Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ13CD-M3/H is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 13V
• Voltage - Clamping (Max) @ Ipp: Within acceptable tolerance range (21.2V ± tolerance)
• Current - Peak Pulse (10/1000µs): Minimum 27.9A
• Package / Case: DO-214AA, SMB (surface mount)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• RoHS Status: ROHS3 Compliant

The SMBJ13CA-E3/52 meets all substitution criteria within the same TransZorb® series, maintaining identical standoff voltage, comparable clamping voltage, and equivalent peak pulse current specifications. Both parts share identical package geometry, thermal operating range, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the SMBJ13CD-M3/H and SMBJ13CA-E3/52 are active production components with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is based on availability and procurement requirements rather than functional differences. The SMBJ13CA-E3/52 demonstrates marginally higher clamping voltage (21.5V vs. 21.2V) and marginally lower peak pulse current (27.9A vs. 28.3A), both within acceptable operating tolerances for general-purpose TVS applications. Both parts maintain identical thermal operating range (-55°C to 150°C junction temperature) and package geometry, ensuring direct mechanical and electrical interchangeability in surface mount designs.

Frequently Asked Questions (FAQ)

Q: Can SMBJ13CA-E3/52 be used as a direct replacement for SMBJ13CD-M3/H?

A: Yes. Both parts share identical reverse standoff voltage (13V), equivalent peak pulse power rating (600W), and identical package geometry (DO-214AA, SMB). The minor differences in clamping voltage (21.5V vs. 21.2V) and peak pulse current (27.9A vs. 28.3A) fall within acceptable substitution tolerances for general-purpose transient voltage suppression applications.

Q: Are there any package or mounting differences between these parts?

A: No. Both SMBJ13CD-M3/H and SMBJ13CA-E3/52 use the DO-214AA (SMB) surface mount package with identical footprint and soldering requirements.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance for design qualification and procurement.

Q: What is the primary difference between these substitute parts?

A: The primary differences are minor variations in clamping voltage specification (21.2V vs. 21.5V) and peak pulse current rating (28.3A vs. 27.9A). These variations are within normal manufacturing tolerances for the SMBJ13 base product number and do not affect functional interchangeability in circuit applications.

Q: Are both parts currently in active production?

A: Yes. Both SMBJ13CD-M3/H and SMBJ13CA-E3/52 maintain active product status with current inventory availability from Vishay General Semiconductor - Diodes Division.
