MM3Z5V6ST1G Features
- 5.6 V nominal Zener voltage with ±2 percent tolerance provides a tight, predictable clamp/reference suitable for precision low‑power regulation.
- 300 mW power rating in a space‑saving SOD‑323 package enables effective protection and regulation where board area is limited.
- Low dynamic impedance (40 Ω at the specified test current) helps maintain a stable clamp voltage over varying load currents.
- Low forward voltage of approximately 0.9 V at 10 mA allows use in bidirectional or steering configurations when needed.
- Very low reverse leakage current (on the order of microamps at low reverse voltages) minimizes standby losses and preserves battery life in portable devices.
- Zener voltage near 5.6 V lies in the region where silicon Zeners typically exhibit a near‑zero temperature coefficient, contributing to improved voltage stability across operating temperatures.
- Ultra‑miniature SOD‑323 SC‑76 outline with low profile supports high‑density layouts and high‑speed automated assembly.
- Surface‑mount, tape‑and‑reel packaging supports efficient SMT manufacturing and automated optical inspection with clear cathode band polarity marking.
- Fully lead‑free with matte tin finish and compliant with modern lead‑free reflow profiles for straightforward process integration.
- Broad operating junction temperature range from −65 °C to +150 °C suits harsh and extended‑temperature applications.
