Product details
Overview
TPSMP11AHE3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for automotive-grade circuit protection. It features a breakdown voltage of 10.5–11.6 V, clamps at ≤15.6 V under 10 A peak pulse current, delivers 300 W peak pulse power (10/1000 µs), and operates from –65 °C to +185 °C junction temperature - used to safeguard sensor signal lines and drive transistors in automotive ECUs.
For engineers reviewing the TPSMP11AHE3/84A datasheet, TPSMP11AHE3/84A pinout, TPSMP11AHE3/84A application, or TPSMP11AHE3/84A equivalent, key selection criteria include its AEC-Q101 qualification, low-profile 1.0 mm height, 9.40 V stand-off voltage, 2.0 µA max reverse leakage at VWM, and compatibility with automated SMT placement on FR-4 PCBs.
Technical Context
The TPSMP11AHE3/84A employs patented PAR oxide-passivated chip construction for stable clamping and low incremental surge resistance. Its unidirectional configuration enables precise anode-to-cathode surge suppression in DC-biased lines, with fast response time (<1 ns) and clamping ratio (VC/VBR) of ~1.37 at rated IPPM.
Rated for MSL Level 1 per J-STD-020 (260 °C reflow peak), it uses matte tin-plated leads compliant with J-STD-002 and JESD22-B102, and passes JESD201 Class 2 whisker testing. The device is RoHS-compliant and qualified to AEC-Q101 for automotive reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 10.5–11.6 V at 1 mA - defines minimum voltage at which TVS initiates conduction during transients |
| Stand-off Voltage VWM | 9.40 V - maximum continuous working voltage before leakage exceeds 2.0 µA |
| Clamping Voltage VC | ≤15.6 V at 10 A (10/1000 µs) - limits downstream voltage stress during surge events |
| Peak Pulse Power PPPM | 300 W - energy-handling capacity for standard 10/1000 µs waveform per JEDEC standards |
| Peak Forward Surge Current IFSM | 40 A - withstands single half-sine 10 ms surge without failure |
| Junction Temperature Range | –65 °C to +185 °C - supports operation in under-hood automotive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | Higher clamping voltage (18.2 V vs. 15.6 V), same DO-214AC package but taller (2.3 mm), 400 W PPPM | Less suitable for low-voltage logic interfaces due to higher VC; better for 24 V systems | Select SMAJ11A only if system margin allows ≥18 V clamping and board height permits 2.3 mm profile. |
| TPSMAJ11A | Same VBR range (10.5–11.6 V), identical clamping (15.6 V), but in DO-214AC package and not AEC-Q101 qualified | Lacks automotive qualification; limited to industrial/commercial use where reliability validation is less stringent | Choose TPSMAJ11A only for non-automotive designs requiring cost optimization without AEC-Q101 compliance. |
Compared with SMAJ11A and TPSMAJ11A, the TPSMP11AHE3/84A offers superior automotive suitability via AEC-Q101 qualification, tighter height constraint (1.0 mm), and lower clamping voltage - critical for protecting modern 3.3 V/5 V automotive microcontrollers without derating headroom.

The TPSMP11AHE3/84A meets all stress test requirements defined in AEC-Q101, making it suitable for engine control, body electronics, and ADAS subsystems.
Does the TPSMP11AHE3/84A have a unidirectional or bidirectional configuration?
The TPSMP11AHE3/84A is a unidirectional TVS diode, as explicitly stated in the "FEATURES" section of its datasheet. It conducts only when cathode voltage exceeds anode voltage by ≥10.5 V, making it appropriate for DC-biased lines such as 12 V supply rails or sensor output signals referenced to ground. Bidirectional variants are not offered in the TPSMPxxA family.
What is the maximum clamping voltage of the TPSMP11AHE3/84A under standard test conditions?
The TPSMP11AHE3/84A has a maximum clamping voltage (VC) of 15.6 V at 10 A peak pulse current with a 10/1000 µs waveform, per the Electrical Characteristics table in Vishay document 88471. This value ensures downstream ICs remain within safe operating voltage limits during transient events like load dump or inductive switching.
Is the TPSMP11AHE3/84A compatible with lead-free reflow soldering processes?
Yes, the TPSMP11AHE3/84A meets MSL Level 1 per J-STD-020 and supports lead-free reflow with a maximum peak temperature of 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102, and it passes JESD201 Class 2 whisker testing - confirming robust solder joint integrity in high-volume SMT assembly.
What does the "HE3/84A" suffix indicate in the TPSMP11AHE3/84A part number?
The "HE3" suffix denotes RoHS-compliant, high-reliability, automotive-grade construction per Vishay's internal coding; "84A" specifies the preferred packaging: 3000-piece 7-inch plastic tape-and-reel delivery mode. This full designation confirms the TPSMP11AHE3/84A is the AEC-Q101-qualified version supplied in industry-standard SMT-ready format.
