SMCJ150A-TP Equivalent & Substitute Parts

Part Overview

The SMCJ150A-TP is a unidirectional transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection in surface-mount applications. This component features a 150V reverse standoff voltage with a 243V maximum clamping voltage and 6.2A peak pulse current capability in a DO-214AB (SMC) package. The part is Active status and RoHS3 compliant, making it suitable for modern electronic designs requiring transient voltage suppression.

Substitute Part Grouping Explanation

Substitute parts for the SMCJ150A-TP are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes maintain identical electrical specifications:

Voltage - Reverse Standoff: 150V
Voltage - Breakdown (Min): 167V
Voltage - Clamping (Max) @ Ipp: 243V
Current - Peak Pulse: 6.2A
Power - Peak Pulse: 1500W
Package / Case: DO-214AB, SMC
Type: Zener, Unidirectional (1 channel)

Similar Substitutes share the same voltage ratings and package but differ in peak pulse current and power dissipation capabilities, suitable for applications requiring higher transient energy absorption.

Frequently Asked Questions (FAQ)

Q: Can I use a higher power-rated TVS diode as a substitute for SMCJ150A-TP?

A: Yes. The 5.0SMDJ150A, 5.0SMDJ150A-T7, and SMDJ150A maintain identical voltage specifications (150V reverse standoff, 243V clamping) and package format (DO-214AB, SMC) while providing increased peak pulse current and power dissipation. These are suitable for circuits where transient energy absorption exceeds 1500W.

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

A: Tape & Reel (TR) packaging is used for automated assembly processes and provides components on continuous tape. Bulk packaging is used for manual assembly or lower-volume applications. Electrical performance is identical; packaging choice depends on manufacturing process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the operating temperature range difference between SMCJ150A-TP and its substitutes?

A: SMCJ150A-TP operates from -55°C to 175°C. Most direct substitutes operate from -55°C to 150°C, with some options (1SMC150A TR13 PBFREE and 5.0SMDJ150A-T7) extending to -65°C minimum. Select substitutes based on your circuit's minimum operating temperature requirement.

Q: Can I substitute SMCJ150A-TP with a part from a different manufacturer?

A: Yes. All listed substitutes from Central Semiconductor Corp, Fairchild Semiconductor, Diodes Incorporated, Vishay, MDE Semiconductor Inc, Littelfuse, and Alpha & Omega Semiconductor Inc. are electrically equivalent or compatible alternatives with identical voltage and package specifications.

Q: What does "Moisture Sensitivity Level (MSL) 1 (Unlimited)" mean?

A: MSL 1 indicates the component has unlimited shelf life and does not require special moisture-control storage conditions. This applies to SMCJ150A-TP and all listed substitutes.
