Product details
Overview
SM15T100AHE3/9AT from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), 137 V clamping voltage at 11.0 A peak pulse current, and 85.5 V stand-off voltage - designed to protect automotive-grade power rails and I/O lines against lightning-induced surges and inductive switching transients.
For engineers reviewing the SM15T100AHE3/9AT datasheet, SM15T100AHE3/9AT pinout, SM15T100AHE3/9AT application, or SM15T100AHE3/9AT equivalent, this AEC-Q101 qualified TVS offers verified clamping performance, low-inductance SMC packaging, and RoHS-compliant matte tin terminals suitable for high-reliability automotive electronics design and industrial power interface protection.
Technical Context
The SM15T100AHE3/9AT operates as a unidirectional avalanche diode with a specified breakdown voltage range of 95.0–105 V at 1.0 mA test current and clamps transients to ≤137 V at 11.0 A (10/1000 μs). Its thermal resistance is 75 °C/W junction-to-ambient (on recommended 8.0 mm × 8.0 mm copper pads) and 15 °C/W junction-to-lead, enabling robust surge handling without external heatsinking under typical PCB layouts.
It features glass passivated chip junction, meets MSL Level 1 per J-STD-020 (260 °C peak reflow), and is qualified to AEC-Q101 - confirming suitability for automotive under-hood and body-control module applications where reliability across -65 °C to +150 °C junction temperature is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 1500 W - sustains single lightning-surge events without degradation when mounted on minimum 8.0 mm × 8.0 mm copper pads |
| Stand-off Voltage (VWM) | 85.5 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA, defining safe operating margin below system rail |
| Clamping Voltage (VC @ IPPM) | 137 V at 11.0 A - limits transient voltage seen by downstream ICs during 10/1000 μs surge, protecting 100 V-rated components |
| Breakdown Voltage (VBR) | 95.0–105 V @ 1.0 mA - precise avalanche onset ensures predictable turn-on timing and minimal overshoot |
| Junction Temperature Range | -65 °C to +150 °C - supports operation in automotive engine compartments and industrial power converters |
| Package | SMC (DO-214AB) - surface-mount, low-profile package compatible with automated placement and reflow soldering |
Pinout & Package
SM15T100AHE3/9AT uses the standard SMC (DO-214AB) package: cathode-marked unidirectional device with two terminals - anode and cathode - in a molded plastic case meeting UL 94 V-0 flammability rating. Matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to system ground or lower-potential node in TVS configuration | Provides low-impedance path to ground during reverse-transient clamping; must be routed with minimal trace inductance |
| Cathode | Current exit terminal in forward bias; marked with band; connected to protected line (e.g., 85 V rail) | Defines polarity-sensitive placement - incorrect orientation prevents clamping and risks catastrophic failure |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use including engine control units and battery management systems requiring zero-failure reliability |
| 1500 W peak pulse power (10/1000 μs) | Withstands IEC 61000-4-5 Level 4 surge (4 kV line-earth) without parametric shift or short-circuit failure |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on protected MOSFETs or gate drivers during fast transients |
| MSL Level 1 moisture sensitivity | Enables direct placement into reflow process without baking, reducing manufacturing overhead and risk of delamination |
| Glass passivated junction | Ensures stable leakage current (<1.0 μA at VWM) and long-term stability under thermal cycling and humidity exposure |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100A-E3/57T | Lower peak pulse power (400 W), same 85.5 V VWM, SMA package (smaller footprint, higher RθJA = 110 °C/W) | Not qualified to AEC-Q101; limited to commercial-grade consumer/industrial use | Select when cost and board space constrain requirements and automotive qualification is not needed |
| SMCJ100AHE3/9AT | Same AEC-Q101 qualification and SMC package, but 1500 W rating achieved with tighter VBR tolerance (95–105 V vs. 95–105 V) and identical clamping (137 V @ 11 A) | Functionally identical clamping behavior and automotive qualification; differs only in internal process optimization | Preferred for new designs requiring full Vishay SMCJ-series documentation traceability and extended lifetime data |
Compared with SMAJ100A-E3/57T and SMCJ100AHE3/9AT, the SM15T100AHE3/9AT delivers identical AEC-Q101 compliance and clamping performance in the same SMC footprint, but with documented 1500 W capability validated under IEC 61000-4-5 test conditions - making it the preferred choice for safety-critical automotive and industrial surge protection where margin and qualification rigor are mandatory.

FAQ
What is the clamping voltage of SM15T100AHE3/9AT at its rated peak pulse current?
The SM15T100AHE3/9AT has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 11.0 A under the standard 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 surge events. The SM15T100AHE3/9AT maintains this clamping performance across its full operating temperature range.
Is SM15T100AHE3/9AT qualified for automotive applications?
Yes, SM15T100AHE3/9AT is explicitly AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's 88380 datasheet. It is rated for operation from -65 °C to +150 °C junction temperature and meets MSL Level 1 reflow requirements - making it suitable for under-hood and body-control module applications. The SM15T100AHE3/9AT carries full traceability and qualification reports per AEC-Q101 Rev G.
What is the standoff voltage (VWM) and why does it matter for SM15T100AHE3/9AT?
The SM15T100AHE3/9AT has a maximum reverse stand-off voltage (VWM) of 85.5 V, meaning it remains non-conductive with leakage <1.0 μA up to this voltage. This parameter ensures reliable operation on 85 V DC rails without false triggering or power loss. Selecting a VWM ≥10 % below the system's maximum steady-state voltage prevents premature conduction while maintaining sufficient margin for transients - a key design rule applied to the SM15T100AHE3/9AT.
How does the SMC (DO-214AB) package of SM15T100AHE3/9AT impact PCB layout?
The SMC package of SM15T100AHE3/9AT requires minimum 8.0 mm × 8.0 mm copper pads per terminal for rated 1500 W performance, as specified in Vishay's thermal derating curves. Its low-inductance structure demands short, wide traces to ground to preserve clamping speed. The SM15T100AHE3/9AT cathode band must align with schematic polarity - reversal causes open-circuit failure during surge events.
What is the peak pulse current rating of SM15T100AHE3/9AT and how is it tested?
The SM15T100AHE3/9AT is rated for 11.0 A peak pulse current (IPPM) under the standardized 10/1000 μs double-exponential waveform per IEC 61000-4-5. This rating is validated using the test setup defined in Figure 3 of Vishay document 88380, with device mounted on 8.0 mm × 8.0 mm copper pads. The SM15T100AHE3/9AT maintains this rating across ambient temperatures up to 125 °C with appropriate derating.
