Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the 2N6037 is the 2N6034.The 2STF1340 (SOT-89), FMMT619 (SOT-23) and FZT690B (SOT-223) is the SMD version of the 2N6037 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2N6037 with the 2N6037G, 2N6038, 2N6038G, 2N6039, 2N6039G, BD187, BD189, BD675, BD675A, BD675AG, BD675G, BD677, BD677A, BD677AG, BD677G, BD679, BD679A, BD679AG, BD679G, BD775, BD777, BD779, KSE800, KSE801, KSE802, KSE803, MJE222, MJE225, MJE242, MJE800, MJE800G, MJE801, MJE801G, MJE802, MJE802G, MJE803 or MJE803G.The 2N6037G transistor is the lead-free version of the 2N6037.
