Overview
The EMZ6.8EFHT2R is a low capacitance Zener diode manufactured by ROHM Semiconductor, designed for ESD protection applications. It is qualified under the AEC-Q101 standard for automotive use. The device features a typical Zener voltage of 6.8V with a maximum rating of 7.14V and a minimum of 6.47V at a test current of 5mA. It operates within a junction temperature range of -55°C to +150°C and has a power dissipation rating of 150mW. The component is housed in an SOT-416 package (EMD3) with dimensions of 1.6x1.6mm and a thickness of 0.8mm, supplied in tape and reel packaging.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- Low capacitance design suitable for high-speed signal lines
- Compact surface-mount SOT-416 package for space-constrained layouts
Applications
- ESD protection for terminal protection devices
- Automotive electronic circuit protection
- High-speed data line transient suppression
Procurement Notes
Verify the specific ordering suffix and package code against the official datasheet before procurement. Confirm availability status as distribution listings may vary from manufacturer stock. Ensure the component meets the required AEC-Q101 qualification level for the intended application environment.
Selection Notes
Select this component when a low-capacitance Zener diode is required for ESD protection in automotive or high-speed digital circuits. The SOT-416 package offers a small footprint compared to larger TVS arrays. Verify that the 6.8V breakdown voltage aligns with the protected circuit's operating limits and that the 150mW power rating is sufficient for the expected transient energy.
Part Context
This part belongs to ROHM's series of Zener diodes specifically engineered for terminal protection devices. It serves as a compact solution for protecting sensitive inputs against electrostatic discharge events while maintaining signal integrity due to its low capacitance characteristics. The AEC-Q101 qualification ensures suitability for demanding automotive environments.
Replacement Considerations
The VDFH6.8B is listed as a similar specification part with a different package (SOD-723). Verify pinout compatibility and package dimensions before substitution. Other replacements require checking equivalent Zener voltage, capacitance, and AEC-Q101 compliance.
