Product details
Overview
SMA5J13AHM3/I 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 stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR at 1 mA), 500 W peak pulse power (10/1000 µs), 23.3 A peak pulse current (IPPM), and clamps to ≤21.5 V at rated surge. It is widely used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the SMA5J13AHM3/I datasheet, SMA5J13AHM3/I pinout, SMA5J13AHM3/I application, or SMA5J13AHM3/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 80 °C/W), junction temperature range (–55 to +150 °C), and halogen-free RoHS-compliant construction per JESD201 Class 2 whisker test.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device triggered by transient overvoltage events exceeding its VWM of 13 V. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced surges.
Designed for surface-mount assembly on 5.0 mm × 5.0 mm copper pads, it delivers 500 W peak pulse power under standardized 10/1000 µs waveform conditions and supports unidirectional surge currents up to 40 A (IFSM, 8.3 ms half-sine). Its MSL Level 1 rating confirms suitability for lead-free reflow up to 260 °C peak.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and ISO 7637-2 pulses.

Use Value: Limits voltage seen by downstream DC-DC converters and microcontrollers to ≤21.5 V during 500 W surges, preventing latch-up or damage. | Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA current loops) in factory automation sensors. IC Role / Device Role / Timing Role: TVS connected across signal and return path to absorb ESD and inductive switching spikes. Use Value: Maintains signal integrity by clamping transients within 1 ns while adding <1 pF capacitance, avoiding bandwidth degradation. |

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/I | Same electrical specs; RoHS-compliant but not halogen-free; AEC-Q101 qualified; uses E3 suffix instead of HM3 | Identical automotive use cases; differs only in material composition (halogen content) | Select SMA5J13AHM3/I when halogen-free compliance is required per OEM specification |
| SMA6J13A-M3 | 600 W PPPM, same VWM/VBR; larger SMA package variant with higher surge rating | Preferred where higher single-pulse energy (e.g., ISO 16750-2 Pulse 5a) must be absorbed | Choose SMA6J13A-M3 if system-level testing requires >500 W surge margin; otherwise SMA5J13AHM3/I suffices for standard 500 W duty |
Compared with SMA5J13AHE3/I, SMA5J13AHM3/I adds halogen-free compliance without sacrificing AEC-Q101 qualification or electrical performance; versus SMA6J13A-M3, it trades 100 W peak power for identical footprint and lower cost-ideal for space-constrained automotive modules meeting baseline ISO 7637-2 immunity.

FAQ
What is the clamping voltage of the SMA5J13AHM3/I under full-rated surge conditions?
The SMA5J13AHM3/I clamps to a maximum of 21.5 V when subjected to its rated peak pulse current of 23.3 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 and guarantees predictable overvoltage limiting for downstream components. The clamping performance is validated across the full operating temperature range (–55 °C to +150 °C), making SMA5J13AHM3/I suitable for under-hood automotive applications where thermal stability is critical.
Is SMA5J13AHM3/I qualified for automotive use?
Yes, SMA5J13AHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance. It has passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT), confirming suitability for automotive powertrain and body electronics. The "HM3" designation explicitly denotes AEC-Q101 qualification per Vishay's ordering nomenclature.
What is the difference between SMA5J13AHM3/I and SMA5J13AHE3/I?
SMA5J13AHM3/I and SMA5J13AHE3/I share identical electrical specifications (VWM = 13 V, VBR = 14.4–15.9 V, PPPM = 500 W) and AEC-Q101 qualification, but differ in material composition: HM3 denotes halogen-free construction, while HE3 is RoHS-compliant without halogen-free assurance. Both use the same SMA (DO-214AC) package and are pin-to-pin interchangeable. The choice depends on OEM material declarations-SMA5J13AHM3/I satisfies stricter halogen-free mandates.
Does SMA5J13AHM3/I support bidirectional transient suppression?
No, SMA5J13AHM3/I is strictly unidirectional, as indicated by the "A" (not "CA") suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., SMA5J13CA) and lack polarity marking. Attempting to use SMA5J13AHM3/I for bidirectional protection will result in forward conduction during negative transients, potentially damaging the device or failing to suppress. Always match suffix to system polarity requirements.
What is the thermal resistance and recommended PCB layout for SMA5J13AHM3/I?
SMA5J13AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain reliability under repeated surges, Vishay specifies this minimum pad area. Reducing pad size increases RθJA, risking thermal runaway during high-duty-cycle transients. The device's MSL Level 1 rating permits standard reflow without pre-baking, provided moisture-sensitive packaging is handled per J-STD-020.
