CZRQC52C33A-HF

Single Zener Diodes Overview

The CZRQC52C33A-HF is a Zener diode manufactured by Comchip Technology, designed for surface-mount applications. It features a nominal Zener voltage of 33 V with a tight tolerance of 2.5%. The device operates within a power dissipation limit of 125 mW and utilizes the SOD-923F-2 package. Key electrical parameters include a maximum reverse leakage current of 100 nA and a Zener impedance of 40 Ohms at a test current of 5 mA. The component supports an operating temperature range from -55 °C to +125 °C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a 2.5% tolerance on the 33 V Zener voltage.
• Utilizes a low-profile SOD-923F-2 package suitable for automated assembly processes.
• Ensures stable operation across a wide industrial temperature range up to 125 °C.

Single Zener Diodes Applications

• Voltage reference circuits requiring high precision.
• Protection against overvoltage transients in sensitive electronics.
• Clamping applications in signal processing paths.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'HF' indicates halogen-free compliance as per manufacturer documentation. Confirm the exact package dimensions and pinout configuration against the official datasheet before PCB layout finalization. Ensure thermal management strategies align with the 125 mW power dissipation rating under expected operating conditions.

Single Zener Diodes Selection Notes

Select this component when a 33 V reference with tighter than standard 5% tolerance is required. The SOD-923F-2 package offers space savings compared to larger SMD packages. Consider the 100 nA leakage current specification for low-power circuit designs where minimal standby drain is critical.

Single Zener Diodes Part Context

This part belongs to the CZRQC series of Zener diodes from Comchip Technology. The series is characterized by planar die construction and halogen-free materials. It serves as a compact solution for voltage regulation tasks in consumer and industrial electronic devices requiring reliable performance in small form factors.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 33 V Zener voltage, 2.5% tolerance, 125 mW power rating, and SOD-923F-2 package. Verify equivalent electrical characteristics such as Zener impedance and leakage current to ensure circuit compatibility without redesign.
