Product details
Overview
TPSMP10AHE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, with 9.5 V to 10.5 V breakdown voltage (VBR), 14.5 V clamping voltage (VC) at 20.7 A peak pulse current, and 300 W peak pulse power rating for 10/1000 µs waveform - designed for robust ESD and surge protection of automotive sensor signal lines and microcontroller I/O pins.
For engineers reviewing the TPSMP10AHE3/84A datasheet, TPSMP10AHE3/84A pinout, TPSMP10AHE3/84A application, or TPSMP10AHE3/84A equivalent, key selection criteria include AEC-Q101 qualification, low-profile 1.0 mm height, MSL Level 1 moisture sensitivity, and verified clamping performance under 10/1000 µs transients per ANSI/IEEE C62.35.
Technical Context
The TPSMP10AHE3/84A employs Vishay's patented PAR oxide-passivated chip construction to achieve low incremental surge resistance and excellent clamping capability. Its unidirectional configuration provides precise reverse-biased overvoltage protection with fast response time and stable thermal performance up to +185 °C junction temperature.
Designed for surface-mount automated placement on FR-4 PCBs with 5.0 × 5.0 mm copper pads per terminal, it meets J-STD-020 MSL Level 1 (260 °C reflow peak) and JESD201 Class 2 whisker resistance. The device operates within -65 °C to +185 °C junction range and delivers 2.5 W steady-state power dissipation at 75 °C ambient on infinite heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.50 V / 10.5 V - ensures reliable triggering above 8.55 V stand-off voltage while avoiding false trips during normal 12 V automotive rail fluctuations |
| VC @ IPPM | 14.5 V at 20.7 A - limits downstream IC voltage stress during 300 W transient events, protecting 15 V-rated logic interfaces |
| PPPM | 300 W (10/1000 µs) - sustains high-energy surges common in automotive load-dump and ISO 7637-2 Pulse 5a scenarios |
| IR @ VWM | 5.0 µA max at 8.55 V - guarantees negligible leakage current in battery-sensitive always-on circuits |
| TJ max | +185 °C - supports under-hood deployment near engines and power electronics without derating penalties |
| Package | DO-220AA (SMP) - 1.0 mm typical height enables ultra-thin module designs and compatibility with standard SMT pick-and-place equipment |
| AEC-Q101 | Qualified - validated for automotive reliability including temperature cycling, HTRB, and ESD per AEC specification |
Pinout & Package
DO-220AA (SMP) package: cathode-indicating color band on one end; two-terminal axial-lead configuration optimized for high-current transient conduction. Matte tin-plated leads meet J-STD-002 solderability and JESD22-B102 mechanical integrity standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection to protected circuit ground | Completes surge current path during reverse-biased transient events; requires low-inductance grounding to minimize VC overshoot |
| Cathode (banded end) | High-side connection to protected signal or power line | Receives transient energy; polarity marking prevents misorientation during automated assembly |
Key Features
| Feature | Design Value |
|---|---|
| Patented PAR oxide passivation | Enables stable VBR tolerance and low dynamic impedance across 1000+ surge cycles without parameter drift |
| MSL Level 1 rating | Allows single-reflow assembly without baking, reducing manufacturing cost and handling risk for automotive Tier 1 suppliers |
| 1.0 mm profile | Permits integration into space-constrained ADAS camera modules and compact body control units without height interference |
| RoHS/WEEE compliant | Meets EU regulatory requirements for automotive electronics with no lead, cadmium, mercury, or hexavalent chromium |
| Low incremental surge resistance | Minimizes VC rise during fast-rising transients (<1 ns), improving protection margin for high-speed CAN FD and LIN bus nodes |
Applications
| Automotive Sensor Protection | Microcontroller I/O Clamping |
|---|---|
Use Scenario: Protecting analog output lines of engine coolant temperature (ECT) and manifold absolute pressure (MAP) sensors exposed to ISO 7637-2 Pulse 1 and Pulse 2b transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor signal trace and chassis ground, clamping transients before they reach the ADC input of the MCU. Use Value: Maintains signal integrity below 14.5 V during 300 W surges, preventing ADC saturation and erroneous fault codes in OBD-II systems. | Use Scenario: Safeguarding GPIO pins of automotive-grade MCUs (e.g., NXP S32K series) connected to external switches, LEDs, or diagnostic connectors. IC Role / Device Role / Timing Role: Standoff protection element with 8.55 V working voltage, activated only during ESD or load dump events exceeding VBR. Use Value: Limits pin voltage to ≤14.5 V during 20.7 A transients, preserving I/O cell oxide integrity and enabling >10 kV HBM ESD immunity. |
| Infotainment Display Interface | Body Control Module Power Rail |
Use Scenario: Shielding LVDS or FPD-Link III data lanes between head unit and TFT display from coupling-induced transients in vehicle cabin harnesses. IC Role / Device Role / Timing Role: Low-capacitance (typ. <100 pF) unidirectional clamp on each differential pair, referenced to local ground plane. Use Value: Prevents bit errors and display flicker by clamping sub-100 ns spikes without degrading 1 Gbps signal integrity. | Use Scenario: Secondary surge suppression on 12 V supply inputs to BCM modules, downstream of primary fuse and main TVS array. IC Role / Device Role / Timing Role: Fast-response secondary clamp absorbing residual energy after primary protection, rated for repetitive 300 W pulses. Use Value: Extends system-level surge survivability beyond ISO 16750-2 requirements by limiting rail sag and preventing brownout resets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/5AT | DO-214AC (SMA) package; 10.0 V VBR min, 16.0 V VC at 19.3 A; 400 W PPPM; higher 2.3 mm profile | Less suitable for ultra-low-height modules; wider thermal footprint required for same power dissipation | Select when board space allows larger footprint and higher clamping voltage is acceptable for 15 V tolerant circuits |
| TPSMAJ10A | Same DO-214AC package as SMAJ10A-E3/5AT but Vishay-branded; identical electrical specs and AEC-Q101 qualification | No functional difference; differs only in packaging code and reel configuration (e.g., 7" vs 13" tape) | Preferred for direct Vishay supply chain continuity and identical qualification documentation |
Compared with SMAJ10A-E3/5AT and TPSMAJ10A, the TPSMP10AHE3/84A offers 1.0 mm height and DO-220AA footprint - critical for next-gen automotive ECUs where Z-axis space is constrained - while maintaining AEC-Q101 compliance and matching VBR/VC performance at lower mounting volume.

FAQ
What is the exact breakdown voltage range specified for TPSMP10AHE3/84A?
The TPSMP10AHE3/84A has a guaranteed breakdown voltage (VBR) range of 9.50 V minimum to 10.5 V maximum, measured at 1 mA test current per ANSI/IEEE C62.35. This tight 1.0 V window ensures predictable turn-on behavior in 12 V automotive systems and avoids nuisance triggering during normal rail ripple.
Is TPSMP10AHE3/84A qualified for automotive use per AEC-Q101?
Yes, TPSMP10AHE3/84A is explicitly AEC-Q101 qualified, as confirmed in Vishay document 88471 revision 21-Oct-08. It undergoes full stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev G, making it suitable for under-hood and safety-critical automotive applications.
What is the clamping voltage of TPSMP10AHE3/84A at its rated peak pulse current?
The TPSMP10AHE3/84A clamps to a maximum of 14.5 V at its rated peak pulse current of 20.7 A (10/1000 µs waveform). This value is measured per standard test conditions and defines the maximum voltage imposed on protected circuitry during worst-case transient events.
Does TPSMP10AHE3/84A have moisture sensitivity level (MSL) rating?
Yes, TPSMP10AHE3/84A is rated MSL Level 1 per J-STD-020, with a maximum reflow peak temperature of 260 °C. This allows unlimited floor life and single-reflow soldering without preconditioning bake, simplifying SMT assembly for automotive production lines.
What package type and dimensions does TPSMP10AHE3/84A use?
TPSMP10AHE3/84A uses the DO-220AA (SMP) package, measuring 2.67 mm × 1.88 mm × 1.0 mm (L × W × H) with a cathode band marking. Its 1.0 mm typical height enables integration into ultra-thin automotive modules where Z-axis space is tightly constrained.
