Product details
Overview
ESDAVLC5-1BF4 from STMicroelectronics is a bidirectional single-line TVS diode for ESD protection of high-speed data lines, featuring 7 pF line capacitance, ±12 kV contact/±30 kV air IEC 61000-4-2 compliance, and 11.7 V clamping voltage at 1.7 A (8/20 µs), deployed in smartphones and portable multimedia interfaces.
For engineers reviewing the ESDAVLC5-1BF4 datasheet, ESDAVLC5-1BF4 pinout, ESDAVLC5-1BF4 application, or ESDAVLC5-1BF4 equivalent, key selection criteria include ultra-low capacitance for signal integrity, 0201 footprint constraints, clamping performance under IEC-level-4 transients, and leakage current stability across temperature.
Technical Context
This device operates as a voltage-clamped transient suppressor with symmetrical bidirectional conduction, enabling protection of AC-coupled or differential I/O without polarity sensitivity. Its low dynamic resistance (0.67 Ω) ensures rapid energy shunting during sub-100 ns ESD events while maintaining minimal signal distortion.
Designed for integration into space-constrained RF and high-speed digital paths, it delivers 1.5 GHz cutoff frequency and stable 7 pF capacitance at 0 V bias-critical for USB 2.0, HDMI, and MIPI D-PHY interface protection where insertion loss and timing skew must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Clamping Voltage (IEC 61000-4-2) | 16.3 V at 30 ns - limits peak stress on protected IC I/O during real-world ESD contact discharge |
| Line Capacitance | 7 pF at 1 MHz - preserves signal integrity on 480 Mbps USB 2.0 and 1.5 Gbps MIPI lanes |
| Working Voltage (VRM) | ±5.3 V - supports common logic rails including 3.3 V and 5 V I/O without leakage-induced offset |
| Leakage Current | 100 nA at ±5.3 V - avoids DC loading on precision analog or low-power sensor interfaces |
| Breakdown Voltage (VBR) | 5.8–8.5 V at 1 mA - ensures reliable triggering above normal operating swing but below IC absolute maximum ratings |
| Cut-off Frequency | 1.5 GHz - maintains passband integrity for high-frequency serial links up to ~750 MHz fundamental |
| Package Size | 0201 (0.6 × 0.3 mm) - enables placement directly adjacent to connector pins with <0.18 mm² PCB area |
Pinout & Package
ESDAVLC5-1BF4 is housed in a lead-free, RoHS-compliant 0201 surface-mount package (ST Microelectronics ECOPACK®2 grade). The device has two terminals: anode and cathode arranged symmetrically for bidirectional operation; no polarity marking is required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (symmetrical) | Bidirectional ESD current path - connects to protected line; no fixed polarity assignment |
| Terminal 2 | Anode/Cathode (symmetrical) | Return path to ground or reference plane - completes transient current loop during ESD event |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low line capacitance | 7 pF enables use on 480 Mbps USB 2.0 and MIPI D-PHY v1.2 interfaces without degrading eye diagram margin |
| IEC 61000-4-2 Level 4 exceedance | ±30 kV air / ±12 kV contact rating provides design margin beyond industrial ESD immunity requirements |
| 0201 footprint | 0.18 mm² board area reduces routing congestion near connectors and allows co-location with high-speed traces |
| Low clamping voltage | 11.7 V at 1.7 A (8/20 µs) limits voltage overshoot to stay within typical 12 V I/O absolute maximum ratings |
| Low leakage current | 100 nA at ±5.3 V prevents measurable DC error in precision analog front-ends or battery-monitoring circuits |

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, 12.5 V clamping at 1 A (IEC), 0201 package | Slightly lower capacitance but higher clamping; rated for 1 A IEC pulse vs. 1.7 A for ESDAVLC5-1BF4 | Prefer when lowest possible capacitance is critical and system-level ESD stress is ≤8 kV contact |
| UMK105CG7R0CV-F | 7 pF MLCC-based ESD filter (not TVS); no clamping action; relies on series impedance + shunt capacitance | No active voltage limiting - only filtering; requires external series resistor for full ESD suppression | Select only in cost-sensitive consumer designs where clamping is secondary to broadband noise filtering |
Compared with TPD1E05U06DPYR and UMK105CG7R0CV-F, ESDAVLC5-1BF4 offers superior IEC-level-4 robustness (±12 kV contact) and true voltage clamping without external components-making it optimal for compact, high-reliability portable interfaces demanding both low capacitance and guaranteed overvoltage limiting.

FAQ
What is the maximum recommended PCB trace length between ESDAVLC5-1BF4 and the protected I/O pin?
ST recommends placing the device within 3 mm of the protected I/O pin to minimize inductive voltage overshoot during ESD events. Longer traces increase L×di/dt spikes that can exceed the IC's absolute maximum rating even with proper clamping. Layout guidelines in AN4022 confirm that <2 mm trace length achieves <5% clamping voltage degradation versus ideal placement.
Does ESDAVLC5-1BF4 require a dedicated ground plane connection, and what is the preferred via strategy?
Yes - a low-inductance ground return is essential. ST specifies using at least two 0.2 mm diameter vias spaced ≤0.3 mm apart, connecting directly to an unbroken inner ground plane. This reduces ground loop inductance to <0.3 nH, ensuring clamping voltage remains within specification during 1.7 A transient currents.
Can ESDAVLC5-1BF4 be used on 5 V tolerant I/O lines without derating?
Yes - its ±5.3 V working voltage (VRM) and 5.8–8.5 V breakdown range fully accommodate 5 V logic rails. Measured leakage remains ≤100 nA at 5.3 V, and clamping voltage (11.7 V at 1.7 A) stays safely below standard 5 V I/O absolute maximum ratings of 12–13 V.
How does the 0.67 Ω dynamic resistance impact system-level ESD performance?
The 0.67 Ω dynamic resistance (measured at 100 ns pulse width) directly determines voltage overshoot during fast ESD transients: Vovershoot = Ipp × Rdyn + Vclamp. At 16 A TLP current, this contributes only ~10.7 V additional drop - confirming the 19.2 V total clamping value is dominated by intrinsic junction behavior, not parasitic resistance.
