Product details
Overview
1.5KE82AG from ON Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) diode designed for parallel clamping protection of sensitive electronics. It features a working peak reverse voltage of 70.1 V, clamps at 113 V under 13.3 A peak pulse current, and delivers sub-1 ns response time with <5 µA leakage above 10 V. It is used in industrial power supplies to safeguard MOS/CMOS ICs against ESD and lightning-induced surges.
For engineers reviewing the 1.5KE82AG datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM ≥70.1 V, VC ≤113 V at IPP=13.3 A, UL 497B recognition for isolated loop circuits, ESD Class 3 (>16 kV HBM), and axial lead (Case 41A) mechanical compatibility with through-hole PCB layouts.
Technical Context
The 1.5KE82AG operates as a Zener-based avalanche clamp, triggered when transient voltage exceeds its 77.9–86.1 V breakdown range (measured at 1 mA). Its low dynamic impedance and fast turn-on enable effective suppression of 8.3 ms half-sine surges up to 1500 W without thermal runaway.
It is rated for −65 °C to +175 °C operating temperature, exhibits 0.105 %/°C VBR temperature coefficient, and maintains stable clamping performance across ambient temperatures via derated pulse handling per Figure 2 and steady-state power dissipation of 5.0 W at TL ≤75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 70.1 V - Maximum continuous reverse operating voltage before clamping begins; must exceed circuit's DC/peak operating voltage. |
| VBR (min/typ/max) | 77.9 / 82 / 86.1 V @ 1 mA - Confirmed avalanche onset range; ensures predictable triggering margin above VRWM. |
| VC @ IPP | 113 V @ 13.3 A - Clamped voltage during 1 ms surge; defines maximum stress imposed on protected downstream components. |
| PPK | 1500 W @ 1 ms - Peak single-pulse energy handling capability; validates suitability for IEC 61000-4-5 Level 4 surge events. |
| IR @ VRWM | <5 µA - Negligible leakage current at rated working voltage; prevents power loss or signal distortion in high-impedance nodes. |
| Response Time | <1 ns - Enables suppression before transient energy couples into sensitive circuitry; critical for protecting high-speed interfaces. |
| ESD Rating | Class 3 (>16 kV HBM) - Meets stringent electrostatic discharge immunity requirements for industrial and medical equipment. |
Pinout & Package
1.5KE82AG uses an axial-leaded Surmetic plastic package (Case 41A), with cathode identified by a polarity band. Leads are tin-plated, solderable at 260 °C for 10 seconds at 1/16 inch from case body. Mounting position is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current return path | Connected to ground or low-impedance reference; completes clamping loop during overvoltage event. |
| Cathode | Clamping voltage reference node | Connected to protected line (e.g., DC input rail); voltage at this terminal is clamped to ≤113 V during surge. |
Key Features
| Feature | Design Value |
|---|---|
| UL 497B Recognition | Validated for isolated loop circuit protection-enables use in telecom and process control systems requiring safety-certified surge devices. |
| Low Zener Impedance | Minimizes voltage overshoot during fast transients, ensuring clamping stays within safe margins for 3.3 V/5 V logic rails. |
| Pb-Free Axial Package | Complies with RoHS Directive 2011/65/EU; eliminates lead contamination risk in automated soldering and end-of-life recycling. |
| High Surge Capability | Withstands 1500 W non-repetitive pulses-supports robust front-end protection in AC/DC adapters and motor drive power stages. |

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; 80 V VRWM; 100 W peak power; lower IPP (12.3 A); same 113 V VC. | Requires PCB rework for SMT layout; unsuitable for high-energy surges exceeding 100 W. | Select when board space is constrained and surge threat level is moderate (e.g., consumer-grade interfaces). |
| 1.5KE82A | Same axial package and electrical specs; lacks Pb-free designation (SnPb leads); obsolete per ON Semi lifecycle policy. | No UL 497B recognition; not compliant with modern RoHS or environmental procurement mandates. | Retain only for legacy repair; 1.5KE82AG is direct replacement with enhanced compliance and traceability. |
Compared with SMBJ80A and 1.5KE82A, the 1.5KE82AG provides higher surge robustness (1500 W vs. 100 W), guaranteed Pb-free construction, and UL 497B certification-making it the preferred choice for industrial, medical, and telecom infrastructure where reliability and regulatory compliance are mandatory.

FAQ
What is the working peak reverse voltage (VRWM) of the 1.5KE82AG?
The 1.5KE82AG has a VRWM of 70.1 V, meaning it remains non-conductive up to this DC or continuous peak voltage. This value ensures reliable operation in 48 V and 60 V nominal systems while maintaining sufficient margin above normal operating voltage to avoid false triggering. The 1.5KE82AG is selected for applications where sustained reverse voltage does not exceed this threshold.
How does the 1.5KE82AG compare to the 1.5KE82A variant?
The 1.5KE82AG is the Pb-free version of the 1.5KE82A, sharing identical electrical specifications including VRWM (70.1 V), VBR (77.9–86.1 V), and VC (113 V @ 13.3 A). Unlike the 1.5KE82A, the 1.5KE82AG carries UL 497B recognition and complies with RoHS Directive 2011/65/EU. The 1.5KE82AG is the recommended active part for new designs.
What is the clamping voltage and peak pulse current rating for the 1.5KE82AG?
The 1.5KE82AG clamps to a maximum of 113 V when subjected to a 13.3 A peak pulse current (IPP), measured using the standard 1 ms exponential waveform per Figure 5. This VC/IPP pair defines the upper voltage limit imposed on protected circuitry during surge events and confirms the 1.5KE82AG's ability to handle IEC 61000-4-5-compliant transients.
Is the 1.5KE82AG certified for safety-critical applications?
Yes, the 1.5KE82AG is UL Recognized under UL 497B (File #E210057) for protector applications in isolated loop circuits. This certification covers dielectric withstand, endurance conditioning, and strike voltage breakdown testing-validating its use in medical, telecom, and industrial systems where safety agency approval is required. The 1.5KE82AG meets these requirements out-of-the-box.
What package type and mounting method does the 1.5KE82AG use?
The 1.5KE82AG uses an axial-leaded plastic package (Case 41A), with cathode indicated by a colored band. It is designed for through-hole mounting with unrestricted orientation and can be soldered at 260 °C for 10 seconds at 1/16 inch from the case body. Lead finish is Pb-free, supporting RoHS-compliant assembly processes.
