Product details
Overview
5KASMC36AHM3/57 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for high-energy surge clamping with 5000 W peak pulse power (10/1000 μs), 40.0–44.2 V breakdown voltage, and 58.1 V maximum clamping voltage at 86.1 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 5KASMC36AHM3/57 datasheet, 5KASMC36AHM3/57 pinout, 5KASMC36AHM3/57 application, or 5KASMC36AHM3/57 equivalent, key selection criteria include clamping performance under 10/1000 μs transients, thermal stability at TJ = 185 °C, unidirectional polarity compatibility with DC-biased signal lines, and compliance with MSL Level 1 and JESD201 Class 2 whisker resistance.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver stable clamping under repetitive surge stress while maintaining low incremental surge resistance and fast response time (<1 ns). Its 100 °C/W junction-to-ambient thermal resistance is specified for minimum recommended pad layout mounting.
The device is rated for 6.5 W steady-state power dissipation on infinite heatsink at TM = 50 °C and supports operation across -65 °C to +185 °C junction/storage temperature range. It meets UL 94 V-0 flammability requirements and features matte tin-plated leads solderable per J-STD-002 and JESD22-B102.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/57 | Lower PPPM (400 W), smaller SMA package (DO-214AC), VC = 58.1 V at 6.8 A | Suitable for lower-energy transients; not rated for 185 °C or AEC-Q101 | Select when space-constrained and surge energy ≤400 W; verify thermal derating for ambient >125 °C |
| SMCJ36AHE3/57 | Same DO-214AB package, identical VBR/VC, but rated for 150 °C TJ max and no AEC-Q101 | Lacks automotive qualification; lower thermal margin for under-hood use | Acceptable for industrial controls where AEC-Q101 is not mandated; confirm lifecycle support for long-term production |
Compared with SMAJ36A-E3/57 and SMCJ36AHE3/57, the 5KASMC36AHM3/57 delivers higher surge robustness (5000 W vs. 400 W or 1500 W), extended temperature capability (185 °C), and formal AEC-Q101 validation-making it the only choice for safety-critical automotive power domains requiring sustained high-temperature reliability.

FAQ
What is the clamping voltage of the 5KASMC36AHM3/57 under maximum surge conditions?
The 5KASMC36AHM3/57 exhibits a maximum clamping voltage (VC) of 58.1 V when subjected to its rated peak pulse current of 86.1 A using the standard 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The 5KASMC36AHM3/57 maintains this clamping performance across its full operating temperature range due to its passivated junction design.
Is the 5KASMC36AHM3/57 suitable for automotive applications?
Yes, the 5KASMC36AHM3/57 is AEC-Q101 qualified and rated for junction temperatures up to 185 °C, making it suitable for under-hood and powertrain-related automotive applications such as engine control modules, body control units, and ADAS power supplies. Its DO-214AB package, MSL Level 1 rating, and halogen-free HM3 construction further align with automotive manufacturing and reliability requirements. The 5KASMC36AHM3/57 meets these specifications without derating at elevated ambient temperatures.
What does the "HM3/57" suffix indicate in 5KASMC36AHM3/57?
The "HM3" suffix denotes Vishay's halogen-free, RoHS-compliant, AEC-Q101-qualified construction with JESD201 Class 2 whisker resistance, while "/57" specifies the preferred packaging code for 7-inch diameter plastic tape and reel containing 850 units. This ordering format ensures consistent material compliance and automated assembly compatibility. The 5KASMC36AHM3/57 is shipped in this configuration with full traceability documentation.
How does the 5KASMC36AHM3/57 compare to standard SMCJ-series TVS diodes?
The 5KASMC36AHM3/57 provides identical DO-214AB packaging and electrical ratings to legacy SMCJ36A variants but adds AEC-Q101 qualification, 185 °C junction rating, and HM3 material compliance. Unlike generic SMCJ parts, the 5KASMC36AHM3/57 undergoes extended reliability testing for automotive use and guarantees performance stability under thermal cycling and high-humidity conditions. The 5KASMC36AHM3/57 is not a drop-in replacement for non-HM3 SMCJ parts if AEC-Q101 or 185 °C operation is required.
What is the maximum reverse leakage current for the 5KASMC36AHM3/57 at operating temperature?
At VWM = 36 V and TA = 25 °C, the 5KASMC36AHM3/57 exhibits a maximum reverse leakage current (IR) of 2.0 μA. At elevated temperature (TJ = 150 °C), leakage increases to a maximum of 50 μA-still within acceptable limits for most signal-line protection applications. This controlled leakage ensures minimal impact on precision analog circuits while maintaining effective surge response. The 5KASMC36AHM3/57 data sheet specifies both values under defined test conditions.
