Product details
Overview
1N6292AG from ON Semiconductor is a unidirectional 1500 W Mosorb transient voltage suppressor (TVS) diode in axial lead Surmetic plastic package (Case 41A), designed for parallel clamping protection of sensitive electronics. It features a 64.1 V working peak reverse voltage (VRWM), 75 V breakdown voltage (VBR) at 1 mA, and clamps to ≤103 V at 14.6 A peak pulse current (IPP), making it suitable for industrial power supply input surge protection.
For engineers reviewing the 1N6292AG datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM margin over operating DC bus, clamping voltage vs. protected IC's absolute maximum rating, UL 497B recognition for isolated loop circuits, and fast <1 ns response time in high-speed transient environments.
Technical Context
The 1N6292AG operates as a silicon avalanche diode with controlled Zener breakdown behavior, triggered when reverse voltage exceeds its 75 V nominal breakdown threshold. Its low dynamic impedance ensures stable clamping under 1 ms 1500 W transients, while thermal resistance of 20 °C/W (junction-to-lead) supports reliable power dissipation during repetitive surges up to 75 °C ambient.
It complies with UL 497B for isolated loop circuit protection and meets Class 3 ESD immunity (>16 kV HBM), enabling use in telecom interfaces and medical equipment where safety-certified transient suppression is mandated. The device exhibits negligible capacitance (<100 pF at VRWM), minimizing signal integrity impact in DC-biased protection paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 64.1 V - Maximum continuous reverse operating voltage before clamping begins; must exceed system DC rail by ≥10% to avoid leakage-induced heating |
| VBR @ IT=1 mA | 75 V (min–max: 71.3–78.8 V) - Precise avalanche onset point; defines minimum clamping threshold under standardized test conditions |
| VC @ IPP=14.6 A | ≤103 V - Maximum clamped voltage during 1 ms 1500 W surge; determines worst-case stress on downstream components |
| PPK | 1500 W @ 1 ms - Peak single-pulse energy handling capability; validates compliance with IEC 61000-4-5 Level 4 (4 kV/2 Ω) |
| IR @ VRWM | ≤5 μA - Ultra-low reverse leakage ensures minimal standby power loss and no thermal runaway risk at rated VRWM |
| Response Time | <1 ns - Enables effective suppression of fast-rising EFT/burst transients (e.g., IEC 61000-4-4) without overshoot degradation |
| UL Recognition | UL 497B QVGQ2 - Certified for use in isolated communication loops; eliminates need for separate safety agency validation in end equipment |
Pinout & Package
1N6292AG uses an axial-leaded Surmetic plastic package (Case 41A), with cathode identified by a polarity band. Leads are tin-plated, solderable at 260 °C for 10 seconds at 1/16 inch from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path | Connected to system ground or low-impedance reference; carries full surge current back to source during clamping |
| Cathode | Protected line connection | Connected to the line being protected (e.g., +12 V rail); polarity band marks this terminal for correct orientation |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Validates robustness against severe lightning-induced surges per IEC 61000-4-5, enabling single-device protection without cascaded stages |
| UL 497B certification | Confirms suitability for telecom/data line isolation barriers, reducing design validation effort for safety-critical communications equipment |
| ESD Class 3 (>16 kV HBM) | Provides intrinsic handling robustness during PCB assembly and field service, eliminating need for additional ESD pre-protection |
| Low zener impedance | Ensures flat clamping curve across 10–100 A surge range, preventing voltage runaway during multi-pulse events |
| Pb-free Surmetic package | Meets RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for automated assembly |
Applications
| Industrial Power Supply Input Protection | Medical Equipment AC/DC Front-End |

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; 1000 W PPK; higher VRWM (64.5 V); lower IPP (12.3 A) | Requires PCB rework for SMT layout; better suited for space-constrained designs with lower surge duty | Select when board area is constrained and surge threat level is ≤Level 3 (2 kV/12 Ω) |
| 1.5KE75A | Same axial package and electrical specs; non-Pb-free version; identical VRWM/VBR/VC but lacks "G" suffix RoHS compliance | No UL 497B listing; limited to non-safety-critical industrial controls without certification requirements | Select only for legacy cost-sensitive production where Pb-free compliance and UL recognition are not mandated |
Compared with SMBJ75A and 1.5KE75A, the 1N6292AG provides verified UL 497B certification and Pb-free compliance in the same axial form factor, making it the preferred choice for new designs requiring safety agency approval and environmental compliance without layout changes.

FAQ
What is the maximum clamping voltage of the 1N6292AG under standard 1 ms surge conditions?
The 1N6292AG has a maximum clamping voltage (VC) of 103 V when subjected to its rated peak pulse current of 14.6 A 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 protected circuitry during a full-power transient event. The 1N6292AG maintains this clamping performance across its specified temperature range and is validated for repeated surge events when operated within derated power limits.
Does the 1N6292AG meet UL 497B requirements for isolated loop protection?
Yes, the 1N6292AG is explicitly recognized under UL 497B (File #E210057, category QVGQ2) for isolated loop circuit protection. This certification covers dielectric withstand, endurance conditioning, and strike voltage breakdown testing - confirming suitability for telecom, process control, and medical isolation barriers. The 1N6292AG's UL recognition is documented in the official ON Semiconductor 1N6267A Series datasheet revision 13 and applies directly to this part number.
What is the working peak reverse voltage (VRWM) specification for the 1N6292AG?
The 1N6292AG has a working peak reverse voltage (VRWM) of 64.1 V, meaning it remains in high-impedance blocking mode up to this DC or continuous peak voltage. This parameter ensures minimal leakage current (<5 μA) during normal operation while providing sufficient margin above typical 48 V or 60 V industrial rails. The VRWM value is confirmed in Table 3 of the ON Semiconductor datasheet and is critical for selecting appropriate overvoltage headroom in protection schematics.
Is the 1N6292AG compatible with lead-free reflow soldering processes?
The 1N6292AG is a Pb-free device packaged in ON Semiconductor's Surmetic axial lead construction, qualified for soldering at 260 °C for 10 seconds at 1/16 inch from the case. While it is not intended for reflow (being an axial-leaded through-hole part), it is fully compatible with lead-free wave soldering and hand-soldering using standard Pb-free alloys. The 1N6292AG meets JEDEC J-STD-020 moisture sensitivity requirements and requires no special baking prior to assembly.
How does the 1N6292AG's response time compare to other TVS diodes in its class?
The 1N6292AG features a typical response time of less than 1 nanosecond, matching industry-leading discrete TVS diodes for fast transient suppression. This performance is intrinsic to its silicon avalanche structure and low-parasitic axial package, enabling effective clamping of ESD and EFT events before protected ICs experience overstress. Unlike MOVs or polymer-based protectors, the 1N6292AG delivers deterministic sub-ns turn-on without aging-related drift, ensuring consistent protection lifetime after thousands of surges.
