Product details
Overview
ICTE-36RL4 from onsemi is a unidirectional transient voltage suppressor (TVS) diode in axial-leaded Surmetic plastic package, designed for parallel clamping protection of sensitive electronics. It features 36 V working peak reverse voltage (VRWM), 65.2 A peak pulse current (IPP), 50.6 V clamping voltage (VC) at IPP, <2.0 µA reverse leakage at VRWM, and sub-1 ns response time. It is used in industrial power supplies and communication interfaces to safeguard CMOS/MOS/Bipolar ICs against ESD and lightning-induced surges.
For engineers reviewing the ICTE-36RL4 datasheet, pinout, applications, or equivalent options, key selection criteria include verified clamping performance at 65.2 A, thermal derating behavior above 75°C lead temperature, Pb-free axial package compatibility with wave soldering at 260°C/10 s, and Class 3 (>16 kV HBM) ESD rating - all critical for robust overvoltage protection design.
Technical Context
This device operates as a Zener-based avalanche clamp, triggered when transient voltage exceeds its 42.4 V minimum breakdown voltage (VBR) at 1 mA test current. Its low dynamic impedance and fast turn-on enable effective suppression of 8.3 ms half-sine or square-wave surges up to 1500 W peak power.
Thermal management relies on junction-to-lead resistance of 20 °C/W and steady-state power dissipation of 5.0 W at TL ≤ 75°C, with linear derating above that temperature. Polarity is marked by cathode band; mounting orientation is unrestricted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 36 V - maximum continuous reverse operating voltage before clamping begins |
| IPP | 65.2 A - peak pulse current supported at 1 ms pulse width without failure |
| VC @ IPP | 50.6 V - maximum clamped voltage seen by protected circuit during 65.2 A surge |
| VBR @ IT=1 mA | 42.4 V min - guaranteed avalanche initiation threshold under standardized test |
| IR @ VRWM | <2.0 µA - negligible standby leakage ensuring minimal power loss in high-impedance circuits |
| Response Time | <1 ns - enables suppression before transient energy couples into downstream ICs |
| ESD Rating | Class 3 (>16 kV HBM) - meets IEC 61000-4-2 Level 4 immunity requirements |
Pinout & Package
ICTE-36RL4 uses an axial-leaded CASE 41A package (Surmetic thermosetting plastic), with cathode identified by a colored band. Leads are corrosion-resistant and readily solderable; maximum soldering temperature is 260°C at 1/16″ from case for 10 seconds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to system ground or lower-potential rail in unidirectional clamp configuration |
| Cathode | Current exit point during reverse-biased clamping | Connected to protected line (e.g., data bus, power rail); polarity band identifies this terminal |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Enables single-device protection against IEC 61000-4-5 10/700 µs surges up to 4 A on 50 Ω lines |
| Low clamping ratio (VC/VBR ≈ 1.19) | Minimizes overvoltage stress on protected ICs relative to breakdown threshold |
| Pb-Free axial package (RoHS compliant) | Supports automated wave soldering and eliminates lead contamination risk in end equipment |
| −65°C to +175°C operating range | Validates use in industrial environments with wide ambient and self-heating variations |
| Void-free molded construction | Ensures mechanical reliability and moisture resistance in humid or thermally cycled applications |
Applications

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 DO-214AA package; 36 V VRWM; 64.5 A IPP; 58.1 V VC - higher clamping voltage than ICTE-36RL4 | Requires PCB rework for SMT assembly; unsuitable for through-hole legacy designs or high-power axial layouts | Select when board space is constrained and automated pick-and-place is available |
| 1N6380RLG | Same manufacturer, identical electrical specs (36 V VRWM, 65.2 A IPP, 50.6 V VC), but in 500-unit box packaging instead of tape-and-reel | No functional difference; differs only in logistics format - not suitable for high-speed automated placement | Choose for manual prototyping or low-volume production where reel feeding is unnecessary |
Compared with SMBJ36A and 1N6380RLG, ICTE-36RL4 offers the lowest clamping voltage (50.6 V) among these 36 V-rated TVS options and is uniquely optimized for axial-leaded, high-reliability industrial assemblies requiring wave-solder compatibility and extended thermal margin.

FAQ
What is the maximum clamping voltage of ICTE-36RL4 at its rated peak pulse current?
The ICTE-36RL4 has a maximum clamping voltage (VC) of 50.6 V at its rated peak pulse current (IPP) of 65.2 A, measured per the 1 ms exponential waveform defined in Figure 5 of the datasheet. This value ensures predictable overvoltage limiting during standardized surge events and is validated across the full operating temperature range.
Is ICTE-36RL4 compatible with lead-free wave soldering processes?
Yes, ICTE-36RL4 is Pb-free and qualified for wave soldering at 260°C for 10 seconds at a distance of 1/16″ from the case body. Its Surmetic plastic package and corrosion-resistant leads meet IPC-J-STD-020 moisture sensitivity and thermal endurance requirements for RoHS-compliant manufacturing.
How does the thermal derating of ICTE-36RL4 affect its steady-state power handling?
ICTE-36RL4 delivers 5.0 W steady-state power dissipation at lead temperature (TL) ≤ 75°C, with linear derating of 20 mW/°C above that point. At TL = 100°C, its usable power drops to 4.5 W - a critical consideration when mounted near heat-generating components or in enclosed enclosures without forced airflow.
Can ICTE-36RL4 be used in bidirectional protection configurations?
No, ICTE-36RL4 is a unidirectional TVS diode and must be used with correct polarity: cathode to the protected line, anode to ground. For bidirectional protection, two ICTE-36RL4 devices would need back-to-back connection, or a dedicated bidirectional part like P6SMB36CA should be selected instead.
What is the breakdown voltage tolerance of ICTE-36RL4 at 1 mA test current?
The ICTE-36RL4 has a minimum breakdown voltage (VBR) of 42.4 V and a maximum of 47.1 V at IT = 1 mA and TA = 25°C, corresponding to a ±5% tolerance around the nominal 45 V VBR. This tight distribution ensures consistent clamping onset across production lots and supports reliable system-level surge margin calculations.
