Product details
Overview
1.5KE100ARL4G from ON Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) diode designed for parallel clamping protection of sensitive electronics. It features a 85.5 V working peak reverse voltage (VRWM), 100 V breakdown voltage (VBR) at 1 mA test current, and clamps to ≤137 V at 11 A peak pulse current - enabling robust surge suppression in power supply input stages and industrial control interfaces.
For engineers reviewing the 1.5KE100ARL4G datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM margin over operating voltage, clamping ratio (VC/VBR), UL 497B recognition for isolated loop circuits, ESD Class 3 (>16 kV HBM) rating, and axial leaded Surmetic package compatibility with through-hole PCB assembly.
Technical Context
This device operates as a Zener-based avalanche clamp, triggered when transient voltage exceeds its specified VBR. Its low dynamic impedance (<1 Ω typical near VBR) and sub-1 ns response time ensure rapid voltage limiting during ESD or lightning-induced surges.
Designed for non-repetitive 1 ms pulses, it delivers 1500 W peak power dissipation at TL ≤ 25°C, with thermal derating to 5.0 W steady-state at TL = 75°C. The cathode-band polarity marking and axial CASE 41A package support standard through-hole mounting with 260°C soldering tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 85.5 V - maximum continuous reverse operating voltage before clamping begins; must exceed circuit's peak DC/AC voltage |
| VBR @ IT=1 mA | 100 V (min) to 105 V (max) - precise avalanche initiation threshold for predictable turn-on behavior |
| VC @ IPP=11 A | ≤137 V - maximum clamped voltage seen by protected load under 1500 W transient stress |
| IPP | 11 A - peak pulse current capability at 1 ms waveform; defines surge energy handling (≈8.25 J) |
| IR @ VRWM | ≤5 μA - negligible leakage at rated working voltage, avoiding standby power loss or signal distortion |
| Response Time | <1 ns - enables suppression of fast-rising transients before downstream ICs experience overstress |
| UL Recognition | UL 497B QVGQ2 - certified for isolated loop circuit protection, including strike voltage and endurance testing |
Pinout & Package
1.5KE100ARL4G uses an axial-leaded Surmetic plastic package (CASE 41A), with cathode identified by a colored band. Leads are tin-plated, corrosion-resistant, and rated for 260°C soldering at 1/16″ from case for 10 seconds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or common return path; completes clamping loop during transient |
| Cathode | High-side connection point | Marked with band; connected to protected line (e.g., DC input rail); conducts avalanche current to ground |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W Peak Pulse Power | Supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge immunity without external series impedance |
| ESD Rating >16 kV HBM | Meets IEC 61000-4-2 Level 4 requirements for system-level ESD protection on accessible ports |
| Pb-Free Axial Package | RoHS-compliant Surmetic CASE 41A construction with fully solderable leads and void-free molding |
| Clamping Ratio VC/VBR | 1.37 max (137 V / 100 V) - tight ratio ensures minimal overvoltage exposure to protected ICs |
| Low Zener Impedance | <1 Ω near VBR - maintains stable clamping under high di/dt conditions without voltage runaway |
Applications
| Industrial Power Supply Input Protection | Telecom Line Interface Protection |
|---|---|
Use Scenario: 48 V DC telecom power feed subjected to lightning-induced surges on outdoor cable runs. IC Role / Device Role / Timing Role: Unidirectional TVS placed across input rails to clamp transients before upstream DC/DC converter.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Surface-mount SMB package; 100 W peak power; 85.5 V VRWM; 100 V VBR; 137 V VC @ 7.3 A | Lower surge rating; suited for board-level protection where space is constrained but energy levels are moderate | Select SMBJ100A for SMT designs requiring footprint reduction and lower-cost assembly; verify layout inductance does not degrade clamping performance. |
| 1N6295AG | Same axial CASE 41A package; identical electrical specs (85.5 V VRWM, 100–105 V VBR, ≤137 V VC); Pb-free, tape-and-reel variant | No functional difference; differs only in packaging format (500-unit box vs. 1500-unit tape & reel) | Choose 1N6295AG for manual prototyping or low-volume builds; 1.5KE100ARL4G preferred for automated SMT line feeding. |
Compared with SMBJ100A, 1.5KE100ARL4G delivers 15× higher surge energy handling in a through-hole package ideal for high-reliability industrial inputs; versus 1N6295AG, it offers identical protection performance with optimized logistics for high-volume production.

FAQ
What is the working peak reverse voltage (VRWM) of the 1.5KE100ARL4G?
The 1.5KE100ARL4G has a VRWM of 85.5 V, meaning it remains non-conductive up to this DC or peak AC voltage level. This value ensures reliable blocking during normal operation while allowing sufficient margin above typical 72–80 V industrial DC bus voltages before clamping initiates.
How does the 1.5KE100ARL4G compare to bidirectional TVS diodes?
The 1.5KE100ARL4G is unidirectional and intended for DC line protection where polarity is fixed - such as positive supply rails referenced to ground. Unlike bidirectional variants, it does not conduct on negative transients, making it unsuitable for AC-coupled or floating signal lines unless paired with complementary devices.
Is the 1.5KE100ARL4G RoHS compliant and lead-free?
Yes, the "G" suffix in 1.5KE100ARL4G confirms compliance with RoHS Directive 2011/65/EU. It uses a Pb-free Surmetic axial package with tin-plated leads, validated per ON Semiconductor's Pb-Free Soldering and Mounting Techniques Reference Manual.
What is the maximum clamping voltage (VC) for the 1.5KE100ARL4G under surge conditions?
The 1.5KE100ARL4G clamps to a maximum of 137 V when subjected to its rated 11 A peak pulse current (1 ms waveform). This VC value is critical for ensuring downstream components - such as 150 V-rated electrolytic capacitors or 120 V MOSFETs - remain within safe operating limits during surge events.
Does the 1.5KE100ARL4G have UL recognition for safety-critical applications?
Yes, the 1.5KE100ARL4G carries UL 497B recognition (File #E210057, category QVGQ2) for isolated loop circuit protection. This certification covers dielectric withstand, endurance conditioning, and strike voltage breakdown - validating its use in safety-isolated telecom and medical power interfaces.
