Problem with estimating the number of TVS diodes in the clamping circuit
I am designing a clamping circuit for an IGBT driver such as ABB 5SNA 0600G650100.Between the collector and the IGBT gate there will be a set of TVS diodes with a Schottky diode at the end. The gate will have a 6.8k pull-down resistor to the emitter ...
Overvoltage suppresion by clamping circuit in IGBT driver
I am designing clamping circuit for IGBT driver. The max voltage is 4800V. I was thinking about using STTH112A diode. In the datasheet, there is no information about thermal resistance - junction to ambient for SMB or SMBflat version. How can I asses...

STDRIVE101 PWM maximum frequency
Hello, What is the maximum input PWM frequency of the gate driver, STDRIVE101, and its evaluation board, EVALSTDRIVE101? It does not say on the manuals.
L6562AT
Hello Now I am gonna design 120W flyback switch power with L6562AT, I have read through the datasheet, But still don't know how to fixed the value of resister and capacitor around L6562AT; Is there any paperwork about how to design wit...
L4984D - overvoltage
Hello, I am testing my second design with L4984D, the first one I designed work fine, but this second board breaks the FETs and I think that is due to overvoltage when I turn on the power. Could anyone tell me why that could be?Thanks
Marking on regulator L7805CDT-TR
Hellowhere can i find a document witch explain the marking on the regulator L7805CDT-TR Thank you
Resolved! Heating on VIPER22ADIP-E
Hi STMicroelectronics team,I am using VIPER22ADIP-E to design 15V, 5W power supply with input supply of 230Vac with diode bridge rectifier.The schematics file is attached here,When i am loading it with 5W load, the IC VIPER22ADIP-E is get heated and...
SPV1050 -- best way to switch input power between low impedance source (USB) and high impedance sources (Solar, RF, TEG)
In my application I want to be able to charge a low mAh battery using the SPV1050's built in battery charging functionality (in buck/boost mode), but I want the ability to switch the energy input from a high impedance source (such as Solar), over to ...
