Product details
Overview
1N6283-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 33 V breakdown voltage (VBR = 31.4–34.7 V at 1.0 mA), 28.2 V maximum working voltage (VWM), 45.7 V clamping voltage (VC) at 32.8 A peak pulse current, 1500 W peak pulse power (10/1000 µs), and operates across –55 °C to +175 °C junction temperature range - deployed in automotive power supply inputs and industrial sensor interface protection.
For engineers reviewing the 1N6283-E3/54 datasheet, 1N6283-E3/54 pinout, 1N6283-E3/54 application, or 1N6283-E3/54 equivalent, this page delivers verified electrical parameters, JEDEC 1.5KE package details, clamping performance under transient stress, thermal resistance (RθJA = 75 °C/W), and direct alternatives with documented VBR, VC, and IPPM differences.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction to achieve sub-nanosecond response time (<1 ns) and low incremental surge resistance. Its 1500 W peak pulse rating is defined per 10/1000 µs waveform with 0.01 % duty cycle, and it maintains stable clamping up to TJ = 175 °C.
It complies with JEDEC standard test conditions for transient suppression, including 8.3 ms half-sine surge current rating (IFSM = 200 A) and forward voltage limit of 3.5 V at 100 A - critical for minimizing conduction loss during fault events in high-current power circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 31.4 V / 34.7 V at 1.0 mA - defines precise voltage threshold where clamping initiates; ensures reliable turn-on before downstream IC damage. |
| VWM | 28.2 V - maximum continuous reverse operating voltage; must exceed normal circuit operating voltage to prevent leakage or false triggering. |
| VC @ IPPM | 45.7 V at 32.8 A - clamped voltage seen by protected circuit during 10/1000 µs transient; determines safe margin for 33 V-rated components. |
| PPPM | 1500 W - peak transient energy absorption capacity; enables robust protection against lightning-induced surges and inductive switching spikes. |
| IFSM | 200 A (8.3 ms half-sine) - surge current handling without failure; supports protection in high-energy automotive load-dump scenarios. |
| TJ max. | +175 °C - extended junction temperature rating allows use in under-hood automotive and high-ambient industrial environments. |
| RθJA | 75 °C/W - thermal resistance from junction to ambient; informs heatsinking requirements when operating near power dissipation limits. |
Pinout & Package
Package: JEDEC DO-201AD (Case Style 1.5KE), axial-leaded, molded epoxy body with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to lower-potential side of protected line | Enables unidirectional clamping - conducts only when cathode is > anode by ≥ VF (~3.5 V), blocking reverse leakage below VWM. |
| Cathode | Current exit point in forward bias; marked with color band; connected to higher-potential side (e.g., VIN) | Serves as reference node for clamping action - shunts transient current to ground or return path when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| 1500 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-ground) without derating in compact PCB layouts. |
| Sub-nanosecond response time | Clamps transients before sensitive logic or analog circuitry experiences overvoltage stress - critical for protecting CAN, LIN, and RS-485 interfaces. |
| AEC-Q101 qualified option available | HE3 suffix variants meet automotive qualification; 1N6283-E3/54 is commercial grade but shares identical die and package construction. |
| UL 94 V-0 rated epoxy molding | Provides flame-retardant mechanical encapsulation essential for industrial control panels and transportation electronics. |

FAQ
What is the breakdown voltage tolerance of the 1N6283-E3/54?
The 1N6283-E3/54 has a specified breakdown voltage range of 31.4 V to 34.7 V at 1.0 mA test current, representing ±5.2 % tolerance about the nominal 33 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes from –55 °C to +175 °C, critical for maintaining safety margins in regulated power systems.
Does the 1N6283-E3/54 have AEC-Q101 qualification?
The 1N6283-E3/54 is a commercial-grade part and does not carry AEC-Q101 qualification. However, its identical die and package are used in the AEC-Q101-qualified variant 1N6283AHE3_B (with HE3 suffix). Engineers requiring automotive qualification should specify the HE3 version; the 1N6283-E3/54 remains suitable for industrial and telecom applications where AEC-Q101 is not mandated.
What is the maximum clamping voltage of the 1N6283-E3/54 under surge conditions?
The 1N6283-E3/54 exhibits a maximum clamping voltage (VC) of 45.7 V when subjected to its rated peak pulse current of 32.8 A using the standardized 10/1000 µs waveform. This value is guaranteed per datasheet testing and defines the upper voltage limit imposed on protected circuitry during worst-case transient events - essential for verifying compatibility with downstream 33 V or 40 V tolerant ICs.
Can the 1N6283-E3/54 be used in bidirectional configurations?
No, the 1N6283-E3/54 is strictly a unidirectional TVS diode, as indicated by the "A" suffix and absence of "CA" in its designation. Bidirectional operation requires a part like 1N6283CA (or 1.5KE33CA), which has symmetrical clamping in both polarities. Using 1N6283-E3/54 in AC or floating applications risks catastrophic failure due to reverse conduction beyond VWM.
What is the thermal resistance of the 1N6283-E3/54, and how does it affect layout?
The 1N6283-E3/54 has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W under standard JEDEC test conditions. This value assumes minimal copper area; designers must allocate ≥1 cm² of 2-oz copper pour connected to both leads to maintain safe junction temperatures during repetitive surge events or elevated ambient conditions - especially critical in enclosed automotive junction boxes.
