Product details
Overview
TPSMP6.8AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the eSMP® Series, designed for high-reliability automotive and industrial circuit protection. It features a 6.45 V minimum breakdown voltage (VBR), 5.80 V stand-off voltage (VWM), 250 W peak pulse power (10/1000 µs), 185 °C maximum junction temperature, and SMP (DO-220AA) package with 1.0 mm typical height - deployed to safeguard sensor signal lines and drive transistors against ESD and surge events.
For engineers reviewing the TPSMP6.8AHM3_A/H datasheet, TPSMP6.8AHM3_A/H pinout, TPSMP6.8AHM3_A/H application, or TPSMP6.8AHM3_A/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, clamping performance at 23.8 V (IPPM), thermal derating behavior, and real-world use context for automotive-grade PCB-level transient suppression.
Technical Context
The TPSMP6.8AHM3_A/H employs passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), enabling effective clamping of ESD (IEC 61000-4-2) and lightning-induced surges (IEC 61000-4-5). Its unidirectional polarity and cathode-band marking support correct orientation during automated placement on FR-4 PCBs.
Rated for TJ = –65 °C to +185 °C operation and qualified to AEC-Q101, the device sustains 40 A non-repetitive forward surge current (IFSM) and maintains stable VBR with 0.057 %/°C temperature coefficient - critical for under-hood electronics where thermal cycling impacts long-term clamping consistency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V at 10 mA - defines precise voltage threshold at which clamping initiates under transient stress |
| VWM | 5.80 V - maximum continuous reverse voltage before leakage exceeds 300 μA, ensuring no false triggering in normal operation |
| IPPM | 23.8 A (10/1000 µs) - peak surge current it safely shunts while limiting voltage to ≤23.8 V |
| PPPM | 250 W (10/1000 µs) - transient energy-handling capacity for short-duration surges without failure |
| TJ max. | +185 °C - enables reliable operation in high-temperature automotive environments (e.g., engine control units) |
| Package | SMP (DO-220AA) - ultra-low-profile (1.0 mm height), MSL Level 1, halogen-free, RoHS-compliant surface-mount package |
| Polarity | Unidirectional - protects only against positive transients relative to cathode; requires correct orientation in series with protected line |
Pinout & Package
TPSMP6.8AHM3_A/H uses the SMP (DO-220AA) package: a two-terminal, surface-mount, unidirectional TVS diode with cathode identified by a color band. Dimensions are 3.61 mm × 2.18 mm × 1.0 mm (L × W × H), with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input side of protected line (e.g., signal source or power rail) | Connected to the node requiring transient protection; carries surge current into the device during overvoltage events |
| Cathode | Return path to ground or lower-potential reference | Marked by color band; must be tied to system ground or common return to complete clamping path and ensure proper conduction |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier process ensures stable VBR and low leakage across temperature and lifetime |
| AEC-Q101 qualification | Validated for automotive applications including engine control, ADAS sensors, and infotainment interfaces |
| Low profile (1.0 mm height) | Enables use in space-constrained modules such as camera ECUs and battery management systems |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow without preconditioning or special handling |
| Halogen-free & RoHS-compliant | Meets global environmental compliance requirements for automotive and industrial OEM supply chains |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting LIN bus or analog sensor outputs (e.g., pressure, temperature) in engine bay modules exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and microcontroller input to clamp transients before they reach sensitive ADC inputs. Use Value: Clamps 23.8 V at 23.8 A (10/1000 µs), preventing latch-up or damage to downstream MCU pins rated for ≤5.5 V logic levels. | Use Scenario: Safeguarding 24 V PLC digital input channels against field-wiring induced surges and inductive kickback from solenoid loads. IC Role / Device Role / Timing Role: Standoff-rated TVS mounted directly at connector entry point to divert surge energy before reaching optocoupler or level-shifter circuitry. Use Value: Withstands 40 A IFSM and operates up to +185 °C, supporting robust operation in uncooled industrial enclosures. |
| Consumer Power Adapter Input | Automotive Infotainment USB Line |
Use Scenario: Secondary-side surge protection on 5 V/12 V DC outputs of wall adapters subjected to AC line transients and ESD contact discharge. IC Role / Device Role / Timing Role: Fast-response TVS placed after DC-DC converter output filter to suppress residual spikes before reaching connected devices. Use Value: 250 W PPPM and 0.057 %/°C VBR TC ensure consistent clamping across ambient temperatures from –40 °C to +85 °C. | Use Scenario: ESD protection on USB 2.0 D+/D– lines in head unit or display modules, meeting IEC 61000-4-2 ±15 kV contact discharge. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed inline with data lines to limit voltage without distorting signal integrity. Use Value: Junction capacitance <100 pF at VWM (per typical curve Fig. 4) preserves USB 480 Mbps signaling fidelity. |
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 | Higher VBR (6.45–7.14 V same), but lower PPPM (400 W vs. 250 W), larger SMA package (2.5 mm height) | Less suitable for ultra-low-profile automotive modules; better for higher-energy industrial surges | Select SMAJ6.8A only when board height >2.0 mm is acceptable and surge energy exceeds 250 W capability |
| TPSMA6.8A | Same VBR/VWM, identical PPPM (250 W), but larger SMC (DO-214AB) package (2.6 mm height) | Not AEC-Q101 qualified; lacks automotive reliability validation and 185 °C rating | Choose TPSMA6.8A only for cost-sensitive consumer applications where AEC-Q101 and high-TJ are not required |
Compared with SMAJ6.8A and TPSMA6.8A, the TPSMP6.8AHM3_A/H uniquely combines AEC-Q101 qualification, 185 °C operation, and 1.0 mm height in a halogen-free SMP package - making it the only option validated for space-constrained, high-temperature automotive signal-line protection.

FAQ
What is the breakdown voltage tolerance for TPSMP6.8AHM3_A/H?
The TPSMP6.8AHM3_A/H has a specified breakdown voltage range of 6.45 V to 7.14 V at 10 mA test current (IT). This ±5% tolerance ensures predictable clamping onset across production lots and temperature extremes, critical for protecting 5 V logic interfaces without premature conduction during nominal operation.
Is TPSMP6.8AHM3_A/H suitable for bidirectional transient protection?
No, TPSMP6.8AHM3_A/H is strictly unidirectional. Its internal structure and polarity marking (cathode band) support clamping only positive transients relative to the cathode. For bidirectional protection, a separate device such as the SMBJ6.8CA or dual-diode array would be required - TPSMP6.8AHM3_A/H must not be used in AC-coupled or symmetrical surge scenarios.
Does TPSMP6.8AHM3_A/H meet automotive qualification standards?
Yes, TPSMP6.8AHM3_A/H is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature. It also meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 2 whisker testing - confirming suitability for under-hood and other demanding automotive electronic control units.
What is the maximum clamping voltage of TPSMP6.8AHM3_A/H at rated surge current?
At its rated peak pulse current of 23.8 A (10/1000 µs waveform), the TPSMP6.8AHM3_A/H clamps to a maximum of 23.8 V. This value is guaranteed per datasheet Figure 1 and Table "ELECTRICAL CHARACTERISTICS", ensuring downstream components see limited overvoltage during standardized surge events.
How does the SMP (DO-220AA) package of TPSMP6.8AHM3_A/H compare to SMA or SMC alternatives?
The SMP (DO-220AA) package of TPSMP6.8AHM3_A/H measures just 1.0 mm in height - significantly lower than SMA (2.5 mm) or SMC (2.6 mm) packages. This enables use in ultra-thin modules like ADAS cameras or compact battery monitors where vertical clearance is constrained, without sacrificing surge rating or thermal capability.
