Product details
Overview
ESDZV5H-1BU2 from STMicroelectronics is a bidirectional single-line TVS diode designed for I/O port ESD protection in space-constrained portable electronics. It delivers 10 V clamping voltage at 8 kV contact discharge (IEC 61000-4-2), 4 pF typical line capacitance, and 5.5 V stand-off voltage - enabling robust ±30 kV air / ±14 kV contact ESD immunity in 0201 package.
For engineers reviewing the ESDZV5H-1BU2 datasheet, ESDZV5H-1BU2 pinout, ESDZV5H-1BU2 application, or ESDZV5H-1BU2 equivalent, key selection criteria include ultra-low clamping voltage under fast transients, sub-5 pF capacitance for high-speed data lines, bidirectional symmetry, holding voltage margin above system rail, and ECOPACK2-compliant 0201 footprint compatibility.
Technical Context
This device employs a snapback-triggered silicon avalanche structure optimized for low-capacitance, low-clamping ESD suppression. Its symmetrical bidirectional behavior ensures identical protection for positive and negative transients without polarity dependency, while the 5.9 V maximum holding voltage guarantees reliable turn-off after transient decay.
Designed for IEC 61000-4-2 Level 4 compliance, it sustains 4 A peak pulse current (8/20 µs) with dynamic resistance of 0.18 Ω, enabling rapid energy diversion before downstream IC damage. The 0201 ST0201 package integrates precise thermal path design to maintain junction temperature within −55 °C to +150 °C during repeated ESD events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Clamping Voltage | 10 V at 8 kV contact discharge (30 ns), limiting stress on protected IC I/O pins |
| Stand-off Voltage | 5.5 V max - compatible with 5 V and 3.3 V logic rails without leakage-induced power loss |
| Line Capacitance | 4–5 pF at 1 MHz - preserves signal integrity on USB 2.0, I²C, and MIPI D-PHY interfaces |
| ESD Rating | ±30 kV air / ±14 kV contact per IEC 61000-4-2 Level 4 - meets smartphone and wearable certification requirements |
| Holding Voltage | 5.5–5.9 V - ensures automatic recovery post-transient without latch-up risk |
| Dynamic Resistance | 0.18 Ω - minimizes voltage overshoot during high-di/dt ESD pulses |
Pinout & Package
ESDZV5H-1BU2 is housed in the ST0201 package (0201 metric: 0.58 mm × 0.28 mm × 0.24 mm), a leadless, two-terminal surface-mount device compliant with ECOPACK2 environmental standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | Shared terminal for symmetrical ESD current conduction - no polarity assignment required |
| Pin 2 | Anode/Cathode (bidirectional) | Second terminal completing the bidirectional snapback path - interchangeable with Pin 1 in layout |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low clamping voltage | 10 V at 8 kV contact discharge ensures downstream IC I/O stays below absolute maximum ratings |
| Bidirectional symmetry | Identical VCL, VTrig, and VH for ± transients - eliminates need for polarity-aware routing |
| Sub-5 pF capacitance | 4 pF typical at 0 V bias enables use on 480 Mbps USB 2.0 and 1 Gbps MIPI data lines |
| High holding voltage margin | 5.9 V max VH > 5.5 V VRM prevents false triggering on 5 V supply rails |
Applications
| Smartphone Front-Facing Camera Interface | USB 2.0 OTG Port Protection |
|---|---|
Use Scenario: Protecting MIPI CSI-2 differential pairs between image sensor and AP against pocket discharge and cable hot-plug ESD. IC Role / Device Role / Timing Role: Bidirectional low-capacitance shunt clamp placed directly at connector side of data lanes. Use Value: 4 pF capacitance avoids signal rise-time degradation; 10 V clamping prevents sensor PHY latch-up during ±8 kV contact events. | Use Scenario: Safeguarding USB D+/D− lines in dual-role OTG ports exposed to frequent cable insertion/removal. IC Role / Device Role / Timing Role: Single-line TVS per data line, leveraging symmetry to handle both host and peripheral mode transients. Use Value: 5.5 V stand-off avoids DC leakage on 3.3 V data lines; ±14 kV contact rating exceeds USB-IF ESD test requirements. |
| Wireless Earbud Charging Case UART | Fitness Tracker Touch Controller I/O |
Use Scenario: Shielding UART TX/RX lines linking earbud case MCU to charging IC from ESD during user handling and lid actuation. IC Role / Device Role / Timing Role: Standalone bidirectional clamp on each UART line, placed adjacent to connector pads. Use Value: 0201 footprint saves <0.15 mm² per line - critical in ultra-thin case PCB real estate; 0.18 Ω RD limits clamping overshoot. | Use Scenario: Protecting capacitive touch controller GPIOs from finger-tip ESD in wrist-worn devices with minimal mechanical shielding. IC Role / Device Role / Timing Role: Low-leakage (≤50 nA @ 5.5 V) shunt protector mounted directly at touch pad traces. Use Value: 10 nA typical leakage at 25 °C prevents baseline drift in analog front-end; ±30 kV air rating covers direct skin contact events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional low-capacitance ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD1E05U06DPYR | 6 V stand-off, 7.5 V clamping (8 kV), 0.6 pF capacitance - lower C but tighter VRM | Better suited for 1.8 V/2.5 V I/O; insufficient margin for 5 V rails | Select when protecting sub-3 V interfaces where ultra-low C dominates over rail compatibility |
| ESD9B5.0ST5G | 5.0 V stand-off, 12 V clamping (8 kV), 12 pF capacitance - higher C and VCL | Acceptable for low-speed GPIO but degrades USB 2.0 eye diagram | Choose only for cost-sensitive 5 V systems where speed is not critical and board space allows larger SOD-523 |
Compared with TPD1E05U06DPYR and ESD9B5.0ST5G, ESDZV5H-1BU2 uniquely balances 5.5 V rail compatibility, 10 V clamping, and 4 pF capacitance in 0201 - making it optimal for mixed-voltage portable designs requiring universal I/O protection without sacrificing signal fidelity.

FAQ
What is the maximum operating temperature for ESDZV5H-1BU2?
The ESDZV5H-1BU2 supports an operating junction temperature range of −55 °C to +150 °C, validated per absolute maximum ratings in DS12237 Rev 5. This allows reliable operation in thermally demanding environments such as sealed wearable enclosures or near battery management ICs without derating.
Does ESDZV5H-1BU2 require orientation during PCB placement?
No - ESDZV5H-1BU2 is fully bidirectional and symmetric; its ST0201 package has no functional pin 1 designation. Marking rotation (up to 180°) is permitted for assembly differentiation, and either terminal may connect to either side of the protected line without performance impact.
How does the 0.18 Ω dynamic resistance affect system-level ESD performance?
The 0.18 Ω dynamic resistance directly reduces voltage overshoot during fast-rising ESD events (e.g., 30 ns rise time), lowering clamped voltage seen by downstream ICs. Measured TLP curves confirm stable snapback behavior up to 4 A, ensuring predictable clamping without secondary breakdown.
Can ESDZV5H-1BU2 be used on 1.8 V I/O lines?
Not recommended - its 5.5 V stand-off voltage exceeds typical 1.8 V rail tolerances, risking excessive leakage current and potential false triggering. For 1.8 V interfaces, ST's TPD1E05U06DPYR (6 V VRM) or similar lower-VRM devices are better matched.
