Part Number: ESM740G, ESM740
Function: 300V, 3A, Thyristor
Package: TO-202 Type
Manufacturer: ST Thomson, STMicroelectronics
This is 300V, 3A, Thyristor, SCR.
The Thyristor brings the best compromise between a fast turn off time and a low gate trigger current for applications where fast switching and sensitive control is requested.
