• Voltage - Reverse Standoff: 9V (nominal)
• Voltage - Clamping (Max) @ Ipp: 15.4V
• Current - Peak Pulse: 39A
• Power - Peak Pulse: 600W
• Package / Case: DO-215AA, SMB Gull Wing
• Mounting Type: Surface Mount
• Base Product Number: SMBG9.0

The substitute part SMBG9.0CA-E3/52 maintains identical electrical specifications and package configuration, ensuring direct functional compatibility in circuit applications requiring 9V TVS protection.

Parameter Comparison

Engineering Selection Recommendations

Both SMBG9.0CA-M3/5B and SMBG9.0CA-E3/52 are Active products with ROHS3 Compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component deployment. The primary distinction between these parts is the operating temperature range: the SMBG9.0CA-M3/5B supports -65°C to 175°C, while the SMBG9.0CA-E3/52 operates within -55°C to 150°C. Selection between these substitutes depends on the thermal environment of the target application. For applications requiring extended low-temperature operation below -55°C or sustained high-temperature operation above 150°C, the SMBG9.0CA-M3/5B is the appropriate choice. For standard industrial and commercial temperature ranges, either part provides equivalent electrical protection and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can SMBG9.0CA-E3/52 be used as a direct replacement for SMBG9.0CA-M3/5B?

A: Yes, for applications operating within the -55°C to 150°C temperature range. Both parts share identical electrical specifications (9V standoff, 15.4V clamping, 39A peak pulse current) and the same DO-215AA package configuration. The substitution is valid when the application's thermal environment does not exceed the SMBG9.0CA-E3/52 operating limits.

Q: What is the difference between these two part numbers?

A: The primary difference is the operating temperature range. SMBG9.0CA-M3/5B operates from -65°C to 175°C, while SMBG9.0CA-E3/52 operates from -55°C to 150°C. All other electrical and mechanical parameters are identical.

Q: Are both parts compatible with the same PCB layout and footprint?

A: Yes. Both parts use the DO-215AA (SMB Gull Wing) package with identical mechanical dimensions and pin configuration, ensuring compatibility with the same PCB footprint and assembly process.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SMBG9.0CA-M3/5B and SMBG9.0CA-E3/52 are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should I select for a new design?

A: Selection depends on the application's operating temperature requirements. If the design operates within -55°C to 150°C, either part is suitable. For applications requiring extended temperature range capability, specify SMBG9.0CA-M3/5B. For standard commercial and industrial applications, SMBG9.0CA-E3/52 provides equivalent protection at potentially different availability or cost.
