Product details
Overview
1N6292ARL4 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 surges. It features a 64.1 V working peak reverse voltage (VRWM), 75 V breakdown voltage (VBR) at 1 mA, 103 V maximum clamping voltage (VC) at 14.6 A peak pulse current (IPP), and sub-1 ns response time. It is used in industrial power supplies and communication interfaces to safeguard CMOS/MOS ICs from ESD and lightning-induced transients.
For engineers reviewing the 1N6292ARL4 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin relative to protected circuit's absolute maximum rating, VRWM alignment with DC bus voltage, surge current capability under 1 ms pulse, and UL 497B recognition for isolated loop protection compliance.
Technical Context
This device operates as a voltage-clamping avalanche diode, entering low-impedance conduction when reverse voltage exceeds its specified VBR. Its 1500 W peak power rating applies to a non-repetitive 1 ms exponential pulse per Figure 5, with derating above 25°C ambient or 75°C lead temperature per Figures 1 and 2.
It exhibits low zener impedance and fast turn-on due to optimized junction design, enabling effective suppression of fast-rising transients (<1 ns typical response). The unidirectional configuration provides protection only against reverse-polarity surges, requiring correct cathode-anode orientation in-circuit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W @ 1 ms pulse - sustains single high-energy surges without failure |
| Working Peak Reverse Voltage (VRWM) | 64.1 V - maximum continuous reverse voltage before significant leakage; sets minimum operating voltage margin |
| Breakdown Voltage (VBR) | 75 V @ 1 mA - voltage at which avalanche conduction begins; defines clamping onset threshold |
| Clamping Voltage (VC) | 103 V @ 14.6 A IPP - maximum voltage seen by protected circuit during rated surge |
| Leakage Current (IR) | <5 µA @ 64.1 V - negligible standby power loss and signal interference in normal operation |
| Response Time | <1 ns - ensures clamping activation before transient energy damages downstream ICs |
| ESD Rating | Class 3 (>16 kV HBM) - meets stringent electrostatic discharge immunity requirements |
Pinout & Package
1N6292ARL4 is housed in an axial-leaded Surmetic plastic package (Case 41A), with cathode identified by a polarity band. Leads are Pb-free, solderable up to 230°C for 10 seconds at 1/16 inch from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased operation | Connected to system ground or low-side return path; defines clamping reference point |
| Cathode | Protected line connection | Connected to the line being protected (e.g., DC input rail); conducts surge current to ground when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| UL 497B Recognition | Qualified for isolated loop circuit protection - enables use in telecom and industrial safety-critical interfaces without additional certification burden |
| Low Clamping Ratio (VC/VBR) | 103 V / 75 V = 1.37 - tight voltage control minimizes overvoltage stress on protected ICs |
| Pb-Free Lead Finish | Compliant with RoHS and JEDEC J-STD-020 - supports lead-free reflow and hand-soldering processes |
| High Surge Current Capability | 14.6 A peak pulse current - handles IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge waveforms |
| Thermal Resistance (Junction-to-Lead) | 20 °C/W - enables efficient heat dissipation through leads during transient events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | Surface-mount SMB package; 75 V VBR; 100 V VC @ 15.3 A; 600 W rating | Limited to lower-energy transients; unsuitable for 1500 W IEC 61000-4-5 Level 4 | Select when board space is constrained and surge requirements are ≤600 W |
| 1.5KE75A | Same die in alternate packaging (DO-201AE); identical electrical specs; tape-and-reel not offered in RLL4 variant | No functional difference; differs only in packaging format and reel compatibility | Choose for manual assembly or when 1500-unit tape-and-reel is not required |
Compared with SMBJ75A, 1N6292ARL4 delivers 2.5× higher surge power handling and axial-leaded robustness for high-vibration environments; compared with 1.5KE75A, it offers identical protection performance but in a tape-and-reel format optimized for automated insertion.

FAQ
What is the clamping voltage of the 1N6292ARL4 at its rated peak pulse current?
The 1N6292ARL4 has a maximum clamping voltage (VC) of 103 V when subjected to its rated peak pulse current (IPP) of 14.6 A under a 1 ms exponential waveform. This value is measured per the test conditions defined in the ON Semiconductor datasheet and represents the highest voltage the protected circuit will experience during a full-rated surge event. Designers must ensure this clamping level remains below the absolute maximum voltage rating of downstream components.
Is the 1N6292ARL4 suitable for bidirectional transient protection?
No, the 1N6292ARL4 is a unidirectional TVS diode and provides protection only against reverse-polarity transients. It does not conduct in forward bias beyond its ~3.5 V forward voltage drop and cannot suppress positive-going surges on grounded lines. For bidirectional protection, ON Semiconductor offers the 1.5KE75CA series, which uses a different internal structure and carries a "CA" suffix.
Does the 1N6292ARL4 meet UL 497B requirements?
Yes, the 1N6292ARL4 is UL Recognized under file #116110 for protector classification QVGV2 per UL 497B. This certification covers isolation loop circuit protection and confirms successful completion of tests including strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge performance - making it suitable for telecom and industrial safety-critical applications.
What is the thermal resistance specification for the 1N6292ARL4?
The 1N6292ARL4 has a junction-to-lead thermal resistance (RJL) of 20 °C/W, measured under standard test conditions. This parameter quantifies how effectively heat generated during transient conduction transfers from the silicon junction to the external leads, directly influencing safe surge repetition rate and steady-state power handling capability when mounted with proper lead length and thermal mass.
How does the 1N6292ARL4 differ from the 1.5KE75A in terms of electrical performance?
The 1N6292ARL4 and 1.5KE75A share identical electrical specifications - both have 64.1 V VRWM, 75 V VBR, 103 V VC at 14.6 A, and 1500 W peak power rating. They originate from the same ON Semiconductor Mosorb platform and JEDEC-registered die. The distinction lies solely in packaging format and ordering code: 1N6292ARL4 denotes axial-leaded tape-and-reel (1500 units), whereas 1.5KE75A refers to the same device in bulk box packaging.
