Product details
Overview
1N6280AG from ON Semiconductor is a unidirectional 1500 W Mosorb transient voltage suppressor (TVS) diode in axial lead Surmetic plastic package, designed for parallel clamping protection of sensitive electronics. It features a 24 V breakdown voltage (VBR = 22.8–25.2 V @ IT = 1 A), 33.2 V maximum clamping voltage (VC) at 45 A peak pulse current (IPP), and <1 ns response time - ideal for safeguarding power supply rails and interface lines in industrial control systems.
For engineers reviewing the 1N6280AG datasheet, pinout, applications, or equivalent options, key selection criteria include working peak reverse voltage (20.5 V), clamping performance under 1 ms transients, UL 497B recognition for isolated loop circuits, low zener impedance, and Pb-free axial package compatibility with through-hole reflow or hand-soldering.
Technical Context
The 1N6280AG operates as a silicon avalanche diode optimized for transient suppression in unidirectional configurations. Its breakdown voltage is tightly specified (22.8–25.2 V) with ±5% tolerance at 1 A test current, and exhibits a temperature coefficient of 0.094 %/°C - enabling predictable voltage drift across −65°C to +175°C operating range.
It delivers 1500 W peak pulse power (1 ms, 10/1000 µs waveform), supports 200 A non-repetitive forward surge current (8.3 ms half-sine), and maintains <5 µA leakage above 10 V - ensuring minimal standby power loss while providing robust ESD immunity (>16 kV HBM) and fast turn-on during fast-rising transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage (VRWM) | 20.5 V - sets maximum continuous DC or peak AC operating voltage before clamping initiates |
| Breakdown Voltage (VBR) | 22.8–25.2 V @ 1 A - defines precise avalanche onset threshold for reliable overvoltage triggering |
| Clamping Voltage (VC) | 33.2 V @ 45 A - limits protected circuit voltage during worst-case 1 ms surge, preserving downstream ICs |
| Peak Pulse Power (PPK) | 1500 W @ TL ≤ 25°C - enables handling of high-energy lightning-induced or inductive-switching transients |
| Response Time | <1 ns - ensures suppression activation before most semiconductor damage thresholds are exceeded |
| ESD Rating (HBM) | >16 kV - meets Class 3 ESD immunity for robust handling in manufacturing and field environments |
| UL Recognition | UL 497B certified - validated for use in isolated loop circuit protection per safety standard QVGQ2 |
Pinout & Package
1N6280AG uses an axial-lead Surmetic plastic package (Case 41A), with cathode indicated by a polarity band. Leads are corrosion-resistant, readily solderable, and rated for 260°C for 10 seconds at 1/16 inch from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction or transient clamp mode | Connected to lower-potential side (e.g., ground or return path) in unidirectional protection configuration |
| Cathode | Current exit terminal; marked with polarity band | Connected to protected line (e.g., 24 V rail); conducts avalanche current when line voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse rating | Supports high-energy surges without degradation - suitable for industrial power input stages and motor drive interfaces |
| Low clamping ratio (VC/VBR ≈ 1.38) | Minimizes overvoltage stress on protected ICs compared to higher-ratio TVS devices |
| Pb-free Surmetic axial package | Enables RoHS-compliant through-hole assembly with proven thermal and mechanical reliability |
| UL 497B certification | Validates suitability for safety-critical isolated loop applications such as analog sensor inputs and telecom line interfaces |
| Sub-1 ns response time | Ensures suppression activates before fast transients (e.g., EFT bursts) propagate into sensitive logic or ADC front-ends |
Applications
| Industrial Power Supply Input Protection | PLC Analog Input Channel Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1.5KE24AG | Same electrical specs and package; identical JEDEC marking (1N6280AG = 1.5KE24AG per ON Semi documentation) | No functional difference - dual-marked variant with tape-and-reel packaging option | Select 1.5KE24AG for automated assembly; 1N6280AG preferred for box-packaged manual or low-volume production |
| SMBJ24A | Surface-mount SMB package (3.5 × 4.6 mm), 600 W PPK, same VRWM/VC ratings but lower surge capacity | Used where board space is constrained and 600 W surge margin suffices; lacks UL 497B certification | Choose SMBJ24A only when layout prohibits axial components and full 1500 W rating is not required |
Compared with 1.5KE24AG, the 1N6280AG offers identical protection performance in a 500-unit box format optimized for prototyping and repair; versus SMBJ24A, it provides 2.5× higher surge rating and safety certification critical for industrial power entry designs.

FAQ
What is the breakdown voltage tolerance of the 1N6280AG?
The 1N6280AG has a breakdown voltage (VBR) specified from 22.8 V to 25.2 V at 1 A test current, representing a ±5% tolerance around the nominal 24 V rating. This tight distribution ensures consistent clamping behavior across production lots and supports reliable system-level overvoltage margining in 24 V industrial designs.
Is the 1N6280AG RoHS compliant and lead-free?
Yes, the 1N6280AG is a Pb-free device in ON Semiconductor's Surmetic axial package, as confirmed by the "G" suffix in its part number and compliance with JEDEC standards. It meets RoHS Directive 2011/65/EU and supports lead-free soldering processes up to 260°C for 10 seconds at 1/16 inch from the case body.
Does the 1N6280AG have UL recognition, and for what standard?
Yes, the 1N6280AG carries UL 497B recognition under file #E210057 for protector classification (QVGQ2). This certification validates its suitability in isolated loop circuits - including analog sensor inputs and telecom interfaces - having passed strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge testing.
How does the 1N6280AG compare to SMD TVS diodes like SMAJ24A in surge capability?
The 1N6280AG delivers 1500 W peak pulse power (1 ms), more than double the 600 W rating of SMAJ24A. Its axial package also provides superior thermal mass and lower junction-to-lead resistance (RJL = 20 °C/W), enabling higher single-pulse survivability in high-energy industrial transients where SMD variants may fail catastrophically.
Can the 1N6280AG be used in bidirectional protection circuits?
No - the 1N6280AG is strictly unidirectional and must be installed with cathode toward the protected line. For bidirectional protection, ON Semiconductor recommends pairing two 1N6280AG devices in series opposition or selecting a dedicated bidirectional part such as 1N6280A (not AG) or P6SMB24CA, which are explicitly characterized for symmetrical clamping.
