Product details
Overview
TPSMP27AHE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, with 25.7 V to 28.4 V breakdown voltage (VBR), 37.5 V clamping voltage (VC) at 10.7 A peak pulse current, and 400 W peak pulse power rating for VBR ≥13 V. It delivers AEC-Q101 qualification, 1.0 mm profile, and RoHS-compliant matte tin terminals for sensor line protection in engine control units.
For engineers reviewing the TPSMP27AHE3/84A datasheet, TPSMP27AHE3/84A pinout, TPSMP27AHE3/84A application, or TPSMP27AHE3/84A equivalent, key selection criteria include unidirectional clamping performance, MSL Level 1 reflow compatibility, junction temperature range (–65 °C to +185 °C), and DO-220AA mechanical footprint for high-density automotive PCB layouts.
Technical Context
This TVS diode uses patented PAR oxide-passivated chip construction to achieve low incremental surge resistance and fast response time under 10/1000 µs transients. Its unidirectional configuration enables precise reverse-biased overvoltage clamping without forward conduction during normal operation.
Rated for 2.5 W steady-state power dissipation on infinite heatsink at 75 °C ambient and 40 A non-repetitive peak forward surge current, the device supports robust protection of sensitive IC inputs and drive transistors in harsh automotive environments where thermal cycling and ESD events coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 25.7 V / 28.4 V - defines minimum trigger threshold and maximum variation across production lot at 1 mA test current |
| VC @ IPPM | 37.5 V at 10.7 A - maximum clamped voltage seen by protected circuit during 10/1000 µs surge, limiting stress on downstream components |
| PPPM | 400 W - peak transient power handling capability for VBR ≥13 V, enabling protection against ISO 7637-2 Pulse 1/2a/5a waveforms |
| IFSM | 40 A - withstands single half-sine 10 ms surge without degradation, critical for load-dump event resilience |
| TJ max. | +185 °C - extended junction temperature rating supports under-hood placement near powertrain electronics |
| VWM | 23.1 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA, ensuring no false triggering during nominal 24 V system operation |
| Package | DO-220AA (SMP) - 3.61 mm × 2.18 mm footprint with 1.0 mm height, optimized for automated SMT placement and space-constrained ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ28A-E3/5AT | Higher VBR (25.2–27.8 V), lower PPPM (400 W same), SMA package (larger footprint, 2.5 mm height) | Less suitable for ultra-low-profile modules; requires larger pad layout and higher standoff clearance | Select when legacy SMA footprint compatibility is required and height constraint is relaxed |
| TPSMA6.8AHE3/A | Lower VBR (6.45–7.14 V), same DO-220AA package, lower PPPM (300 W) | Designed for 5 V logic rail protection; insufficient clamping margin for 24 V systems | Choose only for low-voltage digital I/O protection where 23.1 V VWM is incompatible |
Compared with SMAJ28A-E3/5AT and TPSMA6.8AHE3/A, the TPSMP27AHE3/84A uniquely combines AEC-Q101 qualification, 1.0 mm height, and 23.1 V VWM for direct integration into next-generation 24 V automotive control modules without layout or thermal redesign.

FAQ
What is the clamping voltage of the TPSMP27AHE3/84A at its rated peak pulse current?
The TPSMP27AHE3/84A has a maximum clamping voltage (VC) of 37.5 V at its rated peak pulse current (IPPM) of 10.7 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuits remain within safe operating limits during standardized automotive transients. The TPSMP27AHE3/84A maintains this clamping performance across its full operating temperature range.
Is the TPSMP27AHE3/84A qualified for automotive applications?
Yes, the TPSMP27AHE3/84A is AEC-Q101 qualified and designated as high-reliability/automotive grade (suffix "A"). It undergoes rigorous stress testing including high-temperature operating life, temperature cycling, and ESD per JESD22-A114. The TPSMP27AHE3/84A is explicitly intended for use in engine control units, body control modules, and other safety-critical automotive subsystems.
What does the "HE3/84A" suffix indicate in TPSMP27AHE3/84A?
The "HE3" suffix denotes RoHS-compliant, high-reliability construction with matte tin-plated leads meeting J-STD-002 solderability and JESD22-B102 termination standards. The "84A" indicates the preferred packaging code: 7-inch plastic tape-and-reel with 3000 units per reel, optimized for high-volume SMT assembly. The TPSMP27AHE3/84A is shipped in this format unless otherwise specified.
How does the DO-220AA package of the TPSMP27AHE3/84A compare to SMA in size and thermal performance?
The DO-220AA (SMP) package of the TPSMP27AHE3/84A measures 3.61 mm × 2.18 mm with 1.0 mm typical height-approximately 40% smaller footprint and 60% lower profile than standard SMA. While both offer similar thermal resistance when mounted on 5.0 × 5.0 mm copper pads, the TPSMP27AHE3/84A's compactness enables denser routing in modern ECU designs without sacrificing 400 W pulse power capability.
What is the maximum operating junction temperature for the TPSMP27AHE3/84A?
The TPSMP27AHE3/84A has a maximum operating junction temperature (TJ) of +185 °C, verified per AEC-Q101 stress testing. This rating allows direct placement near high-heat sources such as power MOSFETs or DC-DC converters in under-hood applications. The TPSMP27AHE3/84A sustains full electrical specifications-including 1 µA leakage at VWM-up to this limit, supporting long-term reliability in demanding thermal environments.
