Product details
Overview
D8V0H1B2LP-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, 20A peak pulse current (8/20μs), 55pF typical capacitance, ±30kV IEC61000-4-2 contact/air discharge rating, and clamps to ≤17.5V at 20A - enabling robust protection in space-constrained mobile and touch panel systems.
For engineers reviewing the D8V0H1B2LP-7B datasheet, D8V0H1B2LP-7B pinout, D8V0H1B2LP-7B application, or D8V0H1B2LP-7B equivalent, key selection criteria include low clamping voltage under high surge, sub-1mm DFN package compatibility with fine-pitch PCB layouts, and verified IEC61000-4-2 compliance without derating at +85°C ambient.
Technical Context
This device operates as a symmetrical, two-terminal transient voltage suppressor with no polarity dependence. Its silicon avalanche structure provides fast response (<1ns) to ESD transients and stable clamping across temperature (–65°C to +150°C), supported by a thermal resistance of 500°C/W on standard FR-4 layout.
The X1-DFN1006-2 package integrates NiPdAu-plated terminals and green molding compound (UL 94V-0), enabling reflow soldering per MIL-STD-202 Method 208 while maintaining moisture sensitivity level 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 8.5V min @ 1mA - ensures reliable conduction onset before downstream IC damage thresholds. |
| Clamping Voltage (VCL) | 17.5V max @ 20A, 8/20μs - limits transient overvoltage to safe levels for 3.3V/5V interface ICs. |
| Capacitance (CT) | 55pF typ @ 0V, 1MHz - preserves signal integrity on low-speed lines (≤10Mbps) without distortion. |
| ESD Rating | ±30kV air & contact (IEC61000-4-2) - meets highest industrial and consumer immunity requirements. |
| Peak Pulse Power | 350W @ 8/20μs - sustains multiple high-energy surges without parametric shift or failure. |
| Leakage Current | 200nA max @ 8.0V - avoids loading on battery-powered or high-impedance sensor nodes. |
Pinout & Package
Package: X1-DFN1006-2 (1.00 × 0.60 × 0.50 mm), surface-mount, dual-terminal, bottom-exposed thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode/Cathode (bidirectional) | Identical terminal function - either pin serves as input/output for transient suppression path. |
| Pin 2 | Anode/Cathode (bidirectional) | Electrically symmetric to Pin 1; no polarity marking required in circuit layout. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating lines without polarity constraints. |
| Low-profile DFN package | 1.00 × 0.60 mm footprint saves >60% board area vs. SOD-323, critical for compact touch modules. |
| High surge robustness | 20A IPP rating supports repeated lightning-surge-like events (IEC61000-4-5) without degradation. |
| Lead-free & halogen-free | Complies with RoHS 3 (2015/863/EU) and automotive "Green" definitions (<900ppm Br/Cl, <1000ppm Sb). |
Applications
| Mobile Device Power Line Protection | Capacitive Touch Panel Interface |
|---|---|
Use Scenario: Protecting USB VBUS and battery charge enable lines in smartphones against user-hand ESD. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector entry point to shunt transients before PMIC inputs. Use Value: Prevents latch-up or gate oxide damage in 3.3V/5V PMICs using only 55pF loading and 17.5V clamping at full 20A surge. |
Use Scenario: Shielding I²C or GPIO lines connecting host MCU to touch controller IC in OLED display modules. IC Role / Device Role / Timing Role: Low-capacitance ESD clamp on bidirectional data/control lines with no signal inversion or timing skew. Use Value: Maintains signal rise/fall times below 10ns while surviving ±30kV contact discharge per IEC61000-4-2. |
| Small Panel Module Control Lines | Industrial Human-Machine Interface (HMI) |
Use Scenario: Safeguarding reset, interrupt, and enable signals in compact LCD driver boards used in wearables. IC Role / Device Role / Timing Role: Standalone ESD protector on 1.8V/3.3V logic-level control paths with minimal board real estate. Use Value: 200nA leakage prevents battery drain in always-on sleep modes; 0.5mm height fits under thin bezels. |
Use Scenario: Hardening push-button and encoder inputs on factory-floor HMIs exposed to frequent operator ESD events. IC Role / Device Role / Timing Role: Primary line-level protection before microcontroller GPIOs, rated for industrial temperature range (–40°C to +85°C). Use Value: 350W peak power dissipation enables operation without thermal shutdown during repetitive 20A surges. |
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 | Unidirectional, DO-214AC package (4.5 × 2.7 mm), 100pF capacitance, 10.0V VBR min | Requires external polarity management; unsuitable for AC-coupled or floating lines | Select only when unidirectional protection suffices and board space allows larger footprint. |
| TPD2E001DRYR | 2-channel, 12pF/channel, 12V VBR, 4A IPP, X2SON-6 package | Higher channel count but lower surge rating; optimized for high-speed USB 2.0, not power lines | Prefer for multi-line data buses where ultra-low capacitance outweighs single-line surge capability. |
Compared with SMAJ8.0A and TPD2E001DRYR, D8V0H1B2LP-7B uniquely balances 20A surge handling, 55pF capacitance, and 1.0×0.6mm size in a polarity-agnostic configuration - making it optimal for space-limited, single-line power/control protection where both ESD and lightning-surge immunity are required.

FAQ
What is the maximum operating temperature for D8V0H1B2LP-7B?
The device operates from –65°C to +150°C junction temperature. Derating begins above +25°C ambient: power dissipation drops linearly to zero at +150°C, per Figure 1 in DS40919 Rev. 2–2. At +85°C ambient, it retains ~65% of its 250mW rated power.
Can D8V0H1B2LP-7B be used on 12V power rails?
No - its 8.0V reverse standoff voltage (VRWM) and 8.5V minimum breakdown make it unsuitable for 12V systems. Clamping begins near 10V and exceeds 12V at low currents; use higher-VBR variants like D12V0H1B2LP-7B for 12V rail protection.
Does this TVS require a ground connection?
No - D8V0H1B2LP-7B is a two-terminal, bidirectional device. It connects between the protected line and system ground (or another reference plane) to shunt transients; no separate bias or enable pin is needed.
How does its 55pF capacitance affect USB 2.0 signal integrity?
At 480Mbps, USB 2.0 eye diagrams tolerate up to ~10–15pF per line for full compliance. With 55pF, D8V0H1B2LP-7B is not recommended for D+/D− data lines; it is intended for VBUS, ID, or control lines where bandwidth is ≤10MHz and signal integrity impact is negligible.
