PDZVTR43A

Single Zener Diodes Overview

The PDZVTR43A is a single Zener diode manufactured by Rohm Semiconductor, designed for surface-mount applications. It features a PMDU (Small Power Mold Type) package, specifically SOD-128FL, with dimensions of 3.5x1.6 mm and a height of 0.95 mm. The device provides a nominal Zener voltage of 43 V, with a minimum of 40 V and a maximum of 46 V at a test current of 10 mA. It supports a power dissipation of 1000 mW and operates within a junction temperature range up to 150°C. The component is RoHS compliant and supplied in tape-and-reel packaging.

Single Zener Diodes Feature Summary

• High reliability construction utilizing the Small Power Mold Type (PMDU) package design
• Surface-mount compatibility with compact SOD-128FL footprint for space-constrained PCB layouts
• Stable voltage regulation capability suitable for reference voltage applications

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference voltages
• Electronic circuits needing precise Zener breakdown characteristics
• Surface-mount assembly for consumer or industrial electronics

Single Zener Diodes Procurement Notes

Verify the specific suffix 'A' against the official Rohm Semiconductor datasheet to confirm the exact voltage tolerance and binning. Ensure the ordering code matches the required tape-and-reel quantity. Confirm RoHS compliance status if restricted substance regulations apply to your manufacturing process. Cross-reference the package code SOD-128FL with your PCB footprint library to ensure mechanical fit.

Single Zener Diodes Selection Notes

Select this component when a 43 V Zener voltage is required in a small surface-mount form factor. The 1 W power rating allows for moderate current handling in regulated circuits. Consider the SOD-128FL package size constraints during layout. Verify that the operating temperature range meets the environmental requirements of the final application. Compare leakage current specifications if low-power standby modes are critical.
