So, in case of an npn- device, only the LED connected to the base lead glows. However, in case of a pnp- device, the other two LEDs are lit. Thus, depending upon the orientation of the transistor leads in the test socket, we would get one of the six hexadecimal numbers taking LED connected to termi- nal 1 as LSB , if we consider all higher bits of the byte to be zero. The hexadeci- mal numbers thus generated for an npn and pnp transistor for all possible orien- tations six are shown under columns 5 and 6 of Table I.

We may call this 8-bit hexadecimal number base identification number or, in short, base-Id. Comparing the base-Id, generated with Table I, a microprocessor can easily indicate the type npn or pnp and the base of the device under test, with respect to the test socket terminals marked as 1, 2, and 3.

These numbers are applied sequentially to the leads through the testing socket. Collector identification.

Now, if the transistor is bi- ased as above, but with the collector and emitter leads interchanged, a current of much reduced strength would still flow in the C-E path. So, by comparing these two currents, the collector lead can be easily identified. Schematiccircuitdiagramofthetransistorleadidentifier tions.

As a result, the LEDs con- nectedtothecollectorandemit- ter leads start flickering alter- nately with different bright- ness. By inserting a resistor in series with the base, the LED glowing with lower brightness can be extinguished.

In the case of an NPN de- vice under normal biasing condition , conventional cur- rent flows from source to the collector layer. Hence, the LED connected to the collector only would flicker brighter, if a proper resistor is inserted in series with the base.

On the other hand, in case of a pnp device under normal biasing condition , current flows from source to the emitter layer. So, only the LED connected to the emitter lead would glow brighter. As the type of device is already known by the base- Id logic, the collector lead can be easily identified. Thus, for a particular base-Id, position of the collector would be indi- cated by one of the two num- bers we may call it collector- Id as shown in column 7 of Table I.
