Product details
Overview
5KASMC30AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in automotive and industrial power rails. It delivers 5000 W peak pulse power (10/1000 μs), clamps at ≤48.4 V under 103.3 A surge current, and operates up to +185 °C junction temperature - enabling robust protection of MOSFETs and ICs against inductive switching transients.
For engineers reviewing the 5KASMC30AHM3_A/H datasheet, 5KASMC30AHM3_A/H pinout, 5KASMC30AHM3_A/H application, or 5KASMC30AHM3_A/H equivalent, this page provides verified electrical specs, SMC (DO-214AB) package details, AEC-Q101 qualification status, thermal resistance data, and real-world use cases in automotive sensor signal lines and DC bus protection.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable clamping performance across -65 °C to +185 °C operating range. Its 100 °C/W junction-to-ambient thermal resistance (RθJA) and 20.8 °C/W junction-to-mount (RθJM) support reliable operation on standard PCB pads without heatsinking.
It meets J-STD-020 MSL Level 1 with 260 °C reflow peak, features matte tin-plated leads compliant with JESD 22-B102, and passes JESD 201 Class 2 whisker testing. The cathode band denotes polarity, and the device is halogen-free, RoHS-compliant, and AEC-Q101 qualified.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 5000 W - sustains high-energy surges common in automotive load-dump and inductive switch-off events |
| Clamping Voltage (VC @ IPPM) | 48.4 V max at 103.3 A - limits voltage seen by downstream MOSFETs or controllers during transient events |
| Standoff Voltage (VWM) | 30 V - ensures no conduction during normal 24 V system operation, minimizing leakage risk |
| Breakdown Voltage (VBR) | 33.3–36.8 V @ 1 mA - defines precise turn-on threshold for predictable clamping onset |
| Junction Temperature Range | -65 °C to +185 °C - supports under-hood automotive placement and high-reliability industrial environments |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 7.75 mm × 6.22 mm footprint and 2.62 mm height |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
Pinout & Package
Package: SMC (DO-214AB), molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated terminals; cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode | Current exit terminal during clamping; marked with band | Connected to system ground or low-impedance return path; defines unidirectional conduction direction |
Key Features
| Feature | Design Value |
|---|---|
| 185 °C Junction Capability | Enables direct mounting near hot components (e.g., power converters) without derating penalties |
| Low Incremental Surge Resistance | Minimizes VC overshoot during fast-rising transients (<1 ns response time implied by design) |
| MSL Level 1 Moisture Sensitivity | Allows standard SMT reflow without baking, reducing manufacturing overhead and handling risk |
| Halogen-Free & RoHS-Compliant | Meets global environmental compliance requirements for automotive and industrial OEM supply chains |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: Protecting 24 V CAN node power rails from load-dump transients during battery disconnect/reconnect. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between fused 24 V input and local regulator input. Use Value: Limits voltage to ≤48.4 V during 5000 W surges, preventing damage to LDOs and CAN transceivers rated for 40 V absolute max. |
Use Scenario: Shielding 24 V digital input channels from field-wiring induced surges in factory automation cabinets. IC Role / Device Role / Timing Role: Primary overvoltage clamp on dry-contact input lines before optocoupler or Schmitt-trigger input stage. Use Value: Withstands repeated 10/1000 μs surges up to 103.3 A while maintaining <2 μA leakage at 30 V, preserving input logic integrity. |
| Automotive Sensor Signal Line Protection | DC Motor Drive Power Rail Clamp |
Use Scenario: Safeguarding analog output lines (e.g., 0–5 V throttle position sensor) from coupled transients in adjacent harness bundles. IC Role / Device Role / Timing Role: Low-capacitance TVS placed at connector interface to suppress EFT and ISO 7637-2 pulses. Use Value: Clamps sub-100 ns spikes without distorting signal fidelity due to optimized junction passivation and low dynamic impedance. |
Use Scenario: Suppressing inductive kickback from brushed DC motor commutation in automotive seat/mirror actuators. IC Role / Device Role / Timing Role: Parallel-mounted TVS across motor terminals to absorb energy during PWM turn-off transitions. Use Value: Dissipates 5000 W peak energy without thermal runaway, leveraging 185 °C TJ rating for sustained duty-cycle operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A (onsemi) | Same 30 V VWM, but lower 600 W PPPM rating and 150 °C max TJ; SMC package not identical - SMB is smaller (DO-214AA) | Limited to lower-energy transients; unsuitable for full load-dump compliance per ISO 16750-2 | Select only for cost-sensitive non-automotive applications where 5000 W surge immunity is not required |
| SMCJ30A (Littelfuse) | Identical 30 V VWM, 5000 W PPPM, and SMC (DO-214AB) package; AEC-Q101 qualified; VC = 48.4 V same spec | Direct functional match with identical clamping behavior and thermal ratings | Valid alternative when dual-sourcing is needed; verify reel packaging (HM3 vs. TR) and revision-level compliance documentation |
Compared with SMBJ30A and SMCJ30A, the 5KASMC30AHM3_A/H offers identical surge capability to SMCJ30A but superior high-temperature margin (185 °C vs. 150–175 °C), making it preferred for under-hood deployments where ambient exceeds 125 °C.

FAQ
What is the maximum clamping voltage of the 5KASMC30AHM3_A/H under peak surge conditions?
The 5KASMC30AHM3_A/H has a maximum clamping voltage (VC) of 48.4 V when subjected to its rated peak pulse current of 103.3 A (10/1000 μs waveform). This value is measured per IEC 61000-4-5 and ANSI/IEEE C62.35 standards and ensures protected circuitry remains below critical voltage thresholds during worst-case transients.
Is the 5KASMC30AHM3_A/H suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the 5KASMC30AHM3_A/H is explicitly AEC-Q101 qualified, as confirmed in Vishay document 89432. It undergoes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge - making it approved for use in automotive power distribution, body electronics, and sensor systems.
What package type does the 5KASMC30AHM3_A/H use, and what are its key mechanical dimensions?
The 5KASMC30AHM3_A/H uses the SMC (DO-214AB) package: 7.75 mm × 6.22 mm body size with 2.62 mm height and 0.76 mm minimum lead thickness. Its standardized footprint enables drop-in compatibility with existing SMC layouts, and the cathode band provides unambiguous polarity marking for automated assembly.
How does the 5KASMC30AHM3_A/H perform at elevated temperatures?
The 5KASMC30AHM3_A/H maintains full functionality up to +185 °C junction temperature, with derated surge capability above 25 °C per Figure 2 in the datasheet. Its passivated anisotropic rectifier structure ensures stable VBR drift (αT = 0.090 %/°C) and minimal leakage increase - critical for engine bay or power-converter proximity mounting.
What is the standoff voltage and leakage current specification for the 5KASMC30AHM3_A/H at room temperature?
The 5KASMC30AHM3_A/H has a standoff voltage (VWM) of 30 V and a maximum reverse leakage current (IR) of 2.0 μA at 30 V and 25 °C. At elevated temperature (150 °C), leakage rises to 50 μA - still well within safe margins for 24 V system monitoring circuits and low-power sensor interfaces.
