KDZTR12B

Single Zener Diodes Overview

The KDZTR12B is a Zener diode manufactured by Rohm Semiconductor, designed for voltage regulation applications. It features a PMDU package with SOD-123FL footprint and SC-109B JEITA classification. The device operates with a typical Zener voltage of 12.5V, ranging from 12.0V to 13.5V at a test current of 20mA. It supports a maximum power dissipation of 1000mW and a junction temperature up to 150°C. Storage temperatures range from -55°C to 150°C. The component is supplied in taping format with a unit quantity of 3000.

Single Zener Diodes Procurement Notes

Verify the specific ordering part number KDZTR12B against official Rohm documentation to ensure correct configuration. Confirm that the PMDU package and SOD-123FL footprint match your PCB layout requirements. Check the supply status as this product may be designated for existing customers only and not recommended for new designs. Ensure compliance with RoHS standards if required for your application environment.

Single Zener Diodes Selection Notes

Select this component when a 12V nominal Zener voltage with high power handling is required in a compact surface mount package. Compare electrical characteristics such as Zener impedance and test current against circuit requirements. Consider the replacement option KDZV12B if new design support is necessary, as it shares the same pinout and package while being recommended for new designs.

Single Zener Diodes Part Context

The KDZTR12B belongs to Rohm's Zener diode family, specifically utilizing the PMDU package type. It is functionally similar to the KDZV12B but differs in supply status recommendations. This component is part of Rohm's portfolio of small signal diodes designed for general-purpose voltage regulation tasks in consumer and industrial electronics.

Single Zener Diodes Replacement Considerations

The KDZV12B is a confirmed substitute with the same pinout and package. It is recommended for new designs whereas the KDZTR12B is not.
