Product details
Overview
ICTE-5RL4 from onsemi is a unidirectional 1500 W peak power TVS diode designed for transient voltage suppression in DC power rails and signal lines. It features a 5.0 V working peak reverse voltage (VRWM), 9.4 V clamping voltage at 160 A peak pulse current, <1 ns response time, and low leakage (<300 µA at VRWM). It is used to protect CMOS/MOS/Bipolar ICs in power supplies and industrial control systems.
For engineers reviewing the ICTE-5RL4 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin vs. protected circuit's absolute maximum rating, surge current capability under 1 ms pulse, thermal derating above 75°C lead temperature, and axial-leaded mounting compatibility with legacy through-hole PCB layouts.
Technical Context
This device operates as a Zener-based avalanche clamp, triggered when reverse voltage exceeds its 6.0–7.5 V breakdown range (VBR @ IT = 1 A). Its low dynamic impedance and sub-nanosecond turn-on enable effective suppression of ESD (Class 3, >16 kV HBM) and lightning-induced surges.
Rated for 1500 W nonrepetitive peak power at TA = 25°C and derated linearly above TL = 75°C (20 mW/°C), it delivers 5.0 W steady-state dissipation with 3/8″ lead length. Thermal resistance junction-to-lead is 20°C/W, supporting reliable operation up to +175°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W @ 1 ms - sustains single high-energy transients without failure |
| Working Peak Reverse Voltage (VRWM) | 5.0 V - sets minimum operating voltage threshold before clamping begins |
| Clamping Voltage (VC) | 9.4 V @ IPP = 160 A - limits maximum voltage seen by protected IC during surge |
| Breakdown Voltage (VBR) | 6.0–7.5 V @ IT = 1 A - defines precise avalanche initiation point for design margining |
| Response Time | <1 ns - ensures clamping activation prior to damage in fast-rising transients |
| Leakage Current | <300 µA @ VRWM - minimizes standby power loss in low-current systems |
| ESD Rating | Class 3 (>16 kV HBM) - meets IEC 61000-4-2 Level 4 immunity requirements |
Pinout & Package
ICTE-5RL4 uses an axial-leaded Surmetic plastic package (Case 41A), with cathode identified by a polarity band. Leads are solderable per 260°C/10 s standard, and mounting position is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased operation | Connected to system ground or lower-potential rail in unidirectional clamp configuration |
| Cathode | High-side terminal with polarity band marking | Connected to protected line; conducts avalanche current to ground during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping architecture | Enables precise protection of positive-rail circuits without forward conduction interference |
| 1500 W peak pulse rating | Supports IEC 61000-4-5 4 kV surge testing with margin for system-level robustness |
| Low zener impedance | Maintains stable clamping voltage across wide current range (1–160 A), reducing overshoot risk |
| Pb-Free axial package (RoHS compliant) | Meets global environmental compliance without sacrificing thermal or mechanical reliability |
| –65°C to +175°C operating range | Validates use in automotive under-hood, industrial motor drives, and outdoor power equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A | Surface-mount SMB package; 600 W peak power; 9.2 V clamping @ 62.5 A | Lower surge capacity; requires PCB redesign for SMT placement and reflow | Preferred where board space is constrained and surge levels are ≤600 W |
| 1N6373RL4 | Same electrical specs and Case 41A package; JEDEC-marked variant of ICTE-5RL4 | No functional or layout difference; identical pinout and thermal behavior | Drop-in replacement with same sourcing channel and qualification history |
Compared with SMBJ5.0A, ICTE-5RL4 offers 2.5× higher surge rating and axial-leaded compatibility with legacy through-hole designs; compared with 1N6373RL4, ICTE-5RL4 shares identical performance but uses ON Semiconductor's proprietary device coding and traceability structure.

FAQ
What is the clamping voltage of ICTE-5RL4 at its rated peak pulse current?
The ICTE-5RL4 has a maximum clamping voltage (VC) of 9.4 V when subjected to its rated peak pulse current 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 surge events. The ICTE-5RL4 maintains this clamping performance across its specified temperature range and is validated per IEC 61000-4-5 test conditions.
Is ICTE-5RL4 RoHS compliant and lead-free?
Yes, ICTE-5RL4 is supplied in a Pb-Free (RoHS-compliant) axial package per the "G" suffix designation in the ordering information. The leads are readily solderable at 260°C for 10 seconds at 1/16″ from the case, and all external surfaces meet corrosion resistance requirements. ICTE-5RL4 conforms to JEDEC standards for lead-free termination and is documented in onsemi's Pb-Free packaging reference manual.
Can ICTE-5RL4 be used in bidirectional configurations?
No, ICTE-5RL4 is a unidirectional TVS diode and must be connected with cathode toward the protected line and anode to ground. It does not provide symmetrical clamping for AC or dual-rail applications. For bidirectional protection, separate devices or dedicated bidirectional TVS arrays (e.g., P6SMB6.8CA) are required. The ICTE-5RL4 datasheet explicitly specifies unidirectional operation and polarity band marking.
What is the maximum steady-state power dissipation for ICTE-5RL4?
The ICTE-5RL4 has a steady-state power dissipation (PD) rating of 5.0 W at lead temperature (TL) ≤ 75°C with 3/8″ lead length. Above 75°C, it derates at 20 mW/°C. This rating applies only to continuous DC or low-frequency conditions-not surge events-and assumes proper PCB thermal relief and ambient airflow. The ICTE-5RL4's 20°C/W junction-to-lead thermal resistance supports this dissipation profile.
How does ICTE-5RL4 compare to 1N6373 in terms of electrical performance?
ICTE-5RL4 and 1N6373 share identical electrical specifications-including VRWM = 5.0 V, VBR = 6.0–7.5 V, VC = 9.4 V @ 160 A, and 1500 W peak power-as confirmed in the same datasheet revision. They differ only in marking convention (ON Semiconductor's ICTE-xx vs. JEDEC's 1N63xx) and traceability coding. The ICTE-5RL4 is functionally interchangeable with 1N6373RL4 in all applications.
