5KP200-B Equivalent & Substitute Parts

Part Overview

The 5KP200-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage clamping applications. This unidirectional Zener diode features a 200V reverse standoff voltage and 345.66V maximum clamping voltage with 5000W peak pulse power handling. The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Substitute parts maintain the core electrical specifications while offering improved availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 5KP200-B is determined by the following critical parameters:

• Voltage - Reverse Standoff: Must equal 200V
• Mounting Type: Must be Through Hole
• Operating Temperature Range: Must support -55°C ~ 175°C (TJ)
• Power - Peak Pulse: Minimum 5000W (5kW)
• Type: Zener diode, unidirectional

Substitute parts are grouped into two categories based on power rating and package compatibility:

Category A (5kW Power Rating): 5KP200A, 5KP200A-B, and 5KP200A-TP maintain the original 5000W peak pulse power specification with improved clamping voltage characteristics (329.2V) and active product status.

Category B (15kW Power Rating): 15KP200A-TP and 15KPA200AE3/TR13 provide enhanced power handling (15000W) with comparable voltage specifications, suitable for applications requiring higher transient energy absorption.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Same Power Rating)

The 5KP200A and 5KP200A-B are direct functional equivalents to the 5KP200-B, maintaining the 5000W peak pulse power specification and P600 axial package. Both parts are manufactured by Littelfuse Inc. with active product status and ROHS3 compliance. The 5KP200A is available in Cut Tape packaging, while 5KP200A-B is supplied in Bulk. These parts feature improved clamping voltage performance (329.2V versus 345.66V) and specified peak pulse current (15.5A), providing superior transient suppression characteristics.

Alternative Suppliers (Same Power Rating)

The 5KP200A-TP from Micro Commercial Co provides equivalent electrical performance with 5000W power handling and active product status. This part uses the R-6 axial package instead of P600, requiring PCB layout verification for mechanical compatibility. ROHS3 compliance and identical operating temperature range ensure regulatory and thermal compatibility.

Enhanced Power Handling Options

The 15KP200A-TP (Micro Commercial Co) and 15KPA200AE3/TR13 (Microchip Technology) offer 15000W peak pulse power, providing threefold energy absorption capability. Both maintain the 200V reverse standoff voltage and active product status. The 15KPA200AE3/TR13 features the P600 package matching the original design, while 15KP200A-TP uses the R-6 package. These options are suitable for applications requiring enhanced transient protection margins.

Frequently Asked Questions (FAQ)

Q: Can 5KP200A directly replace 5KP200-B without circuit modifications?

A: Yes. The 5KP200A maintains identical reverse standoff voltage (200V), operating temperature range (-55°C ~ 175°C), and power rating (5000W). Both use P600 axial through-hole packages. The improved clamping voltage (329.2V versus 345.66V) provides better transient suppression performance.

Q: What is the difference between 5KP200A and 5KP200A-B?

A: Both parts are electrically identical. The difference is packaging: 5KP200A is supplied in Cut Tape (CT), while 5KP200A-B is supplied in Bulk. Select based on procurement and assembly requirements.

Q: Can I use 15KP200A-TP or 15KPA200AE3/TR13 as substitutes?

A: Yes, both are compatible substitutes with enhanced power handling (15000W versus 5000W). The 15KPA200AE3/TR13 maintains the P600 package; the 15KP200A-TP uses R-6 package. Verify PCB layout compatibility for the R-6 package variant. These parts provide superior transient energy absorption for demanding applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitutes (5KP200A, 5KP200A-B, 5KP200A-TP, 15KP200A-TP, and 15KPA200AE3/TR13) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the impact of different package types (P600 versus R-6)?

A: P600 and R-6 are both axial through-hole packages with different physical dimensions. Verify PCB footprint compatibility before selecting parts with different package designations. The 5KP200A and 15KPA200AE3/TR13 use P600; the 5KP200A-TP and 15KP200A-TP use R-6.

Q: Why is the clamping voltage lower in substitute parts?

A: Substitute parts feature improved clamping voltage performance (lower values indicate better transient suppression). The 5KP200A series clamps at 329.2V, and the 15KPA200AE3/TR13 clamps at 319.1V, compared to the original 345.66V. Lower clamping voltages provide enhanced circuit protection.
