Product details
Overview
ICTE-015G from ON Semiconductor is a unidirectional 1500 W peak power Mosorb Zener transient voltage suppressor in axial leaded Surmetic plastic package (Case 41A), designed to clamp high-energy transients at 15 V working peak reverse voltage with 20.1 V clamping voltage at 25 A peak pulse current. It protects CMOS/MOS/Bipolar ICs in power supplies and industrial controls.
For engineers reviewing the ICTE-015G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, axial package dimensions, clamping behavior under 1 ms surge, ESD Class 3 compliance, and real-world protection circuit layout guidance.
Technical Context
The ICTE-015G operates as a unidirectional Zener-based TVS diode with 15 V VRWM and 17.6 V minimum breakdown voltage at 1 mA test current. Its 20.1 V clamping voltage at 25 A IPP ensures robust overvoltage protection for sensitive downstream components.
It features <1 ns response time, low zener impedance, and thermal resistance of 20 °C/W junction-to-lead. The device is rated for −65 °C to +175 °C operating temperature and supports Pb-free soldering at 230 °C for 10 seconds at 1/16″ from case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V - maximum continuous reverse operating voltage before clamping begins |
| IPP @ 1 ms | 25 A - peak pulse current capability at 1 ms waveform, enabling 1500 W transient absorption |
| VC @ IPP | 20.1 V - clamped voltage seen by protected circuit during 25 A surge, limiting stress on downstream ICs |
| VBR min/max | 17.6 V / 20.6 V - breakdown range at 1 mA, ensuring predictable turn-on threshold |
| IR @ VRWM | 2.0 µA - ultra-low leakage at rated working voltage, minimizing standby power loss |
| Response time | <1 ns - enables suppression before fast transients damage logic or analog inputs |
| ESD rating | Class 3 (>16 kV HBM) - meets stringent electrostatic discharge immunity requirements |
Pinout & Package

|---|---|
Use Scenario: 24 V DC input stage of programmable logic controller (PLC) power module exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed across input rails to clamp positive transients before they reach upstream rectifier and downstream DC-DC controller. Use Value: 20.1 V clamping at 25 A prevents overvoltage damage to 30 V-rated MOSFETs and 24 V-rated supervisor ICs during 1500 W surge events. | Use Scenario: Patient-connected sensor interface board in diagnostic imaging equipment requiring IEC 60601-1 compliance. IC Role / Device Role / Timing Role: Primary overvoltage protector on isolated 5 V auxiliary supply rail feeding analog front-end amplifiers and ADCs. Use Value: Class 3 ESD rating (>16 kV HBM) and sub-1 ns response ensure immunity to handling-induced discharges without signal path distortion. |
| Communication System Interfaces | Process Control Signal Lines |
Use Scenario: RS-485 transceiver bus lines in factory automation network subjected to lightning-induced ground potential rise. IC Role / Device Role / Timing Role: Line-side TVS on differential pair, referenced to local ground, absorbing common-mode surges before transceiver ESD structures. Use Value: 15 V VRWM matches typical RS-485 common-mode range; 20.1 V VC avoids false triggering while maintaining 2.5 V margin below transceiver absolute max rating. | Use Scenario: 4–20 mA current loop transmitter output driving remote valve actuators in hazardous area control cabinets. IC Role / Device Role / Timing Role: Bidirectional protection not required; ICTE-015G used on loop supply side to absorb positive-going transients induced by relay coil de-energization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6377, G | Identical electrical specs (VRWM = 15 V, VC = 20.1 V @ 25 A), same Case 41A package, JEDEC-standard marking | No functional difference; differs only in industry-standard JEDEC designation vs. ON Semiconductor's ICTE prefix | Select 1N6377, G when JEDEC-compliant part numbering is required for BOM standardization or legacy design continuity |
| MPTE-15, G | Same VRWM, VC, IPP, and package; identical internal die and construction per ON Semiconductor documentation | No application difference; MPTE series shares same Mosorb technology and qualification data as ICTE series | Choose MPTE-15, G for procurement flexibility where distributor stock of MPTE variants exceeds ICTE availability |
Compared with 1N6377, G and MPTE-15, G, the ICTE-015G offers identical transient suppression performance and thermal behavior but uses ON Semiconductor's proprietary device coding - making it suitable for designs specifying ICTE-series branding or aligned with ON's internal product roadmap.

FAQ
What is the clamping voltage of ICTE-015G at its rated peak pulse current?
The ICTE-015G has a clamping voltage (VC) of 20.1 V at 25 A peak pulse current (IPP) with a 1 ms waveform. This value is measured per Figure 5 in the official ON Semiconductor datasheet and defines the maximum voltage imposed on the protected circuit during a full-rated transient event. The ICTE-015G maintains this clamping performance across its qualified temperature range.
Is ICTE-015G unidirectional or bidirectional, and how does that affect circuit placement?
The ICTE-015G is a unidirectional TVS diode, meaning it conducts only during positive transients relative to its cathode. It must be placed with cathode toward the protected line and anode to ground. This configuration blocks reverse leakage under normal operation while providing low-impedance shunt path for positive surges. The ICTE-015G is not suitable for AC or bipolar signal lines without additional circuitry.
What package type and dimensions does ICTE-015G use?
The ICTE-015G uses Case 41A - an axial-leaded, void-free, thermosetting plastic package measuring 8.5–9.5 mm in length (A) and 4.8–5.3 mm in diameter (B). Lead diameter and finish are uncontrolled per specification, but leads are corrosion-resistant and compatible with Pb-free soldering at 230 °C for 10 seconds at 1/16″ from the case. The ICTE-015G polarity band identifies the cathode end.
Does ICTE-015G meet RoHS and lead-free assembly requirements?
Yes, the ICTE-015G is offered in a Pb-free Surmetic package (indicated by the "G" suffix) and complies with EU RoHS Directive 2011/65/EU. Its leads are readily solderable using standard Pb-free reflow or hand-soldering profiles, with maximum recommended soldering temperature of 230 °C for 10 seconds at 1/16″ from the case. The ICTE-015G's construction eliminates hazardous substances without sacrificing surge capability or thermal performance.
How does ICTE-015G compare to standard 1.5KE series TVS diodes?
The ICTE-015G shares the same 1500 W peak power rating and 15 V VRWM as the 1.5KE15A, but differs in construction: ICTE-015G uses ON Semiconductor's proprietary Mosorb Zener technology in axial Case 41A, whereas 1.5KE devices use DO-201AE packages. The ICTE-015G offers lower dynamic impedance and tighter VBR tolerance than generic 1.5KE parts, and is qualified to higher reliability standards for industrial use. Both protect similarly, but ICTE-015G is optimized for long-life, high-stress deployments.
