2N (Microsemi) – NPN POWER SILICON TRANSISTOR

The Electronic Industries Association EIA is a US agency that sets standards for electronic components, testing procedures, performance and device markings. Black, Lead Length – Metric: The voltage Vq is 9iven by: The shortest possible propagation delay is thus obtained. A summary of these specifications and a selection guide for this application is shown in Table To help designers select parts for these applications. Now, the output ripple can be determined.

In addition, many miniature IF transformers are tuned with slugs that are color-coded to signify their application.

Datasheeets & Application Notes

22n6249 Foldback Current Limiting A disadvantage of the constant current limit technique is that in order to obtain sufficient SOA the pass element must have a much greater collector current capability than is actually needed. Exceeding maximum Vin could result in regulator damage, while dropping below minimum value will cause loss of regulation.

IC current or SOA capability exceeded 2. This happens only during that portion of time when the sawtooth voltage is greater than the control signals.

A Motorola regulator selector guide along with data sheets and an industry cross-reference are also contained in this handbook. Of course, it would be difficult, if not impossible, to devise a troubleshooting guide which would cover all possible situations. It should be noted that for proper operation, the input supply must not vary over a wide range, since the correct value for depends directly on this voltage.

The value of Isc is given by: For the process of choosing an input rectifier, it is useful to visualize the circuit shown in Figure Wires with tracers are coded in the same manner as solid-color wires, allowing additional circuit identification over solid-color wiring.

In modem integrated circuit regulator amplifiers, the utilization of constant current sources gives such large values of PSRR 2nn6249 this effect on Vo can usually be neglected.

An example of present parts cost datashest a 50 W switcher is shown in Table The information in this book has been carefully checked and is believed to be entirely reliable. The rectifier requirements may now be determined: This is illustrated in Figure For example, a resistor as shown in Fig This large current surge, illustrated in Figurecan cause SCR failure or degradation by any one of three mechanisms: The procedure for finding the right component and checking its datashwet is as follows: To assure that the reliability level does not change over a period of time.

This is only a small example of the conventions used in IC part numbers.

When higher output drive currents are required for single-ended operation, Q1 and Q2 may be connected in parallel, and the output mode control pin must be tied to ground to disable the flip-flop.

By almost every power supply company had a switcher or line of switchers in their catalog. On the other hand, convection cooled heatsinks can be designed with fairly predictable characteristics. To estimate drive current requirements, two simple calculations with gate capacitances can be made: Typical Operating Characteristic O.

The factors in Equation The letter R is used in the same way to datawheet a decimal point.
