SMCJ64CA-13 Equivalent & Substitute Parts

Part Overview

The SMCJ64CA-13 is a transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 64V reverse standoff voltage, 103V clamping voltage, and 1500W peak pulse power rating in a DO-214AB (SMC) package. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers to maintain design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMCJ64CA-13 is determined by strict equivalence in the following critical parameters:

• Voltage - Reverse Standoff (Typ): 64V ± tolerance
• Voltage - Breakdown (Min): 71.1V minimum
• Voltage - Clamping (Max) @ Ipp: 103V maximum
• Package / Case: DO-214AB (SMC) surface mount
• Type: Zener, bidirectional, single channel
• Mounting: Surface mount configuration

Substitute parts are grouped into two categories:

Direct Equivalents (1500W class): Parts with identical peak pulse power rating (1500W) and peak pulse current of 14.6A ± tolerance. These provide pin-for-pin and functional replacement without circuit redesign.

Higher-Power Alternatives (3000W and 5000W classes): Parts with identical voltage parameters but elevated peak pulse power ratings (3000W or 5000W) and correspondingly higher peak pulse currents. These are backward-compatible for applications where the original 1500W rating provides design margin, as they maintain the same voltage protection characteristics while offering enhanced transient energy absorption capability.

Parameter Comparison

Engineering Selection Recommendations

Primary Direct Equivalent: SMCJ64CA-TP (Micro Commercial Co) is the preferred substitute. It maintains identical voltage and power specifications to the SMCJ64CA-13, offers an extended operating temperature range (-55°C ~ 175°C), is ROHS3 compliant, and is currently in active production with adequate inventory (2816 pcs).

Secondary Direct Equivalent: SMCJ64CA (Meritek) provides functional equivalence with 1500W power rating and active product status. Peak pulse current specification (14.56A) is within tolerance of the original 14.6A rating. ROHS3 compliant with substantial inventory availability (9881 pcs).

Tertiary Direct Equivalent: 1.5SMC75CA (Taiwan Semiconductor Corporation) meets voltage specifications within tolerance (64.1V standoff, 71.3V breakdown) and maintains 1500W power rating. Suitable for applications where the slight voltage variation is acceptable. ROHS3 compliant with highest inventory level (36900 pcs).

Higher-Power Alternatives: SMDJ64CA-T7 (Littelfuse), SMDJ64CA (Alpha & Omega), 5.0SMDJ64CA-T7 (Littelfuse), and 5.0SMDJ64CA (MDE) are backward-compatible substitutes offering 3000W or 5000W peak pulse power. These are suitable for designs where increased transient energy absorption is beneficial or where circuit margins permit higher power dissipation. All are ROHS3 compliant and in active production.

All substitute parts are ROHS3 compliant, addressing the non-compliance status of the discontinued original part.

Frequently Asked Questions (FAQ)

Q: Can SMCJ64CA-TP be used as a direct replacement for SMCJ64CA-13?

A: Yes. SMCJ64CA-TP is a direct functional equivalent with identical voltage parameters (64V standoff, 71.1V breakdown, 103V clamping) and power rating (1500W). It is pin-compatible in DO-214AB (SMC) package and requires no circuit modification.

Q: What is the difference between 1500W and 3000W TVS diodes in this voltage class?

A: The 1500W and 3000W variants maintain identical voltage protection characteristics (64V standoff, 103V clamping). The difference is peak pulse current handling capacity: 1500W class handles approximately 14.6A, while 3000W class handles approximately 29A. Selection depends on the transient energy levels in the protected circuit. Higher-power variants provide additional margin for severe transient events.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant. The original SMCJ64CA-13 is RoHS non-compliant; substitution with any listed alternative addresses this compliance requirement.

Q: Can I use a 5000W variant instead of the 1500W original?

A: Yes. The 5.0SMDJ64CA and 5.0SMDJ64CA-T7 maintain identical voltage specifications and are backward-compatible. They provide enhanced transient energy absorption capability. No circuit modification is required; the higher power rating represents additional design margin.

Q: What is the temperature operating range difference between substitutes?

A: Most substitutes operate at -55°C ~ 150°C, matching the original. SMCJ64CA-TP extends to -55°C ~ 175°C, and SMDJ64CA-T7 and 5.0SMDJ64CA-T7 extend to -65°C ~ 150°C. Select based on application temperature requirements.

Q: Are there packaging differences between substitute parts?

A: All substitute parts use DO-214AB (SMC) surface-mount package, identical to the original SMCJ64CA-13. SMCJ64CA-TP is supplied in Tape & Reel (TR) packaging; others vary. Verify packaging format with supplier for assembly compatibility.

Q: What inventory levels are available for each substitute?

A: SMCJ64CA-TP: 2816 pcs; SMCJ64CA (Meritek): 9881 pcs; 1.5SMC75CA: 36900 pcs; SMDJ64CA-T7: 754 pcs; 5.0SMDJ64CA-T7: 1627 pcs; 5.0SMDJ64CA: 21300 pcs; SMDJ64CA: 101300 pcs. Verify current availability with supplier.
