Product details
Overview
VBUS053CZ-HAF-G-08 from Vishay Semiconductors is a 7-pin ultra-compact ESD protection diode array for USB-OTG bus ports, integrating three 5.5 V data-line protectors (D+, D−, ID) and one 28 V VBUS line protector in a single LLP75-7L package. It delivers ±15 kV IEC 61000-4-2 contact/air ESD immunity on data lines, ±30 kV on VBUS, 0.7 pF typical line capacitance, and clamps transients to ≤18 V at 3 A on data lines and ≤52 V at 3 A on VBUS-enabling robust protection in space-constrained mobile charging circuits.
For engineers reviewing the VBUS053CZ-HAF-G-08 datasheet, VBUS053CZ-HAF-G-08 pinout, VBUS053CZ-HAF-G-08 application, or VBUS053CZ-HAF-G-08 equivalent, this device supports high-speed USB signal integrity while meeting stringent automotive infotainment and portable electronics ESD compliance requirements without compromising layout density.
Technical Context
The VBUS053CZ-HAF-G-08 employs a dual-die construction: one die integrates three symmetrical low-capacitance PN diodes for D+, D−, and ID lines (5.5 V working range), and a second dedicated avalanche diode protects the VBUS line (28 V working range). This architecture ensures >40 dB isolation between VBUS and data lines, preventing cross-coupling during surge events.
Each data line exhibits 0.35–0.5 pF line-to-line capacitance and ≤0.1 pF symmetry mismatch, preserving USB 2.0 signal integrity. The VBUS path provides 31–40 pF capacitance and 32–40 V reverse breakdown, enabling fast clamping (<30 ns) to <52 V at 3 A per IEC 61000-4-5.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Single-die 3-line array; no dedicated VBUS path; 5.5 V VRWM only; 1.0 pF typical capacitance | Lacks 28 V VBUS protection-requires external TVS for power rail | Choose when system already includes discrete VBUS protection and board space allows separate components |
| ESD56201D05 | Monolithic 4-channel device with shared VBUS/data clamping; 28 V VRWM on all channels; 1.2 pF capacitance | Higher capacitance degrades USB 2.0 signal integrity above 240 MHz | Prefer for cost-sensitive designs where 480 Mbps throughput is not required |
Compared with TPD2E001DRYR and ESD56201D05, the VBUS053CZ-HAF-G-08 uniquely combines isolated VBUS and data protection in one ultra-low-capacitance package-enabling full USB-OTG compliance without signal integrity trade-offs or secondary protection components.

FAQ
What is the maximum operating temperature for the VBUS053CZ-HAF-G-08?
The VBUS053CZ-HAF-G-08 has a junction temperature range of −40 °C to +125 °C, making it suitable for deployment in sealed consumer electronics enclosures and under-hood automotive modules where thermal dissipation is constrained. Its LLP75-7L package maintains electrical performance stability across this full range, and the device remains fully functional at 125 °C ambient when mounted on standard FR-4 with recommended pad layout.
Does the VBUS053CZ-HAF-G-08 support USB 2.0 high-speed data rates?
Yes, the VBUS053CZ-HAF-G-08 supports USB 2.0 high-speed (480 Mbps) operation due to its 0.7 pF typical line capacitance and 0.1 pF line-to-line capacitance mismatch, which preserve signal integrity and minimize eye diagram closure. Measured clamping response time is <30 ns, ensuring transients are suppressed before data sampling windows are compromised-verified in Vishay's application note AN85200.
How is pin assignment handled for D+, D−, and ID on the VBUS053CZ-HAF-G-08?
The VBUS053CZ-HAF-G-08 features symmetrical pins 1, 2, and 3-any of the three data signals (D+, D−, or ID) can be assigned to any of these pins without affecting electrical performance. This flexibility simplifies PCB routing and eliminates orientation constraints during assembly, as confirmed in the "Remark" section of the official datasheet (Document Number: 85200, Rev. 1.7).
What is the clamping voltage of the VBUS053CZ-HAF-G-08 under a 3 A IEC 61000-4-5 surge?
Under a 3 A IEC 61000-4-5 (8/20 μs) surge, the VBUS053CZ-HAF-G-08 clamps the VBUS line (pin 6 to pin 7) to 42–52 V, and the data lines (pins 1–3 to pin 7) to 15–18 V. These values are specified in the Absolute Maximum Ratings and Electrical Characteristics tables of the official Vishay datasheet, ensuring predictable voltage limiting during real-world surge events.
Is the VBUS053CZ-HAF-G-08 compatible with lead-free reflow processes?
Yes, the VBUS053CZ-HAF-G-08 uses e4 termination (NiPdAu) and is qualified for lead-free reflow with a peak temperature of up to 260 °C per J-STD-020 MSL level 1 guidelines. Its LLP75-7L package withstands standard Pb-free thermal profiles without delamination or solder joint reliability degradation, and Vishay confirms full compliance in the Package Data section of document 85200.
