Product details
Overview
ICTE-022G 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 22 V working peak reverse voltage with 37.5 A peak pulse current and 29.8 V clamping voltage. It protects CMOS, MOS, and bipolar ICs in power supplies and industrial control systems.
For engineers reviewing the ICTE-022G datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM = 22 V, VC = 29.8 V @ IPP = 37.5 A, response time < 1 ns, low leakage (<2 µA @ VRWM), and axial leaded Case 41A mechanical compatibility for through-hole PCB mounting.
Technical Context
The ICTE-022G operates as a Zener-based avalanche diode TVS, leveraging unidirectional breakdown behavior to shunt transient energy away from sensitive circuit nodes. Its clamping action begins at VBR = 25.9 V (min) @ IT = 1.0 A and stabilizes at VC = 29.8 V under 37.5 A 1 ms pulse stress.
Thermal design relies on RJL = 20 °C/W junction-to-lead resistance and steady-state PD = 5.0 W @ TL ≤ 75°C, with derating above that temperature. The device exhibits ESD robustness >16 kV HBM and forward surge capability of 200 A (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 22 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min) | 25.9 V @ IT = 1.0 A - guaranteed avalanche onset threshold for reliable protection margin |
| VC @ IPP | 29.8 V @ 37.5 A, 1 ms - peak clamped voltage seen by protected circuit during worst-case surge |
| PPK | 1500 W - non-repetitive transient energy absorption capacity per IEC 61000-4-5 waveform |
| Response Time | < 1 ns - enables suppression of fast-rising ESD and lightning-induced transients |
| Leakage Current | < 2 µA @ 22 V - negligible standby power loss and signal integrity impact in DC-biased rails |
| ESD Rating | Class 3 (>16 kV) HBM - meets stringent electrostatic discharge immunity requirements |
Pinout & Package
ICTE-022G uses axial-leaded Case 41A plastic package (Surmetic), with cathode identified by a polarity band. Leads are solderable at 230°C for 10 seconds at 1/16″ from case. Mounting position is unrestricted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| Industrial Power Supply Protection | Medical Equipment Input Stage |
|---|---|
Use Scenario: 24 V DC input rail in programmable logic controller (PLC) power module exposed to inductive switching surges from relay coils and solenoids. IC Role / Device Role / Timing Role: Unidirectional TVS placed across input terminals to clamp transients before they reach upstream rectifier and downstream DC-DC controller. Use Value: Limits voltage excursion to ≤29.8 V during 37.5 A surge, preventing latch-up or gate oxide damage in 30 V-rated MOSFETs and controllers. | Use Scenario: Patient-connected auxiliary power input in diagnostic imaging equipment where EMI immunity must exceed IEC 60601-1 requirements. IC Role / Device Role / Timing Role: Primary overvoltage guard on isolated 24 V auxiliary supply, coordinated with secondary-side TVS and common-mode chokes. Use Value: Delivers >16 kV HBM ESD protection and sub-1 ns response to suppress fast transients from nearby RF sources without adding capacitance-induced signal distortion. |
| Communication System DC Feeds | Process Control Sensor Interface |
Use Scenario: 24 V PoE-powered remote radio head (RRH) base station receiving power over long cable runs susceptible to lightning-induced surges. IC Role / Device Role / Timing Role: First-line transient suppressor at DC input connector, ahead of DC-DC converters and Ethernet PHY power conditioning. Use Value: Absorbs 1500 W peak energy without degradation, maintaining VRWM = 22 V compatibility with 24 V nominal rail and 10% tolerance. | Use Scenario: 4–20 mA loop-powered pressure transmitter installed in chemical plant with frequent electrostatic discharges from pneumatic actuators. IC Role / Device Role / Timing Role: Bidirectional protection is not required; ICTE-022G provides unidirectional clamping on loop supply line referenced to local earth. Use Value: Achieves <2 µA leakage at 22 V, preserving loop accuracy and avoiding false zero-shift errors in precision 4–20 mA output stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22A | Surface-mount SMB package (vs. axial Case 41A); same VRWM = 22 V, but lower PPK = 600 W | Requires PCB rework for SMT layout; unsuitable for high-energy 1500 W surge environments | Select only if space-constrained designs accept reduced surge rating and can guarantee <600 W transient exposure |
| 1N6379G | Same family, JEDEC-registered part; identical electrical specs and Case 41A package; differs only in marking code | No functional or mechanical difference; fully interchangeable in through-hole assembly and thermal management | Preferred for legacy BOM alignment where JEDEC nomenclature is mandated by procurement policy |
Compared with SMBJ22A and 1N6379G, ICTE-022G delivers identical clamping performance and axial mechanical fit as 1N6379G but offers no surface-mount alternative; its 1500 W rating exceeds SMBJ22A by 2.5×, making it mandatory for industrial-grade surge immunity where waveform compliance is verified per IEC 61000-4-5.

FAQ
What is the clamping voltage of ICTE-022G at its rated peak pulse current?
The ICTE-022G has a maximum clamping voltage (VC) of 29.8 V when subjected to its rated peak pulse current (IPP) of 37.5 A under a 1 ms exponential waveform. This value is measured per Figure 5 in the official ON Semiconductor datasheet and defines the upper voltage limit imposed on protected circuits during surge events. The ICTE-022G maintains this clamping performance consistently across its qualified temperature range.
Is ICTE-022G compatible with lead-free soldering processes?
Yes, ICTE-022G is offered in a Pb-free axial package (indicated by the "G" suffix) and is qualified for lead-free wave and hand soldering at 230°C for 10 seconds at 1/16″ from the case body. Its Surmetic plastic encapsulation and lead finish meet J-STD-020 moisture sensitivity level 1 requirements, eliminating pre-bake needs. The ICTE-022G's thermal resistance and power derating curves remain valid under Pb-free reflow profiles.
How does ICTE-022G differ from bidirectional TVS diodes like ICTE-22C?
The ICTE-022G is unidirectional and functions only during reverse-bias overvoltage conditions, making it ideal for DC rails with defined polarity. In contrast, ICTE-22C is bidirectional and clamps both positive and negative transients-suitable for AC lines or floating signals. The ICTE-022G exhibits lower leakage (<2 µA @ 22 V) than ICTE-22C and cannot protect against reverse-polarity faults, so correct orientation during PCB placement is essential for ICTE-022G.
Can ICTE-022G be used in parallel to increase surge current handling?
No, ICTE-022G should not be paralleled without external balancing resistors due to manufacturing tolerances in VBR (±5% typical). Mismatched breakdown voltages cause uneven current sharing, risking thermal runaway in the lower-VBR unit. For higher current capability, select a single higher-rated device such as ICTE-36G (65.2 A IPP) rather than attempting parallel operation of ICTE-022G units.
What is the maximum steady-state power dissipation for ICTE-022G at 75°C lead temperature?
The ICTE-022G has a steady-state power dissipation (PD) rating of 5.0 W at a lead temperature (TL) of 75°C, with linear derating above that point at 20 mW/°C. This rating assumes 3/8″ lead length and applies to continuous DC or low-frequency AC stress-not transient suppression duty cycles. Exceeding this limit risks permanent parametric shift or catastrophic failure; the ICTE-022G's primary function remains pulsed transient suppression, not continuous power handling.
