Product details
Overview
TPSMP43-E3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-220AA (SMP) package, designed for automotive-grade surge protection with 43 V breakdown voltage (VBR = 38.7–47.3 V), 400 W peak pulse power (10/1000 µs), 6.5 A peak pulse current (IPPM), and clamping voltage of 61.9 V at rated surge. It protects signal lines and ICs in engine control units and ADAS sensors.
For engineers reviewing the TPSMP43-E3/84A datasheet, TPSMP43-E3/84A pinout, TPSMP43-E3/84A application, or TPSMP43-E3/84A equivalent, key selection criteria include unidirectional polarity, DO-220AA mechanical compatibility, 185 °C max junction temperature, RoHS/WEEE compliance, and AEC-Q101 qualification path via HE3 suffix variants.
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 ISO 7637-2 load-dump transients. Its unidirectional configuration supports DC-biased signal line protection without reverse conduction during normal operation.
Rated for 1.0 W steady-state power dissipation on PCB with 5.0 × 5.0 mm copper pads per terminal, it operates across –65 °C to +185 °C and meets MSL Level 1 per J-STD-020C with 260 °C solder dip tolerance for 40 seconds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 38.7 V / 47.3 V - Ensures reliable triggering above system operating voltage while avoiding false clamping during transients. |
| VWM | 34.8 V - Maximum continuous reverse standoff voltage compatible with 32 V automotive systems. |
| IPPM | 6.5 A - Peak surge current capability under 10/1000 µs waveform, validated with derating above 25 °C ambient. |
| PPPM | 400 W - Sustains high-energy transients typical of ISO 16750-2 pulse 5a (load dump) in 12 V architectures. |
| VC @ IPPM | 61.9 V - Clamped voltage limits downstream component stress during full-rated surge event. |
| TJ max | +185 °C - Enables placement near high-temperature zones like powertrain ECUs without thermal derating penalties. |
| IR @ VWM | 1.0 µA - Ultra-low leakage preserves battery life in always-on vehicle networks (e.g., CAN FD wake-up lines). |
Pinout & Package
DO-220AA (SMP) surface-mount package: 1.0 mm typical height, matte tin-plated leads, cathode indicated by color band. Compliant with UL-94V-0 epoxy and J-STD-002B solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during clamping | Connected to protected line; conducts surge current toward ground when VBR exceeded. |
| Cathode | Reverse-biased terminal; marked with band | Connected to system ground or low-impedance return path; defines unidirectional clamping direction. |
Key Features
| Feature | Design Value |
|---|---|
| Very low profile (1.0 mm height) | Enables integration into space-constrained automotive modules such as radar front-ends and camera control units. |
| Patented PAR oxide passivation | Reduces leakage drift over temperature and extends lifetime under repeated surge stress in harsh environments. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 10605 ESD), improving protection margin. |
| MSL Level 1 rating | Eliminates pre-bake requirement before reflow, supporting high-yield automated assembly in Tier-1 production lines. |
| AEC-Q101 qualification path | E3 suffix denotes commercial grade; HE3 suffix variants are qualified for automotive under AEC-Q101, enabling direct upgrade paths. |
Applications
| Engine Control Unit (ECU) Sensor Lines | Automotive Camera Power Input |
|---|---|
Use Scenario: Protecting throttle position sensor and crankshaft position sensor signal lines from load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between sensor output and microcontroller input to clamp surges before signal conditioning circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ43A | DO-214AC (SMA) package; 400 W PPPM; VC = 69.4 V at 5.8 A; 2.5 mm height | Higher clamping voltage and larger footprint limit use in ultra-thin modules like ADAS cameras. | Select SMAJ43A only if board space allows taller profile and higher clamping margin is acceptable. |
| TPSMP43A-E3/84A | Same DO-220AA package; tighter VBR range (40.9–45.2 V); lower VC = 59.3 V at 6.7 A; AEC-Q101 qualified variant | Validated for automotive mission-critical systems requiring AEC-Q101 compliance (e.g., brake-by-wire interfaces). | Choose TPSMP43A-E3/84A when AEC-Q101 qualification and reduced clamping voltage are required for safety-critical functions. |
Compared with SMAJ43A, TPSMP43-E3/84A offers 0.7 mm lower profile and 7.5 V lower clamping, enabling tighter voltage margins in compact automotive electronics; versus TPSMP43A-E3/84A, it trades AEC-Q101 validation for cost-sensitive commercial-tier designs where qualification is not mandated.

FAQ
What is the maximum junction temperature rating for TPSMP43-E3/84A?
The TPSMP43-E3/84A has a maximum junction temperature (TJ) of +185 °C, allowing operation in high-temperature automotive environments such as engine compartments and powertrain control units. This rating is validated per JEDEC standards and enables reliable performance without thermal derating up to 150 °C ambient when mounted on 5.0 × 5.0 mm copper pads.
Does TPSMP43-E3/84A meet AEC-Q101 qualification requirements?
The TPSMP43-E3/84A itself carries the E3 commercial-grade suffix and is not AEC-Q101 qualified; however, the TPSMP43A-E3/84A variant (with HE3 suffix) is fully AEC-Q101 qualified. Engineers requiring automotive qualification should select TPSMP43A-E3/84A, which shares identical DO-220AA packaging and improved VBR tightness (40.9–45.2 V) and lower clamping (59.3 V).
What is the clamping voltage of TPSMP43-E3/84A at its rated peak pulse current?
The TPSMP43-E3/84A clamps to 61.9 V at its rated peak pulse current of 6.5 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and reflects actual voltage seen by downstream circuitry during full-rated surge events, ensuring compatibility with 60 V-rated protection stages in automotive power domains.
How does the DO-220AA package of TPSMP43-E3/84A compare to DO-214AC in size and thermal performance?
The DO-220AA package of TPSMP43-E3/84A measures 1.0 mm typical height versus 2.5 mm for DO-214AC (SMA), reducing vertical space by 60 %. Thermal resistance is optimized via 5.0 × 5.0 mm copper pads per terminal, achieving 1.0 W power dissipation at 50 °C ambient-comparable to SMA packages despite smaller footprint.
Is TPSMP43-E3/84A suitable for protecting CAN FD bus lines?
Yes, TPSMP43-E3/84A is suitable for CAN FD bus protection due to its 34.8 V standoff voltage (VWM), which exceeds the CAN FD common-mode range (±12 V), and 61.9 V clamping voltage that stays below the 70 V absolute maximum rating of most CAN FD transceivers. Its unidirectional configuration avoids interference with bus biasing networks.
