Product details
Overview
TPSMP16AHM3_A/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the PAR® family, designed for high-reliability automotive and industrial surge 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/I datasheet, TPSMP16AHM3_A/I pinout, TPSMP16AHM3_A/I application, or TPSMP16AHM3_A/I equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal derating behavior, clamping performance under 10/1000 µs transients, and direct alternatives for board-level ESD/surge protection in sensor interfaces, power rails, and signal lines.
Technical Context
The TPSMP16AHM3_A/I uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and lightning-induced transients. Its unidirectional configuration supports DC-biased lines such as automotive power supplies and CAN bus receivers.
Rated for TJ = 185 °C operation and qualified to AEC-Q101, it sustains 40 A non-repetitive forward surge current (IFSM) and maintains stable clamping up to 150 °C junction temperature, with <1.0 µA reverse leakage at VWM and 1000 µA at 150 °C - critical for low-power sensor units.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V - defines minimum voltage at which device enters avalanche conduction; ensures reliable triggering above system operating voltage |
| VWM | 13.6 V - maximum continuous reverse voltage before leakage exceeds 1 µA; sets safe operating margin below VBR |
| PPPM | 400 W - peak power dissipation under 10/1000 µs waveform; determines survivability against IEC 61000-4-5 Level 4 surges |
| VC @ IPPM | 22.5 V - clamped voltage during 17.8 A transient; limits stress on downstream ICs like microcontrollers or transceivers |
| IPPM | 17.8 A - peak surge current capability at rated PPPM; correlates directly with energy absorption (E ≈ 0.4 × VC × IPPM × tp) |
| TJ max. | 185 °C - enables use in under-hood automotive modules without thermal derating penalties |
| Package | SMP (DO-220AA) - 3.61 mm × 2.18 mm footprint, 1.0 mm height; compatible with high-speed SMT placement and meets MSL level 1 |
Pinout & Package
TPSMP16AHM3_A/I is a two-terminal unidirectional TVS diode in the SMP (DO-220AA) surface-mount package. The cathode is marked by a color band; polarity must be observed during PCB layout to ensure correct transient shunting path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-impedance return path; completes clamping loop during overvoltage events |
| Cathode | High-side connection point | Connected to protected line (e.g., 12 V rail or sensor output); conducts avalanche current when VIN > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per JESD22 standards |
| 185 °C junction rating | Enables deployment in engine control units and ADAS modules without external heatsinking or derating |
| 1.0 mm profile | Reduces board space and improves airflow in dense power electronics layouts; avoids interference with adjacent tall components |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a), improving protection margin |
| Halogen-free, RoHS-compliant | Meets EU Directive 2011/65/EU and automotive material compliance requirements (Vishay Doc. #99912) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Lower PPPM (400 W vs. 400 W same), but higher VC (25.8 V), larger SMA package (2.5 mm height), not AEC-Q101 qualified | Not suitable for automotive under-hood use due to 150 °C TJ limit and lack of automotive qualification | Select SMAJ16A only for cost-sensitive industrial designs where AEC-Q101 and 185 °C operation are unnecessary |
| TPSMD16A | Same VBR/VWM/VC specs, but DO-214AB package (3.9 mm height), higher thermal mass, lower mounting density | Better for high-energy surge environments (e.g., telecom AC inputs), less suited for space-constrained automotive PCBs | Choose TPSMD16A when board-level thermal management requires greater power dissipation margin over multiple pulses |
Compared with SMAJ16A and TPSMD16A, the TPSMP16AHM3_A/I delivers identical clamping performance in a 1.0 mm low-profile package with AEC-Q101 validation - making it the optimal choice for automotive front-end protection where height, reliability, and qualification are non-negotiable.

FAQ
What is the breakdown voltage tolerance for TPSMP16AHM3_A/I?
The TPSMP16AHM3_A/I has a specified breakdown voltage (VBR) range of 15.2 V to 16.8 V at 1.0 mA test current, representing ±5.3% tolerance around the nominal 16 V rating. This tight distribution ensures consistent triggering behavior across production lots and supports robust design margins in 12 V automotive systems where VBR must exceed VWM (13.6 V) while remaining safely below downstream IC absolute maximum ratings. The TPSMP16AHM3_A/I datasheet confirms this range under "Electrical Characteristics" Table on page 2.
Is TPSMP16AHM3_A/I suitable for bidirectional transient protection?
No, the TPSMP16AHM3_A/I is strictly unidirectional and must be used with correct polarity - cathode connected to the protected line, anode to ground. It does not provide symmetrical clamping for AC or bipolar signals. For bidirectional protection, Vishay offers separate parts like the TPSMP16CA series. Using TPSMP16AHM3_A/I in reverse orientation will result in forward conduction and failure. The device marking code "AZP" and cathode band on the SMP package confirm its unidirectional nature per the TPSMP16AHM3_A/I datasheet Figure 4.
What is the maximum clamping voltage of TPSMP16AHM3_A/I at its rated peak pulse current?
The maximum clamping voltage (VC) of the TPSMP16AHM3_A/I is 22.5 V at its rated peak pulse current (IPPM) of 17.8 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and represents the upper limit of voltage seen by downstream circuitry during worst-case surge events. It is critical for verifying that protected ICs remain within their absolute maximum voltage ratings. The TPSMP16AHM3_A/I datasheet lists this parameter in the "Electrical Characteristics" table on page 2.
Does TPSMP16AHM3_A/I meet automotive qualification standards?
Yes, the TPSMP16AHM3_A/I is fully AEC-Q101 qualified and rated for operation up to 185 °C junction temperature, making it suitable for automotive under-hood and cabin applications. It passes stress tests including temperature cycling, high-temperature operating life, and mechanical shock per AEC-Q101 Rev D. The HM3 suffix explicitly denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. This qualification is documented in the "Features" section and "Ordering Information" of the TPSMP16AHM3_A/I datasheet (Document Number 88471).
What is the thermal derating behavior of TPSMP16AHM3_A/I above 25 °C ambient?
The TPSMP16AHM3_A/I exhibits linear thermal derating of peak pulse power (PPPM) above 25 °C ambient, dropping to approximately 50% of rated 400 W at 125 °C ambient when mounted on a standard FR-4 PCB with 5.0 mm × 5.0 mm copper pads per terminal. Derating follows the curve in Figure 2 of the datasheet, and steady-state power dissipation (PD) is limited to 2.5 W at 75 °C ambient on infinite heatsink. These curves are essential for validating protection performance in high-temperature automotive environments. The TPSMP16AHM3_A/I datasheet provides full derating data on page 3.
