Key Parameters

Substitute Part Grouping Explanation

Substitution of the DDZX14-13 is determined by strict equivalence across the following critical parameters:

• Zener Voltage (Vz): 14 V nominal with ±3% tolerance
• Power Rating: 300 mW maximum dissipation
• Package Type: SOT-23-3 surface mount configuration
• Impedance (Zzt): 16 Ohms maximum
• Reverse Leakage Current: 50 nA @ 11 V
• Forward Voltage: 900 mV maximum @ 10 mA
• Operating Temperature Range: -65°C to 150°C
• Compliance: ROHS3 Compliant, REACH Unaffected

The DDZX14-7 is a parametric equivalent manufactured by Diodes Incorporated. Both parts share identical electrical specifications and package designation, differing only in packaging format (tape & reel variant designation). The DDZX14-7 maintains full compatibility with circuits designed for the DDZX14-13.

Parameter Comparison

Engineering Selection Recommendations

Both the DDZX14-13 and DDZX14-7 are active products from Diodes Incorporated with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than technical performance differences.

The DDZX14-13 is suitable for applications requiring immediate availability, with 830 pieces in current stock. The DDZX14-7 offers higher inventory levels at 2104 pieces, providing supply chain flexibility for high-volume production or extended lead time mitigation.

Both parts maintain full ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for commercial and industrial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can DDZX14-7 be used as a direct replacement for DDZX14-13?

A: Yes. Both parts are parametric equivalents with identical Zener voltage (14 V), power rating (300 mW), impedance (16 Ohms), and SOT-23-3 package configuration. No circuit modifications are required.

Q: What is the difference between DDZX14-13 and DDZX14-7?

A: The parts are electrically and mechanically identical. The designation difference reflects packaging format variants within the same product line. Both are supplied in tape & reel format.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited). Regulatory and environmental requirements are equivalent.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. Selection should be based on current inventory availability and supply chain lead times. Both maintain active product status with Diodes Incorporated.

Q: Is the SOT-23-3 package compatible with existing PCB layouts?

A: Yes. Both DDZX14-13 and DDZX14-7 use the SOT-23-3 package designation (also referenced as TO-236-3 or SC-59). PCB footprints and assembly processes remain unchanged.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -65°C to 150°C, supporting industrial and extended temperature applications without derating.
