The 2N1309 is the p-n-p complement of the n-p-n type 2N1308. Jedec TO-5 Outline Nr 3. Terminals 1 - emitter, 2 - base and case (!), 3 - collector. This type is identical with the type 2N1303 except the following items: VCE sat (IB = -0.13 mA, IC = -0.5 mA) -0.2 V max VBE (IB = -0.5 mA, IC = -10 mA) -0.15 to -0.35 V Collector to emitter Reach-Through Voltage Vrt -15 V min Static Forward Current Transfer Ratio: VCE = -1 V, IC = -10 mA hfe 80 min VCE = -0.35 V IC = 200 mA hfe = 20 min Small Signal Forward Current Transfer Ratio Cutoff Frequency VCB = -5 V, IE = 1 mA fhfb 15 MHz min -------------------------------------------------------- The 2N508 is not in this Manual, has obviously been manufactured by another company. OK? 73 Ha-Jo, DJ1ZB "MIKE REID" schrieb: 2N13092N508 Two old transistors that I have and can not find a datasheet for them. Can anyone help? Thank you, Mike WE0H WD2XGI EN35hj
