Key Parameters

Substitute Part Grouping Explanation

Substitution of the GDZT2R6.8B is determined by electrical and mechanical parameter equivalence. The critical parameters governing substitution are:

• Zener Voltage (Vz): 6.8 V nominal with ±5% tolerance
• Power Rating: 100 mW maximum
• Reverse Leakage Current: 500 nA @ 3.5 V
• Operating Temperature: 150°C maximum junction temperature
• Mounting Configuration: Surface mount technology
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The SDZT15R6.8 meets all electrical specifications and regulatory requirements. While the package designation differs (SMD0603 versus GMD2), both represent equivalent 0603 metric surface mount form factors suitable for the same PCB footprints and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The SDZT15R6.8 is the direct functional equivalent for the obsolete GDZT2R6.8B. Both components are manufactured by Rohm Semiconductor and share identical electrical specifications across all critical parameters: 6.8 V zener voltage, ±5% tolerance, 100 mW power rating, and 500 nA reverse leakage current at 3.5 V.

The SDZT15R6.8 carries active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards. The MSL rating of 1 (Unlimited) for both components indicates no moisture sensitivity constraints during storage or handling.

Package compatibility is confirmed: both the GMD2 and SMD0603 designations represent equivalent 0603 metric surface mount form factors with identical PCB footprints and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can the SDZT15R6.8 be used as a direct replacement for the GDZT2R6.8B?

A: Yes. The SDZT15R6.8 is electrically and mechanically equivalent. All critical parameters—zener voltage, tolerance, power rating, reverse leakage current, and operating temperature—are identical. Both components use compatible 0603 metric surface mount packages.

Q: What is the difference between the GMD2 and SMD0603 package designations?

A: GMD2 and SMD0603 are equivalent designations for the same 0603 metric surface mount package format. Both represent a 2-terminal surface mount diode package with identical physical dimensions and PCB footprints.

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

A: No. Both the GDZT2R6.8B and SDZT15R6.8 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Regulatory status is identical.

Q: Why is the GDZT2R6.8B listed as obsolete?

A: The GDZT2R6.8B has been discontinued by Rohm Semiconductor. The SDZT15R6.8 is the active equivalent product that replaces it in the manufacturer's current product line.

Q: Are there any thermal or electrical performance differences?

A: No. Both components operate at the same maximum junction temperature of 150°C and deliver identical electrical performance across all specified parameters.

Q: What packaging options are available for the SDZT15R6.8?

A: The SDZT15R6.8 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both manual and automated assembly processes.
