SMBJ150E3/TR13 Equivalent & Substitute Parts

Part Overview

The SMBJ150E3/TR13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This component operates with a reverse standoff voltage of 150V and provides clamping at 268V maximum, with a peak pulse current rating of 2.2A. The device is packaged in DO-214AA (SMB) format and supplied on tape and reel. The part maintains active product status and full RoHS3 compliance. Equivalent and substitute parts are identified based on matching electrical performance parameters within the 150V standoff voltage class and compatible surface-mount packaging.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ150E3/TR13 are qualified based on the following criteria:

Primary Matching Parameters:

• Voltage - Reverse Standoff (Typ): 150V
• Voltage - Breakdown (Min): 167V
• Package / Case: DO-214AA or SMB
• Mounting Type: Surface Mount
• Unidirectional Channels: 1
• Applications: General Purpose
• RoHS3 Compliance: Required

Secondary Compatibility Factors:

• Voltage - Clamping (Max) @ Ipp: Within acceptable range for the application class
• Current - Peak Pulse (10/1000µs): Equal or greater capacity
• Power - Peak Pulse: 600W rating maintained
• Operating Temperature Range: Minimum -50°C to maximum 150°C
• Product Status: Active

Substitute parts SMBJ150A (MDD) and SMBJ150A-13-F (Diodes Incorporated) meet all primary matching parameters. Both maintain the 150V standoff voltage, 167V minimum breakdown voltage, and SMB/DO-214AA packaging. Clamping voltage variations (243V versus 268V) and peak pulse current differences (2.5A versus 2.2A) remain within the electrical performance envelope for this component class.

Parameter Comparison

Engineering Selection Recommendations

SMBJ150A (MDD) qualifies as a direct substitute based on matching reverse standoff voltage (150V), breakdown voltage (167V), and SMB/DO-214AA packaging. The part maintains active product status, ROHS3 compliance, and unlimited moisture sensitivity rating. The clamping voltage of 243V and peak pulse current of 2.5A provide equivalent or superior performance within the 150V protection class. Operating temperature range of -50°C to 150°C covers standard industrial applications, though the minimum temperature is 15°C higher than the original part.

SMBJ150A-13-F (Diodes Incorporated) is qualified as an equivalent substitute with identical standoff and breakdown voltages, SMB packaging, and active product status. This part is supplied on tape and reel, matching the original packaging format. ROHS3 compliance and unlimited moisture sensitivity are maintained. The operating temperature range of -55°C to 150°C provides extended low-temperature performance compared to the MDD variant. Clamping voltage (243V) and peak pulse current (2.5A) remain within acceptable parameters for this component class.

Both substitute parts satisfy compliance requirements (ROHS3, REACH Unaffected) and maintain the same electrical protection function for general-purpose transient suppression applications.

Frequently Asked Questions (FAQ)

Q: Can SMBJ150A (MDD) be used as a direct replacement for SMBJ150E3/TR13?

A: Yes. Both parts share the same 150V reverse standoff voltage, 167V minimum breakdown voltage, and DO-214AA/SMB surface-mount packaging. The clamping voltage difference (243V versus 268V) and increased peak pulse current (2.5A versus 2.2A) represent equivalent or improved performance within the 150V protection class. Both maintain ROHS3 compliance and active product status.

Q: What is the difference between SMBJ150A-13-F and SMBJ150A?

A: SMBJ150A-13-F is manufactured by Diodes Incorporated and supplied on tape and reel, while SMBJ150A is manufactured by MDD with unspecified packaging format. Both share identical electrical parameters (150V standoff, 167V breakdown, 243V clamping, 2.5A peak pulse). SMBJ150A-13-F offers a slightly lower minimum operating temperature (-55°C versus -50°C).

Q: Are there any temperature range limitations when substituting these parts?

A: The original SMBJ150E3/TR13 operates from -65°C to 150°C. SMBJ150A (MDD) operates from -50°C to 150°C, representing a 15°C higher minimum temperature limit. SMBJ150A-13-F operates from -55°C to 150°C, providing a 10°C higher minimum limit. Applications requiring operation below -55°C must use the original Microchip part.

Q: Do all three parts use the same package format?

A: Yes. All three parts use DO-214AA/SMB surface-mount packaging, ensuring mechanical and electrical compatibility on printed circuit boards. The original part is supplied on tape and reel; SMBJ150A-13-F is also supplied on tape and reel, while SMBJ150A packaging format is not specified in available data.

Q: Are substitute parts RoHS3 compliant?

A: Yes. Both SMBJ150A (MDD) and SMBJ150A-13-F (Diodes Incorporated) are ROHS3 compliant and REACH unaffected, matching the compliance status of the original SMBJ150E3/TR13.

Q: What is the significance of the clamping voltage difference (268V versus 243V)?

A: The clamping voltage represents the maximum voltage across the diode during transient suppression. The original part clamps at 268V maximum, while substitutes clamp at 243V maximum. The lower clamping voltage of substitute parts provides tighter voltage regulation during transient events, which is acceptable for general-purpose protection applications within the 150V standoff class.
