Product details
Overview
TPSMP6.8AHM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for high-reliability automotive and industrial circuit protection. It features a 6.45 V minimum breakdown voltage (VBR), 5.8 V stand-off voltage (VWM), 250 W peak pulse power (10/1000 µs), 185 °C maximum junction temperature, and SMP (DO-220AA) surface-mount package. It protects signal lines and drive transistors in automotive ECUs and sensor interfaces.
For engineers reviewing the TPSMP6.8AHM3_A/I datasheet, TPSMP6.8AHM3_A/I pinout, TPSMP6.8AHM3_A/I application, or TPSMP6.8AHM3_A/I equivalent, key selection criteria include clamping voltage (10.5 V at 23.8 A), low incremental surge resistance, AEC-Q101 qualification, MSL Level 1 rating, and unidirectional polarity with cathode band marking.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve fast response time (<1 ns), low clamping ratio (VC/VBR ≈ 1.64), and stable performance up to TJ = 185 °C. Its junction passivation enables robust operation under repeated surge stress and high-temperature automotive environments.
The device operates exclusively in unidirectional mode with a defined cathode terminal, requires no biasing circuitry, and delivers consistent clamping behavior across its specified 10/1000 µs surge waveform envelope - validated per ANSI/IEEE C62.35 and JESD22-B102 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V at 10 mA - defines precise overvoltage triggering threshold for reliable system-level ESD/surge immunity |
| VWM | 5.8 V - maximum continuous reverse voltage before leakage exceeds 300 µA, ensuring compatibility with 5 V logic and CAN bus interfaces |
| VC @ IPPM | 10.5 V at 23.8 A - clamping voltage during 10/1000 µs surge, limiting protected IC voltage stress to safe levels |
| PPPM | 250 W - peak pulse power handling capability on standard PCB pads (5 mm × 5 mm), enabling compact board-level protection |
| TJ max | +185 °C - supports under-hood automotive applications without thermal derating penalties |
| Package | SMP (DO-220AA) - ultra-low profile (1.0 mm height), halogen-free, RoHS-compliant, and AEC-Q101 qualified |
| Polarity | Unidirectional with cathode band - simplifies layout verification and prevents reverse-bias misconnection |
Pinout & Package
Package: SMP (DO-220AA), surface-mount, two-terminal device with cathode marked by color band. Dimensions: 3.61 mm × 1.88 mm × 1.0 mm (L × W × H). Matte tin-plated leads, solderable per J-STD-002 and JESD22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to protected line's lower-potential side (e.g., ground return path); must be routed with low-inductance trace |
| Cathode | Current exit point during reverse-biased clamping | Marked by color band; connects to protected signal/power line - determines clamping polarity and directionality |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per JESD22 standards |
| MSL Level 1 (260 °C peak) | Enables single-pass reflow assembly without moisture sensitivity concerns or baking requirements |
| Low profile (1.0 mm height) | Reduces board stack height and improves airflow in dense automotive modules and ADAS sensor housings |
| 185 °C junction rating | Eliminates thermal derating in engine control units operating near 150 °C ambient |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving protection margin for sensitive microcontrollers and transceivers |

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 clamping voltage (11.5 V vs. 10.5 V), lower PPPM (400 W but rated at 13 V VBR family; TPSMP6.8A has 250 W at 6.8 V), SMA package (larger footprint, 2.2 mm height) | Less suitable for space-constrained automotive modules; higher clamping may exceed IC absolute max ratings | Select TPSMP6.8AHM3_A/I when board height <1.1 mm and clamping voltage ≤10.5 V is required |
| TPSMA6.8A | Same VBR range but SMA package (DO-214AC), 2.79 mm height, 400 W PPPM only at ≥13 V VBR; TPSMP6.8AHM3_A/I offers 250 W at 6.8 V with 1.0 mm profile | Not AEC-Q101 qualified; lacks MSL Level 1 and 185 °C TJ rating | Choose TPSMP6.8AHM3_A/I for automotive-grade designs requiring full AEC-Q101 compliance and ultra-low profile |
Compared with SMAJ6.8A and TPSMA6.8A, TPSMP6.8AHM3_A/I provides superior height-constrained performance, tighter clamping, and full automotive qualification - making it the preferred choice for next-generation ECU, ADAS, and body electronics where thermal, mechanical, and reliability margins are critical.

FAQ
What is the clamping voltage of the TPSMP6.8AHM3_A/I at its rated peak pulse current?
The TPSMP6.8AHM3_A/I has a maximum clamping voltage (VC) of 10.5 V at its peak pulse current (IPPM) of 23.8 A, measured under the standardized 10/1000 µs waveform. This value ensures protected downstream ICs remain below their absolute maximum voltage ratings during surge events. The TPSMP6.8AHM3_A/I achieves this with low incremental surge resistance and optimized junction passivation.
Is the TPSMP6.8AHM3_A/I qualified for automotive applications?
Yes, the TPSMP6.8AHM3_A/I is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature. It meets JESD22-B102 whisker testing, MSL Level 1 (260 °C peak reflow), and is halogen-free and RoHS-compliant. These qualifications make the TPSMP6.8AHM3_A/I suitable for under-hood and body electronics applications where reliability under thermal and mechanical stress is mandatory.
What does the "HM3_A/I" suffix indicate in TPSMP6.8AHM3_A/I?
The "HM3" denotes the halogen-free, RoHS-compliant, AEC-Q101-qualified SMP package variant; "A" is the revision code; "I" specifies the packaging format - 13-inch diameter plastic tape and reel with 10,000 units per reel. This differs from "H" (7-inch reel, 3,000 units) and confirms full compliance traceability for automotive production use.
How does the TPSMP6.8AHM3_A/I compare to standard SMA-package TVS diodes in terms of board space?
The TPSMP6.8AHM3_A/I uses the SMP (DO-220AA) package measuring 3.61 mm × 1.88 mm × 1.0 mm, offering ~45 % smaller footprint and 55 % lower height than SMA (DO-214AC) packages. This allows denser routing in automotive modules and eliminates height conflicts with nearby connectors or shields - a key advantage not achievable with SMAJ6.8A or TPSMA6.8A.
What is the maximum reverse leakage current of the TPSMP6.8AHM3_A/I at its stand-off voltage?
At VWM = 5.8 V and TA = 25 °C, the TPSMP6.8AHM3_A/I exhibits a maximum reverse leakage current (IR) of 300 µA. At elevated temperature (TJ = 150 °C), leakage increases to 1000 µA - still within acceptable limits for most 5 V logic and sensor interface applications. This low leakage preserves signal integrity and minimizes standby power loss.
