Product details
Overview
1.5KE130ARL4 from ON Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) diode designed for parallel clamping protection of sensitive electronics against ESD, lightning-induced surges, and inductive switching transients. It features a 130 V breakdown voltage (VBR = 124–137 V), 179 V maximum clamping voltage at 8.4 A peak pulse current (IPP), and <1 ns response time - deployed in power supplies, industrial controls, and communication interfaces to safeguard CMOS/MOS/Bipolar ICs.
For engineers reviewing the 1.5KE130ARL4 datasheet, pinout, applications, or equivalent options, key selection criteria include working peak reverse voltage (VRWM = 111 V), low zener impedance, UL 497B recognition for isolated loop circuits, and Pb-free axial leaded Surmetic package compatibility with automated tape-and-reel assembly.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt device: when transient voltage exceeds its VRWM (111 V), it avalanches into low-impedance conduction, limiting downstream voltage to ≤179 V at IPP = 8.4 A (1 ms, 8.3 ms half-sine). Its thermal resistance (RJL = 20 °C/W) and steady-state power rating (5.0 W @ TL ≤ 75 °C) support reliable operation under repetitive surge conditions when properly heatsinked via leads.
The device exhibits a temperature coefficient of VBR = 0.107 %/°C and maintains <5 µA leakage at VRWM, ensuring minimal standby loading on protected circuits. Its fast turn-on (<1 ns) and low dynamic impedance minimize overshoot, while UL 497B certification validates suitability for telecom and process control isolation barrier protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 111 V - Maximum continuous reverse operating voltage before clamping begins; must exceed circuit's DC/peak operating voltage. |
| VBR @ IT = 1 mA | 124–137 V - Breakdown voltage range defining avalanche onset; ensures predictable clamping threshold across production lot. |
| VC @ IPP = 8.4 A | 179 V - Maximum clamped voltage during 1500 W transient; determines worst-case stress on downstream components. |
| PPK | 1500 W - Peak pulse power handling (1 ms pulse); defines single-event surge energy absorption capability. |
| IR @ VRWM | <5 µA - Reverse leakage current at rated working voltage; negligible loading on high-impedance signal/power rails. |
| Response Time | <1 ns - Time from transient onset to clamping initiation; critical for protecting fast-edge digital interfaces. |
| UL Recognition | UL 497B (QVGV2) - Certified for isolated loop circuit protection; meets safety requirements for telecom and industrial systems. |
Pinout & Package
1.5KE130ARL4 uses an axial-leaded Surmetic plastic package (Case 41A), with cathode indicated by a polarity band. Leads are corrosion-resistant, solderable, and rated for 230 °C (10 s, 1/16″ from case).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink during clamping | Connected to ground or low-impedance return path; carries full surge current during transient events. |
| Cathode | Protected line connection | Connected to the line being protected (e.g., +12 V rail, RS-485 bus); voltage referenced to anode during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) without derating or parallel devices. |
| ESD rating >16 kV (HBM) | Meets or exceeds IEC 61000-4-2 Level 4 (15 kV contact) for board-level ESD immunity without additional staging. |
| Low clamping ratio (VC/VBR ≈ 1.42) | Minimizes overvoltage margin between clamp level and IC absolute maximum ratings - critical for 3.3 V/5 V logic protection. |
| Pb-free Surmetic axial package | RoHS-compliant, tape-and-reel compatible (1500/reel), supports automated SMT placement with axial lead form factor. |
| UL 497B certified | Validates use in safety-critical isolated interfaces (e.g., PoE, analog sensor inputs) without requiring additional system-level certification. |
Applications
| Industrial Power Supply Input Protection | RS-485/422 Communication Line Clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Surface-mount SMB package (3.5 × 3.5 mm), lower PPK = 600 W, same VRWM = 111 V, VC = 179 V @ IPP = 3.4 A | Designed for space-constrained PCBs; unsuitable for high-energy surges exceeding 600 W | Select SMBJ130A only when layout space is limited and surge threat level is ≤IEC 61000-4-5 Level 2. |
| 1.5KE130A | Same electrical specs and Case 41A package, but supplied in 500-unit boxes (not tape-and-reel); no R suffix | No functional difference; differs only in packaging format and logistics handling | Choose 1.5KE130A for manual prototyping or low-volume builds where reel feeding is unnecessary. |
Compared with SMBJ130A, 1.5KE130ARL4 delivers 2.5× higher surge energy handling in an axial-leaded format ideal for high-reliability industrial power stages; versus 1.5KE130A, it enables automated pick-and-place assembly without changing circuit design or layout.

FAQ
What is the maximum clamping voltage of the 1.5KE130ARL4 under a 1500 W surge?
The 1.5KE130ARL4 clamps to a maximum of 179 V when subjected to its rated 8.4 A peak pulse current (IPP), corresponding to a 1500 W transient per the 1 ms pulse definition in the datasheet. This value is guaranteed across temperature and production lot, and represents the highest voltage seen by downstream components during clamping - critical for verifying margin against IC absolute maximum ratings.
Is the 1.5KE130ARL4 RoHS-compliant and halogen-free?
Yes, the 1.5KE130ARL4 is Pb-free and RoHS-compliant, as confirmed by the "G" suffix in its full manufacturer marking (1.5KE130ARL4G per datasheet page 3). The Surmetic plastic package and lead finish meet JEDEC J-STD-609 Category 1 requirements, and halogen content is below 900 ppm chlorine/bromine per IEC 61249-2-21.
Can the 1.5KE130ARL4 be used in bidirectional protection circuits?
No, the 1.5KE130ARL4 is strictly unidirectional and must be oriented with cathode toward the protected line. For bidirectional protection (e.g., AC lines or symmetric data buses), a dedicated bidirectional variant like 1.5KE130CA or paired unidirectional devices are required - using 1.5KE130ARL4 in reverse bias risks permanent damage due to lack of reverse avalanche capability.
What is the thermal resistance junction-to-lead (RJL) for the 1.5KE130ARL4, and how does it affect layout?
The 1.5KE130ARL4 has a specified thermal resistance of RJL = 20 °C/W, measured from junction to lead at 3/8″ lead length. This means each watt of sustained power dissipates ~20 °C temperature rise at the die - so for its 5.0 W steady-state rating, leads must be thermally anchored (e.g., wide copper pours, multiple vias) to maintain TL ≤ 75 °C and avoid derating.
Does the 1.5KE130ARL4 require a series current-limiting resistor in typical applications?
No, the 1.5KE130ARL4 is designed for direct parallel connection without external current-limiting resistors. Its low dynamic impedance and fast response enable immediate clamping. However, a small series impedance (e.g., ferrite bead or 1–10 Ω) may be added to reduce di/dt-induced overshoot in high-inductance layouts - but this is layout-dependent, not a requirement of the 1.5KE130ARL4 itself.
