Overview
The VMZ6.8NT2L is a low capacitance Zener diode manufactured by ROHM Semiconductor, designed for surface mount applications. It features a VMD3 package (SOT-723) with dimensions of 1.2x1.2 mm and a height of 0.55 mm. The device operates in an A-Common configuration with three terminals. Key electrical parameters include a nominal Zener voltage of 6.8V, with a minimum of 6.47V and a maximum of 7.14V at a test current of 5mA. Power dissipation is rated at 150mW, 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
- Compact SOT-723 surface mount package for space-constrained PCBs
- A-Common configuration providing versatile circuit integration
Applications
- ESD protection for high-speed data interfaces
- Voltage reference circuits in portable electronics
- Signal line protection in mobile devices
Procurement Notes
Verify the ordering part number VMZT6.8NT2L against the requested model VMZ6.8NT2L to ensure correct component identification. Confirm RoHS compliance and packaging type (taping) with the supplier. Check supply status as the related VMZT6.8N is listed as Last Time Buy, which may impact long-term availability for this specific reel quantity.
Selection Notes
Select this component when low capacitance is critical for maintaining signal integrity in high-frequency applications. Ensure the 150mW power rating and 6.8V Zener voltage align with the circuit's protection or regulation requirements. Verify that the SOT-723 footprint matches the PCB layout constraints.
Part Context
This component belongs to ROHM's low capacitance Zener diode series, optimized for protecting sensitive electronic components from electrostatic discharge. It serves as a compact alternative to larger packages while maintaining effective clamping performance for modern miniaturized devices.
Replacement Considerations
The CDZCV6.8B is documented as a recommended replacement with similar specifications. Note that the CDZCV6.8B uses a SOD-923 package (1.0x0.6 mm), requiring a different PCB footprint compared to the SOT-723 package of the VMZ6.8NT2L.
