Product details
Overview
1N6292A-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in power rails and signal lines. It features a 71.3 V to 78.8 V breakdown voltage (VBR), 64.1 V standoff voltage (VWM), 104 V clamping voltage at 14.6 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates from −55 °C to +175 °C - used in automotive power supply input stages and industrial sensor interface protection.
For engineers reviewing the 1N6292A-E3/73 datasheet, 1N6292A-E3/73 pinout, 1N6292A-E3/73 application, or 1N6292A-E3/73 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, thermal resistance (RθJA = 75 °C/W), polarity marking convention, and direct alternative part comparisons for ESD and lightning surge protection design.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its clamping behavior is defined by a 10/1000 µs waveform with 0.01% duty cycle, and it supports repetitive surge events under derated conditions above 25 °C ambient per Fig. 2.
The device complies with JEDEC standard 1.5KE case outline, features matte tin-plated leads solderable per J-STD-002, and meets RoHS requirements (E3 suffix). Polarity is marked by a cathode band; no marking applies to bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V - ensures reliable conduction onset above normal operating voltage while avoiding false triggering |
| VWM | 64.1 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 104 V - clamped voltage during 14.6 A transient, limiting downstream component stress |
| PPPM | 1500 W - peak surge power handling capability for 1 ms 10/1000 µs transients |
| IPPM | 14.6 A - maximum non-repetitive peak pulse current the device sustains without failure |
| TJ max. | +175 °C - enables operation in under-hood automotive or high-temperature industrial environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, critical for PCB layout and heatsinking decisions |
Pinout & Package
Package: JEDEC 1.5KE molded epoxy case (Case Style 1.5KE), axial-leaded, RoHS-compliant, commercial grade. Cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |

Use Value: Prevents MOSFET drain-source breakdown by clamping flyback voltage to 104 V, enabling use of 150 V-rated switches. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | DO-214AA package (SMB), 75 V VWM, 100 V VC @ 15.7 A, 600 W PPPM | Lower power rating; suited for space-constrained PCBs where 1500 W is not required | Select when footprint size is critical and surge threat level is ≤IEC 61000-4-5 Level 3 |
| 1.5KE75A | Same electrical specs and 1.5KE package; identical VBR, VWM, VC, PPPM, and thermal characteristics | No functional difference; alternate manufacturer-marked variant of same device | Drop-in replacement with identical mechanical and electrical behavior - verify reel packaging code (E3/73 vs. standard E3) |
Compared with 1N6292A-E3/73, SMBJ75A offers smaller footprint but reduced surge capacity, while 1.5KE75A provides identical performance in the same JEDEC 1.5KE package - making it a true form-fit-function alternative for sourcing continuity.

FAQ
What is the breakdown voltage range of the 1N6292A-E3/73?
The 1N6292A-E3/73 has a specified breakdown voltage (VBR) range of 71.3 V minimum to 78.8 V maximum at 1.0 mA test current. This tight tolerance ensures consistent clamping onset across production lots and supports reliable overvoltage margining in 60–72 V system designs. The value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's 88301 datasheet Rev. 09-Aug-2022.
Is the 1N6292A-E3/73 unidirectional or bidirectional?
The 1N6292A-E3/73 is a unidirectional TVS diode. Its polarity is marked by a cathode band on the epoxy body, and it conducts only during reverse-biased overvoltage events. Bidirectional versions in the same family carry a "CA" suffix (e.g., 1N6292CA), which the 1N6292A-E3/73 does not include - confirming its unidirectional functionality per Vishay's ordering nomenclature and datasheet Table on page 2.
What package type does the 1N6292A-E3/73 use?
The 1N6292A-E3/73 uses the JEDEC-standard 1.5KE axial-leaded package (Case Style 1.5KE), with molded epoxy body, glass-passivated junction, and matte tin-plated leads. Dimensions are documented in the datasheet Figure on page 5: 0.375" (9.5 mm) lead length, 0.210" (5.3 mm) body diameter. The "E3/73" suffix denotes RoHS-compliant commercial-grade packaging in 73" tape-and-reel format (1400 units per reel).
Does the 1N6292A-E3/73 meet AEC-Q101 qualification?
No, the 1N6292A-E3/73 is not AEC-Q101 qualified. Per Vishay's datasheet Note (2) on page 3, AEC-Q101 qualification applies only to parts with "HE3" suffix (e.g., 1.5KE75AHE3_B). The "E3" suffix indicates RoHS-compliant commercial grade only. For automotive applications requiring AEC-Q101, engineers should select 1.5KE75AHE3_B or equivalent qualified variants instead of the 1N6292A-E3/73.
What is the clamping voltage of the 1N6292A-E3/73 at its rated peak pulse current?
The 1N6292A-E3/73 clamps to a maximum of 104 V at its rated peak pulse current (IPPM) of 14.6 A, measured using the standard 10/1000 µs waveform. This value is specified in the Electrical Characteristics table (page 2 of datasheet 88301) and defines the upper voltage limit imposed on protected circuitry during worst-case surge events - critical for ensuring downstream components remain within their absolute maximum ratings.
