Power Integrations’ New 200 V Qspeed Diodes Combine Low Recovery Losses and Softness to Optimize Efficiency and Minimize EMI
Power
Integrations (Nasdaq: POWI),
the leader in high-voltage integrated circuits for energy-efficient
power conversion, today introduced the LQA200
series of 200 V diodes. The company’s Qspeed™
high-performance silicon diodes are based on merged-PIN technology that
offers ‘soft’ switching and low reverse recovery charge (Qrr). This
unique balance of features enables high-frequency operation and permits
the use of small, inexpensive magnetic components while maximizing
operational efficiency.

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.
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, please
