SMBJ58A-13 Equivalent & Substitute Parts

Part Overview

The SMBJ58A-13 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in surface-mount applications. This part operates with a 58V reverse standoff voltage and provides 93.6V maximum clamping voltage at peak pulse current. The SMBJ58A-13 is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SMBJ58A-13 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 58V
• Voltage - Breakdown (Min): 64.4V
• Voltage - Clamping (Max) @ Ipp: 93.6V
• Current - Peak Pulse (10/1000µs): 6.4A (±tolerance acceptable)
• Power - Peak Pulse: 600W
• Type: Zener, Unidirectional
• Mounting Type: Surface Mount
• Package / Case: DO-214AA (SMB)
• Operating Temperature Range: -55°C ~ 150°C minimum

Substitute parts are grouped into two categories:

Direct Electrical Equivalents (Same Package): Parts maintaining identical electrical specifications and DO-214AA (SMB) packaging. These provide pin-for-pin and functional compatibility without PCB layout modifications.

Functional Equivalents (Alternative Package): Parts meeting all electrical specifications but using alternative surface-mount packages (SOD-128). These require PCB footprint verification before implementation.

Near-Equivalent Alternatives: Parts with minor deviations in peak pulse current or clamping voltage within acceptable engineering tolerance for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents):

SMBJ58A-13-F (Diodes Incorporated) and SMBJ58A-TR (STMicroelectronics) are the preferred direct replacements. Both maintain identical electrical specifications, DO-214AA (SMB) packaging, and are currently in active production status. SMBJ58A-13-F offers the advantage of being from the original manufacturer with higher inventory availability (17,100 pcs). SMBJ58A-TR provides an alternative from a major semiconductor supplier with substantial stock (47,794 pcs) and is available in Cut Tape & Digi-Reel packaging.

Secondary Substitutes (Electrical Equivalents):

SMBJ58A (Meritek) matches all electrical parameters with identical 58V standoff voltage, 93.6V clamping voltage, and 6.41A peak pulse current. This part is actively produced with good inventory (17,400 pcs) and maintains the same DO-214AA (SMB) package footprint.

Alternative Package Option:

PTVS58VP1UP,115 (Nexperia USA Inc.) provides identical electrical specifications but uses SOD-128 packaging instead of DO-214AA (SMB). This part includes AEC-Q101 automotive qualification and is suitable for applications requiring automotive-grade components. PCB footprint redesign is required for implementation.

Near-Equivalent Alternative:

SMBJ54CA-TP (Micro Commercial Co) operates at a lower reverse standoff voltage (54V) with reduced clamping voltage (87.1V). This part is suitable only for applications where the lower voltage rating is acceptable and provides extended operating temperature range (-55°C ~ 175°C). Note: This part is bidirectional, whereas the main part is unidirectional.

Frequently Asked Questions (FAQ)

Q: Can SMBJ58A-13-F be used as a direct replacement for SMBJ58A-13?

A: Yes. SMBJ58A-13-F is a direct pin-for-pin and functional equivalent. Both parts share identical electrical specifications (58V standoff, 93.6V clamping, 6.4A peak pulse), the same DO-214AA (SMB) package, and equivalent operating temperature range. No PCB modifications are required.

Q: What is the difference between SMBJ58A-13 and SMBJ58A-TR?

A: Both parts are electrically identical with 58V standoff voltage and 93.6V clamping voltage. The primary difference is the manufacturer (Diodes Incorporated vs. STMicroelectronics) and packaging format. SMBJ58A-TR is available in Cut Tape & Digi-Reel format with higher inventory availability.

Q: Why is SMBJ54CA-TP listed as a substitute if it has different voltage ratings?

A: SMBJ54CA-TP is included as a near-equivalent alternative for applications where the lower voltage rating (54V standoff, 87.1V clamping) is acceptable. It maintains the same 600W power rating and DO-214AA (SMB) package. This part is suitable only for circuits designed to operate at lower voltage thresholds.

Q: Can PTVS58VP1UP,115 replace SMBJ58A-13 without PCB changes?

A: No. PTVS58VP1UP,115 uses SOD-128 packaging, whereas SMBJ58A-13 uses DO-214AA (SMB) packaging. While electrically equivalent, the different package footprint requires PCB redesign. This part is recommended only when automotive-grade qualification (AEC-Q101) is a design requirement.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed (SMBJ58A-13-F, SMBJ58A-TR, SMBJ58A, PTVS58VP1UP,115, and SMBJ54CA-TP) are ROHS3 compliant. The original SMBJ58A-13 is RoHS non-compliant. If RoHS compliance is required, substitute parts must be selected from the active production alternatives.

Q: What is the inventory status of these substitute parts?

A: SMBJ58A-TR has the highest inventory (47,794 pcs), followed by SMBJ58A (Meritek) at 17,400 pcs and SMBJ58A-13-F at 17,100 pcs. PTVS58VP1UP,115 has 64,145 pcs available. SMBJ54CA-TP has lower availability at 1,867 pcs.

Q: Can bidirectional TVS diodes like SMBJ54CA-TP be used in place of unidirectional parts?

A: Bidirectional TVS diodes provide protection in both directions and can function in unidirectional applications, but they introduce additional capacitance and may not be optimal for single-direction protection circuits. SMBJ54CA-TP is bidirectional, whereas the main part and most substitutes are unidirectional. Verify circuit requirements before substitution.
