onsemi ESD7361XV2T5G

Overview

ESD7361XV2T5G from onsemi is a unidirectional ESD protection diode in SOD−523 package, designed for high-speed data line protection with 0.55 pF max junction capacitance, 16 V working peak reverse voltage, and ±15 kV IEC 61000−4−2 contact ESD immunity. It serves as primary transient suppression at USB 2.0, NFC, and wireless charging interface inputs.

For engineers reviewing the ESD7361XV2T5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage under 8 A (31 V), ultra-low capacitance for signal integrity, AEC−Q101 qualification for automotive interfaces, and SOD−523 footprint compatibility with space-constrained PCB layouts.

Technical Context

This device implements a single-channel unidirectional TVS structure optimized for low-capacitance signal-line protection. Its clamping behavior is characterized using TLP testing (Z₀ = 50 Ω, tₚ = 100 ns), delivering 31 V clamping at 8 A and 34 V at 16 A while maintaining <1 nA leakage at 5 V reverse bias.

The ESD7361XV2T5G operates across −55 °C to +125 °C junction temperature range and meets IEC 61000−4−2 Level 4 (±15 kV contact), IEC 61000−4−4 (40 A EFT), and ISO 10605 (±15 kV, 330 pF/2 kΩ) standards - all verified per onsemi's standardized test methodology.

FAQ

What is the maximum clamping voltage of ESD7361XV2T5G under an 8 A TLP pulse?

The ESD7361XV2T5G exhibits a maximum clamping voltage of 31 V when subjected to an 8 A Transmission Line Pulse (TLP) with Z₀ = 50 Ω and tₚ = 100 ns. This value is measured across the device terminals during the defined averaging window (30–60 ns) and ensures safe voltage limiting for downstream 3.3 V or 5 V interface ICs. The clamping performance is confirmed in the official onsemi datasheet revision 6, page 2.

Is ESD7361XV2T5G qualified for automotive applications?

Yes, ESD7361XV2T5G is AEC−Q101 qualified and PPAP capable, as indicated by its SZ prefix (SZESD7361XV2T5G*). It undergoes stress testing for temperature cycling, humidity, mechanical shock, and ESD robustness per automotive reliability standards. This makes ESD7361XV2T5G suitable for infotainment, ADAS camera links, and body electronics where field failure due to ESD must be eliminated.

What package type does ESD7361XV2T5G use, and what are its dimensions?

ESD7361XV2T5G uses the SOD−523 package (Case 502), measuring 1.0 mm × 0.6 mm × 0.4 mm. Its small outline diode form factor enables placement directly at board edges and connectors. The cathode is marked with a polarity band on terminal 1, and the device is supplied in 8,000-unit tape-and-reel format per the onsemi ordering information table.

Does ESD7361XV2T5G support bidirectional ESD protection?

No, ESD7361XV2T5G is a unidirectional ESD protection diode, configured with cathode (pin 1) and anode (pin 2) for series connection on positive-rail signal lines. It protects against positive transients on the cathode side and negative transients via forward conduction through the PN junction. For true bidirectional protection, two ESD7361XV2T5G devices may be placed in series opposition, though this increases capacitance and footprint.

What is the junction capacitance of ESD7361XV2T5G at 1 MHz and zero bias?

The junction capacitance of ESD7361XV2T5G is specified at 0.55 pF maximum when measured at VR = 0 V and f = 1 MHz. This ultra-low value is maintained up to 1 GHz, enabling use on high-speed interfaces such as USB 2.0 and NFC without compromising signal fidelity. The capacitance vs. frequency curve is documented in Figure 6 of the onsemi datasheet.
