Product details
Overview
1N6290-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 62 V breakdown voltage (VBR = 58.9–65.1 V at 1 mA), 53.0 V standoff voltage (VWM), 85.0 V clamping voltage at 17.6 A peak pulse current, and 1500 W peak pulse power handling with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1N6290-E3/54 datasheet, 1N6290-E3/54 pinout, 1N6290-E3/54 application, or 1N6290-E3/54 equivalent, this part serves as a high-reliability, RoHS-compliant, commercial-grade TVS diode with verified clamping performance, JEDEC-standard 1.5KE package, and documented thermal derating behavior up to 175 °C junction temperature.
Technical Context
The 1N6290-E3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its unidirectional polarity uses a cathode band marking and delivers stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle.
It is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine), exhibits 3.5 V max forward voltage at 100 A, and maintains operation across –55 °C to +175 °C junction temperature range - supporting robust deployment in automotive, industrial, and telecom power supply front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 53.0 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 85.0 V at 17.6 A - clamped voltage during 1500 W transient, limiting stress on downstream components |
| PPPM | 1500 W - peak pulse power rating with 10/1000 µs waveform, enabling protection against severe lightning surges |
| IFSM | 200 A - surge current capability for 8.3 ms half-sine, supporting motor drive and relay coil suppression |
| TJ max | +175 °C - high-temperature junction rating allowing use in under-hood or enclosed industrial environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, informing heatsinking requirements for sustained power dissipation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ64A | Same 64 V VBR range (60.8–67.2 V), identical 1500 W PPPM, but DO-214AC (SMA) surface-mount package | Requires PCB redesign for SMT vs. axial through-hole; better for space-constrained layouts but lacks lead-forming flexibility | Select when board area is constrained and reflow assembly is preferred over wave soldering |
| ON Semiconductor 1.5KE62A | Identical electrical specs (VBR, VC, PPPM) and 1.5KE package; same RoHS/E3 suffix; manufactured to equivalent AEC-Q101-optional spec | No functional or mechanical difference - direct second-source alternative with identical pinout and mounting | Choose for dual-sourcing assurance without layout or test fixture changes |
Compared with 1N6290-E3/54, SMAJ64A offers SMT compatibility at the cost of through-hole replaceability, while 1.5KE62A provides identical form-fit-function as a validated second source - both preserve the 85.0 V clamping ceiling and 175 °C thermal envelope required for harsh-environment reliability.

FAQ
What is the breakdown voltage tolerance of the 1N6290-E3/54?
The 1N6290-E3/54 has a specified breakdown voltage range of 58.9 V to 65.1 V at 1 mA test current, representing ±5% tolerance around the nominal 62 V rating. This tight VBR window ensures consistent triggering behavior across production lots and supports predictable system-level overvoltage margining in designs using the 1N6290-E3/54.
Is the 1N6290-E3/54 suitable for automotive applications?
The 1N6290-E3/54 is a commercial-grade part and not AEC-Q101 qualified; however, its 175 °C maximum junction temperature, 200 A surge rating, and robust 1500 W clamping make it suitable for non-safety-critical automotive subsystems such as infotainment power rails or body control module peripherals - provided full qualification testing is performed per OEM requirements. For certified automotive use, specify the HE3 variant (e.g., 1.5KE62AHE3_B).
What is the maximum clamping voltage of the 1N6290-E3/54 under surge conditions?
The 1N6290-E3/54 clamps to a maximum of 85.0 V when subjected to its rated 17.6 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed across temperature and represents the upper limit of voltage imposed on protected circuitry during worst-case transient events - a key parameter for validating safe operation of downstream 100 V-rated MOSFETs or 75 V-input regulators used with the 1N6290-E3/54.
Does the 1N6290-E3/54 have bidirectional capability?
No, the 1N6290-E3/54 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., 1.5KE62CA). Using the 1N6290-E3/54 in AC or floating applications requires external circuitry to manage polarity; for true bidirectional protection, select a CA-part or series-connected pair.
What packaging format is supplied for the 1N6290-E3/54?
The 1N6290-E3/54 is supplied in 13-inch paper tape and reel packaging with a base quantity of 1400 units per reel (ordering code "/54"). The "E3" suffix confirms RoHS compliance and JESD201 Class 1A whisker resistance, while the axial 1.5KE (DO-201AD) package supports both manual prototyping and automated wave-solder assembly - a key advantage of the 1N6290-E3/54 in mixed-technology production environments.
