Product details
Overview
1.5KE82ARL4G from ON Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) diode designed for parallel clamping protection of sensitive electronics against ESD, lightning surges, and inductive switching transients. It features a 70.1 V working peak reverse voltage (VRWM), 82 V breakdown voltage (VBR) at 1 mA test current, and clamps to 113 V at 13.3 A peak pulse current - used in power supply input stages, industrial I/O protection, and telecom line interfaces.
For engineers reviewing the 1.5KE82ARL4G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, UL 497B-certified surge performance, axial lead package details, and real-world protection use cases - all validated against ON Semiconductor's official 1N6267A Series documentation (Rev. 13, Oct. 2011).
Technical Context
This device operates as a silicon avalanche diode with fast <1 ns response time and low dynamic impedance, enabling effective clamping during sub-microsecond transients. Its unidirectional polarity requires cathode connection to the protected line and anode to ground, and it complies with Class 3 ESD immunity (>16 kV HBM) and UL 497B for isolated loop circuit protection.
The 1.5KE82ARL4G is rated for 1500 W nonrepetitive peak pulse power at 1 ms, with thermal resistance of 20 °C/W (junction-to-lead) and steady-state dissipation of 5.0 W at TL ≤ 75°C. Derating curves apply above ambient temperatures, and its Surmetic axial plastic case (Case 41A) supports manual or wave soldering at 260°C for 10 seconds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W @ 1 ms - sustains single high-energy surges without failure in AC/DC input protection |
| Working Peak Reverse Voltage (VRWM) | 70.1 V - maximum continuous DC or peak AC voltage the device blocks before clamping begins |
| Breakdown Voltage (VBR) | 82 V @ 1 mA - precise avalanche onset threshold ensuring predictable clamping activation |
| Clamping Voltage (VC) | 113 V @ 13.3 A IPP - limits transient voltage seen by downstream ICs to safe levels |
| Leakage Current (IR) | <5 µA @ VRWM - negligible standby power loss and no signal distortion in high-impedance circuits |
| Response Time | <1 ns - reacts faster than most system-level transients, minimizing overshoot before clamping |
| ESD Rating | Class 3 (>16 kV HBM) - meets stringent electrostatic discharge immunity requirements for end-equipment certification |
Pinout & Package
1.5KE82ARL4G uses an axial-leaded Surmetic plastic package (Case 41A), with cathode identified by a colored band. Leads are tin-plated, solderable, and rated for 260°C for 10 seconds at 1/16 inch from case. Mounting position is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground; completes clamping path during transient events |
| Cathode | Protected line terminal | Connected to the line being protected (e.g., DC input rail); polarity band marks this terminal |
Key Features
| Feature | Design Value |
|---|---|
| UL 497B Recognition | Qualified for isolated loop circuit protection - enables compliance in telecom and industrial safety-critical designs |
| Pb-Free Construction | RoHS-compliant Surmetic axial package (RL4G suffix) - supports lead-free manufacturing without derating |
| Low Clamping Ratio | VC/VBR = 113/82 ≈ 1.38 - tight voltage margin ensures robust protection without overdesigning downstream components |
| High Surge Robustness | Withstands 200 A forward surge (IFSM) - survives repetitive inrush or fault currents in power systems |
| Thermal Stability | 0.105 %/°C VBR temperature coefficient - predictable voltage shift across −65°C to +175°C operating range |
Applications
| Industrial Power Supply Input Protection | Telecom Line Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ80A | Surface-mount SMB package; lower 600 W peak power; 80 V VRWM; 125 V VC @ 4.8 A | Better suited for PCB space-constrained designs but lacks 1.5KE82ARL4G's axial lead mechanical robustness and UL 497B recognition | Select when board area is critical and surge energy remains below 600 W |
| 1.5KE82A | Same electrical specs and Case 41A package; differs only in packaging format (bulk box vs. tape & reel) | No functional difference - identical performance and mounting; RL4G denotes Pb-free tape-and-reel delivery | Choose 1.5KE82ARL4G for automated assembly; choose 1.5KE82A for manual prototyping or low-volume builds |
Compared with SMBJ80A, 1.5KE82ARL4G delivers 2.5× higher surge energy handling and certified loop protection, while 1.5KE82A offers identical protection in a different logistics format - making 1.5KE82ARL4G optimal for high-reliability industrial production requiring UL compliance and tape-and-reel feed.

FAQ
What is the clamping voltage of the 1.5KE82ARL4G under maximum surge conditions?
The 1.5KE82ARL4G clamps to 113 V at its rated peak pulse current of 13.3 A (IPP), per ON Semiconductor's 1N6267A Series datasheet (Rev. 13). This value is measured using the standardized 1 ms exponential waveform (Figure 5), and represents the maximum voltage imposed on protected circuitry during a full-power transient event. Engineers must ensure downstream components tolerate this clamping level.
Is the 1.5KE82ARL4G RoHS compliant and lead-free?
Yes, the "RL4G" suffix in 1.5KE82ARL4G explicitly denotes a Pb-free Surmetic axial package compliant with RoHS Directive 2011/65/EU. The device uses lead-free terminations and thermosetting plastic encapsulation, and ON Semiconductor confirms full compliance in its packaging documentation and material declarations.
Does the 1.5KE82ARL4G have UL recognition, and for what standard?
Yes, the 1.5KE82ARL4G carries UL Recognition under file E210057 for standard UL 497B - specifically qualifying it for use in isolated loop circuit protection. This certification covers dielectric withstand, endurance conditioning, and strike voltage breakdown testing, distinguishing it from generic TVS diodes lacking third-party safety validation.
How does the 1.5KE82ARL4G differ from the 1.5KE82A variant?
The 1.5KE82ARL4G and 1.5KE82A share identical electrical specifications, package (Case 41A), and surge ratings. The sole difference is packaging format: "RL4G" indicates 1500-piece tape-and-reel delivery optimized for SMT placement, while "A" denotes 500-unit bulk boxes for manual assembly or prototyping - both are Pb-free and functionally interchangeable.
What is the maximum operating temperature range for the 1.5KE82ARL4G?
The 1.5KE82ARL4G is rated for an operating and storage temperature range of −65°C to +175°C, as specified in the Absolute Maximum Ratings table of the ON Semiconductor 1N6267A Series datasheet. Its thermal resistance (RJL = 20 °C/W) and derating curves (Figure 4) allow reliable operation up to 175°C junction temperature when mounted with proper lead length and airflow.
