The ±5% tolerance on the Zener voltage means the actual breakdown sits between 58.9 V and 65.1 V — tight enough for most rail-clamp and reference applications in this voltage class. Reverse leakage is specified at 50 nA maximum when biased at 47 V, so the diode draws negligible current below the Zener knee. This matters in low-power bias circuits where every nanoamp counts. Maximum impedance (Zzt) is 125 Ohms at the test current — a moderate dynamic resistance that keeps the voltage regulation within a few hundred millivolts under varying load current. ## Package and temperature reach Surface-mount SQ-MELF (B case) — the cylindrical body with wrap-around metallised end caps gives good solder-joint reliability under thermal cycling. Supplied on Tape & Reel (TR) for automated pick-and-place assembly.","metaTitle":"1N6343US/TR Zener Diode, 62 V, 500 mW, SQ-MELF, Tape & Reel","metaDescription":"Microchip Technology 1N6343US/TR Zener diode, 62 V ±5%, 500 mW, SQ-MELF B package, -65°C to 175°C.
