CZRUR52C13 Zener Diode 13V 150mW 0603 Equivalent & Substitute Parts

Part Overview

The CZRUR52C13 is a surface-mount Zener diode manufactured by Comchip Technology, rated at 13 V nominal Zener voltage with 150 mW maximum power dissipation in a 0603/SOD-523F package. This component is classified as Active product status and is ROHS3 compliant. Equivalent and substitute parts are identified based on matching electrical specifications and mechanical compatibility within the Zener diode category. Alternative part numbers may be required due to inventory availability, supply chain considerations, or design revision requirements while maintaining identical functional performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CZRUR52C13 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are defined by the following key parameters:

Electrical Specifications:

• Zener voltage: 13 V nominal
• Tolerance: ±5%
• Maximum power dissipation: 150 mW
• Impedance (Max): 25 Ohms
• Reverse leakage current: 100 nA @ 10 V
• Forward voltage: 900 mV @ 10 mA

Mechanical & Environmental Specifications:

• Package type: 2-SMD, No Lead (0603/SOD-523F)
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 125°C
• Moisture sensitivity: MSL 1 (Unlimited)
• Compliance: ROHS3 Compliant, REACH Unaffected

All substitute parts listed below match these parameters exactly and are manufactured by Comchip Technology. Substitution is valid for direct component replacement in circuit designs without modification to PCB layout or electrical design.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—CZRUR52C13, CZRU52C13, and CZRU52C13-HF—are functionally equivalent for circuit applications requiring a 13 V Zener diode with 150 mW power rating in 0603 surface-mount packaging. Selection among these alternatives is based on the following engineering considerations:

Product Status & Compliance: All parts maintain Active product status and are ROHS3 compliant with REACH Unaffected designation, meeting current regulatory requirements for electronic component procurement.

Inventory & Availability: CZRU52C13 offers the highest inventory level at 2210 pieces, followed by CZRUR52C13 at 1000 pieces, and CZRU52C13-HF at 671 pieces. Component selection may be influenced by supply chain requirements and lead-time considerations.

Electrical Performance: All three parts deliver identical electrical specifications across all measured parameters, including Zener voltage, power dissipation, impedance, leakage current, and forward voltage characteristics. No performance differentiation exists between the alternatives.

Mechanical Compatibility: All parts utilize identical 0603/SOD-523F surface-mount packaging with 2-SMD, No Lead configuration. Direct PCB footprint compatibility is confirmed across all substitute options without layout modification.

Frequently Asked Questions (FAQ)

Q: Can CZRU52C13 be used as a direct replacement for CZRUR52C13?

A: Yes. CZRU52C13 is a parametric equivalent with identical electrical specifications (13 V Zener voltage, 150 mW power rating, ±5% tolerance) and mechanical compatibility (0603/SOD-523F package, surface mount). Direct substitution is valid without circuit modification.

Q: What is the difference between CZRU52C13 and CZRU52C13-HF?

A: Both parts are parametric equivalents with matching electrical and mechanical specifications. The "-HF" suffix indicates a variant designation from Comchip Technology but does not reflect differences in the provided electrical parameters. Both are suitable for identical applications.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All three parts use the 0603/SOD-523F surface-mount package with 2-SMD, No Lead configuration. PCB footprint compatibility is confirmed without layout modification required.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is identical across all alternatives.

Q: Which part should be selected based on availability?

A: CZRU52C13 provides the highest inventory level (2210 pieces). CZRUR52C13 (1000 pieces) and CZRU52C13-HF (671 pieces) are secondary options. Selection should align with supply chain and procurement timelines.

Q: Are there any temperature or operating condition differences between the substitutes?

A: No. All parts operate across the identical temperature range of -55°C to 125°C with matching thermal and electrical performance characteristics.
