Hi Sir / Madam
Need your help, regarding part no. IRLI2910PBF, What is prefix Y on the body marking.
Top marking :
Line 1 : IRLI2910
Line 2 : IR logo Y837A
Line 3 : 6453
Regards

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?
