Nov 12, 2023 · ChatGPT tells me: To calculate the heat dissipation of a MOSFET without a heatsink, you can use the following steps: Calculate the RDS (on) resistance from the drop in voltage across …

Jul 30, 2025 · Hello, I’m working on a power electronics project using a single TO-220 MOSFET mounted on a RA‑T2X‑64E extruded heatsink (cylindrical shape with vertical radial fins). I’m aiming …

Jul 31, 2009 · The case is a much better heatsink overall, it is a matter of surface area. I've been known to use a sink a lot like yours, AND add a block of metal (some machining required via dremal) taking …

Nov 14, 2022 · First of all, take the semiconductor device under consideration and figure the thermal resistance from the junction to the case (usually given in data sheets). Next, figure in a small amount …

Jul 3, 2019 · I don't think nylon screws for attaching to a heatsink would be a good idea. You need to be able to apply plenty of pressure between the component and the heatsink which you can't do with a …

Mar 22, 2023 · Hello everyone, I am designing an electric box for an aircraft and I need to use a diode which require to add a heatsink. Overall dimension of the diode is (L x W) 92mmx22.6mm. I was …

Jun 2, 2022 · I doubt if the heatsink is being used to complete the circuit, that is normally done with the actual collector pin of the transistor. (but it is possible) But you can check the continuity between the …

May 27, 2010 · It works, but if and only if the heatsink is firmly connected to circuit ground, and the connection between the heatsink and the TO-220 tab is well made with star washers. The possibility …

Dec 12, 2021 · HI all, So i want to design a 12V 4A power supply. I am using the National Semiconductor Volt. Reg. Handbook from 1980, but section 8.3 isnt completely clear to me regarding …

May 8, 2024 · I was wondering about the heat sinks that we usually put on the devices that dissipate more heat. Aluminum heat sink are very common. But if we look at the thermal conductivity of …
