Product details
Overview
SM8S13A-001HE3/2D from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for automotive load dump protection. It features a 14.4 V minimum breakdown voltage (VBR), 13.0 V stand-off voltage (VWM), 21.5 V maximum clamping voltage at 307 A peak pulse current, 6600 W peak pulse power (10/1000 μs), and operates up to TJ = 175 °C - enabling robust protection in engine control units and body electronics.
For engineers reviewing the SM8S13A-001HE3/2D datasheet, SM8S13A-001HE3/2D pinout, SM8S13A-001HE3/2D application, or SM8S13A-001HE3/2D equivalent, key selection criteria include unidirectional polarity, DO-218AB package thermal performance (RθJC = 0.90 °C/W), ISO7637-2 compliance, AEC-Q101 qualification, and low leakage (≤10 μA at VWM).
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for high-temperature stability and surge reliability. Its unidirectional configuration and heatsink-anode polarity enable direct integration into high-side clamp circuits with minimal forward voltage drop (VF ≤ 1.8 V at 100 A).
The device delivers 6600 W peak pulse power under 10/1000 μs waveform and sustains 5200 W under 10/10 000 μs waveform - meeting stringent automotive load dump requirements per ISO7637-2 while maintaining clamping integrity up to 175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.4 V / 15.9 V - ensures reliable triggering above system nominal voltage without false conduction |
| VWM | 13.0 V - defines maximum continuous reverse operating voltage before leakage exceeds 10 μA |
| VC @ IPPM | 21.5 V - clamps transients to safe levels for downstream 24 V automotive ICs during 307 A surges |
| PPPM (10/1000 μs) | 6600 W - enables single-event suppression of severe load dump spikes without failure |
| TJ max. | 175 °C - supports placement near hot engine compartments and meets AEC-Q101 automotive qualification |
| RθJC | 0.90 °C/W - allows effective heat transfer to PCB copper or external heatsink for sustained power dissipation |
| IFSM | 700 A - withstands repetitive 8.3 ms half-sine surge currents common in alternator fault conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5AT | Lower PPPM (400 W), SMA package, RθJC ≈ 45 °C/W, VC = 21.5 V at 18.5 A | Not suitable for load dump; limited to ESD and low-energy transients in infotainment or sensor nodes | Select only for cost-sensitive non-automotive applications where surge energy is <5% of SM8S13A-001HE3/2D capability |
| TPSMD13A | Same DO-218AB package, PPPM = 6600 W, but VBR = 14.4–15.9 V and VC = 23.2 V at 284 A - higher clamping voltage | Acceptable for general 12 V protection but less margin for 28 V-rated downstream ICs | Prefer SM8S13A-001HE3/2D when clamping voltage headroom below 22 V is critical for system reliability |
Compared with SMAJ13A-E3/5AT and TPSMD13A, SM8S13A-001HE3/2D delivers superior thermal performance (RθJC = 0.90 °C/W vs. >40 °C/W), full AEC-Q101 qualification, and verified ISO7637-2 compliance - making it the only choice for production automotive load dump protection.

FAQ
What is the clamping voltage of SM8S13A-001HE3/2D at its rated peak pulse current?
The SM8S13A-001HE3/2D has a maximum clamping voltage (VC) of 21.5 V when subjected to its peak pulse current (IPPM) of 307 A under a 10/1000 μs waveform. This value is measured at TC = 25 °C and ensures downstream 24 V-rated components remain within safe operating limits during load dump events. The SM8S13A-001HE3/2D maintains this clamping performance across its full operating temperature range.
Is SM8S13A-001HE3/2D qualified for automotive applications?
Yes, SM8S13A-001HE3/2D is AEC-Q101 qualified and explicitly designed for automotive use. It meets ISO7637-2 load dump requirements, operates up to 175 °C junction temperature, and is manufactured in a TS16949-certified facility. The HE3 suffix confirms RoHS compliance and JESD201 Class 2 whisker resistance - all documented in Vishay's official qualification report for SM8S13A-001HE3/2D.
What does the "/2D" suffix indicate in SM8S13A-001HE3/2D?
The "/2D" suffix in SM8S13A-001HE3/2D specifies the packaging format: 13-inch diameter plastic tape and reel, with 750 units per reel and anode orientation toward the sprocket hole. This is the standard delivery mode for automated SMT placement. The "2D" code is defined in Vishay's ordering information table and applies exclusively to the SM8S13A-001HE3/2D variant.
Can SM8S13A-001HE3/2D replace SM8S13AHE3/2D?
Yes, SM8S13A-001HE3/2D is functionally identical to SM8S13AHE3/2D. The "-001" prefix denotes Vishay's internal revision or manufacturing lot identifier and does not affect electrical specifications, package dimensions, or qualification status. Both part numbers share identical VBR, VWM, VC, PPPM, and AEC-Q101 certification - confirmed in the same datasheet revision (31-Aug-16, Doc. #88387).
What is the thermal resistance from junction to case for SM8S13A-001HE3/2D?
The SM8S13A-001HE3/2D has a typical thermal resistance from junction to case (RθJC) of 0.90 °C/W, measured under standard test conditions. This low value enables efficient heat transfer from the silicon die to the metal heatsink terminal (Lead 2), supporting sustained power dissipation in high-temperature automotive environments. This parameter is validated per JEDEC standards and published in the Thermal Characteristics section of the SM8S13A-001HE3/2D datasheet.
