Equivalent & Substitute Parts for 3.0SMCJ5.0A-13

Part Overview

The 3.0SMCJ5.0A-13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in surface-mount applications. This zener-type TVS diode operates with a 5V reverse standoff voltage and provides clamping at 9.2V maximum, delivering 326.1A peak pulse current with 3000W peak pulse power dissipation. The device is housed in a DO-214AB (SMC) package and is ROHS3 compliant with unlimited moisture sensitivity rating. Substitute parts are identified to address inventory availability, alternative sourcing requirements, or specific packaging preferences while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the 3.0SMCJ5.0A-13 are classified based on electrical parameter compatibility and package equivalence. The primary substitution criteria are:

Critical Electrical Parameters:

Voltage - Reverse Standoff: 5V (exact match required)
Voltage - Breakdown (Min): 6.4V (exact match required)
Voltage - Clamping (Max) @ Ipp: 9.2V (exact match required)
Unidirectional Channels: 1 (exact match required)
Package / Case: DO-214AB, SMC (exact match required)
Mounting Type: Surface Mount (exact match required)

Allowable Variations:

Current - Peak Pulse (10/1000µs): Substitutes with 163A or 326A are acceptable; 163A represents reduced current capability, while 326A matches the original specification
Power - Peak Pulse: Substitutes with 1500W or 3000W are acceptable; 1500W represents reduced power dissipation, while 3000W matches the original specification
Operating Temperature Range: Substitutes with -55°C to 150°C or -55°C to 175°C are acceptable; extended upper temperature limit does not compromise compatibility
Packaging Format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR) are interchangeable based on procurement requirements

Substitutes with differing clamping voltages (such as 13.4V) or different peak pulse specifications outside the stated ranges are not electrically equivalent and do not qualify as direct substitutes.

Engineering Selection Recommendations

Full Electrical Equivalents (Recommended Primary Substitutes):

SMDJ5.0A (Alpha & Omega Semiconductor Inc.) and SMLJ5.0A-TP (Micro Commercial Co) provide complete electrical equivalence to the 3.0SMCJ5.0A-13, matching all critical voltage parameters, peak pulse current (326A or 326.1A), and power dissipation (3000W). Both are ROHS3 compliant with MSL 1 rating. SMLJ5.0A-TP offers extended operating temperature to 175°C. These parts are suitable for direct substitution without circuit redesign.

Reduced-Performance Substitutes (Lower Current/Power Rating):

SMCJ5.0A (EVVO Semi), SMCJ5.0A-E3/57T (Vishay), SMCJ5.0A-E3/9AT (Vishay), and SMCJ5.0A-TP (Micro Commercial Co) maintain voltage specifications (5V standoff, 6.4V breakdown, 9.2V clamping) but operate at reduced peak pulse current (163A) and power dissipation (1500W). These are suitable only for applications where the lower current and power ratings are acceptable. All are ROHS3 compliant. SMCJ5.0A-TP extends operating temperature to 175°C.

Non-Equivalent Substitute (Not Recommended):

SMCJ5.0A-TR (STMicroelectronics) exhibits a clamping voltage of 13.4V and peak pulse current of 746A (8/20µs), which deviates from the required 9.2V clamping specification. This part is not electrically equivalent and does not qualify as a direct substitute.

Incomplete Specification:

SMCJ5V0A (Fairchild Semiconductor) lacks documented operating temperature range and RoHS compliance status. While voltage and package specifications match, the absence of thermal and compliance data limits its suitability for applications requiring full specification documentation.

Frequently Asked Questions (FAQ)

Q: Can I use SMCJ5.0A (163A rating) in place of 3.0SMCJ5.0A-13 (326.1A rating)?

A: SMCJ5.0A is electrically compatible in terms of voltage parameters but operates at half the peak pulse current and power dissipation. Substitution is permissible only if your circuit design does not require the full 326.1A current handling capability. Review your transient protection requirements before substitution.

Q: What is the difference between SMCJ5.0A-TP and SMLJ5.0A-TP?

A: Both maintain identical voltage specifications (5V standoff, 9.2V clamping). SMCJ5.0A-TP is rated for 163A peak pulse current and 1500W power dissipation, while SMLJ5.0A-TP is rated for 326A peak pulse current and 3000W power dissipation. SMLJ5.0A-TP provides full electrical equivalence to the original part and supports extended operating temperature to 175°C.

Q: Why is SMCJ5.0A-TR not recommended as a substitute?

A: SMCJ5.0A-TR specifies a clamping voltage of 13.4V, which exceeds the required 9.2V maximum. This higher clamping voltage will not provide equivalent transient suppression for circuits designed around the 9.2V specification and is not a direct substitute.

Q: Are packaging format differences (Cut Tape vs. Tape & Reel) significant for substitution?

A: Packaging format differences (Cut Tape, Digi-Reel®, or Tape & Reel) do not affect electrical performance or mechanical compatibility. Selection depends on procurement and assembly requirements. All formats are compatible with standard surface-mount assembly processes.

Q: Does the extended temperature range of SMCJ5.0A-TP (-55°C to 175°C) affect compatibility?

A: No. An extended upper operating temperature limit does not compromise compatibility with circuits designed for the original -55°C to 150°C range. The part remains fully functional within the original temperature specification and offers additional thermal margin for demanding applications.

Q: Is SMCJ5V0A suitable for new designs?

A: SMCJ5V0A meets voltage and package requirements but lacks documented operating temperature range and RoHS compliance certification. For applications requiring full specification traceability and compliance documentation, ROHS3-certified alternatives are preferred.
