Product details
Overview
1N6286A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in power rails and signal lines. It features a 40.9 V to 45.2 V breakdown voltage range at 1 mA test current, 36.8 V maximum standoff voltage, 59.3 V clamping voltage at 25.3 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power supply inputs, industrial PLC I/O modules, and telecom DC feed protection.
For engineers reviewing the 1N6286A-E3/54 datasheet, 1N6286A-E3/54 pinout, 1N6286A-E3/54 application, or 1N6286A-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under surge conditions, thermal derating behavior, and direct alternative options for circuit-level ESD and lightning transient suppression.
Technical Context
This unidirectional TVS diode operates as a fast-acting shunt clamp, activating within <1 ns when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling precise voltage limiting during 8/20 µs or 10/1000 µs surges.
Designed for single-polarity DC protection, it exhibits 3.5 V forward voltage at 100 A surge and supports 200 A non-repetitive peak forward surge current. Thermal resistance is rated at 15.4 °C/W (junction-to-lead), supporting reliable operation up to 175 °C junction temperature with appropriate PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 40.9 V min / 45.2 V max at 1 mA - defines precise clamping onset threshold for overvoltage events |
| Standoff Voltage VWM | 36.8 V max - ensures no conduction during normal 36 V nominal rail operation |
| Clamping Voltage VC | 59.3 V at 25.3 A IPPM - limits transient voltage seen by downstream ICs to safe level |
| Peak Pulse Power PPPM | 1500 W (10/1000 µs) - sustains high-energy transients without failure in industrial surge environments |
| Peak Pulse Current IPPM | 25.3 A (10/1000 µs) - quantifies maximum surge current the device safely diverts to ground |
| Junction Temperature Range | -55 °C to +175 °C - enables deployment in under-hood automotive and high-temp industrial enclosures |
| Leakage Current ID | 1.0 µA max at VWM - minimizes standby power loss in battery-backed systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | DO-214AA package; lower 600 W PPPM; 36 V VBR (34.2–37.8 V); 58.1 V VC at 10.3 A | Better suited for space-constrained PCBs; lower surge handling limits use to Level 3 IEC 61000-4-5 | Select when board area is critical and surge threat level is moderate (e.g., indoor consumer electronics) |
| 1.5KE43A | Same 1.5KE package and electrical specs; identical VBR, VWM, VC, and PPPM - direct form-fit-function replacement | No functional difference; differs only in ordering code (E3/54 vs. standard bulk packaging) | Choose for identical performance with alternate tape-and-reel delivery (1400 pcs/reel, 13″ diameter) |
Compared with 1N6286A-E3/54, SMBJ36A offers smaller footprint but reduced surge capacity, while 1.5KE43A provides identical protection performance in alternate packaging - enabling flexibility in procurement and layout reuse without design change.

FAQ
What is the breakdown voltage tolerance for 1N6286A-E3/54?
The 1N6286A-E3/54 has a specified breakdown voltage range of 40.9 V minimum to 45.2 V maximum at 1 mA test current, corresponding to a ±5% tolerance about the nominal 43 V rating. This tight VBR distribution ensures predictable clamping onset across production lots and supports reliable overvoltage margining in safety-critical designs.
Is 1N6286A-E3/54 suitable for bidirectional transient protection?
No, 1N6286A-E3/54 is a unidirectional TVS diode and must be used with polarity awareness - cathode connected to ground, anode to the protected line. For bidirectional protection, Vishay offers the 1N6286CA variant (with CA suffix), which clamps symmetrically in both directions and has no polarity marking.
What is the maximum allowable junction temperature for 1N6286A-E3/54?
The 1N6286A-E3/54 has a maximum junction temperature (TJ) rating of +175 °C, validated per JEDEC standards. Derating begins above 25 °C ambient, with power dissipation reduced linearly to zero at 175 °C - enabling operation in engine bay or industrial enclosure environments when mounted on adequate copper area.
How does the clamping voltage of 1N6286A-E3/54 compare to its standoff voltage?
The 1N6286A-E3/54 has a maximum standoff voltage (VWM) of 36.8 V and a clamping voltage (VC) of 59.3 V at 25.3 A - yielding a 22.5 V clamping margin. This differential ensures no conduction during normal operation while guaranteeing effective voltage limiting during transients, critical for protecting 40 V-rated downstream components.
What packaging format does 1N6286A-E3/54 ship in?
The 1N6286A-E3/54 ships in 13″ diameter paper tape and reel packaging, with a base quantity of 1400 pieces per reel (package code "54"). The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance, making it suitable for lead-free reflow assembly processes.
