Bookmark or Share- Bridge Rectifier & Heatsink Choice | All About CircuitsVrip = 1.418V (28,200uF Bank @ 50Hz full bridge so is 4A/2*50*0.0282 = 1.418V) Vout Min = 13.85V. Iload = 4A. Equiv Load resistance 13.85/4 = 3.463Ohm. Using the Capacitor Voltage equation, Vt = Vmax*e^ (-t/RC) Vt is 13.85, Vmax is 15.268, RC is 0.0976. Some rounding errors, but ive calculated that the time for the RC to discharge from Vpk to ...
- TO-92 Heat Sinks - All About CircuitsDoes anyone know of any cheap and readily available ones or a good DIY substitute? I guess you could give it an aluminum foil crown. There are better methods but this is inside a closed up tight linear RF amplifier with a finned aluminum heatsink for a case without any internal airflow cooling. Planing on adding some exterior muffin fans.
- Design Heat sink for Bridge Rectifier GBU/GBJ/GBP Packages7.5Ax1.1V = 8.25W power dessipation. Thermal Resistance for Heat Sink = ( (100 Degree C (Tjmax) - 50 Deg. C (Ambient))/8.26) - 3 (Resistance for Case to Sink) = 3 Deg. C/W. But, I cannot find for suitable heat sink for GBJ or GBU anywhere. Please advise me of whether above calculation is correct. How could I find the heat sink for GBJ or GBU ...
- How to mount heat sink to mosfet | All About CircuitsThe best mounting method is a spring clip pressing the body of the device against the heat sink. The benefit is that the force does not back off, and the metal part of the transistor does not bend. Read the application notes about heat sinking and mounting them. There is a whole lot of great information there. christiannielsen SamR.
- Heatsinks, mylar washers, thermal paste, safety... - All About CircuitsOkay, presently when i need to put a heatsink on a TO-220 vreg or whatever, i have simply used some mylar washers for electrical isolation. I was always a bit weary about this practice from a safety standpoint, however. For example, say i have a high voltage regulator and i am using a heatsink with mylar washers.
