Product details
Overview
TPSMC15HE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, designed for clamping voltage transients on power and signal lines. It features 15 V breakdown voltage (VBR = 13.5–16.5 V), 12.1 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 68.2 A peak pulse current (IPPM), and 22 V maximum clamping voltage (VC) - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power rails.
For engineers reviewing the TPSMC15HE3_A/I datasheet, TPSMC15HE3_A/I pinout, TPSMC15HE3_A/I application, or TPSMC15HE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, DO-214AB mechanical compatibility, and clamping performance under 10/1000 µs surge conditions.
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with sensitive downstream circuitry, activating when reverse voltage exceeds its breakdown threshold. Its passivated anisotropic rectifier structure ensures stable leakage behavior up to 150 °C and supports high-reliability operation in automotive engine control units and industrial motor drives.
The device delivers 1500 W peak pulse power handling with low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD, load dump, and inductive switching transients. It meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 for automotive-grade deployment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 13.5 V / 16.5 V - defines precise voltage threshold at which clamping initiates under 1 mA test current |
| VWM | 12.1 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 22 V - clamped voltage during 68.2 A 10/1000 µs surge, limiting stress on protected ICs |
| PPPM | 1500 W - peak transient energy absorption capability without failure under standardized waveform |
| TJ max. | +185 °C - enables operation in under-hood automotive environments and high-power industrial enclosures |
| Polarity | Unidirectional - protects against reverse-biased transients only; cathode marked by band |
| Package | DO-214AB (SMC) - industry-standard surface-mount outline with 8.0 mm × 8.0 mm copper pad requirement |
Pinout & Package
TPSMC15HE3_A/I uses the DO-214AB (SMC) package: a two-terminal surface-mount case with cathode indicated by a color band. Terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and qualified to JESD 201 Class 2 for whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail); color band identifies this end for correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including powertrain and body electronics under stress testing |
| 185 °C junction rating | Enables reliable operation in high-temperature environments without derating in most layouts |
| 1500 W peak pulse power | Withstands severe load-dump and ISO 7637-2 Pulse 5a transients in 12 V systems |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage margin between clamping and protected device's absolute maximum rating |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and reflow without baking, simplifying SMT manufacturing flow |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply inputs of ECUs and ADAS modules from load dump and jump-start transients. IC Role / Device Role / Timing Role: Voltage-clamping TVS placed directly at connector entry point before DC/DC converter input. Use Value: Limits transient voltage to ≤22 V, preventing damage to 36 V-rated input stages and ensuring system-level ISO 16750-2 compliance. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor on differential or single-ended signal lines near connector interface. Use Value: Clamps sub-100 ns ESD pulses to <22 V while adding <10 pF capacitance, preserving signal integrity up to 1 MHz. |
| Consumer Power Adapter Input Protection | Telecom DC Feeder Line Protection |

IC Role / Device Role / Timing Role: Primary-stage clamping device upstream of DC/DC controller and hot-swap FET. Use Value: Withstands repeated 1500 W surges while holding clamping voltage below 22 V, preserving 30 V-rated MOSFET gate oxide integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Same VWM (12.8 V), slightly higher VC (24.4 V), lower PPPM (400 W), SMA package | Limited to lower-energy transients; unsuitable for automotive load dump per ISO 7637-2 | Select when space-constrained layout requires smaller SMA footprint and surge requirements are ≤400 W |
| 1.5KE15A | Through-hole TO-204AA (DO-41), same VWM/VC, PPPM = 1500 W, but no AEC-Q101 qualification | Not rated for automotive under-hood use; lacks MSL Level 1 and high-temp reliability validation | Choose for cost-sensitive industrial prototypes where reflow compatibility and 185 °C operation are not required |
Compared with SMAJ15A and 1.5KE15A, TPSMC15HE3_A/I uniquely combines AEC-Q101 qualification, DO-214AB surface-mount compatibility, 185 °C operation, and full 1500 W surge capability - making it the only option qualified for production automotive power rail protection without design compromise.

FAQ
What is the breakdown voltage tolerance for TPSMC15HE3_A/I?
The TPSMC15HE3_A/I has a specified breakdown voltage range of 13.5 V to 16.5 V at 1 mA test current (VBR min/max), corresponding to ±10 % tolerance around the nominal 15 V rating. This tolerance is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88407 and applies strictly to the TPSMC15A variant denoted by the "A" suffix in the part number.
Is TPSMC15HE3_A/I RoHS-compliant and lead-free?
Yes, TPSMC15HE3_A/I is RoHS-compliant and lead-free. The "HE3" suffix explicitly indicates Vishay's standard RoHS-compliant construction, and the device uses matte tin-plated leads meeting J-STD-002 solderability requirements. Full compliance documentation is referenced in Vishay's material categorization notice (doc?99912).
Does TPSMC15HE3_A/I support bidirectional transient suppression?
No, TPSMC15HE3_A/I is unidirectional only. The datasheet explicitly states "Available in uni-directional polarity only", and its electrical characteristics (e.g., VWM, VBR) are defined for reverse-bias operation only. For bidirectional protection, engineers must select a dual-diode configuration or alternate part such as TPSMC15CA.
What is the meaning of the "A/I" suffix in TPSMC15HE3_A/I?
The "A" denotes the ±5 % VBR tolerance grade (TPSMC15A), and the "I" specifies the packaging format: 13-inch diameter plastic tape and reel with 3500 units per reel. This ordering code is confirmed in the "Ordering Information" section (page 3) of Vishay document 88407.
Can TPSMC15HE3_A/I be used in place of TPSMC15HE3_A/H?
Yes - TPSMC15HE3_A/I and TPSMC15HE3_A/H share identical electrical and thermal specifications; the only difference is packaging: "I" = 3500-unit 13″ reel, "H" = 850-unit 7″ reel. Both use the same DO-214AB (SMC) package, AEC-Q101 qualification, and RoHS-compliant construction.
