Product details
Overview
1N6290HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in the 1.5KE family, designed for robust overvoltage protection of sensitive electronics. It features a breakdown voltage range of 58.9 V to 65.1 V at 1.0 mA test current, clamps transients to ≤85.0 V at 17.6 A peak pulse current, and delivers 1500 W peak pulse power with a 10/1000 µs waveform - used in automotive power line and industrial sensor interface protection.
For engineers reviewing the 1N6290HE3/54 datasheet, 1N6290HE3/54 pinout, 1N6290HE3/54 application, or 1N6290HE3/54 equivalent, key selection criteria include its 53.0 V stand-off voltage, 1.0 µA max reverse leakage at VWM, AEC-Q101 qualification (HE3 suffix), RoHS-compliant matte tin leads, and JEDEC-standard 1.5KE case package with cathode band marking.
Technical Context
This device operates as a silicon avalanche diode optimized for fast clamping of high-energy transients induced by inductive switching or lightning surges. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, while the unidirectional polarity enables integration into DC-biased circuits without reverse conduction concerns.
The 1N6290HE3/54 is rated for 175 °C maximum junction temperature and exhibits a temperature coefficient of +0.104 %/°C for VBR, enabling predictable voltage drift across automotive-grade thermal ranges. Its 75 °C/W junction-to-ambient thermal resistance supports reliable operation under pulsed conditions when mounted on standard PCB copper land patterns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1.0 mA - defines guaranteed avalanche initiation window for precise overvoltage thresholding |
| VWM | 53.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| IPPM | 17.6 A (10/1000 µs) - peak transient current it safely clamps without failure |
| VC | ≤85.0 V at IPPM - clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 1500 W - peak pulse power handling capability, critical for lightning and ESD immunity compliance |
| TJ max | +175 °C - enables use in under-hood automotive environments and high-temperature industrial enclosures |
| Leakage (ID) | ≤1.0 µA at VWM - ensures minimal standby power loss and signal integrity in always-on systems |
Pinout & Package
Package: JEDEC-standard 1.5KE molded epoxy case (Case Style 1.5KE), axial leaded, RoHS-compliant matte tin plating, cathode indicated by color band. Dimensions: 0.375" (9.5 mm) lead length, 0.210"–0.285" body diameter.

| Fast response time (~1 ns) | Clamps transients before downstream ICs experience damaging overvoltage - faster than MOVs or GDTs |
| Low incremental surge resistance | Minimizes voltage overshoot during high-di/dt events, improving protection margin for MOSFET gate drivers |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting 12 V/24 V/48 V battery-fed ECUs from load dump and alternator transients per ISO 16750-2.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A-E3/52 | Lower peak power (600 W), smaller SMB package (vs. axial 1.5KE), VBR = 71.1–78.6 V | Better suited for space-constrained PCBs; less robust for high-energy automotive load dump | Select when board area is critical and surge energy is ≤600 W; verify thermal derating for repeated pulses |
| 1.5KE62AHE3/54 | Same 1.5KE package, identical electrical specs (VBR, VC, PPPM), alternate part numbering convention | No functional difference - dual-marking variant used interchangeably in Vishay's production and logistics | Direct form-fit-function replacement; same AEC-Q101 qualification, same RoHS and whisker test compliance |
Compared with 1N6290HE3/54, SMBJ64A-E3/52 trades peak power and thermal mass for compactness, while 1.5KE62AHE3/54 offers identical performance in an alternative manufacturer-part-number format - enabling supply chain flexibility without design change.

FAQ
What is the breakdown voltage tolerance of the 1N6290HE3/54?
The 1N6290HE3/54 has a specified breakdown voltage range of 58.9 V to 65.1 V at 1.0 mA test current, representing ±5.2% tolerance around the nominal 62 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports reliable overvoltage threshold design in safety-critical systems.
Is the 1N6290HE3/54 AEC-Q101 qualified?
Yes, the 1N6290HE3/54 is AEC-Q101 qualified, as confirmed by the HE3 suffix per Vishay documentation. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for automotive powertrain and chassis applications.
What does the "/54" in 1N6290HE3/54 indicate?
The "/54" denotes the preferred packaging code: 13-inch diameter paper tape and reel containing 1400 units. This format is optimized for automated SMT placement equipment and aligns with industry-standard EIA-481 specifications for axial-leaded components.
How does the 1N6290HE3/54 compare to bidirectional TVS diodes?
The 1N6290HE3/54 is unidirectional and intended for DC-biased lines where only positive-going transients require suppression. Unlike bidirectional variants (e.g., 1N6290CA), it blocks reverse voltage up to 53.0 V but conducts forward surges to ground - making it ideal for 24 V or 48 V supply rails with defined polarity.
What is the maximum clamping voltage of the 1N6290HE3/54 under surge conditions?
The 1N6290HE3/54 clamps to a maximum of 85.0 V when subjected to its rated 17.6 A peak pulse current (10/1000 µs waveform). This clamping voltage is measured across the device terminals and represents the upper limit of voltage imposed on the protected circuit during worst-case transient events.
