RF Transistors Forum Discussions
I'm using the BFPxxx RF transistor to build a GHz-RF oscillator. I've been trying to extract the parasitic capacitance (Cbe, Cce) and resistance (Rce) values. When I extracted the frequency response of Cbe and Cce, I noticed a resonance at around 6 GHz. This means that after the resonance frequency (6GHz), the parasitic capacitance value becomes negative. Additionally, I found an extremely large negative resistance when extracting Rce at 1 GHz. I was wondering if you've also encountered this issue of self-resonance and negative capacitance, and if you have any suggestions on how to address this problem.
Thank you for your help in advance!Show Less
Screen printing issues with BCR08PNH6727XTSA1 Is the direction of arrival screen printing reversed from the direction of the specification screen printing?Show Less
We are looking to replace diodes for alternators within the creys power plant. The diode models we currently have in place are:
-IR45L100: rotating diode for direct conduction excitation
-IR45LR100: rotating diode for reverse conduction excitation
You provided us with these diodes, do you still produce them?
Regarding the alternator, it is a brushless rotating exciter: a small 6-pole alternator with induction and rotating armature.
The characteristics of the alternator are detailed below:
-Type: EDR 380/140
-rated power: 20.812 kVA
-nominal voltage: 122.1V
-Power factor: 1
-rated current: 98.4A
-degree of protection: IP23
-Constructive form: A4
-Excitation voltage: 57.8V
-Excitation current: 5.74A
-Connection of the rotary rectifier: Graetz bridge
-Diode with direct polarity: IR 45 L 100
-Reverse polarity diode: IR 45 LR 100

How to decode the datecode for BFR181WH6327. base on datasheet is YM but the symbols shows "1=", unable to decode the "=".
How much can the Vbe Ic curve vary lot to lot for the BFP196, a std dev plot would be good. Also a plot of the Vbe vs Ic would be good to see, also at the same Vbe how much would the collector current be different for two devices?
Hope you are doing well !!
We are going to use DSL70E6327HTSA1 in our design of IO Controller.
We would like to see a surge test performed on DIO pins and make sure the added TVS diodes would provide enough protection against surges.
This is very critical to verify the field failures and this needs to be added on test plans.
Can you please share documentation related to test setup of the surge testing ?
I couldn't find FIT report or any information concerning FIT or MTBF value for BFP420 bipolar transistor. How Can I get the best guess for this product?
Would like to check on this part (BAT62-09S) of RF Mixer and Detector Schottky Diode is still available or had been obsoleted?
