Key Parameters

Substitute Part Grouping Explanation

Substitution of the DDZX6V8C-13 is determined by the following critical parameters:

• Zener Voltage (Vz): 6.8 V nominal
• Maximum Power Dissipation: 300 mW
• Package Type: SOT-23-3 surface mount
• Impedance (Zzt): 5 Ohms maximum
• Reverse Leakage Current: 100 nA @ 5 V
• Forward Voltage: 900 mV @ 10 mA maximum
• Operating Temperature Range: -65°C to 150°C
• Compliance: ROHS3, REACH Unaffected

The substitute part DDZX6V8C-7 shares identical electrical performance in zener voltage, power rating, package configuration, impedance, leakage current, forward voltage, and operating temperature range. The primary difference is the voltage tolerance specification (±3% versus ±2.56%), which remains within acceptable substitution parameters for applications where the tighter tolerance of the main part is not a design requirement.

Parameter Comparison

Engineering Selection Recommendations

Both the DDZX6V8C-13 and DDZX6V8C-7 are Active product status components manufactured by Diodes Incorporated. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Both components are rated for the full operating temperature range of -65°C to 150°C and share identical package, mounting, and thermal characteristics. Inventory availability and lead time considerations may influence part selection, as the DDZX6V8C-7 maintains higher stock levels (25,300 pieces) compared to the DDZX6V8C-13 (1,079 pieces).

Frequently Asked Questions (FAQ)

Q: Can DDZX6V8C-7 be used as a direct replacement for DDZX6V8C-13?

A: Yes, the DDZX6V8C-7 is electrically and mechanically compatible with the DDZX6V8C-13. Both parts share identical zener voltage (6.8 V), power rating (300 mW), package type (SOT-23-3), impedance (5 Ohms), and operating temperature range (-65°C to 150°C). The tolerance difference (±3% versus ±2.56%) is the only specification variance.

Q: What is the primary difference between these two part numbers?

A: The primary difference is the voltage tolerance specification. The DDZX6V8C-13 maintains ±2.56% tolerance, while the DDZX6V8C-7 specifies ±3% tolerance. All other electrical parameters, including zener voltage, power dissipation, impedance, leakage current, and forward voltage, are identical.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Both the DDZX6V8C-13 and DDZX6V8C-7 use the SOT-23-3 surface mount package and are compatible with standard SMT assembly equipment and reflow soldering processes. Moisture sensitivity level is identical (MSL 1 - Unlimited) for both parts.

Q: Which part should be selected for high-precision voltage regulation applications?

A: The DDZX6V8C-13 with ±2.56% tolerance is appropriate for applications requiring tighter voltage regulation accuracy. The DDZX6V8C-7 with ±3% tolerance is suitable for applications with less stringent tolerance requirements.

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

A: No. Both parts are ROHS3 compliant and REACH unaffected. They share identical regulatory status and are suitable for use in applications subject to these compliance requirements.

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

A: Both the DDZX6V8C-13 and DDZX6V8C-7 operate across the temperature range of -65°C to 150°C, providing identical thermal performance characteristics.
