Overview
The UMZ5.1NT106 is a low capacitance Zener diode manufactured by Rohm Semiconductor, designed for terminal protection applications. It operates within an AEC-Q101 qualified automotive grade standard, ensuring reliability in demanding environments. The device features a typical Zener voltage of 5.1V with a maximum power dissipation of 200mW. It utilizes a UMD3 (SOT-323) surface-mount package, measuring 2.1x2.0mm with a thickness of 1.0mm. The component supports a junction temperature up to 150°C and a storage temperature range from -55°C to 150°C. Testing is conducted at a current of 5mA.
Feature Summary
- AEC-Q101 qualified for automotive reliability
- Low capacitance design for signal integrity
- Compact UMD3 surface-mount packaging
Applications
- Terminal protection devices
- Automotive electronic circuits
- ESD protection for high-speed interfaces
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct tape-and-reel configuration and compliance with RoHS standards. Confirm that the selected variant matches the required automotive qualification level and package dimensions before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring robust ESD protection with minimal impact on signal lines. Ensure the operating voltage remains below the breakdown threshold and that the power dissipation limits are respected under worst-case thermal conditions to maintain long-term device stability.
Part Context
This part belongs to Rohm's UMZ series of low capacitance Zener diodes. The series is engineered specifically for protecting sensitive input/output terminals in automotive and industrial systems. These devices offer a balance of compact size and high transient voltage suppression capability.
Replacement Considerations
Check for direct pin-compatible alternatives such as the UMZU6.2N or UMZ18NFH if voltage requirements differ. Verify that any substitute maintains the same UMD3 package footprint and meets AEC-Q101 standards for automotive integration.
