Rated for 500 mW continuous power dissipation in free air; the DO-35 glass body relies on the lead length and board copper to sink heat, so derate if the ambient exceeds 50°C or if the leads are trimmed short. Maximum zener impedance is 25 Ohms at the test current — this sets the dynamic resistance the load sees, which matters if the diode is used as a shunt regulator rather than just a protection clamp. ## Temperature range and leakage Reverse leakage is specified at 100 nA maximum at 9.9 V reverse voltage, which is 76% of the nominal zener voltage — this gives a clean knee region for low-current biasing. ## DO-35 axial package and reel format Through-hole mounting with 0.020-inch diameter leads; the glass body is hermetically sealed, so it survives humid environments and conformal coating processes without parametric drift.","metaTitle":"Microchip 1N6003B/TR Zener Diode, 13 V, 500 mW, DO-35","metaDescription":"Active 13 V zener diode in DO-35 axial package. 500 mW power dissipation, ±5% tolerance, 25 Ohm max impedance.
