P6SMBJ62 Equivalent & Substitute Parts

Part Overview

The P6SMBJ62 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage protection in surface-mount applications. This component features a 53V reverse standoff voltage with an 89.25V maximum clamping voltage and 7.2A peak pulse current capability in a DO-214AA (SMBJ) package.

The P6SMBJ62 is classified as obsolete. Equivalent substitute parts are available from active manufacturers to maintain design continuity and ensure supply chain availability for new production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMBJ62 is determined by the following critical electrical and mechanical parameters:

• Reverse standoff voltage: 53V (Typ)
• Breakdown voltage minimum: 55.8V or higher
• Clamping voltage maximum: within acceptable range for circuit protection
• Peak pulse current: 7.2A or higher
• Peak pulse power: 600W
• Package type: DO-214AA (SMB) surface mount
• Unidirectional configuration: single channel
• Operating temperature range: -55°C to 150°C

The P6SMB62A from Thinking Electronics Industrial Co. meets these substitution criteria with compatible electrical characteristics and identical package specifications.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB62A is an active substitute for the obsolete P6SMBJ62. Both components maintain identical reverse standoff voltage (53V) and operating temperature range (-55°C to 150°C). The P6SMB62A demonstrates higher breakdown voltage (58.9V minimum versus 55.8V) and lower clamping voltage (85V versus 89.25V), both of which represent acceptable performance variations within the TVS diode classification.

Both parts are RoHS compliant with MSL rating of 1 (Unlimited), ensuring compatibility with modern manufacturing and environmental standards. The P6SMB62A is available in active production status with established supply chain availability, making it the appropriate selection for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB62A directly replace the P6SMBJ62 in existing designs?

A: Yes. Both components share identical reverse standoff voltage (53V), peak pulse power (600W), package type (DO-214AA, SMB), and operating temperature range. The electrical parameter variations fall within acceptable substitution tolerances for TVS diode applications.

Q: What is the difference in clamping voltage between these parts?

A: The P6SMBJ62 has a maximum clamping voltage of 89.25V, while the P6SMB62A clamps at 85V maximum. This 4.25V difference represents improved clamping performance in the substitute part and does not compromise circuit protection.

Q: Are there packaging differences between these parts?

A: Both parts use the DO-214AA (SMB) surface-mount package. The P6SMBJ62 is supplied in standard packaging, while the P6SMB62A is available in Tape & Reel (TR) format, which is standard for high-volume production environments.

Q: What is the product status difference?

A: The P6SMBJ62 is classified as obsolete, while the P6SMB62A is in active production. This makes the P6SMB62A the recommended choice for new designs and ongoing production requirements.

Q: Are both parts RoHS compliant?

A: Yes. The P6SMBJ62 is ROHS3 compliant, and the P6SMB62A is RoHS compliant. Both meet current environmental and regulatory requirements for electronic component manufacturing.
