Alpha and Omega Semiconductor Announces New High SOA MOSFETs for 48 V Hot Swap Telecom Applications

Alpha & Omega AOTL66518 AOB66518L

Alpha and Omega Semiconductor announced the release of, AOTL66518 and AOB66518L, a 150 V MOSFET with low on-resistance and a high Safe Operating Area (SOA) capability designed for demanding applications in Telcom Hot Swap.

Alpha & Omega - AOTL66518, AOB66518L

AOS designed these MOSFETs with a low on state resistance and a robust linear mode performance with a wide Safe Operating Area (SOA) to manage Telecom’s demanding application where performance, reliability, and quality are essential. AOTL66518 and AOB66518L have a max junction temperature up to 175 °C and protects the load by limiting high in rush currents in soft-start, eFuse, and Hot Swap application conditions.

AOTL66518 delivers high robustness with a 150 V MOSFET in a TOLL package. The TOLL package offers a 30% smaller footprint than a TO-263 (D2PAK) package and has a higher current capability due to clip technology. AOTL66518 has a very low thermal resistance from silicon junction to the bottom of the package case (RTHJC) compared to TO-263. These features enable Telecom designers to reduce the number of in parallel.

Pricing and Availability

The AOTL66518 and AOB66518L are immediately available in production quantities with a lead-time of 16 weeks. The unit price for 1,000 pieces is $4.5618.
