OptiMOS™ power MOSFET in PQFN 8x6 package

PQFN 8x6 package - addressing the growing market need for high-performance, high current and high-power density applications

The new PQFN 8x6 is a high performance clip-based package optimized to handle very high currents up to 650 A, with significant increase in power density and a substantial reduction in footprint.

A footprint reduction of >50 percent compared to TOLL, together with a height reduction of 100 percent, results in an overall space saving of >70 percent enabling much more compact designs.

The seamless backward compatibility of this package with PQFN 5x6 enables power scalability of the same board or enable less paralleling of MOSFETs (ex: replace two PQFN 5x6 with one PQFN 8x6 solution).

Key features:

High current capability in a compact 8.0x6.0 mm² footprint
Industry's lowest R_DS(on) and FOM
Leadless package with ultra-low package parasitics (resistance and inductance)
Latest OptiMOS™ MOSFET technology
Footprint compatibility with PQFN 5x6

Key benefits:

Increased power density allows higher power designs in a compact board space
Very low conduction losses, low thermals and less device paralleling
Low EMI
Delivers benchmark performance with best-in-class power density and power efficiency
Simpler PCB design with scalability across various power levels

Potential applications:

Drones

Robotics

Multicopters

Light electric vehicles

Power and gardening tools

Battery management system (BMS)

PQFN 8x6 package performance

PQFN 8x6 is a power packed innovative package solution the fills the gap in package sizes between PQFN 5x6 and TOLL. It can achieve high power levels similar to TOLL and is very compact by being slightly larger than PQFN 5x6.

PQFN 8x6 target applications and demonstrated value

See application test results

The superior product performance of PQFN 8x6 was demonstrated by testing the industry-best IQFH61N06NM5 (OptiMOS™ 5, 60 V NL, 0.61 mΩ max) against best-in-class products available internally in TOLL IPT007N06NS (OptiMOS™ 5, 60 V NL, 0.75 mΩ max), PQFN 5x6 BSC012N06NS (OptiMOS™ 5, 60 V NL, 1.2 mΩ max) packages and competitor’s best-in-class PQFN 8x8 60 V NL solution during DC & Pulsed current tests.

We observe the new PQFN significantly outperforms competition by >30% allowing for cooler operation, enabling reliable operation and product robustness.

A 3-phase inverter testing to compare the performance of a single PQFN 8x6, IQFH61N06NM5 (OptiMOS™ 5, 60 V NL, 0.61 mΩ max) with two PQFN 5x6 in parallel, BSC012N06NS (OptiMOS™ 5, 60 V NL, 1.2 mΩ max) of similar performance was done on a combo board created to accommodate both products.

Results demonstrated similar performance for both combinations resulting in 27% reduction in overall board space when using PQFN 8x6.

Benchmarking conclusion

The DC and Pulsed current testing at below conditions were performed to mimic a locked rotor scenario.
