The PN4248 is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, base, and collector leads.
Here is an image showing the pin diagram of this transistor.The KST5086 (SOT-23), KST5087 (SOT-23), MMBT5086 (SOT-23) and MMBT5087 (SOT-23) is the SMD version of the PN4248 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the PN4248 with the 2N3905, 2N3906, 2N4402, 2N4403, 2N5086, 2N5087, 2SA539O, 2SA539Y, 2SA696, 2SA696-C, 2SA696-D, 2SA696-E, 2SA697, 2SA697-C, 2SA697-D, 2SA697-E, 2SA708O, 2SA708Y, BC317, BC317A, BC317B, BC317C, BC320, BC320A, BC320B, BC320C, BC527-10, BC527-16, BC527-25, BC528-10, BC528-16, BC528-25, BCX79, HS733, HS733-BL, HS733-GR, HS733-O, HS733-Y, KN2907, KN2907A, KN3906, KSA539O, KSA539Y, KSA708O, KSA708Y, KSA733G, KSA733L, KSA733O, KSA733Y, KSP2907A, KSP55, KSP56, KSP8598, KSP8599, KTA539, KTA539-O, KTA539-Y, KTC9015, KTC9015A, KTC9015B, KTC9015C, KTN2907, KTN2907A, MPS2907, MPS2907A, MPS2907AG, MPS2907G, MPS3906, MPS4250, MPS4250G, MPS4354, MPS4355, MPS4356, MPS6516, MPS6517, MPS6518, MPS6534, MPS750, MPS750G, MPS751, MPS751G, MPS8598, MPS8598G, MPS8599, MPS8599G, MPSA55, MPSA55G, MPSA56, MPSA56G, MPSW51A, MPSW51AG, MPSW55, MPSW55G, MPSW56, MPSW56G, NTE159, NTE193, P2N2907A, P2N2907AG, PN200, PN200A, PN2905, PN2905A, PN2907, PN2907A, PN4249, PN4250, PN4250A, PN4354, PN4355, PN4356, S9015, S9015A, S9015B, S9015C, S9015D, SS9015, SS9015A, SS9015B, SS9015C, SS9015D, ZTX550, ZTX551, ZTX790A, ZTX792A or ZTX951.
