Maximum zener impedance (Zzt) is 25 Ohms at the test current — a moderately low dynamic resistance that keeps the voltage regulation within a few hundred millivolts across the rated load current swing for a 500 mW part. Forward voltage drop is 1.1 V maximum at 200 mA forward current — useful if the diode is also used as a low-current rectifier or flyback clamp in the same BOM position. ## Package and board-fit — DO-35 axial form factor Supplied in bulk — no tape-and-reel — so the part is typically handled in low-volume assembly, prototyping, or rework where a cut-tape or individual tube presentation is preferred.","metaTitle":"Microchip 1N6003C Zener Diode, 13 V, 500 mW, DO-35","metaDescription":"Active production 13 V zener diode, 500 mW, ±2% tolerance, DO-35 axial package. -65°C to 175°C range.
