Product details
Overview
1.5SMC130A-M3/9AT 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 breakdown voltage (VBR min/max: 124 V / 137 V), 111 V stand-off voltage (VWM), 179 V clamping voltage (VC) at 8.4 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive power supplies, industrial motor controllers, and telecom interface protection.
For engineers reviewing the 1.5SMC130A-M3/9AT datasheet, 1.5SMC130A-M3/9AT pinout, 1.5SMC130A-M3/9AT application, or 1.5SMC130A-M3/9AT equivalent, key selection criteria include unidirectional polarity, SMC (DO-214AB) package compatibility, clamping performance under IEC 61000-4-5 surge conditions, thermal resistance (RθJA = 75 °C/W), and halogen-free RoHS compliance per M3 suffix.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM (111 V), it avalanches rapidly to limit transient overvoltage across protected circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM).
Designed for repetitive surge handling up to 0.01% duty cycle, it delivers 1500 W peak pulse power with <1 ns response time and low incremental surge resistance - enabling robust protection of MOSFET gates, DC-DC converter inputs, and CAN/LIN bus transceivers against lightning-induced and inductive-switching transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 124 V / 137 V at 1.0 mA test current - defines precise avalanche initiation range for reliable triggering |
| VWM | 111 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 179 V at 8.4 A - clamping voltage during full 1500 W surge, limiting stress on downstream ICs |
| PPPM | 1500 W (10/1000 μs waveform) - peak surge energy absorption capability per IEC 61000-4-5 |
| IPPM | 8.4 A - peak pulse current corresponding to rated clamping voltage and power |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, critical for derating above 25 °C |
| TJ max | +150 °C - maximum junction temperature, supporting operation in under-hood automotive environments |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads. Cathode indicated by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side in unidirectional configuration; carries forward surge current (IFSM = 200 A) |

Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Enables single-device protection against Level 4 IEC 61000-4-5 surges (4 kV/2 Ω) on 12 V/24 V rails |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes voltage overshoot during transients, reducing risk of latch-up or gate oxide damage in protected MOSFETs |
| MSL Level 1 (260 °C reflow) | Supports standard lead-free PCB assembly without moisture sensitivity concerns or baking requirements |
| Halogen-free & RoHS-compliant (M3 suffix) | Fulfills environmental compliance for automotive and industrial OEMs requiring IEC 61249-2-21 and JEDEC J-STD-020 |
| Fast response time (<1 ns) | Clamps transients before sensitive logic or analog circuitry responds, preventing data corruption or reset events |
Applications
| Automotive Power Supply Protection | Industrial Motor Drive Interface |

Use Scenario: Securing AC-DC adapter outputs in smart home hubs and HVAC controllers against capacitor discharge and relay bounce. IC Role / Device Role / Timing Role: Final-stage transient suppressor on regulated 5 V/3.3 V rails feeding microcontrollers and sensors. Use Value: Low leakage (<1 μA) avoids standby current penalties; SMC package enables automated placement and high board density. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A-E3/52T | Lower PPPM (600 W), SMB package (smaller footprint, higher RθJA = 85 °C/W) | Suitable for space-constrained consumer electronics where 1500 W margin is not required | Select when board area is limited and surge threat level is ≤ Level 3 (IEC 61000-4-5) |
| 1.5KE130A-T | Through-hole DO-201 package, same VBR/VC, but slower thermal response and no MSL-1 rating | Used in legacy industrial power supplies where manual assembly or wave soldering remains standard | Choose only if SMT process is unavailable or mechanical robustness under vibration is prioritized over thermal performance |
Compared with SMBJ130A-E3/52T and 1.5KE130A-T, the 1.5SMC130A-M3/9AT provides superior surge handling in a surface-mount format with automotive-grade thermal and environmental compliance - making it optimal for new designs targeting AEC-Q101 alignment and high-reliability SMT production.

FAQ
What is the clamping voltage of the 1.5SMC130A-M3/9AT under full-rated surge current?
The 1.5SMC130A-M3/9AT has a maximum clamping voltage (VC) of 179 V at its rated peak pulse current (IPPM) of 8.4 A, measured with a 10/1000 μs waveform. This value ensures downstream components see limited overvoltage during standardized surge events, and is confirmed in the Vishay 88303 datasheet Table "ELECTRICAL CHARACTERISTICS" for part number 1.5SMC130A.
Is the 1.5SMC130A-M3/9AT suitable for automotive applications?
Yes - the 1.5SMC130A-M3/9AT is halogen-free and RoHS-compliant (M3 suffix), and belongs to the AEC-Q101-qualified 1.5SMC family (per datasheet note: "_A is available for 1.5SMC6.8(C)A to 1.5SMC220(C)A, AEC-Q101 qualified"). Its 150 °C max junction temperature, MSL Level 1 rating, and robust surge performance make it appropriate for under-hood and body electronics use cases.
What does the "/9AT" suffix indicate in 1.5SMC130A-M3/9AT?
The "/9AT" suffix denotes packaging: 13-inch diameter plastic tape and reel, with a standard quantity of 3500 pieces per reel. This is confirmed in the "ORDERING INFORMATION" table of the Vishay 88303 datasheet, where /9AT is explicitly listed alongside base part numbers including 1.5SMC130A-M3.
How does the 1.5SMC130A-M3/9AT differ from bidirectional variants like 1.5SMC130CA?
The 1.5SMC130A-M3/9AT is unidirectional (cathode-banded), intended for DC line protection where polarity is fixed; 1.5SMC130CA is bidirectional and symmetrical, used for AC or differential signal lines. Electrical specs differ: VBR for 1.5SMC130CA is 124–137 V in both directions, while 1.5SMC130A-M3/9AT specifies VBR only in reverse - forward conduction is defined by VF = 3.5 V at 100 A.
What is the thermal resistance of the 1.5SMC130A-M3/9AT, and how does it affect layout?
The 1.5SMC130A-M3/9AT has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. To maintain reliability under repeated surges, PCB layout must provide adequate copper area and avoid thermal bottlenecks - insufficient copper increases junction temperature and reduces surge endurance.
