Product details
Overview
5KASMC13AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SMC (DO-214AB) package, rated for 13 V stand-off voltage (VWM), 15.2 V nominal breakdown voltage (VBR), 5000 W peak pulse power (10/1000 μs), 232.6 A peak surge current (IPPM), and 21.5 V clamping voltage (VC) at IPPM - deployed for automotive sensor line protection and MOSFET gate safeguarding.
For engineers reviewing the 5KASMC13AHM3_A/I datasheet, 5KASMC13AHM3_A/I pinout, 5KASMC13AHM3_A/I application, or 5KASMC13AHM3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, TJ = 185 °C maximum junction temperature, MSL Level 1 rating, and halogen-free RoHS-compliant HM3 packaging with matte tin-plated leads.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under high-temperature transients. Its 100 °C/W junction-to-ambient thermal resistance and 20.8 °C/W junction-to-mount resistance support reliable operation on standard PCB pads without heatsinking in automotive-grade environments.
The device responds within picoseconds to ESD and lightning-induced surges, with low incremental surge resistance and excellent clamping ratio (VC/VBR ≈ 1.42). It meets JESD201 Class 2 whisker test requirements and is qualified per AEC-Q101 for under-hood and ADAS sensor applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before conduction begins |
| VBR (nom) | 15.2 V at 1 mA - precise breakdown threshold for predictable clamping onset |
| VC @ IPPM | 21.5 V at 232.6 A - clamped voltage during 5000 W surge, limiting downstream stress |
| PPPM | 5000 W (10/1000 μs) - robust energy absorption for ISO 7637-2 Pulse 1/2a/5a compliance |
| TJ max | +185 °C - enables placement near high-heat sources like power converters or engine control units |
| Polarity | Unidirectional - protects against positive-going transients only; cathode marked by band |
| MSL Level | Level 1 (260 °C peak reflow) - supports standard SMT assembly without moisture sensitivity concerns |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, matte tin-plated terminals, cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or signal return path; defines conduction direction for unidirectional clamping |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., sensor supply or data line); absorbs surge energy into ground |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation optimized design | Enables stable VBR drift < ±5 % over 1000 hrs at TJ = 150 °C, critical for long-life automotive modules |
| AEC-Q101 qualification | Validated for automotive use including HTOL, temperature cycling, and HTRB testing per stress test plan |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 10605 ESD), improving system immunity |
| MSL Level 1 rating | Eliminates bake-out requirement prior to reflow, reducing manufacturing cost and process complexity |
| Halogen-free & RoHS-compliant | Meets automotive OEM material compliance requirements (e.g., GMW3172, Ford WSS-M99P9999-A1) |
Applications
| Automotive Sensor Protection | Industrial Motor Drive I/O |
|---|---|
Use Scenario: Protecting LIN/CAN sensor lines (e.g., temperature, pressure, position sensors) from load-dump and inductive switching transients in engine compartments. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between signal line and chassis ground, absorbing >5 kV EFT and 100 A surge pulses. Use Value: Prevents latch-up or damage to automotive-grade microcontrollers and analog front-ends while maintaining signal integrity below 21.5 V clamping. | Use Scenario: Safeguarding digital I/O and feedback lines of servo drives and PLC outputs exposed to relay coil flyback and contact arcing. IC Role / Device Role / Timing Role: Transient suppression on 24 V DC control inputs, mounted directly at connector entry point. Use Value: Enables >100,000-cycle reliability under repeated 5000 W surge events without parameter shift or leakage degradation. |
| Automotive Power Supply Rail | Telecom Line Interface |
Use Scenario: Clamping 12 V battery rail against ISO 7637-2 Pulse 5a (load dump up to 60 V, 400 ms). IC Role / Device Role / Timing Role: Primary TVS in parallel with upstream fuse and downstream L-C filter, conducting surge current to ground. Use Value: Limits rail voltage to ≤21.5 V during 232.6 A peak surge, preventing overvoltage shutdown of PMICs and MCU regulators. | Use Scenario: Protecting RS-485 transceiver pins in outdoor base station equipment subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Secondary-level protection after gas discharge tube (GDT), handling residual fast transients. Use Value: Provides sub-nanosecond response and low clamping voltage to preserve signal eye diagram integrity on differential bus lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Same VWM (13 V) and package (SMB/DO-214AA), but lower PPPM (600 W) and IPPM (43.3 A) | Not suitable for ISO 7637-2 Pulse 5a or high-energy industrial surges | Select when cost-sensitive consumer applications require basic ESD/IEC 61000-4-2 protection only |
| SMCJ13A | Same SMC package and VWM, but higher VC (21.5 V same), lower TJ max (175 °C), and no AEC-Q101 qualification | Lacks automotive qualification and high-temperature reliability validation | Acceptable for industrial controls where AEC-Q101 is not mandated and ambient temperatures remain <125 °C |
Compared with SMBJ13A and SMCJ13A, the 5KASMC13AHM3_A/I delivers 8.3× higher peak pulse power, full AEC-Q101 certification, and guaranteed +185 °C operation - making it the only choice for safety-critical automotive power and sensor domains requiring zero derating at elevated temperatures.

FAQ
What is the clamping voltage of the 5KASMC13AHM3_A/I at its rated peak surge current?
The 5KASMC13AHM3_A/I has a maximum clamping voltage (VC) of 21.5 V when subjected to its peak pulse current (IPPM) of 232.6 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 89432 and ensures downstream ICs remain within safe operating voltage limits during surge events. The 5KASMC13AHM3_A/I maintains this clamping performance across its full operating temperature range.
Is the 5KASMC13AHM3_A/I qualified for automotive applications?
Yes, the 5KASMC13AHM3_A/I is fully AEC-Q101 qualified, having passed stress tests including high-temperature operating life (HTOL), temperature cycling, and highly accelerated stress testing (HAST). Its 185 °C maximum junction temperature rating and MSL Level 1 reflow compatibility make it suitable for under-hood and ADAS applications. The 5KASMC13AHM3_A/I is explicitly listed in Vishay's AEC-Q101 qualified product list (Document 89432, Revision 19-Jan-2024).
What does the "HM3_A/I" suffix indicate in 5KASMC13AHM3_A/I?
The "HM3" denotes Vishay's halogen-free, RoHS-compliant, AEC-Q101-qualified SMC package with matte tin-plated leads. "A" is the revision code; "I" specifies the packaging format: 13-inch diameter plastic tape and reel, with 3500 units per reel. This differs from "H", which indicates 7-inch reels (850 units). The 5KASMC13AHM3_A/I is optimized for high-volume SMT production with full traceability and no moisture sensitivity concerns.
Can the 5KASMC13AHM3_A/I replace the 5KASMC13A in existing designs?
Yes - the 5KASMC13AHM3_A/I is a direct replacement for the base 5KASMC13A, sharing identical electrical characteristics, thermal performance, and mechanical dimensions. The HM3 suffix adds halogen-free, RoHS, and AEC-Q101 compliance without altering functionality. No PCB layout or schematic changes are required when upgrading to 5KASMC13AHM3_A/I, and the 5KASMC13AHM3_A/I maintains full pin-to-pin compatibility with all variants in the 5KASMCxxA family.
What is the maximum reverse leakage current of the 5KASMC13AHM3_A/I at 13 V and 150 °C?
At 13 V stand-off voltage (VWM) and 150 °C junction temperature, the 5KASMC13AHM3_A/I exhibits a maximum reverse leakage current (ID) of 500 μA, as specified in Table 1 of Vishay Document 89432. This elevated leakage - compared to 10 μA at 25 °C - is fully characterized and accounted for in automotive thermal design margins. The 5KASMC13AHM3_A/I remains functional and reliable under these conditions without parameter shift or failure.
