SMCJ150AE3/TR13 Transient Voltage Suppressor Diode - Equivalent & Substitute Parts

Part Overview

The SMCJ150AE3/TR13 is an active Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, classified as a unidirectional Zener-type device in the DO-214AB (SMC) surface mount package. This component is designed for general-purpose transient voltage protection applications, providing surface mount installation capability with RoHS3 compliance. Alternative equivalent parts are necessary to address supply chain availability, preferred vendor sourcing, packaging format requirements (Tape & Reel versus Bulk), and manufacturer-specific certifications or temperature range specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMCJ150AE3/TR13 are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalents: Parts maintaining identical electrical parameters across all critical specifications—Voltage Reverse Standoff (150V), Voltage Breakdown (167V minimum), Voltage Clamping (243V maximum), and Current Peak Pulse (6.2A)—while differing only in manufacturer identity, packaging format (Tape & Reel versus Bulk), or minor temperature range variations within compatible operating bands. These parts are interchangeable in circuit applications without design modification.

Similar Parts with Enhanced Capability: Parts meeting the same voltage specifications (150V reverse standoff, 167V breakdown, 243V clamping) but providing increased peak pulse current (12.4A to 20.6A) and proportionally higher power dissipation (3000W to 5000W). These parts maintain full electrical compatibility and provide additional surge handling margin, though they occupy the same DO-214AB surface mount package.

The following parameters determine substitution validity:

• Voltage - Reverse Standoff (Typ): Must be 150V
• Voltage - Breakdown (Min): Must be 167V or higher
• Voltage - Clamping (Max): Must not exceed 243V
• Unidirectional Channels: Must be 1
• Package / Case: Must be DO-214AB or SMC
• Mounting Type: Must be Surface Mount
• Product Status: Must be Active

Parameter Comparison

Engineering Selection Recommendations

For applications requiring identical electrical and thermal specifications: Select SMCJ150AE3/TR13 from Microchip Technology (original specification) or the direct equivalent 1SMC150A TR13 PBFREE from Central Semiconductor Corp. Both maintain the -65°C to 150°C operating range with Tape & Reel packaging and RoHS3 compliance.

For applications with relaxed low-temperature requirements (-55°C minimum): Equivalent alternatives include SMCJ150A-13-F (Diodes Incorporated), SMCJ150A-E3/57T (Vishay), and SMCJ150A-TP (Micro Commercial Co). All three maintain 150V reverse standoff, 243V clamping, and 6.2A peak pulse current with RoHS3 certification. SMCJ150A-TP extends the upper temperature limit to 175°C, beneficial for thermally demanding environments.

For applications requiring enhanced surge handling capability: The 5.0SMDJ150A series (MDE Semiconductor Inc or Littelfuse 5.0SMDJ150A-T7) and SMDJ150A (Alpha & Omega Semiconductor Inc.) provide increased peak pulse current and power dissipation while maintaining voltage compatibility. These parts occupy the same DO-214AB surface mount package and support higher transient energy absorption. The Littelfuse 5.0SMDJ150A-T7 variant extends to -65°C operation, matching the original part's thermal specification.

All recommended substitutes maintain Active product status and RoHS3 compliance, ensuring long-term availability and environmental regulatory alignment.

Frequently Asked Questions (FAQ)

Q: What determines whether a TVS diode is a valid substitute for the SMCJ150AE3/TR13?

A: A part is substitutable if it maintains identical Reverse Standoff Voltage (150V), minimum Breakdown Voltage (167V), maximum Clamping Voltage (243V), and operates as a unidirectional Zener device in the DO-214AB surface mount package. Variations in manufacturer, packaging format (Tape & Reel, Bulk, Cut Tape), and operating temperature range do not affect circuit functionality provided the temperature range is compatible with application requirements.

Q: Can I use the 5.0SMDJ150A or SMDJ150A as a direct replacement?

A: Yes. These parts provide higher peak pulse current (12.4A to 20.6A) and power dissipation (3000W to 5000W) compared to the original 6.2A / 1500W specification, while maintaining the same voltage clamping characteristics. They are electrically forward-compatible and provide additional transient protection margin. They occupy the same DO-214AB package and require no design modification for substitution.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Both contain identical electronic components. Tape & Reel packaging provides parts wound on continuous carrier tape suitable for automated pick-and-place assembly equipment. Bulk packaging provides loose components for manual assembly or alternate distribution methods. Both meet identical electrical and RoHS compliance specifications.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range affects substitution only when the application environment exceeds a substitute part's specified limits. The original SMCJ150AE3/TR13 operates from -65°C to 150°C. Parts rated -55°C to 150°C are suitable for applications not requiring sub-zero operation below -55°C. SMCJ150A-TP (extends to 175°C) is appropriate for high-temperature applications.

Q: Are all substitute parts RoHS3 compliant?

A: All recommended substitute parts listed maintain RoHS3 compliance with the exception of generic SMCJ150A variants without specified RoHS certification. When RoHS3 compliance is a requirement, verify certification with the supplier before selection. Microchip Technology (original), Central Semiconductor Corp, Diodes Incorporated, Vishay, Micro Commercial Co, MDE Semiconductor Inc, Littelfuse, and Alpha & Omega Semiconductor Inc. all provide RoHS3-certified variants.

Q: Can I interchange manufacturers within the SMCJ150A series?

A: Yes. All SMCJ150A variants from different manufacturers (Fairchild Semiconductor, Diodes Incorporated, Vishay, Micro Commercial Co) maintain identical electrical parameters and DO-214AB packaging. Selection may be based on availability, preferred vendor agreements, delivery lead time, or packaging format preference.
