Product details
Overview
1N6290ARL4 from ON Semiconductor is a unidirectional 1500 W Mosorb transient voltage suppressor (TVS) diode designed for parallel clamping protection of sensitive electronics against high-energy transients. It features a 53 V working peak reverse voltage (VRWM), 62 V breakdown voltage (VBR) at 1 mA, and clamps to ≤85 V at 17.7 A peak pulse current (IPP), making it suitable for industrial power supply input stage surge protection.
For engineers reviewing the 1N6290ARL4 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin relative to protected IC maximum ratings, peak pulse current handling under IEC 61000-4-5 waveform, UL 497B recognition for isolated loop circuits, and axial leaded Surmetic package compatibility with through-hole PCB assembly.
Technical Context
This device operates as a voltage-clamping TVS diode in avalanche breakdown mode during transient events, with sub-nanosecond response time (<1 ns) and low dynamic impedance to minimize overshoot. Its unidirectional configuration provides reverse-biased protection only, requiring correct polarity placement across DC rails.
Thermal design relies on junction-to-lead thermal resistance (RJL = 20 °C/W) and derating above 75 °C ambient; steady-state power dissipation is limited to 5.0 W at TL ≤ 75 °C, with 20 mW/°C linear derating beyond that point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W @ 1 ms - withstands IEC 61000-4-5 combination wave surges without failure |
| Working Peak Reverse Voltage | 53 V - maximum continuous DC or peak AC voltage before clamping initiates |
| Breakdown Voltage | 62 V @ 1 mA - precise avalanche onset threshold for predictable clamping behavior |
| Clamping Voltage | ≤85 V @ 17.7 A IPP - limits transient voltage seen by downstream circuitry |
| Leakage Current | <5 µA @ VRWM - negligible standby power loss and signal integrity impact |
| Response Time | <1 ns - fast enough to protect CMOS/MOS devices before damage occurs |
| ESD Rating | Class 3 (>16 kV HBM) - meets stringent electrostatic discharge immunity requirements |
Pinout & Package
Package: Axial-leaded Surmetic plastic case (Case 41A), void-free transfer-molded thermosetting material; cathode indicated by polarity band; leads solderable at 230 °C for 10 seconds at 1/16 inch from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lower-potential rail; defines conduction direction during reverse transient |
| Cathode | High-side transient clamp node | Connected to protected line (e.g., +VIN); conducts avalanche current to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| UL 497B Recognition | Qualified for isolated loop circuit protection - enables use in telecom and industrial interface designs requiring safety certification |
| Low Zener Impedance | Minimizes voltage overshoot during fast transients - critical for protecting 3.3 V or 5 V logic interfaces |
| Pb-Free External Lead Finish | Complies with RoHS Directive 2011/65/EU - supports environmentally compliant manufacturing |
| High Surge Capability | Withstands 200 A forward surge (8.3 ms half-sine) - ensures reliability in mains-connected equipment |
| Stable Temperature Coefficient | 0.104 %/°C VBR drift - maintains clamping accuracy 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 |
|---|---|---|---|
| SMBJ58A | Surface-mount SMB package; 58 V VRWM; 1000 W rating; higher clamping ratio (VC/VBR ≈ 1.45 vs. 1.37) | Requires PCB redesign for SMT layout; better suited for space-constrained consumer electronics | Select when board area is constrained and reflow compatibility is required |
| 1.5KE62A | Same JEDEC-spec 1N6290A family; identical electrical specs; axial leaded but supplied in bulk (500/unit box) not tape-and-reel | No change in circuit function or layout; differs only in packaging format and reel quantity (1500 vs. 500) | Select when tape-and-reel automation is unnecessary and cost-per-unit is prioritized |
Compared with SMBJ58A and 1.5KE62A, the 1N6290ARL4 offers verified tape-and-reel delivery for automated assembly, maintains identical clamping performance to the 1.5KE62A variant, and delivers superior surge robustness (1500 W vs. 1000 W) over SMBJ-series alternatives for heavy-duty industrial use.

FAQ
What is the clamping voltage of the 1N6290ARL4 at its rated peak pulse current?
The 1N6290ARL4 clamps to a maximum of 85 V at its specified peak pulse current of 17.7 A (1 ms exponential decay waveform). This value is measured per Figure 5 in the ON Semiconductor datasheet and represents the upper limit of voltage imposed on protected circuitry during worst-case surge events, ensuring compatibility with 75 V-rated components downstream.
Is the 1N6290ARL4 RoHS-compliant and lead-free?
Yes, the 1N6290ARL4 features a Pb-free external lead finish as explicitly stated in the ON Semiconductor datasheet revision 6. It complies with the EU RoHS Directive 2011/65/EU and is suitable for lead-free soldering processes with a maximum lead temperature of 230 °C for 10 seconds at 1/16 inch from the case.
Does the 1N6290ARL4 have UL 497B recognition?
Yes, the 1N6290ARL4 carries UL 497B recognition under File #116110 for protector classification (QVGV2). This certification covers isolation loop circuit protection and confirms successful completion of strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge testing - exceeding basic flammability-only approvals held by many competitors.
What is the thermal resistance and power derating behavior of the 1N6290ARL4?
The 1N6290ARL4 has a junction-to-lead thermal resistance (RJL) of 20 °C/W. Its steady-state power dissipation is rated at 5.0 W up to 75 °C lead temperature, then derates linearly at 20 mW/°C above that point. This allows accurate thermal modeling in chassis-mounted or heatsink-attached configurations where lead conduction dominates cooling.
How does the 1N6290ARL4 differ from the 1.5KE62A variant?
The 1N6290ARL4 and 1.5KE62A share identical electrical specifications including VRWM (53 V), VBR (62 V), and VC (85 V), as both belong to the same ON Semiconductor Mosorb family. The distinction lies solely in part numbering convention (JEDEC vs. ON proprietary) and packaging: 1N6290ARL4 is supplied in 1500-unit tape-and-reel format, whereas 1.5KE62A is offered in 500-unit bulk boxes.
