Product details
Overview
5KASMC10AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for high-reliability overvoltage protection in automotive and industrial systems. It delivers 5000 W peak pulse power (10/1000 μs), clamps at 17.0 V max under 294.1 A surge, and operates up to TJ = 185 °C with AEC-Q101 qualification - deployed on signal lines of automotive sensor units and MOSFET gate drivers.
For engineers reviewing the 5KASMC10AHM3_A/H datasheet, 5KASMC10AHM3_A/H pinout, 5KASMC10AHM3_A/H application, or 5KASMC10AHM3_A/H equivalent, key selection criteria include its 10 V stand-off voltage, 11.1–12.3 V breakdown range at 1 mA, low incremental surge resistance, MSL Level 1 rating, and SMC (DO-214AB) package compatibility with JESD 22-B102 soldering standards.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for junction stability under repetitive surge stress. Its unidirectional polarity enables asymmetric clamping in DC-biased circuits, and the 100 °C/W junction-to-ambient thermal resistance requires careful PCB pad layout per Vishay's recommended footprint.
The device meets AEC-Q101 stress test requirements for automotive use and supports operation from –65 °C to +185 °C. Its 0.069 %/°C temperature coefficient of VBR ensures predictable breakdown drift across temperature, critical for precision protection in engine control modules and ADAS sensor interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Lower PPPM (600 W), same VWM (10 V), SMC-compatible but SMB package (smaller thermal mass) | Limited to lower-energy transients; unsuitable for automotive load dump or industrial motor drive spikes | Select only for space-constrained consumer electronics where 5000 W surge immunity is not required |
| 5.0SMDJ10A | Same 5000 W rating and 10 V VWM, but DO-214AB package with higher RθJA (120 °C/W vs. 100 °C/W) | Requires larger copper area for thermal management; less robust under sustained high-TA conditions | Preferable only if legacy board design already uses 5.0SMDJ footprint and thermal margin allows |
Compared with SMBJ10A and 5.0SMDJ10A, the 5KASMC10AHM3_A/H offers superior thermal performance (100 °C/W RθJA) and AEC-Q101 qualification out-of-box, making it the preferred choice for automotive and high-reliability industrial deployments where junction temperature stability and surge repeatability are critical.

FAQ
What is the maximum clamping voltage of the 5KASMC10AHM3_A/H under full-rated surge current?
The 5KASMC10AHM3_A/H has a maximum clamping voltage (VC) of 17.0 V when subjected to its peak pulse current (IPPM) of 294.1 A under a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 89432 and ensures downstream ICs remain within safe operating voltage limits during standardized surge events such as ISO 7637-2 Pulse 5a.
Is the 5KASMC10AHM3_A/H compatible with lead-free reflow soldering processes?
Yes, the 5KASMC10AHM3_A/H is rated for MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, and the HM3 suffix confirms qualification to JESD 201 Class 2 whisker testing - making it fully compatible with standard lead-free SMT assembly lines.
Does the 5KASMC10AHM3_A/H meet automotive qualification standards?
Yes, the 5KASMC10AHM3_A/H is AEC-Q101 qualified, as explicitly stated in Vishay document 89432. This certification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), temperature cycling, and mechanical shock - validating its suitability for under-hood automotive applications such as engine control units and ADAS sensor modules.
What is the thermal resistance from junction to ambient for the 5KASMC10AHM3_A/H?
The typical thermal resistance from junction to ambient (RθJA) for the 5KASMC10AHM3_A/H is 100 °C/W when mounted on the minimum recommended pad layout. This value assumes standard FR-4 PCB with specified copper area per Vishay's mounting pad layout drawing - critical for calculating safe power dissipation in continuous or repetitive surge scenarios.
How does the temperature coefficient affect the breakdown voltage of the 5KASMC10AHM3_A/H?
The 5KASMC10AHM3_A/H has a typical temperature coefficient of VBR (αT) of +0.069 %/°C. Using the formula VBR at TJ = VBR at 25 °C × (1 + αT × (TJ − 25)), its breakdown voltage increases predictably with junction temperature - e.g., rising from 11.7 V at 25 °C to ~12.5 V at 150 °C - ensuring stable clamping behavior across its full –65 °C to +185 °C operating range.
