Product details
Overview
5KASMC36AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, rated for 36 V stand-off voltage (VWM), 42.1 V nominal breakdown (VBR), 5000 W peak pulse power (10/1000 μs), 86.1 V clamping voltage at 50 A surge current, and qualified to AEC-Q101 for automotive electronics protection.
For engineers reviewing the 5KASMC36AHM3_A/I datasheet, 5KASMC36AHM3_A/I pinout, 5KASMC36AHM3_A/I application, or 5KASMC36AHM3_A/I equivalent, this page delivers verified electrical parameters, thermal performance at TJ = 185 °C, SMC package mechanical data, and AEC-Q101-compliant reliability metrics for high-temperature ESD/surge protection design.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for junction stability up to 185 °C, enabling operation in under-hood automotive environments and industrial control systems where thermal derating must be minimized. Its unidirectional polarity and low incremental surge resistance ensure fast clamping response during inductive load switching transients.
The device meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility, features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and passes JESD 201 Class 2 whisker testing - all confirmed for the HM3 suffix variant.
Key Specifications

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 3a/b (load dump). IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp transients before they reach downstream regulators and microcontrollers. Use Value: 5000 W PPPM and 86.1 V VC at 50 A ensure compliance with OEM surge immunity requirements while maintaining safe margin below IC absolute maximum ratings. | Use Scenario: Safeguarding analog outputs of pressure/temperature sensors in PLC I/O modules exposed to field wiring surges. IC Role / Device Role / Timing Role: Low-leakage (2.0 μA) TVS connected across sensor output and ground to suppress EFT bursts without loading the signal path. Use Value: 42.1 V VBR and 36 V VWM allow integration into 24 V industrial control loops with minimal standby current impact and no false triggering. |
| Telecom DC Power Input Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Shielding PoE-powered network switches from induced surges on 48 V DC input derived from external adapters. IC Role / Device Role / Timing Role: Primary-level TVS on DC input rail upstream of DC/DC converters to prevent catastrophic failure during lightning-induced surges. Use Value: 185 °C TJ max and 100 °C/W RθJA enable reliable operation in sealed enclosures with limited airflow and ambient temperatures up to 85 °C. | Use Scenario: Suppressing back-EMF spikes generated by brushed DC motors in smart home appliances (e.g., vacuum cleaners, washing machines). IC Role / Device Role / Timing Role: Fast-response TVS mounted across motor terminals to divert inductive kickback energy away from driver MOSFETs and MCU GPIOs. Use Value: Sub-100 ns response time and 0.5 Ω incremental surge resistance limit voltage overshoot to < 90 V, preventing gate oxide rupture in 100 V-rated FETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/5A (Vishay) | Lower PPPM (400 W), SMA package (smaller thermal mass), same VWM/VBR range | Not suitable for automotive load-dump; limited to low-energy ESD and EFT events | Select only for space-constrained consumer designs where 5000 W surge capability is unnecessary |
| 1.5KE36A (ON Semiconductor) | Through-hole DO-201 package, higher RθJA (~60 °C/W), same 36 V VWM but lower VBR tolerance (±10 % vs. ±5 %) | Requires PCB through-holes and manual assembly; unsuitable for automated SMT production | Choose only for legacy board redesigns retaining through-hole infrastructure and lower cost sensitivity |
Compared with SMAJ36A-E3/5A and 1.5KE36A, the 5KASMC36AHM3_A/I delivers 12.5× higher surge power handling in an AEC-Q101-qualified SMT package, enabling single-device compliance with ISO 16750-2 load-dump tests without parallel devices or heatsinking.

FAQ
What is the clamping voltage of the 5KASMC36AHM3_A/I at its rated peak pulse current?
The 5KASMC36AHM3_A/I has a maximum clamping voltage (VC) of 86.1 V when subjected to a 50 A peak pulse current with a 10/1000 μs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuits during surge events. The 5KASMC36AHM3_A/I maintains this clamping performance across its full operating temperature range, supporting robust design margins in automotive and industrial applications.
Is the 5KASMC36AHM3_A/I suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the 5KASMC36AHM3_A/I is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 19-Jan-2024 (Document Number: 89432). It undergoes stress testing including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling to meet automotive reliability standards. The 5KASMC36AHM3_A/I is designed for under-hood and body-control module use where junction temperatures may reach +185 °C.
What does the "HM3_A/I" suffix indicate in the 5KASMC36AHM3_A/I part number?
The "HM3" suffix denotes Vishay's halogen-free, RoHS-compliant, and AEC-Q101-qualified molding compound; "A" is the revision code; and "I" specifies packaging in 13-inch diameter plastic tape and reel with a base quantity of 3500 units. The 5KASMC36AHM3_A/I is distinct from the "H" variant (7-inch reel, 850 units), and both share identical electrical and thermal specifications per the datasheet.
How does the thermal resistance of the 5KASMC36AHM3_A/I affect its power dissipation capability?
The 5KASMC36AHM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended pad layout. At 25 °C ambient, this limits continuous power dissipation to 6.5 W - consistent with its rated PD. Derating follows the published curve: above 25 °C, allowable power decreases linearly to zero at 150 °C ambient. The 5KASMC36AHM3_A/I's RθJM of 20.8 °C/W supports higher transient power handling when mounted on thermally enhanced PCBs.
Can the 5KASMC36AHM3_A/I replace older TVS diodes like P6KE36A in new designs?
The 5KASMC36AHM3_A/I offers superior performance versus P6KE36A: it provides 5000 W vs. 600 W peak pulse power, SMC surface-mount vs. DO-15 through-hole packaging, AEC-Q101 qualification vs. no automotive rating, and 185 °C vs. 175 °C max junction temperature. However, it is not a direct drop-in replacement due to different package dimensions and thermal paths. Redesign of PCB layout and thermal validation are required when migrating to the 5KASMC36AHM3_A/I from P6KE36A.
