Product details
Overview
1N6284A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-side overvoltage protection in DC power rails and signal lines. It features a 34.2 V to 37.8 V breakdown voltage (VBR) at 1 mA, 30.8 V maximum standoff voltage (VWM), 49.9 V clamping voltage (VC) at 30.1 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 1N6284A-E3/54 datasheet, 1N6284A-E3/54 pinout, 1N6284A-E3/54 application, or 1N6284A-E3/54 equivalent, this part delivers verified transient suppression performance for 24–36 V system rails, meets JEDEC 1.5KE package mechanical standards, supports RoHS-compliant automated assembly via E3 matte tin plating, and provides documented thermal resistance (RθJA = 75 °C/W) for board-level thermal design validation.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR, it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM), while the 10/1000 µs waveform rating reflects standardized lightning-surge immunity testing per IEC 61000-4-5.
The device exhibits 0.099 %/°C temperature coefficient of VBR, enabling predictable clamping behavior across –55 °C to +175 °C operating junction range. With 200 A non-repetitive forward surge capability (8.3 ms half-sine) and 6.5 W steady-state power dissipation on infinite heatsink, it supports both transient event handling and limited continuous power dissipation in compact PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V at 1.0 mA - defines precise avalanche onset threshold for reliable triggering in 30–36 V nominal systems |
| VWM | 30.8 V - maximum continuous reverse working voltage before leakage exceeds 1 µA; sets safe DC rail margin |
| VC @ IPPM | 49.9 V at 30.1 A - clamping voltage during 1500 W transient; determines protected circuit's peak stress level |
| PPPM | 1500 W - peak pulse power handling with 10/1000 µs waveform; qualifies for Level 4 IEC 61000-4-5 surge immunity |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance; enables thermal derating calculation for PCB copper area |
| TJ max. | +175 °C - maximum junction temperature; supports operation in high-ambient industrial environments |
| Package | Case Style 1.5KE - axial-leaded DO-201AD package (0.375" lead length); compatible with through-hole reflow and wave soldering |
Pinout & Package
1N6284A-E3/54 uses the standard DO-201AD (Case Style 1.5KE) axial-leaded package with cathode indicated by a color band. Leads are matte tin plated per J-STD-002 and JESD 22-B102, rated for solder dip up to 275 °C for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction or transient clamping | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode (banded end) | Current exit point during avalanche conduction | Connected to protected line (e.g., 24 V rail); clamps transients to VC relative to anode reference |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ36A | DO-214AC (SMA) package; 36.0–40.0 V VBR; 58.1 V VC at 25.4 A; 400 W PPPM | Lower power rating and surface-mount format - suitable only for lower-energy transients or space-constrained layouts | Select when board real estate is limited and surge threat level is ≤IEC 61000-4-5 Level 2; not drop-in for 1N6284A-E3/54's 1500 W requirement |
| ON Semiconductor 1.5KE36A | Same 1.5KE package, identical VBR/VC/PPPM specs; RoHS-compliant but no AEC-Q101 qualification option | Functionally interchangeable in commercial industrial use; lacks automotive-grade variant suffix (e.g., HE3) | Choose for cost-sensitive non-automotive applications where Vishay's E3/54 tape-and-reel packaging is not required |
Compared with Littelfuse SMAJ36A and ON Semiconductor 1.5KE36A, the 1N6284A-E3/54 offers higher surge robustness in the same legacy axial package, full RoHS compliance with JESD 201 Class 1A whisker resistance, and direct support for tape-and-reel automated insertion - making it optimal for high-reliability industrial power entry designs requiring proven 1500 W handling.

FAQ
What is the breakdown voltage range of the 1N6284A-E3/54?
The 1N6284A-E3/54 has a guaranteed breakdown voltage (VBR) range of 34.2 V to 37.8 V at a test current of 1.0 mA, measured per JEDEC standard. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margining in 24–36 V systems. The value is confirmed in Vishay's official datasheet document 88301, revision 09-Aug-2022.
Is the 1N6284A-E3/54 unidirectional or bidirectional?
The 1N6284A-E3/54 is a unidirectional Transient Voltage Suppressor, as indicated by the "A" suffix and absence of "CA" in its designation. It conducts only in reverse bias during avalanche, with the banded end serving as the cathode. Bidirectional variants (e.g., 1N6284CA) are separate part numbers and not functionally interchangeable with the 1N6284A-E3/54.
What is the clamping voltage of the 1N6284A-E3/54 at its rated peak pulse current?
The 1N6284A-E3/54 clamps to a maximum of 49.9 V at its rated peak pulse current of 30.1 A, defined under the standard 10/1000 µs double-exponential waveform. This VC value directly determines the maximum voltage stress imposed on protected circuitry during surge events and is validated per JEDEC test conditions in the Vishay datasheet.
Does the 1N6284A-E3/54 meet automotive qualification standards?
The base 1N6284A-E3/54 is a commercial-grade part and is not AEC-Q101 qualified. However, Vishay offers the 1N6284AHE3_B variant (with "HE3" suffix) that is AEC-Q101 qualified for automotive applications. Engineers requiring automotive compliance must specify the HE3 version - the 1N6284A-E3/54 itself is intended for industrial and telecom use where AEC-Q101 is not mandated.
What package type does the 1N6284A-E3/54 use, and what are its key mechanical features?
The 1N6284A-E3/54 uses the DO-201AD package (Case Style 1.5KE), featuring axial leads with 0.375" (9.5 mm) length, molded UL 94 V-0 epoxy body, and matte tin-plated terminals compliant with J-STD-002. Its dimensions and lead finish support wave soldering, selective reflow, and manual assembly - all documented in Vishay's mechanical drawings within datasheet 88301.
