SMBJ36CA-13 Transient Voltage Suppressor (TVS) Diode Equivalent & Substitute Parts

Part Overview

The SMBJ36CA-13 is a bidirectional Zener transient voltage suppressor diode manufactured by Diodes Incorporated in the SMB (DO-214AA) surface mount package. This component is designed for general-purpose transient voltage suppression applications with a 36V reverse standoff voltage and 58.1V maximum clamping voltage. The part is currently discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMBJ36CA-13 is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 36V
• Voltage - Breakdown (Min): 40V
• Voltage - Clamping (Max) @ Ipp: 58.1V
• Current - Peak Pulse (10/1000µs): 10.3A minimum
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Bidirectional Channels: 1

Substitute parts are grouped into two categories:

Direct Electrical Equivalents: Parts with identical or compatible voltage ratings, clamping characteristics, and peak pulse current specifications that maintain the same functional performance in the circuit.

Manufacturer Alternatives: Parts from different manufacturers (MDD, Micro Commercial Co, STMicroelectronics) that meet the same electrical specifications and package requirements, enabling cross-manufacturer sourcing.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Direct Replacement): SMBJ36CA-13-F (Diodes Incorporated) is the recommended direct substitute. It maintains identical electrical specifications (36V standoff, 58.1V clamping, 10.3A peak pulse) and package configuration while offering active product status and ROHS3 compliance. This part is available in high inventory (125,400 pcs) with Cut Tape and Digi-Reel packaging options.

Alternative Equivalents: SMBJ36CA-TR (STMicroelectronics) and SMBJ36CA-TP (Micro Commercial Co) provide equivalent electrical performance with active status and ROHS3 compliance. SMBJ36CA-TP extends the operating temperature range to -55°C ~ 175°C, suitable for applications requiring higher temperature performance.

Cross-Manufacturer Option: SMBJ36CA (MDD) is electrically compatible with a marginally higher peak pulse current specification (10.4A vs. 10.3A) and operates within -50°C ~ 150°C. This part is available in substantial inventory (16,921 pcs).

Non-Equivalent Alternative: SM6T42CAY (STMicroelectronics) differs in clamping voltage (76V vs. 58.1V) and peak pulse current (52A at 8/20µs vs. 10.3A at 10/1000µs). This part is not a direct substitute and is suitable only for applications requiring higher transient energy absorption or different voltage clamping characteristics. It includes AEC-Q101 automotive qualification.

Compliance Consideration: The original SMBJ36CA-13 is RoHS non-compliant. All active substitute parts listed are ROHS3 compliant, making them suitable for new designs and applications with RoHS requirements.

Frequently Asked Questions (FAQ)

Q: Can SMBJ36CA-13-F directly replace SMBJ36CA-13 in existing designs?

A: Yes. SMBJ36CA-13-F maintains identical electrical specifications (36V standoff, 58.1V clamping, 10.3A peak pulse) and the same DO-214AA SMB package. The primary difference is product status (active vs. discontinued) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between SMBJ36CA-13-F and SMBJ36CA-TR?

A: Both parts are electrically equivalent with identical voltage ratings and peak pulse current. SMBJ36CA-13-F is manufactured by Diodes Incorporated, while SMBJ36CA-TR is manufactured by STMicroelectronics. Both are available in Cut Tape and Digi-Reel packaging and are ROHS3 compliant.

Q: Is SM6T42CAY a suitable substitute?

A: SM6T42CAY is not a direct substitute. While it shares the same 36V standoff voltage and DO-214AA package, it specifies a higher clamping voltage (76V vs. 58.1V) and significantly higher peak pulse current (52A at 8/20µs vs. 10.3A at 10/1000µs). Use this part only if your application requires higher transient energy suppression or different voltage clamping characteristics.

Q: Does the MDD SMBJ36CA meet the same specifications?

A: The MDD SMBJ36CA is electrically compatible with a peak pulse current of 10.4A (compared to 10.3A) and operates within -50°C ~ 150°C (compared to -55°C ~ 150°C for the original part). The 0.1A difference in peak pulse current is within typical manufacturing tolerance and does not affect functional equivalence for general-purpose transient suppression applications.

Q: What packaging options are available for substitutes?

A: SMBJ36CA-13-F and SMBJ36CA-TR are available in Cut Tape (CT) and Digi-Reel packaging. SMBJ36CA-TP is available in Tape & Reel (TR) format. MDD SMBJ36CA packaging information is not specified. All parts use the DO-214AA SMB surface mount package.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed (SMBJ36CA-13-F, SMBJ36CA, SMBJ36CA-TP, SM6T42CAY, SMBJ36CA-TR) are ROHS3 compliant. The original SMBJ36CA-13 is RoHS non-compliant.
