SMBG24A-M3/52 Equivalent & Substitute Parts

Part Overview

The SMBG24A-M3/52 is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, part of the TransZorb® series. This surface-mount component is designed for general-purpose transient voltage suppression applications. The device is currently in active production status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory availability, supply chain considerations, or design flexibility within the allowed parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBG24A-M3/52 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 24V
• Voltage - Breakdown (Min): 26.7V
• Voltage - Clamping (Max) @ Ipp: 38.9V
• Current - Peak Pulse (10/1000µs): 15.4A
• Power - Peak Pulse: 600W
• Package / Case: DO-215AA, SMB Gull Wing
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional (1 channel)
• Series: TransZorb®

The identified substitute part SMBG24A-E3/52 maintains identical electrical specifications and mechanical compatibility, differing only in manufacturing date code designation and operating temperature range. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share the same base product number (SMBG24).

Parameter Comparison

Engineering Selection Recommendations

Both SMBG24A-M3/52 and SMBG24A-E3/52 are active production components with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

SMBG24A-M3/52 is suitable for applications requiring the extended operating temperature range of -65°C to 175°C (TJ).

SMBG24A-E3/52 is suitable for applications operating within the -55°C to 150°C (TJ) temperature range and offers higher current inventory availability (4384 pcs vs. 1065 pcs).

Both parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity classification. Selection should be based on specific application temperature requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can SMBG24A-E3/52 replace SMBG24A-M3/52 in all applications?

A: SMBG24A-E3/52 is electrically and mechanically equivalent to SMBG24A-M3/52. However, the operating temperature range differs: SMBG24A-E3/52 operates from -55°C to 150°C (TJ), while SMBG24A-M3/52 operates from -65°C to 175°C (TJ). Substitution is valid only if the application temperature requirements fall within the -55°C to 150°C range.

Q: Are the package and mounting specifications identical?

A: Yes. Both parts use the DO-215AA (SMB Gull Wing) package in surface-mount configuration with Tape & Reel (TR) packaging. PCB layout and assembly processes are interchangeable.

Q: What are the key electrical parameters that define substitution?

A: Substitution is determined by matching: Voltage - Reverse Standoff (24V), Voltage - Breakdown (26.7V minimum), Voltage - Clamping (38.9V maximum), Current - Peak Pulse (15.4A), and Power - Peak Pulse (600W). All other parameters must also align.

Q: Do both parts have the same compliance certifications?

A: Yes. Both SMBG24A-M3/52 and SMBG24A-E3/52 are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) classification.

Q: What is the difference between the M3 and E3 designations?

A: The M3 and E3 designations represent different manufacturing date codes from Vishay. They do not indicate functional differences in electrical or mechanical performance within the specified parameter ranges.
