Product details
Overview
TPSMP11HE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, with 9.9 V to 12.1 V breakdown voltage (VBR), 18.5 A peak pulse current (IPPM), and 16.2 V clamping voltage (VC) at IPPM, designed for robust ESD and surge protection of sensor signal lines in automotive ECUs.
For engineers reviewing the TPSMP11HE3/84A datasheet, TPSMP11HE3/84A pinout, TPSMP11HE3/84A application, or TPSMP11HE3/84A equivalent, key selection criteria include AEC-Q101 qualification, 1.0 mm profile for space-constrained PCB layouts, low incremental surge resistance, and RoHS-compliant matte tin terminations meeting J-STD-002 solderability standards.
Technical Context
This TVS diode employs Vishay's patented PAR oxide-passivated chip construction, enabling excellent clamping performance and fast response time (<1 ns) under 10/1000 µs surge transients. Its unidirectional configuration provides precise reverse-biased overvoltage protection without forward conduction during normal operation.
The device operates across -65 °C to +185 °C junction temperature range and is rated for 2.5 W steady-state power dissipation on infinite heatsink at 75 °C ambient. It meets MSL Level 1 per J-STD-020 and passes JESD201 Class 2 whisker testing due to its HE3 suffix designation.

|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, and position sensors in powertrain modules exposed to load dump and ISO 7637-2 transients. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between sensor output and microcontroller ADC input to clamp surges before signal conditioning circuitry.

IC Role / Device Role / Timing Role: Low-capacitance transient suppressor mounted directly at MCU pin to minimize trace inductance and ensure sub-nanosecond response. Use Value: Prevents latch-up or permanent damage to MCU I/O structures without degrading signal rise/fall times due to minimal parasitic capacitance. |
| ADAS Camera Interface | Body Control Module (BCM) LIN Bus |
Use Scenario: Shielding MIPI CSI-2 differential pairs in surround-view camera modules from ESD events during assembly and field operation. IC Role / Device Role / Timing Role: Discrete TVS pair (one per line) placed adjacent to connector to absorb fast-rising ESD pulses before reaching serializer IC.

Use Scenario: Protecting LIN transceiver inputs in door modules and seat controllers subjected to battery disconnect transients and electrostatic discharge. IC Role / Device Role / Timing Role: Unidirectional TVS connected between LIN bus line and ground to shunt energy while preserving dominant/recessive voltage thresholds. Use Value: Clamps to ≤16.2 V without affecting LIN physical layer compliance (dominant ≤12 V, recessive ≥8.5 V). |
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 | Higher VBR (11.1–12.3 V), lower IPPM (15.7 A), SMA package (2.3 mm height) | Lacks AEC-Q101 qualification and JESD201 Class 2 whisker rating; not automotive-grade | Acceptable for industrial sensor protection where automotive reliability is not required |
| TPSMP11AHE3/84A | Narrower VBR range (10.5–11.6 V), identical package and clamping (15.6 V), same AEC-Q101 qualification | Better suited for tighter 9–10 V supply rails where margin to VBR min must exceed 0.5 V | Preferred when system VWM is fixed at 9.0 V and higher VBR consistency is critical |
Compared with SMAJ10A, TPSMP11HE3/84A delivers automotive-grade reliability and lower profile; compared with TPSMP11AHE3/84A, it offers wider VBR tolerance for cost-sensitive designs accepting looser voltage margin control.

FAQ
What is the clamping voltage of the TPSMP11HE3/84A under maximum surge conditions?
The TPSMP11HE3/84A has a maximum clamping voltage (VC) of 16.2 V at its rated peak pulse current (IPPM) of 18.5 A, measured using a 10/1000 µs waveform. This value ensures protected circuits remain within safe voltage limits during standardized automotive transients such as ISO 7637-2 Pulse 5a. The TPSMP11HE3/84A maintains this clamping performance across its full operating temperature range.
Is the TPSMP11HE3/84A qualified for automotive use?
Yes, the TPSMP11HE3/84A is AEC-Q101 qualified and designated as high-reliability/automotive grade per its HE3 suffix. It undergoes rigorous stress testing including temperature cycling, humidity bias, and mechanical shock, and meets JESD201 Class 2 whisker resistance requirements. The TPSMP11HE3/84A is intended for under-hood and chassis-mounted applications where extended lifetime and thermal stability are mandatory.
What does the "HE3/84A" suffix indicate in TPSMP11HE3/84A?
The "HE3" suffix denotes RoHS-compliant, high-reliability construction with matte tin-plated leads that pass J-STD-002 solderability and JESD201 Class 2 whisker testing. The "84A" refers to the preferred packaging code: 7-inch plastic tape-and-reel with 3000 units per reel. This packaging format supports automated SMT placement and is optimized for high-volume automotive manufacturing. The TPSMP11HE3/84A uses this exact delivery mode.
How does the DO-220AA package of the TPSMP11HE3/84A compare to SMA or SMB packages?
The DO-220AA (SMP) package of the TPSMP11HE3/84A measures just 1.0 mm in height-less than half the height of standard SMA (2.3 mm) or SMB (2.2 mm) packages-while maintaining comparable power handling. Its low profile enables placement beneath connectors or in tight gaps on multi-layer automotive PCBs. Unlike SMA/SMB, DO-220AA features optimized thermal pad layout per Vishay's recommended footprint for enhanced surge energy dissipation. The TPSMP11HE3/84A leverages this advantage for space-constrained ADAS modules.
What is the maximum operating junction temperature for the TPSMP11HE3/84A?
The TPSMP11HE3/84A has a maximum junction temperature (TJ) rating of +185 °C, validated per AEC-Q101 test conditions. This allows direct placement near heat sources such as power regulators or motor drivers in engine control units without derating concerns. The device sustains full electrical specifications up to this limit, and its thermal resistance (RθJA) is characterized on FR-4 PCBs with Vishay's minimum recommended copper pad layout. The TPSMP11HE3/84A achieves this performance via its patented PAR chip construction and thermally efficient DO-220AA package.
