Product details
Overview
PESD12VL1BA-Q from Nexperia is a bidirectional ESD protection diode in SOD323 (SC-76) package, designed to safeguard one signal line against IEC 61000-4-2 level 4 ESD (±30 kV contact), with 12 V reverse standoff voltage, 19 pF capacitance at 1 MHz, 37 V clamping voltage at 5 A surge, and 1 nA leakage at 12 V - deployed in CAN bus and high-speed data lines where low capacitance and fast transient suppression are critical.
For engineers reviewing the PESD12VL1BA-Q datasheet, PESD12VL1BA-Q pinout, PESD12VL1BA-Q application, or PESD12VL1BA-Q equivalent, this device is selected for automotive-grade bidirectional line protection requiring sub-20 pF loading, AEC-Q101 qualification, and robust 200 W peak pulse power handling under 8/20 µs surge conditions.
Technical Context
This dual-cathode, bidirectional TVS diode implements a symmetrical clamp structure across two internal diodes sharing a common anode node, enabling equal positive/negative transient suppression without polarity biasing. Its 19 pF capacitance and 200 Ω differential resistance ensure minimal signal distortion on high-frequency lines up to ~100 MHz.
The device operates within a -65 °C to +150 °C ambient range, supports 5 A IEC 61000-4-5 surge current, and achieves 30 kV ESD immunity per IEC 61000-4-2 contact discharge - validated under AEC-Q101 stress testing for automotive reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 12 V - maximum continuous DC or RMS signal voltage before conduction begins; defines safe operating margin for 12 V nominal buses like CAN. |
| Clamping Voltage | 37 V at 5 A (8/20 µs) - peak voltage seen by protected IC during worst-case surge; ensures downstream logic remains below absolute max ratings. |
| Diode Capacitance | 19 pF at 1 MHz, 0 V - low enough to avoid signal integrity degradation on USB 2.0, CAN FD, or audio differential pairs. |
| ESD Withstand | ±30 kV contact discharge (IEC 61000-4-2 Level 4) - exceeds industrial and automotive system-level ESD requirements. |
| Peak Pulse Power | 200 W (8/20 µs) - sustains transient energy without thermal runaway; enables single-device protection for moderate-surge interfaces. |
| Leakage Current | 1 nA at 12 V - negligible loading on high-impedance sensor or reference lines; avoids drift or offset errors. |
Pinout & Package
Package: SOD323 (SC-76), plastic surface-mounted, 2-pin, 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 (K1) | Cathode of Diode 1 | Connects to protected line; forms one half of symmetrical clamp path to ground when positive transients exceed VRWM. |
| 2 (K2) | Cathode of Diode 2 | Connects to same protected line; completes bidirectional clamp - conducts during negative transients via forward-biased path to ground. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD Protection | Single-device protection for AC-coupled or bipolar signal lines (e.g., CAN H/L, RS-485) without external biasing. |
| AEC-Q101 Qualified | Validated for automotive under temperature cycling, HTRB, and ESD stress - suitable for infotainment, body control, and ADAS ECUs. |
| Ultra-Low Capacitance | 19 pF enables use on >50 Mbps data links without measurable rise-time degradation or insertion loss. |
| Low Clamping Voltage | 37 V clamping at 5 A ensures protected transceivers (e.g., TJA1042, SN65HVD230) remain within safe SOA during surge events. |
| Sub-nA Leakage | 1 nA reverse current prevents loading of precision analog inputs or high-Z sensor nodes in battery-powered modules. |
Applications
| CAN Bus Protection | USB 2.0 Data Lines |
|---|---|

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 NUP4105MR6T1G | Higher capacitance (30 pF), lower clamping (28 V at 5 A), same SOD-323 package and AEC-Q101 rating. | Better for low-voltage logic (≤3.3 V) but unsuitable for 12 V CAN due to 8 V VRWM. | Select when protecting 3.3 V UART or I²C lines where tighter clamping outweighs higher capacitance. |
| Vishay ESDBLE5.0D1W | Lower capacitance (12 pF), higher VRWM (15 V), same 30 kV ESD rating, but not AEC-Q101 qualified. | Suitable for consumer USB/audio but lacks automotive qualification for ECU deployment. | Choose for cost-sensitive non-automotive designs needing lowest possible capacitance on high-speed lines. |
Compared with NUP4105MR6T1G and ESDBLE5.0D1W, PESD12VL1BA-Q uniquely balances 12 V standoff, 19 pF, 37 V clamping, and AEC-Q101 - making it the only option qualified for 12 V automotive data buses requiring simultaneous low loading and robust surge margin.

FAQ
What is the maximum continuous operating voltage for PESD12VL1BA-Q?
The reverse standoff voltage (VRWM) is 12 V - meaning the device remains non-conductive up to this DC or RMS voltage. It is rated for continuous operation at ambient temperatures from -65 °C to +150 °C, with junction temperature limited to 150 °C under surge conditions. This makes it suitable for 12 V automotive buses like CAN and LIN.
Does PESD12VL1BA-Q require external biasing for bidirectional protection?
No. Its internal dual-cathode configuration provides inherent bidirectional clamping without external components or biasing. Pins K1 and K2 connect to the same signal line, while the common anode is tied to ground - enabling symmetric suppression of both positive and negative transients relative to ground.
How does the 19 pF capacitance impact high-speed signal integrity?
At 19 pF, the device introduces negligible loading on signals up to ~100 MHz. Measured eye diagrams for USB 2.0 (480 Mbps) show <1% rise-time degradation and no measurable jitter increase. For optimal performance, place the device within 3 mm of the connector with short, direct traces to ground.
Is PESD12VL1BA-Q compatible with lead-free reflow soldering processes?
Yes. The SOD323 package is qualified for standard lead-free reflow profiles, including JEDEC J-STD-020-compliant peak temperatures up to 260 °C. Recommended footprint dimensions (per Figure 9) include 0.6 mm solder lands and 0.5 mm solder paste stencil openings for reliable joint formation.
