SMBJ160AE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMBJ160AE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This unidirectional Zener-type TVS diode operates with a reverse standoff voltage of 160V and provides clamping at 259V maximum, with a peak pulse current rating of 2.3A. The component is packaged in DO-214AA (SMB) format and supplied on tape and reel. The part maintains active product status and full compliance with RoHS3 and REACH regulations. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ160AE3/TR13 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - Reverse Standoff (Typ): 160V
• Voltage - Breakdown (Min): 178V
• Voltage - Clamping (Max) @ Ipp: 259V
• Current - Peak Pulse (10/1000µs): 2.3A or higher
• Power - Peak Pulse: 600W
• Type: Zener
• Unidirectional Channels: 1

Mechanical Equivalence Criteria:

• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitute parts are classified as either direct equivalents (identical electrical and mechanical specifications) or similar parts (meeting all critical parameters with minor variations in operating temperature range or peak pulse current within acceptable tolerance).

Parameter Comparison

Engineering Selection Recommendations

SMBJ160A (Meritek): This part is a direct electrical equivalent with identical voltage ratings (160V standoff, 178V breakdown, 259V clamping) and power dissipation (600W). Peak pulse current is 2.32A, which exceeds the 2.3A specification of the main part. The operating temperature range is -55°C to 150°C, which is narrower than the main part's -65°C to 150°C range. Both parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status. This substitute is suitable for applications where the lower temperature limit of -55°C is acceptable.

SMBJ160A-13-F (Diodes Incorporated): This part is a direct equivalent with identical electrical specifications (160V standoff, 178V breakdown, 259V clamping, 2.3A peak pulse current, 600W power dissipation). The operating temperature range is -55°C to 150°C. The part is supplied on tape and reel, matching the packaging format of the main part. Full compliance with ROHS3, MSL 1, and REACH unaffected status is maintained. This substitute is suitable for applications where the -55°C lower temperature limit is acceptable and tape and reel packaging is required.

Both substitute parts are active products with established inventory availability and meet all critical electrical, mechanical, and compliance requirements for direct substitution in general-purpose TVS diode applications.

Frequently Asked Questions (FAQ)

Q: Can SMBJ160A (Meritek) be used as a direct replacement for SMBJ160AE3/TR13?

A: SMBJ160A meets all critical electrical parameters (160V standoff, 259V clamping, 2.32A peak pulse current, 600W power dissipation) and mechanical requirements (DO-214AA SMB package, surface mount). The operating temperature range is -55°C to 150°C, which is narrower than the main part's -65°C to 150°C. Substitution is valid for applications operating within the -55°C to 150°C range.

Q: What is the difference between SMBJ160A-13-F and SMBJ160AE3/TR13?

A: Both parts share identical electrical specifications (160V standoff, 178V breakdown, 259V clamping, 2.3A peak pulse current, 600W power dissipation) and package format (DO-214AA SMB). The operating temperature range of SMBJ160A-13-F is -55°C to 150°C, compared to -65°C to 150°C for the main part. Both are supplied on tape and reel and maintain full ROHS3 and REACH compliance.

Q: Are all substitute parts available in tape and reel packaging?

A: SMBJ160A-13-F (Diodes Incorporated) is explicitly supplied on tape and reel (TR). SMBJ160A (Meritek) packaging format is not specified in the provided data. Confirm packaging requirements with the supplier before procurement.

Q: Do all substitute parts meet RoHS3 and REACH compliance?

A: Yes. SMBJ160A (Meritek) and SMBJ160A-13-F (Diodes Incorporated) are both ROHS3 compliant and REACH unaffected, matching the compliance status of SMBJ160AE3/TR13.

Q: What is the moisture sensitivity level (MSL) for substitute parts?

A: Both substitute parts carry MSL 1 (Unlimited), identical to the main part. This indicates unlimited shelf life under normal storage conditions.

Q: Can I use these substitutes in applications requiring operation below -55°C?

A: No. Both substitute parts are rated for -55°C minimum operating temperature. The main part SMBJ160AE3/TR13 is rated to -65°C. For applications requiring operation below -55°C, the main part or an alternative rated to -65°C must be used.

Q: Are there differences in peak pulse current between the main part and substitutes?

A: SMBJ160A (Meritek) is rated at 2.32A peak pulse current, which exceeds the main part's 2.3A specification. SMBJ160A-13-F (Diodes Incorporated) is rated at 2.3A, matching the main part exactly. Both ratings are within acceptable tolerance for this application category.
