Product details
Overview
TPSMP6.8AHM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability overvoltage protection of low-voltage signal lines and power rails. It features a 6.45 V to 7.14 V breakdown voltage (VBR), 5.80 V stand-off voltage (VWM), 23.8 V clamping voltage at 10 A peak pulse current, 300 W peak pulse power rating, and AEC-Q101 qualification for automotive use.
For engineers reviewing the TPSMP6.8AHM3/84A datasheet, TPSMP6.8AHM3/84A pinout, TPSMP6.8AHM3/84A application, or TPSMP6.8AHM3/84A equivalent, key selection criteria include its 185 °C junction temperature capability, ultra-low profile (1.0 mm height), MSL Level 1 moisture sensitivity, and uni-directional polarity with cathode band marking - critical for ESD and surge protection in space-constrained automotive and industrial PCBs.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver fast response time (<1 ns), low incremental surge resistance, and excellent clamping performance under 10/1000 μs transients. Its junction passivation enables stable operation up to TJ = 185 °C, supporting under-hood automotive environments and high-power-density industrial modules.
The device operates exclusively in uni-directional mode, with forward conduction behavior defined by VF = 2.5 V at 25 A. It is not suitable for bi-directional or AC-line protection; design integration requires explicit attention to polarity alignment and thermal management on FR-4 PCBs using 5.0 mm × 5.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V - Ensures reliable turn-on before damage to downstream 5 V logic or microcontrollers |
| VWM | 5.80 V - Blocks normal 5 V rail operation while allowing safe margin below VBR |
| VC @ IPPM = 10 A | 23.8 V - Limits transient voltage seen by protected ICs during 300 W surge events |
| PPPM | 300 W - Sustains high-energy transients per ISO 7637-2 Pulse 1/2a/5a without degradation |
| TJ max | 185 °C - Enables placement near heat sources in automotive ECUs and motor drives |
| Package | DO-220AA (SMP) - 1.0 mm height supports ultra-thin designs; compatible with standard SMT reflow (260 °C peak) |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive semiconductor reliability (HTOL, TC, HTRB, etc.) |
Pinout & Package
TPSMP6.8AHM3/84A is a two-terminal surface-mount TVS diode in DO-220AA (SMP) package. Polarity is marked by a color band indicating the cathode terminal. The device has no active pins - only anode and cathode terminals aligned for standard pick-and-place placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to lower-potential side of protected line | Must be tied to GND or low-side rail when protecting positive-going transients on VCC/signal lines |
| Cathode | Current exit point in forward bias; marked with color band | Connected to protected node (e.g., MCU I/O, sensor output); conducts surge current to ground during overvoltage |

Yes, TPSMP6.8AHM3/84A is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials. It passes all stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated temperature-humidity stress (HAST), confirming suitability for automotive powertrain, chassis, and body electronics.
What is the maximum clamping voltage of TPSMP6.8AHM3/84A under surge conditions?
The TPSMP6.8AHM3/84A clamps to a maximum of 23.8 V at 10 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is verified per Fig. 1 and Table on page 2 of Vishay document 88471 and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Can TPSMP6.8AHM3/84A be used in automated SMT assembly processes?
