Overview
The UMZ8.2NT106 is a low capacitance Zener diode manufactured by Rohm Semiconductor, designed for voltage regulation and transient protection in surface-mount applications. It utilizes the UMD3 (SOT-323) package with dimensions of 2.1x2.0 mm and a thickness of 1.0 mm. The device features an A-common configuration with three terminals. Key electrical parameters include a typical Zener voltage of 8.2 V, with a minimum of 7.84 V and a maximum of 8.59 V at a test current of 5 mA. Power dissipation is rated at 200 mW, with a maximum junction temperature of 150 °C and a storage temperature range from -55 °C to 150 °C.
Feature Summary
- Low capacitance design suitable for high-speed signal lines
- AEC-Q101 qualified for automotive reliability standards
- Compact SOT-323 surface mount package
Applications
- I/O port protection in mobile devices
- ESD protection for data lines
- Voltage reference circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct tape-and-reel quantity and packaging type. Confirm RoHS compliance status and check for any 'Not Recommended for New Designs' notices that may affect long-term availability or production support status before finalizing procurement plans.
Selection Notes
Select this component when a precise 8.2 V Zener voltage is required in a minimal footprint. Ensure the circuit operates within the 200 mW power dissipation limit and that the low capacitance characteristic aligns with the signal integrity requirements of the application. Verify thermal management capabilities for the intended operating environment.
Part Context
This part belongs to Rohm's UMZ series of low capacitance Zener diodes, which are optimized for ESD protection and voltage clamping in portable electronics. The series offers various voltage options within the same SOT-323 package family, allowing for standardized PCB layouts across different product designs requiring similar form factors and protection levels.
Replacement Considerations
Check for direct pin-compatible alternatives such as the UMZ8.2NFM if different packing quantities are needed. Verify that substitute parts maintain the same Zener voltage tolerance, capacitance values, and AEC-Q101 qualification if automotive use is intended.
