New ASFETs Provides Enhanced SOA Efficiency

These new Software Particular MOSFETs supply enhanced security in opposition to in-rush currents and can be utilized for hot-swap functions.

Sizzling-swaps shield the primary bus of the gadget from in-rush currents. These in-rush currents usually create reliability challenges for hot-swap functions. Nexperia has launched hotswap software particular MOSFETs (ASFETs) with enhanced Delicate Working Space (SOA). The brand new units mix industry-leading enhanced SOA efficiency with extraordinarily low RDS(on), and can be utilized in 12 V hotswap functions together with knowledge middle servers and communications gear.

Nexperia has developed PSMNR67-30YLE ASFET, totally optimized for hot-swap and comfortable begin functions. The gadget delivers 2.2x stronger SOA (12 V @100 mS) than earlier applied sciences whereas having an RDS(on) (max) as little as 0.7 mΩ. The Spirito impact (represented by the steeper downward slope discovered on SOA curves at larger voltages) has been eradicated, whereas distinctive efficiency is maintained throughout the total voltage and temperature vary (in comparison with unoptimized units).

The gadget is characterised at 125 °C and supplies scorching SOA datasheet curves due to this fact supporting designers by eradicating thermally de-rate design. Nexperia has launched 8 new units (three 25 V and 5 30 V). These units can be found in a selection of LFPAK56 & LFPAK56E packages with RDS(on) starting from 0.7 mΩ to 2 mΩ, the vast majority of hotswap and comfortable begin functions are addressed. Two extra 25 V merchandise (which could have a good decrease RDS(on) of 0.5 mΩ) are deliberate for launch over the approaching months.
