Care must be taken to ensure good thermal contact between the transistor and heat sink.

The speach and music value is the output which will be obtained when peaks occur in low level passages. The transient thermal impedance curves are also included so that the operating mounting-base temperature can be calculated.

Unless otherwise stated, the con- tinuous value is implied. In second breakdown the device offers only a very low resistance to collector current, and is invariably destroyed if the current is not specially limited by a circuit external dztasheet the transistor.

Collector 1 All leads are insulated from catasheet case. Source Vns — — 6V: TO 3. E AV I, max. Type Polarity Outiline Maximum Ratings ‘tot h min.

These types belong to the family of extrusions which has been used with Mullard power devices requiring special heatsink considerations, such as thyristor stacks and power rectifiers.


The leads above this point should be fatasheet during any lead bending operations. The case temperature during soldering must not at any time exceed the maximum storage temperature. N-P-N Silicon planar types cont.

The collector lead must, in addition, be soldered to a copper area of at least 10mm x 10mm. Storage time is measured in the following circuit: Item 1 must then be mounted upside down. For a few variations the ae162 resistance may be derived as follows: 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 published.

The above method is not absolutely accurate, but the approximation errors in- volved are allowed for in the published data tolerances. The equation used is: Temperature Tmin. The second subscript denotes the reference terminal or circuit mode that the current or terminal voltage is measured. Thermal calculations The maximum permissible mounting base temperature is now determined as follows: Block 20 45 20 sd162 50 50 60 50 50 30 50 50 80 40 50 0.

This curve is divided into two datasheer When using a soldering iron, transistors may be soldered directly into the circuit, but heat conducted to the junction should if possible be kept to a minimum by the use of a thermal shunt.

Tentative Data Tentative data aims at providing information on new devices as early as possible to allow the customer to proceed with circuit design. Mounting of ‘Lockfit’ Transistors.


IMn first breakdown, or avalanche, the device goes through datashfet 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.

BTWR Silicon thyristor for ‘industrial’ applications. Without further qualification, the dc value is implied. Voltage ratings charts and permissible area of operation.

The efficiency of this clip or heatsink is measured in terms of its thermal resistance 6 h dagasheet expressed in degrees centigrade per watt deg. This example describes how the SOAR curves are used to check the suitability of the BD power transistors in a television audio amplifier application.

In this case the point P on Fig.
