CZRER52C11

Single Zener Diodes Overview

The Comchip Technology CZRER52C11 is a single surface-mount Zener diode housed in the 0503 (1308 metric) package. It provides a nominal Zener voltage of 11 V with a tolerance of ±5%. The device supports a maximum power dissipation of 150 mW at 25°C and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a maximum forward voltage drop of 0.9 V at 10 mA, a peak ESD voltage capability compliant with IEC 61000-4-2 standards, and gold-plated terminals solderable per MIL-STD-750 method 2026.

Single Zener Diodes Feature Summary

• Halogen-free construction utilizing planar die technology for enhanced reliability
• Extremely thin, leadless 0503 package designed for compact surface mounting
• High voltage operation capability ranging from 2 V to 39 V across the series
• Robust electrostatic discharge protection meeting IEC 61000-4-2 standards

Single Zener Diodes Applications

• Voltage regulation in low-power surface-mounted circuits
• Protection against electrostatic discharge in sensitive electronic components
• Reference voltage generation in compact consumer electronics

Single Zener Diodes Procurement Notes

Verify the specific suffix designation when ordering, as variations such as -HF indicate halogen-free compliance. Confirm that the required voltage rating aligns precisely with the circuit design needs, as the 0503 package limits thermal dissipation capabilities compared to larger packages. Ensure compatibility with automated assembly processes due to the small form factor and leadless design specifications provided by the manufacturer.

Single Zener Diodes Selection Notes

Select this component for applications requiring precise voltage clamping in space-constrained designs where standard through-hole packages are unsuitable. The 150 mW power rating defines the maximum current handling capacity under steady-state conditions. Consider the operating temperature range and ESD robustness when deploying in environments subject to mechanical stress or high static electricity exposure.

Single Zener Diodes Part Context

This component belongs to the CZRER52C series of single Zener diodes manufactured by Comchip Technology. The series offers a wide range of voltage options from 2 V to 39 V, all sharing the same compact 0503 footprint. This standardization allows designers to maintain consistent board layouts while adjusting voltage requirements across different product variants within the same family.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 11 V Zener voltage, 150 mW power dissipation, and 0503 package dimensions. Verify that alternative manufacturers offer comparable ESD protection levels and forward voltage characteristics to ensure circuit performance parity.
