MOS with superior performance has now been widely used in electronic ballasts, energy-saving lamps were. But power MOS test screening, matching problem. It is difficult due to a lack of corresponding inspection means that many enterprises do not have to engage seriously in quality control as well as the effect of product consistence and reliability. The equipment in a unique program designed to solve the power MOS test problem containing micro-processing, intelligent a few significant simple application.
• Test parameters and ranges:
1) threshold voltage UGS (th): 0.1~9.9V
2) internal resistance RDS: 0.1~ 9.9Ω
3) transconductance gm: 0.30~5.00S
4) withstand voltage U (BR)DS: 50~650V
• Freely setting limit of qualification judgement, automatically saving in case of any power cut, and alarming when measured value exceeds limit
