Product details
Overview
UESD6.0DT5G from onsemi is a unidirectional ESD protection diode in SOT-723 package, featuring 6.0 V working peak reverse voltage, 7.0 V minimum breakdown voltage at 1.0 mA, 34 pF typical capacitance at 0 V, <1 ns response time, and IEC61000-4-2 Level 4 (±30 kV air/±30 kV contact) ESD rating - deployed for high-density USB, HDMI, and audio line protection in smartphones and wearables.
For engineers reviewing the UESD6.0DT5G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage under 12 V at 1 A IPP, low-leakage operation (<0.1 µA at 6.0 V), AEC-Q101 qualification, and ultra-compact 1.20 mm × 0.80 mm footprint with 0.5 mm height.
Technical Context
This device implements a single-channel unidirectional TVS structure optimized for signal-line ESD suppression. It operates with a defined cathode-anode polarity, exhibits stable breakdown behavior from −55 °C to +150 °C, and maintains sub-34 pF capacitance across 0–5 V bias - critical for preserving high-speed signal integrity.
Clamping performance is characterized at 1 A peak pulse current (8/20 µs waveform), delivering VC ≤ 12.0 V while sustaining 16 kV HBM ESD immunity. Its thermally robust SOT-723 package supports MSL 1 handling and 260 °C reflow compatibility without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| ESD Rating | ±30 kV air / ±30 kV contact per IEC61000-4-2 Level 4 - meets industrial and portable product compliance requirements |
| Leakage Current | ≤0.1 µA @ 6.0 V - ensures minimal power drain in battery-powered standby modes |
| Response Time | <1 ns - guarantees protection activation before sensitive transceivers are damaged |
Pinout & Package
SOT-723 (Case 631AA, Style 4) is a 3-terminal surface-mount package measuring 1.20 mm × 0.80 mm × 0.50 mm with 0.40 mm lead pitch. Terminals are co-planar, matte tin-plated, and rated for 260 °C reflow.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UESD5.0DT5G | Lower VRWM (5.0 V) and VBR (6.2 V); 38 pF capacitance | Better suited for 3.3 V logic rails; slightly higher capacitance may affect >480 Mbps signaling | Select when protecting 3.3 V I/O with tighter voltage margin and acceptable ~12% higher C |
| ESD9B5.0ST5G | Same SOT-723 package; bidirectional; 5.0 V VRWM; 25 pF capacitance | Supports AC-coupled lines (e.g., USB Type-C CC pins); lower capacitance improves RF immunity | Choose for symmetric transients or where bidirectional clamping is required, accepting reduced HBM rating (12 kV) |
Compared with UESD5.0DT5G and ESD9B5.0ST5G, the UESD6.0DT5G offers highest working voltage headroom for 5 V systems, lowest capacitance among unidirectional SOT-723 options, and strongest IEC61000-4-2 rating - making it optimal for high-reliability 5 V interface protection where space and ESD margin are constrained.

FAQ
What is the maximum clamping voltage of UESD6.0DT5G under standard ESD test conditions?
The UESD6.0DT5G has a maximum clamping voltage (VC) of 12.0 V when subjected to a 1 A peak pulse current with an 8/20 µs waveform. This value is measured per IEC61000-4-2 test methodology and ensures safe operation for 5 V-tolerant ICs. The UESD6.0DT5G maintains this clamping performance across its full operating temperature range of −55 °C to +150 °C.
Is UESD6.0DT5G suitable for protecting bidirectional signal lines like USB D+ and D−?
Yes, UESD6.0DT5G is configured as a unidirectional diode but is commonly used in pairs - one device per line - with cathodes tied to the signal and anodes grounded. This arrangement provides effective protection for bidirectional data lines such as USB 2.0 D+ and D−, as confirmed in onsemi's application guidance for the ESD3.3DT5G Series. Each UESD6.0DT5G handles transient polarity appropriate to its placement.
Does UESD6.0DT5G meet automotive qualification standards?
Yes, UESD6.0DT5G is AEC-Q101 qualified and PPAP capable, confirming its suitability for automotive applications including infotainment, telematics, and ADAS sensor interfaces. The device undergoes stress testing for temperature cycling, humidity, mechanical shock, and ESD robustness per AEC-Q101 Rev D. Full qualification documentation is available through onsemi's automotive product portal.
What is the thermal resistance and power derating behavior of UESD6.0DT5G?
UESD6.0DT5G has a junction-to-ambient thermal resistance (RJA) of 525 °C/W on FR-5 board. Its steady-state power dissipation is rated at 240 mW at TA = 25 °C, derating linearly by 1.9 mW/°C above that temperature. This derating curve is validated per Figure 4 in the official datasheet and supports reliable operation up to +150 °C junction temperature.
Can UESD6.0DT5G be used in place of UESD3.3DT5G without circuit redesign?
No - UESD6.0DT5G is not a drop-in replacement for UESD3.3DT5G due to its higher 6.0 V working voltage and different breakdown threshold (7.0 V vs. 5.0 V). Substituting it on a 3.3 V rail risks insufficient clamping margin during normal operation. Circuit validation is required if changing from UESD3.3DT5G to UESD6.0DT5G, especially regarding leakage, signal integrity, and transient response under actual system-level ESD stress.
