Product details
Overview
TPSMA8.2HE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features 8.2 V breakdown voltage (VBR), 7.02 V stand-off voltage (VWM), 33.1 V clamping voltage at 200 A peak pulse current, 400 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - used in automotive sensor line protection and industrial power supply input stages.
For engineers reviewing the TPSMA8.2HE3_A/I datasheet, TPSMA8.2HE3_A/I pinout, TPSMA8.2HE3_A/I application, or TPSMA8.2HE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, TJ = 185 °C capability, low clamping ratio (VC/VBR ≈ 4.04), and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under repetitive surge conditions. Its 10/1000 µs waveform rating of 400 W and 200 A peak pulse current (IPPM) is validated with 0.2" × 0.2" copper pads per JEDEC standards.
The device exhibits a positive temperature coefficient of VBR (+0.056 %/°C), enabling predictable voltage drift over temperature. It meets MSL Level 1 (260 °C peak reflow) and is qualified to AEC-Q101 for automotive use - confirmed by HE3 suffix designation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 7.79 / 8.20 / 8.61 V - ensures reliable turn-on above system operating voltage while avoiding false triggering |
| VWM | 7.02 V - maximum continuous reverse voltage before leakage exceeds 50 µA at 25 °C |
| VC @ IPPM | 33.1 V - clamps 200 A transient to safe level for downstream 3.3 V or 5 V ICs |
| PPPM | 400 W - handles standard lightning/surge immunity tests (IEC 61000-4-5, Level 3) |
| TJ max | +185 °C - supports under-hood automotive environments without derating |
| Polarity | Unidirectional - protects against positive-going transients only; requires external circuit design for bidirectional needs |
| Package | SMA (DO-214AC) - industry-standard SMD outline with cathode band marking and 0.074" pad pitch |
Pinout & Package
SMA (DO-214AC) surface-mount package with molded epoxy body, matte tin-plated leads, and cathode band marking. Dimensions: 4.93 mm × 3.99 mm × 2.29 mm (L × W × H); weight: 0.064 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry during forward conduction or transient clamping | Connected to protected line (e.g., 12 V rail or sensor output); must be routed with low-inductance path to ground |
| Cathode | Current exit during clamping; marked with color band | Connected to system ground or low-impedance return; defines unidirectional clamping direction |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | VBR = 8.89–9.82 V (min/typ/max); VC = 13.6 V @ 31.2 A; lower PPPM = 400 W but lower IPPM = 31.2 A | Lower clamping energy handling; suitable only for low-current signal lines, not power rails | Select when protecting 3.3 V logic with tighter VWM margin needed; not recommended for 12 V automotive loads |
| 1.5SMC8.2A | Same VBR/VWM specs but in larger SMC (DO-214AB) package; higher thermal mass; PD = 1.5 W vs. 1.0 W | Better sustained power dissipation; requires larger PCB footprint and different pad layout | Choose for high-temperature ambient designs (>105 °C) where thermal relief is critical; not drop-in compatible due to package size |
Compared with SMAJ8.0A and 1.5SMC8.2A, the TPSMA8.2HE3_A/I offers AEC-Q101 qualification, MSL Level 1 reflow compatibility, and optimized SMA footprint for space-constrained automotive modules - making it preferred for production-grade vehicle electronics where qualification and manufacturability are mandatory.

FAQ
What is the exact breakdown voltage range for TPSMA8.2HE3_A/I?
The TPSMA8.2HE3_A/I has a guaranteed breakdown voltage (VBR) range of 7.79 V (minimum) to 8.61 V (maximum) at 10 mA test current, with a typical value of 8.20 V. This specification is measured per ANSI/IEEE C62.35 and confirmed in the official Vishay datasheet (Document Number: 88405, Revision: 23-Jan-2024). The TPSMA8.2HE3_A/I maintains this tolerance across its qualified operating temperature range.
Is TPSMA8.2HE3_A/I AEC-Q101 qualified?
Yes, the TPSMA8.2HE3_A/I is AEC-Q101 qualified. The "HE3" suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified construction, as stated in the Vishay datasheet under Mechanical Data and Ordering Information sections. This qualification covers stress tests including HTGB, HTRB, AC-H3TRB, and temperature cycling - validating suitability for automotive under-hood and cabin applications.
What does the "_A/I" suffix mean in TPSMA8.2HE3_A/I?
The "_A/I" suffix in TPSMA8.2HE3_A/I indicates revision code "A" and packaging in 13-inch diameter plastic tape and reel with 7500 units per reel. Per Vishay's ordering information table, "I" denotes the 13″ reel format, while "A" is the assembly revision level - both defined in the official datasheet (page 3, Ordering Information section). This format ensures automated SMT placement compatibility and traceability.
Can TPSMA8.2HE3_A/I be used in bidirectional protection circuits?
No, the TPSMA8.2HE3_A/I is unidirectional only, as confirmed in the Features section of the datasheet. It clamps positive transients relative to ground and conducts in forward bias during negative excursions - potentially damaging sensitive inputs. For bidirectional protection, a pair of TPSMA8.2HE3_A/I devices in series-opposed configuration or a dedicated bidirectional TVS (e.g., TPSMA8.2CA) must be used instead.
What is the maximum clamping voltage of TPSMA8.2HE3_A/I at rated surge current?
The maximum clamping voltage (VC) of TPSMA8.2HE3_A/I is 33.1 V at 200 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is specified in the Electrical Characteristics table (page 2 of datasheet 88405) and reflects worst-case clamping performance at TA = 25 °C with proper PCB mounting (0.2" × 0.2" copper pads). The TPSMA8.2HE3_A/I maintains this clamping level across its full operational temperature range.
