Diodes Incorporated DRTR5V0U4TS-7

Overview

DRTR5V0U4TS-7 from Diodes Incorporated is a 4-channel, low-capacitance TVS diode array for ESD protection of high-speed data lines, featuring 1.0 pF typical I/O-to-GND capacitance, ±25 kV contact/±30 kV air ESD rating per IEC 61000-4-2, and 5.5 V reverse standoff voltage - deployed in USB 2.0, HDMI, and Serial ATA interfaces.

For engineers reviewing the DRTR5V0U4TS-7 datasheet, DRTR5V0U4TS-7 pinout, DRTR5V0U4TS-7 application, or DRTR5V0U4TS-7 equivalent, key selection criteria include channel count, clamping voltage at 1A (10.0 V), dynamic resistance (0.9 Ω), thermal resistance (417 °C/W), and TSOT26 package compatibility with high-density PCB layouts.

Technical Context

This device implements four bidirectional TVS diodes in a single TSOT26 package, each configured between an I/O line and GND, with no internal connection to V_CC. It operates as a passive clamp without biasing requirements, relying on avalanche breakdown above 6.0 V (V_BR) to shunt transients.

Its low 1.0 pF I/O-to-GND capacitance and 0.6 pF I/O-to-I/O capacitance preserve signal integrity up to 480 Mbps (USB 2.0), while clamping voltages of 10.0 V (positive, 1 A) and –1.7 V (negative, 1 A) limit stress on downstream PHY circuitry during ESD events.

FAQ

Is DRTR5V0U4TS-7 still in active production?

No - DRTR5V0U4TS-7 is officially obsolete and discontinued by Diodes Incorporated, with no alternate part offered. Aetrix Electronics maintains limited legacy stock for design continuity and repair programs but does not offer long-term supply assurance.

What is the function of Pin 6 (V_CC) on DRTR5V0U4TS-7?

Pin 6 is not internally connected to any circuitry and serves no functional role. The datasheet explicitly states it is unused; it may be left floating or tied to GND for mechanical stability, but must never be connected to a voltage rail.

Can DRTR5V0U4TS-7 protect both positive and negative ESD transients?

Yes - each channel is bidirectional, with symmetrical clamping: +10.0 V at 1 A for positive transients and –1.7 V at 1 A for negative transients (I/O to GND), meeting IEC 61000-4-2 requirements for both polarity discharge events.

How does the 0.6 pF I/O-to-I/O capacitance impact differential signaling?

The 0.6 pF coupling between adjacent I/O pins introduces negligible common-mode noise and preserves differential impedance; measured TLP and eye diagram data (AN77) confirm no measurable jitter or amplitude loss in USB 2.0 applications at full speed.
