Product details
Overview
D6V3E1U2LP-7B from Diodes Incorporated is a unidirectional transient voltage suppression (TVS) diode designed for ESD protection of single I/O lines in portable electronics. It features a 6.5V minimum breakdown voltage, 25A peak pulse current (8/20µs), 200pF typical junction capacitance, and ±30kV IEC 61000-4-2 contact/air discharge rating - deployed in cellular handsets to safeguard USB or audio interface pins.
For engineers reviewing the D6V3E1U2LP-7B datasheet, D6V3E1U2LP-7B pinout, D6V3E1U2LP-7B application, or D6V3E1U2LP-7B equivalent, key selection criteria include clamping voltage at 25A (≤12V), ultra-low profile (0.53mm max height), DFN1006-2 package compatibility, and RoHS/halogen-free compliance for high-density PCB layouts.
Technical Context
This TVS operates as a unidirectional clamp between I/O and ground, triggering above 6.5V reverse breakdown to divert ESD transients. Its low 200pF capacitance minimizes signal distortion on high-speed lines like USB 2.0 or audio codecs, while the 9.0–12.0V clamping range at 20–25A ensures safe voltage limiting during surge events.
The device uses a silicon avalanche structure in a lead-free, halogen-free DFN1006-2 package with NiPdAu-plated terminals. Thermal resistance is 500°C/W (junction-to-ambient), and power derating begins above 25°C ambient per Figure 1 - critical for sustained operation in thermally constrained handheld enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 6.3V maximum reverse working voltage - ensures no leakage conduction during normal 5V/3.3V I/O operation |
| VBR (min) | 6.5V at 1mA - defines earliest activation threshold for ESD clamping |
| VCL @ 25A | 10.5–12.0V (8/20µs) - limits voltage seen by protected IC during worst-case surge |
| IPP | 25A peak pulse current - withstands IEC 61000-4-5 lightning surge (line-to-ground) |
| CT | 200pF at 0V, 1MHz - preserves signal integrity on data lines up to ~100MHz |
| ESD Rating | ±30kV contact & air (IEC 61000-4-2) - exceeds industrial immunity requirements |
| PPP | 300W peak pulse power (8/20µs) - supports multi-pulse ESD event robustness |
Pinout & Package
Supplied in X1-DFN1006-2 package: 1.08mm × 0.68mm footprint, 0.53mm max height, 2-terminal surface-mount outline with exposed thermal pad not present (standard DFN-2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected I/O line; forward-biased during positive transients |
| Pin 2 | Cathode | Connected to system ground; provides low-impedance path for ESD current return |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile | 0.53mm max height - enables use under mechanical shields and in slim bezel designs |
| Low capacitance | 200pF typical - avoids signal rise-time degradation on USB 2.0 or I²S interfaces |
| High ESD immunity | ±30kV contact/air - eliminates need for secondary board-level protection in consumer handsets |
| Green construction | Halogen- and antimony-free, RoHS 3 compliant - meets global environmental compliance mandates |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | DO-214AC package (4.5×2.7mm), 6.0V VRWM, 30A IPP, 400pF CT | Higher capacitance limits use to DC/low-speed lines only; larger footprint consumes >4× PCB area | Select when higher surge rating is needed and board space permits larger package |
| TPD1E10B06DPYR | 0.6×0.3mm DFN-2, 6.0V VRWM, 12A IPP, 0.9pF CT | Lower clamping voltage (6.5V @ 1A) but insufficient for IEC 61000-4-2 ±30kV full compliance | Select only for low-energy ESD environments where sub-1pF capacitance is mandatory |
Compared with SMAJ6.0A and TPD1E10B06DPYR, D6V3E1U2LP-7B uniquely balances ±30kV compliance, 200pF capacitance, and 1.08×0.68mm footprint - making it optimal for space-constrained, high-immunity portable I/O protection.

FAQ
What is the polarity configuration of D6V3E1U2LP-7B?
D6V3E1U2LP-7B is a unidirectional TVS diode: Pin 1 is anode (connect to protected line), Pin 2 is cathode (connect to ground). It conducts only during negative transients relative to ground, making it suitable for DC-biased I/O lines like USB or audio where reverse voltage must be blocked during normal operation.
Does D6V3E1U2LP-7B meet automotive AEC-Q200 requirements?
No. D6V3E1U2LP-7B is not AEC-Q200 qualified. It is rated for -65°C to +150°C operating temperature and RoHS 3 compliance, but lacks the stress testing, failure analysis, and qualification documentation required for automotive-grade deployment. For AEC-Q200 applications, consider Diodes' AP7165 series or similar qualified TVS devices.
Can D6V3E1U2LP-7B protect bidirectional analog signals like headset jacks?
Yes, when used in unidirectional configuration with proper biasing: connect cathode to ground and anode to the signal line. Its low leakage (<1µA at 6.3V) prevents DC offset, and 200pF capacitance introduces negligible attenuation below 1MHz - sufficient for mono/stereo audio paths. For true bidirectional protection, a dual-channel device or back-to-back configuration is required.
What is the recommended PCB pad layout for D6V3E1U2LP-7B?
Use Diodes' documented X1-DFN1006-2 pad layout: 0.70mm length (C), 0.30mm width (G), 0.40mm solder mask opening (X), with 1.10mm center-to-center spacing (X1) and 0.70mm width (Y). Avoid thermal relief on pads; ensure solid copper pour beneath for optimal heat dissipation during surge events, per DS41197 suggested layout.
