• Power Dissipation: 300 mW maximum
• Impedance (Zzt): 20 Ohms maximum
• Configuration: 1 Pair Common Cathode
• Package Type: SOT-23 / SOT-23-3 surface mount
• Compliance: ROHS3 compliant, REACH unaffected
• Moisture Sensitivity: MSL 1 (Unlimited)

The substitute part DZ23C12-7-F from Diodes Incorporated meets all specified electrical and mechanical parameters, enabling direct functional replacement in circuit applications where the DZ23C12-TP is designated.

Parameter Comparison

Engineering Selection Recommendations

Both the DZ23C12-TP and DZ23C12-7-F are active products with identical electrical specifications and package configurations. Selection between these components is based on the following factors:

Availability and Supply Chain: The DZ23C12-7-F from Diodes Incorporated currently maintains higher inventory levels (28,901 pcs) compared to the DZ23C12-TP (3,580 pcs), providing greater supply assurance for high-volume production requirements.

Compliance and Certification: Both parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for commercial and industrial applications.

Operating Temperature Range: The DZ23C12-7-F specifies an operating temperature range of -65°C to 150°C. The DZ23C12-TP does not provide explicit operating temperature specifications in available documentation.

Functional Equivalence: The parts are electrically and mechanically interchangeable for all specified parameters, including Zener voltage, power rating, impedance, and package type.

Frequently Asked Questions (FAQ)

Q: Can the DZ23C12-7-F directly replace the DZ23C12-TP in existing circuit designs?

A: Yes. Both components share identical electrical specifications (12 V Zener voltage, 300 mW power rating, 20 Ohms impedance, ±5% tolerance) and package configuration (SOT-23-3 surface mount). No circuit modifications are required for substitution.

Q: Are there differences in the physical package dimensions between these parts?

A: Both parts use the SOT-23-3 package type, which is standardized as TO-236-3 and SC-59. Physical dimensions and pin configurations are identical, enabling direct PCB footprint compatibility.

Q: What is the significance of the "1 Pair Common Cathode" configuration?

A: This configuration indicates the Zener diode array contains two diodes with a shared cathode connection. This internal arrangement must be matched in any substitute component to ensure correct circuit operation and pin compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DZ23C12-TP and DZ23C12-7-F are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements for commercial applications.

Q: What is the Moisture Sensitivity Level (MSL) rating, and why is it important?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly processes.

Q: How do the impedance specifications affect circuit performance?

A: The maximum impedance (Zzt) of 20 Ohms is identical for both parts. This parameter defines the dynamic resistance of the Zener diode and directly influences voltage regulation stability and transient response characteristics in protection circuits.
