SMBG6.0-E3/52 Equivalent & Substitute Parts

Part Overview

The SMBG6.0-E3/52 is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, part of the TransZorb® series. This component is designed for general-purpose transient voltage protection in surface-mount applications using the DO-215AA (SMB) package. The part is currently listed as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SMBG6.0-E3/52 is determined by strict equivalence across the following critical parameters:

• Reverse Standoff Voltage: 6V (Typ)
• Breakdown Voltage (Min): 6.67V
• Package Type: DO-215AA (SMB Gull Wing)
• Mounting Type: Surface Mount
• Unidirectional Configuration: 1 channel
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Series Classification: TransZorb®

The SMBG6.0A-E3/52 meets all substitution criteria. While this substitute exhibits different clamping voltage (10.3V vs. 11.4V) and peak pulse current (58.3A vs. 52.6A) specifications, these variations remain within the allowable parameter envelope for the SMBG6.0 base product number classification. Both components share identical standoff voltage, breakdown voltage, package configuration, and thermal operating range.

Parameter Comparison

Engineering Selection Recommendations

The SMBG6.0A-E3/52 is the direct substitute for the obsolete SMBG6.0-E3/52. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute maintains identical electrical classification (6V standoff, 6.67V minimum breakdown) and physical form factor (DO-215AA surface-mount package).

The substitute component is currently in active production status with confirmed inventory availability, whereas the original part is obsolete. Selection of the SMBG6.0A-E3/52 ensures continued access to functionally equivalent protection in the same package footprint without design modification.

Frequently Asked Questions (FAQ)

Q: Can the SMBG6.0A-E3/52 be used as a direct replacement for the SMBG6.0-E3/52 without PCB modifications?

A: Yes. Both components use the DO-215AA (SMB Gull Wing) package with identical pinout and footprint. No PCB layout changes are required.

Q: What are the key differences between these two parts?

A: The substitute exhibits a lower clamping voltage (10.3V vs. 11.4V) and higher peak pulse current capability (58.3A vs. 52.6A). Both remain within the SMBG6.0 base product specification envelope. The substitute is in active production; the original is obsolete.

Q: Are both parts RoHS compliant?

A: Yes. Both the SMBG6.0-E3/52 and SMBG6.0A-E3/52 are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What is the operating temperature range for these components?

A: Both components operate across -55°C to 150°C junction temperature (TJ), suitable for industrial and commercial applications.

Q: Does the packaging differ between the main part and substitute?

A: No. Both components are supplied in DO-215AA (SMB Gull Wing) surface-mount packages. The substitute is available in Tape & Reel (TR) packaging format, which is standard for active production components.
