P6SMBJ200C Equivalent & Substitute Parts

Part Overview

The P6SMBJ200C is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage clamping applications. This bidirectional Zener diode operates with a reverse standoff voltage of 171V and provides peak pulse clamping at 287.7V with a peak pulse current of 2.2A. The device is packaged in DO-214AA (SMB) surface mount configuration and rated for 600W peak pulse power dissipation across an operating temperature range of -55°C to 150°C.

The P6SMBJ200C is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMBJ200C are qualified based on the following critical parameters that determine functional equivalence:

• Reverse standoff voltage: 171V (Typ)
• Breakdown voltage minimum: 180V or higher
• Clamping voltage maximum @ Ipp: within acceptable range for the application
• Peak pulse current: 2.2A or compatible
• Power dissipation: 600W peak pulse
• Package type: DO-214AA / SMB surface mount
• Bidirectional channels: 1
• Operating temperature range: -55°C minimum to 150°C or higher

Substitute parts are grouped into two categories based on clamping voltage performance:

Group 1 (Lower Clamping Voltage): Parts with clamping voltage at 274V, providing tighter voltage regulation compared to the original part.

Group 2 (Higher Clamping Voltage): Parts with clamping voltage at 353V, offering higher transient energy absorption capability.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing status, providing superior supply chain availability compared to the obsolete P6SMBJ200C. Selection among substitutes depends on application-specific clamping voltage requirements:

SMBJP6KE200CA-TP, P6SMB200CA, and TVP06B201CA-G are direct functional equivalents with clamping voltage at 274V, which is lower than the original part's 287.7V. These parts provide tighter voltage regulation and are suitable for applications where lower clamping voltage is acceptable or beneficial. All three maintain the same reverse standoff voltage (171V), peak pulse current (2.2A), and power dissipation (600W). SMBJP6KE200CA-TP offers extended operating temperature to 175°C.

SM6T200CA provides higher clamping voltage at 353V with significantly increased peak pulse current capability (11.3A at 8/20µs pulse). This part is suitable for applications requiring greater transient energy absorption. The higher clamping voltage may be necessary in circuits where the original 287.7V specification is critical.

All substitute parts comply with RoHS3 or equivalent environmental standards and maintain the DO-214AA (SMB) surface mount package configuration, ensuring mechanical and thermal compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can I directly replace P6SMBJ200C with any of the listed substitutes?

A: Direct replacement depends on your circuit's clamping voltage tolerance. SMBJP6KE200CA-TP, P6SMB200CA, and TVP06B201CA-G have lower clamping voltage (274V vs. 287.7V) and are suitable if your design accepts this specification. SM6T200CA has higher clamping voltage (353V) and should be selected only if higher transient energy absorption is required or if the original 287.7V specification is not critical.

Q: What is the difference between the substitute parts?

A: The primary differences are manufacturer, clamping voltage, and peak pulse current. SMBJP6KE200CA-TP, P6SMB200CA, and TVP06B201CA-G are functionally equivalent with 274V clamping and 2.2A peak pulse current. SM6T200CA differs with 353V clamping and 11.3A peak pulse current. SMBJP6KE200CA-TP offers extended temperature range to 175°C.

Q: Are all substitutes available in the same package?

A: Yes, all substitute parts use the DO-214AA (SMB) surface mount package, ensuring identical PCB footprint and mounting compatibility. Packaging formats differ (Tape & Reel vs. Cut Tape), but this affects procurement and handling only, not electrical or mechanical performance.

Q: Which substitute should I choose for a new design?

A: For new designs, P6SMB200CA (Eaton) or SMBJP6KE200CA-TP (Micro Commercial Co) are recommended as primary choices due to active product status and established supply chains. If your application requires higher transient energy absorption, SM6T200CA (STMicroelectronics) is the appropriate selection.

Q: Do all substitutes meet the same environmental compliance standards?

A: Yes, all substitute parts are ROHS3 compliant or equivalent, meeting current environmental regulations. Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special storage or handling requirements.
