Resolved! STWBC86JR wireless charge efficiency
Hi,When we were using the STWBC86JR as the wireless charging TX, we encountered a problem. The design is defined as wirelessly charging the battery and supporting the product's operation. The tested charging efficiency was relatively low, only 43%. W...
Resolved! STWLC38 VRECT over-voltage clamping resistor
Hello experts, I have a question about how to determine the resistance value.In STEVAL-WLC38RX circuit schematic, R4 = 200, R5 = 200, R6 = NA.What is the idea behind the values you set?The electrical characteristics in the datasheet for STWLC38 state...

hello dearwe have this BULK ID, and i want to know wich is the DATA CODEcan you help meor i have to give you the trace code?
SPI EVAL6480H Rev1
Hello! I'm developing a project with the L6480H integrated circuit, using the EVAL6480H board for SPI communication. However, I have a problem: the L6480H only echoes the commands I send via SPI. Regarding the hardware, I soldered the jumpers JP1, JP...
Resolved! Maximum junction temperature for L78
Hello.I would like to know the maximum Tj value of L78.I think the junction temperature of silicon semiconductors is generally 150°C, but the data sheet states that the operating junction temperature range is 0 to 125°C for L78 and 0 to 150°C for L79...
Resolved! The difference between STTH20003TV1 and STTH20003TV
Hello Team，I found both STTH20003TV1 and STTH20003TV are available on the market.Unfortunately, I cannot find STTH20003TV1 in ST datasheet.STTH20003 - 300 V, 200 A Ultrafast Diode - STMicroelectronicsCould you provide the difference between STTH20003...
stpd01 self destructs at 15V
I am using a STPD01 in a design for USB PD. Neat little part but I'm finding during testing that setting 15V output on this part immediately causes it's internal switching FET that most be located near the PVIN/VCC pins of the package to self destruc...
Resolved! Identify this two terminal component
I'm trying to identify this two terminal components. It has these identifiers on it "CBJ GP 950", but there is a chance the GP is a 6P, but G looks correct. There are not cathode markings so I'm guessing it's not a diode, unless it's bidiretctional. ...
