Product details
Overview
ESDZV5HS-1BF4 from STMicroelectronics is a bidirectional single-line TVS diode for I/O port ESD protection, featuring 4.5 pF line capacitance, 10 V clamping voltage (IEC 61000-4-2, 8 kV contact), 7 V holding voltage, 0.18 Ω dynamic resistance, and 0201 WLCSP package-designed for space-constrained mobile data lines.
For engineers reviewing the ESDZV5HS-1BF4 datasheet, ESDZV5HS-1BF4 pinout, ESDZV5HS-1BF4 application, or ESDZV5HS-1BF4 equivalent, this device addresses high-frequency signal integrity, ultra-low capacitance requirements, DC line hold-off stability, and IEC 61000-4-2 Level 4 compliance in miniaturized consumer electronics interfaces.
Technical Context
This snapback-type TVS uses symmetrical bidirectional structure to clamp both positive and negative ESD transients without polarity dependence. Its ultra-low 4.5 pF capacitance minimizes signal distortion on high-speed lines such as USB 2.0, MIPI D-PHY, and I²C.
The device triggers at 10–13.5 V and clamps to ≤10 V within 30 ns under 8 kV IEC contact discharge, with 7 V DC holding voltage ensuring no latch-up on 5 V rails. Dynamic resistance of 0.18 Ω sustains low-voltage drop during transient conduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Clamping Voltage | 10 V @ 8 kV IEC 61000-4-2 contact discharge (30 ns); ensures safe voltage seen by protected IC input |
| Line Capacitance | 4.5 pF @ 1 MHz; preserves signal integrity on >100 Mbps digital interfaces |
| Holding Voltage | 7 V min; prevents false triggering and maintains DC bias stability on 5 V systems |
| Dynamic Resistance | 0.18 Ω; limits voltage overshoot during high-current ESD pulse |
| ESD Rating | ±15 kV air / ±10 kV contact (IEC 61000-4-2 Level 4); meets smartphone front-panel ESD immunity |
| Package | 0201 WLCSP (0.30 × 0.30 mm); enables placement directly adjacent to connector pins |
| Leakage Current | 100 nA @ 5.5 V; avoids loading low-power sensor or touch I/O circuits |
Pinout & Package
ESDZV5HS-1BF4 is housed in a 2-terminal 0201 WLCSP package with top-side marking "U" indicating Pin 1. The package has no internal die pad; both terminals are solderable bumps aligned along one axis.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | Shared terminal for symmetrical ESD current path; connects to protected I/O line |
| Pin 2 | Anode/Cathode (bidirectional) | Shared terminal referenced to GND or common return; completes clamping loop |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low clamping voltage | 10 V at 8 kV contact discharge ensures downstream ICs see sub-logic-threshold overvoltage |
| Bidirectional symmetry | Identical VCL for +8 kV and –8 kV pulses eliminates polarity-aware layout constraints |
| Sub-5 pF capacitance | 4.5 pF enables use on 480 Mbps USB 2.0 and 1.5 Gbps MIPI D-PHY without equalization |
| High holding voltage | 7 V DC hold-off supports robust operation on 5 V supply rails without leakage-induced reset |
| 0201 WLCSP footprint | 0.30 × 0.30 mm body allows placement within 0.2 mm of connector pads for shortest possible protection path |
Applications
| Smartphone Front-Panel Touch Interface | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: ESD events from finger contact on glass-covered capacitive touch sensors near display bezel. IC Role / Device Role / Timing Role: TVS diode placed between touch controller I²C lines and flex connector, clamping transients before they reach GPIO inputs. Use Value: 4.5 pF capacitance avoids degrading 400 kHz I²C rise time; 10 V clamping prevents touch IC latch-up during ±15 kV air discharge. | Use Scenario: Electrostatic discharge induced on micro-USB or USB-C receptacle during cable insertion/removal. IC Role / Device Role / Timing Role: Single-line TVS on D+ or D− line, located immediately after connector pad to minimize inductance. Use Value: 0.18 Ω dynamic resistance limits clamping overshoot to <10.5 V; 0201 size fits tight routing near Type-B receptacle. |
| Wearable Heart-Rate Sensor Interface | Tablet MIPI D-PHY Clock Lane |
Use Scenario: Repeated ESD exposure on wristband strap contacts or button actuation in dry environments. IC Role / Device Role / Timing Role: Protection on analog front-end ADC input or low-power I²C sensor bus operating at 1.8 V. Use Value: 100 nA leakage avoids offset error in µA-range biosignal paths; 7 V holding voltage exceeds 1.8 V rail margin safely. | Use Scenario: ESD coupling into high-speed MIPI clock lane (250 MHz+) from nearby antenna or button traces. IC Role / Device Role / Timing Role: Bidirectional TVS on CLK+ line, placed before serializer/deserializer input to preserve jitter budget. Use Value: 4.5 pF capacitance adds <0.1 UI timing uncertainty at 2.5 Gbps; symmetric clamping avoids duty-cycle distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar single-line bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD1E05U06DPYR | 5.5 pF capacitance, 11.5 V clamping (8 kV), 6.5 V holding voltage | Slightly higher capacitance limits use on >300 Mbps interfaces; lower hold-off may risk 5 V rail instability | Preferred where JEDEC-compliant 0201 footprint and TI's production consistency are prioritized over minimal capacitance |
| UMK105CG4R7CB-F | 4.7 pF, 10.5 V clamping, 6.8 V holding, 0201 multilayer ceramic varistor (MLCV) | Higher leakage (~500 nA), non-snapback behavior yields slower turn-on; less precise clamping threshold | Selected when cost sensitivity outweighs need for sub-100 nA leakage and sharp snapback response |
Compared with TPD1E05U06DPYR and UMK105CG4R7CB-F, ESDZV5HS-1BF4 delivers the lowest capacitance and tightest clamping control among 0201 single-line protectors-critical for preserving eye diagrams on gigabit-rate mobile interfaces while maintaining DC rail stability.

FAQ
What is the maximum peak pulse current rating for ESDZV5HS-1BF4?
The device is rated for 4 A peak pulse current under 8/20 μs waveform per IEC 61000-4-5 surge testing. This reflects its ability to safely divert transient energy without degradation when used within specified layout and thermal conditions-verified across 1,000+ ESD strikes in qualification testing.
Can ESDZV5HS-1BF4 be used on a 3.3 V I/O line?
Yes. With a 7 V minimum holding voltage and 10 V clamping, it provides ample margin above 3.3 V rails. Its 100 nA leakage at 5.5 V ensures negligible loading on 3.3 V logic, and the bidirectional structure protects against both positive and negative transients without external biasing.
Is the 0201 WLCSP package compatible with standard SMT reflow profiles?
Yes. ST specifies compatibility with IPC/JEDEC J-STD-020 Class 3 reflow profiles, including peak temperatures up to 245 °C for ≤30 seconds. The recommended profile includes controlled ramp rates (≤3 °C/s) and a 60-second dwell above 217 °C to ensure reliable solder joint formation without bump damage.
How does ESDZV5HS-1BF4 differ from standard Zener-based TVS diodes?
It uses a snapback silicon-controlled structure-not a Zener junction-enabling lower dynamic resistance (0.18 Ω vs typical 1–5 Ω), faster turn-on (<1 ns), and tighter clamping uniformity. This results in lower let-through voltage during ESD events and reduced stress on protected ICs compared to conventional Zener TVS devices.
