The ±5% tolerance on the nominal zener voltage means the regulation point sits between 4.085 V and 4.515 V at the test current — tight enough for most clamp and reference circuits in industrial and military-grade supplies. The 500 Ohm maximum zener impedance (Zzt) at the operating point is typical for a 4.3 V device at this power level — the dynamic resistance rises with lower zener voltages, so the regulation accuracy degrades with load current variation. These numbers confirm the diode behaves as a standard zener with a soft knee — the leakage at low reverse bias is negligible for most shunt regulator designs.","metaTitle":"Microchip 1N6635 Zener Diode, 4.3 V, 5 W, Axial","metaDescription":"Active-production 4.3 V zener diode from Microchip Technology. 5 W power dissipation, ±5% tolerance, -65°C to 175°C range.
