SMCJ8.0CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMCJ8.0CE3/TR13 is a bidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This component features an 8V reverse standoff voltage with a 15V maximum clamping voltage and 100A peak pulse current capability in a DO-214AB (SMC) package. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching or compatible electrical characteristics within the TVS diode category, specifically reverse standoff voltage, clamping voltage, peak pulse current, and power dissipation ratings, combined with identical or functionally equivalent packaging and surface-mount configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMCJ8.0CE3/TR13 are identified based on the following critical electrical and mechanical parameters:

Primary Matching Criteria:

• Reverse standoff voltage: 8V (nominal)
• Breakdown voltage minimum: 8.89V
• Bidirectional channel configuration: 1 channel
• Package type: DO-214AB / SMC surface mount
• Zener diode type classification
• General-purpose application category

Secondary Compatibility Factors:

• Clamping voltage range: 13.6V to 15V maximum
• Peak pulse current: 82.4A to 220.6A
• Peak pulse power: 1500W to 3000W
• Operating temperature range: -55°C to -65°C minimum, 150°C maximum
• RoHS3 compliance and REACH unaffected status
• Active product status

Substitute parts maintain the same reverse standoff voltage specification and breakdown characteristics while accommodating variations in clamping voltage, peak pulse current handling, and power dissipation within the TVS diode functional envelope. All substitutes are surface-mount, single-channel bidirectional devices in DO-214AB packaging.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (8V Reverse Standoff Voltage):

The SMCJ8.0CA-13-F (Diodes Incorporated) and SMCJ8.0CA (Taiwan Semiconductor Corporation) are direct functional equivalents to the SMCJ8.0CE3/TR13. Both maintain the 8V reverse standoff voltage and 8.89V minimum breakdown voltage. The SMCJ8.0CA-13-F provides 110.3A peak pulse current with 13.6V clamping voltage, while the SMCJ8.0CA offers 115A peak pulse current with identical 13.6V clamping. Both are RoHS3 compliant, Active status products suitable for direct substitution in general-purpose TVS applications.

Higher Current Capability Alternative:

The SMDJ8.0CA (Alpha & Omega Semiconductor Inc.) maintains the 8V reverse standoff voltage and 8.89V breakdown voltage but provides enhanced performance with 220.6A peak pulse current and 3000W peak pulse power dissipation. This part is suitable for applications requiring higher transient current handling while maintaining the same voltage protection characteristics. RoHS3 compliance and Active status are confirmed.

Higher Voltage Alternative:

The SMCJ11CA-13-F (Diodes Incorporated) operates at an 11V reverse standoff voltage with 12.2V minimum breakdown voltage, representing a higher voltage protection tier. This part is not a direct equivalent but serves applications requiring elevated voltage suppression. Peak pulse current is 82.4A with 18.2V clamping voltage. RoHS3 compliance and Active status are maintained.

All substitute parts are manufactured by established semiconductor suppliers, maintain RoHS3 compliance, and carry Active product status. Selection should be based on specific circuit voltage requirements and transient current handling specifications.

Frequently Asked Questions (FAQ)

Q: Can SMCJ8.0CA-13-F replace SMCJ8.0CE3/TR13 directly?

A: Yes. Both parts share identical 8V reverse standoff voltage, 8.89V minimum breakdown voltage, and DO-214AB surface-mount packaging. The SMCJ8.0CA-13-F provides 110.3A peak pulse current versus 100A in the original part, with 13.6V clamping voltage versus 15V. Both maintain 1500W peak pulse power and are RoHS3 compliant with Active product status.

Q: What is the difference between SMCJ8.0CA and SMCJ8.0CA-13-F?

A: Both parts are manufactured by different suppliers (Taiwan Semiconductor Corporation versus Diodes Incorporated) but share identical electrical specifications: 8V reverse standoff, 8.89V breakdown, 13.6V clamping, and 1500W peak pulse power. The SMCJ8.0CA provides 115A peak pulse current; the SMCJ8.0CA-13-F provides 110.3A. Packaging designation differs (DO-214AB (SMC) versus SMC), but both are surface-mount DO-214AB devices.

Q: When should SMDJ8.0CA be selected instead of SMCJ8.0CE3/TR13?

A: The SMDJ8.0CA is selected when circuit design requires higher transient current handling capability. It provides 220.6A peak pulse current and 3000W peak pulse power dissipation compared to 100A and 1500W in the original part. Voltage protection characteristics remain identical at 8V reverse standoff. This part is suitable for high-energy transient environments.

Q: Is SMCJ11CA-13-F compatible with SMCJ8.0CE3/TR13 applications?

A: SMCJ11CA-13-F is not a direct equivalent. It operates at 11V reverse standoff voltage versus 8V, making it unsuitable for circuits designed for 8V protection. This part is specified for higher voltage protection applications. Use only when circuit design explicitly requires 11V or higher voltage suppression.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts—SMCJ8.0CA-13-F, SMCJ8.0CA, SMCJ11CA-13-F, and SMDJ8.0CA—are RoHS3 compliant and REACH unaffected, matching the compliance status of SMCJ8.0CE3/TR13.

Q: What is the operating temperature difference between SMCJ8.0CE3/TR13 and substitute parts?

A: SMCJ8.0CE3/TR13 operates from -65°C to 150°C. All substitute parts (SMCJ8.0CA-13-F, SMCJ8.0CA, SMCJ11CA-13-F, SMDJ8.0CA) operate from -55°C to 150°C. The original part provides 10°C lower minimum temperature operation. For applications requiring -65°C operation, SMCJ8.0CE3/TR13 must be retained.

Q: Do all substitute parts use the same DO-214AB package?

A: Yes. All substitute parts use DO-214AB surface-mount packaging, also designated as SMC. This ensures mechanical and electrical compatibility with PCB layouts designed for SMCJ8.0CE3/TR13.

Q: What inventory availability exists for substitute parts?

A: SMCJ8.0CA (Taiwan Semiconductor Corporation) has 84,100 pieces in stock. SMDJ8.0CA (Alpha & Omega) has 12,100 pieces. SMCJ11CA-13-F (Diodes Incorporated) has 3,600 pieces. SMCJ8.0CA-13-F (Diodes Incorporated) has 787 pieces. Original SMCJ8.0CE3/TR13 has 805 pieces in stock.
