Product details
Overview
1N6292-E3/54 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 71.3 V to 78.8 V breakdown voltage (VBR) at 1 mA, 64.1 V maximum standoff voltage (VWM), 104 V clamping voltage (VC) at 14.6 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces against lightning-induced transients and inductive switching surges.
For engineers reviewing the 1N6292-E3/54 datasheet, 1N6292-E3/54 pinout, 1N6292-E3/54 application, or 1N6292-E3/54 equivalent, this part delivers verified transient suppression performance in commercial-grade, through-hole 1.5KE package designs requiring robust ESD and surge immunity per IEC 61000-4-2/4-5 and UL 497B.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VWM (64.1 V), then rapidly avalanches into low-impedance conduction above VBR (min 71.3 V) to divert surge energy away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
It supports single-pulse 1500 W dissipation under 10/1000 µs waveform with <1 ns response time, handles 200 A non-repetitive forward surge (8.3 ms half-sine), and maintains operation across -55 °C to +175 °C junction temperature range - enabling use in automotive power modules and industrial motor drives where thermal reliability is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 71.3 V / 78.8 V at 1 mA - defines precise avalanche onset threshold for predictable clamping initiation |
| VWM | 64.1 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 104 V at 14.6 A - clamping voltage during full 1500 W surge, limiting protected node stress |
| PPPM | 1500 W - peak pulse power handling with 10/1000 µs waveform, suitable for IEC 61000-4-5 Level 4 |
| IFSM | 200 A - surge current rating for 8.3 ms half-sine, supporting inductive load switch-off events |
| Junction Temp | -55 °C to +175 °C - enables deployment in under-hood automotive and high-temp industrial environments |
| Package | 1.5KE case - axial-leaded, epoxy-molded, UL 94 V-0 rated, RoHS-compliant (E3 suffix) |
Pinout & Package
1N6292-E3/54 uses the standard 1.5KE axial-leaded package: matte tin-plated leads, 0.375" (9.5 mm) lead length, 0.210"–0.285" body diameter. Cathode identified by color band on one end; anode is unmarked lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked lead) | Current entry point in forward bias; connected to system ground or low-side return path | Provides reference node for clamping action; must be routed with low-inductance path to ground plane |
| Cathode (banded lead) | Current exit point in forward bias; connected to protected line (e.g., VIN, signal) | Defines clamping polarity - reverse-biased during normal operation, avalanches toward ground during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance (±5 %) and long-term reliability under thermal cycling |
| 1500 W peak pulse power | Supports IEC 61000-4-5 surge immunity up to 4 kV (line-to-earth) without derating |
| <1 ns response time | Clamps transients before sensitive logic or analog circuits experience damaging overvoltage |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising surges (e.g., ESD, relay bounce) |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance and J-STD-002 solderability standards |

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 | Surface-mount SMB package (3.5 × 3.5 mm), same VBR range (71.3–78.8 V), lower PPPM (600 W) | Designed for PCB space-constrained designs; not suitable for high-energy 1500 W surges | Select SMBJ75A only when board layout requires SMT and surge threat level is ≤600 W (e.g., secondary-side protection) |
| 1N6292A | Same electrical specs and 1.5KE package, but non-RoHS (legacy leaded) and no JESD 201 whisker qualification | Permitted only in non-automotive, non-RoHS-regulated legacy systems with existing qualification | Choose 1N6292-E3/54 for new designs requiring RoHS compliance, AEC-Q101 alignment, and traceable sourcing |
Compared with SMBJ75A, 1N6292-E3/54 provides triple the pulse power handling and proven axial-leaded mechanical robustness for high-reliability power entry points; compared with 1N6292A, it adds RoHS compliance, whisker-resistant plating, and documented commercial-grade lifecycle support.

FAQ
What is the clamping voltage of the 1N6292-E3/54 under a 1500 W surge?
The 1N6292-E3/54 clamps to a maximum of 104 V at its rated peak pulse current of 14.6 A, corresponding to the 10/1000 µs waveform that defines its 1500 W rating. This value is measured per JEDEC test conditions and ensures predictable overvoltage limiting during standardized surge events. The 1N6292-E3/54 maintains this clamping performance across its specified operating temperature range.
Is the 1N6292-E3/54 RoHS compliant and qualified for automotive use?
The 1N6292-E3/54 carries the E3 suffix, confirming RoHS compliance and JESD 201 Class 1A whisker resistance. While it is commercial-grade (not AEC-Q101 qualified), its 175 °C max junction temperature, robust construction, and validated surge performance make it widely deployed in automotive power modules where AEC-Q101 is not mandated. For AEC-Q101, the HE3 variant (e.g., 1N6292AHE3_B) is required. The 1N6292-E3/54 itself meets UL 497B recognition.
How does the 1N6292-E3/54 differ from bidirectional TVS diodes like 1N6292CA?
The 1N6292-E3/54 is unidirectional and intended for DC line protection where polarity is fixed - it blocks reverse voltage up to 64.1 V and clamps positive transients to ground. In contrast, 1N6292CA is bidirectional, providing symmetrical clamping for AC lines or floating signals. The 1N6292-E3/54 has a cathode band marking; 1N6292CA has no polarity marking. Their VBR, VC, and PPPM values differ due to internal structure - the 1N6292-E3/54 is not interchangeable with 1N6292CA without circuit redesign.
What is the maximum leakage current of the 1N6292-E3/54 at its standoff voltage?
At its maximum working voltage of 64.1 V (VWM), the 1N6292-E3/54 exhibits a maximum reverse leakage current of 1 µA at 25 °C. This low leakage ensures minimal power loss and signal interference in always-on circuits such as sensor bias rails or standby power monitors. Leakage increases with temperature but remains under 10 µA up to 125 °C, as confirmed in Vishay's thermal derating curves.
Can the 1N6292-E3/54 be used in parallel to increase surge handling capacity?
No - the 1N6292-E3/54 should not be paralleled without external balancing components. Due to VBR tolerance (±5 %), mismatched avalanche onset causes uneven current sharing, risking thermal runaway in one device. For higher pulse power, Vishay recommends using a single higher-rated device (e.g., 1.5KE100A) or verified multi-stage protection topologies. The 1N6292-E3/54 is characterized and qualified as a standalone unit.
