Description

The 2N708 is a silicon NPN switching transistor listed in the Agenda radioelectronistului (2nd edition, 1989) among the bipolar transistors made in Romania by IPRS Băneasa, in a TO-18 package [1].

The 2nd edition prints a single hFE value, 250. The 1st edition of the Agenda (1983) gives different characteristics for the 2N708: Vce sat = 0.15 V at IC = 10 mA, h21E = 50 at IC = 0.5 mA, VCE = 1 V, and fT = 480 MHz [3].

Coded as (JEDEC system) [2]:

Part Meaning
2 device with 3 electrodes (transistor, thyristor etc.)
N semiconductor device
708 identification number (01–9999)

hFE (h21E) measured at IC = 10 mA, VCE = 1 V; Vce sat at IC = 10 mA [1].
