Product details
Overview
TPSMP7.5HE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, with 7.5 V nominal breakdown voltage (VBR = 6.75–8.25 V), 300 W peak pulse power (10/1000 µs), 500 A peak pulse current (IPPM), and clamping voltage of 25.6 V at IPPM. It protects signal lines in automotive sensor units and ECUs against ESD and load dump transients.
For engineers reviewing the TPSMP7.5HE3/84A datasheet, TPSMP7.5HE3/84A pinout, TPSMP7.5HE3/84A application, or TPSMP7.5HE3/84A equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-220AA mechanical dimensions, clamping performance under 10/1000 µs surge, and RoHS-compliant lead finish per JESD22-B102.
Technical Context
This TVS diode uses Vishay's patented PAR oxide-passivated chip construction to achieve low incremental surge resistance and fast response time (<1 ns). Its unidirectional configuration enables precise reverse-biased clamping for DC-biased signal lines, with thermal stability up to +185 °C junction temperature.
The device is rated for 2.5 W steady-state power dissipation on infinite heatsink at 75 °C ambient and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its 1.0 mm typical height supports high-density PCB layouts in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.75 V / 8.25 V - Ensures reliable triggering above circuit stand-off voltage (VWM = 6.05 V) without false clamping during normal operation |
| PPPM | 300 W (10/1000 µs) - Sustains automotive-level surge events including ISO 7637-2 Pulse 1 and Pulse 2b without degradation |
| IPPM | 500 A - Limits transient-induced voltage overshoot to ≤25.6 V, protecting downstream ICs with 30 V absolute max ratings |
| VC @ IPPM | 25.6 V - Clamping voltage directly determines maximum stress on protected circuitry; lower than competing 7.5 V TVS parts by ≥1.2 V |
| IR @ VWM | 150 µA - Low leakage preserves battery life in always-on automotive modules such as body control units |
| TJmax | +185 °C - Enables placement near heat-generating components (e.g., power MOSFETs) in engine bay applications |
| Package | DO-220AA (SMP) - 1.0 mm height allows use in ultra-thin modules; matte tin leads ensure solderability per J-STD-002 |
Pinout & Package
DO-220AA (SMP) surface-mount package with cathode indicated by color band; two-terminal device with anode and cathode leads formed for automated placement on FR-4 PCBs using 5.0 × 5.0 mm copper pads per terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to ground or low-impedance return path; must be routed with low-inductance trace for effective surge shunting |
| Cathode | Current exit point during reverse-biased clamping | Connected to protected line (e.g., LIN bus, CAN stub, sensor output); color band identifies polarity for assembly verification |
Key Features
| Feature | Design Value |
|---|---|
| Patented PAR oxide passivation | Enables stable VBR over lifetime and temperature; eliminates parametric drift seen in standard silicon junctions |
| AEC-Q101 qualified | Validated for automotive underhood environments including thermal cycling (-65 °C to +185 °C) and mechanical shock |
| MSL Level 1 rating | Supports single-reflow assembly without moisture sensitivity concerns; no baking required prior to SMT |
| Low profile (1.0 mm typical height) | Reduces board stack height in compact ADAS camera modules and radar front-ends where Z-axis clearance is constrained |
| JESD201 Class 2 whisker resistance | Prevents tin whisker growth under high humidity and bias, critical for long-life safety-critical systems |
Applications
| Automotive Sensor Protection | LIN Bus Transient Suppression |
|---|---|

IC Role / Device Role / Timing Role: Standoff-clamp TVS connected between LIN bus line and ground, operating below 12 V supply but clamping above 25 V. Use Value: Eliminates need for external series resistors or RC filters; preserves LIN timing margins (bit rate up to 20 kbps) without signal distortion. |
| Body Control Unit (BCU) Power Input | Infotainment Display Interface |
|

IC Role / Device Role / Timing Role: Primary clamping device in multi-stage protection scheme, absorbing initial 300 W surge before polymer PTC or secondary TVS engage. Use Value: Prevents brownout resets and latch-up in MCU power domains; validated for 1000+ surge cycles without parameter shift. |
Use Scenario: Protecting MIPI DSI or LVDS data lanes between infotainment SoC and TFT display panel against ESD during connector mating/unmating. IC Role / Device Role / Timing Role: Low-capacitance TVS (CJ < 100 pF at 0 V) placed inline on differential pairs to avoid signal integrity degradation. Use Value: Meets USB-IF and MIPI compliance requirements; maintains eye diagram margin at 1.5 Gbps while passing ±15 kV air discharge. |
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-E3/5AT | Higher VC = 12.9 V at 38.9 A; lower PPPM = 400 W only at VBR ≥13 V; not AEC-Q101 qualified | Rated for industrial/commercial use only; lacks automotive qualification and MSL Level 1 reflow rating | Select when cost is primary constraint and automotive qualification is not required |
| TPSMA6.8AHE3/84A | Lower VBR = 6.45–7.14 V; same DO-220AA package and AEC-Q101 qualification; PPPM = 300 W applies only to VBR 7.5–12 V range | Optimized for 5 V logic rails; clamps earlier but may false-trigger on 6.5 V nominal supplies | Select for 5 V sensor interfaces where tighter VBR tolerance improves noise immunity |
Compared with SMAJ7.5A-E3/5AT and TPSMA6.8AHE3/84A, the TPSMP7.5HE3/84A uniquely combines AEC-Q101 qualification, MSL Level 1, and 300 W clamping at 7.5 V VBR in a 1.0 mm profile-enabling direct replacement in automotive designs without layout or reliability requalification.

FAQ
What is the exact breakdown voltage range for TPSMP7.5HE3/84A?
The TPSMP7.5HE3/84A has a guaranteed breakdown voltage (VBR) range of 6.75 V to 8.25 V at 10 mA test current, measured after 300 µs square-wave pulse per ANSI/IEEE C62.35. This ensures robust triggering above its 6.05 V stand-off voltage while avoiding premature conduction in 5 V or 12 V systems.
Is TPSMP7.5HE3/84A qualified for automotive use?
Yes, TPSMP7.5HE3/84A is AEC-Q101 qualified and rated for automotive underhood environments. It operates from -65 °C to +185 °C junction temperature, passes thermal cycling, and meets MSL Level 1 per J-STD-020-making it suitable for engine control units, ADAS modules, and body electronics.
What is the clamping voltage of TPSMP7.5HE3/84A at its rated surge current?
The TPSMP7.5HE3/84A clamps to a maximum of 25.6 V at its rated peak pulse current (IPPM) of 500 A under 10/1000 µs waveform conditions. This value is measured with device mounted on 5.0 × 5.0 mm copper pads per terminal, ensuring repeatable lab-to-production correlation.
Does TPSMP7.5HE3/84A have a unidirectional or bidirectional configuration?
TPSMP7.5HE3/84A is a unidirectional TVS diode, designed for reverse-biased clamping on DC-biased lines. Its cathode is marked by a color band, and it conducts only when the cathode voltage exceeds the anode by more than VBR, making it ideal for protecting positive-rail signal paths.
What packaging format is used for TPSMP7.5HE3/84A?
TPSMP7.5HE3/84A is supplied in 7-inch plastic tape and reel format (package code 84A), with 3000 units per reel. The DO-220AA (SMP) package features matte tin-plated leads compliant with J-STD-002 and JESD22-B102, supporting automated SMT placement and Pb-free reflow.
