Product details
Overview
SMA6J13AHM3/61 from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor in SMA (DO-214AC) package, with 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR at IT = 1 mA), 20.4 V maximum clamping voltage at 29.4 A (10/1000 μs), 600 W peak pulse power rating, and 50 A peak forward surge current. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom power interfaces.
For engineers reviewing the SMA6J13AHM3/61 datasheet, SMA6J13AHM3/61 pinout, SMA6J13AHM3/61 application, or SMA6J13AHM3/61 equivalent, key selection criteria include clamping voltage margin vs. protected device VDS/VDD, unidirectional polarity compatibility with DC-biased rails, thermal resistance (RθJA = 120 °C/W), and MSL level 1 reflow suitability for high-volume SMT assembly.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VWM = 13 V, avalanches at VBR = 14.4–15.9 V, and clamps to ≤20.4 V under 29.4 A (10/1000 μs) surge. Its dynamic resistance RD = 0.153 Ω directly determines clamping rise above VBR during fast transients.
Designed for PCB-level protection of DC power rails and low-speed signal lines, it features matte tin-plated leads compliant with J-STD-002 solderability, meets UL 94 V-0 flammability, and supports automated placement in 7" tape-and-reel (61 code). The M3 suffix confirms halogen-free, RoHS-compliant, industrial-grade construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse voltage before leakage exceeds 0.2 μA; sets upper limit for safe DC rail operation. |

| VC @ IPP | 20.4 V at 29.4 A (10/1000 μs) - Clamping voltage seen by protected circuit during standard surge; must be below IC absolute max rating. |
| PPPM (10/1000 μs) | 600 W - Peak transient energy absorption capability under standardized long-duration surge waveform. |
| ID @ VWM | ≤0.2 μA - Reverse leakage at rated stand-off voltage; negligible power loss and noise injection in standby. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance on standard 5.0 mm × 5.0 mm copper pads; defines derating above 50 °C ambient. |
| Polarity | Unidirectional - Cathode-band marked; suitable only for DC-biased or positive-rail protection, not AC or bidirectional signals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ13A | VWM = 13 V, VC = 21.5 V @ 27.7 A (10/1000 μs), RθJA = 110 °C/W, E3-only (not halogen-free) | Higher clamping voltage reduces margin for 15 V logic; lacks M3 halogen-free certification required in EU industrial gear | Select when cost sensitivity outweighs halogen-free compliance and tighter clamping is noncritical. |
| ON Semiconductor SMA6J13AHE3/A/H | VWM = 13 V, VC = 20.4 V @ 29.4 A, same clamping, but E3 suffix (RoHS, not halogen-free), 7" reel code 61 identical | Matches electrical specs exactly but fails JESD 201 class 2 whisker test and halogen-free requirements for harsh environments | Choose only for legacy designs where M3 compliance is not mandated and supply chain prefers ON Semi sourcing. |
Compared with SMA6J13AHM3/61, SMAJ13A offers slightly lower thermal resistance but sacrifices clamping margin and halogen-free status, while SMA6J13AHE3/A/H matches clamping performance but omits critical M3 material qualifications for industrial deployment.

FAQ
What is the maximum clamping voltage of the SMA6J13AHM3/61 under a 10/1000 μs surge?
The SMA6J13AHM3/61 has a maximum clamping voltage (VC) of 20.4 V when subjected to a 10/1000 μs surge current of 29.4 A. This value is measured per the conditions specified in the Vishay datasheet (Document Number: 89460), with the device mounted on 5.0 mm × 5.0 mm copper pads. The SMA6J13AHM3/61 achieves this clamping performance using its defined dynamic resistance of 0.153 Ω.
Is the SMA6J13AHM3/61 suitable for bidirectional signal line protection?
No, the SMA6J13AHM3/61 is a unidirectional TVS diode, as confirmed by Vishay's documentation stating "Available in unidirectional polarity only" and specifying cathode-band marking. It blocks reverse current above VWM = 13 V but conducts only in the forward direction during clamping. For bidirectional protection (e.g., USB, RS-485), a symmetric device like SMA6J13CA would be required-not the SMA6J13AHM3/61.
Does the M3 suffix in SMA6J13AHM3/61 indicate halogen-free construction?
Yes, the M3 suffix in SMA6J13AHM3/61 explicitly denotes halogen-free, RoHS-compliant, industrial-grade construction per Vishay's ordering nomenclature. This is verified in the "MECHANICAL DATA" section of the datasheet, which states "Base P/N-M3 - halogen-free, RoHS-compliant, and industrial grade", and further confirmed by compliance with JESD 201 class 2 whisker testing.
What is the thermal resistance junction-to-ambient (RθJA) for the SMA6J13AHM3/61?
The SMA6J13AHM3/61 has a typical thermal resistance of RθJA = 120 °C/W when mounted on the minimum recommended PCB pad layout (5.0 mm × 5.0 mm copper pads per terminal), as stated in the "THERMAL CHARACTERISTICS" table of the Vishay datasheet. This value governs power derating above TA = 50 °C and must be used to calculate safe operating area under sustained surge duty cycles.
Can the SMA6J13AHM3/61 withstand lead-free reflow soldering?
Yes, the SMA6J13AHM3/61 is rated for lead-free reflow with MSL level 1 per J-STD-020 and a maximum peak temperature of 260 °C, as documented in the "FEATURES" section. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the molding compound complies with UL 94 V-0 flammability-making it fully compatible with standard Pb-free SMT processes.
