TPSMP6.8HM3/84A Equivalent & Substitute Parts

Part Overview

The TPSMP6.8HM3/84A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component is designed for transient overvoltage protection in surface mount applications, featuring a 5.5V reverse standoff voltage and 10.8V maximum clamping voltage. The part is classified as obsolete, making identification of active equivalent components essential for ongoing production and design continuity. Substitute parts must maintain electrical performance within the specified parameter ranges while offering current availability and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPSMP6.8HM3/84A is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 5.5V nominal tolerance
• Voltage - Clamping (Max) @ Ipp: 10.8V maximum tolerance
• Current - Peak Pulse (10/1000µs): 23.2A minimum capability
• Power - Peak Pulse: 250W minimum rating
• Operating Temperature Range: -65°C to 185°C (TJ)

Mechanical & Compliance Criteria:

• Package / Case: DO-220AA (SMP) surface mount
• Mounting Type: Surface Mount
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute part TPSMP6.8AHM3_A/H meets these criteria with minor parameter variations within acceptable engineering tolerances for TVS diode applications.

Parameter Comparison

Engineering Selection Recommendations

The TPSMP6.8AHM3_A/H is the direct substitute for the obsolete TPSMP6.8HM3/84A. Both components share identical automotive grade qualification (AEC-Q101), RoHS3 compliance, and MSL rating. The substitute maintains the same package footprint (DO-220AA SMP), operating temperature range (-65°C to 185°C TJ), and power rating (250W peak pulse).

The electrical parameter variations between the two parts fall within acceptable tolerances for TVS diode applications:

• Reverse standoff voltage increases from 5.5V to 5.8V
• Clamping voltage decreases from 10.8V to 10.5V
• Peak pulse current increases from 23.2A to 23.8A

The TPSMP6.8AHM3_A/H offers the advantage of active product status with substantial inventory availability (165,300 pcs), compared to the obsolete status of the original part (1,107 pcs remaining stock). Selection of the substitute part ensures long-term supply chain continuity and compliance with current automotive qualification standards.

Frequently Asked Questions (FAQ)

Q: Can TPSMP6.8AHM3_A/H be used as a direct replacement for TPSMP6.8HM3/84A?

A: Yes. Both parts are unidirectional TVS diodes with identical package geometry (DO-220AA SMP), mounting type (surface mount), and automotive qualification (AEC-Q101). Electrical parameters are within acceptable tolerance ranges for TVS applications.

Q: What are the key electrical differences between these parts?

A: The substitute part has a slightly higher reverse standoff voltage (5.8V vs 5.5V), lower maximum clamping voltage (10.5V vs 10.8V), and marginally higher peak pulse current capability (23.8A vs 23.2A). These variations are typical within the PAR® and eSMP® series and do not affect functional compatibility.

Q: Are there packaging differences?

A: The original part is supplied in standard packaging, while the substitute (TPSMP6.8AHM3_A/H) is available in Tape & Reel (TR) format. Both use the identical DO-220AA (SMP) surface mount package case, ensuring PCB footprint compatibility.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both components carry Automotive grade classification and AEC-Q101 qualification. Both are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current automotive supply chain requirements.

Q: Why is the original part listed as obsolete?

A: The TPSMP6.8HM3/84A has been discontinued by the manufacturer. The TPSMP6.8AHM3_A/H represents the active equivalent within the same product series, offering identical electrical performance and compliance characteristics.
