Take another look at what you are trying to replace, post more info, schematic and/or photo, and maybe we can figure out what this is. timmy 11-16-2024, 12:02 PM Transistors are not made as variable capacitors and would not be primarily rated in pF. Take another look at what you are trying to replace, post more info, schematic and/or photo, and maybe we can figure out what this is. I’m trying to find a transistor with a higher pf rating to substitute for a varicap. I have read this can be done with using only 2 legs of the transistor. old_tv_nut 11-16-2024, 03:08 PM https://www.rf-microwave.com/en/itt-semiconductors/bb329a/varicap-diode-32v-2-5-35pf-do-35/bb329a/?srsltid=AfmBOopCXi4sfElK6c3PX3g382WowamuRE7_l2jUb a2ghHkXQErA7xD_ This was just a quick search - you may be able to find another source if you look.

A lot of semiconductor devices display that behavior when diode connected but only varactors are purpose built for that and rated so you know what the capacitors behavior will be. |
