Product details
Overview
SZESD7241MXWT5G from onsemi is a bi-directional ESD protection diode in a wettable flank X2DFNW2 package, featuring ultra-low 0.7 pF capacitance at 1 GHz, 38 V clamping voltage at 8 A TLP, and ±28 kV IEC61000-4-2 contact ESD rating - designed for RF antenna line protection in wireless handsets.
For engineers reviewing the SZESD7241MXWT5G datasheet, pinout, applications, or equivalent options, key selection criteria include RF insertion loss (<0.15 dB @ 1 GHz), capacitance linearity over bias voltage, wettable flank AOI compatibility, and AEC-Q101 qualification for automotive-grade signal integrity.
Technical Context
The SZESD7241MXWT5G employs a silicon avalanche diode structure optimized for bi-directional transient suppression with symmetrical IV characteristics (VBR = 24.3–28 V, IT = 1 mA). Its junction capacitance remains stable from 0 V to 24 V bias, enabling minimal RF signal distortion in high-frequency paths.
Clamping behavior is characterized using Transmission Line Pulse (TLP) testing per ANSI/ESD STM5.5.1 (Z0 = 50 Ω, tp = 100 ns), delivering 38 V clamping at 8 A and 48 V at 16 A - critical for protecting sensitive RF front-end ICs without degrading impedance matching.

|---|---|
| Capacitance @ 1 GHz | 0.7 pF - enables minimal RF signal attenuation in 5G/4G antenna lines |
| Clamping Voltage @ 8 A TLP | 38 V - limits transient overvoltage to safe levels for GaAs/GaN RFICs |
| Working Reverse Voltage | 24 V - supports common RF power amplifier supply rails and bias networks |
| ESD Rating (IEC61000-4-2) | ±28 kV contact - exceeds Level 4 immunity for handheld device interfaces |
| Insertion Loss @ 1 GHz | 0.15 dB - preserves antenna efficiency and return loss in compact layouts |
| Dynamic Resistance | 0.84 Ω - ensures fast turn-on and low-voltage overshoot during ESD events |

FAQ
What is the clamping voltage specification for SZESD7241MXWT5G under real-world ESD conditions?
The SZESD7241MXWT5G delivers 38 V clamping voltage at 8 A TLP (transmission line pulse) per ANSI/ESD STM5.5.1, and 48 V at 16 A. These values reflect actual measured voltage across the device during standardized ESD surge events, ensuring reliable protection for RF front-end components without exceeding safe voltage thresholds. The SZESD7241MXWT5G maintains this performance symmetrically for both polarities.
Does SZESD7241MXWT5G support automated optical inspection (AOI) in high-reliability manufacturing?
Yes - the SZESD7241MXWT5G uses the X2DFNW2 package with wettable flank side walls, explicitly designed for full-solder-joint visibility under AOI systems. This feature enables 100% solder fillet inspection in automotive and medical-grade assembly lines, satisfying IPC-A-610 Class 3 requirements. The "W" in MXWT5G denotes this wettable flank capability.
Is SZESD7241MXWT5G qualified for automotive applications?
Yes - the SZESD7241MXWT5G carries the "SZ" prefix indicating AEC-Q101 qualification and PPAP capability. It has been tested per automotive stress standards including temperature cycling, humidity bias, and mechanical shock, and is approved for use in telematics, infotainment, and V2X antenna modules where zero-defect reliability is mandated.
How does the capacitance of SZESD7241MXWT5G behave across operating voltage?
The SZESD7241MXWT5G exhibits industry-leading capacitance linearity: junction capacitance stays within 0.7–1.0 pF from 0 V to 24 V reverse bias (measured at 1 MHz and 1 GHz). This stability prevents detuning of RF matching networks and ensures consistent insertion loss across varying DC bias conditions in antenna and NFC circuits.
What is the maximum peak pulse current rating for SZESD7241MXWT5G?
The SZESD7241MXWT5G is rated for 3 A maximum peak pulse current (IPP) under an 8/20 µs lightning waveform per IEC61000-4-5. For ESD events, it withstands ±28 kV contact discharge (IEC61000-4-2) and 40 A EFT bursts (IEC61000-4-4), with clamping validated up to 16 A TLP - confirming robust transient handling in real-world surge environments.
