Product details
Overview
ICTE-10RL4G from onsemi is a unidirectional 1500 W peak power TVS diode designed to protect voltage-sensitive circuits against high-energy transients. It features a 10 V working peak reverse voltage (VRWM), 16.7 A peak pulse current (IPP), 13.7 V clamping voltage (VC) at IPP, <2 µA leakage at VRWM, and sub-1 ns response time. It is used in industrial power supplies and communication interfaces requiring robust ESD and surge immunity.
For engineers reviewing the ICTE-10RL4G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin relative to system operating voltage, peak pulse current handling under IEC 61000-4-5 surge conditions, thermal derating at elevated lead temperatures, and axial-leaded mechanical compatibility with through-hole PCB layouts.
Technical Context
The ICTE-10RL4G operates as a Zener-based transient voltage suppressor in parallel with protected circuitry, entering avalanche conduction when reverse voltage exceeds its 11.7 V minimum breakdown voltage (VBR @ IT = 1 A). Its low dynamic impedance ensures stable clamping during fast-rising transients up to 1500 W for 1 ms.
It is rated for operation from –65 °C to +175 °C, with thermal resistance of 20 °C/W (junction-to-lead), and supports steady-state dissipation of 5.0 W at TL ≤ 75 °C. The device uses Surmetic axial-leaded plastic packaging (Case 41A) with Pb-free finish and cathode band polarity marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; must exceed system DC/peak AC rail voltage. |
| IPP | 16.7 A - Peak pulse current it can safely shunt during 1 ms transient; defines surge current capacity per IEC 61000-4-5 Level 4. |
| VC @ IPP | 13.7 V - Clamped voltage seen by protected circuit at 16.7 A; determines maximum stress on downstream ICs. |
| VBR @ IT=1A | 11.7–14.1 V - Breakdown voltage range; ensures reliable turn-on without premature conduction during normal operation. |
| IR @ VRWM | <2 µA - Reverse leakage current at 10 V; negligible power loss and no signal integrity impact in high-impedance nodes. |
| Response Time | <1 ns - Time to enter avalanche conduction; critical for suppressing ESD events (IEC 61000-4-2) and fast transients. |
| Package | Case 41A - Axial-leaded plastic package (8.5–9.5 mm length, 4.8–5.3 mm diameter); compatible with standard through-hole assembly and manual rework. |
Pinout & Package
ICTE-10RL4G is a two-terminal unidirectional TVS diode in axial-leaded Case 41A package. Cathode is marked by a colored band; anode is unmarked lead. Leads are tinned, solderable, and rated for 260 °C for 10 seconds at 1/16″ from case.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Surface-mount SMB package (3.5 × 4.6 mm), 1000 W peak power, 17.0 V VC @ 10.8 A | Requires SMT layout; lower peak power and higher clamping voltage than ICTE-10RL4G | Select when board space is constrained and surge severity is moderate (e.g., IEC 61000-4-5 Level 3). |
| 1N6375RLG | Same axial Case 41A package, identical VRWM (10 V), but 1500 W rating and 16.7 A IPP match ICTE-10RL4G exactly | JEDEC-marked variant; functionally identical performance and mechanical fit | Drop-in replacement with identical electrical and mechanical behavior; suitable for legacy design reuse or dual-sourcing. |
Compared with SMBJ10A, ICTE-10RL4G delivers higher surge current headroom and lower clamping voltage in a through-hole package ideal for high-reliability industrial assemblies; compared with 1N6375RLG, ICTE-10RL4G shares identical specifications and packaging but reflects onsemi's proprietary device coding and traceability structure.

FAQ
What is the clamping voltage of ICTE-10RL4G at its rated peak pulse current?
The ICTE-10RL4G has a maximum clamping voltage (VC) of 13.7 V when subjected to its rated peak pulse current of 16.7 A for a 1 ms waveform. This value is measured per Figure 5 in the official datasheet and defines the upper voltage limit imposed on protected circuitry during surge events. Maintaining VC below the absolute maximum ratings of downstream components is essential for reliable protection - the ICTE-10RL4G achieves this while delivering 1500 W peak power handling capability.
Is ICTE-10RL4G suitable for bidirectional transient protection?
No, ICTE-10RL4G is a unidirectional TVS diode optimized for clamping positive transients on grounded systems. Its design assumes cathode connected to the protected line and anode to ground. For bidirectional protection (e.g., AC lines or differential buses), a symmetric device such as P6KE10CA or SMAJ10CA would be required. Using ICTE-10RL4G in reverse-biased configurations risks permanent breakdown due to lack of reverse standoff rating - always verify polarity during placement in schematics and PCB layouts for ICTE-10RL4G.
What is the maximum steady-state power dissipation of ICTE-10RL4G at 75°C lead temperature?
The ICTE-10RL4G is rated for 5.0 W steady-state power dissipation at a lead temperature (TL) of 75 °C, with linear derating above that temperature at 20 mW/°C. This rating applies only to continuous DC or low-frequency reverse bias conditions - not transient events. In typical surge protection use, the device remains idle with <2 µA leakage, so thermal design focuses on transient energy absorption and PCB copper area for heat spreading during rare surge events, not continuous power. Always refer to Figure 4 in the ICTE-10RL4G datasheet for full derating curves.
Does ICTE-10RL4G meet RoHS and REACH compliance requirements?
Yes, ICTE-10RL4G carries the "G" suffix indicating a Pb-free Surmetic package compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The device uses lead-free terminations and halogen-free molding compound. Full material declarations and test reports are available through onsemi's compliance portal. For ICTE-10RL4G, no exemptions apply - it is fully compliant out-of-box for use in consumer, industrial, and medical products sold in regulated markets.
How does ICTE-10RL4G compare to standard 1N400x rectifiers in surge protection roles?
ICTE-10RL4G is not a rectifier - it is a purpose-built Zener-type TVS diode with 1500 W peak power, <1 ns response, and controlled clamping behavior. Standard 1N400x diodes lack specified surge ratings, have slow recovery (>30 µs), and exhibit uncontrolled avalanche characteristics. Using a 1N4007 instead of ICTE-10RL4G in surge protection will likely result in catastrophic failure during IEC 61000-4-2 or -4-5 events. ICTE-10RL4G's guaranteed VC, IPP, and VBR parameters make it a validated solution where 1N400x parts are electrically and physically unsuitable.
