Product details
Overview
TPSMP6.8HE3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for automotive-grade overvoltage protection. It features 6.12 V minimum breakdown voltage (VBR), 7.48 V maximum VBR, 5.5 V stand-off voltage (VWM), 23.2 V clamping voltage (VC) at 1000 A peak pulse current, and 250 W peak pulse power (10/1000 µs waveform), used to safeguard sensor signal lines and drive transistors in automotive ECUs.
For engineers reviewing the TPSMP6.8HE3/84A datasheet, TPSMP6.8HE3/84A pinout, TPSMP6.8HE3/84A application, or TPSMP6.8HE3/84A equivalent, key selection criteria include AEC-Q101 qualification, low-profile 1.0 mm height, MSL Level 1 reflow compatibility, and verified clamping performance under 10/1000 µs surge conditions per ANSI/IEEE C62.35.
Technical Context
This TVS diode employs patented PAR oxide-passivated chip construction to achieve low incremental surge resistance and excellent clamping capability. Its unidirectional configuration enables precise reverse-biased protection of DC-coupled signal paths with fast response time and minimal leakage (≤300 µA at 5.5 V).
The device operates across -65 °C to +185 °C junction temperature range and is rated for 40 A non-repetitive forward surge current (IFSM). It meets RoHS 2002/95/EC and WEEE 2002/96/EC, with matte tin-plated leads compliant to J-STD-002 and JESD22-B102 solderability standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/5AT | Higher VWM (4.8 V), lower VC (11.2 V at 38.2 A), 400 W PPPM, SMA package (2.4 mm height) | Lower clamping voltage but higher profile; not AEC-Q101 qualified | Select when tighter clamping is critical and automotive qualification is not required |
| TPSMP6.8AHE3/84A | Higher VBR (6.45–7.14 V), same package, identical AEC-Q101 qualification and MSL Level 1 | Narrower VBR tolerance improves consistency in production across temperature | Choose for tighter parametric control in high-volume automotive production where VBR distribution matters |
Compared with SMAJ6.0A-E3/5AT, TPSMP6.8HE3/84A offers automotive qualification and lower profile but higher clamping voltage; versus TPSMP6.8AHE3/84A, it provides broader VBR tolerance at lower cost, suitable for less stringent design margins.

FAQ
What is the AEC-Q101 qualification status of the TPSMP6.8HE3/84A?
The TPSMP6.8HE3/84A is explicitly qualified to AEC-Q101 standards for automotive applications, as confirmed in the Vishay datasheet (Document Number 88471, Revision 21-Oct-08). This qualification covers stress tests including temperature cycling, humidity bias, and mechanical shock, ensuring reliability in under-hood and cabin environments. The HE3 suffix denotes high-reliability, automotive-grade construction, and the 84A packaging code indicates 7" tape-and-reel delivery.
Does the TPSMP6.8HE3/84A have a bidirectional or unidirectional configuration?
The TPSMP6.8HE3/84A is a unidirectional TVS diode, as stated in the "FEATURES" section of its datasheet. It functions as a reverse-biased avalanche diode, conducting only when the cathode voltage exceeds the anode by more than the breakdown threshold. This configuration is optimal for protecting DC-coupled signal lines where polarity is fixed, such as sensor outputs or MCU inputs referenced to ground.
What is the maximum clamping voltage of the TPSMP6.8HE3/84A under standard surge conditions?
The TPSMP6.8HE3/84A has a maximum clamping voltage (VC) of 23.2 V at 1000 A peak pulse current with a 10/1000 µs waveform, per the Electrical Characteristics table. This value is measured under standardized test conditions (TA = 25 °C, mounted on PCB with 5.0 × 5.0 mm copper pads) and defines the upper voltage limit imposed on protected circuitry during worst-case transients.
Is the TPSMP6.8HE3/84A compatible with lead-free reflow soldering processes?
Yes, the TPSMP6.8HE3/84A meets MSL Level 1 per J-STD-020 and supports lead-free reflow with a maximum peak temperature of 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD22-B102 solderability requirements, and the HE3 suffix confirms compliance with JESD201 Class 2 whisker resistance testing-ensuring long-term interconnect reliability in production assembly.
How does the DO-220AA (SMP) package of the TPSMP6.8HE3/84A compare to SMA or SMB packages in terms of height and thermal performance?
The DO-220AA (SMP) package of the TPSMP6.8HE3/84A has a typical height of 1.0 mm-significantly lower than SMA (2.4 mm) and SMB (2.3 mm) packages-enabling use in ultra-thin automotive modules. While its thermal resistance is higher than larger packages, the device's 2.5 W steady-state power dissipation (at TA = 75 °C on infinite heatsink) and 185 °C maximum junction temperature ensure adequate thermal margin when mounted on recommended 5.0 × 5.0 mm copper pads.
