PDZVTR10B

Single Zener Diodes Overview

The PDZVTR10B is a unidirectional silicon Zener diode manufactured by ROHM Semiconductor, designed for constant voltage control applications. It features a PMDTM (SOD-128) surface-mount package with dimensions of 4.7x2.5 mm and a thickness of 1.05 mm. The device operates with a maximum power dissipation of 1 W and maintains a junction temperature up to 150 °C. Key electrical specifications include a Zener voltage range from 10 V minimum to 11.2 V maximum, measured at a test current of 40 mA. The component supports an operating temperature range from -55 °C to 150 °C and complies with RoHS standards.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status matches current regulatory requirements. Ensure the selected distributor provides official datasheets to validate the 1W power rating and SOD-128 package dimensions. Check for any automotive restrictions as standard grade products may not be recommended for vehicle equipment.

Single Zener Diodes Selection Notes

Select this component for designs requiring a 10V Zener reference in a compact surface-mount footprint. The 1W power dissipation allows for higher current handling compared to smaller packages. Verify that the 40mA test current aligns with the circuit's biasing requirements. Consider the 150°C junction temperature limit for thermal management in enclosed spaces.

Single Zener Diodes Part Context

This part belongs to ROHM's PDZV series of small plastic Zener diodes. The series emphasizes high reliability and compact sizing for modern electronics. The PMDTM package offers a balance between power handling and board space efficiency. This specific model represents a standard-grade device intended for general industrial and consumer applications rather than specialized automotive use.
