• Voltage - Clamping (Max) @ Ipp: 24.4V
• Current - Peak Pulse (10/1000µs): 24.6A
• Power - Peak Pulse: 600W
• Package / Case: DO-215AA, SMB Gull Wing
• Bidirectional Channels: 1
• Type: Zener

The substitute part SMBG15CA-E3/52 meets all electrical and mechanical requirements for direct substitution. Both parts are manufactured by Vishay General Semiconductor - Diodes Division within the TransZorb® series and share identical functional specifications for transient voltage suppression applications.

Parameter Comparison

Engineering Selection Recommendations

Both SMBG15CA-M3/5B and SMBG15CA-E3/52 are active production components manufactured by Vishay General Semiconductor - Diodes Division. Both parts carry ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings, meeting regulatory and environmental requirements for industrial and commercial applications.

The primary distinction between these parts is the operating temperature range. The SMBG15CA-M3/5B supports -65°C to 175°C, while the SMBG15CA-E3/52 operates within -55°C to 150°C. Component selection should be based on the specific thermal requirements of the target application. For applications requiring extended low-temperature operation below -55°C or sustained high-temperature operation above 150°C, the SMBG15CA-M3/5B is the appropriate choice. For standard industrial temperature ranges, either part is functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can SMBG15CA-E3/52 be used as a direct replacement for SMBG15CA-M3/5B?

A: Yes, for applications operating within the -55°C to 150°C temperature range.

The packaging and mounting type are identical (DO-215AA, SMB Gull Wing surface mount).

Q: What is the key difference between these two parts?

A: The operating temperature range differs. SMBG15CA-M3/5B operates from -65°C to 175°C, while SMBG15CA-E3/52 operates from -55°C to 150°C. All other electrical and mechanical parameters are equivalent.

Q: Are both parts suitable for general-purpose transient voltage protection?

A: Yes. Both parts are rated for general-purpose applications with identical transient suppression characteristics: 15V reverse standoff voltage, 24.4V maximum clamping voltage, and 24.6A peak pulse current.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both SMBG15CA-M3/5B and SMBG15CA-E3/52 are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, provided the application's operating temperature range does not exceed the limits of the selected part. Both parts use identical DO-215AA packaging and SMB Gull Wing surface-mount configuration, ensuring mechanical and electrical compatibility on the same PCB layout.
