Overview
The ROHM Semiconductor EMZ6.8NTL is a dual common anode Zener diode array housed in a compact SOT-353 (SC-85) surface-mount package. It features a nominal Zener voltage of 6.8 V with a maximum reverse leakage current of 500 nA and a Zener impedance of 40 Ohms at a test current of 5 mA. The device supports a power dissipation of 200 mW and operates within a junction temperature range up to +150°C. Designed for high-density mounting, it provides stable voltage regulation in small form factors suitable for portable electronics.
Feature Summary
- Dual common anode configuration enables efficient space-saving layout for multi-channel protection or reference applications.
- Compact SOT-353 package design facilitates high-density surface mount assembly on printed circuit boards.
- Low leakage current characteristics support precise voltage regulation in sensitive signal paths.
Applications
- Voltage reference circuits requiring stable DC levels.
- Input protection stages in data lines and communication interfaces.
- Clamping applications in portable consumer electronic devices.
Procurement Notes
Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and tape specifications. Confirm RoHS compliance status and automotive qualification requirements if applicable to the target application environment before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener configuration is required in a minimal footprint. Ensure the 200 mW power dissipation rating aligns with the thermal management capabilities of the host system. Verify that the 6.8 V breakdown voltage meets the circuit's clamping or reference thresholds under expected operating currents.
Part Context
This part belongs to ROHM's UMZ series of low-capacitance Zener diodes designed for ESD protection and voltage regulation. The series emphasizes miniaturization and reliability for modern mobile and IoT devices. The EMZ6.8NTL variant specifically utilizes the SOT-353 package to balance performance with board space constraints.
Replacement Considerations
Consider the UMZ6.8ENTR as a direct functional substitute within the same series. Verify pin compatibility and package dimensions before substitution. Alternative packages such as SOD-323 may require schematic redesign due to different pinout configurations.
