EDZVFHT2R24B

Single Zener Diodes Overview

The EDZVFHT2R24B is a single Zener diode manufactured by ROHM Semiconductor, designed for surface-mount applications in the EMD2 (SOD-523) package. It features a nominal Zener voltage of 24 V with a tight tolerance of ±2%, ranging from 23.72 V to 24.78 V at a test current of 5 mA. The device supports a maximum power dissipation of 150 mW and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 100 nA and a Zener impedance of 120 Ohms. It holds AEC-Q101 qualification for automotive reliability.

Single Zener Diodes Feature Summary

• Ultra-small two-terminal plastic type with high-density mounting capability in the EMD2 package.
• Automotive-grade reliability certified under the AEC-Q101 standard.
• Low reverse leakage current ensures minimal power loss in standby states.
• Wide operating temperature range suitable for harsh automotive environments.

Single Zener Diodes Applications

• Voltage reference circuits in automotive electronic control units.
• Overvoltage protection for sensitive input pins in vehicle systems.
• Clamping applications in automotive infotainment and instrument clusters.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity, typically 8000 units per reel. Confirm that the EMD2 package dimensions align with your PCB footprint constraints. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the AEC-Q101 certification status if automotive qualification is mandatory for your design. Check for any recent lifecycle notices regarding obsolescence or last-time buy status.

Single Zener Diodes Selection Notes

Select this component when a precise 24 V reference is needed in space-constrained automotive designs. The EMD2 package offers a compact solution compared to larger SOD-123 variants. Consider the 120 Ohm Zener impedance for dynamic load regulation requirements. The 150 mW power rating must be sufficient for the expected surge currents in your application. Verify that the 5 mA test current aligns with your biasing network design.

Single Zener Diodes Part Context

This part belongs to the EDZVFHT2 series of small-signal Zener diodes from ROHM. The series is characterized by its ultra-miniature EMD2 package, which facilitates high-density mounting on printed circuit boards. These devices are specifically engineered to meet the rigorous demands of the automotive industry, offering robust performance across wide temperature ranges while maintaining low profile and weight.

Single Zener Diodes Replacement Considerations

The EDZ24B is listed as a recommended replacement with the same pinout and package. Both parts share identical Zener voltage specifications and power dissipation ratings. Verify that the legacy EDZ24B availability aligns with your production timeline before switching.
