Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMLJ5.0CE3/TR13 are qualified based on the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 5V (exact match required)
• Voltage - Breakdown (Min): 6.4V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 9.2V to 9.6V (within tolerance band)
• Current - Peak Pulse (10/1000µs): 163A minimum (supports primary application requirements)
• Power - Peak Pulse: 300W minimum (supports thermal dissipation requirements)
• Type: Zener (exact match required)
• Bidirectional Channels: 1 (exact match required)

Mechanical Compatibility Criteria:

• Package / Case: DO-214AB, SMC (exact match required)
• Mounting Type: Surface Mount (exact match required)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant (required)
• MSL Rating: 1 (Unlimited) or equivalent (required)
• Product Status: Active (required)

Substitute parts meeting all electrical, mechanical, and compliance criteria are listed in the Parameter Comparison table. Variations in peak pulse current and power dissipation above the minimum threshold indicate enhanced performance capability and are acceptable for direct substitution in applications where the primary part is specified.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed in the Parameter Comparison table are qualified for direct substitution with the SMLJ5.0CE3/TR13 based on the following engineering criteria:

Electrical Qualification: All substitute parts maintain the required 5V reverse standoff voltage and 6.4V minimum breakdown voltage. Clamping voltage variations (9.2V versus 9.6V) fall within acceptable tolerance bands for TVS diode applications. Peak pulse current ratings of 163A or higher satisfy the minimum protection requirements. Enhanced power dissipation ratings (1500W to 3000W) provide superior thermal performance compared to the primary part's 300W rating and are acceptable for direct substitution.

Mechanical Qualification: All substitute parts are housed in DO-214AB (SMC) surface-mount packages, ensuring PCB footprint compatibility and assembly process compatibility with the primary part.

Compliance Qualification: All substitute parts are RoHS3 compliant and carry MSL 1 (Unlimited) or equivalent moisture sensitivity ratings, meeting environmental and reliability standards. All parts maintain Active product status, ensuring long-term availability and manufacturing support.

Inventory Availability: Substitute parts demonstrate strong inventory positions, with stock levels ranging from 1,046 to 17,300 units, supporting supply chain continuity and procurement flexibility.

Frequently Asked Questions (FAQ)

Q1: Can SMCJ5.0CA be used as a direct replacement for SMLJ5.0CE3/TR13?

A: Yes. SMCJ5.0CA meets all electrical and mechanical substitution criteria. Both parts operate at 5V reverse standoff voltage with 6.4V minimum breakdown voltage. The clamping voltage of 9.2V on SMCJ5.0CA is within the acceptable tolerance band relative to the primary part's 9.6V specification. Both are housed in DO-214AB (SMC) packages and are RoHS3 compliant with MSL 1 ratings. The primary difference is peak pulse current (171A versus 312.5A), which represents reduced performance capability but remains suitable for applications where the primary part is specified.

Q2: What is the difference between SMDJ5.0CA and SMLJ5.0CA?

A: Both parts are qualified substitutes with identical electrical specifications (5V standoff, 6.4V breakdown, 9.2V clamping). The primary differences are manufacturer (Alpha & Omega Semiconductor Inc. versus Bourns Inc.) and peak pulse current/power ratings (326.1A / 3000W for SMDJ5.0CA versus 326A / 3000W for SMLJ5.0CA). Both provide enhanced thermal performance relative to the primary part and are housed in DO-214AB (SMC) packages.

Q3: Are there any temperature range limitations when substituting parts?

A: Most substitute parts operate across the -55°C to 150°C temperature range, matching the primary part specification. SMDJ5.0CA-T7 extends the lower temperature limit to -65°C, providing enhanced cold-temperature performance. SMCJ5V0CA does not specify an operating temperature range in the provided data. For applications requiring specific temperature performance, verify the substitute part's operating range against application requirements.

Q4: Does packaging format (Tape & Reel versus Cut Tape) affect substitution eligibility?

A: No. Packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) do not affect electrical or mechanical compatibility. These variations address procurement and assembly logistics only. All substitute parts are compatible with standard surface-mount assembly processes.

Q5: What is the significance of the clamping voltage difference between 9.2V and 9.6V?

A: Clamping voltage represents the maximum voltage across the TVS diode during transient suppression. The primary part clamps at 9.6V maximum, while most substitute parts clamp at 9.2V. This 0.4V difference is within typical TVS diode tolerance bands and does not affect circuit protection performance in general-purpose applications. The lower clamping voltage of substitute parts may provide marginally improved protection in sensitive circuits.

Q6: Can SMLJ5.0CA from Bourns Inc. be used in REACH-regulated applications?

A: SMLJ5.0CA is listed as REACH Affected, indicating potential REACH compliance considerations. The primary part (SMLJ5.0CE3/TR13) and most substitute parts are REACH Unaffected. For applications subject to REACH regulations, select substitute parts with REACH Unaffected status: SMCJ5.0CA, SMCJ5.0CA-13-F, SMCJ5V0CA, SMDJ5.0CA, or SMDJ5.0CA-T7.

Q7: Which substitute part offers the highest peak pulse current rating?

A: SMDJ5.0CA and SMDJ5.0CA-T7 both provide 326.1A peak pulse current with 3000W peak pulse power dissipation, representing the highest performance among qualified substitutes. These parts are suitable for applications requiring enhanced transient suppression capability or higher thermal stress conditions.
