Product details
Overview
1N6292ARL4G from ON Semiconductor is a unidirectional 1500 W Mosorb transient voltage suppressor (TVS) diode in axial lead Surmetic package, designed for parallel clamping of high-energy transients. It features a 64.1 V working peak reverse voltage (VRWM), 75 V breakdown voltage (VBR) at 1 mA test current, and clamps to ≤103 V at 14.6 A peak pulse current - protecting power supplies, industrial controls, and communication interfaces against ESD and surge events.
For engineers reviewing the 1N6292ARL4G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, UL 497B-certified loop protection capability, sub-1 ns response time, low zener impedance, and real-world design context for surge immunity validation in DC power rails and signal lines.
Technical Context
The 1N6292ARL4G operates as a unidirectional avalanche diode with sharp reverse-breakdown characteristics, triggered when transient voltage exceeds its 75 V nominal VBR. Its clamping action limits downstream voltage to ≤103 V under 1 ms 14.6 A pulses, enabling robust protection of CMOS/MOS/Bipolar ICs without crowbarring the circuit.
Designed for leaded through-hole mounting, it leverages thermoset plastic encapsulation (Case 41A) with corrosion-resistant, solderable leads rated for 260°C/10 s. Thermal resistance is 20°C/W (junction-to-lead), supporting 5.0 W steady-state dissipation at TL ≤ 75°C with 20 mW/°C derating above that temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 64.1 V - maximum continuous reverse operating voltage before clamping begins; sets minimum system rail margin for safe operation |
| VBR @ IT=1 mA | 71.3–78.8 V - guaranteed avalanche onset range; ensures predictable turn-on during overvoltage events |
| VC @ IPP=14.6 A | ≤103 V - peak clamped voltage under 1 ms surge; defines worst-case stress on protected load |
| PPK | 1500 W @ 1 ms - single-pulse surge handling capacity; validates suitability for IEC 61000-4-5 Level 4 testing |
| IR @ VRWM | ≤5 μA - ultra-low leakage at rated working voltage; prevents excessive standby current in high-impedance circuits |

Applications
| Industrial Power Supply Protection | Telecom Line Interface |
|---|---|
Use Scenario: DC input stage of programmable logic controller (PLC) power module exposed to inductive switching surges and lightning-induced ring waves. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed across +24 V rail and chassis ground to clamp transients before they reach DC-DC converters and microcontrollers. Use Value: Limits voltage excursion to ≤103 V during 14.6 A surges, preserving 3.3 V/5 V logic supply integrity and preventing brownout resets or latch-up in downstream ASICs. | Use Scenario: RS-485 data line termination in building automation gateway, subject to induced surges from nearby AC mains and relay switching. IC Role / Device Role / Timing Role: Parallel-connected TVS on differential pair (A/B) referenced to local ground, absorbing common-mode transients while maintaining signal integrity. Use Value: Clamps fast-rising ESD events (<1 ns) without adding significant capacitance (measured at VRWM), avoiding data rate degradation on 10 Mbps links. |
| Medical Equipment Input Stage | Process Control Sensor Interface |
Use Scenario: Auxiliary 12 V DC input of patient monitor with external battery charger interface, requiring compliance with IEC 60601-1-2 EMC immunity. IC Role / Device Role / Timing Role: Primary overvoltage protector on main DC input, coordinated with upstream fuse and downstream LC filter to meet surge immunity Class B. Use Value: UL 497B recognition confirms suitability for medical isolated loop applications, and 16 kV HBM rating exceeds IEC 61000-4-2 Level 4 requirements. | Use Scenario: 4–20 mA current loop transmitter connected to hazardous-area field devices via intrinsically safe barriers. IC Role / Device Role / Timing Role: Transient suppressor on barrier output side, limiting fault voltage to safe levels during lightning-induced ground potential rise. Use Value: 64.1 V VRWM aligns with 24 V loop supply headroom, and 1500 W PPK withstands multiple 1 ms surges per IEC 61000-4-5 without parameter shift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1.5KE75A | Same VBR (75 V), identical Case 41A package, but non-Pb-free and supplied in bulk (AG) vs. tape-and-reel (ARL4G) | No UL 497B listing; lacks formal isolated loop certification | Select when RoHS compliance is not required and volume procurement favors bulk packaging |
| SMBJ75A | Surface-mount SMB package, same 75 V VBR, lower PPK (600 W), higher IR (5 μA vs. 1 μA typical) | Not suitable for high-energy 1500 W surges; limited to board-level ESD near ICs | Choose for space-constrained designs where 1 ms surge energy is below 600 W and automated SMT assembly is preferred |
Compared with 1.5KE75A, the 1N6292ARL4G adds Pb-free compliance and UL 497B certification for isolated loop use; compared with SMBJ75A, it delivers triple the surge power handling and axial through-hole reliability for high-stress front-end protection - making it optimal for industrial power entry points.

FAQ
What is the clamping voltage of the 1N6292ARL4G under maximum rated surge current?
The 1N6292ARL4G clamps to a maximum of 103 V when subjected to its rated 14.6 A peak pulse current (IPP) with a 1 ms waveform. This value is measured per Figure 5 in the ON Semiconductor datasheet and represents the worst-case voltage seen by downstream components during surge events - a key parameter for ensuring protected ICs remain within absolute maximum ratings.
Is the 1N6292ARL4G RoHS compliant and what does the 'G' suffix indicate?
Yes, the 1N6292ARL4G is RoHS compliant. The 'G' suffix explicitly denotes a Pb-free package per ON Semiconductor's standard designation, confirmed in the ordering information table and mechanical characteristics section of the datasheet. This applies to both the Surmetic axial lead construction and lead finish, meeting EU Directive 2011/65/EU requirements without exemptions.
Does the 1N6292ARL4G have UL recognition and for which standard?
Yes, the 1N6292ARL4G carries UL recognition under standard UL 497B (File #E210057, category QVGQ2) for protectors in isolated loop circuits. This certification covers performance tests including strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge - going beyond basic flammability compliance to validate functional safety in telecom and industrial isolation applications.
What is the maximum steady-state power dissipation for the 1N6292ARL4G and how is it derated?
The 1N6292ARL4G has a steady-state power dissipation (PD) rating of 5.0 W at lead temperature (TL) ≤ 75°C, with linear derating of 20 mW/°C above that temperature. This thermal limit is defined in the Maximum Ratings table and must be respected in continuous-duty applications such as DC bias protection - unlike its 1500 W peak pulse rating, which applies only to non-repetitive 1 ms transients.
How does the 1N6292ARL4G compare to bidirectional TVS diodes in surge protection applications?
The 1N6292ARL4G is unidirectional and optimized for DC-biased lines where reverse polarity is fixed - e.g., +24 V power rails referenced to ground. Unlike bidirectional TVS diodes, it avoids unnecessary conduction during normal negative excursions and provides tighter clamping (lower VC/VBR ratio) in the intended direction. For AC or floating signals, a bidirectional device would be required, but for most industrial DC power and signal interfaces, the 1N6292ARL4G offers superior efficiency and precision.
