TPSMB8.2A/1 Equivalent & Substitute Parts

Part Overview

The TPSMB8.2A/1 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 7.02V reverse standoff voltage range with a 12.1V maximum clamping voltage and 49.6A peak pulse current rating. The device is designed for general-purpose transient voltage suppression applications and is currently in active production status. Substitute parts are identified based on matching electrical characteristics within the allowed parameter tolerances for TVS diodes in the DO-214AA (SMB) package category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPSMB8.2A/1 are qualified based on the following electrical and mechanical criteria:

Primary Matching Criteria:

• Reverse standoff voltage within 6.5V to 7.02V range
• Clamping voltage (Max) between 11.2V and 12.1V
• Peak pulse current rating of 50A or greater
• Peak pulse power rating of 600W
• DO-214AA (SMB) surface mount package
• Unidirectional Zener diode configuration
• General-purpose application classification

Secondary Considerations:

• Product status: Active production
• Moisture sensitivity level: MSL 1 (Unlimited)
• RoHS and REACH compliance status
• Operating temperature range compatibility

All identified substitutes maintain electrical equivalence within the specified parameter windows while preserving package and mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

P6SMB8.2A (Taiwan Semiconductor Corporation): This substitute provides the closest electrical match to the TPSMB8.2A/1, with identical reverse standoff voltage (7.02V) and clamping voltage (12.1V). Peak pulse current is rated at 52A, exceeding the original specification. The part is ROHS3 compliant and available in high volume (3400 pcs). Operating temperature range is -55 to 150°C, which is narrower than the original but suitable for most general-purpose applications.

SMBJ6.5A-TR (STMicroelectronics): This substitute operates at a lower reverse standoff voltage (6.5V) and clamping voltage (11.2V) compared to the TPSMB8.2A/1. Peak pulse current is rated at 56A. ROHS3 compliance and high inventory availability (10400 pcs) are confirmed. Operating temperature range is -55 to 150°C. Selection of this part requires verification that the lower voltage thresholds are acceptable for the target application.

SMBJ7.0A (MDD): This substitute provides reverse standoff voltage of 7V and clamping voltage of 12V, closely matching the original specification. Peak pulse current is rated at 50A. ROHS3 compliance is confirmed with high inventory (15665 pcs). Operating temperature range is -50 to 150°C, which is narrower than the original.

SMBJ7.0A-TP (Micro Commercial Co): This substitute offers reverse standoff voltage of 7V and clamping voltage of 12V, with peak pulse current rated at 50A. ROHS3 compliance is confirmed with high inventory availability (15300 pcs). Operating temperature range is -55 to 175°C, providing extended high-temperature capability compared to the original specification.

Frequently Asked Questions (FAQ)

Q: What determines if a TVS diode can substitute for the TPSMB8.2A/1?

A: Substitution is based on matching the reverse standoff voltage (within 6.5V to 7.02V), clamping voltage (11.2V to 12.1V), peak pulse current (50A or greater), and maintaining the DO-214AA (SMB) surface mount package. All substitute parts must be unidirectional Zener diodes rated for 600W peak pulse power.

Q: Are all substitute parts pin-compatible with the TPSMB8.2A/1?

A: Yes. All identified substitutes use the DO-214AA (SMB) package, which provides identical pinout and footprint compatibility. Direct board-level substitution is possible without PCB redesign.

Q: What is the difference between the TPSMB8.2A/1 and P6SMB8.2A?

A: The P6SMB8.2A provides identical electrical specifications (7.02V standoff, 12.1V clamping) with slightly higher peak pulse current (52A vs 49.6A). The primary difference is RoHS compliance status: P6SMB8.2A is ROHS3 compliant while TPSMB8.2A/1 is non-compliant. Operating temperature range is narrower for the P6SMB8.2A (-55 to 150°C vs -65 to 185°C).

Q: Can I use SMBJ6.5A-TR as a direct replacement?

A: SMBJ6.5A-TR operates at lower voltage thresholds (6.5V standoff, 11.2V clamping) compared to the TPSMB8.2A/1 (7.02V standoff, 12.1V clamping). This part is suitable only if your circuit design tolerates lower voltage suppression levels. Peak pulse current (56A) exceeds the original specification.

Q: Which substitute offers the widest operating temperature range?

A: SMBJ7.0A-TP provides the widest operating temperature range (-55 to 175°C) among the identified substitutes, extending 10°C above the original TPSMB8.2A/1 specification (-65 to 185°C) at the high end but narrower at the low end.

Q: Are all substitutes RoHS compliant?

A: No. The original TPSMB8.2A/1 is RoHS non-compliant. All identified substitutes (P6SMB8.2A, SMBJ6.5A-TR, SMBJ7.0A, SMBJ7.0A-TP) are ROHS3 compliant.

Q: What is the inventory status of these substitutes?

A: All substitutes are in active production with confirmed stock availability: P6SMB8.2A (3400 pcs), SMBJ6.5A-TR (10400 pcs), SMBJ7.0A (15665 pcs), SMBJ7.0A-TP (15300 pcs).
