Product details
Overview
SMA5J13AHM3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on power and signal lines. It features a 13 V standoff voltage (VWM), 14.4–15.9 V breakdown range (VBR), 23.3 A peak pulse current (IPPM), 21.5 V clamping voltage (VC) at IPPM, and 500 W peak pulse power (PPPM). It is widely used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the SMA5J13AHM3/H datasheet, SMA5J13AHM3/H pinout, SMA5J13AHM3/H application, or SMA5J13AHM3/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification (via HM3 suffix), halogen-free RoHS compliance, 150 °C max junction temperature, and compatibility with automated SMT placement on standard 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold, limiting transient overvoltages to ≤21.5 V under 10/1000 µs surge conditions. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1 ns), critical for protecting sensitive downstream components.
The SMA5J13AHM3/H is rated for 500 W peak pulse power with derating above 25 °C ambient, exhibits 80 °C/W junction-to-ambient thermal resistance, and supports 40 A non-repetitive forward surge current (IFSM) - enabling robust protection against inductive switching transients and ESD events in DC power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC operating margin. |
| VBR (min/max) | 14.4 V / 15.9 V - breakdown occurs within this range at 1 mA test current; ensures predictable turn-on threshold. |
| VC @ IPPM | 21.5 V - clamped voltage during 23.3 A 10/1000 µs surge; determines maximum stress imposed on protected circuitry. |
| PPPM | 500 W - peak pulse power handling capability; defines energy absorption capacity per transient event. |
| IPPM | 23.3 A - maximum non-repetitive surge current supported at VC; sets protection level for common lightning/inductive spikes. |
| TJ max | +150 °C - maximum junction temperature; enables reliable operation in under-hood automotive and industrial environments. |
| Package | SMA (DO-214AC) - surface-mount package with 0.208" × 0.157" footprint; compatible with standard reflow profiles and J-STD-020 MSL Level 1. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with matte tin-plated leads, polarity indicated by cathode band. Mounting requires minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-side reference | Connected to ground or lower-potential rail in unidirectional configuration; forms return path during clamping. |
| Cathode (banded end) | Reverse voltage sensing / clamping node | Connected to protected line (e.g., 12 V supply); avalanche conduction initiates here when VREV > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, body electronics, and ADAS modules. |
| Halogen-free & RoHS-compliant | HM3 suffix denotes halogen-free molding compound and lead finish - meets automotive OEM environmental requirements and JEDEC JESD201 Class 2 whisker resistance. |
| Low incremental surge resistance | Enables tighter VC/VBR ratio (21.5 V / 14.4 V ≈ 1.49), minimizing let-through voltage during fast transients compared to higher-Rsurge TVS devices. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life before reflow; no baking required - simplifies SMT line logistics and reduces assembly risk. |
| Glass-passivated junction | Provides stable leakage (<1.0 µA at 13 V), consistent VBR, and long-term parameter stability across temperature and lifetime. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J13AHE3/H | Same electrical specs (VWM, VBR, VC, PPPM), but RoHS-compliant without halogen-free requirement; uses standard SnPb-free matte tin plating. | Approved for commercial/industrial use only; not AEC-Q101 qualified - unsuitable for automotive under-hood deployment. | Select SMA5J13AHE3/H where halogen-free content is not mandated and automotive qualification is unnecessary. |
| SMA6J13A-M3/H | Higher 600 W PPPM, same VWM/VBR, but larger SMA package variant (DO-214AC with thicker leads); slightly higher VC (22.0 V). | Supports higher surge energy; better suited for harsher environments like railway or heavy industrial mains-connected equipment. | Choose SMA6J13A-M3/H when system-level surge testing exceeds 500 W requirements or longer surge duration must be accommodated. |
Compared with SMA5J13AHM3/H, SMA5J13AHE3/H offers identical clamping performance without halogen-free assurance or automotive qualification, while SMA6J13A-M3/H trades minor VC increase for +100 W surge headroom - making the HM3 variant optimal for cost-sensitive, AEC-Q101–required automotive power nodes.

FAQ
What is the clamping voltage of the SMA5J13AHM3/H under a 10/1000 µs surge?
The SMA5J13AHM3/H has a maximum clamping voltage (VC) of 21.5 V when subjected to its rated peak pulse current of 23.3 A using the standardized 10/1000 µs waveform. This value is measured at TA = 25 °C with specified PCB pad layout and represents the upper limit of voltage imposed on protected circuitry during surge events - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings.
Is the SMA5J13AHM3/H qualified for automotive applications?
Yes, the SMA5J13AHM3/H is AEC-Q101 qualified, as confirmed by the HM3 suffix and Vishay's official documentation. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, validating its suitability for automotive powertrain, chassis, and body electronics where reliability under extreme thermal and electrical stress is mandatory.
What does the "HM3" suffix indicate in SMA5J13AHM3/H?
The "HM3" suffix in SMA5J13AHM3/H denotes halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance. It also signifies AEC-Q101 qualification and packaging in 7" tape-and-reel (H code). This distinguishes it from E3 (RoHS only) and HE3 (AEC-Q101 + RoHS, non-halogen-free) variants.
How does the SMA5J13AHM3/H differ from bidirectional TVS diodes like SMA5J13CA?
The SMA5J13AHM3/H is unidirectional and functions only during reverse-biased transients, with a forward voltage drop (~3.5 V at 25 A) and cathode band marking. In contrast, SMA5J13CA is bidirectional, symmetric in both polarities, lacks polarity marking, and is used where AC-coupled or dual-polarity protection is needed - such as data line or audio interface protection.
What is the maximum operating temperature for the SMA5J13AHM3/H?
The SMA5J13AHM3/H has a maximum junction temperature (TJ) rating of +150 °C and an operating junction/storage temperature range of -55 °C to +150 °C. This allows reliable deployment in under-hood automotive environments and industrial enclosures where ambient temperatures exceed 100 °C, provided thermal design accounts for its 80 °C/W junction-to-ambient resistance.
