Diodes Incorporated D4V5H1U2LP1610Q-7

Overview

D4V5H1U2LP1610Q-7 from Diodes Incorporated is a single-channel, AEC-Q101-qualified TVS diode designed for high-surge ESD protection in automotive and industrial signal lines. It delivers 5.5V reverse breakdown voltage (V_BR), clamps transients to ≤13V at 90A (8/20μs), maintains 800pF typical channel capacitance, and withstands ±30kV contact/air ESD per IEC 61000-4-2 - ideal for touch panel data lines and small-panel module interfaces.

For engineers reviewing the D4V5H1U2LP1610Q-7 datasheet, D4V5H1U2LP1610Q-7 pinout, D4V5H1U2LP1610Q-7 application, or D4V5H1U2LP1610Q-7 equivalent, key selection criteria include low clamping voltage under 90A surge, sub-1nF input capacitance for high-speed signal integrity, AEC-Q101 qualification status, U-DFN1610-2 package thermal performance, and compliance with ISO 10605 and IEC 61000-4-5 standards.

Technical Context

This unidirectional TVS diode operates as a shunt protector between signal line and ground, activating above 5.5V V_BR to divert transient energy while maintaining low dynamic resistance (0.05Ω) and minimal voltage overshoot. Its design targets fast response to ESD events (<1ns) and robust handling of repetitive ±30kV strikes without parameter drift.

The device integrates into compact PCB layouts via its 1.6mm × 1.0mm U-DFN1610-2 (Type B) package with NiPdAu-plated terminals, supporting reflow soldering per MIL-STD-202 and achieving 250°C/W junction-to-ambient thermal resistance on standard FR-4 pads. Moisture sensitivity is rated Level 1 per J-STD-020.

FAQ

What is the maximum clamping voltage of D4V5H1U2LP1610Q-7 at 90A surge current?

The clamping voltage is 13V at 90A peak pulse current (8/20μs waveform), measured cathode-to-anode under standardized IEC 61000-4-5 test conditions. This value is guaranteed across the full −55°C to +150°C operating temperature range and reflects worst-case voltage seen by protected circuitry during lightning-level surges.

Is D4V5H1U2LP1610Q-7 suitable for bidirectional signal lines like USB D+ and D−?

No - D4V5H1U2LP1610Q-7 is a unidirectional TVS diode intended for DC-biased lines referenced to ground. For bidirectional lines such as USB 2.0, two devices must be used back-to-back (anode-to-anode) or a dedicated bidirectional variant like D4V5H1U2LP1610Q-7B should be selected to ensure symmetric clamping on both polarities.

Does this part require external series impedance for optimal ESD protection?

No external resistor is required for basic ESD suppression, as the device's low dynamic resistance (0.05Ω) enables direct shunt placement. However, a 0Ω or low-value (≤10Ω) series resistor may be added near the protected IC to limit current during sustained overvoltage, improving long-term reliability in systems with frequent surge exposure.

How does the U-DFN1610-2 package affect thermal performance in continuous operation?

The U-DFN1610-2 package achieves 250°C/W junction-to-ambient thermal resistance on standard 2oz FR-4 pads, limiting continuous power dissipation to 500mW at +25°C ambient. For sustained surge duty cycles, thermal relief via copper pour under the exposed pad or adjacent ground stitching vias is recommended to maintain junction temperature below 150°C.
