Product details
Overview
SM6S13HE3/2D from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode in DO-218AB package, rated for 13 V stand-off voltage (VWM), 14.4–17.6 V breakdown (VBR), 23.8 V clamping at 193 A peak pulse current (10/1000 μs), and 4600 W peak pulse power. It is AEC-Q101 qualified and designed for automotive load dump protection in engine control units and body electronics.
For engineers reviewing the SM6S13HE3/2D datasheet, SM6S13HE3/2D pinout, SM6S13HE3/2D application, or SM6S13HE3/2D equivalent, key selection criteria include unidirectional polarity, 175 °C junction temperature rating, low leakage (<10 μA at VWM), 1.9 V forward voltage at 100 A surge, and compliance with ISO7637-2 load dump testing.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuitry, conducting only when reverse voltage exceeds its breakdown threshold. Its passivated anisotropic rectifier structure enables stable performance up to TJ = 175 °C and low leakage (<10 μA at 13 V, 25 °C).
The DO-218AB package features a metal heatsink acting as the anode terminal, enabling high thermal conductivity (RθJC = 0.95 °C/W) and robust 600 A non-repetitive forward surge capability (8.3 ms half-sine). It meets MSL Level 1 and JESD201 Class 2 whisker resistance.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5AT | DO-214AC (SMA) package; lower PPPM = 400 W; VC = 21.5 V @ 18.2 A | Not rated for AEC-Q101 or ISO7637-2; limited to non-automotive industrial use | Select only for cost-sensitive consumer or industrial designs where 175 °C operation and automotive qualification are unnecessary |

FAQ
What is the maximum clamping voltage of the SM6S13HE3/2D under standard test conditions?
The SM6S13HE3/2D has a maximum clamping voltage (VC) of 23.8 V when subjected to a 10/1000 μs waveform with a peak pulse current (IPPM) of 193 A. This value is measured at TC = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events. The SM6S13HE3/2D maintains this clamping performance across its full operating temperature range, supporting robust design margins in automotive applications.
Is the SM6S13HE3/2D qualified for automotive applications?
Yes, the SM6S13HE3/2D is AEC-Q101 qualified and explicitly designed for automotive use. It meets ISO7637-2 load dump surge requirements, operates reliably up to 175 °C junction temperature, and complies with MSL Level 1 reflow standards. The SM6S13HE3/2D also passes JESD201 Class 2 whisker testing and is RoHS-compliant-making it suitable for engine control units, body modules, and other under-hood electronics.
What does the "HE3/2D" suffix indicate in SM6S13HE3/2D?
The "HE3" suffix denotes RoHS-compliant construction and AEC-Q101 qualification; "2D" specifies the preferred packaging code for 13-inch plastic tape-and-reel delivery with 750 units per reel and anode orientation toward the sprocket hole. This packaging ensures compatibility with high-speed SMT placement equipment and supports traceable, controlled moisture exposure per J-STD-020. The SM6S13HE3/2D uses this standardized format for consistent manufacturing integration.
How does the DO-218AB package of the SM6S13HE3/2D improve thermal performance compared to standard SMC packages?
The DO-218AB package of the SM6S13HE3/2D integrates a metal heatsink as the anode terminal, achieving a typical junction-to-case thermal resistance (RθJC) of 0.95 °C/W-significantly lower than standard SMC (DO-214AB) packages (~2.5 °C/W). This allows the SM6S13HE3/2D to dissipate 6 W continuously on an infinite heatsink and sustain 4600 W transient pulses without thermal runaway. The SM6S13HE3/2D's heatsink-anode design directly transfers heat to the PCB copper, enhancing reliability in high-ambient environments.
Can the SM6S13HE3/2D be used in bidirectional configurations?
No, the SM6S13HE3/2D is unidirectional only, with polarity defined by its anode-heatsink construction. The datasheet explicitly states "Available in uni-directional polarity only," and the device conducts only when cathode voltage exceeds anode voltage by ≥VBR. For bidirectional protection, two SM6S13HE3/2D devices must be connected in series opposition-or a dedicated bidirectional TVS such as SMBJ13CA should be selected. The SM6S13HE3/2D's design does not support reverse-conduction capability.
