Product details
Overview
SM15T10AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 10.5 V minimum breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), and 14.5 V maximum clamping voltage (VC) at 103 A peak pulse current - used to protect automotive sensor signal lines and industrial I/O interfaces against lightning-induced and inductive-switching transients.
For engineers reviewing the SM15T10AHE3/57T datasheet, SM15T10AHE3/57T pinout, SM15T10AHE3/57T application, or SM15T10AHE3/57T equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), clamping performance under 10/1000 μs surge, and polarity marking (cathode band), all critical for ESD/surge protection design-in and automotive-grade reliability validation.
Technical Context
The SM15T10AHE3/57T operates as a unidirectional avalanche diode with glass-passivated junction, delivering precise voltage clamping during transient events. Its 10/1000 μs waveform response defines its 1500 W peak pulse power rating and 103 A IPPM, while low inductance and MSL Level 1 moisture sensitivity support high-reliability automated assembly.
Designed for systems where source impedance limits surge current, it fails short-circuit under overstress - a predictable failure mode essential for fault-tolerant protection schemes. The device's 150 °C max junction temperature and -65 °C to +150 °C operating range enable deployment in under-hood automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 8.55 V - Maximum continuous reverse voltage before leakage exceeds 10 μA; sets upper limit for normal circuit operation without conduction. |
| VBR (Breakdown Voltage) | 9.50–10.5 V at 1.0 mA - Confirmed avalanche onset range; ensures reliable triggering above system operating voltage. |
| VC (Clamping Voltage) | 14.5 V at 103 A (10/1000 μs) - Maximum voltage seen by protected IC/MOSFET during worst-case surge; enables safe margin below device absolute max ratings. |
| PPPM (Peak Pulse Power) | 1500 W - Sustained energy absorption capability under standardized lightning-surge waveform; qualifies for IEC 61000-4-5 Level 4 compliance designs. |
| RθJA (Junction-to-Ambient) | 75 °C/W - Thermal resistance on recommended 8.0 mm × 8.0 mm copper pads; determines derating needed above 25 °C ambient. |
| TJ max | 150 °C - Maximum allowable junction temperature; supports operation in engine control units and motor drive PCBs with localized heating. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile plastic case with matte tin-plated leads; meets UL 94 V-0, J-STD-002 solderability, and JESD 201 Class 2 whisker resistance. Cathode identified by molded band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry (unidirectional) | Connected to protected line side; conducts only during reverse-biased transient clamping. |
| Cathode | Reverse-biased terminal (marked with band) | Connected to ground or low-impedance return path; defines clamping polarity and directionality. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces per stress test requirements. |
| 1500 W peak pulse power (10/1000 μs) | Enables robust protection against ISO 7637-2 pulse 1/2a/5a and IEC 61000-4-5 surges without external current limiting. |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage stress on downstream ICs - critical for 3.3 V/5 V logic and automotive CAN/LIN transceivers. |
| MSL Level 1 (260 °C peak) | Permits standard lead-free reflow without preconditioning; eliminates moisture-related popcorning risk in high-volume SMT lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | 600 W PPPM, same VWM/VBR range, SMA package (smaller footprint, lower thermal mass) | Lower surge capacity; suitable only for sub-IEC 61000-4-5 Level 2 threats | Select when board space is constrained and threat level is limited to ESD/EFT, not lightning. |
| SMCJ10A | 1500 W PPPM, identical VWM/VBR/VC, same SMC package but commercial-grade (non-AEC-Q101) | Lacks automotive qualification; not approved for under-hood or safety-critical modules | Choose for cost-sensitive industrial controls where AEC-Q101 is not mandated. |
Compared with SMAJ10A and SMCJ10A, the SM15T10AHE3/57T uniquely combines 1500 W surge capability, AEC-Q101 qualification, and SMC package thermal performance - making it the only option qualified for automotive powertrain and chassis domain controllers requiring validated long-term reliability under thermal cycling and vibration.

FAQ
What is the clamping voltage of SM15T10AHE3/57T at its rated peak pulse current?
The SM15T10AHE3/57T has a maximum clamping voltage (VC) of 14.5 V at 103 A peak pulse current under the 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88380 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events - critical for ensuring compatibility with 12 V and 15 V logic rails.
Is SM15T10AHE3/57T qualified for automotive use?
Yes, SM15T10AHE3/57T is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's SM15T series datasheet (Rev. 09-Jan-2024, Doc. #88380). This qualification covers stress tests including HTGB, HTRB, TCT, and mechanical shock - validating its suitability for engine control, body electronics, and ADAS sensor modules.
What does the "/57T" suffix indicate in SM15T10AHE3/57T?
The "/57T" suffix denotes the preferred packaging configuration: 7-inch diameter plastic tape and reel, with a base quantity of 850 units. This format is optimized for high-speed pick-and-place assembly and aligns with Vishay's standard ordering code structure for SMC-packaged devices.
How does SM15T10AHE3/57T differ from SM15T10A-E3/57T?
SM15T10AHE3/57T includes AEC-Q101 qualification (indicated by "H"), whereas SM15T10A-E3/57T is RoHS-compliant commercial grade only. Both share identical electrical specs and SMC package, but only the HE3 variant is approved for automotive applications requiring stress-tested reliability and extended temperature operation.
What is the thermal resistance of SM15T10AHE3/57T, and how does it affect layout?
The SM15T10AHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. This requires PCB designers to allocate sufficient copper area and avoid thermal bottlenecks - especially in automotive modules where ambient temperatures exceed 85 °C and sustained power dissipation must remain below 6.5 W.
