SMBJ150C-E3/52 Equivalent & Substitute Parts

Part Overview

The SMBJ150C-E3/52 is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division, designed for general-purpose overvoltage protection in surface-mount applications. This part operates with a 150V reverse standoff voltage and provides 268V maximum clamping voltage at peak pulse current. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SMBJ150C-E3/52 is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): Must be 150V
• Bidirectional Channels: Must be 1
• Package / Case: Must be DO-214AA or SMB (surface mount)
• Mounting Type: Must be Surface Mount
• Type: Must be Zener
• Applications: General Purpose

Substitute parts are grouped into two categories based on clamping voltage performance:

Group A - Matched Clamping Voltage (268V): Parts with identical 268V maximum clamping voltage at peak pulse current, maintaining exact electrical performance characteristics of the original part.

Group B - Alternative Clamping Voltage (243V): Parts with 243V maximum clamping voltage at peak pulse current, offering lower clamping performance but maintaining core voltage suppression functionality within the same 150V standoff specification.

All substitute parts maintain the same 150V reverse standoff voltage, 167V minimum breakdown voltage, 600W peak pulse power rating, and DO-214AA/SMB package compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Matched Performance):

SMBJ150CE3/TR13 (Microchip Technology) is the primary direct substitute, maintaining identical 268V clamping voltage and 2.2A peak pulse current specifications. This part is active and ROHS3 compliant with extended operating temperature range (-65°C ~ 150°C), providing superior thermal performance compared to the original obsolete part.

For Alternative Selection (Reduced Clamping Voltage):

SMBJ150CA-E3/52 (Vishay), SMBJ150CA (MDD), SMBJ150CA-13-F (Diodes Incorporated), SMBJ150CA-HR (Littelfuse), and SMBJ150CAE3/TR13 (Microchip) are all active alternatives with 243V clamping voltage and 2.5A peak pulse current. These parts maintain the same 150V reverse standoff voltage and 600W peak pulse power rating. Selection among these alternatives depends on packaging requirements (Tape & Reel vs. bulk) and operating temperature range needs.

SMBJ150CA-HR and SMBJ150CAE3/TR13 offer the widest operating temperature range (-65°C ~ 150°C), suitable for demanding thermal environments. SMBJ150CA (MDD) provides the highest inventory availability at 25,600 pieces.

All substitute parts are ROHS3 compliant, MSL 1 rated, and maintain surface-mount DO-214AA/SMB package compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can SMBJ150CA-E3/52 be used as a direct replacement for SMBJ150C-E3/52?

A: SMBJ150CA-E3/52 is electrically compatible in terms of reverse standoff voltage (150V), breakdown voltage (167V), and package (DO-214AA/SMB). However, it has a lower clamping voltage of 243V compared to the original 268V, and higher peak pulse current (2.5A vs. 2.2A). This substitution is acceptable if your circuit design tolerates the reduced clamping voltage specification.

Q: What is the difference between SMBJ150CE3/TR13 and SMBJ150CAE3/TR13?

A: Both parts are manufactured by Microchip Technology in Tape & Reel packaging. SMBJ150CE3/TR13 maintains the original 268V clamping voltage and 2.2A peak pulse current. SMBJ150CAE3/TR13 has 243V clamping voltage and 2.5A peak pulse current. Select SMBJ150CE3/TR13 for matched electrical performance; select SMBJ150CAE3/TR13 if lower clamping voltage is acceptable and higher current handling is beneficial.

Q: Are all substitute parts available in the same packaging?

A: All substitute parts use the same DO-214AA/SMB surface-mount package. However, packaging format differs: SMBJ150CA-E3/52, SMBJ150CE3/TR13, SMBJ150CA-13-F, SMBJ150CA-HR, and SMBJ150CAE3/TR13 are available in Tape & Reel (TR) format. SMBJ150CA (MDD) is available in bulk packaging. Verify your assembly process requirements before selecting.

Q: Which substitute part has the best thermal performance?

A: SMBJ150CE3/TR13, SMBJ150CA-HR, and SMBJ150CAE3/TR13 all offer the extended operating temperature range of -65°C ~ 150°C, compared to the original part's -55°C ~ 150°C. These three parts are suitable for applications requiring superior thermal performance.

Q: Is inventory availability a factor in selecting a substitute?

A: Yes. SMBJ150CA (MDD) has the highest inventory at 25,600 pieces. SMBJ150CAE3/TR13 has 743 pieces, SMBJ150CE3/TR13 has 872 pieces, SMBJ150CA-13-F has 4,300 pieces, and SMBJ150CA-HR has 999 pieces. Consider lead time and supply chain requirements when selecting among alternatives.
