Product details
Overview
1N6289HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in power rails and signal lines. It features a 53.2 V to 58.8 V breakdown voltage range at 1 mA, 47.8 V standoff voltage, 77.0 V clamping voltage at 19.5 A peak pulse current, and 1500 W peak pulse power capability with a 10/1000 µs waveform - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the 1N6289HE3/54 datasheet, 1N6289HE3/54 pinout, 1N6289HE3/54 application, or 1N6289HE3/54 equivalent, key selection criteria include verified clamping performance under 10/1000 µs surge, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), RoHS-compliant matte tin plating, and JESD 201 Class 2 whisker resistance.
Technical Context
This TVS diode operates as a silicon avalanche device with glass passivated junction, delivering bidirectional-capable clamping action only when configured in dual-diode arrangements - the 1N6289HE3/54 itself is unidirectional, with cathode marked by color band. Its 1500 W peak pulse rating is defined per 10/1000 µs waveform at 0.01% duty cycle, and it maintains stable clamping up to 175 °C junction temperature.
Clamping response time is effectively instantaneous (≤1 ns), and incremental surge resistance is minimized via low RθJL (15.4 °C/W) and high IPPM (19.5 A). The device complies with UL 94 V-0 flammability standard and supports soldering at 275 °C for ≤10 s per JESD 22-B106.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR Min/Max | 53.2 V / 58.8 V at 1 mA - defines reliable avalanche initiation threshold for overvoltage detection |
| VWM | 47.8 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 77.0 V at 19.5 A - clamped voltage during 10/1000 µs transient, limiting downstream stress |
| PPPM | 1500 W - peak surge power handling capacity under standardized lightning-surge waveform |
| IFSM | 200 A - non-repetitive forward surge current rating (8.3 ms half-sine), critical for inrush immunity |
| TJ max | +175 °C - enables operation in under-hood automotive and high-temperature industrial environments |
| RθJL | 15.4 °C/W - low junction-to-lead thermal resistance supports high-power pulse dissipation without heatsink |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A-E3/52 | Lower PPPM (600 W), smaller SMB package (RθJA = 110 °C/W), same VBR range (55.1–60.7 V) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or IEC 61000-4-5 Level 4 | Select when board space is constrained and surge threat level is limited to IEC 61000-4-4 EFT only. |
| 1.5KE56AHE3_A | Same electrical specs but HE3_A revision (older AEC-Q101 qualification batch; no Class 2 whisker test) | Acceptable for non-automotive industrial use where whisker risk is mitigated by conformal coating | Choose only if legacy BOM alignment or cost sensitivity outweighs enhanced reliability of HE3/54's Class 2 whisker rating. |
Compared with 1N6289HE3/54, SMBJ58A-E3/52 trades surge robustness for compactness, while 1.5KE56AHE3_A matches core parameters but lacks the latest JESD 201 Class 2 whisker assurance - making 1N6289HE3/54 the preferred choice for automotive and high-reliability industrial deployments.

FAQ
What is the exact breakdown voltage range for the 1N6289HE3/54?
The 1N6289HE3/54 has a guaranteed breakdown voltage (VBR) range of 53.2 V to 58.8 V measured at 1 mA test current (IT). This range is specified per the Vishay datasheet document 88301 and reflects the minimum and maximum values observed across production lots at TA = 25 °C. The 1N6289HE3/54 uses this tight VBR window to ensure consistent clamping onset across automotive and industrial applications.
Is the 1N6289HE3/54 AEC-Q101 qualified and what does the HE3/54 suffix indicate?
Yes, the 1N6289HE3/54 is AEC-Q101 qualified per Vishay documentation. The HE3 suffix denotes RoHS compliance plus AEC-Q101 qualification, while /54 specifies packaging in 13" paper tape and reel with 1400 units per reel. This makes the 1N6289HE3/54 suitable for automotive electronics where both reliability validation and standardized logistics are required.
What is the clamping voltage of the 1N6289HE3/54 under a 10/1000 µs surge?
The 1N6289HE3/54 clamps to a maximum of 77.0 V when subjected to its rated peak pulse current of 19.5 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and represents the upper limit of voltage seen by downstream circuitry during worst-case surge events - a critical parameter for ensuring compatibility with 40 V or 60 V rated components in the protected path.
Can the 1N6289HE3/54 be used in bidirectional configurations?
No, the 1N6289HE3/54 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants in the same family use the "CA" suffix (e.g., 1.5KE56CA). To achieve bidirectional protection with the 1N6289HE3/54, two devices must be connected in series opposing configuration - but this increases footprint and alters clamping behavior versus a native bidirectional part.
What is the thermal resistance from junction to lead (RθJL) for the 1N6289HE3/54?
The 1N6289HE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W, as published in the Vishay datasheet. This low value enables efficient heat transfer from the silicon die to the PCB copper through the leads, supporting high peak power dissipation without external heatsinking - a key advantage over smaller-package alternatives like SMBJ or SMC devices.
