Product details
Overview
TPSMP24AHE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, with 22.8 V to 25.2 V breakdown voltage (VBR), 33.2 V clamping voltage (VC) at 12.0 A peak pulse current, and 400 W peak pulse power rating for VBR ≥ 13 V. It protects signal lines and ICs in automotive sensor units and electronic control modules.
For engineers reviewing the TPSMP24AHE3/84A datasheet, TPSMP24AHE3/84A pinout, TPSMP24AHE3/84A application, or TPSMP24AHE3/84A 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 JESD22-B102 solderability and JESD201 Class 2 whisker resistance.
Technical Context
The TPSMP24AHE3/84A employs Vishay's patented PAR oxide-passivated chip construction, enabling excellent clamping performance and fast response time under 10/1000 µs transients. Its unidirectional configuration supports DC-biased protection paths with cathode-band polarity marking.
Rated for operation from −65 °C to +185 °C junction temperature, it delivers 2.5 W steady-state power dissipation on infinite heatsink at 75 °C ambient and maintains stable VBR temperature coefficient of 0.094 %/°C across its operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V - Ensures reliable triggering above circuit stand-off voltage of 20.5 V while avoiding false trips during normal operation. |
| VC @ IPPM | 33.2 V at 12.0 A - Limits transient-induced overvoltage to safe levels for downstream 24 V automotive ICs and transistors. |
| PPPM | 400 W - Sustains high-energy ESD and load-dump surges per ISO 16750-2 without degradation. |
| IFSM | 40 A - Withstands repetitive 10 ms half-sine surge currents typical in motor drive and relay switching circuits. |
| TJ max. | +185 °C - Enables placement near heat-generating components in engine control units and ADAS modules. |

|---|---|
|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., oxygen, pressure, temperature) from ISO 7637-2 pulses and ESD events. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed directly at connector entry point to shunt transients before reaching sensitive front-end circuitry. Use Value: Maintains signal integrity by limiting clamped voltage to 33.2 V while surviving 400 W surges-critical for 24 V rail compatibility and AEC-Q100 compliance. |
Use Scenario: Safeguarding 24 V supply rails in engine management systems against load dump (ISO 16750-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power input, coordinated with upstream fusing and downstream LDOs/regulators. Use Value: Withstands 40 A surge current and operates up to +185 °C junction temperature-enabling direct placement near high-heat zones in under-hood ECUs. |
| Body Control Module (BCM) Signal Lines | ADAS Camera Power Interface |
|
Use Scenario: Shielding LIN bus communication lines and door actuator driver outputs from battery reverse polarity and jump-start transients. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed adjacent to microcontroller GPIO pins and driver IC outputs. Use Value: 1.0 mm profile allows routing under connectors; matte tin terminations ensure long-term solder joint reliability in thermal-cycling environments. |
Use Scenario: Protecting 12 V camera power input in forward-facing ADAS cameras exposed to harsh automotive transients and ESD. IC Role / Device Role / Timing Role: First-line transient suppression before DC-DC converter input stage, reducing stress on downstream filtering and regulation. Use Value: 400 W peak power rating and 0.094 %/°C VBR tempco ensure consistent clamping behavior across −40 °C to +105 °C ambient conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | DO-214AC (SMA) package; 24 V nominal VBR, 38.9 V VC at 10.3 A; 400 W PPPM; not AEC-Q101 qualified. | Larger 2.3 mm height limits use in ultra-thin modules; lacks automotive qualification and JESD201 whisker testing. | Select SMAJ24A only for cost-sensitive non-automotive industrial applications where AEC-Q101 and MSL Level 1 are not required. |
| TPSMD24A | DO-214AB (SMC) package; same VBR/VC specs; 500 W PPPM; AEC-Q101 qualified; 2.3 mm height. | Higher surge capability but 2.3× taller profile; unsuitable for PCBs with strict Z-axis constraints like camera modules or miniaturized sensors. | Choose TPSMD24A when higher energy handling is needed and board height permits; otherwise TPSMP24AHE3/84A remains optimal for space-limited automotive designs. |
Compared with SMAJ24A and TPSMD24A, the TPSMP24AHE3/84A uniquely combines AEC-Q101 qualification, 1.0 mm profile, and 400 W surge capability-making it the only option that satisfies both mechanical envelope and automotive reliability requirements simultaneously.

The TPSMP24AHE3/84A has a guaranteed breakdown voltage (VBR) range of 22.8 V to 25.2 V at 1 mA test current, measured per ANSI/IEEE C62.35. This ensures robust triggering above the 20.5 V stand-off voltage while maintaining margin against normal operating fluctuations in 24 V automotive systems.
Is TPSMP24AHE3/84A qualified for automotive use?
Yes, the TPSMP24AHE3/84A is AEC-Q101 qualified and rated for automotive applications. Its construction, testing, and packaging-including JESD201 Class 2 whisker resistance and MSL Level 1 reflow compatibility-meet stringent automotive reliability requirements for under-hood and cabin-mounted electronics.
What is the clamping voltage of TPSMP24AHE3/84A at maximum surge current?
The TPSMP24AHE3/84A clamps to a maximum of 33.2 V at its rated peak pulse current of 12.0 A (10/1000 µs waveform). This value is verified per Fig. 1 and Fig. 3 in Vishay document 88471 and ensures protected ICs remain within safe operating voltage limits during ISO 7637-2 and IEC 61000-4-5 transients.
What package type does TPSMP24AHE3/84A use?
The TPSMP24AHE3/84A uses the DO-220AA (SMP) surface-mount package, measuring 3.61 mm × 2.18 mm × 1.0 mm. Its ultra-low profile and matte tin-plated leads comply with J-STD-002 and JESD22-B102, supporting automated placement and lead-free reflow in high-volume automotive manufacturing.
Does TPSMP24AHE3/84A have polarity marking?
Yes, the TPSMP24AHE3/84A features a visible cathode band on the molded case, indicating the cathode terminal. This marking aligns with standard unidirectional TVS orientation practice and must be observed during PCB layout to ensure correct connection to the protected line and proper grounding of the anode.
