PDZVTFTR6.8B

Single Zener Diodes Overview

The PDZVTFTR6.8B is a single Zener diode manufactured by ROHM Semiconductor, designed for surface-mount applications in the SOD-128 package. It features a nominal Zener voltage range of 6.8 V to 7.7 V with a maximum power dissipation of 1 W. The device operates at a test current of 40 mA and maintains a low Zener impedance of 4 Ohms. It supports a maximum junction temperature of 150°C and is supplied in tape-and-reel packaging.

Single Zener Diodes Feature Summary

• High power dissipation capability of 1 W within a compact SOD-128 footprint
• Low Zener impedance of 4 Ohms for stable voltage regulation
• Extended thermal performance supporting a maximum junction temperature of 150°C

Single Zener Diodes Applications

• Voltage reference circuits requiring high power handling
• Over-voltage protection stages in industrial electronics
• Clamping applications in automotive-grade systems

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix and package variant against the official datasheet to ensure compatibility with your PCB layout. Confirm that the 1 W power rating aligns with your thermal design constraints. Check for RoHS compliance status and lead time requirements directly with authorized distributors before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a standard Zener diode requires higher power dissipation than typical SOD-123 packages allow. The 1 W rating in the SOD-128 form factor provides a robust solution for space-constrained designs needing precise voltage clamping. Ensure the 6.8 V to 7.7 V tolerance range meets your circuit's regulatory specifications.

Single Zener Diodes Part Context

This part belongs to ROHM's PMDTM series of Zener diodes, which are engineered for high-power density in small surface-mount packages. The series targets applications demanding reliable voltage regulation under significant thermal stress, offering an alternative to larger through-hole or standard SMD diodes.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1 W Zener diodes in the SOD-128 package with similar voltage ranges. Verify pinout compatibility and thermal resistance characteristics when replacing with components from other manufacturers.
