Product details
Overview
1N6286HE3/54 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 43 V breakdown voltage (VBR = 40.9–45.2 V at 1.0 mA), 36.8 V maximum standoff voltage (VWM), 59.3 V clamping voltage (VC) at 25.3 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across –55 °C to +175 °C junction temperature range - deployed in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1N6286HE3/54 datasheet, 1N6286HE3/54 pinout, 1N6286HE3/54 application, or 1N6286HE3/54 equivalent, this part delivers verified bidirectional-capable TVS performance with AEC-Q101 qualification, RoHS-compliant matte tin leads, JESD 201 Class 2 whisker resistance, and UL 94 V-0 molded epoxy packaging - critical for ESD and lightning surge hardening in safety-critical embedded systems.
Technical Context
This device implements a glass-passivated silicon junction optimized for sub-nanosecond response (<1 ns) clamping under transient stress. Its unidirectional polarity uses a cathode band marking and exhibits low incremental surge resistance, enabling precise voltage limiting during 10/1000 µs surges up to 25.3 A without thermal runaway.
Thermal design is supported by RθJA = 75 °C/W and RθJL = 15.4 °C/W, allowing reliable operation at TJ = 175 °C with appropriate PCB copper area or lead heatsinking. The 6.5 W steady-state power dissipation (at TL = 75 °C) and 200 A IFSM rating support robust handling of repetitive inductive switching events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 40.9 V / 45.2 V at 1.0 mA - defines precise clamping onset threshold for overvoltage detection |
| VWM | 36.8 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 59.3 V at 25.3 A - limits worst-case transient voltage seen by downstream ICs |
| PPPM | 1500 W (10/1000 µs) - sustains high-energy surges common in automotive load-dump and inductive kick scenarios |
| TJ Range | –55 °C to +175 °C - enables deployment in engine control units and industrial motor drives |
| IFSM | 200 A (8.3 ms half-sine) - withstands single-event high-current transients without bond-wire fusing |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package with 0.375" lead length, UL 94 V-0 compliant |
Pinout & Package
1N6286HE3/54 uses the standard DO-201AD (Case Style 1.5KE) axial-leaded package with cathode indicated by a color band on one end. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, rated for 275 °C dip soldering (10 s max).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Glass-passivated junction | Enables stable VBR tolerance (±5 %) and long-term reliability under humidity and thermal cycling |
| AEC-Q101 qualified | Validated for automotive-grade operation including temperature cycling, HTRB, and ESD testing per JEDEC standards |
| 1500 W peak pulse power | Handles ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-5 Combination Wave surges without degradation |
| JESD 201 Class 2 whisker resistance | Prevents tin whisker growth under high-humidity, high-temperature storage - critical for long-life automotive modules |
| UL 94 V-0 molding compound | Self-extinguishing epoxy prevents flame propagation in fault conditions within enclosed enclosures |
Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Clamping |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs from load-dump transients (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges above 36.8 V. Use Value: Limits peak voltage to ≤59.3 V during 25.3 A transients, preventing damage to LDOs, microcontrollers, and CAN transceivers. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and cable-induced surges in factory automation. IC Role / Device Role / Timing Role: TVS mounted at connector entry point, anode to signal ground, cathode to sensor output line. Use Value: Sub-1 ns response ensures clamping occurs before sensitive ADC input stages experience overstress beyond absolute maximum ratings. |
| Telecom DC Power Feeds | Consumer Device USB Port Surge Suppression |
Use Scenario: Safeguarding PoE-powered equipment (e.g., IP cameras) against induced lightning surges on outdoor Ethernet cables. IC Role / Device Role / Timing Role: Unidirectional TVS on DC input side of PD controller, referenced to local ground plane. Use Value: 1500 W rating absorbs 10/1000 µs surges up to 25.3 A while maintaining VC below 60 V - preserving IEEE 802.3af/at compliance margins. |
Use Scenario: Adding secondary-level surge protection on VBUS line of USB-C ports in portable electronics. IC Role / Device Role / Timing Role: TVS placed upstream of USB power switch, cathode to VBUS, anode to system ground. Use Value: 36.8 V VWM allows normal 5 V operation with margin; 59.3 V VC prevents overvoltage damage to USB controller and Type-C CC logic. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ43A-E3/52 (Vishay) | DO-214AA (SMB) package; same VBR/VC specs but 600 W PPPM; lower IPPM (12.3 A) | Surface-mount alternative for space-constrained PCBs; not suitable for high-energy load-dump events | Select when board real estate is limited and surge energy does not exceed 600 W; verify thermal relief for SMB footprint. |
| 1.5KE43AHE3/54 (Vishay) | Identical electrical specs and AEC-Q101 qualification; same DO-201AD package; differs only in part numbering convention | No functional or application difference - direct cross-reference per Vishay documentation | Use interchangeably where procurement or legacy BOM references the 1.5KE prefix; identical form, fit, and function. |
Compared with SMBJ43A-E3/52, 1N6286HE3/54 delivers 2.5× higher surge energy handling and axial-leaded through-hole mounting for mechanical robustness; versus 1.5KE43AHE3/54, it is electrically and physically identical - differing only in JEDEC vs. manufacturer-specific part numbering.

FAQ
What is the breakdown voltage tolerance for 1N6286HE3/54?
The 1N6286HE3/54 has a specified breakdown voltage range of 40.9 V to 45.2 V at 1.0 mA test current, representing a ±5 % tolerance around the nominal 43 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports predictable overvoltage protection design in safety-critical circuits.
Is 1N6286HE3/54 qualified for automotive use?
Yes, 1N6286HE3/54 carries AEC-Q101 qualification per Vishay documentation, covering stress tests including high-temperature reverse bias, temperature cycling, and ESD. Its HE3 suffix confirms JESD 201 Class 2 whisker resistance and RoHS compliance - making it suitable for under-hood and chassis-mounted automotive modules.
What is the maximum clamping voltage of 1N6286HE3/54 under surge conditions?
The 1N6286HE3/54 clamps to a maximum of 59.3 V at its rated peak pulse current of 25.3 A (10/1000 µs waveform). This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Can 1N6286HE3/54 be used in bidirectional configurations?
No, 1N6286HE3/54 is a unidirectional TVS diode, identified by its "A" suffix and cathode band marking. Bidirectional variants in the same family use the "CA" suffix (e.g., 1N6286CA). Using 1N6286HE3/54 in bidirectional applications would result in forward conduction during negative transients, causing failure or incorrect protection behavior.
What packaging format does 1N6286HE3/54 ship in?
1N6286HE3/54 ships in 13-inch diameter paper tape and reel packaging with a base quantity of 1400 units per reel (ordering code /54). The device uses axial-leaded DO-201AD (Case Style 1.5KE) construction with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
