Product details
Overview
ESDALC14V2-2BP5 from STMicroelectronics is a bidirectional low-capacitance ESD protection array for two signal lines, featuring 14.2 V minimum breakdown voltage, 14 pF capacitance at 3 V, <1 µA leakage current, and 50 W peak pulse power (8/20 µs), deployed in high-density interfaces like xDSL modems and video equipment.
For engineers reviewing the ESDALC14V2-2BP5 datasheet, ESDALC14V2-2BP5 pinout, ESDALC14V2-2BP5 application, or ESDALC14V2-2BP5 equivalent, key selection criteria include clamping voltage (12 V max), dynamic resistance (1.5 Ω typ), IEC61000-4-2 Level 4 compliance (15 kV air / 8 kV contact), and SOT665 footprint constraints.
Technical Context
This monolithic dual-channel Transil™ array uses avalanche diode structures to clamp transient overvoltages before sensitive IC inputs are damaged. It operates bidirectionally with symmetrical breakdown (VBR = 14.2 V min) and delivers fast response (<1 ns) to ESD events per IEC61000-4-2.
The device integrates two independent protection paths in a single SOT665 package, optimized for high-frequency signal integrity via ultra-low junction capacitance (14 pF @ 3 V) and low dynamic resistance (1.5 Ω typ), enabling use on USB 2.0, HDMI, and LVDS lines without signal degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 14.2 V min - ensures reliable triggering above normal signal swing while avoiding false trips |
| Clamping Voltage (VCL) | 12 V max @ IPP - limits voltage seen by protected IC during 8/20 µs surge |
| Junction Capacitance | 14 pF @ 3 V - preserves signal integrity on high-speed data lines up to ~300 MHz |
| Leakage Current (IRM) | <1 µA @ VRM - prevents DC loading of bias-sensitive analog or reference circuits |
| Peak Pulse Power | 50 W (8/20 µs) - withstands repeated ESD strikes without degradation |
| Dynamic Resistance (Rd) | 1.5 Ω typ - minimizes voltage overshoot during fast transients |
| ESD Rating | IEC61000-4-2 Level 4: 15 kV air / 8 kV contact - meets industrial and telecom immunity requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESDALC25-2BP5 | Higher breakdown (25 V min) and lower capacitance (8 pF @ 3 V); same SOT665 package and pinout | Better suited for 24 V industrial I/O or higher-voltage analog sensor lines | Select when system operating voltage exceeds 12 V or lower capacitance is critical |
| TPD2E001DRYR | Single-channel, 12 pF @ 0 V, 10 V clamping, 0.5 µA leakage; X2SON-6 package (1.0 × 1.0 mm) | Requires two devices for dual-line protection; smaller footprint but no common-cathode configuration | Choose for ultra-compact layouts where dual-channel integration is not required |
Compared with ESDALC25-2BP5, this part offers tighter clamping for 3.3 V systems but less margin for 5 V rails; versus TPD2E001DRYR, it provides integrated dual-channel symmetry and lower dynamic resistance at the cost of slightly larger area.

FAQ
What is the maximum operating temperature for ESDALC14V2-2BP5?
The device supports continuous operation from −40°C to +150°C ambient temperature, with a maximum junction temperature of 150°C. Its thermal performance is validated for reflow soldering up to 260°C for 10 seconds, and its ECOPACK® lead-free construction ensures compatibility with modern assembly processes.
Does ESDALC14V2-2BP5 require external biasing or control signals?
No. This is a passive bidirectional TVS array with no external control pins or bias requirements. It operates solely based on voltage threshold behavior: conducting only when reverse voltage exceeds 14.2 V (min), with leakage remaining below 1 µA at normal operating voltages.
Can ESDALC14V2-2BP5 protect AC-coupled high-speed lines?
Yes. Its symmetrical bidirectional structure and 14 pF capacitance at 3 V make it suitable for AC-coupled differential interfaces such as USB 2.0 and HDMI. The low dynamic resistance (1.5 Ω typ) ensures effective clamping without distorting signal swing or common-mode rejection.
Is the exposed pad (Pin 4) electrically connected internally?
Yes. The exposed pad is internally connected to the cathode node (Pin 2) and serves as both a thermal dissipation path and an EMI ground return. It must be soldered to a PCB ground plane using at least four thermal vias to maintain thermal stability and optimal clamping performance during ESD events.
