Product details
Overview
TPSMP12AHM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability overvoltage protection of signal lines and power rails. It features 11.4 V to 12.6 V breakdown voltage (VBR), 10.2 V stand-off voltage (VWM), 18.0 A peak pulse current (IPPM), 16.7 V clamping voltage (VC) at IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the TPSMP12AHM3/84A datasheet, TPSMP12AHM3/84A pinout, TPSMP12AHM3/84A application, or TPSMP12AHM3/84A equivalent, this device delivers low-profile (1.0 mm height), high-power-density surge suppression with MSL Level 1 moisture sensitivity, TJ = 185 °C operation, and optimized junction passivation for robust ESD/EMI resilience in space-constrained automotive and industrial PCBs.
Technical Context
The TPSMP12AHM3/84A implements a passivated anisotropic rectifier structure enabling fast response time (<1 ns) and low incremental surge resistance. Its unidirectional configuration provides forward conduction capability while clamping reverse transients above VBR, with thermal design validated for continuous operation up to 185 °C junction temperature.
Rated for 300 W peak pulse power (10/1000 µs waveform), it achieves 16.7 V clamping at 18.0 A with only 1.0 µA max reverse leakage at VWM (10.2 V), supporting stable protection in low-leakage sensor interfaces and 12 V automotive subsystems without compromising signal integrity.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A-E3/5AT | DO-214AC (SMA) package; 12.2–13.5 V VBR; 15.4 V VC @ 15.6 A; 400 W PPPM | Higher clamping voltage and larger footprint; less suitable for ultra-thin automotive modules | Preferred where higher surge rating outweighs height constraints and board space permits SMA layout |
| TPSMA6.8A-Q | Automotive-grade SMA package; 6.45–7.14 V VBR; 10.5 V VC @ 26.5 A; 300 W PPPM | Lower voltage rating; not interchangeable for 12 V rail protection without redesign | Select only for sub-9 V systems requiring tighter VWM/VBR margin and same AEC-Q101 compliance |
Compared with SMAJ12A-E3/5AT and TPSMA6.8A-Q, the TPSMP12AHM3/84A offers superior height efficiency (1.0 mm vs. 2.3 mm), tighter VBR tolerance (±5 %), and identical AEC-Q101 qualification-making it optimal for next-gen compact automotive electronics where thermal density and board real estate are critical.

FAQ
What is the breakdown voltage range of the TPSMP12AHM3/84A?
The TPSMP12AHM3/84A has a specified breakdown voltage (VBR) range of 11.4 V to 12.6 V at 1.0 mA test current, ensuring consistent triggering behavior across manufacturing lots and temperature extremes. This range allows the TPSMP12AHM3/84A to reliably activate above nominal 12 V system voltages while avoiding premature conduction during normal operation or minor transients.
Is the TPSMP12AHM3/84A suitable for automotive applications?
Yes, the TPSMP12AHM3/84A is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature, making it fully suitable for under-hood and chassis-mounted automotive applications. Its DO-220AA package, MSL Level 1 rating, and halogen-free, RoHS-compliant construction align with automotive supply chain requirements, and the TPSMP12AHM3/84A is explicitly listed in Vishay's automotive-grade product portfolio.
What is the clamping voltage of the TPSMP12AHM3/84A at its rated peak pulse current?
The TPSMP12AHM3/84A exhibits a maximum clamping voltage (VC) of 16.7 V at its rated peak pulse current (IPPM) of 18.0 A under 10/1000 µs waveform conditions. This value ensures downstream components-such as microcontrollers, transceivers, or driver ICs-are exposed to no more than 16.7 V during worst-case surge events, preserving functional safety margins in 12 V systems.
Does the TPSMP12AHM3/84A have polarity marking, and how is it identified?
Yes, the TPSMP12AHM3/84A uses a color band to denote the cathode terminal, consistent with industry-standard diode polarity identification. The band is located at one end of the DO-220AA (SMP) package body, and the opposite end is the anode. This marking enables correct orientation during automated placement and manual inspection, ensuring proper unidirectional clamping functionality in circuit designs using the TPSMP12AHM3/84A.
What packaging format is supplied for the TPSMP12AHM3/84A?
The TPSMP12AHM3/84A is supplied in 7-inch diameter plastic tape and reel format, with a base quantity of 3000 units per reel (package code 84A). This format supports high-speed pick-and-place assembly and complies with EIA-481 standards, ensuring compatibility with standard SMT production lines handling the TPSMP12AHM3/84A.
