Product details
Overview
ESDZV5-1BV2 from STMicroelectronics is a bidirectional single-line TVS diode designed for ESD protection of high-speed data lines and I/O ports in space-constrained portable electronics. It delivers 15 kV contact / 25 kV air discharge ESD immunity per IEC 61000-4-2, ultra-low 7 V clamping voltage at 8 kV contact discharge, 5 pF typical line capacitance, and operates from –40 °C to +150 °C junction temperature.
For engineers reviewing the ESDZV5-1BV2 datasheet, ESDZV5-1BV2 pinout, ESDZV5-1BV2 application, or ESDZV5-1BV2 equivalent, key selection criteria include clamping voltage under 8 kV ESD stress, sub-6 pF capacitance for USB/MIPI signal integrity, 01005 footprint compatibility, and VH (holding voltage) margin relative to system DC bias.
Technical Context
This device employs a snapback-triggered silicon avalanche structure optimized for ultra-low clamping. Its bidirectional architecture enables symmetric transient suppression on AC-coupled or dual-rail interfaces without polarity constraints, while the 0.18 Ω dynamic resistance ensures minimal voltage overshoot during 5 A surge events per IEC 61000-4-5.
The 5.5 V stand-off voltage (VRM) and 4.0–4.8 V holding voltage (VH) define its DC blocking window: systems with DC bias below 4.0 V guarantee reliable turn-off after transient clearance, preventing latch-up or leakage-induced signal degradation in always-on sensor or audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | 15 kV contact / 25 kV air discharge - meets industrial-grade ESD immunity requirements for handheld consumer devices |
| Clamping Voltage (VCL) | 7 V @ 8 kV contact discharge, 30 ns - limits voltage seen by protected IC to safe level during fast ESD event |
| Line Capacitance (Cline) | 5–6 pF @ 1 MHz, 30 mV - preserves signal integrity on USB 2.0, MIPI D-PHY, and I²C buses |
| Stand-off Voltage (VRM) | 5.5 V min - blocks normal operating voltages up to 5.5 V while remaining non-conductive |
| Holding Voltage (VH) | 4.0–4.8 V - ensures automatic recovery to high-impedance state after transient if DC bias < 4.0 V |
| Dynamic Resistance (RD) | 0.18 Ω - minimizes IR drop during 5 A surge, reducing clamping overshoot |
| Leakage Current (IRM) | 100 nA @ VRM = 5.5 V - avoids loading low-power sensor or battery-backed circuits |
Pinout & Package
ESDZV5-1BV2 uses the ST01005 package: 0.15 mm × 0.465 mm × 0.255 mm (L × W × H), 2-terminal surface-mount device with no internal die pad. The package is lead-free, halogen-free, and ECOPACK2-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Transient current entry point for negative transients | Connects to protected line; forms bidirectional conduction path with cathode during ±ESD events |
| Cathode (Pin 2) | Transient current entry point for positive transients | Connects to protected line; completes symmetrical snapback path with anode for full bidirectional clamping |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low clamping voltage | 7 V at 8 kV contact discharge - reduces risk of gate oxide damage in 1.8 V/3.3 V interface ICs |
| Bidirectional snapback structure | Symmetric VTRIG (5.8–8.5 V) and VH (4.0–4.8 V) - eliminates need for polarity-aware layout on differential or AC-coupled lines |
| 01005 footprint | 0.15 mm × 0.465 mm body - saves >60% board area vs. 0201 ESD diodes, enabling denser RF module layouts |
| Low line capacitance | 5–6 pF - maintains >90% signal amplitude at 500 MHz, critical for MIPI D-PHY v2.1 eye diagram compliance |
| ECOPACK2 compliance | Halogen-free, RoHS-compliant materials - satisfies EU REACH and China RoHS environmental mandates for global consumer shipments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD1E05U06DPYR | 6.5 pF capacitance, 12 kV contact ESD rating, 10 V clamping at 8 kV | Higher clamping increases risk of 1.8 V I/O damage; suitable only where 12 kV suffices | Select when lower cost outweighs need for 15 kV rating and tighter clamping |
| ESD9X5.0ST5G | 12 pF capacitance, 12 kV contact rating, 14 V clamping at 8 kV | Excessive capacitance degrades USB 2.0 signal integrity; clamping too high for low-voltage I/O | Avoid for high-speed or sub-3.3 V interfaces; consider only for legacy 5 V UART lines |
Compared with TPD1E05U06DPYR and ESD9X5.0ST5G, ESDZV5-1BV2 provides superior ESD robustness (15 kV), lower clamping (7 V), and half the line capacitance-making it uniquely suited for next-gen wearable and smartphone sensor interfaces where signal fidelity and miniaturization are critical.

FAQ
What is the maximum DC voltage that can be safely applied across ESDZV5-1BV2 without triggering conduction?
The device remains non-conductive up to its 5.5 V minimum stand-off voltage (VRM). However, for guaranteed turn-off after ESD events, the applied DC bias must stay below the minimum holding voltage of 4.0 V. Exceeding 4.0 V risks incomplete recovery and sustained leakage, especially at elevated temperatures.
Can ESDZV5-1BV2 be used to protect USB 3.0 SuperSpeed lanes?
No. With 5–6 pF capacitance, ESDZV5-1BV2 is optimized for USB 2.0 (480 Mbps), MIPI D-PHY, and I²C. USB 3.0 SuperSpeed (5 Gbps) requires sub-0.5 pF capacitance to avoid signal integrity loss; this device would cause excessive insertion loss and jitter beyond specification limits.
How does the 01005 package impact reflow soldering yield?
The 0.15 mm × 0.465 mm ST01005 footprint demands precise stencil design (75 µm thickness, 100% aperture ratio) and placement force ≤1.0 N. Excessive force causes solder paste extrusion and bridging; insufficient force leads to open joints. ST recommends bottom-side optical alignment and rigid PCB support during reflow to prevent tombstoning.
Is ESDZV5-1BV2 suitable for protecting analog microphone bias lines?
Yes, provided the DC bias is ≤4.0 V. Its 100 nA leakage at 5.5 V ensures negligible impact on electret microphone output level or SNR. The 5 pF capacitance also avoids high-frequency roll-off in 20 kHz audio paths. For MEMS microphones with 1.8 V bias, it provides optimal clamping without affecting sensitivity calibration.
