SMBJ64CA-13 Equivalent & Substitute Parts
Part Overview
The SMBJ64CA-13 is a Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in surface-mount applications. This part operates with a 64V reverse standoff voltage and provides 103V maximum clamping voltage at peak pulse current. The SMBJ64CA-13 is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for circuit protection applications.

Substitute Part Grouping Explanation
Substitution eligibility for the SMBJ64CA-13 is determined by the following critical parameters:
- Voltage - Reverse Standoff (Typ): 64V
- Voltage - Clamping (Max) @ Ipp: 103V
- Current - Peak Pulse (10/1000µs): 5.8A (±tolerance acceptable)
- Power - Peak Pulse: 600W
- Package / Case: DO-214AA, SMB
- Mounting Type: Surface Mount

Substitute parts are grouped into two categories:
Category A - Direct Electrical Equivalents: Parts with identical voltage ratings (64V standoff, 103V clamping) and matching peak pulse current specifications. These parts maintain full functional compatibility with the original circuit design.
Category B - Manufacturer Recommended Alternatives: Parts designated as manufacturer-recommended substitutes that meet the core electrical parameters but may have minor variations in clamping voltage or peak pulse current within acceptable engineering tolerances.

Engineering Selection Recommendations
Primary Substitutes (Full Compatibility)
SMBJ64CA-13-F (Diodes Incorporated) is the direct replacement. It maintains identical electrical specifications and package configuration while offering active product status and ROHS3 compliance, addressing the discontinuation of the original part.
SMBJ64CAE3/TR13 (Microchip Technology) provides equivalent electrical performance with active status and ROHS3 compliance. This part is designated as a manufacturer-recommended alternative.
Secondary Substitutes (Electrical Equivalence with Minor Variations)
SMBJ64CA (Meritek) and TV06B640JB-G (Comchip Technology) maintain the 64V standoff and 103V clamping specifications with peak pulse current of 5.83A, representing a 0.43A increase from the original 5.8A specification. Both parts are active and ROHS3 compliant.
SMBJ64CA-TP (Micro Commercial Co) provides identical electrical specifications to the original part with active status and ROHS3 compliance.
Limited Compatibility Substitute
SMBJ58CE3/TR13 (Microchip Technology) operates at a reduced 58V reverse standoff voltage with 103V clamping. This part is suitable only for applications where the lower standoff voltage is acceptable within circuit design margins.
SMBJ64CE3/TR13 (Microchip Technology) features an elevated 114V clamping voltage with reduced peak pulse current of 5.3A. This part is suitable only for applications requiring higher clamping voltage protection.
Frequently Asked Questions (FAQ)
Q: Can SMBJ64CA-13-F be used as a direct replacement for SMBJ64CA-13?
A: Yes. SMBJ64CA-13-F is manufactured by the same company (Diodes Incorporated) and maintains identical electrical specifications: 64V reverse standoff, 103V clamping voltage, and 5.8A peak pulse current. The primary difference is product status (active vs. discontinued) and RoHS compliance (ROHS3 vs. non-compliant). Both use the DO-214AA (SMB) package.
Q: What is the difference between SMBJ64CA-13 and SMBJ64CA?
A: The SMBJ64CA-13 is manufactured by Diodes Incorporated, while SMBJ64CA is available from multiple manufacturers including Meritek. Electrical specifications are equivalent (64V standoff, 103V clamping). The primary differences are manufacturer, product status, and RoHS compliance. SMBJ64CA from Meritek shows peak pulse current of 5.83A versus 5.8A for the original part, a negligible difference within typical component tolerances.
Q: Can SMBJ58CE3/TR13 replace SMBJ64CA-13?
A: SMBJ58CE3/TR13 has a lower reverse standoff voltage of 58V compared to the original 64V specification. This part is suitable only if circuit design margins accommodate the reduced standoff voltage. The clamping voltage (103V) and peak pulse current (5.8A) remain equivalent.
Q: What does the packaging designation "Tape & Reel (TR)" mean?
A: Tape & Reel (TR) indicates the component is supplied on continuous tape wound on a reel, suitable for automated assembly processes. This is a supply format difference only and does not affect electrical performance or circuit compatibility.
Q: Are all substitute parts RoHS3 compliant?
A: All substitute parts listed are ROHS3 compliant except the original SMBJ64CA-13, which is RoHS non-compliant. If RoHS compliance is a requirement for your application, any of the listed substitutes meet this criterion.
Q: What is the significance of the "-13" suffix in SMBJ64CA-13?
A: The "-13" suffix typically indicates a specific packaging or tape configuration variant. SMBJ64CA-13-F includes the "-F" designation, indicating a different packaging format (Cut Tape & Digi-Reel). The electrical specifications remain identical between these variants.
Q: Can SMBJ64CE3/TR13 be used instead of SMBJ64CA-13?
A: SMBJ64CE3/TR13 has a higher clamping voltage (114V vs. 103V) and lower peak pulse current (5.3A vs. 5.8A). This part is suitable only for applications where the elevated clamping voltage provides acceptable protection margins and the reduced current rating does not exceed circuit requirements.
