SMBJ36A-TP Equivalent & Substitute Parts

Part Overview

The SMBJ36A-TP is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection in surface-mount applications. The device features a 36V reverse standoff voltage with a 58.1V maximum clamping voltage and 10.3A peak pulse current capability. It is packaged in DO-214AA (SMB) format on Tape & Reel (TR) and maintains Active product status with full RoHS3 compliance. Substitute parts are identified when electrical parameters and mechanical compatibility align within specified tolerances, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ36A-TP are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes maintain identical or equivalent electrical specifications:

• Voltage - Reverse Standoff (Typ): 36V
• Voltage - Clamping (Max) @ Ipp: 58.1V
• Current - Peak Pulse: 10.3A to 10.4A
• Package / Case: DO-214AA or DO-214AC (SMB/SMA)
• Power - Peak Pulse: 600W
• RoHS3 Compliance: Required

Similar Substitutes share the same reverse standoff voltage and general application but exhibit variations in clamping voltage or peak pulse current within acceptable operating margins for the 36V protection class.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Preferred): SMBJ36A-13-F (Diodes Incorporated), SMBJ36A-E3/52 (Vishay), SMBJ36A-E3/5B (Vishay), and SMBJ36A-M3/52 (Vishay) are functionally equivalent to SMBJ36A-TP. All maintain 36V reverse standoff, 58.1V clamping voltage, and 10.3A peak pulse current. All are packaged in DO-214AA (SMB) format and carry Active product status with ROHS3 compliance. These parts are suitable for direct PCB replacement without circuit redesign.

SMBJ36A (EVVO Semi) provides electrical equivalence with 10.4A peak pulse current and maintains 58.1V clamping voltage. The package variant (DO-214AC, SMA) differs mechanically; footprint compatibility must be verified before selection.

Similar Substitutes (Application-Dependent): SACB36 (Littelfuse Inc.) shares the 36V reverse standoff voltage class but exhibits 60V clamping voltage and 8.6A peak pulse current. This part is suitable for applications where slightly higher clamping voltage and lower peak current capacity are acceptable within system design margins.

SM6T42AY (STMicroelectronics) operates at 36V reverse standoff with 76V clamping voltage and significantly higher peak pulse current (52A at 8/20µs). This part is qualified to AEC-Q101 automotive standards and is suitable for high-energy transient suppression applications requiring enhanced current handling. Selection requires verification that the elevated clamping voltage does not exceed downstream component voltage ratings.

All substitute parts maintain RoHS3 compliance and Unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard manufacturing and storage practices.

Frequently Asked Questions (FAQ)

Q: Can SMBJ36A (EVVO Semi) replace SMBJ36A-TP in existing designs? A: Electrical parameters are equivalent (36V standoff, 58.1V clamp, 10.4A peak pulse). However, the package differs: SMBJ36A uses DO-214AC (SMA) while SMBJ36A-TP uses DO-214AA (SMB). PCB footprint compatibility must be confirmed before substitution.

Q: What is the difference between SMBJ36A-E3/5B and SMBJ36A-M3/52? A: Both are Vishay TransZorb® series devices with identical electrical specifications (36V standoff, 58.1V clamp, 10.3A peak pulse) and DO-214AA (SMB) packaging. The suffix designations indicate different manufacturing codes or tape configurations. Electrical performance is equivalent for circuit applications.

Q: Is SACB36 a suitable replacement for SMBJ36A-TP? A: SACB36 maintains the 36V reverse standoff voltage class but exhibits 60V clamping voltage (versus 58.1V) and 8.6A peak pulse current (versus 10.3A). Substitution is acceptable if the circuit design accommodates the higher clamping voltage and lower peak current capacity. System-level validation is required.

Q: When should SM6T42AY be selected over SMBJ36A-TP? A: SM6T42AY is selected for high-energy transient suppression applications requiring 52A peak pulse current capability and AEC-Q101 automotive qualification. The 76V clamping voltage is higher than SMBJ36A-TP; verify that downstream components tolerate this voltage level before substitution.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 Compliant status and maintain Unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard manufacturing processes and environmental storage conditions.

Q: What packaging options are available for 36V TVS diodes in this category? A: Direct substitutes are available in DO-214AA (SMB) format, matching SMBJ36A-TP. SMBJ36A (EVVO Semi) is available in DO-214AC (SMA) format. Package selection depends on PCB footprint design and assembly equipment compatibility.
