MOSFETs with high SOA are for 48V telecomms
Preparing for 48Vhot swap telecomms systems, Alpha and Omega Semiconductor has released two 150V MOSFETs. The AOTL66518 and AOB66518L MOSFETs are characterised by a high safe operating area (SOA) capability, for reliable operation in hot swap applications.
The AOTL66518 and AOB66518L MOSFETs are supplied in a TOLL package, which has a footprint 30% smaller than a conventional TO-263 (D2PAK) option. In additon to the space savings, the MOSFETs also have low on-resistance and a maximum junction temperature of up to 175°C. To protect the load and ensure reliable operation, the MOSFETs limit high in-rush currents in soft-start, eFuse and other hot swap conditions.
The TOLL package is designed to reduce the number of MOSFETs used in parallel in telecomms designs. Its clip technology ensures a higher current capability with the AOTL66518, for example, exhibiting a very low thermal resistance from silicon junction to the bottom of the package case (Rthjc) compared to a device in a TO-263 package.
The reliable, robust linear mode performance MOSFETs meet the demanding requirements of telecomms applications, with high SOA and low on-resistance, says AOS.
The AOTL66518 and AOB66518L are immediately available in production quantities with a lead-time of 16 weeks.
