Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, ensuring compliance with environmental and regulatory requirements equivalent to the SMCJ150CE3/TR13.

Selection Considerations Based on Provided Parameters:

SMCJ150CA (Meritek): Maintains identical reverse standoff voltage (150V), breakdown voltage (167V), and power rating (1500W) as the original part. Peak pulse current is 6.17A with clamping voltage of 243V. Operating temperature range is -55°C to 150°C. This part provides direct functional equivalence with minimal parameter variation.

SMCJ150CA-13-F (Diodes Incorporated): Offers equivalent electrical performance with 150V standoff, 167V breakdown, and 1500W power rating. Peak pulse current is 6.2A with 243V clamping. Operating temperature range is -55°C to 150°C. Suitable for applications requiring consistent performance across the specified temperature range.

SMCJ150CA-TP (Micro Commercial Co): Provides extended operating temperature range of -55°C to 175°C, compared to the original -65°C to 150°C. Electrical parameters match the SMCJ150CA-13-F variant. This option is applicable for applications requiring higher maximum junction temperature operation.

SMDJ150CA (Alpha & Omega Semiconductor Inc.): Delivers higher peak pulse current (12.4A) and power dissipation (3000W) while maintaining the same reverse standoff and breakdown voltages. Clamping voltage is 243V. This part accommodates applications with higher transient energy requirements.

SMLJ150CA (Bourns Inc.): Equivalent to SMDJ150CA with 12.4A peak pulse current and 3000W power rating. Maintains 150V standoff and 167V breakdown voltages. Highest inventory availability (30,300 pcs) among substitute options.

5.0SMDJ150CA (MDE Semiconductor Inc): Provides maximum peak pulse current (20.6A) and power dissipation (5000W) among all listed substitutes. Maintains 150V standoff and 167V breakdown voltages with 243V clamping. Operating temperature range is -55°C to 150°C. Applicable for high-energy transient suppression applications.

Frequently Asked Questions (FAQ)

Q: Can SMCJ150CA substitute for SMCJ150CE3/TR13 in all applications?

A: SMCJ150CA maintains the same reverse standoff voltage (150V), breakdown voltage (167V), and power rating (1500W) as the original part. The clamping voltage is 243V compared to 268V on the original. Both parts are RoHS3 compliant with MSL 1. Substitution is valid where the 243V clamping voltage is acceptable for the circuit design.

Q: What is the difference between SMCJ150CA and SMDJ150CA?

A: Both parts share identical reverse standoff (150V) and breakdown (167V) voltages. SMDJ150CA provides higher peak pulse current (12.4A versus 6.17A) and power dissipation (3000W versus 1500W). SMDJ150CA is suitable for applications requiring greater transient energy handling capacity.

Q: Are all substitute parts in the same DO-214AB package?

A: Yes, all substitute parts listed are housed in the DO-214AB (SMC) surface mount package, ensuring mechanical and footprint compatibility with the original SMCJ150CE3/TR13.

Q: Does operating temperature range affect substitution compatibility?

A: The original SMCJ150CE3/TR13 operates from -65°C to 150°C. Most substitute parts operate from -55°C to 150°C, representing a narrower minimum temperature range. SMCJ150CA-TP extends the maximum to 175°C. Substitution is valid where the substitute part's operating temperature range encompasses the application's requirements.

Q: What is the significance of the clamping voltage difference between 268V and 243V?

A: The clamping voltage determines the maximum voltage the TVS diode allows across the protected circuit during a transient event. The original part clamps at 268V maximum, while most substitutes clamp at 243V. Lower clamping voltage provides tighter protection but requires verification that the protected circuit can tolerate this voltage level.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts listed are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the compliance status of the original SMCJ150CE3/TR13.

Q: Which substitute part has the highest current handling capability?

A: The 5.0SMDJ150CA from MDE Semiconductor Inc provides the highest peak pulse current (20.6A) and power dissipation (5000W) among all listed substitutes, suitable for high-energy transient suppression applications.

Q: Can SMLJ150CA be used as a direct replacement?

A: SMLJ150CA from Bourns Inc maintains the same electrical parameters as SMDJ150CA (12.4A peak pulse current, 3000W power rating) with identical reverse standoff and breakdown voltages. It is a valid substitute where higher current handling than the original part is acceptable. Highest inventory availability supports procurement.
