SMBG24C-E3/52 Equivalent & Substitute Parts

Part Overview

The SMBG24C-E3/52 is a transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates as a unidirectional Zener diode in the TransZorb® series, designed for general-purpose transient voltage suppression applications. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement continuity. The SMBG24C-E3/52 provides 24V reverse standoff voltage with a 43V maximum clamping voltage and 14A peak pulse current capability in a compact DO-215AA (SMB) package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBG24C-E3/52 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Reverse standoff voltage: 24V (nominal)
• Breakdown voltage minimum: 26.7V
• Zener diode type with single bidirectional channel
• Peak pulse current capability: minimum 14A
• Peak pulse power: 600W
• Operating temperature range: -55°C to 150°C

Mechanical Compatibility Criteria:

• Surface mount package: DO-215AA (SMB Gull Wing)
• Supplier device package: SMBG (DO-215AA)

Compliance & Regulatory Criteria:

• RoHS3 compliance required
• REACH unaffected status
• MSL rating: 1 (Unlimited)

The SMBG24CA-E3/52 qualifies as a direct substitute based on matching all electrical standoff and breakdown voltage specifications, identical package geometry, and equivalent thermal operating range. While the clamping voltage and peak pulse current differ slightly (38.9V clamp, 15.4A peak pulse versus 43V clamp, 14A peak pulse), these variations remain within the functional tolerance band for general-purpose TVS applications sharing the same 24V standoff voltage class.

Parameter Comparison

Engineering Selection Recommendations

The SMBG24CA-E3/52 is the primary substitute for the obsolete SMBG24C-E3/52. Both components are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical compliance certifications: ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited). The substitute part carries active product status, ensuring long-term availability and supply chain continuity.

Both parts share identical reverse standoff voltage (24V), breakdown voltage minimum (26.7V), peak pulse power (600W), and operating temperature range (-55°C to 150°C). The SMBG24CA-E3/52 provides marginally improved performance with a lower clamping voltage (38.9V versus 43V) and higher peak pulse current capability (15.4A versus 14A), making it functionally compatible for applications designed around the SMBG24C-E3/52 specifications.

Mechanical compatibility is assured through identical DO-215AA (SMB Gull Wing) package geometry, enabling direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the SMBG24CA-E3/52 be used as a direct replacement for the SMBG24C-E3/52?

A: Yes. Both components share identical reverse standoff voltage (24V), breakdown voltage (26.7V minimum), peak pulse power (600W), operating temperature range (-55°C to 150°C), and DO-215AA package geometry. The substitute part is electrically and mechanically compatible for general-purpose TVS applications.

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

A: The SMBG24CA-E3/52 features a lower maximum clamping voltage (38.9V versus 43V) and higher peak pulse current capability (15.4A versus 14A). The substitute part also carries active product status, whereas the original is obsolete. Both maintain identical compliance certifications and thermal specifications.

Q: Are there packaging differences between the SMBG24C-E3/52 and SMBG24CA-E3/52?

A: Both components use the DO-215AA (SMB Gull Wing) surface mount package. The SMBG24CA-E3/52 is supplied in Tape & Reel (TR) packaging format, whereas the original part number does not specify packaging format in the provided data. PCB footprint compatibility is identical.

Q: What compliance certifications apply to the SMBG24CA-E3/52?

A: The substitute part maintains ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited), matching the original component's regulatory profile.

Q: Why is the SMBG24C-E3/52 listed as obsolete?

A: The original part has been discontinued by the manufacturer. The SMBG24CA-E3/52 represents the active equivalent within the same TransZorb® series, providing continued design support and procurement availability.
