Part Overview

The SMCJ150E3/TR13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This surface-mount component operates with a 150V reverse standoff voltage and provides clamping at 268V maximum, with a peak pulse current rating of 5.6A and peak pulse power of 1500W. The device is housed in a DO-214AB (SMC) package and is supplied in Tape & Reel packaging.

The SMCJ150E3/TR13 maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified based on matching or compatible electrical and mechanical parameters within the TVS diode category, enabling direct or near-direct replacement in circuit designs where voltage regulation and transient suppression requirements align.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMCJ150E3/TR13 are qualified based on the following critical parameters:

Voltage Parameters: All substitute parts must maintain a 150V reverse standoff voltage (Typ) and 167V minimum breakdown voltage to ensure equivalent transient protection thresholds. Clamping voltage at peak pulse current may vary within acceptable design margins.

Current and Power Ratings: Substitute parts must support the same or higher peak pulse current (10/1000µs) and peak pulse power ratings. Parts with equal or superior current/power handling provide direct substitution capability.

Package and Mounting: All substitutes use the DO-214AB (SMC) surface-mount package, ensuring mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Electrical Type: All substitutes are unidirectional Zener-type TVS diodes with single channel configuration, matching the functional topology of the main part.

Compliance and Status: All substitute parts maintain Active product status and RoHS3 compliance, ensuring regulatory alignment and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Equivalent Performance):

The SMCJ150A (Fairchild Semiconductor) and SMCJ150A-13-F (Diodes Incorporated) provide direct electrical equivalence to the SMCJ150E3/TR13. Both parts maintain identical voltage parameters (150V standoff, 167V breakdown), equivalent peak pulse current (6.2A), and matching power dissipation (1500W). These parts are suitable for one-to-one replacement in existing designs. Both maintain Active product status and RoHS3 compliance. The SMCJ150A-13-F offers Cut Tape and Digi-Reel packaging options, while the standard SMCJ150A is supplied in Bulk format.

Enhanced Performance Substitutes:

The 5.0SMDJ150A (MDE Semiconductor Inc) and SMDJ150A (Alpha & Omega Semiconductor Inc) provide superior current and power handling capabilities while maintaining the same voltage protection thresholds. The 5.0SMDJ150A delivers 20.6A peak pulse current and 5000W peak pulse power, while the SMDJ150A provides 12.4A and 3000W respectively. These parts are suitable for applications requiring higher transient energy absorption. Both are supplied in Tape & Reel format and maintain RoHS3 compliance and Active product status.

Temperature Range Consideration:

The SMCJ150E3/TR13 operates across -65°C to 150°C. All substitute parts operate within -55°C to 150°C, representing a narrower lower temperature range. Applications requiring operation below -55°C must retain the original SMCJ150E3/TR13 specification.

Packaging and Supply Chain:

All substitute parts use the DO-214AB (SMC) surface-mount package, ensuring PCB layout compatibility. Packaging format varies: Tape & Reel format is available from Microchip (original), MDE Semiconductor, and Alpha & Omega Semiconductor; Bulk and Cut Tape formats are available from Fairchild and Diodes Incorporated respectively.

Frequently Asked Questions (FAQ)

Q: Can the SMCJ150A directly replace the SMCJ150E3/TR13?

A: Yes. The SMCJ150A (Fairchild Semiconductor) provides direct electrical substitution. Both parts share identical voltage parameters (150V standoff, 167V breakdown), equivalent peak pulse current (6.2A), and matching power dissipation (1500W). The DO-214AB package ensures mechanical compatibility. Packaging format differs (Bulk vs. Tape & Reel), but electrical performance is equivalent.

Q: What is the difference between the SMCJ150A and SMDJ150A?

A: Both parts maintain the same 150V voltage protection threshold and 243V clamping voltage. The primary difference is peak pulse current and power handling: SMCJ150A provides 6.2A and 1500W, while SMDJ150A provides 12.4A and 3000W. The SMDJ150A is suitable for applications requiring higher transient energy absorption. Both use the DO-214AB package and maintain RoHS3 compliance.

Q: Why does the 5.0SMDJ150A have a lower clamping voltage (243V vs. 268V)?

A: Clamping voltage variation within the 150V voltage class is a normal characteristic of different TVS diode designs. The 5.0SMDJ150A clamps at 243V maximum, compared to 268V for the SMCJ150E3/TR13. Both maintain the same 150V standoff and 167V breakdown voltages, ensuring equivalent protection thresholds. The lower clamping voltage of the 5.0SMDJ150A may provide tighter voltage regulation in some applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (5.0SMDJ150A, SMCJ150A, SMCJ150A-13-F, and SMDJ150A) are RoHS3 compliant, matching the compliance status of the SMCJ150E3/TR13. All parts maintain unlimited moisture sensitivity level (MSL 1).

Q: What is the temperature range limitation for substitute parts?

A: The SMCJ150E3/TR13 operates from -65°C to 150°C. All substitute parts operate from -55°C to 150°C, representing a 10°C narrower lower temperature range. Applications requiring operation below -55°C must use the original SMCJ150E3/TR13 specification.

Q: Can I use the 5.0SMDJ150A in place of the SMCJ150E3/TR13 for higher energy transients?

A: Yes. The 5.0SMDJ150A maintains the same 150V voltage protection threshold and provides superior current (20.6A) and power (5000W) handling compared to the original part (5.6A, 1500W). The lower clamping voltage (243V vs. 268V) provides tighter voltage regulation. This part is suitable for applications with higher transient energy requirements while maintaining the same protection voltage class.

Q: What packaging options are available for substitutes?

A: Tape & Reel format is available from Microchip (original), MDE Semiconductor (5.0SMDJ150A), and Alpha & Omega Semiconductor (SMDJ150A). Bulk format is available from Fairchild (SMCJ150A). Cut Tape and Digi-Reel format is available from Diodes Incorporated (SMCJ150A-13-F). All parts use the DO-214AB (SMC) surface-mount package.

Q: Are all substitute parts in Active product status?

A: Yes. All listed substitute parts maintain Active product status, ensuring ongoing availability and supply chain support. The SMCJ150E3/TR13 original part also maintains Active status.
