Product details
Overview
TPSMP16AHM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability automotive and industrial circuit protection. It features a 15.2 V to 16.8 V breakdown voltage (VBR), 400 W peak pulse power (PPPM), 13.6 V stand-off voltage (VWM), 1.0 µA max reverse leakage at VWM, and clamps to 22.5 V at 17.8 A peak surge current - ideal for safeguarding 12 V automotive signal lines and microcontroller I/O pins.
For engineers reviewing the TPSMP16AHM3/84A datasheet, TPSMP16AHM3/84A pinout, TPSMP16AHM3/84A application, or TPSMP16AHM3/84A equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, low-profile 1.0 mm height, MSL Level 1 reflow compatibility, and unidirectional polarity with cathode band marking - all critical for under-hood automotive electronics and space-constrained PCB layouts.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced surges, and load-dump transients. Its unidirectional configuration provides forward conduction capability while maintaining precise reverse standoff and clamping behavior.
The device operates across -65 °C to +185 °C junction temperature range and is rated for 40 A non-repetitive forward surge current (IFSM) with 2.5 V max forward voltage at 25 A - supporting robust protection in high-energy transient environments without compromising system-level signal integrity.

Pinout & Package
TPSMP16AHM3/84A is a two-terminal unidirectional TVS diode in DO-220AA (SMP) surface-mount package. Polarity is marked by a cathode band on the case end; the terminal adjacent to the band is the cathode, and the opposite terminal is the anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive input terminal in forward bias; connects to protected line or ground return path | Completes conduction path during transient overvoltage events when cathode-to-anode voltage exceeds VBR |
| Cathode | Negative reference terminal; marked by color band | Serves as the reference node for clamping - connected to system ground or lower-potential rail to shunt surge current safely |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock per JESD47 |
| Junction passivation optimized design | Reduces leakage drift and improves long-term stability under high-temperature bias stress |
| MSL Level 1 (260 °C peak) | Enables standard lead-free reflow assembly without moisture sensitivity concerns or baking requirements |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD ±8 kV contact discharge) |
| Very fast response time | Sub-nanosecond turn-on ensures clamping activation before sensitive ICs experience overstress |

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-E3/5AT | DO-214AC (SMA) package; 16.7 V VBR min; 400 W PPPM; 23.5 V VC @ 17.1 A | Higher profile (2.29 mm vs. 1.0 mm); less suitable for ultra-thin automotive modules | Select when legacy SMA footprint exists and board height constraints are relaxed |
| TPSMA6.8A-Q | AEC-Q101 qualified; DO-214AC; lower VBR (6.45–7.14 V); 300 W PPPM; 10.5 V VC | Designed for 5 V logic rail protection; incompatible with 12 V system clamping requirements | Choose only for sub-10 V signal line protection where tighter VBR tolerance is required |
Compared with SMAJ16A-E3/5AT and TPSMA6.8A-Q, the TPSMP16AHM3/84A offers superior board-space efficiency and thermal performance in automotive under-hood applications due to its DO-220AA package, 185 °C rating, and optimized surge resistance - making it the preferred choice where height, reliability, and 12 V system compatibility are jointly constrained.

FAQ
What is the exact breakdown voltage range specified for TPSMP16AHM3/84A?
The TPSMP16AHM3/84A has a guaranteed breakdown voltage (VBR) range of 15.2 V to 16.8 V at 1.0 mA test current, as confirmed in the Vishay datasheet revision 22-Jul-16 (Document Number: 88471). This range ensures consistent triggering behavior across production lots while accommodating 12 V system tolerances and transient margin requirements.
Is TPSMP16AHM3/84A suitable for bidirectional transient protection?
No, TPSMP16AHM3/84A is strictly unidirectional. Its electrical characteristics - including forward voltage (2.5 V at 25 A), reverse standoff (13.6 V), and clamping behavior - are defined only for cathode-to-anode polarity. For bidirectional protection, a separate TVS array or back-to-back configuration would be required; the TPSMP16AHM3/84A itself does not support symmetrical clamping.
Does TPSMP16AHM3/84A meet automotive qualification standards?
Yes, TPSMP16AHM3/84A is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials. It is rated for operation from -65 °C to +185 °C junction temperature and passes MSL Level 1 reflow per J-STD-020 - fulfilling core reliability requirements for automotive powertrain, body, and infotainment systems as documented in the official Vishay specification.
What is the maximum clamping voltage of TPSMP16AHM3/84A under surge conditions?
The TPSMP16AHM3/84A clamps to a maximum of 22.5 V at its rated peak pulse current of 17.8 A (10/1000 μs waveform). This value is measured and guaranteed per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuitry during standardized surge events - critical for ensuring downstream ICs remain within their absolute maximum ratings.
Can TPSMP16AHM3/84A be used in automated SMT assembly processes?
Yes, TPSMP16AHM3/84A is fully compatible with automated surface-mount assembly. Its DO-220AA (SMP) package features matte tin-plated leads solderable per J-STD-002 and JESD 22-B102, meets MSL Level 1 (peak reflow temperature 260 °C), and is supplied in 7" tape-and-reel format (84A packaging code) - enabling direct integration into high-volume pick-and-place manufacturing lines without process modification.
