Key Parameters

Substitute Part Grouping Explanation

Substitution of the SM6T100A-M3/52 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 85.5V
• Voltage - Breakdown (Min): 95V
• Voltage - Clamping (Max) @ Ipp: 137V
• Package / Case: DO-214AA, SMB (surface mount)
• Unidirectional Channels: 1
• Type: Zener
• Mounting Type: Surface Mount

Substitute parts must maintain identical voltage ratings and mechanical compatibility. Variations in peak pulse current (4.4A to 7.3A) and power dissipation (600W to 1000W) are permissible when the substitute part meets or exceeds the original specification. Operating temperature range and compliance certifications are secondary selection criteria.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain identical voltage specifications and package compatibility with the SM6T100A-M3/52. Selection among equivalents is based on the following criteria:

P6SMB100A-E3/52 (Vishay): Direct equivalent from the same manufacturer. Identical electrical specifications and operating temperature range. Highest inventory availability (22,800 pcs). Recommended for direct replacement without design modification.

1KSMB100A (Taiwan Semiconductor): Exceeds original specifications with 7.3A peak pulse current and 1000W power dissipation versus 4.4A and 600W. Extended upper operating temperature to 175°C. Suitable for applications requiring enhanced transient suppression capability. ROHS3 compliant.

P6SMB100A (Eaton): Equivalent electrical performance with 4.5A peak pulse current. Available in Cut Tape and Digi-Reel® packaging. RoHS compliant. Operating temperature range -55°C to 150°C. Suitable for general-purpose applications.

SZP6SMB100AT3G (Littelfuse): Meets all electrical specifications with automotive-grade qualification (AEC-Q101). Specified capacitance of 215pF @ 1MHz. Operating temperature range -65°C to 150°C matches original part. Recommended for automotive and mission-critical applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute SM6T100A-M3/52 with P6SMB100A-E3/52? A: Yes. Both parts are manufactured by Vishay and share identical voltage ratings (85.5V standoff, 95V breakdown, 137V clamping), peak pulse current (4.4A), and operating temperature range (-65°C to 150°C). Package and mounting type are identical (DO-214AA, SMB, surface mount).

Q: What is the difference between SM6T100A-M3/52 and 1KSMB100A? A: The 1KSMB100A provides higher peak pulse current (7.3A versus 4.4A) and power dissipation (1000W versus 600W). Operating temperature range extends to 175°C. Voltage specifications are identical. The 1KSMB100A is suitable for applications requiring enhanced transient suppression.

Q: Are all substitute parts RoHS compliant? A: Four of five substitute parts are ROHS3 compliant. P6SMB100A (Eaton) is RoHS compliant. All parts meet environmental compliance requirements.

Q: Can I use SZP6SMB100AT3G in non-automotive applications? A: Yes. SZP6SMB100AT3G meets all electrical and mechanical specifications for the SM6T100A-M3/52. Automotive-grade qualification (AEC-Q101) indicates higher reliability standards and does not restrict use in general-purpose applications.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging formats do not affect electrical performance. Selection is based on manufacturing and assembly process requirements.

Q: What is the operating temperature consideration when selecting a substitute? A: The SM6T100A-M3/52 operates from -65°C to 150°C. Substitute parts with identical or extended temperature ranges are fully compatible. The 1KSMB100A extends to 175°C and P6SMB100A (Eaton) operates to 150°C. Select based on application thermal requirements.
