Product details
Overview
TPSMC16AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping fast voltage transients on power and signal lines. It features 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 66.7 A peak pulse current (IPPM), and 22.5 V maximum clamping voltage (VC) - deployed in automotive power rails and industrial sensor interfaces.
For engineers reviewing the TPSMC16AHE3_A/H datasheet, TPSMC16AHE3_A/H pinout, TPSMC16AHE3_A/H application, or TPSMC16AHE3_A/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, and direct replacement guidance for high-reliability overvoltage protection design.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and excellent clamping response under 10/1000 µs transients. Its junction temperature rating of −65 °C to +185 °C enables operation in under-hood automotive environments and industrial control cabinets without thermal derating penalties up to 125 °C ambient.
The device is unidirectional only, with cathode marked by a band, and meets MSL Level 1 per J-STD-020 at 260 °C peak reflow. It is RoHS-compliant and AEC-Q101 qualified - confirmed by the HE3 suffix - making it suitable for automotive ECUs and safety-critical power supply inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 15.2 / 16.0 / 16.8 V - ensures reliable triggering above 13.6 V system operating voltage while avoiding false trips during normal ripple. |
| VWM | 13.6 V - maximum continuous reverse voltage before leakage exceeds 1 µA, compatible with 12 V nominal automotive systems. |
| VC @ IPPM | 22.5 V - clamps 66.7 A transient to safe levels for downstream 24 V-rated ICs and MOSFETs. |
| PPPM | 1500 W - sustains high-energy load dump or inductive switching surges without failure when mounted on 8 mm × 8 mm copper pads. |
| TJ max | +185 °C - supports extended high-temperature operation in engine control modules and industrial motor drives. |
| IFSM | 200 A - withstands 8.3 ms half-sine surge events such as alternator load dump per ISO 7637-2. |
| Leakage @ VWM | 1.0 µA at 25 °C - minimizes standby power loss in always-on automotive subsystems. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, matte tin-plated leads, UL 94 V-0 molding compound. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current return path | Connected to ground or low-impedance reference plane; carries full surge current during clamping. |
| Cathode | Protected line connection | Connected to the line being protected (e.g., 12 V rail); voltage referenced to anode during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for ECU and ADAS power protection. |
| 1500 W peak pulse power | Handles ISO 7637-2 Pulse 5a (load dump) and Pulse 1/2b (inductive switch-off) without degradation when properly mounted. |
| Low clamping ratio (VC/VBR = 1.41) | Minimizes overvoltage stress on downstream components - critical for protecting 24 V logic interfaces and gate drivers. |
| TJ = 185 °C capability | Enables placement near heat sources (e.g., power converters) without thermal shutdown or parameter drift. |
| MSL Level 1 | Allows standard SMT reflow without moisture sensitivity concerns - no baking required prior to assembly. |

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 | Same VBR (16.0 V), lower PPPM (400 W), SMA package (smaller footprint, lower thermal mass). | Limited to lower-energy transients; not AEC-Q101 qualified; unsuitable for automotive under-hood use. | Select when board space is constrained and surge energy is limited to IEC 61000-4-5 Level 3 (0.5 kV). |
| TPSMC16AHE3_A/I | Identical electrical specs and qualification; differs only in tape-and-reel packaging (3500 pcs vs. 850 pcs per reel). | No functional difference; same PCB layout, thermal performance, and reliability. | Choose based on production volume and SMT line feeder compatibility - no design change required. |

FAQ
What is the AEC-Q101 qualification status of TPSMC16AHE3_A/H?
TPSMC16AHE3_A/H is fully AEC-Q101 qualified, as confirmed by the HE3 suffix and documented in Vishay's official qualification reports. This includes testing for temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev D. The qualification applies directly to the TPSMC16AHE3_A/H part number, not just the base TPSMC16A family.
Does TPSMC16AHE3_A/H support bidirectional transient suppression?
No, TPSMC16AHE3_A/H is unidirectional only, as explicitly stated in the "Features" section of the datasheet. It protects against positive transients on the cathode side relative to the anode. For bidirectional protection, two TPSMC16AHE3_A/H devices must be used in series opposition, or a dedicated bidirectional TVS such as SMBJ16CA should be selected.
What is the maximum clamping voltage of TPSMC16AHE3_A/H at its rated peak pulse current?
The maximum clamping voltage (VC) of TPSMC16AHE3_A/H is 22.5 V at IPPM = 66.7 A with a 10/1000 µs waveform. This value is measured under standardized test conditions (mounted on 8.0 mm × 8.0 mm copper pads) and represents the upper bound of voltage seen by downstream circuitry during worst-case surge events.
How does the thermal derating of TPSMC16AHE3_A/H behave above 25 °C ambient?
TPSMC16AHE3_A/H follows the derating curve in Figure 2 of the datasheet: peak pulse power decreases linearly from 100 % at 25 °C to ~50 % at 125 °C ambient. At 150 °C, it retains ~30 % of rated PPPM. This behavior is enabled by its 185 °C maximum junction temperature and is validated for continuous operation in automotive under-hood environments.
Is the SMC (DO-214AB) package of TPSMC16AHE3_A/H compatible with standard reflow profiles?
Yes, TPSMC16AHE3_A/H is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, and whisker resistance meets JESD 201 Class 2 - enabling compatibility with standard lead-free reflow profiles without pre-baking or special handling.
