SMBJ12A/TR13 Equivalent & Substitute Parts

Part Overview

The SMBJ12A/TR13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by YAGEO, designed for general-purpose overvoltage protection applications. This surface-mount component operates in the 12V reverse standoff voltage range with a maximum clamping voltage of 19.9V and peak pulse current rating of 30.2A. The part is actively produced and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Equivalent substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ12A/TR13 are qualified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires exact matching of the following parameters:

• Voltage - Reverse Standoff (Typ): 12V
• Voltage - Breakdown (Min): 13.3V
• Voltage - Clamping (Max) @ Ipp: 19.9V
• Current - Peak Pulse (10/1000µs): 30.2A
• Power - Peak Pulse: 600W
• Operating Temperature Range: -55°C to 150°C
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Type: Zener
• Unidirectional Channels: 1

Only components meeting all these criteria are classified as direct equivalents. The P6SMBJ12AS_R1_00001 from Panjit International Inc. satisfies all substitution requirements and is therefore qualified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ12A/TR13 and P6SMBJ12AS_R1_00001 are active production components with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Selection between these parts should be based on:

Availability and Lead Time: The SMBJ12A/TR13 maintains 2,669 pieces in current inventory, while the P6SMBJ12AS_R1_00001 has 1,267 pieces available. Choose based on procurement timeline and supply chain requirements.

Manufacturer Preference: YAGEO and Panjit International Inc. are both established manufacturers of transient voltage suppressor components. Selection may depend on existing supplier relationships, quality agreements, or preferred vendor lists within your organization.

Packaging and Logistics: Both parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes. No differences exist in handling, storage, or assembly requirements.

Compliance Requirements: Both components meet ROHS3 compliance and carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, ensuring equivalent regulatory and export compliance status.

Frequently Asked Questions (FAQ)

Q: Can the P6SMBJ12AS_R1_00001 be used as a direct replacement for the SMBJ12A/TR13 in existing designs?

A: Yes. The P6SMBJ12AS_R1_00001 is a direct electrical and mechanical equivalent. All critical parameters including voltage ratings, current ratings, temperature range, and package type are identical. No circuit modifications or PCB layout changes are required.

Q: Are there any differences in the DO-214AA package between these two parts?

A: No. Both parts use the identical DO-214AA (SMB) surface-mount package. Pin configuration, footprint, and mechanical dimensions are equivalent, allowing direct substitution on the same PCB.

Q: What is the significance of the 12V reverse standoff voltage rating?

A: The 12V reverse standoff voltage indicates the maximum voltage the diode can withstand in its normal operating state without conducting. This parameter determines the circuit voltage level at which the TVS diode begins protection. Both parts maintain this specification identically.

Q: How do the clamping voltage and peak pulse current ratings affect component selection?

A: The 19.9V maximum clamping voltage and 30.2A peak pulse current define the protection characteristics during transient events. These ratings must match the circuit requirements exactly. Both parts provide identical protection performance for applications designed around these specifications.

Q: Is the operating temperature range suitable for automotive or industrial applications?

A: The -55°C to 150°C operating temperature range supports both automotive and industrial environments. Both the SMBJ12A/TR13 and P6SMBJ12AS_R1_00001 maintain this identical range, ensuring equivalent thermal performance across application categories.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean for storage and handling?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this rating, eliminating the need for dry-pack storage or baking procedures prior to assembly.

Q: Are there any differences in RoHS compliance between these parts?

A: No. Both components are ROHS3 compliant with identical regulatory status. They meet all restrictions on hazardous substances and are suitable for applications requiring RoHS certification.
