Product details
Overview
1N6375G from ON Semiconductor is a unidirectional 1500 W Mosorb transient voltage suppressor (TVS) diode with 10 V working peak reverse voltage (VRWM), 16.7 A peak pulse current (IPP), 13.7 V clamping voltage (VC) at IPP, and sub-1 ns response time. It protects CMOS/MOS/Bipolar ICs in power supplies, industrial controls, and medical equipment against ESD and lightning-induced surges.
For engineers reviewing the 1N6375G datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM ≥ system DC bus voltage, VC margin relative to IC absolute maximum ratings, surge current capability for IEC 61000-4-5 compliance, and axial leaded package compatibility with through-hole PCB layouts.
Technical Context
The 1N6375G operates as a unidirectional avalanche-clamping TVS diode, triggered when reverse voltage exceeds its 11.7 V minimum breakdown voltage (VBR) at 1 mA test current. Its low dynamic impedance and fast turn-on ensure effective suppression of 8.3 ms half-sine transients up to 16.7 A without thermal runaway.
Designed for parallel protection across sensitive inputs/outputs, it delivers 1500 W peak power dissipation at TL ≤ 25°C with 20 °C/W junction-to-lead thermal resistance. Its Surmetic axial leaded Case 41A package supports manual or wave soldering at 260°C for 10 seconds at 1/16″ from case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; must exceed circuit's steady-state DC or peak AC voltage. |
| VBR @ IT = 1 mA | 11.7–14.1 V - Breakdown threshold range; ensures reliable triggering above normal operating voltage while avoiding false trips. |
| VC @ IPP = 16.7 A | 13.7 V - Clamped voltage during 8.3 ms surge; determines maximum stress on protected downstream ICs. |
| IPP | 16.7 A - Peak pulse current capability at 1 ms; defines surge energy handling per IEC 61000-4-5 Level 4 (4 kV/2 Ω). |
| Response Time | < 1 ns - Enables suppression before transient energy couples into sensitive nodes; critical for high-speed digital interfaces. |
| Leakage Current @ VRWM | < 2.0 μA - Negligible standby power loss and signal integrity impact in always-on monitoring circuits. |
| ESD Rating (HBM) | > 16 kV - Meets Class 3 ESD immunity requirements for end-user accessible ports and connectors. |
Pinout & Package
1N6375G uses an axial-leaded, unidirectional TVS diode package in ON Semiconductor's Surmetic Case 41A (JEDEC TO-204AA equivalent), with cathode identified by a polarity band. Leads are tin-plated copper, corrosion-resistant, and solderable per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current sink path during clamping | Connected to ground or low-impedance return; carries full surge current during overvoltage events. |
| Cathode | Protected line connection point | Connected to the line being protected (e.g., +12 V rail); voltage referenced to anode during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W Peak Pulse Power | Enables robust protection against IEC 61000-4-5 4 kV surge tests without derating or parallel devices. |
| Low Clamping Ratio (VC/VBR ≈ 1.17) | Minimizes voltage overshoot during transients, preserving margin below IC absolute maximum ratings. |
| Pb-Free Axial Package (Case 41A) | Complies with RoHS Directive 2011/65/EU and supports automated through-hole assembly with standard wave solder profiles. |
| Sub-1 ns Response Time | Ensures clamping activation before transient edges propagate into sensitive analog or digital circuitry. |
| ESD >16 kV (HBM) | Provides built-in electrostatic discharge immunity for front-panel interfaces, sensor inputs, and communication lines. |
Applications
| Industrial Power Supply Input Protection | Medical Equipment ESD Shielding |
|---|---|
Use Scenario: Protecting AC/DC converter primary-side rectifier outputs and secondary-side 12 V bias rails from line surges and load dump transients. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed across input rails to clamp transients before they reach PWM controllers, optocouplers, or feedback networks. Use Value: Prevents latch-up or gate oxide damage in MOSFET drivers and error amplifiers by limiting transient voltage to ≤13.7 V. | Use Scenario: Safeguarding patient-connected analog front-ends (e.g., ECG electrode inputs) and USB/RS-232 diagnostic ports against operator ESD. IC Role / Device Role / Timing Role: Low-leakage TVS diode installed at connector entry points to shunt HBM discharges before reaching precision op-amps or ADCs. Use Value: Maintains signal integrity with <2.0 μA leakage at 10 V while suppressing >16 kV contact discharges without affecting baseline offset. |
| Programmable Logic Controller I/O Protection | Automated Test Equipment Signal Lines |
Use Scenario: Hardening 24 V DC digital input modules against field-wiring transients and inductive kickback from solenoid loads. IC Role / Device Role / Timing Role: Standoff TVS connected between input terminal and common rail to absorb repetitive 100 A/10 ms surges from relay switching.

IC Role / Device Role / Timing Role: Ultra-low-capacitance TVS placed directly at SMA/BNC connectors to avoid signal distortion in 100 MHz+ measurement paths. Use Value: Delivers <1 ns response with negligible parasitic capacitance, preserving rise time and amplitude fidelity of fast test pulses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Surface-mount SMB package; 10 V VRWM; 24.4 V VC @ 39.4 A; lower peak power (600 W) | Requires PCB redesign for SMT layout; better suited for space-constrained consumer electronics vs. industrial through-hole assemblies | Select when board area is constrained and surge requirements are ≤ Level 3 (2 kV/12 Ω) |
| 1N6375RLG | Same electrical specs and Case 41A package; tape-and-reel packaging (1500 units/reel) vs. bulk box (500 units/box) for 1N6375G | No functional difference; optimized for automated pick-and-place insertion in high-volume manufacturing | Select for automated assembly lines requiring reel-fed feeders and traceable lot control |
Compared with SMBJ10A and 1N6375RLG, the 1N6375G offers identical transient suppression performance in a Pb-free axial package optimized for manual prototyping, repair, and low-to-mid volume industrial production-without requiring layout changes or sacrificing surge margin.

FAQ
What is the maximum clamping voltage of the 1N6375G during a 16.7 A transient event?
The 1N6375G clamps to a maximum of 13.7 V when subjected to its rated 16.7 A peak pulse current (IPP), measured per Figure 5 waveform (8.3 ms half-sine). This value is guaranteed across temperature and process variation, ensuring protected ICs remain within safe operating voltage limits during surge events.
Is the 1N6375G suitable for bidirectional transient protection?
No, the 1N6375G is a unidirectional TVS diode and only clamps in reverse bias. It must be oriented with cathode toward the protected line and anode to ground. For bidirectional protection (e.g., AC lines or data buses), use a symmetric device like SMAJ10A or a back-to-back pair configuration.
What is the thermal resistance from junction to lead for the 1N6375G?
The 1N6375G has a junction-to-lead thermal resistance (RJL) of 20 °C/W, measured with 3/8″ lead length at TL ≤ 25°C. This enables efficient heat transfer to PCB copper pours or chassis mounts, supporting sustained operation under repetitive surge conditions when properly heatsinked.
Does the 1N6375G meet RoHS and REACH compliance requirements?
Yes, the "G" suffix in 1N6375G explicitly denotes a Pb-free Surmetic axial package compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full material declarations and test reports are available upon request from ON Semiconductor's compliance portal.
Can the 1N6375G replace the older 1N6375 without design changes?
Yes, the 1N6375G is a direct drop-in replacement for the legacy 1N6375, sharing identical electrical specifications, Case 41A mechanical dimensions, and pinout. The "G" suffix indicates only the Pb-free plating upgrade-no PCB layout, schematic, or thermal design modifications are required.
