Diodes Incorporated DESD5V0V1BDLP3-7

Overview

DESD5V0V1BDLP3-7 from Diodes Incorporated is a bidirectional TVS diode designed for ESD protection of high-speed data lines in portable electronics. It features 5 V reverse standoff voltage, ±17 kV contact/±19 kV air ESD immunity per IEC 61000-4-2, 5.3 pF typical input capacitance, 11.5 V clamping voltage at 0.5 A, and X2-ESN0603-2 (0201) package-ideal for USB 2.0, HDMI, and audio jack interfaces.

For engineers reviewing the DESD5V0V1BDLP3-7 datasheet, DESD5V0V1BDLP3-7 pinout, DESD5V0V1BDLP3-7 application, or DESD5V0V1BDLP3-7 equivalent, key selection criteria include low-capacitance transient suppression, bidirectional surge handling, IEC-compliant ESD robustness, and compatibility with space-constrained 0201 PCB layouts in consumer handheld devices.

Technical Context

This device operates as a low-capacitance, bidirectional clamping TVS diode with symmetrical breakdown behavior across both polarities. Its 6 V minimum breakdown voltage ensures reliable triggering above 5 V signal rails, while dynamic resistance of 2.0 Ω (TLP, 10 A) enables fast voltage limiting during sub-nanosecond ESD events.

The X2-ESN0603-2 package integrates NiAu bump terminations for solderability and thermal performance on FR-4 PCBs, supporting 250 mW steady-state power dissipation and 500 °C/W junction-to-ambient thermal resistance under standard pad layout AP02001.

FAQ

Is DESD5V0V1BDLP3-7 still in active production?

No-Diodes Incorporated has officially discontinued DESD5V0V1BDLP3-7 (as stated in DS37987 Rev. 2–4). It is marked "OBSOLETE – PART DISCONTINUED" with no alternate part offered. Aetrix Electronics maintains limited legacy stock for last-time buy and design continuity support.

What is the maximum operating temperature range for this TVS diode?

The DESD5V0V1BDLP3-7 supports an operating and storage temperature range of −65 °C to +150 °C. Its thermal resistance (RθJA = 500 °C/W) and 250 mW power dissipation rating assume use on a standard FR-4 PCB with Diodes' recommended AP02001 pad layout.

Can this device protect differential signal pairs like USB or HDMI?

Yes-its bidirectional configuration and 5.3 pF capacitance make it suitable for protecting individual lines in differential pairs. It is commonly deployed as one device per I/O line (e.g., D+, D−, CLK, DATA0–3), not across the pair, preserving common-mode noise rejection.

How does the 6 V breakdown voltage relate to its 5 V standoff rating?

The 5 V reverse standoff voltage (VRWM) defines the maximum DC voltage the device blocks with ≤100 nA leakage. The 6 V minimum breakdown voltage (VBR) is the threshold at which it begins conducting significantly (1 mA test current), providing margin to avoid false triggering during normal operation.
