MM5Z5V1 Zener Diode Equivalent & Substitute Parts
Part Overview
The MM5Z5V1 is an active-status zener diode manufactured by Diotec Semiconductor, designed for voltage regulation and protection applications. This surface-mount component operates at a nominal zener voltage of 5.1 V with a maximum power dissipation of 200 mW. The part is packaged in SOD-523 (SC-79) format and is ROHS3 compliant. Equivalent and substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across different manufacturers, enabling procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation
Substitution of the MM5Z5V1 is determined by strict equivalence across the following critical parameters:
- Zener Voltage (Nominal): 5.1 V
- Voltage Tolerance: ±5%
- Maximum Power Dissipation: 200 mW
- Maximum Impedance: 60 Ohms
- Reverse Leakage Current: 2 µA specification
- Operating Temperature Range: -65°C to 150°C
- Package Format: SOD-523 surface-mount configuration
- Regulatory Compliance: ROHS3 Compliant, REACH Unaffected
The BZT52C5V1K RKG manufactured by Taiwan Semiconductor Corporation meets all specified electrical and mechanical parameters, enabling direct substitution in applications requiring 5.1 V zener regulation at 200 mW power levels.

Engineering Selection Recommendations
Both the MM5Z5V1 and BZT52C5V1K RKG are active-status components with full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Selection between these parts is based on availability, packaging format preference, and supply chain requirements rather than electrical performance differentiation.
The MM5Z5V1 is supplied in Cut Tape (CT) and Digi-Reel® packaging with 27,620 units in stock. The BZT52C5V1K RKG is supplied in Tape & Reel (TR) format with 7,102 units in stock. Both components are suitable for production environments requiring surface-mount zener diodes with 5.1 V regulation capability at 200 mW power dissipation.
Frequently Asked Questions (FAQ)
Q: Can the BZT52C5V1K RKG replace the MM5Z5V1 in existing designs?
A: Yes. Both components share identical zener voltage (5.1 V), tolerance (±5%), maximum power (200 mW), impedance (60 Ohms), operating temperature range (-65°C to 150°C), and SOD-523 package format. Electrical performance and mechanical compatibility are equivalent.
Q: What is the difference in reverse leakage current specifications?
A: The MM5Z5V1 specifies 2 µA reverse leakage at 2 V, while the BZT52C5V1K RKG specifies 2 µA at 1.5 V. Both meet the 2 µA leakage requirement; the measurement voltage differs but does not affect substitution eligibility.
Q: Are there packaging differences between these parts?
A: The MM5Z5V1 is available in Cut Tape (CT) and Digi-Reel® formats. The BZT52C5V1K RKG is supplied in Tape & Reel (TR) format. Both use the SOD-523 package. Selection depends on assembly line equipment compatibility and procurement volume requirements.
Q: Do both parts meet current regulatory standards?
A: Yes. Both the MM5Z5V1 and BZT52C5V1K RKG are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component use.
Q: What is the moisture sensitivity level for these components?
A: The MM5Z5V1 has no applicable moisture sensitivity level (MSL). The BZT52C5V1K RKG is rated MSL 1 (Unlimited), indicating minimal moisture sensitivity and standard handling requirements.
