Product details
Overview
SMA6J13AHM3/5A from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 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 operates from –55 °C to +150 °C junction temperature - used to protect MOSFETs and ICs in industrial power supplies.
For engineers reviewing the SMA6J13AHM3/5A datasheet, SMA6J13AHM3/5A pinout, SMA6J13AHM3/5A application, or SMA6J13AHM3/5A equivalent, key selection criteria include clamping voltage at rated surge current, unidirectional polarity compatibility with DC-biased rails, thermal resistance (RθJA = 120 °C/W), and halogen-free RoHS-compliant M3 suffix packaging for high-reliability PCB assembly.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device triggered above its reverse breakdown threshold, with dynamic resistance (RD = 0.153 Ω) enabling low-voltage overshoot during transient events. Its 8/20 μs waveform capability supports 4000 W surge handling, while the 10/1000 μs rating delivers 600 W for longer-duration transients such as inductive switch-off spikes.
The SMA6J13AHM3/5A exhibits a positive voltage temperature coefficient (αT = 8.4 × 10⁻⁴ /°C), meaning VBR increases linearly with junction temperature. Its leakage current remains ≤0.2 μA at 13 V (VWM), ensuring minimal standby power loss in always-on circuits like sensor bias rails or microcontroller I/O protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before significant conduction begins; sets upper limit for protected line DC bias. |
| VBR (min/max) | 14.4 V / 15.9 V at IT = 1 mA - Confirmed breakdown range ensures predictable turn-on across production lot and temperature. |
| VC at IPP | 20.4 V at 29.4 A (10/1000 μs) - Clamping voltage defines worst-case overvoltage seen by downstream ICs during surge. |
| PPPM (10/1000 μs) | 600 W - Sustained transient energy absorption capacity under standard lightning-surge test waveform. |
| RθJA | 120 °C/W - Thermal resistance from junction to ambient on standard 5.0 mm × 5.0 mm copper pads; dictates derating above 50 °C ambient. |
| Polarity | Unidirectional - Requires correct orientation relative to DC rail polarity; cathode band denotes terminal connected to protected circuit ground. |
| Package | SMA (DO-214AC) - Surface-mount outline with 2.54 mm lead pitch; compatible with automated pick-and-place and reflow soldering per J-STD-020 MSL level 1. |
Pinout & Package
SMA6J13AHM3/5A uses the SMA (DO-214AC) surface-mount package: molded epoxy case with matte tin-plated leads, UL 94 V-0 flammability rating, and cathode indicated by a color band. Dimensions: 4.50 mm × 2.79 mm × 2.20 mm (L × W × H), with 0.110 mm (2.79 mm) lead length and 0.066 mm (1.68 mm) minimum terminal width.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Connected to protected line (e.g., +12 V rail) | Reverse-biased during normal operation; conducts only when line voltage exceeds VBR, shunting surge current to ground. |
| Cathode | Connected to reference ground (GND) | Provides low-impedance path to ground during clamping; must be routed with minimal inductance to preserve clamping speed and effectiveness. |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-free, RoHS-compliant construction | M3 suffix confirms compliance with JEDEC JESD201 Class 2 whisker resistance and environmental regulations for industrial-grade deployment. |
| Low clamping ratio (VC/VBR ≈ 1.33) | Ensures tight overvoltage control - critical for protecting 15 V-tolerant logic interfaces or gate drivers without overdesigning downstream TVS stages. |
| MSL Level 1 moisture sensitivity | Enables unlimited floor life before reflow; eliminates bake-out requirement and simplifies SMT line logistics for high-volume manufacturing. |
| High IFSM rating (50 A) | Withstands repetitive 8.3 ms half-sine surges - suitable for motor drive power stage protection where commutation spikes recur frequently. |
| Stable leakage (<0.2 μA at VWM) | Minimizes quiescent current draw in battery-powered sensor nodes or always-on monitoring circuits without compromising protection integrity. |
Applications
| Industrial Motor Drive Protection | Automotive Body Control Module (BCM) Power Input |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J13AHE3/5A | Same electrical specs; E3 suffix indicates RoHS-compliant, non-halogen-free construction (not JESD201 Class 2 whisker tested). | Approved for commercial-grade industrial use but not qualified for extended-temperature automotive or aerospace deployments requiring whisker resistance. | Select SMA6J13AHE3/5A only if halogen-free content is not mandated and whisker testing is outside qualification scope. |
| SMCJ13A-M3/57T | Higher power rating (1500 W at 10/1000 μs), larger SMC (DO-214AB) package, same VWM/VBR/VC values, and identical M3 halogen-free compliance. | Used where higher surge margin is required (e.g., outdoor telecom cabinets), but requires PCB layout change due to 7.11 mm × 6.22 mm footprint vs. SMA's 4.50 mm × 2.79 mm. | Choose SMCJ13A-M3/57T when system-level surge testing exceeds 600 W requirements and board space allows larger package. |
Compared with SMA6J13AHM3/5A, SMA6J13AHE3/5A offers identical clamping performance but lacks halogen-free certification and whisker resistance, while SMCJ13A-M3/57T provides 2.5× higher surge power in a physically incompatible package - making SMA6J13AHM3/5A optimal for space-constrained, high-reliability industrial designs needing verified halogen-free compliance.

FAQ
What is the maximum clamping voltage of the SMA6J13AHM3/5A at its rated peak pulse current?
The SMA6J13AHM3/5A has a maximum clamping voltage (VC) of 20.4 V at 29.4 A peak pulse current under the 10/1000 μs waveform. This value is measured per the conditions specified in the Vishay datasheet (Document Number: 89460, Rev. 09-Jan-2024) and reflects worst-case overvoltage seen by protected circuitry during standardized surge events. The SMA6J13AHM3/5A maintains this clamping performance across its full operating temperature range when mounted per recommended pad layout.
Does the SMA6J13AHM3/5A meet automotive qualification standards such as AEC-Q200?
The SMA6J13AHM3/5A is not AEC-Q200 qualified. It is an industrial-grade TVS diode with operating temperature range of –55 °C to +150 °C and M3 halogen-free RoHS compliance, but Vishay does not list it in their AEC-Q200 qualified product portfolio. For automotive applications, designers should verify system-level validation and consider alternatives explicitly certified to AEC-Q200 - the SMA6J13AHM3/5A itself is intended for industrial, telecom, and consumer systems where full automotive qualification is not mandated.
How does the M3 suffix in SMA6J13AHM3/5A differ from the E3 suffix?
The M3 suffix in SMA6J13AHM3/5A indicates halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance testing, whereas E3 denotes RoHS-compliant but non-halogen-free material. Both meet RoHS, but only M3 satisfies halogen-free requirements (per IEC 61249-2-21) and passes accelerated whisker growth testing - critical for long-life, high-reliability applications exposed to thermal cycling. The SMA6J13AHM3/5A thus provides enhanced metallurgical stability versus SMA6J13AHE3/5A.
Can the SMA6J13AHM3/5A be used in bidirectional transient suppression applications?
No, the SMA6J13AHM3/5A is strictly unidirectional and cannot suppress transients on AC-coupled or bipolar signal lines. Its internal structure supports conduction only in reverse bias above VBR; forward conduction occurs at ~3.5 V (VF at 25 A), which is insufficient for symmetrical clamping. For bidirectional protection, a dedicated bidirectional TVS like SMA6J13CA must be selected - the SMA6J13AHM3/5A is designed exclusively for DC rails with defined polarity.
What is the thermal resistance junction-to-ambient (RθJA) for the SMA6J13AHM3/5A, and how does it affect derating?
The SMA6J13AHM3/5A has a typical RθJA of 120 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. This value determines power derating above TA = 50 °C: for example, at 75 °C ambient, the allowable power drops to ~2.7 W (calculated via linear derating curve in Fig. 2 of datasheet 89460). Proper pad design is essential - the SMA6J13AHM3/5A's thermal performance degrades significantly with smaller copper areas or lack of thermal vias.
