Key Parameters

Substitute Part Grouping Explanation

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

• Voltage - Reverse Standoff (Typ): 6.5V
• Voltage - Breakdown (Min): 7.22V
• 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
• Unidirectional Channels: 1
• Type: Zener

The substitute part SMBG6.5A-E3/52 maintains identical electrical performance specifications and mechanical compatibility. Both parts are manufactured by Vishay General Semiconductor - Diodes Division within the TransZorb® series and share the same base product number (SMBG6.5). The primary distinction lies in packaging configuration (tape & reel variant designation) and operating temperature range, which does not affect functional substitution in applications within the overlapping temperature envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBG6.5A-M3/5B and SMBG6.5A-E3/52 are active production components with ROHS3 compliance and unlimited moisture sensitivity classification. Selection between these parts should be based on application operating temperature requirements and inventory availability.

For applications operating within the temperature range of -55°C to 150°C (TJ), either part is functionally equivalent. For applications requiring operation below -55°C or above 150°C (TJ), the SMBG6.5A-M3/5B with its extended temperature range of -65°C to 175°C (TJ) is the appropriate selection.

The SMBG6.5A-E3/52 offers significantly higher inventory availability (12200 pieces versus 698 pieces), which may support procurement timelines and supply chain resilience for high-volume applications.

Frequently Asked Questions (FAQ)

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

A: Yes, for applications operating within the temperature range of -55°C to 150°C (TJ). Both parts share identical electrical specifications (6.5V reverse standoff, 11.2V clamping voltage, 53.6A peak pulse current, 600W peak pulse power) and mechanical compatibility (DO-215AA package, surface mount configuration). The primary difference is the operating temperature range; the SMBG6.5A-M3/5B supports extended low-temperature operation to -65°C.

Q: What is the significance of the packaging designation difference (M3/5B versus E3/52)?

A: The packaging designation indicates the tape & reel configuration and supplier variant. Both designations represent the same physical component in DO-215AA (SMB Gull Wing) surface mount package. The difference reflects supplier-specific packaging and handling specifications but does not affect electrical performance or mechanical fit.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, carry unlimited moisture sensitivity level (MSL 1), and are manufactured by Vishay General Semiconductor - Diodes Division within the active TransZorb® series. Compliance and certification status are identical.

Q: Which part should be selected for high-volume procurement?

A: The SMBG6.5A-E3/52 is recommended for high-volume applications due to significantly higher inventory availability (12200 pieces in stock compared to 698 pieces). This part supports procurement flexibility and supply chain continuity for volume production.

Q: What is the base product number, and why is it relevant?

A: The base product number is SMBG6.5. Both the SMBG6.5A-M3/5B and SMBG6.5A-E3/52 share this base designation, confirming they are variants of the same core product within the TransZorb® series. This commonality reinforces their functional equivalence.
