STMicroelectronics STEVAL-SID140V1→STEVAL-SID140V1
Isolated thyristors driver in AC solid-state-relay
The STEVAL-SID140V1 allows to evaluate insulated control of thyristors SCRs with the STSID140-12 driver.The STSID140-12 driver has a 40 mA of output current capability to drive SCR gate easily without any additional power supply in high voltage.The galvanic-insulated inductive barrier allows a 1250 V rms rating-insulated voltage, compliant for the application of functional insulation, and with a high creepage distance at 3.9 mm.Based on two TN5015H-8G SCR in back-to-back, this evaluation board is able to drive AC load connected on line up 4 Amps.
