BZX584B12HE3-TP

Single Zener Diodes Overview

The BZX584B12HE3-TP is a 12 V nominal Zener diode with ±2% tolerance, housed in an SOD-523 surface-mount package. It dissipates up to 150 mW and operates within a junction temperature range of -55°C to +150°C. Key electrical parameters include a maximum dynamic impedance (ZZT) of 25 Ω at IZT = 5 mA, a forward voltage of 0.9 V at IF = 10 mA, and a reverse leakage current of 100 nA maximum at VR = 8 V.

Single Zener Diodes Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• Halogen-free 'Green' device compliant with environmental directives
• Planar die construction designed for automated assembly processes

Single Zener Diodes Applications

Single Zener Diodes Procurement Notes

Verify the component against official Micro Commercial Components datasheets to confirm exact electrical tolerances and thermal characteristics. Ensure sourcing from authorized distributors to guarantee genuine parts with full traceability. Confirm RoHS compliance and packaging specifications match project requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component for designs requiring precise voltage regulation in compact surface-mount layouts. The SOD-523 package suits high-density PCBs, while the AEC-Q101 qualification supports automotive integration. Evaluate thermal derating curves for operation above ambient temperatures to ensure power dissipation limits are not exceeded.

Single Zener Diodes Part Context

This part belongs to the BZX584B series of low-power Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 3.6 V to 36 V, all sharing the same SOD-523 footprint and general electrical profile. The 'HE3' suffix indicates Halogen-free Epoxy, and 'TP' denotes Tape & Reel packaging.

Single Zener Diodes Replacement Considerations

Cross-reference with other BZX584B12 variants from different manufacturers if pinout compatibility is required. Verify that substitute components meet the same ±2% tolerance and 150 mW power dissipation ratings.
