SMLJ8.0CA-TP Equivalent & Substitute Parts

Part Overview

The SMLJ8.0CA-TP is a bidirectional transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose interface protection applications. This surface-mount component operates with an 8V reverse standoff voltage and provides 3000W peak pulse power dissipation in a compact DO-214AB (SMC) package. The part is currently in active production status with 753 units available in bulk packaging. Substitute parts are identified to address inventory availability, packaging format preferences, or supply chain continuity requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMLJ8.0CA-TP are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 8V
• Voltage - Breakdown (Min): 8.89V
• Voltage - Clamping (Max) @ Ipp: 13.6V
• Current - Peak Pulse (10/1000µs): 220.6A
• Power - Peak Pulse: 3000W
• Bidirectional Channels: 1
• Type: Zener
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount

The SMDJ8.0CA manufactured by Alpha & Omega Semiconductor Inc. meets all critical electrical parameters and maintains the same physical package format. Substitution is valid across these parameters. Differences in packaging format (Tape & Reel versus Bulk) and operating temperature range do not affect functional equivalence for general-purpose interface protection applications.

Parameter Comparison

Engineering Selection Recommendations

SMDJ8.0CA Substitution Validity:

The SMDJ8.0CA is a direct electrical equivalent to the SMLJ8.0CA-TP for general-purpose interface protection applications. All critical voltage, current, and power parameters are identical. Both components are active products with REACH Unaffected status, ensuring regulatory compliance.

Considerations for Selection:

1. Operating Temperature Range: The SMDJ8.0CA operates to 150°C junction temperature, compared to 175°C for the SMLJ8.0CA-TP. Applications requiring operation above 150°C require the original part.

2. Packaging Format: The SMDJ8.0CA is supplied in Tape & Reel format, suitable for automated assembly processes. The SMLJ8.0CA-TP is supplied in Bulk format. Selection depends on manufacturing process requirements and order quantities.

3. Inventory Availability: The SMDJ8.0CA has 12,100 units in stock compared to 753 units for the SMLJ8.0CA-TP, providing greater supply continuity.

4. Compliance: The SMDJ8.0CA carries explicit ROHS3 Compliance certification, while the SMLJ8.0CA-TP compliance status is not specified in available data.

Frequently Asked Questions (FAQ)

Q: Can SMDJ8.0CA replace SMLJ8.0CA-TP in all applications?

A: The SMDJ8.0CA is electrically equivalent for all general-purpose interface protection applications within the operating temperature range of -55°C to 150°C. Applications requiring junction temperatures above 150°C require the original SMLJ8.0CA-TP.

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

A: Bulk packaging is suitable for manual assembly or small-quantity applications. Tape & Reel packaging is designed for automated pick-and-place assembly processes and is standard for high-volume manufacturing. The electrical performance is identical.

Q: Are the DO-214AB and SMC package designations equivalent?

A: Yes. DO-214AB and SMC refer to the same physical package format. Both designations describe a surface-mount diode package with identical dimensions and pin configuration.

Q: Does the SMDJ8.0CA meet RoHS requirements?

A: The SMDJ8.0CA is ROHS3 Compliant. The SMLJ8.0CA-TP RoHS status is not specified in available documentation.

Q: What is the significance of the base product numbers SMLJ8.0 and SMDJ8.0?

A: The base product numbers indicate the voltage rating class (8.0V). The full part numbers include manufacturer-specific suffixes (CA, -TP) that denote packaging, lead configuration, and tape specifications. Both base numbers represent the same electrical specification.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, provided the operating temperature requirements are met. Both parts use identical DO-214AB package dimensions and pin configurations, allowing direct footprint compatibility on PCB designs.
