For an npn, the baseemitter behaves as a forwardbiased diode and the basecollector behaves as a reversebiased diode. Unless otherwise specified in this data sheet, this product is a standard commercial product and is not intended for use in. Transistors amplify current, for example they can be used to amplify the small output current from a logic ic so that it can operate a lamp, relay or other high current device. The 2n3904 is a really common transistor that we use all the time and the 2n3906 is its pnp sibling. In this case the transistor is designed for low current operation so you need one with a similar gain at 1ma. Hackster is a community dedicated to learning hardware. Bc337 bc338 npn epitaxial silicon transistor mouser electronics. Mouser is an authorized distributor for many transistor manufacturers including diodes inc.

The operating characteristics of a transistor are all found on its data sheet. In data sheets and application notes which still contain nxp or philips semiconductors references, use the references to nexperia, as shown.
The guaranteed minimum value is given because the actual value varies from transistor to transistor even for those of the same type. In data sheets and application notes which still contain nxp or philips semiconductors references, use. Basic semiconductor physics, diodes, the nonlinear diode model, load line analysis, large signal diode models, offset diode model, transistors, large signal bjt model, load line analysis, small signal model and transistor amplification. The frequency is the the frequency at which the gain drops to 1, as long as the replacement transistor has enough gain at the frequency used in the circuit, it doesnt matter, as a general rule higher is better. Transistors are in stock with sameday shipping at mouser electronics from industry leading manufacturers. This page covers practical matters such as precautions when soldering and identifying leads.
