Product details
Overview
1N6283AHE3_B/C from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 31.4 V to 34.7 V breakdown voltage (VBR) at 1.0 mA test current, 28.2 V maximum stand-off 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 - used to safeguard MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive control modules.
For engineers reviewing the 1N6283AHE3_B/C datasheet, 1N6283AHE3_B/C pinout, 1N6283AHE3_B/C application, or 1N6283AHE3_B/C equivalent, this part delivers verified AEC-Q101 qualification (HE3 suffix), RoHS-compliant matte tin-plated leads, 175 °C max junction temperature, and glass passivated junction for stable clamping under repetitive surge conditions.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging silicon avalanche breakdown to divert transient energy away from downstream circuitry. Its 1500 W peak pulse power handling and low incremental clamping resistance ensure effective suppression of inductive switching spikes and lightning-induced surges on DC rails and low-speed signal paths.
The device exhibits a temperature coefficient of VBR of +0.098 %/°C and is rated for -55 °C to +175 °C operating junction temperature. With 75 °C/W junction-to-ambient thermal resistance and 15.4 °C/W junction-to-lead resistance, it supports reliable operation under sustained surge duty cycles when mounted on PCBs with adequate copper pour or lead heatsinking.
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 reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 45.7 V at 32.8 A - clamped voltage during 10/1000 µs surge, limiting stress on protected ICs |
| PPPM | 1500 W - peak transient power dissipation capability without degradation under standardized surge waveform |
| IFSM | 200 A - non-repetitive forward surge current rating (8.3 ms half-sine), critical for input rectifier stage protection |
| TJ max | +175 °C - enables use in under-hood automotive and high-temperature industrial environments |
| RθJA | 75 °C/W - thermal resistance indicating need for PCB copper area or heatsink for sustained power dissipation |

The 1N6283AHE3_B/C has a guaranteed breakdown voltage (VBR) range of 31.4 V to 34.7 V at 1.0 mA test current, measured per JEDEC standard. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable design margining in 24 V system protection schemes.
Is the 1N6283AHE3_B/C suitable for automotive applications?
Yes, the 1N6283AHE3_B/C carries the HE3 suffix, confirming AEC-Q101 qualification per Vishay documentation. It is rated for -55 °C to +175 °C operation and validated for automotive powertrain and body electronics, including protection against ISO 7637-2 load dump and jump-start transients.
How does the 1N6283AHE3_B/C differ from the 1.5KE33AHE3_B/C?
The 1N6283AHE3_B/C and 1.5KE33AHE3_B/C are identical devices - same electrical characteristics, package, thermal performance, and qualification status. The difference lies only in JEDEC (1N6283A) versus manufacturer (1.5KE33A) part numbering conventions; both share the HE3_B/C suffix and are fully interchangeable.
What is the clamping voltage of the 1N6283AHE3_B/C at its rated peak pulse current?
The 1N6283AHE3_B/C clamps to a maximum of 45.7 V at its rated peak pulse current (IPPM) of 32.8 A under the standard 10/1000 µs waveform. This value is specified in the Vishay datasheet (Document Number: 88301) and reflects worst-case clamping performance at TA = 25 °C.
Does the 1N6283AHE3_B/C have bidirectional capability?
No, the 1N6283AHE3_B/C 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), which are distinct parts with symmetrical clamping in both polarities.
