Substitute Part Grouping Explanation
Substitution of the 30KP36A-TP is determined by the following critical electrical and mechanical parameters:
Primary Substitution Criteria:
- Voltage - Reverse Standoff: 36V (exact match required)
- Voltage - Breakdown (Min): 40.2V (exact match required)
- Voltage - Clamping (Max) @ Ipp: 61.8V (exact match required)
- Unidirectional Channels: 1 (exact match required)
- Mounting Type: Through Hole (exact match required)
- Package / Case: Axial configuration (exact match required)
- Type: Zener (exact match required)
Secondary Substitution Criteria:
- Power - Peak Pulse: 30000W (30kW) for direct equivalents; lower ratings acceptable for reduced power applications
- Operating Temperature Range: -55°C ~ 175°C (TJ) or wider range acceptable
- RoHS Status: ROHS3 Compliant preferred
- Product Status: Active required
Substitute parts are grouped into two categories:
Direct Equivalents (30KPA Series): Parts 30KPA36A and 30KPA36A-B match all critical electrical parameters and peak pulse power rating. These differ only in packaging format (Bulk vs. Tape & Reel) and manufacturer.
Functional Equivalents (Lower Power Ratings): Parts 15KPA36A and 5KP36A series maintain identical voltage specifications but feature reduced peak pulse power ratings (15kW and 5kW respectively). These are suitable for applications with lower transient energy requirements.

Engineering Selection Recommendations
For Direct Replacement (30kW Peak Pulse Power Required):
Select 30KPA36A or 30KPA36A-B when the application demands the full 30kW peak pulse power rating and identical voltage clamping characteristics. Both parts maintain the 36V reverse standoff voltage and 61.8V maximum clamping voltage. The 30KPA36A-B from Littelfuse Inc. is REACH Unaffected, while the 30KPA36A from MDE Semiconductor Inc. has REACH information available upon request. Both are active products with ROHS3 compliance.
For Reduced Power Applications (15kW Peak Pulse Power):
The 15KPA36A from MDE Semiconductor Inc. is suitable when transient energy levels are lower. This part maintains the 36V reverse standoff voltage but features a 59.8V maximum clamping voltage and 15kW peak pulse power rating. Product status is active with ROHS3 compliance.
For Low-Power Applications (5kW Peak Pulse Power):
The 5KP36A from Diotec Semiconductor or 5KP36A-E3/54 from Vishay General Semiconductor are appropriate for circuits with minimal transient energy requirements. Both maintain the 36V reverse standoff voltage with 58.1V maximum clamping voltage and 5kW peak pulse power rating. The Vishay part (5KP36A-E3/54) offers the widest operating temperature range (-55°C ~ 175°C) and is available in Cut Tape packaging. Both are active, ROHS3-compliant products.
Compliance Considerations:
All substitute parts listed are active products with ROHS3 compliance. The 30KPA36A-B and 5KP36A-E3/54 have confirmed REACH Unaffected status, providing regulatory clarity for international applications.
Frequently Asked Questions (FAQ)
Q: Can I use a 15KPA36A or 5KP36A in place of the 30KP36A-TP?
A: Yes, if your circuit can tolerate lower peak pulse power dissipation. The 15KPA36A handles 15kW and the 5KP36A handles 5kW, compared to the 30KP36A-TP's 30kW rating. All maintain the same 36V reverse standoff voltage. Verify that your transient energy levels do not exceed the substitute part's power rating.
Q: What is the difference between the R-6 and P600 package designations?
A: Both are axial through-hole packages for TVS diodes. The R-6 and P600 are different mechanical package styles from various manufacturers. Electrical performance is equivalent; physical dimensions may differ slightly. Verify PCB footprint compatibility before substitution.
Q: Are the 30KPA36A and 30KPA36A-B interchangeable?
A: Yes. Both parts are direct electrical equivalents with identical voltage and power specifications. The primary difference is manufacturer (MDE Semiconductor Inc. vs. Littelfuse Inc.) and packaging format (Bulk vs. Bulk). Both are active, ROHS3-compliant products.
Q: Which substitute part has the best regulatory compliance documentation?
A: The 30KPA36A-B (Littelfuse) and 5KP36A-E3/54 (Vishay) both have confirmed REACH Unaffected status. For applications requiring strict regulatory traceability, these parts provide the clearest compliance documentation.
Q: Can I use the 5KP36A-E3/54 in high-temperature environments?
A: Yes. The 5KP36A-E3/54 operates across -55°C to 175°C (TJ), matching the temperature range of the main part. However, its 5kW power rating limits its use to low-energy transient applications.
Q: What inventory levels are available for each substitute?
A: 30KPA36A: 1842 pcs; 30KPA36A-B: 1094 pcs; 15KPA36A: 1167 pcs; 5KP36A: 4120 pcs; 5KP36A-E3/54: 8200 pcs. The 5KP36A-E3/54 has the highest stock availability.
