P6SMBJ13A Equivalent & Substitute Parts

Part Overview

The P6SMBJ13A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage protection in surface-mount applications. The device features a 13V reverse standoff voltage rating with an 18.2V maximum clamping voltage and 600W peak pulse power dissipation capability in a DO-214AA (SMB) package.

The P6SMBJ13A is classified as obsolete. Equivalent and substitute parts are available from multiple manufacturers with matching or compatible electrical and mechanical specifications, enabling continued circuit protection functionality in new designs and production runs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMBJ13A are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 11.0V to 11.1V
• Voltage - Clamping (Max) @ Ipp: 18.2V
• Current - Peak Pulse (10/1000µs): 33A to 34.6A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA or SMB
• Mounting Type: Surface Mount
• Type: Zener, Unidirectional

All substitute parts listed maintain these core electrical specifications within the allowed tolerance range, ensuring functional equivalence in transient voltage suppression applications. Package compatibility (DO-214AA/SMB) and surface-mount configuration are preserved across all substitutes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Identical Specifications):

• P6SMB13A (Eaton): Direct electrical equivalent with active product status. Identical voltage and current ratings. Suitable for standard applications requiring -55°C to 150°C operating range.
• TPSMB13A (Littelfuse): Same manufacturer as original part. Identical electrical specifications with extended operating temperature range (-65°C to 175°C) and AEC-Q101 automotive qualification. Recommended for applications requiring enhanced temperature performance or automotive-grade reliability.

Secondary Substitutes (Minor Parameter Variations):

• P6SMB13A-E3/52 and P6SMB13A-E3/5B (Vishay): Peak pulse current rated at 33A versus 34.6A on original part. Extended lower operating temperature limit (-65°C). Functionally equivalent for general-purpose transient suppression. Tape & Reel packaging available.
• SMBJ11A (Meritek): Reverse standoff voltage 11.0V (0.1V lower than original). Peak pulse current 32.97A. Maintains 18.2V clamping voltage and 600W power rating. Suitable for applications with 11V nominal standoff requirement.
• SMBJ11AE3/TR13 (Microchip Technology): Reverse standoff voltage 11.0V. Peak pulse current 33A. Extended lower operating temperature (-65°C). Active product status with ROHS3 compliance.

All substitutes maintain DO-214AA (SMB) package compatibility and surface-mount configuration. Selection should prioritize active product status and compliance certifications matching application requirements.

Frequently Asked Questions (FAQ)

Q: Can P6SMB13A (Eaton) directly replace P6SMBJ13A (Littelfuse)? A: Yes. Both parts share identical electrical specifications: 11.1V reverse standoff voltage, 18.2V clamping voltage, 34.6A peak pulse current, and 600W power dissipation. Package and mounting type are identical (DO-214AA SMB, surface mount). The primary difference is manufacturer and product status (Eaton part is active).

Q: What is the difference between TPSMB13A and P6SMBJ13A? A: Electrical specifications are identical. TPSMB13A offers extended operating temperature range (-65°C to 175°C versus -55°C to 150°C) and includes AEC-Q101 automotive qualification. Both are manufactured by Littelfuse. TPSMB13A is the active product line replacement.

Q: Why do some substitutes show 33A instead of 34.6A peak pulse current? A: Vishay P6SMB13A-E3/52 and P6SMB13A-E3/5B are rated at 33A peak pulse current, which is within the functional tolerance for transient suppression applications. The 0.5A difference does not affect circuit protection capability at the specified 18.2V clamping voltage and 600W power level.

Q: Are SMBJ11A and SMBJ11AE3/TR13 suitable replacements? A: Both parts are functionally equivalent with 11.0V reverse standoff voltage (0.1V lower than original) and maintain the critical 18.2V clamping voltage specification. They are suitable for applications where the 11V standoff threshold is acceptable. Peak pulse current is 32.97A to 33A, within functional tolerance.

Q: Does package type affect substitution compatibility? A: All listed substitutes use DO-214AA (SMB) surface-mount package, ensuring mechanical and electrical compatibility with P6SMBJ13A footprints. Packaging format (Tape & Reel versus bulk) does not affect electrical performance or board-level compatibility.

Q: Which substitute offers the best temperature performance? A: TPSMB13A provides the widest operating temperature range (-65°C to 175°C) and includes AEC-Q101 automotive qualification, making it suitable for high-temperature or automotive applications requiring enhanced reliability.
