2004年10月13日 · Vce(sat) at a rating current gives you an indication of how efficient a power switch the device is. If the Rc is high you will have much more Vce(sat) under load. However …

2010年2月25日 · The Vce(sat) value varies with each transistor. It is stated in the datasheet and should be checked from there. eg. BC547 at Ic=10mA, Ib=0.5mA has Vce 0.09V to 0.25V, but …

2008年9月29日 · Why is Vce(sat) (Collector Emitter voltage of a transistor at saturation) constant (around 0.2V) for all transistors whatever be the biasing voltage, power handling, power rating, …

2010年2月25日 · Vce sat is the characterstic of the particular transistor. it is mentioned in datasheets. Rc and Rb are used to limit the collector current and base current respectively. the …

2008年1月19日 · Vce(Sat)= Vth + Ic*ESR is a linear approximation. for Ic=20mA Vth = 0.04V and for Ic=1mA Vth= 0.1V then slope of curve will determine actual voltage drop above threshold, …

2005年7月27日 · RC - It will determine where Vce(sat) will occur. Increasing RC will increase Vce(sat) and lowering RC will lower Vce(sat). Vce(sat) is the "knee" of the collector current, …

2012年1月6日 · Vce(sat) is roughly proportional to collector current. So, for your circuit, deduce Vce(sat) from the value closer to your 20mA load, that is, Vce(sat) for Ic = 150mA. Scale that …

2002年5月17日 · I want to protect IGBT from short circuit protection using Vcesat ,I want to use HCPL-316J optocouplers. My IGBTs are 1200V,100A. My question is : Vcesat turn off IGBT …

2025年1月14日 · Hi. I am looking to detect Vce(sat) voltage of IGBT for shootthough protection. The typical arrangement is as shown in the attachment. I want to detect the Vcesat of lower …

2014年5月1日 · The temperature coefficent of the Vce(sat) and Vbe are both negative [mV/°C] and vary with current. The collector emitter equivalent resistance rCE=Vce(sat)/Ic depends on …
