Issues Realting to How to Derate Transistors and Resulting Failures

There are two main pages in this section of the web site; How to derate Transistors by Temperature [Power x Temperature], and Diode Derating [Current x Temperature]. An interrelated page details how to read and Interpret Temperature Derating Curves, which works for diodes or transistors. One of the new pages covers component mounting consideration, as Lead Length vs Thermal Resistance [power dissipation for leaded parts]. This particular topic shows why lead length is an important consideration .......

Basic Oscillator Circuit using Two Transistors

Basic Oscillator Circuit using Two TransistorsThis is the schematic diagram of basic oscillator circuit which using two transistors. When two transistors and a couple of passive components are connected as shown in the figure, the circuit starts to oscillate. The frequency of oscillation can be adjusted by changing the values of either the resistor or the capacitor. For easier experiment, you may replace the resi.......

1.5V LED FLasher Using 3 Transistors

To make LED works, you need a voltage source that is higher than the LED?s forward bias voltage, and it?s higher that 1.5V (around 2V for red LEDs). Fortunately, now you can make a LED flasher circuit that needs only 1.5V or a single cell battery to work. Here is the schematic diagram of the circuit:The core of this LED flasher scircuit is a cap.......

Hobby Circuit - N-CH AND P-CH TRANSISTORS FORM PUSH-PULL DRIVER __ Circuit s designed by David A. Johnson, P.E.

This circuit can produce high speed output signals with fast rise and full times. The unique change pump action allows the voltage of the upper P-ch device to range from millivolts to hundreds of volts. The output current is only limited by the rating of the transistors. I have used this circuit beyond 2MHz........
