SMCJ5.0CA-M3/9AT Transient Voltage Suppressor Diode - Equivalent & Substitute Parts

Part Overview

The SMCJ5.0CA-M3/9AT is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the DO-214AB (SMC) package and provides transient overvoltage protection for general-purpose applications. The device features a 5V reverse standoff voltage with a 9.2V maximum clamping voltage and 163A peak pulse current capability. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, substitute parts are identified to support procurement flexibility, inventory optimization, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMCJ5.0CA-M3/9AT are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Breakdown (Min): 6.4V
• Voltage - Clamping (Max) @ Ipp: 9.2V
• Current - Peak Pulse (10/1000µs): 163A (or higher)
• Power - Peak Pulse: 1500W
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Type: Zener, Bidirectional (1 channel)
• Operating Temperature: -55°C to 150°C (TJ)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts maintain identical electrical performance specifications and package compatibility. Packaging format variations (Tape & Reel, Cut Tape, Digi-Reel) do not affect functional equivalence and are selected based on procurement and assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance. Selection among equivalent parts should be based on:

Packaging Format Availability: SMCJ5.0CA-E3/57T (Cut Tape) and SMCJ5.0CA (Cut Tape & Digi-Reel) support high-volume automated assembly. SMCJ5.0CA-M3/9AT, SMCJ5.0CA-13-F, and SMCJ5V0CA (Tape & Reel) accommodate standard reel-based pick-and-place operations.

Peak Pulse Current Performance: SMCJ5.0CA (Taiwan Semiconductor Corporation) provides 171A peak pulse current, exceeding the 163A specification of the primary part. This represents enhanced transient suppression capability within the same voltage and power envelope.

Manufacturer Availability: Multiple manufacturers (Vishay, Taiwan Semiconductor Corporation, Diodes Incorporated, STMicroelectronics) ensure supply chain redundancy and procurement flexibility.

Clamping Voltage Consideration: SMCJ5.0CA-TR (STMicroelectronics) exhibits a 13.4V maximum clamping voltage with significantly higher peak pulse current (746A at 8/20µs pulse width). This part operates at the same reverse standoff voltage but provides enhanced transient protection. Selection of this variant requires confirmation that the higher clamping voltage is acceptable for the protected circuit.

Frequently Asked Questions (FAQ)

Q: Can SMCJ5.0CA-E3/57T replace SMCJ5.0CA-M3/9AT in production?

A: Yes. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical specifications (5V standoff, 9.2V clamping, 163A peak pulse). The difference is packaging format: SMCJ5.0CA-E3/57T uses Cut Tape while SMCJ5.0CA-M3/9AT uses Tape & Reel. Verify your assembly equipment compatibility with the selected packaging format.

Q: What is the difference between SMCJ5.0CA (Taiwan Semiconductor Corporation) and the Vishay part?

A: The Taiwan Semiconductor Corporation variant delivers 171A peak pulse current compared to 163A for the Vishay part. All other electrical parameters (voltage ratings, power dissipation, temperature range) are identical. The higher current rating provides additional transient suppression margin within the same package and power envelope.

Q: Is SMCJ5.0CA-TR a direct substitute?

A: SMCJ5.0CA-TR (STMicroelectronics) maintains the same 5V reverse standoff voltage and 1500W peak pulse power. However, it specifies a 13.4V maximum clamping voltage and 746A peak pulse current at 8/20µs pulse width, compared to 9.2V and 163A for the primary part. This part provides enhanced transient protection but operates at a higher clamping voltage. Substitution requires circuit-level verification that the higher clamping voltage does not exceed protected component voltage ratings.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification and Moisture Sensitivity Level 1 (Unlimited), matching the environmental and regulatory status of SMCJ5.0CA-M3/9AT.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® formats are packaging and delivery methods only. Electrical specifications remain identical across all format variants of the same part number. Selection is based on assembly process requirements and inventory management practices.

Q: Can I use SMCJ5V0CA as a substitute?

A: Yes. SMCJ5V0CA (Taiwan Semiconductor Corporation) provides identical electrical specifications to SMCJ5.0CA-M3/9AT: 5V standoff, 9.2V clamping, 163A peak pulse, and 1500W power dissipation. The part number variation reflects manufacturer nomenclature but does not indicate functional differences. Both are surface mount, DO-214AB package, ROHS3 compliant, and MSL 1.
