Product details
Overview
1N6292AHE3/51 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 71.3 V to 78.8 V breakdown voltage range at 1 mA test current, 64.1 V maximum stand-off voltage, 104 V clamping voltage at 14.6 A peak pulse current, and 1500 W peak pulse power dissipation with a 10/1000 µs waveform - deployed in automotive power supply inputs and industrial sensor interface circuits.
For engineers reviewing the 1N6292AHE3/51 datasheet, 1N6292AHE3/51 pinout, 1N6292AHE3/51 application, or 1N6292AHE3/51 equivalent, this part serves as a RoHS-compliant, AEC-Q101-qualified TVS for high-energy transient suppression where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.46), and stable thermal performance up to 175 °C junction temperature are required.
Technical Context
This device operates as a uni-directional avalanche diode with glass-passivated junction, delivering precise voltage clamping during ESD, lightning-induced surges, and inductive switching transients. Its 1500 W peak pulse rating is defined under JEDEC-standard 10/1000 µs waveform with 0.01% duty cycle, and it maintains clamping stability across -55 °C to +175 °C operating junction temperature.
The 1N6292AHE3/51 exhibits 0.057 %/°C temperature coefficient of breakdown voltage, 15.4 °C/W junction-to-lead thermal resistance, and 75 °C/W junction-to-ambient thermal resistance - enabling reliable thermal management on standard PCB layouts without forced cooling in most automotive and industrial applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | Lower PPPM (600 W), smaller SMB package (vs. 1.5KE axial), 75 V VBR min/83.3 V max | Not AEC-Q101 qualified; suited for space-constrained consumer or computing designs | Select when board area is critical and surge energy is ≤600 W; verify thermal derating for continuous ambient >85 °C |
| 1.5KE75A-E3/54 | Identical electrical specs but commercial-grade (non-AEC-Q101), same 1.5KE package, E3 suffix only | Lacks automotive qualification; suitable for industrial/commercial power supplies with lower reliability requirements | Choose for cost-sensitive non-automotive applications where AEC-Q101 is not mandated |
Compared with SMBJ75A and 1.5KE75A-E3/54, the 1N6292AHE3/51 uniquely combines AEC-Q101 qualification, 1500 W surge capability, and axial 1.5KE packaging - making it the only option among the three validated for under-hood automotive deployment with full ISO 7637-2 compliance.

FAQ
What is the breakdown voltage tolerance for 1N6292AHE3/51?
The 1N6292AHE3/51 has a specified breakdown voltage range of 71.3 V minimum to 78.8 V maximum at 1 mA test current, yielding a ±5.2% tolerance about the nominal 75 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports predictable system-level surge margin design without over-engineering downstream components.
Is 1N6292AHE3/51 suitable for bi-directional transient protection?
No, the 1N6292AHE3/51 is strictly a uni-directional TVS diode, indicated by the "A" suffix and presence of a cathode band. For bi-directional protection at equivalent voltage ratings, Vishay offers the 1N6292CAHE3/51 variant. Using the uni-directional 1N6292AHE3/51 on AC or floating lines risks forward conduction and failure during negative transients.
What is the maximum clamping voltage of 1N6292AHE3/51 under surge conditions?
The 1N6292AHE3/51 clamps to a maximum of 104 V at its rated peak pulse current of 14.6 A (10/1000 µs waveform). This value is guaranteed per datasheet Fig. 7 and represents worst-case voltage seen by downstream circuitry during standardized surge testing - critical for verifying that protected ICs remain within absolute maximum ratings.
Does 1N6292AHE3/51 require heatsinking in typical applications?
In most applications, the 1N6292AHE3/51 does not require external heatsinking due to its 15.4 °C/W junction-to-lead thermal resistance and ability to dissipate 6.5 W continuously on an infinite heatsink. However, for repetitive surge events or ambient temperatures above 75 °C, PCB copper pour ≥1 in² connected to both leads is recommended to maintain junction temperature below 175 °C.
How does the HE3 suffix affect the reliability of 1N6292AHE3/51?
The HE3 suffix on 1N6292AHE3/51 indicates RoHS compliance plus AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. This means the device undergoes accelerated stress testing (HTGB, HTRB, TCT) and uses matte tin plating resistant to tin whisker growth - directly enhancing long-term reliability in automotive and industrial deployments where field failure is unacceptable.
