The BF173 is a silicon transistor made by IPRS Băneasa, one of the representative export products of its section 2500 in 1980–1985 [1]. In 1980–1985 section 2500 of IPRS exported 30% of its output by value – over 10 million components – without quality complaints; its representative export types were the 1N148 and BA244 diodes and the 2N2369A, BF173, BB126, BC171, BC172, BC173, BC174, 2N2222, 2N2222A and BF458 [1].
