Product details
Overview
1N6280AHE3_B/C 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 24 V breakdown voltage (VBR = 22.8–25.2 V at 1.0 mA), 20.5 V stand-off voltage (VWM), 33.2 V clamping voltage (VC) at 45.2 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 and automotive electronics.
For engineers reviewing the 1N6280AHE3_B/C datasheet, 1N6280AHE3_B/C pinout, 1N6280AHE3_B/C application, or 1N6280AHE3_B/C equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), junction temperature range (–55 to +175 °C), and RoHS-compliant HE3 packaging with JESD 201 Class 2 whisker resistance.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: it remains high-impedance below VWM (20.5 V), breaks down sharply at VBR (min 22.8 V), and clamps transients to ≤33.2 V at 45.2 A. Its glass-passivated junction enables sub-nanosecond response time and low incremental surge resistance.
Rated for 1500 W peak pulse power (10/1000 µs), it supports repetitive surges at 0.01 % duty cycle and handles 200 A non-repetitive forward surge (8.3 ms half-sine). Thermal design is guided by RθJL = 15.4 °C/W (junction-to-lead) and derating curves valid up to TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V at 1.0 mA - defines precise voltage threshold for avalanche conduction onset |
| VWM | 20.5 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 33.2 V at 45.2 A - clamping voltage limiting transient energy delivered to protected circuit |
| PPPM | 1500 W - peak pulse power handling for 10/1000 µs waveform, critical for lightning/inductive spike immunity |
| TJ Range | –55 °C to +175 °C - enables operation in under-hood automotive and industrial environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, informs heatsinking requirements on PCB |
| AEC-Q101 | Qualified - validated for automotive-grade reliability per stress test standard |
Pinout & Package
1N6280AHE3_B/C uses the industry-standard Case Style 1.5KE axial-leaded package (DO-201AD), with cathode indicated by a color band. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and rated for solder dip at 275 °C max for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to ground or low-impedance return when protecting positive rail; conducts during reverse transient |
| Cathode | Protected line connection / clamping node | Connected to line being protected (e.g., 24 V supply); avalanche conduction initiates here during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |
| 1500 W peak pulse power (10/1000 µs) | Provides robust protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 24 V systems |
| AEC-Q101 qualified (HE3_B variant) | Validated for automotive applications including engine control units and body electronics |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), preserving downstream IC integrity |
| JESD 201 Class 2 whisker resistance | Ensures lead finish stability in high-humidity or high-temperature storage and assembly environments |
Applications
| Industrial PLC I/O Protection | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A-E3/52 | Lower PPPM (600 W), SMC package (surface-mount), VC = 38.9 V @ 15.4 A | Better suited for space-constrained PCBs; lower surge capacity limits use to Level 3 IEC 61000-4-5 | Select when board area is constrained and peak surge energy is ≤600 W; verify layout thermal relief for SMB footprint. |
| 1.5KE24A-E3/54 | Same electrical specs and DO-201AD package, but commercial-grade (non-AEC-Q101), E3 suffix only (no HE3_B/C) | Lacks automotive qualification and JESD 201 Class 2 whisker resistance; suitable for industrial/commercial use only | Choose for cost-sensitive non-automotive designs where AEC-Q101 and enhanced lead finish are not required. |
Compared with 1N6280AHE3_B/C, SMBJ24A-E3/52 trades surge capacity and through-hole robustness for compactness, while 1.5KE24A-E3/54 matches performance but omits automotive qualification and whisker-resistant plating - making 1N6280AHE3_B/C the sole option when both AEC-Q101 compliance and axial-leaded mechanical reliability are mandatory.

FAQ
What is the breakdown voltage tolerance of the 1N6280AHE3_B/C?
The 1N6280AHE3_B/C has a specified breakdown voltage range of 22.8 V to 25.2 V at 1.0 mA test current, representing ±5 % tolerance around the nominal 24 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports reliable coordination with downstream overvoltage protection circuits. The 1N6280AHE3_B/C datasheet confirms this range under "ELECTRICAL CHARACTERISTICS" Table on page 2.
Is the 1N6280AHE3_B/C suitable for automotive applications?
Yes - the 1N6280AHE3_B/C is AEC-Q101 qualified (as indicated by the HE3_B/C suffix), tested for temperature cycling, humidity bias, and mechanical shock per automotive reliability standards. Its –55 °C to +175 °C operating range and JESD 201 Class 2 whisker-resistant leads make it appropriate for under-hood and body electronics. The 1N6280AHE3_B/C meets requirements for ECUs, lighting modules, and infotainment power rails.
How does the clamping voltage of the 1N6280AHE3_B/C compare to its breakdown voltage?
The 1N6280AHE3_B/C clamps at 33.2 V when subjected to its rated 45.2 A peak pulse current (10/1000 µs), which is approximately 38 % above its minimum breakdown voltage of 22.8 V. This VC–VBR margin reflects low dynamic impedance and ensures protected circuits see minimal overvoltage during surge events. The 1N6280AHE3_B/C datasheet lists VC = 33.2 V explicitly in the "ELECTRICAL CHARACTERISTICS" table.
What is the meaning of the 'HE3_B/C' suffix in 1N6280AHE3_B/C?
The 'HE3' denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance; 'B' indicates revision level; 'C' specifies packaging in 13" paper tape and reel (1400 pcs/reel). This full suffix distinguishes the automotive-grade, high-reliability variant from commercial versions like 1.5KE24A-E3/54. The 1N6280AHE3_B/C ordering information is detailed in the "ORDERING INFORMATION" section of the Vishay document 88301.
Can the 1N6280AHE3_B/C be used in bidirectional configurations?
No - the 1N6280AHE3_B/C is a unidirectional TVS diode, identified by the 'A' suffix (vs. 'CA' for bidirectional). It protects only against reverse-polarity transients on positively referenced lines. For bidirectional protection (e.g., AC lines or data buses), Vishay offers variants such as 1N6280CAHE3_B/C. The 1N6280AHE3_B/C datasheet explicitly states polarity as unidirectional and shows cathode band marking, confirming its single-direction functionality.
