5KP120CE3/TR13 Equivalent & Substitute Parts

Part Overview

The 5KP120CE3/TR13 is a transient voltage suppressor (TVS) diode manufactured by Microchip Technology, classified as a general-purpose bidirectional zener device. This through-hole component operates across a temperature range of -55°C to 175°C and is designed for transient voltage protection applications. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance parameters and mechanical compatibility are required due to inventory constraints, design optimization, or application-specific power handling requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP120CE3/TR13 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 120V
• Bidirectional Channels: 1
• Type: Zener
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C to 175°C minimum
• RoHS3 Compliance: Required
• Package / Case: P600 or R-6 Axial

Performance Parameters (Application-Dependent):

• Voltage - Breakdown (Min): 133V to 134V acceptable range
• Voltage - Clamping (Max) @ Ipp: 192.3V to 274V (higher values provide enhanced transient suppression)
• Current - Peak Pulse (10/1000µs): 23.5A minimum (higher ratings support increased power dissipation)
• Power - Peak Pulse: 5000W minimum (higher ratings available for demanding applications)

All identified substitute parts meet the mandatory compatibility criteria and maintain electrical performance within acceptable operating parameters for general-purpose transient voltage suppression applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Same Package, Equivalent Performance):

The 15KPA120CA and 30KPA120CA from MDE Semiconductor Inc are direct substitutes in the P600 axial package. Both maintain the 120V reverse standoff voltage and operate across the identical -55°C to 175°C temperature range. These parts are ROHS3 compliant with MSL 1 rating. The 15KPA120CA provides 3× the peak pulse power (15kW vs. 5kW) while the 30KPA120CA provides 6× the peak pulse power (30kW vs. 5kW), making them suitable for applications requiring enhanced transient suppression capability without package redesign.

Alternative Package Substitution:

The BZW50-120B from STMicroelectronics (TRANSIL™ series) is a functionally equivalent substitute with identical 120V reverse standoff voltage and 5000W peak pulse power rating. This part uses the R-6 axial package instead of P600. The BZW50-120B exhibits a higher clamping voltage (274V vs. 213V) and higher peak pulse current (219A vs. 23.5A) under different pulse conditions (8/20µs vs. 10/1000µs). This part is ROHS3 compliant with REACH Unaffected status. Package footprint differences require mechanical verification before implementation.

Compliance Verification:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. The 5KP120CE3/TR13 and BZW50-120B carry REACH Unaffected status, while the MDE Semiconductor parts require REACH status confirmation through the supplier. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Frequently Asked Questions (FAQ)

Q: Can the 15KPA120CA or 30KPA120CA be used as direct replacements for the 5KP120CE3/TR13?

A: Yes. Both MDE Semiconductor parts maintain identical reverse standoff voltage (120V), breakdown voltage range (134V), operating temperature (-55°C to 175°C), and P600 axial package configuration. The primary difference is increased peak pulse power handling (15kW and 30kW respectively vs. 5kW), which provides enhanced transient suppression without requiring circuit board modifications.

Q: What is the difference between the 5KP120CE3/TR13 and BZW50-120B?

A: Both parts share the same 120V reverse standoff voltage, 5000W peak pulse power rating, and ROHS3 compliance. The BZW50-120B uses an R-6 axial package instead of P600, resulting in different physical dimensions. The BZW50-120B exhibits higher clamping voltage (274V) and peak pulse current (219A) under 8/20µs pulse conditions, compared to the 5KP120CE3/TR13 specifications under 10/1000µs conditions. Package footprint compatibility must be verified before substitution.

Q: Are all substitute parts suitable for the same applications?

A: All substitute parts are classified for general-purpose transient voltage suppression with identical bidirectional zener topology and single-channel configuration. The 15KPA120CA and 30KPA120CA are suitable for applications requiring higher transient energy absorption. The BZW50-120B is suitable for applications where the R-6 package footprint is acceptable and higher clamping voltage performance is beneficial.

Q: What compliance certifications apply to these parts?

A: All parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The 5KP120CE3/TR13 and BZW50-120B carry REACH Unaffected status. The 15KPA120CA and 30KPA120CA require REACH status confirmation from MDE Semiconductor Inc. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Can the BZW50-120B be used in a circuit designed for the P600 package?

A: The BZW50-120B uses the R-6 axial package, which has different physical dimensions than the P600 package. Mechanical compatibility must be verified, including lead spacing, body diameter, and board layout constraints. Electrical substitution is valid, but physical installation requires design review.

Q: What is the difference in peak pulse current specifications between parts?

A: The 5KP120CE3/TR13 specifies 23.5A peak pulse current under 10/1000µs pulse conditions. The 15KPA120CA specifies 78.5A and the 30KPA120CA specifies 155.9A under identical 10/1000µs conditions. The BZW50-120B specifies 219A under different 8/20µs pulse conditions. These differences reflect the power dissipation capability of each device; higher current ratings indicate greater transient energy handling capacity.
