The document describes the features and characteristics of 0.5 watt glass surface mount DO-213AA Zener voltage regulators in the 1N4099UR to 1N4135UR and 1N4614UR to 1N4627UR series. These regulators offer a selection of 1.8 to 100 volts with standard 5% tolerances and tighter tolerances identified by different suffix letters. They are also available with an internal-metallurgical-bond option, including JAN, JANTX, and JANTXV military qualifications. Microsemi also offers other Zener products for higher and lower power applications.
The 1N4099UR‑1N4135UR and 1N4614UR‑1N4627UR series are 0.5 W glass surface‑mount Zener voltage regulators in a DO‑213AA (SOD80) MELF style package. They provide a selection from 1.8 V to 100 V with standard ±5 % tolerances and tighter ±2 % or ±1 % options using C or D suffixes.
Key specifications include a steady‑state power dissipation of 0.5 W, operating temperature range of 65 °C to +175 °C, thermal resistance of 150 °C·W⁻¹ junction‑to‑end‑cap, forward voltage of 1.1 V at 200 mA, and a soldering temperature limit of 260 °C for 10 s. The hermetically sealed glass case weighs 0.04 g and is available on tape‑and‑reel.
