SMBG6.5A-M3/52 Equivalent & Substitute Parts

Part Overview

The SMBG6.5A-M3/52 is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, part of the TransZorb® series. This surface mount component is designed for general-purpose transient voltage suppression applications, featuring a 6.5V reverse standoff voltage and 11.2V maximum clamping voltage. The device is actively manufactured and ROHS3 compliant. Substitute parts are identified when electrical parameters, mechanical compatibility, and compliance certifications remain equivalent across manufacturing variants or packaging options.

Substitute Part Grouping Explanation

Substitution eligibility for the SMBG6.5A-M3/52 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 6.5V (Typ)
• Voltage - Clamping (Max) @ Ipp: 11.2V
• Current - Peak Pulse (10/1000µs): 53.6A
• Power - Peak Pulse: 600W
• Package / Case: DO-215AA, SMB Gull Wing
• Mounting Type: Surface Mount
• Series: TransZorb®
• Manufacturer: Vishay General Semiconductor - Diodes Division

The SMBG6.5A-E3/52 meets all substitution criteria as a direct equivalent within the same product family, differing only in packaging designation (E3 vs. M3 tape reel variant) and operating temperature range specification.

Parameter Comparison

Engineering Selection Recommendations

Both SMBG6.5A-M3/52 and SMBG6.5A-E3/52 are active products from Vishay with identical electrical performance specifications and mechanical compatibility. Selection between these parts should be based on:

• Tape reel packaging variant availability (M3 vs. E3 designation)
• Operating temperature range requirements: The SMBG6.5A-M3/52 supports -65°C to 175°C, while the SMBG6.5A-E3/52 supports -55°C to 150°C
• Supply chain and inventory considerations
• Both parts maintain ROHS3 compliance and identical regulatory certifications

For applications requiring the full -65°C to 175°C operating range, the SMBG6.5A-M3/52 is the appropriate selection. For applications within the -55°C to 150°C range, either part is functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can SMBG6.5A-E3/52 be used as a direct replacement for SMBG6.5A-M3/52?

A: Yes, provided the application operating temperature does not exceed -55°C to 150°C. The SMBG6.5A-M3/52 offers an extended lower temperature limit (-65°C vs. -55°C) and higher upper temperature limit (175°C vs. 150°C). If your circuit operates within the E3 variant's temperature range, substitution is electrically and mechanically valid.

Q: What does the M3 and E3 designation indicate?

A: These designations refer to Vishay's tape reel packaging variants. Both parts are identical in electrical performance and physical package (DO-215AA, SMB Gull Wing). The difference is in the reel configuration and handling specifications for automated assembly.

Q: Are the electrical parameters identical between these parts?

A: Yes. Both parts share identical voltage ratings (6.5V reverse standoff, 11.2V clamping), peak pulse current (53.6A), and power dissipation (600W). They are functionally equivalent for transient voltage suppression applications.

Q: What compliance certifications apply to both parts?

A: Both SMBG6.5A-M3/52 and SMBG6.5A-E3/52 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts use identical DO-215AA surface mount packages with SMB Gull Wing configuration. PCB footprints, solder reflow profiles, and assembly processes are identical. Substitution requires no design changes.
