Diodes & Thyristors (Si/SiC) Forum Discussions
Hello,
I implemented the spice model IDDD16G65C6_L1 in LTSpice, but it does not run.
I get this following message:
Did someone have this problem? How can I solve it?

Hi I have a quesiton on Qc test of SBD ,.
I am studying the test method , however , I find the different test methods between 650V SBD and 1200V SBD .The 650V SBD Qc test conditon :VR = 400 V, di/dt = 200A/µs, but in 1200V SBD datasheet , the Qc test conditon is calculated by capacitance from 0V to certain Voltage .I am not sure which test method is correct and now I am wondering the test method in 650V SBD , any specificaiton or jedec ,IEC could be referred?

Show LessI want to calculate conduction losses of Thyristor.
Since Thyristor conducted in Halfwave condition in alpha = 180[deg], I use some conditions like this :
I_avg = Ip / pi
I_rms = Ip / 2
Conduction losses = Vt0 * I_avg + R_D * I_rms^2
But I don't know how to calculate conduction losses in case of alpha is not equal to 180[deg]. (For example, alpha = 30[deg] case).
Thank you.
Show LessPlease tell us about the durability of IPD90P04P4L-04 printed plate bending.
Strain of 2,000~3,000 μST was confirmed in products produced in-house.
Because we want to consider whether or not it can be used as a non-defective product,
Please tell me how much strain the above elements can withstand.

Show Less在上百KW到数百KW的变频器,整流桥使用大功率二极管整流的,在我测量的一台大功率变频器,用万用表测量二极管的导通压降,正反测量都有压降怎么这是什么原因?但是我在正负母线上上直流电源,变频器能够正常开机,假设此时二极管击穿,那么一上电就会短路电源,但是此时电源正常,说明二极管没有被击穿,请问是什么原因导致的整流二极管正反测量都有导通压降?同样,IGBT在整机上测量正反也是导通的,续流二极管和IGBT都有导通压降,但是拆下来都正常,想请问这是什么原因?
Show LessWe purchased one of your MOSFET 650VCoolMOS ™CEPowerTransistor (model number is IPA65R400CE) is now used in our company's products, some time ago we do safety certification of our products, this MOSFET is recognized as a critical component, you need to provide the corresponding UL / VED certificate number, I'm in the certification website did not check this product, can you provide a thank you! I did not find this product on the certification website, can you provide, thank you very much!

Show LessThe recommended Ris resistance value to the IS pin of the IPD is 1 kΩ for BTS50010-1TAD and 1.2 kΩ for BTS70xx-1EPx. Is this constant mandatory? What is the usable range of Ris resistors?

Show LessDear IFXer,
Why we cannot found the Trr of IDH10G65C6 value in datasheet compare the Si Fast recovery diode?
there has any spec different? how to judgement the switching speed who is fast?
IDH10G65C6 show Qc and CT
Si Fast recovery diode show trr
