Product details
Overview
1.5SMC130AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 130 V standoff voltage (VWM), 179 V clamping voltage at 8.4 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform. Used to protect MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching spikes in automotive and industrial power supplies.
For engineers reviewing the 1.5SMC130AHE3/57T datasheet, 1.5SMC130AHE3/57T pinout, 1.5SMC130AHE3/57T application, or 1.5SMC130AHE3/57T equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, SMC (DO-214AB) package dimensions, thermal resistance data, and real-world protection use cases - all confirmed from Vishay's official 1.5SMC Series specification document (Rev. 09-Mar-2026, Doc. #88303).
Technical Context
This TVS diode operates as a unidirectional clamping device with a cathode-band polarity marking, optimized for fast response (<1 ns) to transient overvoltages. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, critical for consistent clamping under repetitive 10/1000 μs surges at 0.01% duty cycle.
Thermally, it exhibits RθJA = 75 °C/W (on standard 8.0 mm × 8.0 mm copper pads) and RθJL = 15 °C/W, enabling reliable operation up to TJ = 150 °C. The device is RoHS-compliant and AEC-Q101 qualified (via HE3 suffix), confirming suitability for automotive-grade power rail and sensor line protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 111 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC working margin. |
| VBR (Breakdown, min/max) | 124 V / 137 V at IT = 1 mA - Tight 13 V window ensures predictable turn-on threshold across production lots. |
| VC (Clamping, at IPPM) | 179 V at 8.4 A - Limits downstream voltage stress during 10/1000 μs transients, protecting 150 V-rated components. |
| PPPM | 1500 W - Sustains high-energy surges typical of ISO 7637-2 Pulse 1/2b and IEC 61000-4-5 Level 4 events. |
| IPPM | 8.4 A - Peak pulse current rating derived from 10/1000 μs waveform; determines minimum trace width and PCB layout robustness. |
| TJ max. | +150 °C - Enables deployment in under-hood automotive environments and industrial power converters without derating. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height; compatible with automated pick-and-place. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, MSL level 1 (260 °C reflow peak). Cathode indicated by band on body; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VLINE exceeds VBR. |
| Anode (unbanded end) | Reference node | Typically tied to system ground or low-impedance return path; completes clamping loop during overvoltage event. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Withstands automotive load-dump and lightning-simulated surges without degradation, per ISO 7637-2 and IEC 61000-4-5. |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V supply inputs in engine control modules against load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between battery rail and DC-DC converter input. Use Value: Clamps transients to ≤179 V, preventing damage to downstream 150 V-rated MOSFETs and LDO regulators. |
Use Scenario: Safeguarding analog output lines of pressure/temperature sensors in factory automation PLCs. IC Role / Device Role / Timing Role: Line-side transient suppressor on 4–20 mA current loop outputs exposed to ESD and cable discharge events. Use Value: Responds in <1 ns to sub-microsecond ESD pulses, limiting induced voltage to <200 V at sensor amplifier inputs. |
| Telecom DC Power Feeds | Consumer Power Adapter Outputs |

IC Role / Device Role / Timing Role: Primary overvoltage clamp on rectified -48 V bus feeding PoE injectors and line cards. Use Value: Absorbs 1500 W peak energy without failure, maintaining system uptime during Category C2/C3 surge events. |
Use Scenario: Secondary-side protection on 12 V/19 V outputs of laptop AC adapters against user-induced plug/unplug transients. IC Role / Device Role / Timing Role: Final-stage TVS on adapter output connector to prevent backfeed damage to connected devices. Use Value: Low leakage (<1 μA at 111 V) avoids standby power loss while delivering certified 1500 W surge immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A-E3/52 | Lower peak power (600 W), SMB package (smaller footprint, higher RθJA = 90 °C/W) | Not suitable for 1500 W surge events; limited to consumer-grade or low-energy industrial signals. | Select only if space-constrained and surge threat level is ≤600 W (e.g., USB or I²C lines). |
| 1.5KE130A | Through-hole DO-201 package, identical VWM/VC specs but lower mounting reliability and no AEC-Q101 qualification. | Requires manual soldering or wave soldering; not approved for automotive under-hood use. | Choose only for legacy through-hole designs where rework to SMD is impractical. |
Compared with SMBJ130A-E3/52 and 1.5KE130A, the 1.5SMC130AHE3/57T uniquely combines AEC-Q101 qualification, 1500 W surge capacity, and SMC surface-mount compatibility - making it the only option among the three validated for automotive power rail protection with zero layout compromise.

FAQ
What is the clamping voltage of the 1.5SMC130AHE3/57T and how is it measured?
The 1.5SMC130AHE3/57T has a maximum clamping voltage (VC) of 179 V, measured at a peak pulse current (IPPM) of 8.4 A using a standardized 10/1000 μs double-exponential waveform. This value is guaranteed across temperature and production lots per Vishay's 1.5SMC Series specification (Doc. #88303, Rev. 09-Mar-2026), and reflects the actual voltage seen by downstream components during worst-case surge events.
Is the 1.5SMC130AHE3/57T AEC-Q101 qualified?
Yes, the 1.5SMC130AHE3/57T is AEC-Q101 qualified, as confirmed by its "HE3" suffix and explicit listing in Vishay's ordering table (page 3, Doc. #88303). This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD, validating its use in automotive powertrain and chassis applications.
What is the standoff voltage (VWM) of the 1.5SMC130AHE3/57T and why does it matter?
The 1.5SMC130AHE3/57T has a VWM of 111 V - the maximum continuous reverse voltage it can withstand without significant leakage. This parameter ensures reliable operation on 100 V nominal systems (e.g., 24 V automotive with 4× load dump margin) while avoiding false triggering during normal operation, directly impacting system uptime and protection integrity.
Does the 1.5SMC130AHE3/57T have a bidirectional variant?
No - the 1.5SMC130AHE3/57T is unidirectional only, indicated by the "A" suffix. Bidirectional variants use the "CA" suffix (e.g., 1.5SMC130CA). The unidirectional configuration provides lower capacitance and tighter VBR tolerance, making it preferred for DC power rail protection where polarity is fixed and leakage must be minimized.
What is the thermal resistance of the 1.5SMC130AHE3/57T and how does it affect layout?
The 1.5SMC130AHE3/57T has RθJA = 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. This value dictates minimum copper area required to maintain TJ ≤ 150 °C under sustained 6.5 W power dissipation. Layouts must replicate this pad size or add thermal vias to avoid thermal runaway during repetitive surge events.
