The tentative data may not include all the characteristics or ratings which will be incorporated later in the final data and some of the numerical values quoted may be slightly adjusted later on.
Care must be taken to ensure good thermal contact between the transistor and heat sink.
New Jersey Semiconductor
The sustained music value is the equivalent sinewave power output which will be obtained during sustained high level passages of music. Thus a closer approximation to the true conditions is necessary. At point B the device dataheet into avalanche, otherwise known as first breakdown. QA 7.

Thus, the transistor will not fail through second break- down even when the amplifier is continuously overdriven. The equipment manufacturer should design gd131 that initially and throughout life no absolute maximum value for the intended service is exceeded with any device under the worst probable operating conditions with respect to variations in supply voltage, environment, equipment components, equipment control adjustment, load, signal or characteristics of the device under consideration and of all other devices in the equipment.
Care should be taken not to bend the leads nearer than 1. V BE decreased by approximately 1. The selected total dissipation should be the maximum attained by any tran- sistor in the design being checked. The above method is not absolutely accurate, but the approximation errors in- volved are allowed bd113 in the published data tolerances.

The first two values constitute a useful measure of the power output capability of the circuit. A simultaneous display of the Vce and Ic waveforms is then obtained by connecting the probes of a dual- trace oscilloscope in the manner shown in Fig. The BCY87 and 88 are intended for applications in the pre-stages of differential amplifiers, where low offset, drift and noise are of prime importance.
Tentative Data Tentative data aims at providing information on new devices as early as possible to allow the customer to proceed with circuit design. Special care must be taken to ensure that thermal runaway due to excessive collector leakage current does not occur in this condition.
Emitter current ratings l E max The maximum permissible emitter current. Thus the functions of the three locks are as indicated in Fig.
Burrs or thickening at the edges dtasheet the holes must be removed and the transistor bolted down on a plane surface. J ‘ 7Z E’ The gain control performance of the BF is modified by these additional components and the combination is re- garded as an ‘equivalent trans- istor’ See the curves on pages 8 to 14 Fig.
This nomogram should not be used where forced air cooling is employed, or where heatsink material other than aluminium is desired.
The maximum permissible continuous value. The maximum total dissipation, P, max. Dissipation and heatsink considerations The maximum total dissi given by the relationship: The devices on which full data are given in these books are those around which we would recommend equipment to be designed.

The transistor has a very low feedback capacitance and is primarily intended for use in the output stage of television video i. CM I n max. Collector to emitter voltage ratings Vce max The maximum permissible instantaneous voltage between collector and emitter terminals. For information on the individual types reference should be made to the relevant data sheets.
The maximum total dissipation, P max. The traces of Vce and Ic taken from the oscilloscope are shown in Fig. Delay time Rise time Storage time Fall time 0. Continue this light pressure until both the ‘B’ locks of the rear two leads are inside the holes.
The thermal resistances required bc131 given assuming these lower dissipations. The circuit configuration is shown in Fig. If a discrete transistor is used, the collector will not be.
