Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMCG6.5CA-M3/9AT are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

• Identical voltage ratings: Reverse standoff voltage of 6.5V, breakdown voltage minimum of 7.22V, and clamping voltage maximum of 11.2V
• Identical current specifications: Peak pulse current of 133.9A at 10/1000µs pulse width
• Identical power dissipation: 1500W peak pulse power
• Identical package type: DO-215AB surface mount configuration with SMC Gull Wing footprint
• Identical bidirectional channel configuration: Single channel Zener diode
• Identical operating temperature range: -55°C to 150°C junction temperature
• Identical compliance certifications: ROHS3 compliant, REACH unaffected status

Variations in tape reel configurations (M3/9AT versus E3/57T) represent different supplier packaging and reel specifications but do not affect electrical performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SMCG6.5CA-M3/9AT and SMCG6.5CA-E3/57T are active production components from Vishay General Semiconductor - Diodes Division with identical electrical specifications and mechanical packaging. Selection between these parts is determined by supply chain availability and tape reel configuration requirements rather than functional performance.

The SMCG6.5CA-E3/57T offers higher inventory availability (4099 pieces) compared to the SMCG6.5CA-M3/9AT (731 pieces). Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for storage and handling.

Frequently Asked Questions (FAQ)

Q: Are SMCG6.5CA-M3/9AT and SMCG6.5CA-E3/57T electrically interchangeable?

A: Yes. Both parts are identical Zener TVS diodes with matching voltage ratings (6.5V reverse standoff, 7.22V breakdown minimum, 11.2V clamping maximum), current specifications (133.9A peak pulse), and power dissipation (1500W). They function identically in circuit applications.

Q: What do the tape reel designations M3/9AT and E3/57T represent?

A: These designations specify supplier-specific tape reel configurations and packaging formats. They do not affect electrical performance or PCB footprint compatibility. The difference relates to reel diameter, tape width, and component spacing for automated assembly equipment.

Q: Can I substitute SMCG6.5CA-E3/57T for SMCG6.5CA-M3/9AT in existing designs?

A: Yes. The parts share identical DO-215AB surface mount package geometry, electrical specifications, and operating characteristics. No circuit redesign or PCB layout modification is required.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both SMCG6.5CA-M3/9AT and SMCG6.5CA-E3/57T are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions. No moisture baking or special humidity control is required prior to assembly, simplifying inventory management and reducing production constraints.
