- Package / Case: DO-214AB (SMC)
- Mounting Type: Surface Mount
- Type: Zener, Bidirectional, Single Channel
- RoHS Status: ROHS3 Compliant
- Moisture Sensitivity Level (MSL): 1 (Unlimited)
Substitute parts are grouped into two categories based on peak pulse current and power dissipation:
Direct Equivalents (1500W Class): Parts with 6.2A peak pulse current and 1500W power rating, providing identical electrical performance.
Higher Performance Alternatives (3000W-5000W Class): Parts with increased peak pulse current (12.4A to 20.6A) and proportionally higher power ratings (3000W to 5000W), suitable for applications requiring enhanced transient energy absorption while maintaining identical voltage parameters and package compatibility.

Engineering Selection Recommendations
Direct Replacement (Identical Electrical Performance):
SMCJ150CA (Meritek), SMCJ150CA-HR (Littelfuse Inc.), SMCJ150CA-HRA (Littelfuse Inc.), SMCJ150CA-HRAT7 (Littelfuse Inc.), and SMCJ150CA-TP (Micro Commercial Co) provide equivalent 1500W performance with matching 6.2A peak pulse current specifications. All are active products with ROHS3 compliance. Littelfuse variants offer extended lower temperature operation to -65°C compared to the original -55°C minimum. SMCJ150CA-TP supports extended upper temperature operation to 175°C.
Higher Performance Alternatives:
SMDJ150CA (Alpha & Omega Semiconductor Inc.) provides 3000W capability with 12.4A peak pulse current while maintaining identical voltage parameters and package compatibility. 5.0SMDJ150CA (MDE Semiconductor Inc.) and 5.0SMLJ150CA-TP (Micro Commercial Co) deliver 5000W performance with 20.6A peak pulse current. These higher-rated alternatives are suitable for applications requiring increased transient energy absorption without circuit redesign. 5.0SMLJ150CA-TP extends operating temperature to 175°C.
All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and DO-214AB (SMC) package compatibility with the original CD214C-T150CALF.
Frequently Asked Questions (FAQ)
Q: Can SMCJ150CA directly replace CD214C-T150CALF?
A: Yes. SMCJ150CA matches all critical electrical parameters: 150V reverse standoff, 243V clamping voltage, 6.2A peak pulse current, and 1500W power rating. Both use DO-214AB (SMC) packaging and are ROHS3 compliant with MSL Level 1 rating.
Q: What is the difference between 1500W and 5000W rated parts?
A: Peak pulse current and power dissipation capacity differ. The original CD214C-T150CALF and direct equivalents handle 6.2A at 1500W. Higher-rated alternatives (SMDJ150CA at 3000W, 5.0SMDJ150CA at 5000W) handle proportionally higher transient currents (12.4A and 20.6A respectively) while maintaining identical voltage clamping characteristics. Selection depends on application transient energy requirements.
Q: Are all substitutes available in the same packaging?
A: Yes. All listed substitutes use DO-214AB (SMC) surface mount packaging, ensuring mechanical and thermal compatibility with existing PCB layouts and assembly processes.
Q: Which substitute offers the widest operating temperature range?
A: SMCJ150CA-TP and 5.0SMLJ150CA-TP both support -55°C to 175°C operation, extending the upper temperature limit by 25°C compared to the original -55°C to 150°C specification.
Q: Are all substitutes ROHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (unlimited) moisture sensitivity rating, matching the original part's environmental and regulatory status.
Q: Can I use a 5000W rated part in place of the 1500W original?
A: Yes. Higher power-rated parts (5.0SMDJ150CA, 5.0SMLJ150CA-TP) maintain identical voltage parameters and package compatibility. They provide enhanced transient protection capability without requiring circuit modifications. Selection should be based on application transient energy requirements and thermal management considerations.
