Substitute Part Grouping Explanation

Substitution of the DDZX27D-13 is determined by equivalence across the following critical parameters:

• Nominal Zener Voltage: 27 V (primary electrical specification)
• Maximum Power Dissipation: 300 mW (thermal rating)
• Package Type: SOT-23-3 (mechanical and thermal interface)
• Mounting Technology: Surface Mount (assembly compatibility)
• Operating Temperature Range: -65°C to 150°C (environmental specification)
• Impedance (Max): 45 Ohms (dynamic performance)
• Reverse Leakage Current: 50 nA @ 21 V (leakage specification)
• Forward Voltage: 900 mV @ 10 mA (forward conduction characteristic)

Substitute parts maintain identical values across all listed parameters. Tolerance variations are permitted when the substitute part tolerance is equal to or tighter than the main part specification.

Parameter Comparison

Engineering Selection Recommendations

The DDZX27D-7 is a direct parametric equivalent to the DDZX27D-13. Both components are manufactured by Diodes Incorporated and maintain Active product status.

Selection between these parts is based on tolerance requirements and inventory availability. The DDZX27D-7 is suitable for applications requiring tighter voltage tolerance control.

Frequently Asked Questions (FAQ)

Q: Can the DDZX27D-7 be used as a direct replacement for the DDZX27D-13?

A: Yes. The DDZX27D-7 is a direct parametric equivalent. All electrical specifications, power ratings, package type, and operating temperature ranges are identical. The substitute part features a tighter tolerance specification, which is compatible with applications designed for the main part.

Q: Are there any package or mounting differences between these parts?

A: No. Both the DDZX27D-13 and DDZX27D-7 use the SOT-23-3 package with surface mount technology. Footprint, lead spacing, and assembly requirements are identical.

Q: What is the significance of the tolerance difference?

A: The DDZX27D-7 has a ±2.5% tolerance compared to the ±3% tolerance of the DDZX27D-13. This means the DDZX27D-7 maintains a tighter voltage specification around the 27 V nominal value. For applications with strict voltage regulation requirements, the DDZX27D-7 provides improved accuracy.

Q: Are both parts compliant with current regulations?

A: Yes. Both the DDZX27D-13 and DDZX27D-7 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching the nominal Zener voltage (27 V), maximum power dissipation (300 mW), package type (SOT-23-3), operating temperature range (-65°C to 150°C), impedance (45 Ohms maximum), reverse leakage current (50 nA @ 21 V), and forward voltage characteristics (900 mV @ 10 mA). Tolerance specifications must be equal to or tighter than the original part.
