Product details
Overview
TPSMC13AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-reliability overvoltage protection of sensitive electronics. It features 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 μs), 18.2 V maximum clamping voltage at 82.4 A peak surge current, and operates up to +185 °C junction temperature - ideal for automotive power line and sensor interface protection.
For engineers reviewing the TPSMC13AHE3/57T datasheet, TPSMC13AHE3/57T pinout, TPSMC13AHE3/57T application, or TPSMC13AHE3/57T equivalent, key selection criteria include its AEC-Q101 qualification, unidirectional polarity, low clamping ratio (VC/VBR ≈ 1.40), MSL Level 1 rating, and compatibility with high-temperature PCB reflow profiles up to 260 °C.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable breakdown characteristics across temperature and lifetime. Its 185 °C maximum junction temperature and AEC-Q101 qualification confirm suitability for under-hood automotive environments and industrial control systems requiring extended thermal margin.
The device exhibits fast response time (<1 ns), low incremental surge resistance, and excellent clamping performance under 10/1000 μs transients. Its unidirectional configuration provides robust forward conduction capability (IFSM = 200 A, VF = 3.5 V @ 100 A), enabling effective suppression of both positive-going surges and reverse-biased leakage control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 V / 13.0 V / 13.7 V - ensures precise triggering above system operating voltage while accommodating process variation |
| VWM | 11.1 V - maximum continuous reverse voltage before leakage exceeds 2.0 μA, compatible with 12 V nominal supply rails |
| VC @ IPPM | 18.2 V - clamps 82.4 A surge to safe levels, limiting downstream IC stress to <18.2 V during transient events |
| PPPM | 1500 W - handles high-energy transients per ISO 7637-2 Pulse 1/2a/5a without degradation |
| TJ max. | +185 °C - supports operation in engine control units, motor drivers, and other high-ambient-temperature locations |
| Polarity | Unidirectional - protects against positive transients only; requires external circuit design for bidirectional immunity |
| MSL Level | Level 1 (J-STD-020) - allows unlimited floor life and standard reflow without baking preconditioning |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, matte tin-plated terminals, cathode indicated by color band. Dimensions: 7.11 mm × 6.22 mm × 2.90 mm (L × W × H). Complies with UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction or clamping | Connected to protected line (e.g., 12 V rail); conducts surge current into ground path during overvoltage |
| Cathode | Current exit terminal; marked by color band | Connected to system ground or low-impedance return; defines unidirectional clamping direction |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation optimized design | Enables stable VBR drift <±5% over 1000 hrs at 150 °C, critical for long-life automotive modules |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD per AEC specification |
| 1500 W peak pulse power (10/1000 μs) | Withstands ISO 7637-2 Pulse 5a (500 V/2 Ω) on 12 V systems without failure |
| Low clamping ratio (VC/VBR = 1.40) | Minimizes voltage overshoot during clamping, reducing risk of latch-up or gate oxide damage in MOSFETs/ICs |
| MSL Level 1, 260 °C peak reflow | Eliminates pre-bake requirement and enables direct placement into high-volume SMT lines |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs, body control modules, and lighting drivers from load dump and inductive switching transients.

IC Role / Device Role / Timing Role: Mounted across motor terminals to clamp inductive kickback during PWM switching. Use Value: Withstands 200 A non-repetitive surge (8.3 ms half-sine), preventing MOSFET avalanche failure and extending motor driver lifespan. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Lower PPPM (400 W), same VBR range, SMA package (smaller footprint, lower thermal mass) | Not AEC-Q101 qualified; limited to consumer/industrial use below 150 °C ambient | Select when cost or board space is prioritized over automotive reliability and high-energy surge handling |
| TPSMC13AHM3/57T | Identical electrical specs; halogen-free molding compound and JESD201 Class 2 whisker resistance (vs. HE3's standard RoHS) | Required for strict environmental compliance (e.g., EU automotive Tier 1 supply chains with halogen bans) | Choose HM3 when halogen-free certification and enhanced whisker resistance are mandated by OEM specifications |
Compared with SMAJ13A and TPSMC13AHM3/57T, the TPSMC13AHE3/57T delivers superior energy handling (1500 W vs. 400 W) and automotive qualification, making it the preferred choice for safety-critical 12 V systems where transient robustness and long-term reliability are non-negotiable.

FAQ
What is the maximum clamping voltage of the TPSMC13AHE3/57T and under what test condition?
The TPSMC13AHE3/57T has a maximum clamping voltage (VC) of 18.2 V, measured at its peak pulse current (IPPM) of 82.4 A using the standardized 10/1000 μs double-exponential waveform. This value is guaranteed across the full operating temperature range and reflects worst-case clamping performance during high-energy transients such as load dump or inductive switching events.
Is the TPSMC13AHE3/57T qualified for automotive applications?
Yes, the TPSMC13AHE3/57T is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's official datasheet (Document Number: 88407). This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for under-hood and chassis-mounted automotive electronics.
What does the "HE3" suffix indicate in TPSMC13AHE3/57T?
The "HE3" suffix in TPSMC13AHE3/57T denotes a RoHS-compliant, AEC-Q101-qualified variant with matte tin-plated leads that meet J-STD-002 and JESD 22-B102 solderability requirements. It also satisfies JESD 201 Class 2 whisker resistance testing, ensuring long-term interconnect reliability in high-vibration automotive environments.
What is the standoff voltage (VWM) of the TPSMC13AHE3/57T and why is it important?
The TPSMC13AHE3/57T has a standoff voltage (VWM) of 11.1 V, meaning it remains in high-impedance state with leakage <2.0 μA up to this reverse voltage. This value is critical for compatibility with 12 V nominal systems: it avoids false triggering during normal operation while allowing sufficient margin below the 13.0 V breakdown threshold to ensure reliable surge detection.
Can the TPSMC13AHE3/57T be used in bidirectional protection circuits?
No, the TPSMC13AHE3/57T is unidirectional only, as explicitly stated in the Vishay datasheet. It protects against positive transients on the anode-to-cathode path but offers no clamping for negative excursions. For bidirectional protection, a separate device such as a TPSMC13CA or a back-to-back configuration would be required - the TPSMC13AHE3/57T alone cannot fulfill that function.
