Product details
Overview
TPSMP7.5AHE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, with 7.13 V to 7.88 V breakdown voltage (VBR), 6.40 V stand-off voltage (VWM), 26.5 V clamping voltage (VC) at 500 A peak pulse current, and 300 W peak pulse power rating for 10/1000 µs waveform - designed for robust overvoltage protection of automotive sensor signal lines.
For engineers reviewing the TPSMP7.5AHE3/84A datasheet, TPSMP7.5AHE3/84A pinout, TPSMP7.5AHE3/84A application, or TPSMP7.5AHE3/84A equivalent, key selection criteria include AEC-Q101 qualification, low-profile 1.0 mm height, MSL Level 1 moisture sensitivity, and verified clamping performance under 500 A surge conditions per IEC 61000-4-5.
Technical Context
This TVS diode operates as a unidirectional clamping device, activated above its specified VBR range (7.13–7.88 V) and limiting transient voltages to ≤26.5 V at 500 A. Its patented PAR oxide-passivated chip construction ensures stable breakdown characteristics and low incremental surge resistance.
Designed for surface-mount placement on FR-4 PCBs with 5.0 × 5.0 mm copper pads per terminal, it supports automated assembly and meets J-STD-020 reflow profile (260 °C peak). It is rated for junction temperatures from –65 °C to +185 °C and qualified to AEC-Q101 for automotive reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V - defines precise voltage threshold at which clamping initiates under 10 mA test current |
| VWM | 6.40 V - maximum continuous reverse operating voltage before leakage exceeds 150 µA |
| VC @ IPPM | 26.5 V @ 500 A - clamped voltage during 10/1000 µs surge, ensuring downstream ICs see <27 V stress |
| PPPM | 300 W - peak pulse power handling for 10/1000 µs transients, enabling protection against ISO 7637-2 Pulse 1/2a/5a |
| IFSM | 40 A - withstands 10 ms half-sine surge without failure, supporting load-dump immunity in 12 V systems |
| TJ max. | +185 °C - enables operation in under-hood environments with high ambient thermal stress |
| Package | DO-220AA (SMP) - ultra-low-profile 1.0 mm height, 3.61 mm × 2.18 mm footprint, optimized for space-constrained automotive modules |
Pinout & Package
DO-220AA (SMP) package: two-terminal surface-mount device with cathode indicated by color band; terminals are matte tin-plated for solderability per J-STD-002 and JESD22-B102, and qualified to JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to protected line (e.g., sensor output); conducts during positive surges when cathode is biased higher |
| Cathode | Clamping reference / ground reference | Connected to system ground or low-impedance return; defines polarity and sets VBR threshold relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| Patented PAR oxide-passivated chip | Ensures repeatable VBR tolerance (±5.5%) and long-term stability under thermal cycling and humidity |
| AEC-Q101 qualification | Validated for automotive use including HTOL, temperature cycling, and ESD testing per stress requirements |
| MSL Level 1 (260 °C peak) | Enables single-reflow assembly without pre-baking, reducing manufacturing complexity and cost |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 16750-2 load dump edges) |
| RoHS-compliant & UL 94 V-0 molding | Meets global environmental compliance and flammability safety standards for automotive electronics |
Applications
| Automotive Sensor Signal Protection | Body Control Module (BCM) Input Lines |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | DO-214AC (SMA) package; 7.22–8.02 V VBR; 26.5 V VC @ 43.5 A; 400 W PPPM | Lower surge current rating (43.5 A vs. 500 A); larger 4.5 mm × 2.7 mm footprint | Select SMAJ7.5A only if board space allows larger package and surge requirements are ≤43.5 A. |
| TPSMA6.8A | Same DO-220AA package; lower 6.45–7.14 V VBR; 23.8 V VC @ 1000 A; 300 W PPPM | Lower clamping voltage but reduced stand-off (5.80 V); not suitable for 6.4 V nominal systems | Choose TPSMA6.8A only where system VWM is ≤5.8 V and tighter clamping is prioritized over margin. |
Compared with SMAJ7.5A and TPSMA6.8A, the TPSMP7.5AHE3/84A uniquely combines AEC-Q101 qualification, 500 A surge capability in the ultra-compact DO-220AA outline, and 6.40 V stand-off - making it optimal for next-generation automotive sensor nodes requiring high reliability in minimal PCB area.

FAQ
What is the exact breakdown voltage range for TPSMP7.5AHE3/84A?
The TPSMP7.5AHE3/84A has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, measured per ANSI/IEEE C62.35. This tight ±5.5% tolerance ensures consistent clamping behavior across production lots and temperature extremes from –65 °C to +185 °C.
Is TPSMP7.5AHE3/84A qualified for automotive use?
Yes, TPSMP7.5AHE3/84A is AEC-Q101 qualified and designated as high-reliability/automotive grade (suffix "A"). It undergoes rigorous stress testing including high-temperature operating life, temperature cycling, and ESD per JESD22-A114, confirming suitability for under-hood and chassis-mounted automotive electronics.
What does the "HE3/84A" suffix indicate in TPSMP7.5AHE3/84A?
The "HE3" denotes RoHS-compliant, high-reliability construction with JESD201 Class 2 whisker-resistant matte tin plating. The "/84A" specifies packaging: 7-inch plastic tape-and-reel with 3000 units per reel, using Vishay's standard DO-220AA carrier tape configuration.
How does TPSMP7.5AHE3/84A perform under ISO 7637-2 Pulse 5a (load dump)?
TPSMP7.5AHE3/84A handles ISO 7637-2 Pulse 5a transients via its 300 W peak pulse power rating (10/1000 µs) and 40 A IFSM rating. When used with appropriate PCB layout (5.0 × 5.0 mm copper pads), it clamps 500 A surges to ≤26.5 V - well within safe limits for 3.3 V/5 V interface ICs downstream.
Can TPSMP7.5AHE3/84A be used in bidirectional configurations?
No, TPSMP7.5AHE3/84A is unidirectional only, as confirmed in its datasheet features. For bidirectional protection, Vishay offers complementary parts such as the TPSMP7.5CAHE3/84A - a center-tapped variant - or discrete back-to-back configurations; the TPSMP7.5AHE3/84A must be oriented with cathode toward protected circuit ground.
