Product details
Overview
ICTE-5RL4G from onsemi is a unidirectional 1500 W peak power TVS diode with 5.0 V working peak reverse voltage (VRWM), 9.4 V clamping voltage (VC) at 160 A peak pulse current (IPP), and sub-1 ns response time. It protects CMOS/MOS/Bipolar ICs in power supplies, medical equipment, and industrial controls against ESD (>16 kV HBM) and lightning-induced transients.
For engineers reviewing the ICTE-5RL4G datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM matching system DC bias, VC margin relative to IC absolute maximum ratings, surge current capability under IEC 61000-4-5 waveforms, and axial leaded Surmetic package compatibility with through-hole PCB layouts.
Technical Context
This device operates as a voltage-clamping transient suppressor placed in parallel with protected circuitry. Its low zener impedance and fast turn-on (<1 ns) enable effective suppression of 8/20 µs surges up to 160 A while maintaining clamping below 9.4 V at rated IPP.
The axial leaded CASE 41A package supports lead temperature up to 260°C for 10 seconds during soldering, with cathode polarity marked by a band. Thermal resistance junction-to-lead is 20°C/W, enabling dissipation of 5.0 W steady-state power at TL ≤ 75°C with 3/8″ lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 5.0 V - Maximum continuous reverse operating voltage before clamping begins; must exceed circuit's DC or peak AC bias. |
| VC @ IPP | 9.4 V @ 160 A - Clamped voltage during 1 ms 1500 W surge; defines upper voltage limit seen by protected IC. |
| IPP | 160 A - Peak pulse current capability at 1 ms; validates compliance with IEC 61000-4-5 Level 4 (4 kV) when combined with series impedance. |
| Response Time | <1 ns - Enables suppression before transient energy couples into sensitive nodes; critical for high-speed digital interfaces. |
| IR @ VRWM | <300 µA - Low leakage ensures minimal standby power loss and no signal distortion in high-impedance sensing paths. |
| ESD Rating | Class 3 (>16 kV HBM) - Confirms robustness against human-body model discharges common in handling and assembly. |
| Package | CASE 41A axial lead - Pb-free Surmetic plastic housing with corrosion-resistant leads; compatible with wave and hand soldering. |
Pinout & Package
ICTE-5RL4G uses an axial-leaded CASE 41A package with two terminals: Anode (unmarked end) and Cathode (end marked with polarity band). Leads are tinned copper, solderable per J-STD-001, and rated for 260°C for 10 s at 1/16″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to ground or low-impedance return path in unidirectional TVS configuration. |
| Cathode | Current exit point during reverse clamping | Connected to protected line (e.g., VCC, data line); polarity band identifies this terminal. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power | Supports single-event surge immunity per IEC 61000-4-5 up to 4 kV with appropriate series impedance. |
| Low clamping ratio (VC/VRWM = 1.88) | Minimizes overvoltage stress on downstream ICs compared to higher-ratio TVS devices. |
| Pb-free Surmetic package | Meets RoHS Directive 2011/65/EU and supports lead-free manufacturing without reflow profile compromise. |
| Steady-state power rating | 5.0 W at TL ≤ 75°C enables reliable operation in enclosed power supply enclosures with limited airflow. |
| Fast response <1 ns | Reduces overshoot in high-dI/dt transients, preserving timing margins in microcontroller reset lines and sensor inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A | Surface-mount SMB package; 600 W peak power; 9.2 V VC @ 65 A IPP | Lower surge rating and SMT-only mounting; unsuitable for high-energy 1500 W requirements | Select only if board space constraints prohibit axial leads and surge energy is ≤600 W |
| 1N6373RL4G | Same electrical specs and CASE 41A package; JEDEC-marked version of ICTE-5RL4G | No functional difference; identical performance and footprint | Direct form-fit-function replacement with same sourcing and qualification history |
Compared with SMBJ5.0A, ICTE-5RL4G delivers 2.5× higher surge energy handling in a through-hole package, while 1N6373RL4G offers identical protection in JEDEC-compliant marking-making it the preferred drop-in alternative where legacy part numbering is required.

FAQ
What is the clamping voltage of ICTE-5RL4G at its rated peak pulse current?
The ICTE-5RL4G has a maximum clamping voltage (VC) of 9.4 V at its rated peak pulse current (IPP) of 160 A, measured under the 1 ms exponential waveform defined in Figure 5 of the datasheet. This value ensures protected circuits remain within safe operating limits during high-energy transients. The ICTE-5RL4G maintains this clamping performance across its specified temperature range and lifetime.
Is ICTE-5RL4G suitable for bidirectional transient protection?
No, ICTE-5RL4G is a unidirectional TVS diode optimized for clamping positive transients on grounded lines. For bidirectional protection, two ICTE-5RL4G devices must be connected in series opposition, or a dedicated bidirectional part such as P6SMB5.0CA should be selected. Using ICTE-5RL4G alone on floating or AC-coupled lines risks forward conduction failure.
What is the maximum steady-state power dissipation for ICTE-5RL4G?
The ICTE-5RL4G is rated for 5.0 W steady-state power dissipation at a lead temperature (TL) of ≤75°C with 3/8″ lead length. Power must be derated linearly above 75°C at 20 mW/°C, reaching zero at TL = 325°C. This rating assumes proper PCB thermal relief and adequate airflow in the final application.
Does ICTE-5RL4G meet RoHS and REACH requirements?
Yes, ICTE-5RL4G carries the "G" suffix indicating full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Its Pb-free Surmetic plastic package contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE, and all materials are fully traceable per onsemi's substance compliance declarations.
How does ICTE-5RL4G compare to standard Zener diodes for transient suppression?
Unlike general-purpose Zener diodes, ICTE-5RL4G is specifically designed for transient suppression with 1500 W peak power rating, <1 ns response time, and guaranteed clamping performance at high IPP. Standard Zeners lack surge-rated construction and exhibit inconsistent clamping under fast transients, making ICTE-5RL4G the validated choice for IEC 61000-4-5 compliance.
