CZRF52C2V7 Zener Diode Equivalent & Substitute Parts

Part Overview

The CZRF52C2V7 is a surface mount Zener diode manufactured by Comchip Technology, rated at 2.7 V nominal Zener voltage with 200 mW maximum power dissipation. The device is packaged in the 1005 (SOD-323F) form factor and is classified as Active product status. Substitute parts are identified when component availability is limited, supply chain disruptions occur, or inventory constraints require alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CZRF52C2V7 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Zener voltage: 2.7 V nominal
• Tolerance: ±5%
• Maximum power dissipation: 200 mW
• Impedance (Max): 83 Ohms
• Reverse leakage current: 75 µA @ 1 V
• Forward voltage: 900 mV @ 10 mA

Mechanical & Environmental Specifications:

• Package: 1005 (SOD-323F)
• Mounting: Surface Mount
• Operating temperature: -55°C to 125°C
• Moisture sensitivity: MSL 1

Compliance & Regulatory:

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99

The substitute part CZRF52C2V7-HF meets all electrical, mechanical, and compliance requirements and is therefore a direct parametric equivalent.
