SMBJ36CA-M3/5B Equivalent & Substitute Parts

Part Overview

The SMBJ36CA-M3/5B is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 36V reverse standoff category and is designed for general-purpose transient voltage protection applications. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the DO-214AA (SMB) package family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ36CA-M3/5B are classified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

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

Parts are grouped into three categories: direct equivalents (identical electrical specifications), manufacturer-recommended alternatives (functionally equivalent with minor parameter variations), and compatible substitutes (same voltage class and package with acceptable parameter deviations).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. Selection between equivalents should be based on packaging availability and supply chain requirements rather than electrical performance, as all parts meet the core 36V/58.1V/10.3A specifications.

SMBJ36CA-E3/52 and SMBJ36CA-E3/5B from Vishay are direct electrical equivalents with identical specifications to the main part. SMBJ36CA-13-F (Diodes Incorporated) and SMBJ36CA-TR (STMicroelectronics) provide equivalent performance with different packaging formats. The SMBJ36CD-M3/I variant exhibits minor parameter deviations (57.3V clamping, 10.5A peak pulse) within the same voltage class and remains functionally compatible.

Parts from Central Semiconductor (1SMB36CA TR13 PBFREE) and Littelfuse (SZ1SMB36CAT3G) extend the operating temperature range to -65°C, providing enhanced low-temperature performance. The Littelfuse part includes AEC-Q101 automotive qualification and 245pF capacitance specification at 1MHz.

SMBJ36CA-TP (Micro Commercial Co) supports extended high-temperature operation to 175°C, suitable for elevated thermal environments. MDD's SMBJ36CA variant shows marginal current tolerance variation (10.4A) and reduced low-temperature rating (-50°C minimum).

Frequently Asked Questions (FAQ)

Q: Can SMBJ36CA-E3/52 replace SMBJ36CA-M3/5B directly?

A: Yes. Both parts share identical electrical specifications (36V standoff, 58.1V clamping, 10.3A peak pulse, 600W power rating) and DO-214AA package. The difference is packaging format: SMBJ36CA-E3/52 uses Cut Tape & Digi-Reel® while SMBJ36CA-M3/5B uses Tape & Reel. Electrical performance is equivalent.

Q: What is the significance of the SMBJ36CD-M3/I variant?

A: SMBJ36CD-M3/I maintains the 36V reverse standoff voltage but exhibits slightly different clamping characteristics (57.3V vs 58.1V) and marginally higher peak pulse current (10.5A vs 10.3A). It remains within the same voltage protection class and is functionally compatible for general-purpose applications.

Q: Are there temperature-rated alternatives for extreme environments?

A: Yes. The 1SMB36CA TR13 PBFREE and SZ1SMB36CAT3G extend the minimum operating temperature to -65°C. The SMBJ36CA-TP supports operation to 175°C maximum, compared to the standard 150°C rating of most alternatives.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel, Cut Tape, Digi-Reel®) affects supply chain logistics and handling but does not alter electrical characteristics. All parts in DO-214AA or SMB package are mechanically and electrically interchangeable.

Q: Which substitute offers automotive qualification?

A: The SZ1SMB36CAT3G from Littelfuse includes AEC-Q101 automotive qualification and is suitable for automotive transient protection applications requiring industry certification.

Q: What is the impact of the MDD SMBJ36CA lower temperature rating?

A: The MDD variant specifies -50°C minimum operating temperature versus -55°C for most alternatives. This represents a 5°C reduction in cold-temperature performance and may not be suitable for applications requiring full -55°C operation.
