Product details
Overview
TPSMA16AHM3_B/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SMA (DO-214AC) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning. It features a 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 μs), 17.8 V maximum clamping voltage at 5.0 A IPPM, and operates up to +185 °C junction temperature.
For engineers reviewing the TPSMA16AHM3_B/H datasheet, TPSMA16AHM3_B/H pinout, TPSMA16AHM3_B/H application, or TPSMA16AHM3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, MSL Level 1 moisture sensitivity, 1.0 W steady-state power dissipation, and compatibility with automotive-grade PCB assembly processes including 260 °C lead-free reflow.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping performance under high-temperature conditions. Its junction design supports operation up to TJ = 185 °C and meets AEC-Q101 stress test requirements for automotive applications.
The device exhibits low incremental surge resistance and fast response time, enabling effective suppression of transient energy before downstream components are damaged. Clamping behavior is characterized per ANSI/IEEE C62.35 standards using 10/1000 μs waveform testing with 0.01% duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nominal) | 16.0 V - Ensures reliable triggering above system operating voltage while maintaining margin against false conduction. |
| VWM | 13.6 V - Maximum continuous reverse voltage the device blocks without significant leakage current. |
| VC @ IPPM | 22.0 V - Clamped voltage seen by protected circuit during 5.0 A transient event, defining worst-case overvoltage exposure. |
| PPPM | 400 W - Peak transient energy absorption capability under standardized 10/1000 μs waveform, critical for surge immunity compliance. |
| TJ max. | +185 °C - Enables use in under-hood automotive environments and high-power industrial enclosures without thermal derating penalties. |
| Polarity | Unidirectional - Provides protection only against positive transients relative to cathode, requiring correct orientation in series with signal/power lines. |
| Package | SMA (DO-214AC) - Standardized surface-mount outline compatible with automated placement and reflow soldering per J-STD-020 MSL Level 1. |
Pinout & Package
SMA (DO-214AC) package with axial leads: cathode marked by color band; anode and cathode terminals aligned along body axis. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per datasheet fig. 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VLINE exceeds VBR. |
| Anode | Reference node | Typically tied to system ground or low-impedance return path; completes clamping loop during overvoltage events. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A | Same VBR (16.0 V), higher PPPM (600 W), larger SMB (DO-214AA) package | Requires larger PCB footprint; better suited for higher-energy transients where space permits | Select SMBJ16A when system-level surge tests exceed 400 W but layout allows SMB footprint. |
| SMCJ16A | Same VBR, PPPM = 1500 W, SMC (DO-214AB) package, higher IFSM (100 A) | Designed for heavy-duty industrial mains protection; over-specified for most signal-line applications | Choose SMCJ16A only when protecting AC/DC front-ends or DC bus rails subject to repetitive high-current surges. |
Compared with SMBJ16A and SMCJ16A, the TPSMA16AHM3_B/H offers optimal balance of compact SMA footprint, AEC-Q101 qualification, and 400 W surge capability-making it ideal for space-constrained automotive and industrial PCBs where MSL Level 1 and halogen-free compliance are mandatory.

FAQ
What is the maximum clamping voltage of the TPSMA16AHM3_B/H under standard test conditions?
The TPSMA16AHM3_B/H has a maximum clamping voltage (VC) of 22.0 V when subjected to a 5.0 A peak pulse current (IPPM) using the 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during transient events and is measured per ANSI/IEEE C62.35 standards. The TPSMA16AHM3_B/H maintains this clamping performance across its full operating temperature range.
Is the TPSMA16AHM3_B/H qualified for automotive applications?
Yes, the TPSMA16AHM3_B/H carries the HM3 suffix, indicating it is halogen-free, RoHS-compliant, and AEC-Q101 qualified. It undergoes stress testing per the AEC-Q101 standard for discrete semiconductors, including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. The TPSMA16AHM3_B/H is rated for junction temperatures up to +185 °C, supporting under-hood automotive deployment.
What does the "HM3" suffix indicate in TPSMA16AHM3_B/H?
The "HM3" suffix in TPSMA16AHM3_B/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from the HE3 version (RoHS-compliant and AEC-Q101 qualified but not halogen-free). Both variants share identical electrical specifications and SMA (DO-214AC) packaging, but HM3 meets additional environmental requirements for restricted substances beyond RoHS.
What is the stand-off voltage (VWM) of the TPSMA16AHM3_B/H, and why is it important?
The stand-off voltage (VWM) of the TPSMA16AHM3_B/H is 13.6 V-the maximum continuous reverse voltage it can block without exceeding 1.0 μA leakage current at 25 °C. This parameter ensures the device remains non-conductive during normal operation while allowing sufficient margin below the 16.0 V nominal breakdown voltage. Selecting a VWM correctly prevents nuisance conduction in 12 V automotive or industrial systems.
Does the TPSMA16AHM3_B/H require special handling during PCB assembly?
No special handling is required beyond standard MSL Level 1 practices: the TPSMA16AHM3_B/H is rated for peak reflow temperatures up to 260 °C per J-STD-020 and does not require baking prior to soldering. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for solderability, and the device passes JESD 201 Class 2 whisker testing. The TPSMA16AHM3_B/H supports standard lead-free reflow profiles used in automotive and industrial manufacturing.
