The 130 V nominal breakdown voltage targets higher-voltage rail clamping or reference applications where a standard 5 V or 12 V Zener won't reach. Maximum impedance (Zzt) is 1.4 kOhms at the test current — this sets the dynamic resistance the regulator sees. A 130 V rail with a 1.4 kOhm impedance means the output voltage shifts about 1.4 V per mA of load change, so the diode is best paired with a series resistor that limits current variation. The 100 nA reverse leakage at 84 V (65% of Vz) is low enough for most bias and clamping circuits. ## Active production — no end-of-life concern The DO-35 package (also known as DO-204AH) is a through-hole axial leaded format. It mates with standard 0.025-inch diameter holes on a 0.200-inch lead spacing — a common footprint for hand-assembly or wave-solder lines. Tolerance is ±10% on the nominal 130 V Zener voltage — the actual breakdown sits between 117 V and 143 V. For a precision reference, a tighter tolerance variant (e.g., 1N6027B at ±5%) would be the better fit; for general clamping or transient suppression the ±10% band is adequate.","metaTitle":"1N6027A Zener Diode, 130 V, 500 mW, DO-35","metaDescription":"Microchip Technology 1N6027A Zener diode, 130 V nominal, 500 mW, ±10% tolerance, DO-35 axial package.
