Product details
Overview
1N6292HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power rails and signal lines. It features a 71.3 V to 78.8 V breakdown voltage (VBR) at 1 mA, 64.1 V standoff voltage (VWM), 104 V clamping voltage (VC) at 14.6 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across -55 °C to +175 °C junction temperature - deployed in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1N6292HE3/54 datasheet, 1N6292HE3/54 pinout, 1N6292HE3/54 application, or 1N6292HE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 15.4 °C/W), JEDEC 1.5KE package dimensions, and real-world clamping behavior under transient surge conditions.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its clamping action begins at VBR = 71.3–78.8 V and limits transients to VC = 104 V at IPPM = 14.6 A under standardized 10/1000 µs waveform stress.
Designed for high-reliability environments, the 1N6292HE3/54 meets AEC-Q101 qualification (per note 2 in datasheet), supports 200 A non-repetitive forward surge (IFSM), and maintains stable performance up to TJ = 175 °C with RθJA = 75 °C/W and RθJL = 15.4 °C/W thermal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V at IT = 1 mA - defines precise voltage threshold where clamping initiates |
| VWM | 64.1 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 104 V at 14.6 A - peak clamped voltage during 1500 W transient, limiting downstream stress |
| PPPM | 1500 W (10/1000 µs) - surge energy handling capacity without failure |
| IFSM | 200 A (8.3 ms half-sine) - withstands high-current inductive switch-off events |
| TJ range | -55 °C to +175 °C - enables deployment in under-hood automotive and industrial ambient extremes |
| AEC-Q101 | Qualified - validated for automotive-grade reliability per stress test requirements |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A-E3/52 | Lower PPPM (600 W), smaller SMB package (vs. axial 1.5KE), VC = 121 V @ 4.9 A | Better suited for space-constrained PCBs but requires derating for >1 kV surge events | Select when board area is critical and peak surge energy is ≤600 W |
| 1.5KE75AHE3_A | Same electrical specs and 1.5KE package, but AEC-Q101 qualified only up to revision B (not C/D) | Acceptable for legacy automotive programs where qualification revision level is not enforced | Choose if sourcing flexibility is needed and AEC-Q101 revision compliance is not mandatory |
Compared with 1N6292HE3/54, SMBJ75A-E3/52 trades surge capacity for footprint reduction, while 1.5KE75AHE3_A matches form/fit/function but lacks the latest AEC-Q101 revision validation - making 1N6292HE3/54 the preferred choice for new automotive designs requiring full qualification traceability.

FAQ
What is the breakdown voltage range of the 1N6292HE3/54?
The 1N6292HE3/54 has a guaranteed breakdown voltage (VBR) range of 71.3 V to 78.8 V at a test current of 1 mA, measured per JEDEC standard. This tight tolerance ensures consistent clamping initiation across production lots and supports reliable design margining against downstream IC absolute maximum ratings. The 1N6292HE3/54 achieves this via precision-doped silicon and glass passivation.
Is the 1N6292HE3/54 qualified for automotive applications?
Yes, the 1N6292HE3/54 is AEC-Q101 qualified per datasheet note (2), covering devices from 1.5KE6.8AHE3_B through 1.5KE220AHE3_B and corresponding bidirectional variants. This qualification confirms its suitability for automotive powertrain, chassis, and body electronics where reliability under thermal cycling, humidity, and mechanical shock is mandatory. The 1N6292HE3/54 carries the HE3 suffix indicating AEC-Q101 compliance.
What is the clamping voltage of the 1N6292HE3/54 at its rated peak pulse current?
The 1N6292HE3/54 clamps to a maximum of 104 V at its rated peak pulse current (IPPM) of 14.6 A, tested with a 10/1000 µs waveform. This value reflects worst-case device behavior under standardized surge conditions and directly determines the maximum overvoltage imposed on protected circuitry. The low clamping ratio (VC/VBR ≈ 1.34) makes the 1N6292HE3/54 effective for safeguarding 75 V-rated components.
Does the 1N6292HE3/54 have a unidirectional or bidirectional configuration?
The 1N6292HE3/54 is a unidirectional TVS diode, indicated by the "A" suffix (as opposed to "CA" for bidirectional). Its polarity is marked by a cathode band on the body, and it conducts only during reverse-bias overvoltage events - ideal for DC power rail protection where polarity is fixed. Bidirectional variants like 1N6292HE3/54CA do not exist; the 1N6292HE3/54 is strictly unidirectional per Vishay's 1.5KE family designation.
What package type does the 1N6292HE3/54 use, and what are its key mechanical features?
The 1N6292HE3/54 uses the JEDEC-standardized 1.5KE axial-leaded package: molded epoxy body over passivated junction, UL 94 V-0 rated, with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Lead finish meets JESD 201 Class 2 whisker resistance. Dimensions include 1.0" minimum body length and 0.375" lead length - enabling through-hole mounting and robust mechanical anchoring in high-vibration environments.
