Overview
The UMZ8.2TT106 is a low capacitance Zener diode manufactured by ROHM Semiconductor, designed for transient voltage suppression and circuit protection applications. It features a UMD3 (SOT-323) surface-mount package with dimensions of 2.1x2.0 mm. The device has a typical Zener voltage of 8.2V, with a minimum of 7.84V and a maximum of 8.59V at a test current of 5mA. It supports a power dissipation of 200mW and operates within a junction temperature range up to 150°C. Storage temperatures range from -55°C to 150°C. The component is RoHS compliant and supplied in tape-and-reel packaging.
Feature Summary
- Low capacitance design suitable for high-speed signal line protection
- Compact SOT-323 surface-mount package for space-constrained designs
- High reliability Zener breakdown characteristics for stable voltage regulation
Applications
- ESD protection for data lines in portable electronics
- Voltage reference circuits requiring compact form factors
- Transient voltage suppression in consumer automotive interfaces
Procurement Notes
Verify the specific ordering suffix against official ROHM documentation to ensure correct packaging and reel specifications. Confirm supply status as legacy or recommended for new designs prior to procurement. Ensure compatibility with existing PCB footprints designated for UMD3 packages during integration planning.
Selection Notes
Select this component when low parasitic capacitance is critical for maintaining signal integrity in protected lines. Verify that the 200mW power dissipation rating meets the thermal requirements of the target application environment. Ensure the Zener voltage tolerance aligns with the circuit's protection thresholds.
Part Context
This part belongs to ROHM's UMZ series of low capacitance Zener diodes, which are optimized for protecting sensitive electronic components from electrostatic discharge and other transient overvoltage events. The series is widely used in mobile devices and industrial equipment where small footprint and fast response times are required.
Replacement Considerations
Check for direct pin-compatible alternatives such as the UMZ8.2NFM if the TT106 suffix indicates a specific packaging variant no longer supported. Verify electrical parameter equivalence before substitution.
