Key Parameters

Substitute Part Grouping Explanation

Substitution of the DDZX15-13 is determined by strict equivalence across the following critical parameters:

• Zener Voltage (Vz): 15 V nominal with ±3% tolerance
• Power Rating: 300 mW maximum dissipation
• Package Type: SOT-23-3 surface mount configuration
• Impedance (Zzt): 18 Ohms maximum
• Reverse Leakage Current: 50 nA @ 12 V
• Forward Voltage: 900 mV maximum @ 10 mA
• Operating Temperature Range: -65°C to 150°C
• Compliance: RoHS3 compliant, MSL 1 rating

The DDZX15-7 is identified as a parametric equivalent substitute. Both parts share identical electrical specifications and mechanical packaging, differing only in packaging format (tape & reel designation). The substitute maintains full compatibility with circuit designs specified for the DDZX15-13.

Parameter Comparison

Engineering Selection Recommendations

Both the DDZX15-13 and DDZX15-7 are active products from Diodes Incorporated with identical electrical and mechanical specifications. Selection between these parts is based on availability and packaging format requirements:

• DDZX15-13: 816 pieces in stock. Use when tape & reel packaging format designated as DDZX15-13 is specified in procurement documentation.
• DDZX15-7: 4200 pieces in stock. Use when tape & reel packaging format designated as DDZX15-7 is specified, or when higher inventory availability is required.

Both parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for commercial and industrial applications. The unlimited moisture sensitivity rating (MSL 1) permits standard handling and storage without special environmental controls. No additional testing or qualification is required when substituting between these parts, as all critical parameters are identical.

Frequently Asked Questions (FAQ)

Q: Can DDZX15-7 be used as a direct replacement for DDZX15-13 in existing circuit designs?

A: Yes. The DDZX15-7 is electrically and mechanically identical to the DDZX15-13. All electrical parameters, including zener voltage, power rating, impedance, leakage current, and forward voltage, are equivalent. The SOT-23-3 package footprint is identical, permitting direct PCB substitution without design modification.

Q: What is the difference between DDZX15-13 and DDZX15-7?

A: Both parts are manufactured by Diodes Incorporated with identical electrical specifications and SOT-23-3 packaging. The designation difference reflects packaging format or supply chain variant. No functional or performance difference exists between the two part numbers.

Q: Are there any compliance or regulatory differences between these substitute parts?

A: No. Both DDZX15-13 and DDZX15-7 carry identical RoHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity ratings. Both are classified as active products with no end-of-life restrictions.

Q: What is the operating temperature range for these Zener diodes?

A: The operating temperature range is -65°C to 150°C for both the DDZX15-13 and DDZX15-7. This range covers industrial and commercial temperature environments.

Q: Can these 15 V Zener diodes be used in applications requiring different voltage ratings?

A: No. These components are specified for 15 V nominal zener voltage with ±3% tolerance. Use only in circuits designed for 15 V regulation or reference voltage applications. Different voltage ratings require different part numbers.

Q: What is the maximum power dissipation for the DDZX15-13 and DDZX15-7?

A: Both parts are rated for 300 mW maximum power dissipation. Circuit design must ensure that power dissipation does not exceed this limit under worst-case operating conditions.

Q: Is the SOT-23-3 package suitable for automated assembly?

A: Yes. The SOT-23-3 package is a standard surface mount package compatible with automated pick-and-place and reflow soldering processes. Both DDZX15-13 and DDZX15-7 are supplied in tape & reel format for automated assembly.
