SMBG5.0A-M3/52 Equivalent & Substitute Parts

Part Overview

The SMBG5.0A-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 protection applications. The device features a 5V reverse standoff voltage with a 9.2V maximum clamping voltage and 65.2A peak pulse current capability in a compact DO-215AA (SMB) package. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, the SMBG5.0A-M3/52 remains in production. Equivalent substitute parts may be required due to inventory availability, regional supplier preferences, or procurement lead time considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBG5.0A-M3/52 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 5V (typ)
• Voltage - Breakdown: 6.4V (min)
• Voltage - Clamping: 9.2V (max @ Ipp)
• Current - Peak Pulse: 65.2A (10/1000µs)
• Power - Peak Pulse: 600W
• Package / Case: DO-215AA, SMB Gull Wing
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional (1 channel)
• Series: TransZorb®

The SMBG5.0A-E3/52 meets all these criteria and is therefore a direct functional equivalent. Both parts share identical electrical performance specifications, the same package footprint, and equivalent manufacturing standards.

Parameter Comparison

*Operating temperature range differs. SMBG5.0A-M3/52 supports -65°C to 175°C; SMBG5.0A-E3/52 supports -55°C to 150°C. Selection depends on application temperature requirements.

Engineering Selection Recommendations

Both SMBG5.0A-M3/52 and SMBG5.0A-E3/52 are active products with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

1. Operating temperature requirements: If the application requires operation below -55°C or above 150°C, the SMBG5.0A-M3/52 is required due to its extended temperature range (-65°C to 175°C).

2. Inventory and lead time: SMBG5.0A-E3/52 has higher stock availability (2150 pcs vs. 770 pcs), making it preferable for immediate procurement when temperature constraints are not limiting.

3. Regulatory compliance: Both parts meet REACH and RoHS3 requirements with identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can SMBG5.0A-E3/52 be used as a direct replacement for SMBG5.0A-M3/52?

A: Yes, for applications operating within -55°C to 150°C. Both parts are electrically identical with matching voltage ratings (5V standoff, 9.2V clamping), current ratings (65.2A peak pulse), and package specifications (DO-215AA SMB). If your application requires operation outside this temperature range, the SMBG5.0A-M3/52 is necessary.

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

A: The M3 and E3 designations indicate different manufacturing batches or tape reels from Vishay. They do not reflect functional differences in the diode itself. The electrical and mechanical specifications are identical.

Q: Are both parts suitable for surface-mount assembly?

A: Yes. Both SMBG5.0A-M3/52 and SMBG5.0A-E3/52 use the DO-215AA (SMB) Gull Wing package and are supplied in Tape & Reel (TR) format for automated surface-mount assembly.

Q: What applications are these TVS diodes designed for?

A: Both parts are rated for general-purpose transient voltage suppression. They protect circuits from voltage spikes and transient overvoltage events in 5V systems.

Q: Do these parts have any moisture sensitivity concerns?

A: No. Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control measures.
