Product details
Overview
5KASMC13AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, rated for 5000 W peak pulse power (10/1000 μs), 13 V stand-off voltage (VWM), and 21.5 V maximum clamping voltage (VC) at 300 A peak surge current. It operates up to +185 °C junction temperature and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the 5KASMC13AHM3_A/H datasheet, 5KASMC13AHM3_A/H pinout, 5KASMC13AHM3_A/H application, or 5KASMC13AHM3_A/H equivalent, this page delivers verified electrical specs, thermal derating behavior, SMC package layout compatibility, and direct alternatives for ESD/surge protection in high-reliability sensor signal lines and MOSFET gate circuits.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), enabling effective clamping of inductive switching transients before downstream ICs or power devices are damaged. Its 185 °C maximum junction temperature supports operation in under-hood automotive environments without thermal derating penalties below 150 °C.
The device exhibits a positive temperature coefficient of breakdown voltage (αT = 0.076 %/°C), ensuring stable VBR over temperature, and meets J-STD-020 MSL Level 1 with 260 °C lead-free reflow capability. Cathode identification via molded band and matte tin-plated terminals ensure reliable solderability and polarity-aware PCB assembly.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5A (Vishay) | Lower PPPM (400 W), same VWM (13 V), higher VC (21.5 V → 24.4 V), SMA package (smaller footprint, lower thermal mass) | Not suitable for 5000 W surge events; limited to consumer-grade I/O protection where energy levels are lower. | Select when space-constrained layouts require smaller SMT package and surge energy is ≤400 W (e.g., USB port protection). |
| 1.5KE13A (ON Semiconductor) | Higher VC (24.4 V), through-hole DO-201 package, same VWM (13 V), lower thermal resistance to heatsink but no MSL rating | Requires manual or wave soldering; unsuitable for automated SMT lines or high-reliability automotive reflow profiles. | Choose only for legacy through-hole designs or prototyping where board real estate allows larger package and lead-free reflow is not required. |
Compared with SMAJ13A-E3/5A and 1.5KE13A, the 5KASMC13AHM3_A/H delivers 12.5× higher peak pulse power in an MSL Level 1–qualified SMC package, making it the sole option among the three for AEC-Q101–compliant, high-energy automotive and industrial surge protection.

FAQ
What is the maximum clamping voltage of the 5KASMC13AHM3_A/H at its rated peak pulse current?
The 5KASMC13AHM3_A/H has a maximum clamping voltage (VC) of 21.5 V at 300 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per Figure 1 in the official Vishay datasheet (Document Number: 89432) and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The 5KASMC13AHM3_A/H maintains this clamping performance across its full operating temperature range due to its stable thermal coefficient.
Is the 5KASMC13AHM3_A/H suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the 5KASMC13AHM3_A/H is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet revision dated 19-Jan-2024. It undergoes rigorous stress testing-including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST)-to meet automotive reliability standards. The 5KASMC13AHM3_A/H is therefore approved for use in engine control units, ADAS sensor modules, and body electronics where certified component reliability is mandatory.
What package type does the 5KASMC13AHM3_A/H use, and what are its key mounting features?
The 5KASMC13AHM3_A/H uses the SMC (DO-214AB) surface-mount package, measuring 7.75 mm × 6.22 mm × 2.62 mm. It features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, passes JESD 201 Class 2 whisker testing, and is rated MSL Level 1 with a 260 °C peak reflow profile. The cathode is marked by a visible molded band, and the package is halogen-free and RoHS-compliant-key attributes for the 5KASMC13AHM3_A/H's use in automated SMT lines serving automotive Tier 1 suppliers.
How does the 5KASMC13AHM3_A/H compare to lower-power TVS diodes like SMAJ13A in terms of surge handling capability?
The 5KASMC13AHM3_A/H delivers 5000 W peak pulse power (10/1000 μs), which is 12.5× higher than the 400 W rating of the SMAJ13A-E3/5A. While both share a 13 V stand-off voltage, the 5KASMC13AHM3_A/H sustains its clamping performance at 300 A surge current versus 32.4 A for the SMAJ13A. This makes the 5KASMC13AHM3_A/H uniquely capable of meeting ISO 7637-2 Pulse 5a and IEC 61000-4-5 Level 4 requirements where the SMAJ13A would fail catastrophically.
What is the thermal resistance and maximum junction temperature specification for the 5KASMC13AHM3_A/H?
The 5KASMC13AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended pad layout, and a maximum junction temperature (TJ) of +185 °C. Its junction-to-mount thermal resistance (RθJM) is 20.8 °C/W, indicating efficient heat transfer to the PCB copper. These values enable the 5KASMC13AHM3_A/H to operate continuously at full power in high-ambient environments such as automotive engine compartments without external heatsinking.
