HZK7CTR-S-E

Single Zener Diodes Overview

The HZK7CTR-S-E is a single Zener diode manufactured by Renesas Electronics Corporation, designed for surface-mount applications. It features a nominal Zener voltage of 7 V with a tolerance of ±5% and a maximum power dissipation of 500 mW. The device utilizes an LLD (DO-213AC, MINI-MELF, SOD-80) package and supports a maximum operating junction temperature of 175°C. Key electrical characteristics include a maximum Zener impedance of 15 Ohms and a reverse leakage current of 1 µA at 3.5 V.

Single Zener Diodes Feature Summary

• Surface-mount construction in an LLD package for automated assembly
• High thermal stability supporting operation up to 175°C junction temperature
• Tight voltage tolerance of ±5% for precise regulation
• Low reverse leakage current for efficient standby performance

Single Zener Diodes Applications

• Voltage reference circuits requiring stable 7 V levels
• Overvoltage protection in low-power electronic systems
• Clamping applications in signal conditioning paths

Single Zener Diodes Procurement Notes

Verify the specific suffix 'S-E' against official Renesas documentation to confirm compliance status and packaging details, as standard listings may vary. Confirm RoHS compliance requirements explicitly, as some variants are marked non-compliant. Ensure the ordering part number matches the exact tape-and-reel or bulk specifications required for your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Single Zener Diodes Selection Notes

Select this component when a compact surface-mount Zener diode with high-temperature capability is required. The LLD package offers space efficiency compared to axial leads. Consider the 500 mW power rating for thermal management in dense PCB layouts. Verify that the 7 V breakdown voltage aligns with the circuit's clamping or reference needs without exceeding the maximum allowable reverse voltage.

Single Zener Diodes Part Context

The HZK7CTR series belongs to Renesas' lineup of small-signal Zener diodes optimized for surface-mount technology. These devices are engineered for reliability in consumer and industrial electronics where space constraints and thermal performance are critical. The LLD package variant provides a robust mechanical solution for high-volume production environments.

Single Zener Diodes Replacement Considerations

Consult official substitution guides for equivalent LLD-packaged Zener diodes with matching 7 V and 500 mW ratings. Verify pinout compatibility and thermal resistance parameters before replacing.
