Product details
Overview
1N6292A 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 75 V breakdown voltage (VBR), 103 V maximum clamping voltage (VC) at 14.6 A peak pulse current (IPP), and <1 ns response time - deployed in industrial power supplies, communication interfaces, and medical equipment input stages.
For engineers reviewing the 1N6292A datasheet, pinout, applications, or equivalent options, key selection criteria include working peak reverse voltage (64.1 V), low zener impedance, UL 497B recognition for isolated loop protection, ESD robustness (>16 kV HBM), and axial leaded Case 41A package compatibility with through-hole PCB layouts.
Technical Context
The 1N6292A operates as a unidirectional avalanche diode, entering conduction when reverse voltage exceeds its 71.3–78.8 V breakdown range (VBR @ IT = 1 mA). Its clamping action limits transient-induced voltage to ≤103 V at 14.6 A (1 ms pulse), with thermal resistance of 20 °C/W (junction-to-lead) enabling sustained surge handling under controlled lead temperature conditions.
It exhibits low leakage (<5 µA @ 64.1 V VRWM), fast turn-on (<1 ns), and a temperature coefficient of +0.105 %/°C for VBR. Designed for non-repetitive surge suppression, it complies with UL 497B for isolated loop circuit protection and supports lead-free soldering at 230 °C (10 s, 1/16″ from case).
Key Specifications

|---|---|
Use Scenario: Protects AC/DC converter front-end against line surges and load dump transients in factory automation controllers. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed across DC bus rails (e.g., +24 V to GND) to clamp overvoltage before reaching downstream regulators and microcontrollers. Use Value: Limits transient voltage to ≤103 V, preventing latch-up or gate oxide damage in 3.3 V/5 V logic powered from the same rail. |
Use Scenario: Shields differential data lines in programmable logic controller (PLC) backplane modules from ESD and cable discharge events. IC Role / Device Role / Timing Role: Paired 1N6292A devices (one per line) referenced to common ground, absorbing common-mode surges on A/B bus lines. Use Value: Maintains signal integrity under >16 kV HBM ESD stress while preserving <1 ns response to preserve timing margins in 10 Mbps RS-485 links. |
| Medical Equipment Power Entry Filtering | Process Control Sensor Signal Conditioning |
Use Scenario: Integrated into IEC 60601-1 compliant power entry modules for diagnostic imaging subsystems. IC Role / Device Role / Timing Role: First-stage transient suppressor on primary-side DC input, upstream of Y-capacitors and common-mode chokes. Use Value: UL 497B certification validates safe operation in patient-connected isolated circuits; 1500 W rating handles defibrillator pulse coupling tests. |
Use Scenario: Protects 4–20 mA analog sensor inputs in hazardous-area transmitters exposed to field wiring transients. IC Role / Device Role / Timing Role: Mounted directly at terminal block, clamping induced surges on current-loop wires before precision op-amps and ADCs. Use Value: Low leakage (<5 µA @ 64.1 V) avoids loading the loop; 64.1 V VRWM aligns with 24 V system headroom and SIL-2 functional safety requirements. |
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 SMC package (vs. axial leaded); lower 1000 W peak power; 75 V VBR min 71.3 V | Requires PCB redesign for SMT placement; better suited for space-constrained consumer electronics | Select when board area is limited and reflow compatibility is required; verify thermal relief for 1500 W surge derating |
| 1.5KE75A | Same die, identical electrical specs, alternate ON Semiconductor part number; identical Case 41A package and marking | No functional or mechanical difference; dual-sourcing option within same manufacturing lot | Use for supply chain diversification without design change; shares same UL 497B listing and RoHS compliance |
Compared with SMBJ75A, 1N6292A offers higher surge capacity and through-hole mounting for high-reliability industrial assemblies; compared with 1.5KE75A, it is electrically and mechanically identical but designated under JEDEC 1N6xxxA nomenclature - enabling legacy BOM continuity.

FAQ
What is the clamping voltage of the 1N6292A at its rated peak pulse current?
The 1N6292A 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 Figure 5 in the official ON Semiconductor datasheet and defines the upper voltage limit imposed on protected circuitry during surge events. The 1N6292A maintains this clamping performance across its specified operating temperature range.
Is the 1N6292A suitable for bidirectional transient suppression?
No, the 1N6292A is a unidirectional TVS diode and only conducts in reverse bias to clamp positive transients on the cathode side. For bidirectional protection, ON Semiconductor offers the 1.5KE75CA series (e.g., 1.5KE75CA), which is functionally distinct and not interchangeable with the 1N6292A. Using 1N6292A in a bidirectional configuration risks forward conduction failure or inadequate negative transient suppression.
Does the 1N6292A meet UL 497B requirements for isolated loop protection?
Yes, the 1N6292A is explicitly recognized under UL 497B (File #116110, Category QVGV2) for isolated loop circuit protection. This certification covers testing for strike voltage breakdown, endurance conditioning, dielectric withstand, and discharge performance - confirming its suitability in telecom, process control, and medical isolation barriers where regulatory compliance is mandatory. The 1N6292A carries this rating as part of the full 1N6267A Series.
What is the maximum steady-state power dissipation for the 1N6292A?
The 1N6292A has a steady-state power dissipation (PD) of 5.0 W at lead temperature (TL) ≤ 75 °C with 3/8″ lead length. Above 75 °C, it derates linearly at 20 mW/°C. This rating applies only to continuous DC or low-frequency conditions - not transient suppression duty cycles. For surge events, the device relies on its 1500 W peak pulse rating, not steady-state thermal limits.
Can the 1N6292A be used in lead-free soldering processes?
Yes, the 1N6292A features a Pb-free external lead finish and is qualified for lead-free soldering at 230 °C for 10 seconds (measured 1/16″ from the case). This meets J-STD-020 moisture sensitivity and reflow profile requirements. The device's thermosetting plastic package remains stable under these conditions, and no special pre-bake or handling is required beyond standard MSL-1 handling for axial-leaded components.
