Product details
Overview
TPSMP10HE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, with 9.0–11.0 V breakdown voltage (VBR), 20.0 A peak pulse current (IPPM), 15.0 V clamping voltage (VC) at IPPM, and AEC-Q101 qualification for under-hood electronics protection.
For engineers reviewing the TPSMP10HE3/84A datasheet, TPSMP10HE3/84A pinout, TPSMP10HE3/84A application, or TPSMP10HE3/84A equivalent, key selection criteria include unidirectional clamping performance, 1.0 mm profile for space-constrained PCBs, 2.5 W steady-state power dissipation, and compatibility with automated SMT placement per J-STD-002.
Technical Context
This TVS diode uses patented PAR oxide-passivated chip construction to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and load-dump transients in automotive signal lines. Its unidirectional configuration provides forward conduction path while clamping reverse surges above VBR.
The device operates across -65 °C to +185 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. It delivers 200 W peak pulse power (10/1000 µs waveform) at 25 °C on 5.0 × 5.0 mm copper pads - validated per Fig. 1 and Fig. 3 in Document 88471.
Key Specifications

|---|---|
| VBR (min/max) | 9.0 V / 11.0 V - ensures reliable triggering above system nominal voltage (e.g., 9 V automotive rail) without false clamping |
| VC @ IPPM | 15.0 V - limits downstream IC voltage stress during 20.0 A transient events |
| IPPM | 20.0 A - supports robust protection against ISO 7637-2 Pulse 1/2a/5a waveforms in 12 V systems |
| PPPM | 200 W - rated for 10/1000 µs surge per Fig. 1, derated linearly above 25 °C ambient |
| TJ max. | +185 °C - enables operation in high-temperature engine bay environments |

|---|---|
|
Use Scenario: Protecting analog sensor outputs (e.g., MAP, O2, crankshaft position sensors) from coupled transients on 5 V or 12 V supply rails. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor VCC and GND to clamp positive-going spikes before they reach precision ADC inputs. Use Value: Maintains <5 µA leakage at 8.1 V stand-off to avoid sensor bias error; clamps to 15.0 V within nanoseconds to preserve signal integrity. |
Use Scenario: Safeguarding microcontroller power domains in ECUs exposed to battery load-dump events (ISO 7637-2 Pulse 5a). IC Role / Device Role / Timing Role: Primary front-end TVS on main 12 V input, positioned upstream of DC/DC converter and LDO regulators. Use Value: Absorbs 200 W transient energy at 20.0 A without failure, preventing brownout or latch-up in 185 °C-rated SoCs. |
| Infotainment System USB Data Line Protection | Body Control Module (BCM) LIN Bus Protection |
|
Use Scenario: Shielding USB 2.0 D+/D− lines in head units from ESD (IEC 61000-4-2 ±15 kV contact) and cable-induced surges. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed directly at USB connector, referenced to local ground plane. Use Value: Delivers <15 pF junction capacitance (per Fig. 4) to avoid signal integrity degradation at 480 Mbps; clamps ESD to <15 V. |
Use Scenario: Securing LIN bus transceivers in door modules and lighting controllers against battery reversal and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS connected between LIN line and chassis ground, leveraging its 1.0 mm height for compact connector-side layout. Use Value: Withstands 40 A non-repetitive forward surge (IFSM) during polarity reversal, ensuring no latch-up or permanent damage to LIN PHY. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | DO-214AC (SMA) package; 1.8 mm height; 200 W PPPM; VC = 16.0 V @ 17.1 A | Higher profile limits use in ultra-thin modules; lower IPPM reduces margin for ISO 7637-2 Pulse 5a | Choose SMAJ10A only if DO-220AA footprint is unavailable and 0.8 mm extra height is acceptable |
| TPSMA6.8A | Same DO-220AA package; lower VBR (6.45–7.14 V); VC = 10.5 V @ 500 A; PPPM = 300 W | Better suited for 5 V logic rails; not rated for 12 V automotive supply clamping due to lower VBR | Use TPSMA6.8A for 5 V MCU I/O protection; TPSMP10HE3/84A remains optimal for 12 V supply-line clamping |
Compared with SMAJ10A, TPSMP10HE3/84A offers 0.8 mm lower profile and tighter VBR tolerance (±11 % vs ±15 %), improving design margin in space-constrained automotive modules; versus TPSMA6.8A, it provides higher VBR essential for 12 V system immunity without premature conduction.

FAQ
What is the breakdown voltage range for TPSMP10HE3/84A?
The TPSMP10HE3/84A has a guaranteed breakdown voltage (VBR) range of 9.0 V to 11.0 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This range ensures reliable turn-on above typical 9 V automotive nominal rails while avoiding false triggering during normal operation. The exact VBR for each unit falls within this window and is verified during production screening.
Is TPSMP10HE3/84A suitable for bidirectional transient suppression?
No, TPSMP10HE3/84A is a unidirectional TVS diode and must be used with correct polarity - cathode connected to the higher-potential line (e.g., 12 V supply), anode to ground. It does not suppress negative-going transients below ground. For bidirectional protection, a separate device such as TPSMP10AHE3/84A (which has symmetrical VBR) or a dedicated bidirectional TVS is required.
What is the maximum clamping voltage of TPSMP10HE3/84A during a surge event?
The TPSMP10HE3/84A clamps to a maximum of 15.0 V when subjected to its rated 20.0 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per Fig. 1 and Fig. 3 in Vishay Document 88471 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Does TPSMP10HE3/84A meet automotive reliability standards?
Yes, TPSMP10HE3/84A is AEC-Q101 qualified and manufactured as a high-reliability automotive-grade part (HE3 suffix). It passes stress tests including high-temperature operating life (HTOL), temperature cycling (TCT), and human-body-model ESD (HBM ≥ 8 kV), making it suitable for deployment in engine control units, sensor modules, and other mission-critical automotive electronics.
What is the recommended PCB pad layout for TPSMP10HE3/84A to achieve full power rating?
To achieve the full 200 W peak pulse power rating, TPSMP10HE3/84A must be mounted on FR-4 PCB with 5.0 × 5.0 mm copper pads attached to each terminal, as specified in Note (2) of Document 88471. Smaller pads reduce thermal dissipation and surge current capability, potentially causing premature failure during ISO 7637-2 Pulse 5a events.
