Product details
Overview
TESDU12V RGG from Taiwan Semiconductor is a bi-directional ESD protection diode in 0603 package, rated for 12 V working voltage, ±15 kV air/±8 kV contact ESD immunity per IEC 61000-4-2, 33 V clamping voltage at 5 A peak pulse current, and 15 pF junction capacitance - deployed to safeguard USB 2.0 data lines in portable instrumentation.
For engineers reviewing the TESDU12V RGG datasheet, TESDU12V RGG pinout, TESDU12V RGG application, or TESDU12V RGG equivalent, key selection criteria include clamping voltage under 5 A surge, low capacitance for high-speed signal integrity, RoHS-compliant green compound packaging, and compatibility with reflow soldering at 260°C/10s.
Technical Context
This device implements a single-channel, bi-directional TVS structure optimized for transient suppression on I/O lines. It features gold-plated terminals compliant with MIL-STD-705 Method 2026 and operates across –55°C to +150°C junction temperature range.
The TESDU12V RGG delivers 25 W peak pulse power (8/20 µs waveform), reverse stand-off voltage of 12 V, breakdown voltage ≥13 V at 1 mA, and reverse leakage ≤25 µA at VR = 12 V - enabling robust protection without signal distortion in space-constrained layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 12 V - defines maximum continuous DC operating voltage before leakage increases significantly |
| Clamping Voltage (IPP = 5 A) | 33 V - limits transient voltage seen by downstream IC during 5 A ESD event, protecting 3.3 V/5 V logic |
| Junction Capacitance | 15 pF at 0 V, 1 MHz - low enough to avoid signal degradation on USB 2.0 (480 Mbps) lines |
| ESD Rating (IEC 61000-4-2) | ±15 kV air, ±8 kV contact - exceeds industrial immunity requirements for handheld interfaces |
| Package | 0603 (1.6 × 0.8 mm) - enables placement adjacent to connectors with minimal PCB area |
| Moisture Sensitivity Level | MSL 1 - allows unlimited floor life and standard reflow without baking |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (positive polarity) | Conducts surge current toward ground when positive ESD event occurs on protected line |
| Cathode | Transient current entry point (negative polarity) | Conducts surge current toward ground when negative ESD event occurs - enables bi-directional clamping |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional ESD protection | Single-device solution for ± polarity transients on one I/O line, eliminating need for dual-diode arrays |
| Low clamping voltage | 33 V at 5 A ensures downstream 12 V-rated ICs remain within safe operating area during surge |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A | Unidirectional, higher clamping (36.6 V @ 5 A), larger SMA package (4.5 × 2.7 mm) | Requires external series resistor for bi-directional use; unsuitable for high-density USB routing | Prefer TESDU12V RGG where board space and bidirectionality are critical |
| ESD9B12VD | Bi-directional, same 0603 size, but 36 V clamping @ 5 A and 20 pF capacitance | Higher capacitance may degrade USB 2.0 eye diagram; lower surge rating (12 W) | Choose TESDU12V RGG for tighter clamping and higher pulse power in portable designs |
Compared with SMAJ12A and ESD9B12VD, the TESDU12V RGG provides superior combination of bi-directional operation, 33 V clamping, 15 pF capacitance, and 25 W surge capability in 0603 - making it optimal for space-limited, high-speed I/O protection where signal fidelity and compact layout are mandatory.

FAQ
What is the maximum clamping voltage of the TESDU12V RGG at 5 A peak pulse current?
The TESDU12V RGG has a maximum clamping voltage of 33 V at 5 A peak pulse current (8/20 µs waveform). This value is measured under standardized surge conditions and ensures downstream 12 V-rated components remain within safe operating limits during ESD events. The clamping performance is guaranteed across the full operating temperature range of –55°C to +150°C.
Is the TESDU12V RGG bi-directional or unidirectional?
The TESDU12V RGG is a bi-directional ESD protection diode, designed to suppress both positive and negative polarity transients on a single I/O line without requiring external biasing. Its symmetrical IV characteristic enables direct placement across data lines like USB D+/D– or touch panel electrodes, distinguishing it from unidirectional alternatives such as SMAJ12A.
What is the junction capacitance of the TESDU12V RGG and why does it matter?
The TESDU12V RGG exhibits 15 pF junction capacitance at 0 V and 1 MHz. This low value minimizes signal distortion and preserves edge integrity on high-speed interfaces such as USB 2.0 (480 Mbps), ensuring compliance with eye diagram and jitter specifications. Higher capacitance would attenuate high-frequency components and increase bit error rates.
Does the TESDU12V RGG comply with RoHS and halogen-free standards?
Yes, the TESDU12V RGG complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. Its green compound packaging and gold-plated terminals meet environmental and reliability requirements for consumer, industrial, and medical-grade portable electronics.
What is the recommended PCB layout practice for the TESDU12V RGG?
Place the TESDU12V RGG within 2 mm of the protected connector or I/O pad, with minimal trace length to ground. Use a solid ground plane beneath the device, avoid vias in the protection path, and keep the return path short to reduce inductance. These practices ensure effective transient energy shunting and prevent coupling into adjacent signal lines.
