Product details
Overview
5KASMC36AHM3/9A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for high-energy surge protection of sensitive electronics. It features 5000 W peak pulse power (10/1000 µs), 40.0–44.2 V breakdown voltage (VBR), 36 V stand-off voltage (VWM), and clamps to ≤58.1 V at 86.1 A peak surge current - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the 5KASMC36AHM3/9A datasheet, 5KASMC36AHM3/9A pinout, 5KASMC36AHM3/9A application, or 5KASMC36AHM3/9A equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C maximum junction temperature, low incremental surge resistance, and MSL Level 1 moisture sensitivity rating for lead-free reflow compatibility.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under repetitive transient stress. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until breakdown threshold is exceeded.
Rated for 5000 W peak pulse power with 10/1000 µs waveform and derated above 25 °C ambient, it maintains reliable operation up to TJ = 185 °C - meeting automotive-grade thermal and reliability requirements per AEC-Q101.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - maximum continuous reverse operating voltage before leakage exceeds 2 µA; defines safe DC bias margin. |
| VBR (min/max) | 40.0 V / 44.2 V at 1 mA test current - ensures predictable breakdown onset across production lot. |
| VC @ IPPM | ≤58.1 V at 86.1 A - clamping voltage limits downstream IC stress during 5000 W surge events. |
| PPPM | 5000 W (10/1000 µs) - protects against high-energy transients from inductive switching or lightning-induced surges. |
| TJ max | 185 °C - supports under-hood automotive applications and high-ambient industrial environments. |
| Package | DO-214AB (SMCJ) - industry-standard SMT outline with 7.75 mm × 6.22 mm footprint and J-STD-020-compliant matte tin leads. |
| Qualification | AEC-Q101 qualified - validated for automotive electronic systems requiring zero defects and long-term reliability. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to circuit ground or lowest potential node; carries full surge current during clamping. |
| Cathode | High-side connection point | Marked by color band; connected to protected line (e.g., 36 V rail or sensor output); blocks reverse leakage below VWM. |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier design reduces parameter drift over temperature and lifetime. |
| Thermal robustness | 185 °C max junction temperature enables operation in engine control units and power converters. |
| Surge response | Sub-nanosecond response time ensures clamping before transient energy damages downstream MOSFETs or ICs. |
| Mounting reliability | Matte tin-plated leads meet J-STD-002 solderability and JESD22-B102 whisker resistance Class 2. |
| Process compliance | Halogen-free, RoHS-compliant, and AEC-Q101 qualified - satisfies Tier-1 automotive supply chain requirements. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed microcontroller power inputs in body control modules against load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between VIN and GND to limit transient overvoltage to safe levels. Use Value: Clamps 5000 W surges to ≤58.1 V, preventing latch-up or permanent damage to 5 V LDO regulators and MCU cores. |
Use Scenario: Safeguarding analog outputs of pressure sensors in factory automation PLC I/O modules exposed to EMI and relay coil kickback. IC Role / Device Role / Timing Role: Standoff-rated TVS on 4–20 mA current loop or 0–10 V analog output line, referenced to system ground. Use Value: Maintains <2 µA leakage at 36 V, preserving signal integrity while suppressing >1 kV transients without affecting calibration. |
| Telecom Power Supply Input | Consumer Device USB Port Protection |
Use Scenario: Front-end surge suppression on AC/DC adapter input stage in telecom base station power supplies. IC Role / Device Role / Timing Role: Primary-level TVS on bulk DC bus (e.g., 48 V) to absorb lightning-induced surges before DC-DC conversion. Use Value: Withstands repeated 5000 W pulses without degradation, supporting EN 61000-4-5 Level 4 compliance. |
Use Scenario: Overvoltage protection on VBUS line of USB 2.0 host ports in smart home hubs subjected to ESD and hot-plug transients. IC Role / Device Role / Timing Role: Unidirectional clamp between VBUS and GND, sized to handle 36 V standoff and fast 10/1000 µs surges. Use Value: Low capacitance (<100 pF at 0 V) avoids signal integrity loss on 480 Mbps data lines while providing 5000 W surge immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/57 | Same DO-214AC (SMA) package; lower PPPM = 400 W; VC = 58.1 V at 6.8 A. | Not suitable for 5000 W surge environments; limited to low-energy consumer interfaces. | Select only when space-constrained layouts require SMA footprint and surge energy is ≤400 W. |
| SMCJ36A | Same DO-214AB (SMCJ) package; identical VWM/VBR/VC; PPPM = 1500 W (not 5000 W). | Lacks capability for high-energy automotive load dump; requires parallel staging for equivalent energy handling. | Choose if cost sensitivity outweighs peak power requirement and system-level surge testing confirms 1500 W sufficiency. |
Compared with SMAJ36A-E3/57 and SMCJ36A, the 5KASMC36AHM3/9A delivers 3.3× higher peak pulse power than SMCJ36A and 12.5× more than SMAJ36A - enabling single-device protection in AEC-Q101-compliant automotive power domains without layout redesign or paralleling.

FAQ
What is the maximum clamping voltage of the 5KASMC36AHM3/9A under rated surge conditions?
The 5KASMC36AHM3/9A has a maximum clamping voltage (VC) of 58.1 V when subjected to its rated peak pulse current of 86.1 A (10/1000 µs waveform). This value is measured per Figure 3 in the Vishay datasheet 89432 and ensures downstream components remain within safe operating voltage limits during high-energy transients.
Is the 5KASMC36AHM3/9A suitable for automotive applications?
Yes, the 5KASMC36AHM3/9A is AEC-Q101 qualified and rated for TJ = 185 °C, making it suitable for under-hood automotive applications such as engine control units, body electronics, and ADAS power supplies. Its DO-214AB package meets J-STD-020 reflow profiles, and the HM3 suffix confirms halogen-free, RoHS-compliant construction.
What does the "HM3/9A" suffix indicate in 5KASMC36AHM3/9A?
The "HM3" denotes Vishay's halogen-free, RoHS-compliant, AEC-Q101-qualified base part variant with matte tin plating and JESD201 Class 2 whisker resistance. The "/9A" specifies packaging: 3500-unit quantity on 13-inch plastic tape and reel - distinct from /57 (850 units on 7-inch reel) and critical for automated SMT line setup.
How does the 5KASMC36AHM3/9A compare to standard SMCJ-series TVS diodes?
Unlike generic SMCJ36A parts rated for 1500 W, the 5KASMC36AHM3/9A delivers 5000 W peak pulse power (10/1000 µs) while maintaining identical VWM, VBR, and DO-214AB package. This enables direct replacement in high-surge applications without changing PCB layout - provided thermal management supports the higher energy dissipation.
What is the reverse leakage current specification for the 5KASMC36AHM3/9A at 36 V and 150 °C?
At VWM = 36 V and TJ = 150 °C, the 5KASMC36AHM3/9A exhibits a maximum reverse leakage current (ID) of 20 µA, as specified in Table 1 of Vishay document 89432. This elevated leakage at high temperature remains well within design margins for most automotive and industrial protection circuits.
