Product details
Overview
1.5SMC130AHE3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 130 V standoff voltage (VWM), 179 V clamping voltage (VC) at 8.4 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive ECUs, industrial motor drives, and telecom power supplies.
For engineers reviewing the 1.5SMC130AHE3_A/H datasheet, 1.5SMC130AHE3_A/H pinout, 1.5SMC130AHE3_A/H application, or 1.5SMC130AHE3_A/H equivalent, key selection criteria include clamping performance under repetitive surge stress, AEC-Q101 qualification for automotive use, thermal resistance (RθJA = 75 °C/W), and compatibility with automated SMT placement on standard SMC (DO-214AB) footprints.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, activated when reverse voltage exceeds its breakdown threshold (VBR = 124–137 V). Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), critical for protecting MOSFET gates and microcontroller I/O against ESD and lightning-induced transients.
Rated for 150 °C maximum junction temperature and compliant with J-STD-020 MSL level 1 (260 °C peak reflow), the device supports high-reliability deployment in automotive under-hood environments and industrial control systems where thermal cycling and long-term surge endurance are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 124–137 V at 1.0 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 179 V at IPPM = 8.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; directly limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 1500 W - Sustains single 10/1000 μs surges without degradation; enables compliance with IEC 61000-4-5 Level 4 (4 kV) |
| ID (Reverse Leakage) | <1.0 μA at VWM - Negligible standby power loss and minimal signal distortion in high-impedance sensor or data lines. |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient; requires minimum 8.0 mm × 8.0 mm copper pads for full power derating. |
| AEC-Q101 Qualified | Yes - Validated for automotive applications including engine control, ADAS power rails, and infotainment supply protection. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Ground reference for unidirectional clamp | Connected to system ground or low-side return path; carries surge current to ground during clamping. |
| Cathode | Protected line input / High-side connection | Connected to line being protected (e.g., 12 V rail, CAN bus, sensor supply); blocks forward current and clamps reverse transients. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Enables single-event suppression of 4 kV IEC 61000-4-5 surges without failure or parameter shift. |
| Glass passivated chip junction | Ensures stable VBR and low leakage across -65 °C to +150 °C; eliminates risk of moisture-induced parametric drift. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge lifetime testing per AEC standards. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow profiles without popcorn cracking or delamination; no pre-bake required. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ESD >15 kV), improving protection margin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-E3/57T | Lower PPPM (400 W), same VWM (111 V), SOD-123 package (smaller footprint, higher RθJA = 110 °C/W) | Restricted to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 or automotive load dump. | Select only for space-constrained consumer electronics with <500 W surge requirements. |
| 1.5KE130A | Through-hole DO-201 package, identical electrical specs but no AEC-Q101 qualification or MSL 1 rating | Lacks automotive process validation and lead-free reflow compatibility; limited to industrial prototyping or legacy designs. | Choose only for non-automotive, non-SMT applications where board-level reliability certification is not required. |

FAQ
What is the clamping voltage of the 1.5SMC130AHE3_A/H under a 10/1000 μs surge?
The 1.5SMC130AHE3_A/H has a maximum clamping voltage (VC) of 179 V at 8.4 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88303 and defines the upper voltage limit imposed on protected circuits during standardized surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC130AHE3_A/H qualified for automotive applications?
Yes, the 1.5SMC130AHE3_A/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's 1.5SMC series datasheet (Rev. 09-Mar-2026). This qualification covers temperature cycling, high-temperature reverse bias (HTRB), and surge lifetime testing - validating its use in engine control units, ADAS power supplies, and other automotive systems requiring extended reliability.
What package type does the 1.5SMC130AHE3_A/H use, and what are its mounting requirements?
The 1.5SMC130AHE3_A/H uses the SMC (DO-214AB) surface-mount package, with mechanical dimensions specified in inches/mm on page 5 of Vishay document 88303. For full 1500 W power rating, it must be mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, per Figure 2 derating curves - smaller pads reduce surge capability significantly.
How does the 1.5SMC130AHE3_A/H differ from bidirectional variants like 1.5SMC130CA?
The 1.5SMC130AHE3_A/H is unidirectional, with polarity marked by a cathode band and intended for DC line protection where reverse conduction must be blocked. In contrast, 1.5SMC130CA is bidirectional, symmetric in both directions, and used for AC or differential signal lines like RS-485 or CAN bus - the two are not interchangeable without circuit redesign.
What is the maximum junction temperature and thermal resistance of the 1.5SMC130AHE3_A/H?
The 1.5SMC130AHE3_A/H has a maximum junction temperature (TJ max.) of +150 °C and a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted per recommended pad layout. This allows operation in under-hood automotive environments and industrial enclosures up to +105 °C ambient, provided sufficient copper area and airflow are maintained.
