Overview
The UMZ16NT106 is a Zener diode manufactured by ROHM Semiconductor, designed for surface-mount applications in the SOT-323 (UMD3) package. It features a nominal Zener voltage of 16 V with a tight tolerance of ±2%. The device operates with a test current of 5 mA and exhibits a maximum reverse leakage current of 100 nA at the rated voltage. It has a power dissipation rating of 200 mW and a Zener impedance of 50 Ohms. The component supports an operating temperature range from -55°C to +150°C and is qualified under the AEC-Q101 standard for automotive reliability.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q101 standards for enhanced reliability in vehicle electronics.
- Compact UMD3 (SOT-323) plastic package design suitable for space-constrained surface-mount layouts.
- Low leakage current characteristics ensuring stable performance in precision voltage regulation circuits.
Applications
- Terminal protection devices requiring transient voltage suppression.
- Voltage reference circuits in automotive electronic control units.
- General-purpose voltage regulation in compact consumer electronics.
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm packaging type and tape-and-reel specifications. Ensure the procurement channel sources genuine ROHM Semiconductor components to maintain AEC-Q101 compliance. Cross-reference the part number with authorized distributors to avoid counterfeit products that may lack proper traceability or quality certification documentation.
Selection Notes
Select this component when a precise 16 V reference is required in a small form factor. The low leakage current makes it suitable for high-impedance circuits. Confirm that the 200 mW power dissipation meets the thermal requirements of the target application. Verify compatibility with the SOT-323 footprint during PCB layout design to ensure proper soldering and mechanical stability.
Part Context
This part belongs to the UMZ series of Zener diodes from ROHM Semiconductor, which are optimized for terminal protection and voltage regulation. The series includes various voltage ratings within the same UMD3 package, allowing for standardized inventory management across different circuit designs. The UMZ16 variant specifically targets applications needing a 16 V breakdown voltage with high accuracy.
Replacement Considerations
Direct substitutes must match the 16 V Zener voltage, SOT-323 package, and 200 mW power rating. Check for equivalent AEC-Q101 qualification if automotive use is intended. Verify pinout compatibility and electrical parameters such as leakage current and impedance before substitution.
