Product details
Overview
SMA5J13CAHM3/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 13 V standoff voltage (VWM), 14.4–15.9 V breakdown voltage (VBR), 500 W peak pulse power (10/1000 μs), clamping voltage of 21.5 V at 23.3 A, and operates from −55 °C to +150 °C. It is used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J13CAHM3/H datasheet, SMA5J13CAHM3/H pinout, SMA5J13CAHM3/H application, or SMA5J13CAHM3/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data, clamping performance under standardized surge waveforms, and halogen-free RoHS-compliant sourcing details.
Technical Context
This bidirectional TVS diode uses a glass-passivated silicon junction to achieve fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of ESD, lightning-induced transients, and inductive switching spikes. Its symmetrical breakdown behavior ensures identical clamping in both polarities, critical for AC-coupled or floating signal paths.
The device is rated for 500 W peak pulse power per 10/1000 μs waveform with derating above 25 °C, and exhibits a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 5.0 mm × 5.0 mm copper pads - confirming suitability for compact PCB layouts without forced cooling.

|---|---|
Use Scenario: Protecting analog output lines (e.g., 4–20 mA current loops) and LIN bus interfaces in engine control modules from load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across signal line and ground to shunt surge energy before reaching precision DAC or op-amp input stages. Use Value: Maintains signal integrity during 12 V system transients by limiting voltage excursion to ≤21.5 V, preventing latch-up or parametric shift in connected ASICs. |
Use Scenario: Safeguarding digital input channels on programmable logic controllers exposed to field wiring surges from motor contactors or solenoid coils. IC Role / Device Role / Timing Role: Primary surge suppression element located at connector entry point, upstream of optocoupler isolation barrier. Use Value: Enables reliable operation in harsh factory environments by absorbing 500 W surges without degradation, extending mean time between failures (MTBF) of I/O modules. |
| Telecom Line Interface Protection | Consumer Power Adapter ESD Guard |
Use Scenario: Shielding RS-485 transceiver pins in base station backhaul units from induced lightning surges on long outdoor cable runs. IC Role / Device Role / Timing Role: Symmetrical TVS pair (one per differential line) referenced to common ground, providing balanced clamping without skew. Use Value: Preserves differential signaling integrity by maintaining <100 ps inter-line timing skew during clamping, avoiding false edge detection in UART or Modbus traffic. |
Use Scenario: Adding secondary-level surge protection on DC output rails of USB-C PD adapters after primary SMPS stage. IC Role / Device Role / Timing Role: Final-stage clamp limiting output overvoltage to safe levels during fault conditions like feedback loop failure or Zener short. Use Value: Prevents damage to connected mobile devices by capping output to 21.5 V even during worst-case 500 W surge, satisfying UL 62368-1 transient limits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J13CAHE3/H | Same electrical specs and AEC-Q101 qualification; RoHS-compliant but not halogen-free; uses standard tin plating instead of matte tin. | Acceptable for non-automotive industrial use where halogen content is unrestricted; slightly lower whisker resistance per JESD 201 Class 2. | Select SMA5J13CAHE3/H only if halogen-free requirement is waived and cost optimization is prioritized over automotive compliance rigor. |
| SMA6J13CAHM3/H | Higher 600 W peak pulse power rating; identical VWM, VBR, and package; larger junction area increases thermal mass and reduces RθJA to 70 °C/W. | Better suited for repeated surge exposure (e.g., industrial motor drives) or higher ambient temperature enclosures (>105 °C). | Choose SMA6J13CAHM3/H when system-level testing reveals marginal margin with 500 W rating or when extended lifetime under cyclic stress is required. |
Compared with SMA5J13CAHM3/H, SMA5J13CAHE3/H offers identical protection performance without halogen-free assurance, while SMA6J13CAHM3/H provides 20 % higher surge capacity and improved thermal resilience - making it preferable for high-reliability or thermally constrained deployments.

FAQ
What is the clamping voltage of the SMA5J13CAHM3/H under full-rated surge current?
The SMA5J13CAHM3/H clamps to a maximum of 21.5 V at its peak pulse current of 23.3 A (10/1000 μs waveform). This value is measured and guaranteed per Vishay's datasheet revision 09-Jan-2024, Document Number 88875, and defines the upper voltage limit imposed on protected circuitry during standardized surge events. The SMA5J13CAHM3/H maintains this clamping performance across its full operating temperature range.
Is the SMA5J13CAHM3/H suitable for automotive applications?
Yes, the SMA5J13CAHM3/H is AEC-Q101 qualified and explicitly designated for automotive use, as confirmed by its HM3 suffix and documentation in Vishay's official datasheet. It supports under-hood and cabin applications including engine control units, ADAS sensor interfaces, and body control modules. The SMA5J13CAHM3/H meets all stress test requirements defined in AEC-Q101, including temperature cycling, humidity bias, and mechanical shock.
Does the SMA5J13CAHM3/H have polarity markings?
No, the SMA5J13CAHM3/H does not feature polarity markings because it is a bidirectional TVS diode. Unlike unidirectional variants (e.g., SMA5J13A), the SMA5J13CAHM3/H has symmetrical electrical characteristics in both directions and no cathode band. This allows flexible PCB placement across AC-coupled or floating signal paths without orientation constraints.
What is the thermal resistance of the SMA5J13CAHM3/H?
The SMA5J13CAHM3/H 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, as specified in Vishay's datasheet. This value assumes standard JEDEC test conditions and guides thermal design for sustained surge duty cycles. For higher-power or elevated ambient scenarios, the SMA5J13CAHM3/H may require additional copper pour or airflow.
How does the HM3 suffix affect the SMA5J13CAHM3/H specification?
The HM3 suffix on SMA5J13CAHM3/H indicates halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD 201 Class 2 whisker resistance. It also confirms AEC-Q101 qualification. These attributes distinguish it from E3 (RoHS only) and HE3 (AEC-Q101, non-halogen-free) variants. The core electrical parameters - including VWM, VBR, and PPPM - remain identical across all suffixes for the SMA5J13CAHM3/H family.
