SMBJ5.0C-E3/52 Equivalent & Substitute Parts

Part Overview

The SMBJ5.0C-E3/52 is a transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division, designed for general-purpose overvoltage protection in surface-mount applications. This part operates with a 5V reverse standoff voltage and provides 9.6V maximum clamping voltage at peak pulse current of 62.5A, housed in a DO-214AA (SMB) package. The SMBJ5.0C-E3/52 is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the SMBJ5.0C-E3/52 is determined by the following critical parameters:

Voltage - Reverse Standoff: 5V (exact match required)
Voltage - Breakdown (Min): 6.4V (exact match required)
Package / Case: DO-214AA, SMB (exact match required)
Mounting Type: Surface Mount (exact match required)
Type: Zener, Bidirectional (exact match required)
RoHS Status: ROHS3 Compliant (compliance requirement)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Substitute parts must maintain identical electrical performance within the specified voltage and current ratings. Clamping voltage tolerance, peak pulse current capability, and operating temperature range may vary within acceptable engineering margins for the application class. All substitutes must be surface-mount Zener TVS diodes in DO-214AA packaging with equivalent or superior electrical characteristics.

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and MSL 1 (Unlimited) ratings, ensuring long-term availability and environmental regulatory compliance. The SMBJ5.0C-E3/52 is obsolete; direct replacement with an active equivalent is required for new designs and ongoing production.

For applications requiring exact electrical matching to the original specification, the SMBJ5.0CE3/TR13 (Microchip Technology) provides identical clamping voltage (9.6V) and peak pulse current (62.5A) with extended operating temperature range (-65°C to 150°C) and active product status.

For applications where clamping voltage tolerance of ±0.4V is acceptable, the SMBJ5.0CA-E3/52 (Vishay) offers the same manufacturer lineage with active status and equivalent electrical performance. The SMBJ5.0CA (MDD), SMBJ5.0CA-13-F (Diodes Incorporated), SMBJ5.0CA-HR (Littelfuse), SMBJ5.0CA-HRA (Littelfuse), SMBJ5.0CA-TR (STMicroelectronics), and SMBJ5.0CAE3/TR13 (Microchip) all meet the core substitution criteria with clamping voltages of 9.2V and peak pulse currents ranging from 65.2A to 68A.

Frequently Asked Questions (FAQ)

Q: Can I use SMBJ5.0CA-E3/52 as a direct replacement for SMBJ5.0C-E3/52?

A: Yes. Both parts share identical reverse standoff voltage (5V), breakdown voltage (6.4V), and package (DO-214AA, SMB). The clamping voltage differs by 0.4V (9.2V vs. 9.6V), which is within acceptable tolerance for general-purpose TVS applications. SMBJ5.0CA-E3/52 is active and available in higher quantities.

Q: What is the difference between SMBJ5.0CA-HR and SMBJ5.0CA-HRA?

A: Both are Littelfuse products with identical electrical specifications (5V standoff, 9.2V clamping, 65.3A peak pulse). SMBJ5.0CA-HRA is the newer variant with REACH Unaffected status, while SMBJ5.0CA-HR has REACH Affected status. For new designs, SMBJ5.0CA-HRA is preferred.

Q: Does operating temperature range affect substitution compatibility?

A: Operating temperature range does not prevent substitution. The original part operates -55°C to 150°C. Substitutes with extended range (-65°C to 150°C) provide additional margin and are fully compatible. Substitutes with identical or narrower ranges remain compatible if the application does not exceed specified limits.

Q: Are all substitute parts available in the same packaging options?

A: All substitute parts are housed in DO-214AA (SMB) surface-mount packages. Packaging options (Cut Tape, Digi-Reel, Tape & Reel) vary by manufacturer and part number but do not affect electrical compatibility or PCB footprint.

Q: Which substitute offers the highest peak pulse current capability?

A: SMBJ5.0CA-TR (STMicroelectronics) provides 68A peak pulse current, the highest among all listed substitutes. This offers additional margin for transient suppression in high-energy applications.

Q: Is RoHS3 compliance mandatory for substitution?

A: Yes. All listed substitutes maintain ROHS3 compliance, matching the original part's environmental regulatory status. This ensures compatibility with modern manufacturing and end-use requirements.
