Product details
Overview
ICTE-10RL4 from onsemi is a unidirectional 1500 W peak power TVS diode in axial leaded Surmetic package, rated for 10 V working peak reverse voltage (VRWM), 16.7 A peak pulse current (IPP), and clamping voltage of 13.7 V at IPP. It features <1 ns response time, <2 µA leakage at VRWM, and ESD rating >16 kV per HBM - deployed to protect power supplies and industrial control inputs against lightning-induced surges.
For engineers reviewing the ICTE-10RL4 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin vs. protected IC VDD, surge current capability under 8.3 ms waveform, thermal derating above 75°C lead temperature, and axial lead soldering compatibility with IPC-J-STD-001 Class 3 requirements.
Technical Context
This device operates as a voltage-clamping transient suppressor placed in parallel with sensitive circuit nodes. Its silicon avalanche structure delivers low dynamic impedance (<1 Ω typical) and stable breakdown voltage (11.7–14.1 V) across temperature, enabling predictable overvoltage protection during fast-rising transients up to 1500 W.
Designed for non-repetitive surge events, ICTE-10RL4 follows JEDEC-standard 1N63xx series specifications with 20 °C/W junction-to-lead thermal resistance and 200 A forward surge rating. It requires external series impedance (Zin) to limit peak current and must be mounted with minimal lead length to suppress inductive overshoot.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W @ 1 ms - sustains single lightning surge without failure |
| Working Peak Reverse Voltage (VRWM) | 10 V - maximum continuous DC/peak AC voltage before conduction |
| Clamping Voltage (VC) @ IPP | 13.7 V @ 16.7 A - limits transient voltage seen by downstream ICs |
| Breakdown Voltage (VBR) | 11.7–14.1 V @ 1 mA - defines onset of avalanche conduction |
| Response Time | <1 ns - ensures clamping activation before most IC damage thresholds |
| ESD Rating (HBM) | >16 kV - exceeds IEC 61000-4-2 Level 4 immunity requirement |
| Leakage Current @ VRWM | <2 µA - negligible standby power loss in always-on circuits |
Pinout & Package
ICTE-10RL4 uses axial-leaded CASE 41A (Surmetic) plastic package with cathode indicated by polarity band. Leads are tin-plated, solderable at 260°C for 10 seconds at 1/16″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink during transient clamp | Connected to ground or low-impedance return path to complete clamping loop |
| Cathode | Protected line connection point | Connected to input rail (e.g., +12 V supply) requiring surge suppression |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping | Protects positive-polarity rails only; blocks reverse leakage below VRWM |
| Low zener impedance | Ensures stable VC under varying IPP - critical for consistent IC-level voltage limiting |
| Pb-free Surmetic package | RoHS-compliant axial construction with corrosion-resistant finish and verified solderability |
| Thermal robustness | RJL = 20 °C/W enables operation up to +175°C junction temperature with proper lead heatsinking |
| Fast transient response | <1 ns turn-on minimizes voltage overshoot before clamping engages |
Applications
| Industrial Power Supply Input Protection | PLC Digital Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Surface-mount DO-214AA package; 1000 W peak power; 17.0 V clamping @ 52.2 A | Requires PCB rework for SMT layout; higher VC reduces margin for 12 V systems | Select when board space is constrained and thermal management supports SMT mounting |
| 1N6375RL4G | Same axial CASE 41A package; identical VRWM (10 V); 16.7 A IPP; 13.7 V VC - functionally identical | No change in mechanical fit, soldering process, or electrical behavior | Valid second-source option with same onsemi manufacturing and qualification |
Compared with SMBJ10A and 1N6375RL4G, ICTE-10RL4 offers axial-leaded through-hole compatibility for legacy industrial designs, lower clamping voltage than SMBJ10A for tighter 12 V rail margins, and full equivalency to 1N6375RL4G in form, fit, and function - making it optimal for high-reliability through-hole surge protection where leaded assembly remains standard.

FAQ
What is the maximum clamping voltage of ICTE-10RL4 under surge conditions?
The ICTE-10RL4 has a maximum clamping voltage (VC) of 13.7 V when subjected to its rated peak pulse current of 16.7 A, measured per Figure 5 waveform (8.3 ms half-sine). This value is guaranteed across temperature and ensures protected circuits remain below critical overvoltage thresholds. The ICTE-10RL4 datasheet specifies this parameter under standardized test conditions to enable accurate system-level surge margin analysis.
Is ICTE-10RL4 compatible with lead-free soldering processes?
Yes, ICTE-10RL4 is supplied in a Pb-free Surmetic axial package (indicated by the "G" suffix) and qualified for lead-free reflow and hand-soldering. Its leads withstand 260°C for 10 seconds at 1/16″ from the case, meeting IPC-J-STD-001 requirements. The ICTE-10RL4's thermosetting plastic body and corrosion-resistant finish ensure reliability under repeated thermal cycling in RoHS-compliant manufacturing.
How does ICTE-10RL4 differ from bidirectional TVS diodes like P6KE10CA?
ICTE-10RL4 is unidirectional and protects only positive-polarity transients on DC rails, offering lower leakage (<2 µA) and tighter clamping (13.7 V) than bidirectional equivalents. P6KE10CA clamps both polarities but exhibits higher capacitance and ~20% higher VC. For 12 V DC systems where reverse voltage is absent, ICTE-10RL4 provides superior precision and efficiency - a key distinction confirmed in the ICTE-10RL4 specification table.
Can ICTE-10RL4 be used in parallel to increase surge current handling?
No - ICTE-10RL4 is not characterized for parallel operation due to mismatch in dynamic impedance and avalanche turn-on characteristics. Uneven current sharing may cause thermal runaway in one device. System-level surge handling should be increased via staged protection (e.g., gas discharge tube + ICTE-10RL4) or by selecting a higher-power variant like ICTE-15RL4. This limitation is inherent to the ICTE-10RL4's discrete Zener structure and is not addressed in its application notes.
What is the thermal resistance specification for ICTE-10RL4, and how does it affect PCB layout?
ICTE-10RL4 has a junction-to-lead thermal resistance (RJL) of 20 °C/W, meaning each watt dissipated raises junction temperature 20°C above lead temperature. To maintain reliability, leads must be kept ≤75°C - achieved by using ≥3/8″ lead length, wide copper pours, or thermal vias. This RJL value is measured per the ICTE-10RL4 datasheet's thermal test condition and directly informs heatsinking decisions in high-duty-cycle surge environments.
