Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMCG6.0-E3/9AT is determined by the following critical electrical and mechanical parameters:

• Voltage Rating: Reverse standoff voltage of 6V and breakdown voltage minimum of 6.67V
• Clamping Voltage: Maximum clamping voltage at peak pulse current
• Peak Pulse Current: 10/1000µs pulse rating capability
• Power Dissipation: Peak pulse power rating of 1500W
• Package Compatibility: DO-215AB surface mount package with SMC Gull Wing configuration
• Temperature Range: Operating range of -55°C to 150°C
• Device Type: Unidirectional Zener TVS diode

The substitute part SMCG6.0A-E3/9AT maintains identical voltage ratings, package configuration, and temperature specifications while providing improved peak pulse current handling (145.6A versus 131.6A) and a lower clamping voltage (10.3V versus 11.4V).

Parameter Comparison

Engineering Selection Recommendations

The SMCG6.0A-E3/9AT is the direct substitute for the obsolete SMCG6.0-E3/9AT. Both components share identical voltage ratings, package configuration, and temperature operating range. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The SMCG6.0A-E3/9AT provides enhanced performance characteristics with increased peak pulse current capability (145.6A versus 131.6A) and improved clamping voltage performance (10.3V versus 11.4V). Both parts maintain equivalent power dissipation ratings of 1500W and are fully compliant with ROHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can SMCG6.0A-E3/9AT be used as a direct replacement for SMCG6.0-E3/9AT?

A: Yes. Both components share identical reverse standoff voltage (6V), breakdown voltage (6.67V minimum), operating temperature range (-55°C to 150°C), and DO-215AB surface mount package configuration. The substitute part is electrically and mechanically compatible.

Q: What are the differences between these two parts?

A: The primary differences are product status and performance characteristics. SMCG6.0A-E3/9AT is active production while SMCG6.0-E3/9AT is obsolete. The substitute provides higher peak pulse current (145.6A versus 131.6A) and lower maximum clamping voltage (10.3V versus 11.4V).

Q: Are there packaging differences?

A: Both parts use the DO-215AB SMC Gull Wing surface mount package. The SMCG6.0A-E3/9AT is supplied in Tape & Reel (TR) packaging, while the original part does not specify packaging format. Both are compatible with standard surface mount assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SMCG6.0-E3/9AT and SMCG6.0A-E3/9AT are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level).

Q: What is the basis for substitution compatibility?

A: Substitution is based on matching voltage ratings (6V standoff, 6.67V minimum breakdown), clamping voltage performance, peak pulse current capability, power dissipation rating, package type, and operating temperature range. All critical parameters align between the two components.
