The ±5.68% tolerance on the zener voltage is tighter than the common ±10% grade, making it a candidate for applications where the regulation threshold needs to stay within a narrower window — shunt regulators, overvoltage clamps, or reference rails where the 22 V point is a design target, not a guard band. Maximum impedance (Zzt) is 14 Ohms at the test current; this is the dynamic resistance the zener presents in the breakdown region and factors into the regulation accuracy under load variation. ## 1 W in a DO-41 — derating and mounting The 1 W power rating is the absolute maximum at 25 °C lead temperature; above that the allowable dissipation derates linearly. In practice, the DO-41 axial body relies on the lead length and PCB copper area to conduct heat away — a short lead bend into a through-hole pad with a decent copper plane gives the best thermal path. Junction temperature is rated to 175 °C, which is the standard ceiling for silicon power zeners in this package class — it allows headroom in high-ambient environments like a power supply bulk rail or an industrial 24 V bus clamp. The reverse leakage is specified at 10 µA maximum with 17 V applied across the junction — a useful check when the zener is used in a standby or low-power circuit where leakage current matters. ## Lifecycle and compliance ROHS3 compliant — no lead, mercury, cadmium, or restricted phthalates in the bill of materials. No stock-holding claim — each lot quoted per the BOM quantity.","metaTitle":"HZ22BP-E Zener Diode, 22 V, 1 W, DO-41, Active","metaDescription":"HZ22BP-E Zener diode, 22 V nominal, 1 W max, DO-41 axial package, ±5.68% tolerance, 175°C junction rating.
