It is OK to apply a voltage higher than 6.4 V to the B terminal. Increasing the input voltage only brings the BRT into deeper saturation (i.e., decreases VCE(sat)). This causes the base-emit...
Many scientific and graphing calculators may be capable of some of these functions: Switching from the usual base-ten to other number systems (hexadecimal counting, is a base-16 system) Using scientific notation to calculate very large numbers Using logarithms and trigonometric functions directly ...
Figure 1 Basic BRT circuit The power dissipation of a BRT is the sum of the power dissipated by the internal transistor (Q) and the built-in bias resistors (R1and R2). Here, let’s calculate the power dissi...

1. Solid grasp of basic electronics Knowing basic electronic principles, circuit board components and their behavior is crucial. You must also understand the basic physics and mathematics concepts to calculate parameters like impedance, signal timing, and power distribution. ...
Do not add the DLE and ILE together to calculate the maximum error that may occur at any digital step. The maximum error values specified in the device datasheet are the worst error values measured in a laboratory test environment over the given voltage and temperature range (refer to...
4 - Normalized Current Transfer Ratio (saturated) vs. Forward Current The following design example illustrates how the normalized curves can be used to calculate the appropriate load resistors. Example 1 Using the VOL617A-3 optocoupler with a CTR range of 100 % to 200 % at a forward current...
How to Calculate the Emitter Current Limiting Resistor in Parallel BJTs It is actually very simple, and could be calculated using Ohm's Law: R = V/I, Where V is the supply voltage used in the circuit, and "I" could be 70% of the transistor's maximum current handling capacity. ...
BRT通常用作开关。理想情况下,其导通电压(集电极-发射极电压,VCE)应尽可能接近零。 为达到该条件,应考虑基极电流。 为使VCE最小化,在图1所示的饱和区中使用了BRT。通常,双极晶体管被认为可保证hFE=100。但是,...
Now that the desired collector current has been found, you can calculate the final component value. RC is calculated using Kirchhoff's voltage law, drawing a loop through the base-emitter junction of the transistor and the shunt resistor. See Equation 5: (5) You can assume that IBRB is ...
