Wafer-level MOSFETs perform in space-constrained applications

Nexperia has unveiled two MOSFETs in a DSN1006 package and a third in the  DSN1010 package which are claimed to save power and simplify thermal management in space-constrained applications.

The PMCB60XN and PMCB60XNE 30V N-channel small-signal trench MOSFETs are claimed to have market-leading RDS(on). The compact wafer-level DSN1006 package makes energy go further where space is tight and battery runtime is critical, said Nexperia. 

The MOSFETs are suitable for miniature electronics like smartphones, smart watches, hearing aids and earphones. The MOSFETs have RDS(on) up to 25 per cent better than competing devices, said Nexperia, to minimise energy losses and increase efficiency in load switching and battery management. The performance also reduces self heating which enhances user comfort in wearable devices.

The PMCB60XN and PMCB60XNE have maximum RDS(on) of 50mOhm and 55mOhm respectively, at VGS = 4.5V. This gives them the lowest on-resistance per die area among similar 30V MOSFETs in the market, claimed Nexperia. The PMCB60XNE comes with ESD protection rated to 2kV (human body model – HBM) integrated in the tiny 1.0mm x 0.6mm x 0.2mm DSN1006 outline. Both MOSFETs are rated for drain current up to 4.0A. 

The third MOSFETs is supplied in the DSN1006 package. The PMCA14UN is a 12V, N-channel trench MOSFET. Maximum RDS(on) is 16mOhm at VGS = 4.5 V for the PMCA14UN which is supplied in the SOT8007 outline, measuring 0.96 x 0.96 x 0.24mm.

The 30V PMCB60XN and PMCB60XNE, and 12V PMCA14UN, are in production now and available from Nexperia. 

Nexperia claims to produce components that are required by every electronic design in the world. The company’s portfolio includes diodes, bipolar transistors, ESD protection devices, MOSFETs, GaN FETs and analogue and logic ICs. 

Headquartered in Nijmegen, the Netherlands, Nexperia annually ships more than 100 billion products, meeting the stringent standards set by the automotive industry. 

The company has employees across Asia, Europe and the USA. Nexperia is a subsidiary of Wingtech Technology and has an extensive IP portfolio and is certified to IATF 16949, ISO 9001, ISO 14001 and ISO 45001.
