Product details
Overview
ICTE-36RL4G from onsemi is a unidirectional 36 V working peak reverse voltage TVS diode in axial Surmetic package, rated for 1500 W peak pulse power at 1 ms, with 50.6 V clamping voltage at 23 A peak pulse current and <1 ns response time. It protects sensitive CMOS/MOS/Bipolar ICs in industrial power supplies and communication interfaces against ESD (>16 kV HBM) and lightning-induced surges.
For engineers reviewing the ICTE-36RL4G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, axial lead terminal roles, real-world protection use cases, and two validated alternative TVS devices with documented parameter differences.
Technical Context
The ICTE-36RL4G operates as a unidirectional transient voltage suppressor, leveraging Zener avalanche breakdown to clamp transients above its 42.4 V minimum breakdown voltage (measured at 1 mA test current). Its low dynamic impedance ensures stable clamping under fast-rising surges.
Designed for parallel connection across protected lines, it delivers sub-nanosecond response and 2.0 mA maximum leakage at VRWM = 36 V. Thermal resistance is 20 °C/W junction-to-lead, supporting reliable operation up to +175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage (VRWM) | 36 V - Maximum continuous DC or peak AC voltage the device blocks without clamping. |
| Peak Pulse Power (PPK) | 1500 W @ 1 ms - Sustains single high-energy transients like IEC 61000-4-5 surge events. |
| Clamping Voltage (VC) | 50.6 V @ 23 A IPP - Limits voltage seen by downstream circuitry during worst-case surge. |
| Breakdown Voltage (VBR) | 42.4 V min @ 1 mA - Threshold where avalanche conduction begins; defines lower bound of clamping window. |
| Response Time | <1 ns - Enables suppression before transient energy damages logic-level ICs or data lines. |
| ESD Rating | Class 3 (>16 kV HBM) - Meets stringent electrostatic discharge immunity requirements for end-equipment certification. |
| Leakage Current (IR) | <2.0 µA @ 36 V - Negligible standby power loss and signal integrity impact in always-on systems. |
Pinout & Package
ICTE-36RL4G 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″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current return path | Connected to ground or low-impedance reference; carries full surge current during clamping. |
| Cathode | Protected line connection point | Connected to the line being protected (e.g., VCC, data line); voltage referenced to anode during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse rating | Supports robust protection against 10/1000 µs lightning surges per IEC 61000-4-5 Level 4. |
| Low clamping ratio (VC/VBR ≈ 1.19) | Minimizes overvoltage stress on protected ICs while maintaining margin above operating voltage. |
| Pb-free Surmetic axial package | Enables RoHS-compliant through-hole assembly with corrosion-resistant, readily solderable leads. |
| −65 °C to +175 °C operating range | Suitable for under-hood automotive modules, industrial motor drives, and outdoor telecom equipment. |
Applications
| Industrial Power Supply Input Protection | RS-485 Data Line Surge Suppression |
|---|---|
Use Scenario: Protecting primary-side rectifier outputs and secondary-side DC rails from load dump and AC line transients. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between rail and ground to clamp overvoltage spikes before reaching DC-DC controllers or microcontrollers. Use Value: Clamps 36 V nominal rails to ≤50.6 V during 1500 W surges, preventing latch-up or gate oxide damage in downstream ICs. |
Use Scenario: Safeguarding differential bus transceivers in factory automation networks exposed to ground potential differences and EFT bursts. IC Role / Device Role / Timing Role: Bidirectional protection not required; ICTE-36RL4G used on VCC-supplied side of isolated RS-485 node to suppress common-mode surges. Use Value: Sub-1 ns response ensures clamping occurs before transceiver input stages experience destructive overvoltage. |
| Medical Equipment AC/DC Adapter Interface | Programmable Logic Controller (PLC) Digital I/O Protection |
Use Scenario: Shielding low-voltage logic circuits in patient-connected devices from mains-borne transients entering via external AC adapters. IC Role / Device Role / Timing Role: TVS mounted at adapter input connector to divert surge energy away from isolated DC-DC converters and microcontroller power domains. Use Value: 16 kV HBM ESD rating and 50.6 V clamping meet IEC 60601-1-2 immunity requirements for applied parts. |
Use Scenario: Hardening 24 V digital input channels in PLC backplanes against field-wiring induced surges and relay coil flyback. IC Role / Device Role / Timing Role: Unidirectional TVS connected between input terminal and chassis ground to absorb positive-going transients on 24 V supply lines. Use Value: 36 V VRWM matches standard 24 V industrial control rails with sufficient margin; 1500 W rating handles repetitive switching noise. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | Surface-mount SMB package; 36 V VRWM; 64.5 V VC @ 23.3 A; 600 W PPK | Requires PCB redesign for SMT placement; lower peak power limits use in high-surge environments | Select when board space is constrained and surge levels are ≤600 W |
| 1N6380RLG | Same axial Surmetic Case 41A package; identical VRWM (36 V), VBR (42.4 V), and VC (50.6 V); same 1500 W rating | No functional or mechanical difference; ON Semiconductor dual-marking variant | Drop-in replacement with identical performance and form factor |
Compared with ICTE-36RL4G, SMBJ36A offers compact SMT integration but sacrifices 40% peak power handling, while 1N6380RLG provides identical protection in the same axial package-making it a seamless second-source option without layout changes.

FAQ
What is the clamping voltage of ICTE-36RL4G at its rated peak pulse current?
The ICTE-36RL4G has a maximum clamping voltage (VC) of 50.6 V when subjected to its rated peak pulse current of 23 A, measured per the 10/1000 µs waveform defined in Figure 5 of the datasheet. This value ensures protected circuits remain below critical overvoltage thresholds during surge events, and it is confirmed in Table 1 under the ICTE-36 row.
Is ICTE-36RL4G unidirectional or bidirectional, and how does that affect its circuit placement?
ICTE-36RL4G is a unidirectional TVS diode, meaning it conducts only when the cathode is biased positively relative to the anode. It must be placed with cathode toward the protected line (e.g., VCC or signal) and anode to ground. This configuration blocks normal operating voltage but clamps positive transients-unlike bidirectional devices, it does not protect against negative excursions.
Does ICTE-36RL4G meet RoHS and lead-free requirements?
Yes, ICTE-36RL4G is supplied in a Pb-free Surmetic axial package, as indicated by the "G" suffix in its ordering code and explicitly stated in the Mechanical Characteristics section. The device complies with RoHS Directive 2011/65/EU and supports lead-free reflow and wave soldering processes per onsemi's Soldering and Mounting Techniques Reference Manual.
What is the maximum steady-state power dissipation for ICTE-36RL4G at 75°C lead temperature?
The ICTE-36RL4G has a steady-state power dissipation (PD) rating of 5.0 W at a lead temperature (TL) of 75°C, with thermal derating of 20 mW/°C above that temperature. This rating applies to continuous DC or low-frequency AC conditions-not transient suppression-and is specified in the Maximum Ratings table on page 2 of the datasheet.
Can ICTE-36RL4G be used in automotive applications?
ICTE-36RL4G supports an operating junction temperature range of −65 °C to +175 °C and is qualified for industrial environments, but it is not AEC-Q200 qualified. While its electrical specs align with many automotive subsystems (e.g., body control modules), onsemi does not list ICTE-36RL4G for automotive-grade use; designers requiring AEC-Q200 compliance should select designated automotive TVS variants.
