Substitute Part Grouping Explanation

Substitute parts for the SMCJ90E3/TR13 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

Voltage - Reverse Standoff (Typ): 90V
Voltage - Breakdown (Min): 100V
Unidirectional Channels: 1
Package / Case: DO-214AB, SMC
Mounting Type: Surface Mount
Type: Zener

Allowable Variation Parameters:

Voltage - Clamping (Max) @ Ipp: Range 146V to 160V
Current - Peak Pulse (10/1000µs): Range 9.4A to 34.3A
Power - Peak Pulse: Range 1500W to 5000W
Operating Temperature Range: Minimum -55°C to maximum 175°C

All substitute parts maintain identical reverse standoff and breakdown voltage specifications, ensuring equivalent circuit protection thresholds. Variations in clamping voltage, peak pulse current, and power dissipation capacity reflect different device series within the same voltage class and package format. These variations are acceptable for substitution when the application requirements do not exceed the substitute part's electrical ratings.

Engineering Selection Recommendations

All identified substitute parts maintain ROHS3 compliance and are classified as active products in current production. Selection among equivalent parts is determined by application-specific requirements:

SMCJ90A (Fairchild Semiconductor) and SMCJ90A-13-F (Diodes Incorporated) provide the closest electrical match to the SMCJ90E3/TR13, with identical 1500W peak pulse power rating and 10.3A peak pulse current. These parts are suitable for direct replacement in applications with equivalent or lower power dissipation requirements. SMCJ90A-13-F is supplied in tape and reel packaging, matching the original part's packaging format.

SMDJ90A (Alpha & Omega Semiconductor Inc.) and SMLJ90A (Bourns Inc.) offer increased current handling capacity at 20.6A and 3000W peak pulse power. These parts are applicable in applications requiring enhanced transient energy absorption while maintaining the same voltage protection threshold.

5.0SMDJ90A (Taiwan Semiconductor Corporation) provides maximum current handling at 34.3A and 5000W peak pulse power, with extended operating temperature range to 175°C. This part is suitable for high-energy transient environments or applications requiring elevated temperature operation.

All substitute parts are compatible with the DO-214AB (SMC) surface-mount package and maintain the same reverse standoff and breakdown voltage specifications as the original part.

Frequently Asked Questions (FAQ)

Q: Can SMCJ90A substitute for SMCJ90E3/TR13 in all applications?

A: SMCJ90A is electrically equivalent for voltage protection thresholds (90V reverse standoff, 100V breakdown minimum). The primary difference is clamping voltage at peak pulse current: SMCJ90A clamps at 146V compared to SMCJ90E3/TR13 at 160V. This lower clamping voltage provides tighter voltage regulation and is acceptable in applications where the protected circuit can tolerate 146V maximum transient voltage. Peak pulse current is comparable at 10.3A versus 9.4A.

Q: What is the difference between SMCJ90A and SMDJ90A?

A: Both parts share identical voltage specifications (90V reverse standoff, 100V breakdown, 146V clamping). SMDJ90A provides higher peak pulse current at 20.6A and 3000W power dissipation compared to SMCJ90A at 10.3A and 1500W. SMDJ90A is suitable for applications with higher transient energy levels. Both use the DO-214AB (SMC) package.

Q: Is 5.0SMDJ90A compatible with the original SMCJ90E3/TR13 footprint?

A: Yes. 5.0SMDJ90A uses the same DO-214AB (SMC) surface-mount package and is mechanically compatible. Electrically, it maintains the same 90V reverse standoff and 100V breakdown voltage. The primary differences are enhanced current handling (34.3A versus 9.4A) and power dissipation (5000W versus 1500W), with slightly lower clamping voltage at 146V. This part is suitable for high-energy transient protection applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitute parts are ROHS3 compliant, matching the compliance status of the original SMCJ90E3/TR13.

Q: What is the significance of clamping voltage differences between substitute parts?

A: Clamping voltage determines the maximum voltage that appears across the protected circuit during a transient event. The SMCJ90E3/TR13 clamps at 160V maximum, while most substitutes clamp at 146V. Lower clamping voltage provides better protection for sensitive components but requires verification that the protected circuit can tolerate the specified maximum voltage. Selection depends on the voltage rating of downstream components.

Q: Can SMLJ90A replace SMCJ90A-13-F?

A: Yes. Both parts share identical voltage specifications (90V reverse standoff, 100V breakdown, 146V clamping) and current ratings (20.6A peak pulse, 3000W power). Both use the DO-214AB (SMC) package. The primary difference is manufacturer and packaging format. SMLJ90A is supplied in tape and reel format, as is SMCJ90A-13-F.

Q: What operating temperature range should be considered for substitute selection?

A: The original SMCJ90E3/TR13 operates from -65°C to 150°C. Most substitute parts operate from -55°C to 150°C, with 5.0SMDJ90A extending to 175°C. For applications requiring operation below -55°C, the original part or equivalent parts with -65°C minimum rating are required. For applications requiring operation above 150°C, 5.0SMDJ90A is the only qualified substitute.
