200 V, 10-40 Amp Diodes from Power Integrations based on merged-PIN tech

Power Integrations has introduced the LQA200 series of 200 V diodes based on merged-PIN technology that offers ‘soft’ switching and low reverse recovery charge (Qrr).

Available from 10 A to 40 A in common-cathode configuration, these “soft” new 200 V diodes reduce peak reverse voltage, increasing voltage margin and enhancing operational reliability and ruggedness. The need for snubber capacitors is also reduced or even eliminated, which further improves efficiency and lowers cost. When compared with equivalent Schottky products, the Qspeed diodes reduce Qrr by up to 80%, and have a 45% lower junction capacitance, claims Power Integrations.

Comments Klaus Pietrczak, product marketing manager for Power Integrations: “Our new LQA200 diodes are suitable for use in power-supply output rectification circuits for hard- or soft-switching applications such as telecom power supplies and audio amplifiers. By reducing the levels of EMI produced, designers can save space and component cost as well as improve performance with a more elegant design.”

LQA200 diodes are available now in DPAK, D2PAK and TO-220 packages, ranging from $0.40 to $1.20 each in 10K quantities. For more details visit http://www.powerint.com/en/products/qspeed-family/q-series.
