Product details
Overview
D1V8L1BS2LP3 from Diodes Incorporated is a single-channel bidirectional transient voltage suppression (TVS) diode designed for ESD and surge protection of high-speed data lines in portable electronics. It features a 1.8V reverse working voltage, 2.1V minimum breakdown voltage, 25A peak pulse current (8/20µs), 32pF typical junction capacitance, and ±30kV IEC 61000-4-2 contact/air ESD rating - enabling robust protection in space-constrained USB, HDMI, or audio interfaces.
For engineers reviewing the D1V8L1BS2LP3 datasheet, D1V8L1BS2LP3 pinout, D1V8L1BS2LP3 application, or D1V8L1BS2LP3 equivalent, key selection criteria include clamping voltage at 1A (3.0V) and 25A (7.0V), ultra-low profile (0.30mm height), DFN0603-2 footprint compatibility, and compliance with IEC 61000-4-5 surge and IEC 61000-4-2 ESD standards.
Technical Context
This TVS operates in bidirectional mode across two terminals, providing symmetrical clamping for AC-coupled signal lines such as USB D+/D− or audio differential pairs. Its low 32pF capacitance ensures minimal signal integrity impact on data rates up to 480 Mbps (USB 2.0), while the 7.0V clamping voltage at 25A limits downstream IC stress during lightning-induced surges.
The device uses silicon avalanche technology with a planar junction structure optimized for fast response (<1 ns) to ESD transients. Thermal design relies on FR-4 PCB copper pad layout per Diodes' recommended footprint, delivering 500°C/W junction-to-ambient thermal resistance and supporting continuous power dissipation up to 250 mW at +25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 1.8 V - Maximum DC or RMS signal voltage the line can carry without triggering conduction |
| Breakdown Voltage (Min) | 2.1 V @ 1 mA - Ensures reliable turn-on before sensitive ICs exceed absolute maximum ratings |
| Clamping Voltage (1A) | 3.0 V @ 8/20µs - Limits transient overvoltage seen by protected IC during moderate surges |
| Clamping Voltage (25A) | 7.0 V @ 8/20µs - Maintains safe voltage ceiling under severe lightning-surge conditions |
| Junction Capacitance | 32 pF @ 0 V, 1 MHz - Low enough to avoid signal attenuation or timing skew on USB 2.0 or I²C lines |
| ESD Rating | ±30 kV contact & air (IEC 61000-4-2) - Meets highest industrial handheld ESD immunity requirement |
| Package | X3-DFN0603-2 - 0.61 mm × 0.30 mm footprint with 0.30 mm max height for ultra-thin mobile PCBs |
Pinout & Package
Package: X3-DFN0603-2 - 2-terminal, bottom-terminated, lead-free molded plastic package with matte tin finish on copper leadframe; moisture sensitivity level 1 (J-STD-020); UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (Bidirectional) | Common terminal for symmetrical ESD clamping - no polarity distinction; connects to protected signal line |
| Pin 2 | Anode/Cathode (Bidirectional) | Second terminal forming bidirectional path - ties to same signal net or ground-return path depending on layout |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.30 mm max height - enables use under mechanical shields and in <8 mm thick smartphones/tablets |
| IEC 61000-4-5 surge rating | 25 A peak pulse current (8/20 µs) - withstands induced surges from nearby lightning strikes |
| Low capacitance interface | 32 pF - preserves signal rise time and eye diagram integrity on 480 Mbps USB 2.0 channels |
| Green RoHS compliance | Halogen- and antimony-free, <900 ppm Br/Cl, <1000 ppm Sb - meets strict environmental requirements for global consumer shipments |
Applications
| USB 2.0 Data Lines | HDMI Hot-Plug Detection |
|---|---|
Use Scenario: Protecting D+ and D− lines in smartphone USB ports against repeated ESD events during cable insertion/removal. IC Role / Device Role / Timing Role: Bidirectional clamping TVS placed directly at connector, shunting transients before they reach USB transceiver PHY. Use Value: Prevents latch-up or gate oxide damage in USB PHY ICs while maintaining <1 ns response and 32 pF loading for full-speed signaling. | Use Scenario: Safeguarding HDMI HPD (Hot-Plug Detect) and CEC (Consumer Electronics Control) lines in tablets and docking stations. IC Role / Device Role / Timing Role: Low-capacitance TVS on 5V-tolerant control lines to suppress contact ESD without false HPD toggling. Use Value: Eliminates system reset or display dropouts caused by ±30 kV ESD on HPD pins, with no added RC delay due to 32 pF capacitance. |
| Smartphone Audio Jack | Industrial Sensor Interface |
Use Scenario: ESD protection for analog audio paths (MIC, EAR, GND) in 3.5 mm TRRS jacks exposed to user handling. IC Role / Device Role / Timing Role: Bidirectional TVS across each audio conductor to clamp both positive and negative ESD pulses without DC bias dependency. Use Value: Blocks ±30 kV air discharge without introducing audible noise or DC offset shift, thanks to 1.8 V VRWM and symmetric clamping. | Use Scenario: Protecting RS-485 or CAN FD transceiver I/O pins in factory automation sensors subjected to cable discharge events. IC Role / Device Role / Timing Role: Secondary-level TVS on field-side signal lines where primary surge protection resides upstream. Use Value: Adds localized ±30 kV ESD hardening with 7.0 V clamping at 25A, ensuring transceiver survival during maintenance-related cable hot-plug events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ18A | Unidirectional, SMA package (4.5 mm × 2.7 mm), 18 V VRWM, 33.2 V clamping @ 25A | Requires external series resistor for bidirectional behavior; unsuitable for high-speed data lines due to >100 pF capacitance | Select only for low-frequency power rail or GPIO protection where size and speed are secondary |
| SP1003-01UTG | Bidirectional, SOD-323 package (1.7 mm × 1.25 mm), 3.3 V VRWM, 12 pF CT, ±30 kV ESD | Lower capacitance but higher VRWM - incompatible with 1.8 V logic interfaces; better for 3.3 V UART or I²C | Prefer for 3.3 V systems needing tighter clamping margin and lower parasitic loading |
Compared with SMAJ18A and SP1003-01UTG, D1V8L1BS2LP3 uniquely supports 1.8 V signal rails with sub-35 pF loading and 0.61 mm × 0.30 mm footprint - making it the only option among the three qualified for miniaturized USB 2.0 or MIPI D-PHY receiver protection.

FAQ
What is the maximum operating temperature range for D1V8L1BS2LP3?
The D1V8L1BS2LP3 is rated for operation from −55°C to +150°C, covering extended industrial and automotive cabin environments. Its thermal resistance (RθJA = 500°C/W) assumes mounting on a standard FR-4 PCB with Diodes' recommended 2 oz copper pad layout; derating applies above +25°C ambient per Figure 1 in DS43456.
Does D1V8L1BS2LP3 require orientation during PCB placement?
No - D1V8L1BS2LP3 is a fully bidirectional TVS diode with symmetrical electrical characteristics; Pin 1 and Pin 2 are functionally identical and interchangeable. The "C/C (Reversed)" marking on the top surface indicates package polarity but does not imply directional current flow or functional asymmetry.
How does the 32 pF capacitance affect USB 2.0 signal integrity?
At 32 pF, the device introduces negligible loading on USB 2.0 full-speed (12 Mbps) and high-speed (480 Mbps) signals when placed adjacent to the connector. Measured eye diagrams show <5% rise-time degradation and no measurable jitter increase, confirming compatibility with USB-IF compliance testing when used with Diodes' recommended pad layout.
Is D1V8L1BS2LP3 qualified for automotive applications?
D1V8L1BS2LP3 is not AEC-Q200 qualified out-of-the-box. While its operating temperature range (−55°C to +150°C) meets automotive under-hood requirements, Diodes states that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing - customers must contact Diodes directly to request qualification for automotive use cases.
