Product details
Overview
1N6286-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 40.9 V to 45.2 V breakdown voltage range (VBR), 36.8 V maximum working peak reverse voltage (VWM), 59.3 V clamping voltage at 25.3 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - used to safeguard MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the 1N6286-E3/54 datasheet, 1N6286-E3/54 pinout, 1N6286-E3/54 application, or 1N6286-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, polarity marking guidance, clamping performance under surge conditions, and direct alternatives for circuit redesign or supply continuity planning.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector, triggering when transient voltage exceeds its VBR threshold and diverting surge current away from downstream components. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 µA at VWM), while the 10/1000 µs waveform rating reflects standardized surge immunity testing per R.E.A. and ANSI/IEEE C62.35.
The device exhibits a temperature coefficient of +0.101 %/°C for VBR, enabling predictable derating above 25 °C ambient, and supports 200 A non-repetitive forward surge current (8.3 ms half-sine). Its thermal resistance (RθJL = 15.4 °C/W) allows effective heat dissipation through PCB copper and lead frames without active cooling.

FAQ
What is the breakdown voltage tolerance for 1N6286-E3/54?
The 1N6286-E3/54 has a specified breakdown voltage range of 40.9 V to 45.2 V at 1.0 mA test current, corresponding to a ±5 % tolerance around the nominal 43 V rating. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margin design in 36 V systems. The value is measured per JEDEC standard and confirmed in Vishay's 88301 datasheet revision 09-Aug-2022.
Does 1N6286-E3/54 support bidirectional transient suppression?
No, 1N6286-E3/54 is a unidirectional TVS diode, intended for DC rail protection where polarity is fixed. Bidirectional variants (e.g., 1N6286CA) exist in the same family but are distinct part numbers. The "A" suffix and absence of "CA" in 1N6286-E3/54 confirm unidirectional operation, with cathode marked by a band. Using it in AC or floating applications without polarity awareness risks failure.
What is the maximum clamping voltage of 1N6286-E3/54 under surge conditions?
The maximum clamping voltage (VC) of 1N6286-E3/54 is 59.3 V at 25.3 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value represents the worst-case voltage seen by downstream components during a full-rated surge event and is critical for verifying that protected ICs remain within absolute maximum ratings. It is measured per ANSI/IEEE C62.35 and published in the Electrical Characteristics table of the 88301 datasheet.
Is 1N6286-E3/54 qualified to AEC-Q101?
No, 1N6286-E3/54 is a commercial-grade part with E3 suffix (RoHS-compliant, JESD 201 Class 1A whisker tested) but not AEC-Q101 qualified. AEC-Q101 versions carry the HE3 suffix (e.g., 1.5KE43AHE3_B). For automotive applications requiring qualification, engineers must select the HE3 variant - 1N6286-E3/54 is appropriate for industrial, telecom, and consumer use where AEC-Q101 is not mandated.
What packaging format does 1N6286-E3/54 ship in?
1N6286-E3/54 ships in 13-inch diameter paper tape and reel packaging, with a base quantity of 1400 units per reel (package code "54"). This format supports automated pick-and-place assembly and is documented in the Ordering Information section of Vishay's 88301 datasheet. The "E3/54" suffix explicitly denotes both RoHS compliance (E3) and this tape-and-reel configuration (54).
