Product details
Overview
TPSMP11AHM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability overvoltage protection of sensitive electronics. It features a 10.5 V to 11.6 V breakdown voltage (VBR), 9.40 V stand-off voltage (VWM), 19.2 A peak pulse current (IPPM), and clamps to ≤15.6 V at rated surge-ideal for protecting automotive sensor signal lines and microcontroller I/O ports against ESD and load dump transients.
For engineers reviewing the TPSMP11AHM3/84A datasheet, TPSMP11AHM3/84A pinout, TPSMP11AHM3/84A application, or TPSMP11AHM3/84A equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-220AA mechanical dimensions, clamping performance under 10/1000 µs surge, and real-world use cases in automotive ECUs and industrial sensor interfaces.
Technical Context
The TPSMP11AHM3/84A employs passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of fast-rising transients such as ISO 7637-2 pulses and IEC 61000-4-2 ESD events. Its unidirectional configuration supports DC-biased signal line protection with minimal leakage (≤2.0 µA at VWM).
Rated for continuous operation up to TJ = 185 °C and qualified per AEC-Q101, the device targets automotive-grade reliability in engine control units, body electronics, and ADAS sensor modules where thermal robustness and long-term stability under cyclic stress are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 10.5 V / 11.6 V - ensures reliable triggering above normal operating voltage while avoiding false trips during ripple or tolerance drift |
| VWM | 9.40 V - maximum continuous reverse voltage before significant leakage; matches 9 V rail systems with margin |
| IPPM (10/1000 µs) | 19.2 A - peak surge current handling capacity under standardized lightning/surge waveform |
| VC @ IPPM | ≤15.6 V - clamped voltage limits stress on downstream ICs (e.g., MCU GPIOs rated for 16 V abs max) |
| PPPM | 300 W - peak pulse power rating confirms suitability for automotive load-dump and ISO 16750-2 Class III/IV events |
| TJ max | 185 °C - enables placement near heat sources (e.g., power stages) without derating concerns in under-hood environments |
| Leakage @ VWM | ≤2.0 µA - negligible standby current draw critical for battery-powered sensor nodes |

IC Role / Device Role / Timing Role: Localized TVS mounted adjacent to connector, shunting >8 kV HBM ESD events away from silicon input structures. Use Value: Achieves <1 ns response and ≤15.6 V clamping, preventing gate oxide damage and system resets during field use. |
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), same DO-214AC package, lower PPPM (400 W vs. 300 W), no AEC-Q101 qualification | General-purpose industrial/commercial use only; unsuitable for automotive qualification requirements | Select SMAJ10A only if AEC-Q101 compliance is not required and higher clamping voltage is acceptable |
| TPSMA6.8A | Lower VBR (6.45–7.14 V), same AEC-Q101 qualification, identical DO-220AA package, 300 W PPPM | Designed for 5 V logic rail protection rather than 9 V sensor interface; incompatible VWM/VBR window for TPSMP11AHM3/84A use cases | Choose TPSMA6.8A only for 5 V systems requiring tighter voltage coordination with TTL/LVCMOS thresholds |
Compared with SMAJ10A and TPSMA6.8A, the TPSMP11AHM3/84A uniquely balances AEC-Q101 compliance, 9.4 V stand-off compatibility with 9 V automotive subsystems, and precise 10.5–11.6 V breakdown targeting sensor signal integrity-making it non-interchangeable without circuit-level validation.

FAQ
What is the breakdown voltage range of the TPSMP11AHM3/84A?
The TPSMP11AHM3/84A has a specified breakdown voltage (VBR) range of 10.5 V to 11.6 V at 1.0 mA test current. This tight tolerance ensures consistent triggering behavior across production lots and temperature extremes, making it suitable for precision 9 V sensor interface protection where overvoltage margin must be tightly controlled without risking false conduction during normal operation.
Is the TPSMP11AHM3/84A qualified for automotive applications?
Yes, the TPSMP11AHM3/84A is AEC-Q101 qualified and rated for continuous operation up to 185 °C junction temperature. It meets automotive reliability standards for use in engine control units, body electronics, and ADAS sensor modules-verified through accelerated life testing, temperature cycling, and humidity bias stress per AEC-Q101 Rev D requirements.
What package type does the TPSMP11AHM3/84A use, and what are its key mechanical features?
The TPSMP11AHM3/84A uses the DO-220AA (SMP) surface-mount package: ultra-low profile (1.0 mm typical height), matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, halogen-free, RoHS-compliant, and MSL Level 1 rated for 260 °C peak reflow. The cathode is marked by a visible color band, and the molding compound meets UL 94 V-0 flammability rating.
How does the clamping voltage of the TPSMP11AHM3/84A compare to its breakdown voltage?
The TPSMP11AHM3/84A clamps to ≤15.6 V at its rated 19.2 A peak pulse current (IPPM), while its breakdown voltage starts at 10.5 V. This 5.1 V differential reflects low dynamic impedance and efficient energy absorption-critical for protecting 16 V absolute-maximum-rated ICs like automotive MCUs and transceivers without exceeding safe voltage thresholds during surge events.
Can the TPSMP11AHM3/84A be used in bidirectional protection configurations?
No, the TPSMP11AHM3/84A is unidirectional only, as confirmed in the Vishay datasheet. It protects against positive transients on a DC-biased line referenced to ground. For bidirectional applications (e.g., AC-coupled data lines), a dedicated bidirectional TVS such as the TPSMD11A or SMAJ11CA would be required-using two unidirectional devices back-to-back is not recommended due to mismatched VBR and inconsistent clamping symmetry.
