These readings were recorded every 20[xs through the complete cycle of xs. If the application condition just exceeds the selected SOAR curve, then linear interpol- ation between the family of curves used and the next lower duty cycle curves.

The same curves apply to— and — – dahasheet external capacitances are used. The results obtained are with a series resistance of C. Move horizontally to the left until the appropriate orientation either horizontal or vertical and the appropriate surface finish is reached.

Encapsulated in a TO-3 envelope. The definitions of the three systems accepted by the International Electro- technical Commission are as follows: Operation is allowed under all base-emitter conditionsprovided no limiting values are exceeded. The thermal capacity of the heatsink will be such that the transient effect of the power will be averaged.

Older devices on which datasheeet may still be obtained on request are also included in the index of the appropriate part of each book. Transistors may be dip soldered at a solder temperature of C for a maximum of 10 seconds up to a point 2mm from the seal.

Burrs or thickening at the edges of the four holes must be removed and the transistor bolted down on a plane surface. It is in the forward-biased mode of operation that the phenomenon of second breakdown has been extensively studied over recent years, and a method of presenting the Safe Operating ARea abbreviated to SOAR is now being published in Mullard data for power transistors. Mounting of ‘Lockfit’ Transistors.

If a discrete transistor is used, the collector will not be. Thus the functions of the three locks are as indicated in Fig. Electrical -V CBO max.

It is assumed that the electrical and time conditions are the fixed parameters of an application at the design stage, and that the thermal conditions can be most easily adjusted. Tentative Data Tentative data aims at providing information on new devices as early as possible to allow the customer to proceed with circuit design.

The BF is primarily intended for appli- cation in a forward gain controlled pre-amplifier in v. Thermal resistance between junction ‘ J m ‘ and ambient, the device mounted on a ceramic substrate of 7 x 5 x 0.

In many applications, however, the reverse-bias breakdown characteristics are also of importance. The transistor will enter second breakdown at a certain critical current value V CB0 Collector-emitter voltage Fig.


Dissipation and heatsink considerations The maximum total dissi given by the relationship: Voltage, current, power and thermal ratings. Example B2 In multiple unit devices the terminal subscripts shall be modified by a number preceding the terminal subscript.

The maximum permissible average value of the total base current. Ic av max The maximum permissible average value of the total collector current.

TO 3. IMn first breakdown, or avalanche, the device goes through a negative resistance region until a critical current value is reached at which point the collector-emitter voltage abruptly switches to a very low value in second breakdown.

ADM can measure the temperature of an external diode sensor or diode-connected transistorconnectedof a diode or diode-connected transistoroperated at a constant current, exhibits a negativesubstrate transistorprovided for temperature monitoring on some microprocessors, but it could equally well be a discrete transistor.

At the tip is a spade-shaped lock ‘B’ ; partway up is a tapered cross-piece lock ‘A’ that projects further left and right than lock ‘B’; and nearest to the body of the assembly is another cross-piece lock ‘C’ that extends even further left and right than lock A’.

The BC is primarily intended for use in driver stages of audio amplifiers and in signal processing circuits of television receivers.

QA 7. For such applica- tions transistors have been developed which permit excursions outside the VcEomax rating under specified conditions. Underthesecircumstancesthe leads should be returned using a suitable activated flux. Thermal resistance between junction and ambient, the device mounted on a ceramic substrate of 7 x 5 x 0. SOAR information, and construct the boundaries using the method fully described in the reference TP All Mullard data, including pulsed power ratings, assume the use of square waves and resistive loads.
