Product details
Overview
1N6283HE3/54 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 33 V breakdown voltage (VBR = 31.4–34.7 V at IT = 1.0 mA), 28.2 V maximum working peak reverse voltage (VWM), 45.7 V clamping voltage (VC) at 32.8 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - suitable for automotive ECU power input protection.
For engineers reviewing the 1N6283HE3/54 datasheet, 1N6283HE3/54 pinout, 1N6283HE3/54 application, or 1N6283HE3/54 equivalent, this part delivers verified AEC-Q101 qualification, JEDEC-standard 1.5KE package compatibility, glass-passivated junction reliability, and low incremental surge resistance for robust transient suppression in industrial and automotive environments.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR, it avalanches rapidly (<1 ns response) to divert surge current away from downstream ICs. Its 1.5KE case style supports high thermal dissipation (RθJL = 15.4 °C/W) and handles 200 A non-repetitive forward surge (IFSM) per 8.3 ms half-sine wave.
The device is rated for -55 °C to +175 °C operating junction temperature, complies with JESD 201 Class 2 whisker resistance (HE3 suffix), and meets UL 94 V-0 flammability requirements. Its 3.5 V forward voltage (VF) at 100 A confirms low conduction loss during clamping events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 31.4 V / 34.7 V at 1.0 mA - defines precise avalanche initiation threshold for repeatable clamping behavior |
| VWM | 28.2 V - maximum continuous reverse voltage before leakage exceeds 1.0 µA, ensuring no false triggering |
| VC @ IPPM | 45.7 V at 32.8 A - clamping voltage under full 1500 W surge, limiting stress on protected 3.3 V/5 V logic |
| PPPM | 1500 W - peak pulse power handling with 10/1000 µs waveform, sufficient for ISO 7637-2 Pulse 1/2b/5a |
| IFSM | 200 A - non-repetitive forward surge rating, enabling survival of high-energy load dump transients |
| TJ max | +175 °C - extended junction temperature range supports under-hood automotive placement |
| Package | 1.5KE (DO-201AD) - industry-standard axial leaded package with 0.375" lead length, compatible with automated through-hole assembly |
Pinout & Package
1N6283HE3/54 uses the standard DO-201AD (1.5KE) axial package: cathode indicated by color band; leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, with JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction or clamping | Connected to system ground or low-side return path; enables shunt diversion of positive transients |
| Cathode | Current exit point during reverse-biased clamping | Connected to protected line (e.g., 24 V rail); avalanche occurs here when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure |
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS power domains |
| 1500 W peak pulse power | Handles ISO 16750-2 load dump surges up to 35 V × 43 A without degradation |
| Ultra-fast response time | <1 ns clamping activation prevents nanosecond-scale transients from reaching sensitive IC inputs |
| Low incremental surge resistance | Minimizes VC overshoot during high di/dt events, improving protection margin for 3.3 V microcontrollers |
Applications
| Automotive Power Input Protection | Industrial PLC Digital I/O Protection |
|---|---|
Use Scenario: 24 V battery-fed ECU power rail exposed to ISO 7637-2 Pulse 5a (load dump). IC Role / Device Role / Timing Role: Shunt clamping device placed between VIN and GND, activated within 1 ns to clamp transients above 33 V. Use Value: Limits rail voltage to ≤45.7 V during 1500 W surges, preventing damage to 36 V-rated DC-DC controllers and CAN transceivers. |
Use Scenario: 24 V digital input channel in programmable logic controller subject to inductive switching noise. IC Role / Device Role / Timing Role: Primary-level transient suppressor on field-side signal line, absorbing energy before optocoupler input stage. Use Value: Clamps 1 kV/1 µs fast transients to safe levels while maintaining <1 µA leakage at 24 V nominal, preserving input logic thresholds. |
| Telecom Line Interface Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: RS-485 data line in outdoor base station equipment subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS on VCC-to-GND path of isolated RS-485 transceiver power supply. Use Value: Absorbs 1500 W coupling energy from secondary-side surges, protecting isolated DC-DC converter and transceiver ICs. |
Use Scenario: 12 V control rail in smart washing machine motor driver board exposed to relay coil flyback. IC Role / Device Role / Timing Role: Clamp diode across relay coil or MOSFET drain-source, suppressing 100 V+ inductive spikes. Use Value: Limits spike amplitude to 45.7 V with sub-ns response, eliminating need for snubber RC networks and reducing BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33A-E3/52 | Smaller SMB (DO-214AA) package; 33 V VBR, 53.3 V VC at 23.3 A; 600 W PPPM | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a due to lower power rating | Select when board space is constrained and surge energy is ≤600 W (e.g., USB VBUS, sensor interfaces) |
| 1.5KE33AHE3_A | Same 1.5KE package and electrical specs, but HE3_A suffix indicates earlier revision code and JESD 201 Class 1A whisker test | Identical clamping performance and thermal profile; differs only in whisker resistance class and traceability | Choose for legacy design continuity or where Class 1A whisker compliance suffices; HE3/54 offers enhanced mechanical robustness |
Compared with SMBJ33A-E3/52, 1N6283HE3/54 provides 2.5× higher pulse power and superior thermal dissipation for harsh automotive environments; versus 1.5KE33AHE3_A, it delivers upgraded JESD 201 Class 2 whisker resistance for extended reliability in high-vibration applications.

FAQ
What is the exact breakdown voltage range for 1N6283HE3/54?
The 1N6283HE3/54 has a guaranteed breakdown voltage (VBR) range of 31.4 V to 34.7 V at a test current of 1.0 mA, measured per JEDEC standard. This tight 10.5% tolerance ensures predictable clamping onset across production lots and temperature extremes from -55 °C to +175 °C, critical for consistent protection in automotive power systems.
Is 1N6283HE3/54 AEC-Q101 qualified?
Yes, 1N6283HE3/54 is explicitly AEC-Q101 qualified per Vishay documentation (Document Number 88301, Revision 09-Aug-2022). The HE3 suffix denotes RoHS compliance and AEC-Q101 qualification, validated for automotive applications including engine control modules, body control units, and ADAS subsystems requiring zero-failure reliability.
What does the "/54" in 1N6283HE3/54 indicate?
The "/54" suffix in 1N6283HE3/54 specifies the packaging configuration: 1400 pieces per 13-inch diameter paper tape and reel, with preferred package code "54". This format enables automated SMT-compatible through-hole insertion using standard pick-and-place feeders, supporting high-volume manufacturing of automotive and industrial PCBs.
How does 1N6283HE3/54 compare to bidirectional TVS diodes like 1N6283HE3/54C?
The 1N6283HE3/54 is unidirectional and intended for DC rail protection where polarity is fixed; its counterpart 1N6283HE3/54C is bidirectional (denoted by "CA" or "C" suffix) and used in AC-coupled or differential signal lines. They share identical VBR and PPPM, but the unidirectional version offers lower leakage and tighter VF spec (3.5 V at 100 A), making it optimal for 24 V power rails.
What is the thermal resistance and maximum power dissipation of 1N6283HE3/54?
The 1N6283HE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 15.4 °C/W and a steady-state power dissipation (PD) of 6.5 W at TL = 75 °C. This allows effective heat transfer to PCB copper or heatsinks, sustaining repeated transient events without thermal runaway - essential for automotive under-hood operation where ambient temperatures exceed 105 °C.
