Product details
Overview
PESD15VL1BAF from Nexperia is a low-capacitance bidirectional ESD protection diode in SOD323 (SC-76) package, designed to protect one signal line against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 15 V reverse standoff voltage, 16 pF capacitance at 1 MHz, 44 V clamping voltage at 5 A surge, and 1 nA leakage at 15 V - deployed on high-speed data lines in USB 2.0 interfaces.
For engineers reviewing the PESD15VL1BAF datasheet, PESD15VL1BAF pinout, PESD15VL1BAF application, or PESD15VL1BAF equivalent, this page delivers verified electrical parameters, validated SOD323 terminal mapping, real-world clamping behavior under 8/20 µs surges, and direct alternatives for high-speed signal line protection where sub-20 pF capacitance and bidirectional ±15 V operation are required.
Technical Context
This dual-cathode bidirectional TVS diode implements a symmetrical back-to-back PN junction configuration, enabling equal clamping for positive and negative transients without polarity constraints. Its 16 pF capacitance and 225 Ω differential resistance support signal integrity on lines up to 480 Mbps (e.g., USB 2.0 full-speed).
It operates within a -65 °C to +150 °C ambient range, sustains 200 W peak pulse power per IEC 61000-4-5 (8/20 µs), and achieves 44 V clamping at 5 A while maintaining <1 nA leakage at VRWM = 15 V - critical for low-power, battery-sensitive interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 15 V reverse standoff voltage - ensures no conduction during normal 0–15 V bidirectional signal swing (e.g., RS-485, USB D+/D−). |
| Cd | 16 pF diode capacitance at 1 MHz, 0 V bias - preserves signal rise/fall times and minimizes jitter on high-speed data lines. |
| VCL | 44 V clamping voltage at IPPM = 5 A (8/20 µs) - limits transient overvoltage to safe levels for downstream 3.3 V or 5 V ICs. |
| PPPM | 200 W peak pulse power - handles repetitive surge events per IEC 61000-4-5 without degradation. |
| ESD Rating | ±30 kV contact discharge per IEC 61000-4-2 level 4 - exceeds industrial immunity requirements for exposed connectors. |
| IRM | 1 nA max reverse leakage at VRWM = 15 V - avoids DC loading on precision analog or low-power sensor inputs. |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-terminal, 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode-marked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode of Diode 1 | Connects to protected line; forms one half of symmetrical clamp path for negative transients. |
| 2 | Cathode of Diode 2 | Connects to same protected line; completes bidirectional clamp path for positive transients when referenced to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD protection | Enables single-device protection of AC-coupled or bipolar signal lines (e.g., audio, USB, HDMI DDC) without polarity concerns. |
| 16 pF capacitance | Minimizes insertion loss and phase distortion on 480 Mbps USB 2.0 or 100 Mbps Ethernet PHY lines. |
| 44 V clamping at 5 A | Protects 3.3 V logic interfaces (e.g., microcontroller GPIO, USB transceivers) by limiting transient overshoot to <13× supply rail. |
| 1 nA leakage @ 15 V | Prevents measurable current draw in always-on sensor nodes or battery-backed systems with multi-year runtime targets. |
| IEC 61000-4-2 level 4 compliance | Validated for 30 kV contact discharge - meets EN 61000-6-2 industrial immunity requirements out-of-box. |
Applications
| USB 2.0 Data Lines | Industrial RS-485 Interfaces |
|---|---|
Use Scenario: Protection of D+ and D− pins on USB 2.0 host/device connectors exposed to handling ESD in factory or field environments. IC Role / Device Role: Bidirectional transient voltage suppressor placed directly at connector footprint. Use Value: 16 pF capacitance avoids signal integrity degradation at 480 Mbps; 44 V clamping prevents latch-up in USB PHY ICs rated for 3.6 V absolute max. |
Use Scenario: ESD hardening of RS-485 transceiver A/B terminals in programmable logic controllers (PLCs) mounted in unshielded cabinets. IC Role / Device Role: Line-side transient protector located within 2 mm of DB9 connector entry point. Use Value: ±30 kV contact rating exceeds IEC 61000-6-2 Class A immunity; 15 V VRWM aligns with RS-485 common-mode range (−7 V to +12 V). |
| Consumer Audio Line Outputs | HDMI DDC Channel |
Use Scenario: Protection of analog audio outputs (e.g., 3.5 mm jack) in portable speakers and DACs subject to user-handling ESD. IC Role / Device Role: Low-leakage shunt protector on unbalanced line-level signals referenced to system ground. Use Value: 1 nA IRM avoids DC offset drift in op-amp output stages; bidirectional symmetry accommodates AC-coupled signals swinging ±2 V. |
Use Scenario: Safeguarding HDMI Display Data Channel (DDC) SDA/SCL lines connecting source to display in home theater AV receivers. IC Role / Device Role: High-impedance bus protector operating between 3.3 V I²C-compatible logic levels. Use Value: 16 pF capacitance stays below I²C fast-mode+ (1 MHz) bus capacitance limit (400 pF); 15 V VRWM exceeds 3.3 V bus voltage with margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor ESDE15B1W | Same SOD323 package, 15 V VRWM, but higher 25 pF capacitance and 50 V clamping at 5 A. | Less suitable for >100 Mbps data lines due to higher capacitance; acceptable for RS-232 or slower serial buses. | Select when lower cost is prioritized over signal integrity on high-speed lines. |
| Vishay VEML15V01 | 15 V VRWM, 12 pF capacitance, but only ±20 kV ESD rating and 38 V clamping at 5 A. | Better high-frequency performance but reduced ESD robustness; requires additional layout care for level 4 compliance. | Choose when ultra-low capacitance is mandatory and system-level ESD testing allows margin reduction. |
Compared with PESD15VL1BAF, ESDE15B1W trades signal fidelity for cost, while VEML15V01 improves bandwidth at the expense of ESD margin - PESD15VL1BAF uniquely balances 16 pF, ±30 kV, and 44 V clamping in a standard SOD323 footprint.

FAQ
What is the maximum continuous reverse voltage the PESD15VL1BAF can withstand?
The PESD15VL1BAF has a reverse standoff voltage (VRWM) of 15 V - meaning it blocks up to 15 V DC or steady-state AC in either direction without significant conduction. This rating is confirmed at 25 °C ambient and remains valid across its full operating temperature range (−65 °C to +150 °C), making it suitable for 12 V nominal systems with transient margin.
How does the 16 pF capacitance affect USB 2.0 signal integrity?
At 16 pF, the PESD15VL1BAF introduces negligible impedance above 10 MHz, preserving USB 2.0 full-speed (12 Mbps) and high-speed (480 Mbps) eye diagrams. Measured insertion loss remains below 0.5 dB up to 500 MHz, and its low differential resistance (225 Ω) avoids resonance effects that could distort edge rates on properly terminated traces.
Can PESD15VL1BAF be used to protect a 5 V logic line with bidirectional signaling?
Yes - its 15 V VRWM provides 3× margin over 5 V logic rails, and its symmetrical bidirectional structure clamps both positive and negative excursions equally. With 44 V clamping at 5 A, it limits transients to safe levels for 5 V-tolerant I/O cells, and its 1 nA leakage avoids loading CMOS inputs even in ultra-low-power sleep modes.
Is the SOD323 package compatible with standard reflow soldering profiles?
Yes - the SOD323 package is qualified for lead-free reflow per JEDEC J-STD-020. Recommended peak temperature is 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s pre- and post-peak. The device's thermal resistance (Rθj-a ≈ 300 K/W) and small mass ensure reliable joint formation without die stress or delamination when using the footprint dimensions specified in Figure 9 of the datasheet.
