Product details
Overview
TPSMP11AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the PAR® family, designed for high-reliability automotive and industrial circuit protection. It features a 10.5 V breakdown voltage (VBR), 9.4 V stand-off voltage (VWM), 19.2 A peak pulse current (IPPM), 15.6 V clamping voltage (VC) at IPPM, and operates up to +185 °C junction temperature - ideal for protecting sensor signal lines and drive transistors against ESD and surge events.
For engineers reviewing the TPSMP11AHM3_A/H datasheet, TPSMP11AHM3_A/H pinout, TPSMP11AHM3_A/H application, or TPSMP11AHM3_A/H equivalent, this page delivers verified electrical specs, SMP (DO-220AA) package details, AEC-Q101 qualification status, clamping performance under 10/1000 µs surges, and real-world use cases in automotive ECUs and industrial I/O modules.
Technical Context
The TPSMP11AHM3_A/H employs passivated anisotropic rectifier technology with junction passivation optimized for stable avalanche behavior and low incremental surge resistance. Its unidirectional architecture enables precise reverse-biased clamping during transient overvoltage events on power or signal rails.
Rated for 10.5 V (min) to 11.6 V (max) breakdown at 1 mA test current, it delivers 15.6 V clamping at 19.2 A (10/1000 µs), with <2.0 µA reverse leakage at VWM = 9.4 V and <10 µA at 150 °C - confirming suitability for high-temperature automotive environments per AEC-Q101.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 10.5 V / 11.6 V at 1 mA - defines reliable avalanche initiation threshold for consistent clamping onset |
| VWM | 9.4 V - maximum continuous reverse operating voltage before leakage exceeds 2.0 µA |
| VC @ IPPM | 15.6 V at 19.2 A (10/1000 µs) - limits protected IC voltage during worst-case surge |
| PPPM | 300 W - peak pulse power handling capacity for short-duration transients |
| TJ max. | +185 °C - enables operation in under-hood automotive locations without derating |
| Package | SMP (DO-220AA) - ultra-low-profile (1.0 mm typical height), MSL Level 1, halogen-free, RoHS-compliant |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A | Same VBR range (10.5–11.6 V), but lower PPPM = 400 W only at ≥13 V VBR; rated for 100 W at 11 V, higher VC = 18.2 V | Less effective clamping margin for 3.3 V/5 V logic interfaces due to higher VC | Acceptable where surge energy is lower and layout allows higher clamping voltage |
| TPSMAJ11A | Same DO-214AC (SMA) package; identical VBR/VWM, but VC = 18.2 V and IPPM = 22.0 A at same PPPM | Larger footprint (2.54 mm pitch vs. SMP's 2.67 mm), less suitable for space-constrained automotive modules | Preferred when legacy SMA footprint compatibility is required and height >1.0 mm is acceptable |
Compared with SMAJ11A and TPSMAJ11A, the TPSMP11AHM3_A/H delivers tighter clamping (15.6 V vs. ≥18.2 V), lower profile (1.0 mm), and superior thermal robustness (185 °C vs. 150 °C), making it optimal for next-generation automotive sensor nodes and compact industrial drives.

FAQ
What is the clamping voltage of the TPSMP11AHM3_A/H at its rated peak pulse current?
The TPSMP11AHM3_A/H has a maximum clamping voltage (VC) of 15.6 V at 19.2 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and ensures protected circuits remain below critical voltage thresholds during surge events. The TPSMP11AHM3_A/H achieves this with low incremental surge resistance, minimizing overshoot beyond the specified VC.
Is the TPSMP11AHM3_A/H qualified for automotive applications?
Yes, the TPSMP11AHM3_A/H is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature. It meets automotive reliability requirements including temperature cycling, highly accelerated life testing (HALT), and ESD immunity per JESD22-A114. The TPSMP11AHM3_A/H is explicitly listed in Vishay's AEC-Q101 qualified product list for transient voltage suppression in engine control, body electronics, and ADAS subsystems.
What package type does the TPSMP11AHM3_A/H use, and what are its key mechanical attributes?
The TPSMP11AHM3_A/H uses the SMP (DO-220AA) package: a low-profile surface-mount outline with 2.67 mm length, 1.65 mm width, and 1.0 mm typical height. It features matte tin-plated terminals compliant with J-STD-002 and JESD22-B102, MSL Level 1 rating, and UL 94 V-0 molding compound. The TPSMP11AHM3_A/H's compact size supports automated placement in high-density PCB layouts common in automotive modules.
How does the TPSMP11AHM3_A/H compare to standard SMA-package TVS diodes in terms of thermal performance?
The TPSMP11AHM3_A/H offers superior thermal performance versus SMA-package alternatives due to its optimized thermal path in the SMP (DO-220AA) case and 185 °C maximum junction temperature rating. While SMA devices typically max out at 150 °C, the TPSMP11AHM3_A/H sustains full power derating up to +175 °C ambient when mounted on 5.0 mm × 5.0 mm copper pads - a critical advantage in under-hood automotive applications where ambient temperatures exceed 125 °C.
What is the reverse leakage current specification for the TPSMP11AHM3_A/H at its stand-off voltage?
The TPSMP11AHM3_A/H specifies a maximum reverse leakage current (IR) of 2.0 µA at VWM = 9.4 V and 25 °C, and ≤10 µA at the same voltage and 150 °C. This low leakage ensures minimal power loss and signal distortion in always-on sensor interfaces. The TPSMP11AHM3_A/H maintains this performance across its full operating temperature range, supporting precision analog designs in automotive and industrial systems.
