Overview
1N6295AG from ON Semiconductor is a unidirectional 1500 W Mosorb transient voltage suppressor (TVS) diode in axial lead Surmetic plastic package, designed for parallel clamping of high-energy transients. It features a 85.5 V working peak reverse voltage (VRWM), 100 V nominal breakdown voltage (VBR), and clamps to 137 V at 11 A peak pulse current (IPP), protecting sensitive CMOS/MOS/Bipolar ICs in power supplies and industrial controls.
For engineers reviewing the 1N6295AG datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, UL 497B certification status, clamping performance at rated surge, thermal derating behavior, and validated alternative TVS devices for circuit protection design.
Technical Context
The 1N6295AG operates as a unidirectional avalanche diode with fast <1 ns response time and low dynamic impedance, enabling effective suppression of ESD and lightning-induced surges per IEC 61000-4-2/4-5. Its 1500 W peak pulse power rating applies to non-repetitive 1 ms pulses at TL ≤ 25°C, with thermal resistance (RJL) of 20°C/W and steady-state power dissipation of 5.0 W at TL ≤ 75°C.
It complies with UL 497B for isolated loop circuit protection and achieves Class 3 ESD immunity (>16 kV HBM). The device exhibits a temperature coefficient of VBR of 0.106 %/°C and maximum reverse leakage of 5 µA at VRWM, ensuring stable clamping across industrial temperature range (−65°C to +175°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 85.5 V - Maximum continuous reverse operating voltage before clamping begins; must be ≥ system DC/peak operating voltage. |
| VBR @ IT=1 A | 100 V (nominal), 95–105 V range - Breakdown initiates reliably within this band at 1 mA test current. |
| VC @ IPP=11 A | 137 V - Clamped voltage during 1500 W transient; defines worst-case overvoltage seen by protected circuit. |
| IPP | 11 A - Peak pulse current corresponding to 1500 W surge at 137 V; used with Figure 5 waveform. |
| IR @ VRWM | ≤5 µA - Negligible leakage ensures minimal standby power loss and no signal distortion in high-impedance lines. |
| Response Time | <1 ns - Enables suppression before transient energy couples into downstream ICs; limited only by PCB layout inductance. |
| UL Recognition | UL 497B (QVGQ2, File #E210057) - Certified for use in isolated loop protectors, not just flammability compliance. |
Pinout & Package
1N6295AG uses an axial-leaded CASE 41A (Surmetic) plastic package with cathode indicated by a polarity band. Leads are solderable per J-STD-020, rated for 260°C for 10 seconds at 1/16″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |

IC Role / Device Role / Timing Role: Reverse-biased clamping element across loop terminals to absorb fault energy from wiring faults or nearby arc events. Use Value: Maintains loop integrity under surge stress due to low leakage and stable VBR (0.106 %/°C), avoiding false trips or calibration drift in SIL-2 systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1.5KE100AG | Same VRWM (85.5 V), identical VBR (100 V), same 137 V clamping at 11 A; Pb-free axial package, identical CASE 41A. | No functional difference; direct manufacturer-recommended alternate with identical marking and packaging format. | Select when sourcing from distributors listing 1.5KE100AG as active stock; electrically and mechanically interchangeable. |
| SMBJ100A | Surface-mount SMB package; lower 600 W peak power; 100 V VBR but 170 V clamping at 3.5 A IPP - higher clamping voltage and lower surge capacity. | Not suitable for 1500 W surge environments; appropriate only for space-constrained designs with lower threat levels (e.g., IEC 61000-4-2 only). | Choose only if board real estate prohibits axial leads and surge requirements are ≤600 W; verify clamping margin with system-level testing. |
Compared with 1N6295AG, 1.5KE100AG offers identical protection performance in the same axial package, while SMBJ100A trades surge capability and clamping tightness for SMT compatibility - making the former a true functional match and the latter a footprint-constrained compromise.

Yes, the 1N6295AG carries UL 497B recognition under File #E210057 and category QVGQ2, specifically certified as a protector for isolated loop circuits. This goes beyond basic flammability testing and validates performance in surge endurance, dielectric withstand, discharge, and strike voltage breakdown tests. UL 497B recognition is critical for medical, telecom, and industrial safety certifications and is explicitly confirmed for the full 1N6267A Series including the 1N6295AG.
What is the maximum reverse leakage current for the 1N6295AG and at what voltage is it specified?
The 1N6295AG has a maximum reverse leakage current (IR) of 5 µA, specified at its working peak reverse voltage (VRWM) of 85.5 V and ambient temperature of 25°C. This low leakage ensures minimal power loss and avoids interference in high-impedance sensing or precision analog circuits. The 1N6295AG maintains this specification across its full industrial temperature range, supporting reliable operation in battery-powered or energy-sensitive applications.
How does the 1N6295AG compare to the 1.5KE100AG in terms of electrical and mechanical compatibility?
The 1N6295AG and 1.5KE100AG are electrically and mechanically identical: both specify VRWM = 85.5 V, VBR = 100 V, VC = 137 V at IPP = 11 A, and use the same CASE 41A axial package with Pb-free finish. They share identical thermal ratings, UL 497B recognition, and marking conventions. The 1.5KE100AG is ON Semiconductor's preferred alternate part number for the 1N6295AG, confirming full interchangeability without design or layout changes required for the 1N6295AG.
