International Transistor Equivalents Guide (Bernard Babani Publishing Radio and Electronics Books) Paperback – 1 Mar. 1981

If you are seeking a transistor (transfer resistor) with a high PIV (Peak Inverse Voltage) for use in high-voltage work; or you are seeking a transistor with a wide bandwidth for use in radio transmitters and receivers and high-end amplifiers; or you are seeking to demodulate complex analogue and digital signals; or you are seeking fast switching properties for use in transmitters and switch-mode power supplies; or you require a ‘matched-pair’ of transistors for use in class B output stages or analogue computing, then THIS publication is for you.Inside you will find reference to all of the above types of transistor, together with their equivalents – all you need to know is the transistor by its MANUFACTURERS REFERENCE – such as BC109 (a low-noise low-power NPN device).What you WON’T find is the MEANING of the manufacturers’ CODE so here it is.The FIRST letter informs you that it is either a GERMANIUM transistor (‘A’) or a SILICON transistor (‘B’)The second letter informs you what the device is designed to do: ‘C’ denotes that the device is a low-power device for low frequency work - as opposed to ‘D’ which is a higher power device for high power applications – or ‘F’ which denotes a transistor with a wide bandwidth for high frequency functions.The last part of the code is the manufacturers’ SPECIFICATION REFERENCE – this points to a SPECIFIC Specification Sheet (spec sheet) that contains all of the TECHNICAL CHARACTERISTICS of a specific device, such as its internal lattice structure (i.e. PNP or NPN); its amplification characteristics (i.e. its HFE); its transient response time; its skew (recovery) rate; its maximum current carrying ability before it shorts-out; its base-emitter ‘cut-off’ voltage; its maximum switching speed before it fries; its current-to-noise profile; its current handling capabilities; its junction PIVs (i.e. its base-emitter and base collector junction zenner strike voltages); its collector-base capacitive characteristics for a given applied current range; and of course its logarithmic-transfer-resistor curve for a given applied current range (information that is essential if you are building an analogue computer); along with its PHYSICAL characteristics such as its physical dimensions; its footprint; its operating temperature range; its pin configuration; and its current-to-heat transfer curve.THIS publication does NOT provide technical data – it merely lists transistors with EQUIVALENT characteristics to the one you seek. If you require the technical information for a specific application then check out RS (Radio Spares) and other sources on the net.

It's in good condition for my son exactly what he wanted

Very comprehensive book, of transistor equivalents, but unfortunately it doesn't contain the information that I wanted.

for 1 penny + pp a real bargain, thanks

Essential book for constructors.

This isn't as good as the Towers guide (reviewed elsewhere) but as it's usually cheap it's worth adding to the workshop book shelf.

Very pleased.Thank you Seller.

A generally useful cross referencing of types, but lacking in details of voltages, ratings, etc. Would be useful for 'blind' selection of alternatives.
