Substitute Part Grouping Explanation

Substitution of the DDZX11C-13 is determined by electrical and mechanical parameter equivalence. The critical parameters that define substitutability are:

• Zener voltage rating: 11 V nominal
• Tolerance specification: ±3%
• Maximum power dissipation: 300 mW
• Impedance (Max): 10 Ohms
• Reverse leakage current: 100 nA @ 8.4 V
• Forward voltage: 900 mV @ 10 mA
• Operating temperature range: -65°C ~ 150°C
• Package type: SOT-23-3 surface mount configuration

The DDZX11C-7 meets all electrical and mechanical requirements for direct substitution. Both parts share identical electrical specifications and package geometry, with the primary distinction being packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The DDZX11C-7 is the direct electrical and mechanical equivalent to the DDZX11C-13. Both components are manufactured by Diodes Incorporated and share identical electrical specifications, operating temperature range, and SOT-23-3 package configuration.

The primary distinction between these parts is product status and packaging format. The DDZX11C-13 is classified as obsolete, while the DDZX11C-7 maintains active product status. The DDZX11C-7 is supplied in Tape & Reel (TR) packaging format, whereas the DDZX11C-13 packaging format is not specified in the provided data.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. The MSL rating of 1 (Unlimited) for both components indicates no moisture sensitivity restrictions during storage and handling.

For new designs and production applications, the DDZX11C-7 is the appropriate selection due to its active product status and guaranteed availability. For legacy system repairs or maintenance where the original DDZX11C-13 is unavailable, the DDZX11C-7 provides complete functional and mechanical compatibility.
