Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBG5.0CA-M3/52 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 5V (exact match required)
• Voltage - Breakdown (Min): 6.4V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 9.2V (exact match required)
• Current - Peak Pulse (10/1000µs): 65.2A (exact match required)
• Power - Peak Pulse: 600W (exact match required)
• Package / Case: DO-215AA, SMB Gull Wing (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The identified substitute part maintains all electrical specifications and physical packaging requirements. Differences in operating temperature range and inventory levels do not affect functional substitutability within the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both SMBG5.0CA-M3/52 and SMBG5.0CA-E3/52 are active products with identical electrical performance specifications and full RoHS3 compliance. Selection between these parts should be based on the following factors:

The SMBG5.0CA-M3/52 supports an extended operating temperature range of -65°C to 175°C, making it suitable for applications requiring operation at lower ambient temperatures or higher junction temperatures. The SMBG5.0CA-E3/52 operates within -55°C to 150°C, which covers standard industrial and commercial temperature ranges. Both devices maintain equivalent transient suppression performance, clamping characteristics, and peak pulse handling capability. Component selection should align with the specific thermal operating environment of the target application.

Frequently Asked Questions (FAQ)

Q: Can SMBG5.0CA-E3/52 be used as a direct replacement for SMBG5.0CA-M3/52?

A: Yes, SMBG5.0CA-E3/52 is electrically and mechanically equivalent for all transient voltage suppression parameters. The primary difference is the operating temperature range. If your application operates within -55°C to 150°C, this substitute is fully compatible.

Q: What is the significance of the different operating temperature ranges?

A: The SMBG5.0CA-M3/52 supports -65°C to 175°C, while SMBG5.0CA-E3/52 supports -55°C to 150°C. Select the part matching your application's thermal requirements. Extended temperature range parts are necessary only if operation below -55°C or above 150°C is required.

Q: Are the package and mounting specifications identical?

A: Yes. Both parts use the DO-215AA (SMB Gull Wing) surface-mount package with identical physical dimensions and PCB footprint compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SMBG5.0CA-M3/52 and SMBG5.0CA-E3/52 are ROHS3 compliant, REACH unaffected, and classified as EAR99 with identical HTSUS codes.

Q: What are the key electrical parameters that define substitutability?

A: Substitutability is determined by exact equivalence in reverse standoff voltage (5V), breakdown voltage (6.4V minimum), clamping voltage (9.2V maximum), peak pulse current (65.2A), and peak pulse power (600W). Both parts meet these specifications identically.
