Product details
Overview
SESD7L5.0DT5G from onsemi is an ultra-low-capacitance unidirectional ESD protection diode designed for high-speed signal line protection in space-constrained applications. It delivers 0.5 pF typical capacitance, 5.0 V stand-off voltage, and clamps to ≤10.4 V at 1 A peak pulse current, making it ideal for USB 2.0 high-speed and antenna line interfaces.
For engineers reviewing the SESD7L5.0DT5G datasheet, pinout, applications, or equivalent options, key selection criteria include IEC 61000-4-2 Level 4 compliance (±10 kV contact), sub-1 ns response time, bi-directional effective capacitance of 0.25 pF, low leakage (<1.0 µA), and SOT-723 package compatibility with high-density PCB layouts.
Technical Context
The SESD7L5.0DT5G implements a single-channel unidirectional TVS structure optimized for signal integrity preservation. Its 0.5 pF capacitance (measured pin1–pin3 and pin2–pin3) and 10.4 V clamping voltage at 1 A ensure minimal distortion on high-frequency lines while meeting IEC 61000-4-2 Level 4 ESD immunity requirements.
It operates within −55 °C to +150 °C junction temperature range, supports reflow up to 260 °C, and is qualified to AEC-Q101 for automotive use. The device uses a Pb-free matte tin lead finish and meets UL 94 V-0 flammability rating in its void-free thermosetting plastic SOT-723 package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD7L5.0DT1G | Same electrical specs; differs only in packaging - 3000-unit tape-and-reel vs. 8000-unit reel for SESD7L5.0DT5G | Identical functional use; selected based on production volume and feeder compatibility | Choose SESD7L5.0DT5G for high-volume SMT lines requiring longer reels to reduce changeover frequency |
| CM1213A-04SO | Higher capacitance (1.0 pF), higher clamping (12 V), SOIC-8 package (3.9 × 4.9 mm) | Targeted at lower-frequency industrial I/O rather than high-speed data lines | Select CM1213A-04SO only when board space allows larger footprint and signal bandwidth is below 100 MHz |
Compared with ESD7L5.0DT1G, SESD7L5.0DT5G offers identical protection performance with optimized reel quantity for automated assembly; versus CM1213A-04SO, it provides half the capacitance and 20% lower clamping in a package occupying <5% of the area - critical for mobile and automotive RF-sensitive designs.

FAQ
What is the primary function of the SESD7L5.0DT5G?
The SESD7L5.0DT5G is a unidirectional ESD protection diode designed to safeguard voltage-sensitive ICs from electrostatic discharge damage. It operates by clamping transient voltages to ≤10.4 V during ±10 kV IEC 61000-4-2 events while maintaining only 0.5 pF capacitance - ensuring minimal impact on high-speed signal integrity. Its SOT-723 package and dual-cathode pinout make SESD7L5.0DT5G especially suited for protecting USB 2.0, antenna, and MIPI D-PHY lines.
Does the SESD7L5.0DT5G support bi-directional signal lines?
Yes - although the SESD7L5.0DT5G is a unidirectional device, its pin configuration (pins 1 and 2 as cathodes, pin 3 as anode) allows it to protect one bi-directional line with an effective capacitance of 0.25 pF. This is achieved by connecting the protected line between pins 1 and 2, referencing pin 3 to ground. The resulting symmetric clamping behavior makes SESD7L5.0DT5G suitable for antenna feedlines and other AC-coupled interfaces where polarity reversal occurs.
What is the maximum operating temperature range for the SESD7L5.0DT5G?
The SESD7L5.0DT5G has a junction temperature range of −55 °C to +150 °C and a storage temperature range of −55 °C to +150 °C. It is rated for reflow soldering up to 260 °C for 10 seconds and meets MSL 1 moisture sensitivity requirements - meaning it can be stored indefinitely at ambient conditions without baking. These specifications confirm SESD7L5.0DT5G's suitability for under-hood automotive and industrial environments where thermal extremes are common.
Is the SESD7L5.0DT5G qualified for automotive applications?
Yes - the SESD7L5.0DT5G is AEC-Q101 qualified and PPAP capable, confirming its reliability for automotive electronics including infotainment systems, ADAS sensors, and body control modules. Its Pb-free construction, UL 94 V-0 package, and guaranteed performance across −40 °C to +125 °C ambient (derived from its −55 °C to +150 °C junction range) meet stringent automotive qualification requirements. The "S" prefix variant (e.g., SESD7L5.0DT5G) denotes automotive-grade traceability and process controls.
How does the SESD7L5.0DT5G compare to standard TVS diodes in terms of capacitance?
The SESD7L5.0DT5G delivers 0.5 pF typical capacitance - significantly lower than conventional TVS diodes, which typically range from 10 pF to several hundred pF. This ultra-low value enables use on high-speed digital and RF lines where even small parasitic capacitance degrades signal rise/fall times or causes impedance mismatch. For example, SESD7L5.0DT5G's 0.5 pF allows clean 480 Mbps USB 2.0 signaling, whereas a 10 pF TVS would distort the eye diagram. Its design prioritizes signal fidelity over surge energy handling - a deliberate trade-off for interface protection.
