Overview
The FTZ6.8ET148 is a Zener diode array manufactured by ROHM Semiconductor, designed for terminal protection applications. It features a quad-chip configuration with an anode-common arrangement housed in an SOT-25T (SC-74A) surface-mount package. The device provides a typical Zener voltage of 6.8 V at a test current of 5 mA, with a maximum power dissipation of 200 mW. It supports a junction temperature range from -55°C to +150°C and complies with IEC61000-4-2 standards, offering specific capacitance and resistance values for ESD protection.
Feature Summary
- Integrated quad-chip Zener array structure for compact circuit design
- Anode-common configuration simplifies wiring in protection circuits
- Compliant with IEC61000-4-2 electrostatic discharge standards
Applications
- Terminal protection devices requiring ESD mitigation
- I/O port protection in electronic systems
- Surge suppression circuits adhering to IEC61000-4-2 guidelines
Procurement Notes
Verify the exact ordering suffix and tape quantity against the official ROHM datasheet before purchase. Confirm that the SOT-25T package dimensions match your PCB footprint requirements. Ensure the component meets the necessary RoHS compliance standards for your target market regulations.
Selection Notes
Select this component when a multi-channel Zener solution is needed for common-anode protection schemes. Compare the 200 mW power rating and 6.8 V breakdown voltage against system requirements. Verify that the IEC61000-4-2 performance metrics align with your product's safety certification goals.
Part Context
This part belongs to ROHM's line of Zener arrays specifically engineered for terminal protection. It complements other discrete Zener diodes by offering integrated multi-channel functionality in a small surface-mount form factor, reducing board space and assembly complexity for protection circuits.
Replacement Considerations
Consult the official ROHM datasheet for the FTZ series to identify direct replacements or similar specifications. Verify package compatibility and electrical parameters such as Zener voltage tolerance and power dissipation before substituting.
