Product details
Overview
TPSMP6.8AHM3/85A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability automotive and industrial surge protection. It features 6.45 V to 7.14 V breakdown voltage (VBR), 10.5 V clamping voltage (VC) at 23.8 A peak pulse current (IPPM), and 300 W peak pulse power (PPPM) with 185 °C junction temperature rating.
For engineers reviewing the TPSMP6.8AHM3/85A datasheet, TPSMP6.8AHM3/85A pinout, TPSMP6.8AHM3/85A application, or TPSMP6.8AHM3/85A equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, low-profile 1.0 mm height, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on consumer, automotive, and industrial PCBs.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for fast response time and low incremental surge resistance. Its unidirectional configuration provides robust clamping during positive transients while blocking reverse leakage up to 5.80 V stand-off voltage (VWM) at ≤300 μA.
The device operates across -65 °C to +185 °C junction temperature range and meets JESD201 Class 2 whisker resistance. Its DO-220AA package enables high power density with thermal performance validated on 5.0 mm × 5.0 mm copper pads per terminal.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.8A | DO-214AC (SMA) package; 1.9 mm height; 200 W PPPM; VC = 11.2 V at 19.3 A | Lower power handling and taller profile limit use in ultra-thin automotive modules | Select when cost sensitivity outweighs space constraints and 300 W surge margin is not required |
| TPSMA6.8A | Same DO-220AA footprint but rated for 250 W PPPM; VC = 10.8 V at 23.2 A; non-AEC-Q101 | Lacks automotive qualification and 185 °C rating, restricting use to commercial/industrial environments | Choose for non-automotive designs where AEC-Q101 compliance is unnecessary and 300 W margin is optional |
Compared with SMAJ6.8A and TPSMA6.8A, the TPSMP6.8AHM3/85A delivers higher surge robustness (300 W vs. 200–250 W), lower profile (1.0 mm vs. 2.3 mm), and full AEC-Q101 qualification-making it the preferred choice for space-constrained, high-reliability automotive electronics requiring sustained 185 °C operation.

FAQ
What is the clamping voltage of the TPSMP6.8AHM3/85A under maximum surge conditions?
The TPSMP6.8AHM3/85A has a maximum clamping voltage (VC) of 10.5 V at 23.8 A peak pulse current (IPPM) using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures downstream components remain within safe voltage limits during standardized surge events. The TPSMP6.8AHM3/85A maintains this clamping performance across its full operating temperature range.
Is the TPSMP6.8AHM3/85A qualified for automotive applications?
Yes, the TPSMP6.8AHM3/85A is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and other high-reliability automotive environments. It also meets MSL Level 1 per J-STD-020 and passes JESD201 Class 2 whisker testing. The TPSMP6.8AHM3/85A is explicitly designated as automotive grade in Vishay's documentation.
What does the "HM3/85A" suffix indicate in TPSMP6.8AHM3/85A?
The "HM3" denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. The "85A" specifies the packaging: 13-inch diameter plastic tape and reel containing 10,000 units. This distinguishes it from "84A" (7-inch reel, 3000 units) and "H" or "I" variants with different reel sizes and quantities. The TPSMP6.8AHM3/85A is fully traceable and production-ready.
How does the TPSMP6.8AHM3/85A compare to standard SMA-package TVS diodes in terms of board space?
The TPSMP6.8AHM3/85A uses the DO-220AA (SMP) package with a typical height of 1.0 mm-less than half the 2.3 mm height of DO-214AC (SMA) devices like SMAJ6.8A. Its compact footprint and low profile enable denser layouts in modern automotive ECUs and portable electronics. The TPSMP6.8AHM3/85A achieves this without sacrificing surge rating, delivering 300 W versus 200 W for comparable SMA parts.
What is the maximum reverse leakage current of the TPSMP6.8AHM3/85A at its stand-off voltage?
At its 5.80 V stand-off voltage (VWM) and 25 °C ambient temperature, the TPSMP6.8AHM3/85A exhibits a maximum reverse leakage current (IR) of 300 μA. At elevated junction temperature (150 °C), leakage increases to 1000 μA-still within acceptable limits for most 5 V rail protection applications. This low leakage preserves system efficiency and avoids false triggering in always-on circuits. The TPSMP6.8AHM3/85A maintains these values across its qualified lifetime.
