Product details
Overview
TPSMP6.8AHE3/85A 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 6.45 V to 7.14 V breakdown voltage (VBR), 23.8 V clamping voltage (VC) at 1000 A peak pulse current, and 300 W peak pulse power rating with 10/1000 µs waveform - used to safeguard sensor signal lines and drive transistors in harsh automotive environments.
For engineers reviewing the TPSMP6.8AHE3/85A datasheet, TPSMP6.8AHE3/85A pinout, TPSMP6.8AHE3/85A application, or TPSMP6.8AHE3/85A equivalent, key selection criteria include AEC-Q101 qualification, low-profile 1.0 mm height, RoHS-compliant matte tin terminals, and verified clamping performance under ISO 7637-2 surge conditions.
Technical Context
This TVS diode employs Vishay's patented PAR oxide-passivated chip construction, enabling low incremental surge resistance and fast response time (<1 ns). Its unidirectional configuration provides reverse-biased clamping only, with forward voltage of 2.5 V at 25 A and maximum junction temperature of +185 °C.
The device operates within -65 °C to +185 °C junction range, meets MSL Level 1 per J-STD-020 (260 °C reflow peak), and is rated for 40 A non-repetitive forward surge current (IFSM). Thermal derating follows Fig. 2 in the datasheet, with 2.5 W steady-state power dissipation on infinite heatsink at 75 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V - defines precise voltage threshold at which clamping initiates under 10 mA test current |
| VC @ IPPM | 23.8 V at 1000 A - maximum clamped voltage during 10/1000 µs surge, limiting stress on downstream ICs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.8A | DO-214AC (SMA) package; 200 W PPPM; higher VC = 11.5 V at 32.4 A; no AEC-Q101 qualification | General industrial/commercial use only; not validated for automotive temperature cycling or humidity testing | Select SMAJ6.8A only for cost-sensitive non-automotive designs where 1.0 mm height and AEC-Q101 are not required. |
| TPSMA6.8A | Same DO-220AA footprint but lower PPPM = 200 W; identical VBR range and AEC-Q101 qualification | Lower surge margin suitable for sub-100 A transient environments such as interior lighting or HVAC controls | Choose TPSMA6.8A when system-level surge testing confirms ≤200 W requirements and board space allows same footprint. |
Compared with SMAJ6.8A and TPSMA6.8A, the TPSMP6.8AHE3/85A delivers higher 300 W surge capacity in the same ultra-low-profile DO-220AA package with full AEC-Q101 validation - making it the preferred choice for under-hood and safety-critical automotive nodes requiring robust, space-efficient clamping.

FAQ
What is the breakdown voltage range of the TPSMP6.8AHE3/85A?
The TPSMP6.8AHE3/85A has a guaranteed breakdown voltage (VBR) range of 6.45 V to 7.14 V at 10 mA test current, measured per ANSI/IEEE C62.35 standards. This tight tolerance ensures consistent clamping initiation across production lots and supports precise design margins in automotive sensor interfaces where overvoltage thresholds must remain stable over temperature and lifetime.
Is the TPSMP6.8AHE3/85A qualified for automotive applications?
Yes, the TPSMP6.8AHE3/85A is AEC-Q101 qualified and designated as high-reliability/automotive grade (suffix "A"). It undergoes rigorous stress testing including temperature cycling, humidity bias, and high-temperature operating life - validating its suitability for under-hood and safety-critical systems such as engine control units and ADAS sensor modules.
What is the clamping voltage of the TPSMP6.8AHE3/85A at its rated surge current?
The TPSMP6.8AHE3/85A clamps to a maximum of 23.8 V at 1000 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 and Table 1 in Vishay document 88471 and directly determines the maximum voltage stress imposed on downstream ICs during surge events.
Does the TPSMP6.8AHE3/85A have a unidirectional or bidirectional configuration?
The TPSMP6.8AHE3/85A is a unidirectional TVS diode, meaning it clamps only in reverse bias above VBR and conducts forward current like a standard diode below VF. Its polarity is marked by a cathode band, and it is not intended for AC or bipolar transient suppression - unlike bidirectional variants such as TPSMP6.8CA.
What package type does the TPSMP6.8AHE3/85A use, and what are its key mechanical attributes?
The TPSMP6.8AHE3/85A uses the DO-220AA (SMP) package: a surface-mount, low-profile case with 1.0 mm typical height, 0.142 inch (3.61 mm) length, and 0.126 inch (3.19 mm) width. Its matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance, supporting automated placement and lead-free reflow.
