Product details
Overview
ESD7241N2T5G from onsemi is a bi-directional ultra-low capacitance ESD protection diode in X2DFN2 package, rated for 24 V working voltage, <1.0 pF capacitance at 1 MHz, 38 V clamping voltage at 8 A TLP, and ±28 kV IEC61000-4-2 contact ESD protection-designed for RF antenna line protection in wireless handsets.
For engineers reviewing the ESD7241N2T5G datasheet, pinout, applications, or equivalent options, key selection criteria include sub-1 pF capacitance stability over bias, low insertion loss (<0.15 dB @ 1 GHz), tight clamping performance (38 V @ 8 A), and compatibility with high-frequency signal paths requiring minimal signal distortion.
Technical Context
The ESD7241N2T5G employs a silicon avalanche diode structure optimized for bi-directional transient suppression without DC bias dependency. Its capacitance remains linear from 0 to 24 V reverse bias, enabling stable RF impedance matching across operating voltage ranges.
Clamping behavior is characterized using Transmission Line Pulse (TLP) testing per ANSI/ESD STM5.5.1 (Z₀ = 50 Ω, tₚ = 100 ns), delivering verified 38 V clamping at 8 A and 48 V at 16 A-critical for protecting sensitive RF front-end components against fast-rising ESD transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance (CJ) | 0.7 pF @ 1 GHz - ensures negligible RF signal loading in antenna feedlines up to 3 GHz |
| Clamping Voltage (VC) | 38 V @ 8 A TLP - limits voltage seen by protected IC during ESD event to safe level for 24 V-rated RF transceivers |
| Working Voltage (VRWM) | 24 V - matches common RF power amplifier supply rails and USB 3.x VBUS levels |
| ESD Rating | ±28 kV contact per IEC61000-4-2 - exceeds Level 4 immunity requirement for handheld consumer devices |
| Insertion Loss | 0.15 dB @ 1 GHz - preserves signal integrity in LTE/5G antenna paths with minimal attenuation |
| Leakage Current (IR) | <0.5 µA @ 24 V - avoids DC loading of high-impedance RF detector or tuner inputs |
| Package | X2DFN2 (1.00 × 0.60 × 0.37 mm, 0.65 mm pitch) - enables placement directly at connector or antenna feedpoint with minimal parasitic inductance |
Pinout & Package
X2DFN2 is a 2-terminal, bottom-wettable, leadless DFN package with exposed thermal pad. Dimensions: 1.00 mm × 0.60 mm × 0.37 mm, 0.65 mm pin pitch. Optimized for high-frequency layout with symmetric geometry and minimal trace inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode / Cathode (Bi-directional) | Terminal A of symmetrical avalanche junction - connects to signal line (e.g., antenna feed); no polarity sensitivity |
| Pin 2 | Cathode / Anode (Bi-directional) | Terminal B of symmetrical avalanche junction - connects to ground reference; forms low-inductance path to GND plane |
Key Features
| Feature | Design Value |
|---|---|

| IEC61000-4-2 Level 4 compliance | ±28 kV contact discharge - meets highest ESD immunity tier for consumer wireless terminals |
| Low dynamic resistance | 0.84 Ω (TLP) - enables rapid clamping response with minimal voltage overshoot during sub-nanosecond ESD events |
| Wettable flank compatible | Non-applicable for ESD7241N2T5G (X2DFN2); SZESD7241MXWT5G variant uses X2DFNW2 - supports AOI inspection for automotive-grade builds |

FAQ
What is the maximum working voltage rating for ESD7241N2T5G?
The ESD7241N2T5G has a specified working peak reverse voltage (VRWM) of 24 V, confirmed in the Electrical Characteristics table under TA = 25°C conditions. This rating defines the maximum continuous DC or RMS voltage the device can withstand without significant leakage or degradation, making it suitable for 24 V RF power amplifier supply lines and USB 3.x VBUS applications. The ESD7241N2T5G maintains stable performance up to this voltage threshold.
Does ESD7241N2T5G support bi-directional ESD protection?
Yes, the ESD7241N2T5G is explicitly designed as a bi-directional ESD protection diode, with symmetrical IV characteristics verified in Figures 11 and 12 of the datasheet. It provides identical clamping performance from Pin 1 to Pin 2 and Pin 2 to Pin 1, enabling placement in AC-coupled or floating RF signal paths without polarity concerns. This symmetry is integral to the ESD7241N2T5G's function in antenna feedline protection.
What is the typical capacitance of ESD7241N2T5G at 1 GHz?
The typical junction capacitance of ESD7241N2T5G is 0.7 pF at 1 GHz and 0 V bias, as stated in the Electrical Characteristics table. This ultra-low value is measured under RF-relevant conditions and reflects the device's optimized design for minimal signal loading in high-frequency applications such as LTE and 5G antenna paths. The ESD7241N2T5G maintains this low capacitance across its operational voltage range.
How does ESD7241N2T5G perform under IEC61000-4-2 ESD testing?
The ESD7241N2T5G achieves ±28 kV contact discharge per IEC61000-4-2 Level 4, as documented in both the Features and Maximum Ratings sections. This performance is validated using the standard 150 pF/330 Ω network and correlates with its 38 V clamping voltage at 8 A TLP current. The ESD7241N2T5G reliably suppresses fast-rising ESD transients without failure or parameter shift across multiple stress cycles.
Is ESD7241N2T5G RoHS compliant and lead-free?
Yes, ESD7241N2T5G is Pb-free, halogen/BFR-free, and RoHS compliant, as explicitly stated in the Features section of the datasheet. The "G" suffix in the part number denotes RoHS-compliant packaging, and the device meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for surface-mount assembly. All manufacturing and material declarations for ESD7241N2T5G align with current environmental compliance standards.
