Product details
Overview
TPSMP16AHM3_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 overvoltage protection. It features a 15.2 V to 16.8 V breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 400 W peak pulse power (PPPM), 17.8 A peak pulse current (IPPM), and 22.5 V clamping voltage (VC) at IPPM, housed in an SMP (DO-220AA) package with 1.0 mm profile.
For engineers reviewing the TPSMP16AHM3_A/H datasheet, TPSMP16AHM3_A/H pinout, TPSMP16AHM3_A/H application, or TPSMP16AHM3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, low incremental surge resistance, fast response time, and suitability for protecting sensor signal lines and drive transistors in harsh environments.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping performance under repetitive surge events. Its unidirectional polarity and 13.6 V stand-off voltage enable reliable operation across 12 V automotive supply rails while maintaining low leakage (<1 μA at VWM).
The device is rated for 40 A non-repetitive forward surge current (IFSM) and exhibits a temperature coefficient of VBR of +0.086 %/°C - critical for thermal stability in engine bay or powertrain modules where ambient temperatures exceed 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V - ensures robust triggering above nominal 12 V rail while avoiding false trips during load dump transients |
| VWM | 13.6 V - compatible with standard 12 V automotive systems without reverse leakage issues |
| VC @ IPPM | 22.5 V - limits downstream IC voltage stress during ISO 7637-2 Pulse 1/2a/5a events |
| PPPM (10/1000 μs) | 400 W - supports high-energy transients common in motor control and ECU power inputs |
| IPPM | 17.8 A - delivers sufficient surge current handling for CAN/LIN bus line protection |
| TJ max. | 185 °C - enables placement near heat sources (e.g., power MOSFETs, DC-DC converters) without derating |
| Package | SMP (DO-220AA) - ultra-low 1.0 mm height allows routing under connectors and tight board stacking |
Pinout & Package
TPSMP16AHM3_A/H is a two-terminal surface-mount TVS diode in the SMP (DO-220AA) package. The cathode is marked by a color band on the body; the anode and cathode terminals are located at opposite ends of the molded case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction; connected to system ground or low-side reference | Provides return path for surge current during clamping; must be routed with low-inductance ground plane |
| Cathode | Protected line connection; connected to signal or power line requiring transient suppression | Color band identifies this terminal; connects to 12 V rail or sensor output to clamp positive-going surges |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HAST, and mechanical shock per JESD22 standards |
| Junction passivation | Reduces surface leakage and improves long-term stability under humidity and bias stress |
| MSL Level 1 (260 °C) | Enables standard reflow soldering without moisture sensitivity concerns or baking requirements |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ESD, inductive switching) |
| Halogen-free & RoHS-compliant | Meets automotive material compliance requirements (Vishay Doc. #99912) and end-of-life recycling mandates |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

Use Value: 40 A IFSM rating handles repeated motor stall currents; SMP package fits within compact motor driver PCB footprints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Lower PPPM (400 W same), but higher VC (26.0 V), larger SMA package (2.2 mm height), not AEC-Q101 qualified | Suitable for commercial-grade industrial controls; lacks automotive qualification and thermal margin | Select when cost is prioritized over automotive compliance and board height constraints |
| TPSMA6.8A-Q | Same family, lower VBR (6.45–7.14 V), lower PPPM (250 W), identical SMP package and AEC-Q101 status | Designed for 5 V logic rail protection; insufficient clamping margin for 12 V systems | Choose only for sub-9 V applications such as USB-C PD or MCU I/O protection |
Compared with SMAJ16A and TPSMA6.8A-Q, TPSMP16AHM3_A/H offers superior automotive readiness (AEC-Q101 + 185 °C), tighter VBR tolerance, and space savings via its 1.0 mm SMP footprint - making it optimal for next-generation compact, high-temperature ECU designs.

FAQ
What is the clamping voltage of TPSMP16AHM3_A/H at its rated peak pulse current?
The clamping voltage (VC) of TPSMP16AHM3_A/H is 22.5 V when subjected to its maximum peak pulse current (IPPM) of 17.8 A under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuits remain below critical voltage thresholds during standardized surge events like ISO 7637-2 Pulse 5a. The TPSMP16AHM3_A/H maintains this clamping performance across its full operating temperature range.
Is TPSMP16AHM3_A/H qualified for automotive use?
Yes, TPSMP16AHM3_A/H is AEC-Q101 qualified and rated for operation up to 185 °C junction temperature, making it suitable for under-hood and powertrain applications. It meets MSL Level 1 per J-STD-020, supports lead-free reflow up to 260 °C, and is halogen-free and RoHS-compliant per Vishay document #99912. These qualifications are explicitly confirmed in the official Vishay datasheet (Doc. #88471, Rev. 25-Apr-2022) for the TPSMP16AHM3_A/H device.
What package type does TPSMP16AHM3_A/H use, and what are its key mechanical advantages?
TPSMP16AHM3_A/H uses the SMP (DO-220AA) package - a surface-mount, ultra-low-profile case measuring just 1.0 mm in height. Its compact 3.61 mm × 2.18 mm footprint and matte tin-plated leads support automated placement and comply with J-STD-002 solderability standards. The SMP package enables high-density layouts in space-constrained modules such as automotive camera ECUs and portable industrial sensors, where traditional SMA or SMC packages would exceed height budgets.
How does the breakdown voltage tolerance of TPSMP16AHM3_A/H compare to similar TVS diodes?
TPSMP16AHM3_A/H has a specified VBR range of 15.2 V to 16.8 V at 1.0 mA test current - a ±5.3% tolerance around the nominal 16 V rating. This tighter tolerance than many legacy TVS families (e.g., SMAJ series ±10%) improves design margin predictability in 12 V systems, reducing risk of premature conduction during normal operation or inadequate clamping during transients. The value is verified per the Vishay TPSMP6.8A–TPSMP43A datasheet Table on page 2.
Can TPSMP16AHM3_A/H be used in bidirectional configurations?
No, TPSMP16AHM3_A/H is strictly unidirectional and must be oriented with the cathode band toward the protected line. It does not provide symmetrical clamping for negative-going transients. For bidirectional protection, two TPSMP16AHM3_A/H devices may be connected in series opposing configuration, or a dedicated bidirectional TVS (e.g., TPSMP16CA) should be selected. The unidirectional nature is explicitly stated in the "FEATURES" section of the Vishay datasheet (Doc. #88471) and confirmed in the "Polarity" specification.
