CZRF52C36 Zener Diode Equivalent & Substitute Parts

Part Overview

The CZRF52C36 is a 36 V, 200 mW Zener diode manufactured by Comchip Technology in a surface mount 1005/SOD-323F package. This component is classified as an Active product and is ROHS3 compliant. Zener diodes of this specification are used in voltage regulation, overvoltage protection, and reference voltage circuits. Substitute parts may be required due to inventory constraints, supply chain disruptions, or design flexibility requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CZRF52C36 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Zener voltage: 36 V nominal
• Tolerance: ±5%
• Maximum power dissipation: 200 mW
• Maximum impedance: 90 Ohms
• Reverse leakage current: 100 nA @ 27 V
• Forward voltage: 900 mV maximum @ 10 mA
• Operating temperature range: -55°C to 125°C

Mechanical Parameters (Must Match):

• Package type: 1005/SOD-323F surface mount
• Mounting type: Surface mount

Compliance Parameters (Must Match):

• RoHS3 compliance
• Moisture Sensitivity Level 1

The substitute part CZRF52C36-HF meets all electrical, mechanical, and compliance requirements and is therefore a direct parametric equivalent.
