Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMBJ82CA is determined by strict equivalence across the following electrical and mechanical parameters:

• Reverse standoff voltage within 70V to 70.1V range
• Breakdown voltage minimum of 77.8V to 77.9V
• Clamping voltage maximum of 113V at peak pulse current
• Peak pulse current of 5.3A to 5.4A
• Peak pulse power of 600W
• Package format: DO-214AA or SMB (surface mount)
• Bidirectional, single-channel Zener diode configuration
• Operating temperature range supporting minimum -55°C to 150°C

All identified substitute parts maintain these core electrical specifications and physical packaging requirements, ensuring functional interchangeability in the original application circuit.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: TPSMB82CA (Littelfuse Inc.)

The TPSMB82CA is the direct active equivalent from the original manufacturer. It maintains identical electrical specifications (70.1V standoff, 77.9V breakdown, 113V clamping, 5.4A peak pulse current) and package format. This part offers an extended operating temperature range (-65°C ~ 175°C) compared to the obsolete P6SMBJ82CA, providing enhanced thermal performance for demanding applications. ROHS3 compliance is maintained.

Secondary Selection: P6SMB82CA (Eaton - Electronics Division)

The P6SMB82CA provides exact electrical parameter matching with the original part (70.1V standoff, 77.9V breakdown, 113V clamping, 5.4A peak pulse current) and identical package specifications. Product status is active with RoHS compliance. Operating temperature range remains -55°C ~ 150°C, matching the original specification.

Alternative Selection: SMBJP6KE82CA-TP (Micro Commercial Co)

This part maintains full electrical equivalence (70.1V standoff, 77.9V breakdown, 113V clamping, 5.4A peak pulse current) with extended operating temperature range (-55°C ~ 175°C). ROHS3 compliance and active product status support long-term availability.

Extended Temperature Applications: SMBJ70CA or SMBJ70CAE3/TR13

For applications requiring extended temperature operation, SMBJ70CA (Semtech Corporation) or SMBJ70CAE3/TR13 (Microchip Technology) offer operating ranges to 175°C. These parts exhibit minor electrical variations (70V standoff, 77.8V breakdown, 5.3A peak pulse current) within acceptable tolerance for general-purpose TVS applications. Both maintain 113V clamping voltage and 600W peak pulse power specifications.

Frequently Asked Questions (FAQ)

Q: Can I directly replace P6SMBJ82CA with any of these substitute parts?

A: Yes, all listed substitute parts maintain the critical electrical parameters (70V to 70.1V standoff voltage, 77.8V to 77.9V breakdown voltage, 113V clamping voltage, 5.3A to 5.4A peak pulse current) and identical DO-214AA/SMB package format. Direct substitution is supported for general-purpose applications within the specified operating temperature ranges.

Q: What is the difference between the 70V and 70.1V standoff voltage parts?

A: The difference of 0.1V is within normal manufacturing tolerance for Zener diodes and does not affect functional interchangeability in circuit applications. Both voltage ratings provide equivalent clamping performance at 113V maximum.

Q: Does operating temperature range affect substitution compatibility?

A: Operating temperature range does not prevent substitution. Select parts based on your application's thermal requirements. TPSMB82CA, SMBJP6KE82CA-TP, SMBJ70CA, and SMBJ70CAE3/TR13 offer extended ranges (-65°C to 175°C) suitable for wider environmental conditions. The original P6SMBJ82CA specification (-55°C ~ 150°C) is maintained by P6SMB82CA and SMBJ70CAE3/TR13.

Q: Are all substitute parts RoHS compliant?

A: Yes, all substitute parts listed are RoHS compliant (either RoHS or ROHS3 status). This ensures compatibility with modern manufacturing and environmental regulations.

Q: What packaging options are available?

A: All substitute parts are supplied in DO-214AA (SMB) surface-mount package format. Tape & Reel (TR) packaging is available for most parts, supporting automated assembly processes.

Q: Which substitute offers the best long-term availability?

A: TPSMB82CA (Littelfuse Inc.) and SMBJP6KE82CA-TP (Micro Commercial Co) show the highest inventory levels (2400 and 17300 units respectively) and active product status, supporting sustained procurement. P6SMB82CA (Eaton) offers 30100 units in stock.
