Product details
Overview
1.5SMC13AHM3/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 13 V breakdown voltage (VBR = 12.4–13.7 V at 1.0 mA), 11.1 V stand-off voltage (VWM), and clamps transients to ≤18.2 V at 82.4 A peak pulse current (10/1000 µs), delivering 1500 W peak pulse power. It is used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the 1.5SMC13AHM3/H datasheet, 1.5SMC13AHM3/H pinout, 1.5SMC13AHM3/H application, or 1.5SMC13AHM3/H equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant HM3 suffix, SMC (DO-214AB) surface-mount package, and verified clamping performance under repetitive surge conditions.
Technical Context
This unidirectional TVS diode operates with a glass-passivated junction and exhibits fast response time (<1 ns), low incremental surge resistance, and excellent clamping ratio (VC/VBR ≈ 1.42). Its thermal resistance is RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation up to TJ = 150 °C.
The device meets MSL level 1 per J-STD-020 (peak reflow temperature 260 °C), supports 200 A non-repetitive forward surge (8.3 ms half-sine), and maintains <1000 µA reverse leakage at VWM, ensuring minimal standby power loss in protected circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V at 1.0 mA - defines precise avalanche initiation threshold for predictable clamping onset |
| VWM | 11.1 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | ≤18.2 V at 82.4 A (10/1000 µs) - ensures downstream components see safe voltage during surge events |
| PPPM | 1500 W - peak transient power handling capability under standardized lightning/surge waveform |
| IFSM | 200 A (8.3 ms half-sine) - withstands high-energy inrush or fault currents without failure |
| TJ max. | +150 °C - enables use in under-hood automotive and high-temperature industrial environments |

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 | Lower peak power rating (600 W), same VBR range, SMB package (smaller footprint, higher RθJA) | Not suitable for IEC 61000-4-5 Level 4; limited to lower-energy transients | Select only if space-constrained and surge energy is ≤600 W |
| 1.5KE13A | Through-hole DO-201 package, identical electrical specs but no AEC-Q101 or halogen-free certification | Excludes automotive and high-reliability industrial use; requires wave soldering | Choose for legacy through-hole designs where rework flexibility outweighs surface-mount advantages |
Compared with SMBJ13A and 1.5KE13A, the 1.5SMC13AHM3/H uniquely combines AEC-Q101 qualification, halogen-free compliance, 1500 W surge capacity, and SMC surface-mount compatibility-making it the only option qualified for next-generation automotive power modules requiring zero rework risk and full environmental compliance.

FAQ
What is the breakdown voltage tolerance for 1.5SMC13AHM3/H?
The 1.5SMC13AHM3/H has a specified breakdown voltage range of 12.4 V to 13.7 V at 1.0 mA test current, representing ±5.4% tolerance around the nominal 13 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports reliable design margining in safety-critical circuits.
Is 1.5SMC13AHM3/H suitable for bidirectional surge protection?
No, the 1.5SMC13AHM3/H is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the 1.5SMC13CA variant. Using 1.5SMC13AHM3/H in AC or floating applications risks forward conduction during negative transients, potentially causing failure or incorrect clamping.
Does 1.5SMC13AHM3/H meet automotive qualification standards?
Yes, the HM3 suffix confirms that 1.5SMC13AHM3/H is AEC-Q101 qualified and halogen-free. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and surge endurance per the AEC-Q101 standard-making it approved for use in engine control units, body electronics, and ADAS power domains.
What is the maximum clamping voltage of 1.5SMC13AHM3/H under surge conditions?
The 1.5SMC13AHM3/H clamps to a maximum of 18.2 V when subjected to its rated 82.4 A peak pulse current (10/1000 µs waveform). This value is guaranteed across temperature and lifetime, and represents the highest voltage seen by protected circuitry during worst-case surge events.
How does the SMC package of 1.5SMC13AHM3/H compare thermally to SMA or SMB packages?
The SMC (DO-214AB) package of 1.5SMC13AHM3/H provides lower thermal resistance than SMA (DO-214AC) or SMB (DO-214AA): RθJA = 75 °C/W vs. ~100–120 °C/W for smaller variants. Its larger copper pad area (8.0 mm × 8.0 mm) enables superior heat dissipation during repetitive surges, extending device lifetime in high-duty-cycle applications.
