bc303THE BC303, BC304 ARE PNP SILICON PLANAR EPITAXIAL. TRANSISTORS RECOMMENDED BC303 only. 85. V. Collector Cutoff Current. Emitter Cutoff Current.The BC303 is a bipolar junction transistor (BJT) with an PNP-type confuration. That means the BC303 transistor has a negatively charged layer between two positively charged layers. This
