Product details
Overview
1N6290A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 62 V breakdown voltage (VBR = 58.9–65.1 V at 1.0 mA), 1500 W peak pulse power (10/1000 µs), clamping voltage of 85.0 V at 17.6 A, and operates across –55 °C to +175 °C. It is used to protect MOSFETs, ICs, and sensor interfaces against inductive switching transients and lightning-induced surges in industrial and automotive systems.
For engineers reviewing the 1N6290A-E3/54 datasheet, 1N6290A-E3/54 pinout, 1N6290A-E3/54 application, or 1N6290A-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under standardized surge waveforms, thermal derating behavior, and validated alternative parts for circuit protection design.
Technical Context
This device implements a glass-passivated silicon junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its unidirectional polarity uses a cathode band marking and exhibits a maximum reverse leakage current of 1.0 µA at 53.0 V stand-off voltage (VWM).
The 1N6290A-E3/54 delivers 1500 W peak pulse power with a 10/1000 µs waveform at 0.01% duty cycle, supported by a thermal resistance of 15.4 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient). Its forward voltage is 3.5 V at 100 A, confirming suitability for high-current surge suppression without forward conduction degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ64A | DO-214AC package (SMA), 64 V VBR, 400 W PPPM, higher RθJA (110 °C/W) | Lower power rating limits use to sub-100 A surge scenarios; surface-mount only | Select when board space constraints require SMD layout and surge energy is ≤400 W |
| ON Semiconductor 1.5KE62A | Identical 1.5KE package, same VBR/VC specs, but non-RoHS E3 variant not available; HE3 version requires AEC-Q101 qualification | Same mechanical fit and electrical performance; differs in material compliance and qualification status | Choose for automotive programs requiring AEC-Q101 documentation; otherwise functionally interchangeable |
Compared with 1N6290A-E3/54, SMAJ64A offers smaller footprint but sacrifices 73% peak power handling and thermal performance, while 1.5KE62A matches all key parameters but lacks RoHS-compliant E3 commercial-grade sourcing-making 1N6290A-E3/54 optimal for cost-sensitive, high-energy industrial designs needing guaranteed lead-free compliance.

FAQ
What is the breakdown voltage tolerance of the 1N6290A-E3/54?
The 1N6290A-E3/54 has a specified breakdown voltage range of 58.9 V to 65.1 V at 1.0 mA test current, yielding ±5.2% tolerance. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes, critical for protecting 60 V-rated power stages without premature conduction.
Does the 1N6290A-E3/54 meet automotive qualification standards?
The 1N6290A-E3/54 is RoHS-compliant and commercial-grade; it is not AEC-Q101 qualified. For automotive applications requiring qualification, Vishay offers the 1.5KE62AHE3_B variant. The 1N6290A-E3/54 remains suitable for non-safety-critical automotive subsystems where full AEC-Q101 documentation is not mandated.
How does the 1N6290A-E3/54 compare to bidirectional TVS diodes like 1N6290CA?
The 1N6290A-E3/54 is unidirectional and features a cathode band; 1N6290CA is bidirectional with no polarity marking and symmetric clamping in both directions. Use 1N6290A-E3/54 for DC line protection where polarity is fixed; choose 1N6290CA only for AC-coupled or floating signal paths requiring dual-polarity suppression.
What is the maximum allowable lead temperature during soldering for the 1N6290A-E3/54?
The 1N6290A-E3/54 supports solder dip at 275 °C maximum for 10 seconds per JESD 22-B106. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for reliable wetting. Exceeding these conditions risks epoxy cracking or junction degradation, compromising surge endurance.
Can the 1N6290A-E3/54 be used in parallel to increase surge current handling?
Yes-the 1N6290A-E3/54 may be paralleled to distribute surge current, but matching VBR within ±2% and using symmetrical PCB layout (equal trace inductance/resistance) is essential. Without balancing, one device may absorb >80% of IPPM, leading to thermal runaway and failure.
