultra-low thermals for cooler operation

▪ Broad Application Range

30V–100V and up to 10A continuous current (20A peak),

ideal for 12V, 24V, and 48V automotive power systems

▪ Enhanced Manufacturing and Quality Assurance

SWP feature improves AOI visibility and joint strength

▪ Automotive-Compliant Reliability

+175°C rating and strong ESD protection ensures

dependable performance in harsh environments

Applications

▪ MOSFET and IGBT gate drivers

▪ Load switches

▪ Linear voltage regulation

▪ DC-DC converters

▪ Motors, solenoids, relays, and actuator control

DXTN/P 78Q &

80Q Series

Diodes Incorporated (Diodes) introduces

the automotive-compliant* DXTN/P 78Q &

80Q series of ultra-low VCE(sat) NPN and

PNP bipolar transistors.

The twelve devices, covering 30V, 60V,

and 100V ratings, deliver exceptional

conduction efficiency and thermal

performance for demanding automotive

power switching and control.

Suitable for 12V, 24V, and 48V systems,

they support applications including

MOSFET and IGBT gate driving, load

switching, LDO regulation, DC-DC

conversion, motor and actuator control.

Rated to +175°C with high ESD robustness

(HBM 4kV, CDM 1kV), they ensure reliable

operation in harsh environments.

The compact PowerDI®3333-8 package

(just 3.3mm x 3.3mm) reduces PCB

footprint by up to 75% versus SOT223 and

offers ultra-low thermal resistance

(4.2°C/W).

Side Wall Plateable (SWP) technology

improves AOI visibility and solder joint

strength for efficient and reliable

manufacturing.

With BVCEO up to 100V, continuous current

to 10A (20A peak), and saturation voltage

as low as 17mV, these transistors minimize

conduction losses by up to 50%, enabling

cooler, more efficient designs.
