Product details
Overview
1N6290-E3/73 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 stand-off voltage (VWM), 85.0 V clamping voltage (VC) at 17.6 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates from –55 °C to +175 °C junction temperature - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the 1N6290-E3/73 datasheet, 1N6290-E3/73 pinout, 1N6290-E3/73 application, or 1N6290-E3/73 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, polarity marking guidance, clamping performance under surge conditions, and direct alternatives with documented parameter differences.
Technical Context
The 1N6290-E3/73 implements a glass-passivated silicon PN junction optimized for fast transient suppression. Its unidirectional architecture provides cathode-marked polarity, enabling asymmetric clamping on positive-going surges while blocking reverse leakage below 53.0 V. The device sustains 200 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits low incremental surge resistance to minimize voltage overshoot during ESD or lightning-induced transients.
Thermal design relies on its 15.4 °C/W junction-to-lead thermal resistance and 75 °C/W junction-to-ambient rating. It complies with JESD 22-B106 soldering (275 °C, 10 s) and JESD 201 Class 1A whisker testing, confirming suitability for automated assembly in commercial-grade applications without AEC-Q101 qualification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | DO-214AA package (SMB), 64 V VBR, 1000 W PPPM, 13.4 A IPPM, 103 V VC | Lower power rating; surface-mount only; higher clamping voltage reduces margin for 60 V-rated ICs | Select when board space constraints require SMD mounting and 1000 W surge capacity suffices |
| 1.5KE62A | Same 1.5KE package, identical VBR/VWM/VC specs, but E3/54 tape-and-reel packaging instead of E3/73 | No functional difference; differs only in packaging format (reel quantity and orientation) | Direct form-fit-function replacement when sourcing from alternate reel configurations |
Compared with 1N6290-E3/73, SMBJ64A offers compact SMD integration but sacrifices 33 % peak power and increases clamping voltage by 18 V - critical for 60 V system margins; 1.5KE62A matches all electrical and mechanical specs exactly, differing only in packaging logistics.

FAQ
What is the breakdown voltage range of the 1N6290-E3/73?
The 1N6290-E3/73 has a specified breakdown voltage (VBR) range of 58.9 V to 65.1 V at a test current of 1.0 mA. This range reflects manufacturing tolerance and ensures consistent clamping behavior across units. The value is measured per JEDEC standards and directly impacts the device's ability to activate reliably during overvoltage events without premature conduction under normal operating conditions. All 1N6290-E3/73 units meet this specification at 25 °C ambient.
Is the 1N6290-E3/73 RoHS compliant and qualified for automotive use?
The 1N6290-E3/73 carries the E3 suffix, confirming RoHS compliance and JESD 201 Class 1A whisker resistance, but it is not AEC-Q101 qualified. Vishay designates AEC-Q101 versions with the HE3 suffix (e.g., 1.5KE62AHE3_B). Therefore, 1N6290-E3/73 is approved for commercial and industrial applications, not automotive safety-critical systems. For automotive deployment, engineers must select the HE3 variant or verify qualification status via Vishay's official documentation for the exact part number.
What does the "/73" suffix indicate in 1N6290-E3/73?
The "/73" suffix in 1N6290-E3/73 denotes the preferred packaging configuration: 750 pieces per 13-inch diameter paper tape and reel. This differs from other variants like "/54", which specifies 1400 units per reel. The "/73" format aligns with common logistics requirements for medium-volume SMT assembly lines and ensures compatibility with standard pick-and-place feeders. The core electrical and mechanical specifications of the 1N6290-E3/73 remain identical regardless of reel suffix.
How does the clamping voltage of the 1N6290-E3/73 compare to its breakdown voltage?
The 1N6290-E3/73 clamps at 85.0 V when subjected to its rated 17.6 A peak pulse current (10/1000 µs waveform), whereas its breakdown voltage starts at 58.9 V. This 26.1 V differential - known as incremental clamping voltage - reflects the device's dynamic resistance under surge conditions. A lower ΔVC indicates better protection margin; for the 1N6290-E3/73, this value ensures downstream 60 V-rated components remain within safe operating limits during transient events.
Can the 1N6290-E3/73 be used in bidirectional configurations?
No, the 1N6290-E3/73 is strictly a unidirectional TVS diode, as confirmed by its part numbering (no "CA" suffix) and datasheet designation. Bidirectional variants in the same family carry the "CA" suffix (e.g., 1.5KE62CA). Using the 1N6290-E3/73 in reverse-biased AC applications would result in forward conduction and failure. For bidirectional protection, engineers must select a designated CA-series part or implement back-to-back unidirectional devices - neither of which applies to the 1N6290-E3/73.
