Thyristor customer habit called SCR.
It is a kind of high power semiconductor switching devices, it is a lot of more phyletic, with ordinary thyristor
, bidirectional thyristor, fast thyristor and high frequency thyristor, etc.
Here introduces the most widely used ordinary thyristor.
A, ordinary thyristor conduction conditions: 1, the ordinary thyristor at specified temperature range, general -
10 ℃ to 60 ℃;
2, thyristor between anode and cathode on the forward voltage, and voltage amplitude should be at least more than 0.
3, between cathode and gate put forward voltage, voltage amplitude should exceed the trigger threshold voltage, must be greater than zero.
3 v, is commonly 3 ~ 10 v.
4, ordinary thyristor current flow, at least should be greater than the with current, and generally is to maintain the current 2 times;
5, the gate voltage on time, must more than open time, generally should be more than 6 mu s.
Ordinary thyristor blocking conditions: 1, the ordinary thyristor at specified temperature range, general -
10 ℃ to 60 ℃;
2, through the current of thyristor, must be smaller than maintain current;
3, keep the current through the ordinary thyristor zero time, must be smaller than the turn off time.
Zhejiang rectifier co. , LTD. , the production of various kinds of specifications models of thyristor module, modules, solid state relay, silicon controlled rectifier bridge arm module, rectifier bridge module, supporting various copper pieces and supporting module USES the aluminum radiator, and other products, sincerely look forward to cooperating with companies to provide affordable, quality and reliable electronic components.
