Omm 36 mmho 3. See page 4 and BD data sheet. The group of figures indicates the typical operating voltage Vz for each type at the nominal operating current l z rating of the range.
The first subscript indicates the terminal which is positive with respect to the second subscript, eg.
A — detection diode, high speed diode, mixer diode. Example B2 In multiple unit devices the terminal subscripts shall be modified by a number preceding the terminal subscript. The effect of heatsinks of various thermal resistance and contact b1d31 is often included in the above chart.
When the mica washer is used, the compound must be applied to both sides of the washer. Each part is completely reviewed annually; revised and reprinted where necessary. BM m8X – P max.
A general relationship for the approximate second harmonic distortion, d 2gen- erated by current gain mismatch, is given by the expression: The BC is primarily intended for use in driver stages of audio amplifiers and in signal processing circuits of television receivers. Icm The maximum permissible instantaneous value of the total collector current. Three loci for critical current values are shown on the diagram; these represent d.

The thermal impedance curves for the BD are shown in Fig. Conversely, for complementary pairs with a higher gain, the resultant negative feedback is increased and a higher h F E ratio will maintain the necessary protection against distortion.

Small signal current gain linearity A. This curve is divided into two areas: If the current is allowed to increase up to a critical value at C the device will datashete second breakdown. Encapsulated in TO plastic envelope.

Due to the current dependency of V C e it is usual to present this information as a voltage rating chart which is a curve of collector current versus collector to emitter voltage see Fig. Actual pulse widths of 1. TO Collector connected to the metal part of the mounting surface 2. In the final column of Table 1values of instantaneous power are calculated and plotted against time in Fig.

Under these circumstances, the leads should be retinned using a suitable activated flux. It must however be understood that no guarantee can be given here regarding the availability of the various devices or that their specifications may not be changed before the next edition is datwsheet.
BE sat decreases by about 1.
Final Data The transfer from tentative data to final data involves the addition of those numerical values and curves which were not available at tentative data stage and small adjustments to those values already quoted in tentative data. TO-1 AC 9A m. Hole spacing in either type oi grid allows the insertion of the “Lockfit” pins; but as the holes of the closely spaced t-grid are necessarily of smaller diameter than those of the dwtasheet grid, the pins cannot be or should not be pushed in beyond the middle expansion – lock ‘A’.
