• Voltage - Breakdown (Min): 40V
• Voltage - Clamping (Max) @ Ipp: 58.1V
• Current - Peak Pulse (10/1000µs): 10.3A
• Power - Peak Pulse: 600W
• Package / Case: DO-215AA, SMB Gull Wing
• Mounting Type: Surface Mount
• Unidirectional Channels: 1
• Series: TransZorb®
• Type: Zener
• Manufacturer: Vishay General Semiconductor - Diodes Division

Both parts share identical electrical performance specifications and mechanical packaging, confirming direct substitutability for circuit-level applications.

Parameter Comparison

*Operating temperature range of SMBG36A-E3/52 is narrower (-55°C to 150°C vs. -65°C to 175°C). Verify application requirements before substitution in extreme temperature environments.

Engineering Selection Recommendations

Both SMBG36A-M3/5B and SMBG36A-E3/52 are active-status products from Vishay General Semiconductor - Diodes Division and carry identical RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

1. Operating temperature requirements: The SMBG36A-M3/5B supports the extended temperature range of -65°C to 175°C, while the SMBG36A-E3/52 operates within -55°C to 150°C. Applications requiring operation below -55°C or above 150°C must use the SMBG36A-M3/5B.

2. Inventory and lead time: The SMBG36A-E3/52 currently has higher inventory availability (2100 pcs vs. 832 pcs), which may influence procurement decisions for high-volume requirements.

3. Packaging designation: Both parts use identical DO-215AA SMB Gull Wing surface-mount packaging and are supplied on Tape & Reel (TR).

Frequently Asked Questions (FAQ)

Q: Can SMBG36A-E3/52 be used as a direct replacement for SMBG36A-M3/5B?

A: Yes, for applications operating within the temperature range of -55°C to 150°C (TJ). Both parts are electrically and mechanically identical across all voltage, current, and power specifications. If your application requires operation outside this temperature window, the SMBG36A-M3/5B is required.

Q: What is the difference between the part numbers SMBG36A-M3/5B and SMBG36A-E3/52?

A: The differences are limited to the operating temperature range and packaging designation code. The M3/5B variant supports -65°C to 175°C, while the E3/52 variant supports -55°C to 150°C. All electrical performance parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes, both SMBG36A-M3/5B and SMBG36A-E3/52 are RoHS3 compliant and REACH unaffected.

Q: What is the package type for these TVS diodes?

A: Both parts use the DO-215AA package, commonly referred to as SMB Gull Wing, in surface-mount configuration. They are supplied on Tape & Reel (TR) for automated assembly.

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

A: Yes, both parts have identical mechanical packaging (DO-215AA, SMB Gull Wing) and mounting type (surface mount). PCB footprints and assembly processes are identical. Temperature range compatibility must be verified for your specific application.
