Product details
Overview
SMAJ6.0HE3/5A from Vishay General Semiconductor is a high-reliability, AEC-Q101-qualified unidirectional transient voltage suppressor (TVS) in DO-214AC (SMA) package, designed for automotive and industrial overvoltage protection. It features 6.0 V stand-off voltage (VWM), 11.4 V clamping voltage (VC) at 35.1 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs waveform), protecting sensitive MOSFETs, ICs, and sensor signal lines against inductive switching transients and ESD.
For engineers reviewing the SMAJ6.0HE3/5A datasheet, SMAJ6.0HE3/5A pinout, SMAJ6.0HE3/5A application, or SMAJ6.0HE3/5A equivalent, this device serves as a robust, RoHS-compliant, high-whisker-resistance (JESD 201 Class 2) TVS diode optimized for automotive-grade board-level surge immunity with validated thermal performance and MSL Level 1 reflow compatibility.
Technical Context
The SMAJ6.0HE3/5A employs a glass-passivated silicon junction to achieve fast response time (<1 ps) and low incremental surge resistance, enabling effective clamping of fast-rising transients such as ISO 7637-2 pulses and IEC 61000-4-5 surges. Its unidirectional polarity-marked by a cathode band-ensures correct orientation in DC-biased protection paths.
Rated for continuous operation from −55 °C to +150 °C junction temperature, it delivers stable clamping performance across automotive thermal environments. The device is mounted on 0.2 × 0.2 inch copper pads per specification, achieving 120 °C/W junction-to-ambient thermal resistance and supporting repetitive surge duty cycles up to 0.01%.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0AHE3/5A | Lower VBR range (6.67–7.37 V) and lower VC (10.3 V at 38.8 A); same package and AEC-Q101 qualification. | Better suited for tighter 5 V rail margins where sub-11 V clamping is critical. | Select SMAJ6.0AHE3/5A when system-level testing confirms improved immunity with lower clamping voltage. |
| SMAJ6.0-E3/5A | Commercial-grade (non-AEC-Q101), identical electrical specs but JESD 201 Class 1A whisker resistance and no automotive qualification. | Appropriate for non-automotive industrial or consumer applications with less stringent reliability requirements. | Choose SMAJ6.0-E3/5A for cost-sensitive designs where automotive qualification is not mandated. |
Compared with SMAJ6.0HE3/5A, SMAJ6.0AHE3/5A offers lower clamping voltage at the expense of slightly reduced breakdown consistency, while SMAJ6.0-E3/5A provides identical surge performance without automotive qualification-enabling trade-offs between reliability assurance, clamping precision, and BOM cost.

FAQ
What is the clamping voltage of SMAJ6.0HE3/5A at its rated peak pulse current?
The SMAJ6.0HE3/5A has a maximum clamping voltage (VC) of 11.4 V at 35.1 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88390 and ensures downstream components see limited overvoltage stress during surge events. The SMAJ6.0HE3/5A maintains this clamping performance across its full operating temperature range of −55 °C to +150 °C.
Is SMAJ6.0HE3/5A qualified for automotive applications?
Yes, SMAJ6.0HE3/5A is AEC-Q101 qualified and designated as high-reliability/automotive grade (HE3 suffix). It meets JESD 201 Class 2 whisker resistance, MSL Level 1 reflow profile (260 °C peak), and operates reliably from −55 °C to +150 °C. These qualifications make SMAJ6.0HE3/5A suitable for engine control units, body electronics, and ADAS sensor modules where long-term field reliability is mandatory.
How does the HE3 suffix differ from the E3 suffix in SMAJ6.0HE3/5A?
The HE3 suffix in SMAJ6.0HE3/5A indicates high-reliability/automotive grade qualification (AEC-Q101), JESD 201 Class 2 whisker resistance, and enhanced process controls versus the commercial-grade E3 suffix. SMAJ6.0HE3/5A undergoes additional screening and lifetime testing to meet automotive requirements, whereas SMAJ6.0-E3/5A carries only JESD 201 Class 1A and no AEC-Q101 validation. Both share identical electrical specs and DO-214AC packaging.
What is the reverse leakage current of SMAJ6.0HE3/5A at its stand-off voltage?
At the 6.0 V stand-off voltage (VWM) and 25 °C, SMAJ6.0HE3/5A exhibits a maximum reverse leakage current (ID) of 800 µA. This value is specified in the Electrical Characteristics table of Vishay document 88390 and remains stable across temperature due to its glass-passivated junction. Low leakage ensures minimal power loss in always-on automotive circuits powered by SMAJ6.0HE3/5A-protected rails.
Can SMAJ6.0HE3/5A be used in bi-directional protection configurations?
No, SMAJ6.0HE3/5A is a unidirectional TVS diode, indicated by its lack of "C" or "CA" suffix and presence of a cathode band marking. For bi-directional applications-such as AC signal lines or floating buses-designers must select a part like SMAJ6.0CAHE3/5A, which has symmetric breakdown in both polarities. Using SMAJ6.0HE3/5A in reverse-biased mode risks permanent junction failure due to lack of reverse conduction capability.
