Product details
Overview
SM8S13A-001HE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor in DO-218AB package, rated for 13.0 V stand-off voltage (VWM), 15.2 V nominal breakdown (VBR), and 6600 W peak pulse power (10/1000 μs). It delivers AEC-Q101 qualification, 175 °C junction temperature capability, and low leakage (<10 μA at VWM), making it suitable for automotive load dump protection in engine control units and body electronics.
For engineers reviewing the SM8S13A-001HE3_A/I datasheet, SM8S13A-001HE3_A/I pinout, SM8S13A-001HE3_A/I application, or SM8S13A-001HE3_A/I equivalent, key selection criteria include its unidirectional polarity, DO-218AB thermal performance (RθJM = 0.35 °C/W), clamping voltage of 21.5 V at 307 A, and compliance with ISO7637-2 surge testing under automotive conditions.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and low forward voltage drop (≤1.8 V at 100 A). Its junction design supports reliable operation up to TJ = 175 °C and meets MSL Level 1 reflow requirements (245 °C peak).
The device operates exclusively in unidirectional mode with heatsink as anode, enabling robust clamping during positive transients. Its 6600 W peak pulse power rating (10/1000 μs) and 5200 W rating (10/10 000 μs) are validated per standardized waveforms, and it exhibits a VBR temperature coefficient of +0.076 %/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.0 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (nom) | 15.2 V at 5 mA - precise breakdown threshold ensuring predictable turn-on during overvoltage events |
| VC @ IPPM | 21.5 V at 307 A - clamping voltage limiting downstream circuit stress during 10/1000 μs surges |
| PPPM (10/1000 μs) | 6600 W - peak transient energy absorption capacity critical for automotive load dump immunity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SM8S13AHM3_A/I | Same electrical specs but HM3 suffix indicates enhanced material categorization and updated AEC-Q101 test reporting per revision 2025 | Preferred for new designs targeting latest automotive qualification documentation requirements | Select SM8S13AHM3_A/I when full traceability to current AEC-Q101 revision and RoHS/REACH compliance documentation is mandatory |
| SMAJ13A-E3/5AT | Lower PPPM (400 W vs. 6600 W), DO-214AC package, RθJA ≈ 40 °C/W, no AEC-Q101 qualification | Limited to non-automotive, low-energy industrial I/O protection where surge levels are below 100 A | Choose SMAJ13A-E3/5AT only for cost-sensitive consumer or industrial applications with verified sub-100 A transient exposure |
Compared with SM8S13A-001HE3_A/I, SM8S13AHM3_A/I offers identical clamping and thermal performance with updated compliance reporting, while SMAJ13A-E3/5AT provides basic protection at lower cost but lacks automotive qualification and cannot handle load dump energy.

FAQ
What is the maximum clamping voltage of the SM8S13A-001HE3_A/I at its rated peak pulse current?
The SM8S13A-001HE3_A/I has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current of 307 A under a 10/1000 μs waveform. This value is measured per standard test conditions and ensures downstream components experience controlled overvoltage stress during surge events. The SM8S13A-001HE3_A/I maintains this clamping performance across its full operating temperature range.
Is the SM8S13A-001HE3_A/I suitable for new automotive designs despite the "Not For New Designs" note in the datasheet?
The "Not For New Designs" notice applies to the entire SM8S10A–SM8S43A series and directs designers toward the newer SM8SxxAHM3 variants. However, SM8S13A-001HE3_A/I remains fully qualified, in active production, and supported for legacy program continuity and existing design refreshes. The SM8S13A-001HE3_A/I retains full AEC-Q101 qualification and ISO7637-2 compliance.
How does the DO-218AB package of the SM8S13A-001HE3_A/I improve thermal performance compared to DO-214AB?
The DO-218AB package of the SM8S13A-001HE3_A/I features an integrated metal heatsink terminal (anode) that reduces junction-to-mount thermal resistance to 0.35 °C/W-over 5× better than typical DO-214AB packages. This allows the SM8S13A-001HE3_A/I to sustain higher surge energy without thermal runaway, especially critical in confined under-hood layouts where airflow is limited.
Does the SM8S13A-001HE3_A/I meet ISO7637-2 Pulse 5a requirements out of the box?
Yes-the SM8S13A-001HE3_A/I is explicitly characterized to meet ISO7637-2 Pulse 5a (load dump) requirements under defined test conditions, including 35 V/100 ms waveform with appropriate coupling network. Its 6600 W peak pulse power rating and 21.5 V clamping voltage ensure compliance when mounted per recommended PCB layout guidelines. The SM8S13A-001HE3_A/I datasheet confirms this validation.
What is the leakage current specification for the SM8S13A-001HE3_A/I at maximum operating temperature?
At TJ = 175 °C and VWM = 13.0 V, the SM8S13A-001HE3_A/I exhibits a maximum reverse leakage current of 10 μA. This elevated-temperature leakage value is confirmed in the Electrical Characteristics table and ensures minimal parasitic loading on always-on vehicle circuits-even in extreme under-hood thermal environments. The SM8S13A-001HE3_A/I maintains this performance across its full -55 °C to +175 °C operating range.
