Substitute Part Grouping Explanation

Substitution for the SMBG24A/52 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 24V
• Voltage - Breakdown (Min): 26.7V
• Voltage - Clamping (Max) @ Ipp: 38.9V
• Current - Peak Pulse (10/1000µs): 15.4A
• Power - Peak Pulse: 600W
• Unidirectional Channels: 1
• Package / Case: DO-215AA, SMB Gull Wing
• Operating Temperature Range: -55°C ~ 150°C (TJ)

The SMBG24A-E3/52 meets all electrical and mechanical specifications required for direct substitution. Differences in product status, packaging format (Tape & Reel vs. bulk), and RoHS compliance do not affect functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The SMBG24A-E3/52 is the direct functional equivalent for the obsolete SMBG24A/52. Both parts share identical electrical specifications and mechanical packaging, ensuring pin-for-pin and functional compatibility in circuit designs.

The primary distinction is product status: SMBG24A-E3/52 is actively manufactured and supported, whereas SMBG24A/52 is obsolete. For new designs or ongoing production requiring long-term component availability, SMBG24A-E3/52 is the appropriate selection.

SMBG24A-E3/52 carries ROHS3 compliance, whereas SMBG24A/52 is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can SMBG24A-E3/52 be used as a direct replacement for SMBG24A/52?

A: Yes. Both parts are electrically and mechanically identical. All voltage ratings, current specifications, temperature ranges, and package dimensions match exactly. No circuit modifications are required.

Q: What is the difference between SMBG24A/52 and SMBG24A-E3/52?

A: The primary differences are product status (obsolete vs. active), packaging format (bulk vs. Tape & Reel), and RoHS compliance status (non-compliant vs. ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Does the Tape & Reel packaging of SMBG24A-E3/52 affect circuit performance?

A: No. Packaging format (Tape & Reel vs. bulk) does not affect component performance or electrical characteristics. It impacts procurement, handling, and assembly processes only.

Q: Are there any temperature or operating condition differences between these parts?

A: No. Both parts operate across the identical temperature range of -55°C to 150°C (TJ) and are rated for the same peak pulse power of 600W.

Q: Which part should be selected for new designs?

A: SMBG24A-E3/52 should be selected for new designs. It is actively manufactured, carries current RoHS compliance certification, and ensures long-term availability and support.
