Product details
Overview
1N6283HE3/73 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 rating (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 1N6283HE3/73 datasheet, 1N6283HE3/73 pinout, 1N6283HE3/73 application, or 1N6283HE3/73 equivalent, this part serves as a RoHS-compliant, AEC-Q101-qualified TVS for high-energy transient suppression where fast response (<1 ns), low clamping ratio (VC/VBR ≈ 1.45), and robust surge handling (200 A IFSM) are required in space-constrained through-hole designs.
Technical Context
This unidirectional TVS diode uses a glass-passivated silicon junction optimized for rapid avalanche breakdown under transient overvoltage conditions. Its 10/1000 µs waveform response delivers 1500 W peak pulse power with 45.7 V clamping at 32.8 A, while maintaining <10 µA reverse leakage at 28.2 V and 25 °C.
The device exhibits a 0.098 %/°C temperature coefficient of VBR, enabling stable breakdown behavior across its full –55 °C to +175 °C operating range. Its thermal resistance (RθJL = 15.4 °C/W) supports reliable power dissipation in leaded PCB mounting without heatsinking for short-duration transients.
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 onset |
| VWM | 28.2 V - maximum continuous DC or RMS voltage the device blocks without significant leakage |
| VC @ IPPM | 45.7 V at 32.8 A - clamped voltage seen by protected circuit during 1500 W transient event |
| PPPM | 1500 W (10/1000 µs) - peak surge energy absorption capability without failure |
| IFSM | 200 A (8.3 ms half-sine) - non-repetitive forward surge current rating for inrush or fault events |
| TJ Range | –55 °C to +175 °C - enables deployment in under-hood automotive and industrial environments |
| Leakage @ VWM | ≤1.0 µA at 25 °C - ensures minimal standby power loss in always-on systems |

Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable, low-noise avalanche performance and long-term reliability under repeated surges |
| 1500 W peak pulse power (10/1000 µs) | Protects against severe lightning-induced or inductive-switching transients per IEC 61000-4-5 Level 4 |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive powertrain and chassis applications requiring zero defect field performance |

Applications
| Automotive Power Input Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: 12 V/24 V battery-fed ECUs exposed to load dump (ISO 16750-2) and alternator ripple. IC Role / Device Role / Timing Role: Primary clamping element placed between power rail and ground to limit transient voltage to safe levels for PMICs and microcontrollers. Use Value: Withstands 1500 W pulses and maintains VC ≤ 45.7 V, preventing latch-up or gate oxide rupture in downstream 3.3 V/5 V logic. |
Use Scenario: Analog output lines (4–20 mA, 0–10 V) from pressure/temperature sensors in factory automation. IC Role / Device Role / Timing Role: Unidirectional TVS installed at connector entry point to divert induced surges from field wiring before reaching ADC front-end. Use Value: Low 1.0 µA leakage at 28.2 V avoids measurement offset; fast <1 ns response prevents transient coupling into precision amplifiers. |
| Telecom DC Power Feeds | Consumer Appliance Motor Drive Protection |
Use Scenario: -48 V DC distribution in base station power supplies subject to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Secondary overvoltage clamp after upstream MOVs, providing precise, low-clamp backup protection for DC-DC converters. Use Value: Tight VBR tolerance (±5.2%) ensures predictable coordination with upstream protectors; AEC-Q101 qualification supports extended field life. |
Use Scenario: Brushed DC motor control boards in washing machines or HVAC blowers experiencing commutation spikes. IC Role / Device Role / Timing Role: Mounted across motor terminals or H-bridge outputs to absorb inductive kickback energy. Use Value: 200 A IFSM rating handles repetitive switching surges; 175 °C TJmax accommodates enclosed thermal environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33A-E3/52 | Surface-mount SMB package (vs. axial 1.5KE); same VBR (31.4–34.7 V), slightly lower PPPM (600 W) | Requires PCB redesign for SMT placement; better suited for high-density layouts with automated assembly | Select when board space is constrained and reflow compatibility is prioritized over through-hole serviceability. |
| 1.5KE33AHE3/73 | Same die, identical electrical specs, but commercial-grade (non-AEC-Q101); identical 1.5KE package and marking | Lacks automotive qualification; suitable for industrial/commercial applications where AEC-Q101 is not mandated | Choose for cost-sensitive non-automotive designs where full AEC-Q101 validation is unnecessary. |
Compared with 1N6283HE3/73, SMBJ33A-E3/52 trades mechanical robustness and surge margin for compactness, while 1.5KE33AHE3/73 offers identical performance without automotive qualification - enabling selection based on qualification requirements and assembly method rather than electrical compromise.

FAQ
What is the clamping voltage of the 1N6283HE3/73 under maximum rated surge current?
The 1N6283HE3/73 clamps to 45.7 V at its rated peak pulse current of 32.8 A (10/1000 µs waveform). This value is measured per JEDEC standard test conditions and reflects the maximum voltage imposed on the protected circuit during a full 1500 W transient event. The clamping voltage remains stable across temperature due to the device's low 0.098 %/°C VBR coefficient.
Is the 1N6283HE3/73 suitable for automotive applications?
Yes, the 1N6283HE3/73 is AEC-Q101 qualified, making it suitable for automotive applications including engine control units, body electronics, and infotainment power supplies. Its –55 °C to +175 °C operating range, 200 A IFSM, and validated surge performance meet stringent automotive reliability requirements defined in ISO 16750-2 and ISO 7637-2.
How does the 1N6283HE3/73 differ from the standard 1N6283A?
The 1N6283HE3/73 adds two key qualifications over the base 1N6283A: RoHS compliance (E3 suffix) and AEC-Q101 qualification (HE3 suffix). It also meets JESD 201 Class 2 whisker resistance, whereas 1N6283A is commercial-grade only. Electrically, both share identical VBR, VWM, VC, and PPPM specifications.
What is the maximum reverse leakage current for the 1N6283HE3/73 at rated standoff voltage?
The 1N6283HE3/73 exhibits a maximum reverse leakage current of 1.0 µA at its maximum working voltage (VWM = 28.2 V) and ambient temperature of 25 °C. This low leakage ensures minimal impact on system power budget and signal integrity in always-on or low-power circuits such as sensor interfaces and battery-backed modules.
Can the 1N6283HE3/73 be used in bidirectional configurations?
No, the 1N6283HE3/73 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants in this family use the "CA" suffix (e.g., 1N6283CA). Using a unidirectional device in a bidirectional AC or differential line application would result in forward conduction during negative half-cycles and potential failure.
