Diodes Incorporated D5V0P1B2LP-7B

Overview

D5V0P1B2LP-7B from Diodes Incorporated is a bidirectional TVS diode designed for ESD protection of high-speed data lines in portable electronics. It features a 5.5 V reverse standoff voltage, 6 V minimum breakdown voltage, 8 pF typical channel capacitance, ±15 kV contact/±17 kV air ESD immunity per IEC 61000-4-2, and operates in the X1-DFN1006-2 (0.53 mm max height) package.

For engineers reviewing the D5V0P1B2LP-7B datasheet, D5V0P1B2LP-7B pinout, D5V0P1B2LP-7B application, or D5V0P1B2LP-7B equivalent, key selection criteria include low-capacitance signal-line protection, compact DFN footprint compatibility with high-density PCB layouts, IEC 61000-4-2 compliance level, clamping performance at 1A/4A pulses, and thermal derating behavior across -65°C to +150°C ambient.

Technical Context

This TVS device uses a silicon avalanche structure optimized for fast transient response (<1 ns typical turn-on) and low dynamic impedance during ESD events. Its bidirectional configuration enables symmetric clamping for AC-coupled or differential interfaces without polarity constraints.

Designed for placement directly at I/O connectors or IC pins, it delivers sub-9 V clamping at 1 A (8/20 µs) and ≤13 V at 4 A, while maintaining 10 nA max leakage at 5 V and operating within a 250 mW power dissipation limit on standard FR-4 pads.

FAQ

What is the maximum clamping voltage at 4 A for D5V0P1B2LP-7B?

The maximum clamping voltage is 13.0 V under 8/20 µs pulse conditions at 4 A peak pulse current, as specified in the Electrical Characteristics table. This value ensures downstream ICs with 13.5 V absolute maximum ratings remain safely within limits during worst-case ESD events.

Is D5V0P1B2LP-7B compatible with lead-free reflow soldering processes?

Yes. The device uses NiPdAu-plated copper leadframe terminals and is qualified per MIL-STD-202, Method 208. Its X1-DFN1006-2 package supports standard lead-free reflow profiles up to 260°C peak temperature, with moisture sensitivity level 1 requiring no dry-pack handling.

Does D5V0P1B2LP-7B require orientation-specific PCB placement?

No. As a bidirectional TVS diode, it functions identically regardless of anode/cathode orientation relative to the protected line and ground. Pin 1 (marked Q4) is not polarity-sensitive; both terminals serve symmetric clamping roles in response to positive or negative transients.

Can D5V0P1B2LP-7B be used on 3.3 V logic I/O lines?

Yes. With a 5.5 V reverse standoff voltage and 6 V minimum breakdown, it provides safe margin above 3.3 V nominal operation while maintaining <100 nA leakage at 5 V. Its low capacitance avoids signal distortion, making it suitable for protecting GPIOs, UART, and SPI lines in battery-powered systems.
