SMBJ6.0CA Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The SMBJ6.0CA is a surface mount transient voltage suppressor diode manufactured by Vishay General Semiconductor - Diodes Division, designed for general purpose overvoltage protection applications. This component operates with a 6V reverse standoff voltage and provides 10.3V maximum clamping voltage at peak pulse current. The original part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ6.0CA is determined by strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

Voltage - Reverse Standoff: 6V (exact match required)
Voltage - Breakdown (Min): 6.67V minimum
Voltage - Clamping (Max) @ Ipp: 10.3V maximum
Current - Peak Pulse (10/1000µs): 58.3A nominal (±5% tolerance acceptable)
Power - Peak Pulse: 600W
Package / Case: DO-214AA or SMB equivalent
Mounting Type: Surface Mount
Type: Zener diode, bidirectional, single channel

Parts are grouped into two categories: direct electrical equivalents (matching all primary criteria) and functional alternatives (meeting core voltage and current specifications with minor parameter variations).

Engineering Selection Recommendations

Direct Electrical Equivalents (Preferred for Drop-In Replacement):

SMBJ6.0CA-13-F (Diodes Incorporated), SMBJ6V0CA (Taiwan Semiconductor Corporation), SMBJ6.0CAE3/TR13 (Microchip Technology), and SMBJ6.0CA (EVVO Semi) provide complete electrical equivalence with identical voltage and current specifications. All are active products with ROHS3 compliance, addressing the obsolescence and compliance limitations of the original Vishay part.

Near-Equivalent Alternatives (Minor Parameter Variance):

TV06B6V0JB-G and TV06B6V0JB-HF (Comchip Technology) match all critical voltage parameters with peak pulse current of 58.25A, representing a 0.09% deviation from the 58.3A specification. Both are active, ROHS3 compliant products in DO-214AA packaging.

SMBJ6.0CA-TR (STMicroelectronics) provides 61A peak pulse current (4.6% above specification) with 6.7V breakdown voltage (0.45% above minimum). This part remains within functional tolerance for general purpose applications.

Limited Compatibility Alternative:

SM6T6V8CA (STMicroelectronics) operates at 5.8V reverse standoff with 13.4V clamping voltage and 298A peak pulse current. This part is suitable only for applications where higher current handling and clamping voltage are acceptable design parameters.

SMBJ6.0CE3/TR13 (Microchip Technology) exhibits 11.4V clamping voltage and 52.6A peak pulse current, representing deviations from the original specification suitable only for applications with relaxed clamping voltage requirements.

Compliance and Availability:

All recommended substitutes are active products with ROHS3 compliance, eliminating the non-compliance status of the obsolete original part. Inventory availability ranges from 840 to 95,300 units across substitute options.

Frequently Asked Questions (FAQ)

Q: Can SMBJ6.0CA-13-F directly replace SMBJ6.0CA in existing designs?

A: Yes. SMBJ6.0CA-13-F matches all electrical specifications (6V standoff, 10.3V clamping, 58.3A peak pulse) and package requirements (DO-214AA SMB). The primary difference is manufacturer (Diodes Incorporated vs. Vishay) and ROHS3 compliance status. Tape & Reel packaging is standard for production quantities.

Q: What is the difference between SMBJ6V0CA and SMBJ6.0CA?

A: Both parts are electrically identical with 6V standoff voltage, 10.3V clamping, and 58.3A peak pulse current. The designation difference reflects manufacturer nomenclature (Taiwan Semiconductor Corporation vs. Vishay). Both are surface mount DO-214AA packages suitable for direct substitution.

Q: Are Comchip TV06B6V0JB-G and TV06B6V0JB-HF interchangeable?

A: Yes, both Comchip parts are electrically identical with 6V standoff, 10.3V clamping, and 58.25A peak pulse current in DO-214AA packaging. The suffix difference (-G vs. -HF) indicates packaging or lead finish variations. Both are active, ROHS3 compliant products.

Q: When should SM6T6V8CA be considered instead of direct equivalents?

A: SM6T6V8CA operates at 5.8V standoff with 13.4V clamping and 298A peak pulse current. This part is suitable only for applications where higher transient current absorption and elevated clamping voltage are design requirements. It is not a direct replacement for standard 6V/10.3V specifications.

Q: What does ROHS3 compliance mean for this product category?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All active substitute parts listed are ROHS3 compliant, addressing environmental and regulatory requirements not met by the obsolete original part.

Q: Are there packaging differences between substitute parts?

A: All substitute parts use DO-214AA or SMB package designations, which are mechanically and electrically equivalent. Packaging options include Cut Tape (CT), Tape & Reel (TR), and Digi-Reel formats. Selection depends on procurement volume and assembly requirements rather than electrical performance.

Q: How do peak pulse current specifications affect circuit performance?

A: Peak pulse current (10/1000µs) defines the maximum transient current the diode can absorb without damage. Specifications range from 52.6A to 298A across available substitutes. Applications requiring standard 6V/10.3V protection use 58.3A-rated parts; higher current applications require SM6T6V8CA or equivalent high-current alternatives.

Q: Can SMBJ6.0CE3/TR13 be used in place of SMBJ6.0CA?

A: SMBJ6.0CE3/TR13 has 11.4V clamping voltage and 52.6A peak pulse current, both deviating from the original 10.3V/58.3A specification. This part is suitable only for applications where higher clamping voltage and lower current handling are acceptable design parameters.
