Parameter Comparison

Engineering Selection Recommendations

Both SMCG36CA-M3/9AT and SMCG36CA-E3/57T are Active products with full RoHS3 compliance and identical electrical specifications. Selection between these parts should be based on availability and supply chain requirements. The SMCG36CA-E3/57T currently maintains higher inventory levels (2010 Pcs) compared to SMCG36CA-M3/9AT (693 Pcs), making it suitable for applications where lead time optimization is a consideration. Both parts carry REACH Unaffected status and are classified under ECCN EAR99, with identical HTSUS coding (8541.10.0080). No technical differentiation exists between these components for circuit design purposes.

Frequently Asked Questions (FAQ)

Q: Can SMCG36CA-E3/57T be used as a direct replacement for SMCG36CA-M3/9AT?

A: Yes. Both parts are electrically and mechanically identical. They share the same voltage ratings (36V reverse standoff, 40V breakdown minimum, 58.1V clamping maximum), current handling (25.8A peak pulse), power dissipation (1500W), package type (DO-215AB SMC Gull Wing), and operating temperature range (-55°C to 150°C). No circuit modifications are required.

Q: What determines substitution eligibility for this TVS diode?

A: Substitution is valid when the alternative part maintains identical specifications across voltage parameters (reverse standoff, breakdown, and clamping), peak pulse current rating, power dissipation, package configuration, and operating temperature range. Both parts must be from the same manufacturer series and maintain equivalent compliance certifications.

Q: Are there any packaging or handling differences between these parts?

A: Both parts are supplied in Tape & Reel (TR) packaging with identical Moisture Sensitivity Level (MSL 1 - Unlimited). No special handling differences exist between the two part numbers.

Q: What is the significance of the different part number suffixes (-M3/9AT vs -E3/57T)?

A: The suffix variations indicate different tape and reel configurations or manufacturing date codes from Vishay. These designations do not affect electrical performance or functional compatibility. The core specifications remain identical.

Q: Are both parts suitable for general-purpose transient voltage suppression applications?

A: Yes. Both SMCG36CA-M3/9AT and SMCG36CA-E3/57T are rated for general-purpose applications and provide identical protection characteristics for 36V nominal circuits with transient overvoltage events.
