SMLJ10CA-TP Equivalent & Substitute Parts

Part Overview

The SMLJ10CA-TP is a transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection in surface-mount applications. This bidirectional Zener diode operates with a 10V reverse standoff voltage and 17V maximum clamping voltage, delivering 176.4A peak pulse current at 3000W peak pulse power in a DO-214AB (SMC) package. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility across multiple manufacturers is required while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMLJ10CA-TP is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 10V
• Voltage - Breakdown (Min): 11.1V
• Voltage - Clamping (Max) @ Ipp: 17V
• Current - Peak Pulse (10/1000µs): 176.4A (±0.1A tolerance acceptable)
• Power - Peak Pulse: 3000W
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener

Direct Equivalents meet all primary criteria and are interchangeable without circuit modification.

Similar Substitutes deviate in one or more electrical parameters (voltage clamping, peak pulse current, or power rating) and require circuit-level evaluation before implementation.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Full Interchangeability):

SMDJ10CA (Alpha & Omega Semiconductor Inc.) and SMDJ10CA-T7 (Littelfuse) are direct electrical equivalents with identical voltage and current specifications. Both are ROHS3 compliant and supplied in Tape & Reel packaging. SMDJ10CA-T7 offers an extended lower operating temperature limit (-65°C vs. -55°C), providing additional thermal margin for cold-environment applications.

SMLJ10CA (Bourns Inc.) matches all electrical parameters and maintains the same 3000W power rating. This part is ROHS3 compliant and available in Tape & Reel format. The operating temperature range is -55°C ~ 150°C, which is 25°C lower than the primary part at the upper limit.

Similar Substitutes (Reduced Performance):

SMCJ10CA (Fairchild Semiconductor) operates at identical voltage levels but delivers only 88.3A peak pulse current and 1500W peak pulse power—50% of the primary part's specifications. This part is suitable only for applications with lower transient energy requirements and is supplied in Bulk packaging rather than Tape & Reel.

SMCJ11CA-13-F (Diodes Incorporated) has a 1V higher reverse standoff voltage (11V vs. 10V) and 1.2V higher clamping voltage (18.2V vs. 17V), with reduced peak pulse current (82.4A) and power (1500W). This part is appropriate only for circuits designed for the higher voltage specification.

Compliance and Certification:

All recommended direct equivalents carry ROHS3 compliance certification. REACH status is unaffected for all parts. Moisture sensitivity level is rated at MSL 1 (Unlimited) for all parts with specified ratings.

Frequently Asked Questions (FAQ)

Q: Can SMCJ10CA replace SMLJ10CA-TP directly?

A: No. While SMCJ10CA shares the same package and voltage specifications, it delivers only 88.3A peak pulse current versus 176.4A for the SMLJ10CA-TP, and half the peak pulse power (1500W vs. 3000W). Direct substitution will result in inadequate transient suppression in high-energy applications.

Q: What is the difference between SMDJ10CA and SMLJ10CA?

A: Both parts are direct electrical equivalents with identical voltage and current ratings. The primary difference is manufacturer: SMDJ10CA is from Alpha & Omega Semiconductor Inc., while SMLJ10CA is from Bourns Inc. Both are suitable for direct substitution in the SMLJ10CA-TP application.

Q: Does operating temperature range affect substitution?

A: The SMLJ10CA-TP operates to 175°C junction temperature. Direct equivalents SMDJ10CA, SMLJ10CA, and SMCJ10CA are rated to 150°C. For applications requiring operation above 150°C, the primary part or SMDJ10CA-T7 (which extends to -65°C minimum) should be evaluated for thermal margin. The 25°C difference at the upper limit may be significant in high-temperature environments.

Q: Are Tape & Reel and Bulk packaging interchangeable?

A: Tape & Reel and Bulk packaging formats are mechanically and electrically identical; the difference is in delivery and handling format. Tape & Reel is standard for automated assembly lines, while Bulk is suitable for manual assembly or lower-volume applications. Component performance is not affected by packaging format.

Q: Can SMCJ11CA-13-F be used in a circuit designed for SMLJ10CA-TP?

A: No. SMCJ11CA-13-F has a 1V higher reverse standoff voltage and 1.2V higher clamping voltage. Using this part in a 10V-rated circuit will cause the suppressor to trigger at a higher voltage threshold, potentially allowing overvoltage transients to reach protected components before suppression occurs.

Q: What does "Bidirectional Channels: 1" mean?

A: This indicates a single bidirectional TVS diode that suppresses transients in both polarities. All listed parts are single-channel bidirectional devices suitable for protecting circuits against both positive and negative voltage transients.
