Product details
Overview
D8V0H1B2LPQ-7B from Diodes Incorporated is a bidirectional TVS diode designed for ESD protection of single-line interfaces in low-speed data, control, and power lines. It delivers 8.5V minimum breakdown voltage, 19A peak pulse current (8/20µs), 55pF typical capacitance, and ±30kV IEC61000-4-2 contact/air discharge rating-used in touch panels and mobile device I/O protection.
For engineers reviewing the D8V0H1B2LPQ-7B datasheet, D8V0H1B2LPQ-7B pinout, D8V0H1B2LPQ-7B application, or D8V0H1B2LPQ-7B equivalent, key selection criteria include clamping voltage (20V at 19A), low leakage (<200nA at 8V), AEC-Q101 qualification, X1-DFN1006-2 package compatibility, and thermal resistance (500°C/W).
Technical Context
This device operates as a bidirectional transient voltage suppressor with symmetrical clamping behavior across both polarities. Its silicon avalanche structure enables fast response to ESD transients while maintaining low dynamic impedance during surge events.
The X1-DFN1006-2 package supports high-density PCB layouts with minimal parasitic capacitance (55pF) and thermal resistance (500°C/W). It is rated for continuous operation from –65°C to +150°C and meets automotive-grade reliability requirements per AEC-Q101.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 8.5V min - ensures reliable conduction onset before downstream IC damage in overvoltage events |
| Clamping Voltage (VCL) | 20V max at 19A - limits voltage seen by protected circuit during worst-case lightning surge (IEC61000-4-5) |
| Peak Pulse Current (IPP) | 19A @ 8/20µs - sustains high-energy transients without failure in industrial or automotive environments |
| Capacitance (CT) | 55pF @ 0V, 1MHz - preserves signal integrity on low-speed control/data lines (e.g., I²C, GPIO) |
| ESD Rating | ±30kV air/contact - exceeds IEC61000-4-2 Level 4 for robust system-level ESD immunity |
| Leakage Current (IRM) | <200nA @ 8V - prevents battery drain and false triggering in always-on portable applications |
Pinout & Package
Package: X1-DFN1006-2 (1.00 × 0.60 × 0.50 mm), lead-free, halogen-free, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode / Line Terminal | Connects to protected signal line (e.g., USB D+, I²C SDA); bidirectional conduction path |
| Pin 2 | Cathode / Line Terminal | Second terminal of symmetric TVS structure; no polarity marking required for bidirectional operation |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating lines without polarity concerns |
| Low clamping voltage | 20V at 19A ensures protected ICs remain within absolute maximum ratings during surge |
| Small footprint | 1.00mm × 0.60mm area saves space on compact mobile and wearable PCBs |
| AEC-Q101 qualification | Validated for automotive infotainment, body electronics, and ADAS sensor interfaces |
Applications

|---|---|
Use Scenario: ESD events on capacitive touch sensor traces during user interaction. IC Role / Device Role / Timing Role: Bidirectional TVS diode placed between touch controller I/O and panel electrodes. Use Value: 55pF capacitance avoids signal distortion; ±30kV ESD rating prevents false touches or controller latch-up. | Use Scenario: Transient surges on VBUS or battery input lines in smartphones and tablets. IC Role / Device Role / Timing Role: Primary overvoltage clamp on low-voltage DC supply rails (e.g., 5V, 3.3V). Use Value: 20V clamping at 19A protects PMICs and LDOs without requiring additional series impedance. |
| Automotive Control Signal Lines | Industrial Sensor Interface Protection |
Use Scenario: ESD exposure on LIN bus or switch inputs in cabin modules. IC Role / Device Role / Timing Role: Point-of-entry protection on unidirectional/bidirectional control lines. Use Value: AEC-Q101 qualification ensures reliability under temperature cycling and vibration stress. | Use Scenario: Lightning-induced surges on 4–20mA or RS-485 sensor links in factory automation. IC Role / Device Role / Timing Role: Secondary surge suppression stage after primary gas discharge tube or MOV. Use Value: 350W peak power dissipation handles multiple 8/20µs pulses without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | DO-214AC package (4.5×2.7mm), 100pF capacitance, 27.7V clamping at 12.3A | Larger footprint; higher clamping voltage; suited for board-level primary protection | Select when higher surge energy handling is needed and board space permits larger package |
| TPD2E001DRYR | SON-6 package, dual-channel, 12pF per line, 12V clamping at 4A | Lower capacitance and clamping; optimized for high-speed USB/USB-C data lines | Select for differential high-speed interfaces where <15pF is mandatory and dual-line protection is required |
Compared with SMAJ8.0A and TPD2E001DRYR, D8V0H1B2LPQ-7B uniquely balances ultra-small size (1.0×0.6mm), low clamping (20V), and automotive qualification-making it optimal for space-constrained, safety-critical single-line protection where 55pF capacitance is acceptable.

FAQ
What is the maximum operating temperature for D8V0H1B2LPQ-7B?
The device operates continuously from –65°C to +150°C, with derated power dissipation above +25°C per Figure 1 in the datasheet. At +125°C ambient, its usable power drops to ~125mW due to thermal resistance of 500°C/W on standard FR-4 layout.
Does D8V0H1B2LPQ-7B require orientation during PCB placement?
No-its bidirectional structure means either terminal can connect to the protected line or ground reference. Pin 1 marking ('PI') identifies the anode side but does not affect functional symmetry; orientation only matters for consistent assembly traceability.
How does the 55pF capacitance impact signal integrity?
At 55pF, the device is suitable for signals up to ~10MHz (e.g., I²C, SPI, GPIO, LIN). It introduces negligible rise-time degradation on 3.3V/5V control lines but is not recommended for USB 2.0 or HDMI where sub-10pF is typically required.
Is D8V0H1B2LPQ-7B compliant with automotive PPAP requirements?
Yes-it is AEC-Q101 qualified, manufactured in IATF 16949 certified facilities, and PPAP capable. Diodes provides full documentation including test reports, process flow diagrams, and control plans upon request for automotive program integration.
