Product details
Overview
1.5SMC13AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection. It features 13 V breakdown voltage (VBR min/max = 12.4–13.7 V at 1.0 mA), 11.1 V stand-off voltage (VWM), 18.2 V clamping voltage (VC) at 82.4 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 μs waveform - used to safeguard MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the 1.5SMC13AHM3/I datasheet, 1.5SMC13AHM3/I pinout, 1.5SMC13AHM3/I application, or 1.5SMC13AHM3/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), polarity marking (cathode band), and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker test.
Technical Context
The 1.5SMC13AHM3/I operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology for stable reverse breakdown behavior and fast response (<1 ps). Its clamping action limits transient overvoltage to ≤18.2 V during 10/1000 μs surges up to 82.4 A, while maintaining low incremental surge resistance and excellent energy absorption capability.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads, it supports automated placement and meets MSL Level 1 (reflow peak 260 °C). The device is halogen-free, RoHS-compliant, and qualified to AEC-Q101 for automotive-grade reliability - confirmed by suffix "HM3" and revision code "I" indicating halogen-free, AEC-Q101-compliant commercial grade with 13" tape-and-reel packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at IT = 1.0 mA - defines precise avalanche onset threshold for reliable overvoltage triggering |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 5.0 μA |
| VC @ IPPM | 18.2 V at 82.4 A - clamped voltage during full 1500 W surge, ensuring downstream ICs stay below safe stress limits |
| PPPM | 1500 W - peak pulse power handling with 10/1000 μs waveform, enabling robust lightning and inductive-switching protection |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance under standard PCB pad layout, critical for thermal derating above 25 °C |
| TJ max | +150 °C - maximum junction temperature, supporting operation in under-hood automotive and industrial environments |
| IFSM | 200 A - non-repetitive forward surge current (8.3 ms half-sine), relevant for DC bus fault protection |

Applications
| Automotive Power Supply Protection | Industrial Sensor Signal Line Guarding |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and ground to clamp surges before they reach PMICs and microcontrollers. Use Value: Clamps to 18.2 V at 82.4 A, keeping downstream 3.3 V/5 V regulators within safe input range during ISO 7637-2 Pulse 5a events. |

IC Role / Device Role / Timing Role: Low-capacitance TVS on 4–20 mA or 0–10 V signal paths to suppress ESD and field-induced spikes. Use Value: Sub-1 ns response ensures transient suppression occurs before sensor amplifier input stages saturate or latch up. |
| Consumer Device DC Adapter Input | Telecom Equipment Power Interface |
Use Scenario: Safeguarding USB-C PD and AC/DC adapter inputs against accidental AC line surges and hot-plug transients. IC Role / Device Role / Timing Role: Primary-level TVS on input rectifier output to absorb energy before it reaches primary-side controllers. Use Value: 1500 W rating handles repetitive 10/1000 μs surges common in shared building power infrastructure. |
Use Scenario: Front-end protection of PoE-powered switches and base station power interfaces exposed to lightning-induced surges. IC Role / Device Role / Timing Role: First-stage unidirectional suppressor on 48 V DC input rails prior to DC-DC converters. Use Value: 11.1 V VWM allows compatibility with 12 V control logic while clamping 48 V surges to safe levels via cascaded protection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Same VBR range (12.4–13.7 V), but SMB package (smaller footprint, lower PPPM = 600 W) | Limited to lower-energy transients; unsuitable for automotive load dump or industrial lightning protection | Select when board space is constrained and surge threat level is ≤600 W (e.g., consumer USB ports) |
| 1.5KE13A | Through-hole TO-204AA (DO-41), identical electrical specs but higher RθJA (~100 °C/W) and no AEC-Q101 qualification | Not suitable for automated SMT production or automotive qualification programs | Choose only for legacy through-hole designs where rework tolerance and manual assembly are acceptable |
Compared with SMBJ13A and 1.5KE13A, the 1.5SMC13AHM3/I uniquely combines 1500 W surge capacity, SMC surface-mount form factor, AEC-Q101 qualification, and halogen-free compliance - making it the only option among the three validated for high-reliability automotive and industrial SMT production.

FAQ
What is the clamping voltage of the 1.5SMC13AHM3/I and how is it measured?
The 1.5SMC13AHM3/I has a maximum clamping voltage (VC) of 18.2 V, measured at its peak pulse current (IPPM) of 82.4 A using a standardized 10/1000 μs double-exponential surge waveform. This value reflects the actual voltage seen by protected circuitry during worst-case transient events and is guaranteed per Vishay's datasheet test conditions on specified PCB pad layout.
Is the 1.5SMC13AHM3/I qualified for automotive applications?
Yes, the 1.5SMC13AHM3/I is AEC-Q101 qualified, as confirmed by its "HM3" suffix and revision code "I", indicating halogen-free, RoHS-compliant construction with full automotive reliability testing. It is approved for use in engine control modules, body electronics, and ADAS power domains where transient immunity and long-term stability are mandatory.
What does the "HM3/I" suffix mean in 1.5SMC13AHM3/I?
The "HM3" denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction; "I" specifies the packaging variant - 13" diameter plastic tape-and-reel with 3500 units per reel. This suffix directly maps to Vishay's ordering nomenclature in Document 88303 and confirms compliance with JESD201 Class 2 whisker resistance and MSL Level 1 reflow requirements.
How does the 1.5SMC13AHM3/I differ from the standard 1.5SMC13A?
The 1.5SMC13AHM3/I is a qualified variant of the base 1.5SMC13A, adding halogen-free materials, AEC-Q101 qualification, and JESD201 Class 2 whisker resistance - while retaining identical electrical characteristics (VBR, VWM, VC, PPPM). The "HM3/I" version is intended for automotive and high-reliability industrial use, whereas the base "A" suffix lacks formal qualification and environmental certifications.
What is the thermal resistance of the 1.5SMC13AHM3/I and why does it matter?
The 1.5SMC13AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads. This value determines how much the junction temperature rises under steady-state power dissipation (e.g., 6.5 W) and is essential for derating peak pulse power at elevated ambient temperatures - especially critical in enclosed automotive or industrial enclosures.
