Product details
Overview
ESDA8P30-1T2 from STMicroelectronics is a unidirectional single-line transient voltage suppressor (TVS) diode designed for ESD and EOS protection on power lines. It delivers 300 W peak pulse power (8/20 µs), clamps at 11 V @ 20 A and 12 V @ 30 A, features 6.3 V stand-off voltage and 170 pF line capacitance, and is used in USB Vbus, battery, and portable device power rail protection.
For engineers reviewing the ESDA8P30-1T2 datasheet, ESDA8P30-1T2 pinout, ESDA8P30-1T2 application, or ESDA8P30-1T2 equivalent, key selection criteria include clamping voltage under 30 A surge, low leakage (<0.3 µA @ 25 °C), IEC 61000-4-2 Level 4 compliance (±30 kV contact/air), and SOD882T footprint compatibility with high-density PCB layouts.
Technical Context
This TVS diode operates as a unidirectional clamping device with a breakdown voltage of 6.9–7.8 V (1 mA test current) and dynamic resistance of 0.12 Ω, enabling fast response to ESD transients while limiting voltage overshoot. Its low 170 pF line-to-line capacitance ensures minimal signal distortion on DC power rails like USB Vbus.
The device meets IEC 61000-4-2 Level 4 with ±30 kV air and contact discharge capability, and its thermal design supports continuous operation from –55 °C to +150 °C junction temperature, making it suitable for compact, thermally constrained mobile power interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage | 6.3 V - Maximum continuous operating voltage before conduction begins; defines safe DC bias margin for USB Vbus (5 V nominal) and battery lines. |
| Breakdown Voltage | 7.3 V (typ.) @ 1 mA - Threshold where device enters avalanche conduction; ensures reliable triggering above system operating voltage. |
| Clamping Voltage | 12 V @ 30 A (8/20 µs) - Peak voltage seen by protected circuit during worst-case surge; limits stress on downstream ICs. |
| Peak Pulse Power | 300 W (8/20 µs) - Energy-handling capacity for short-duration ESD/EOS events; enables robust protection without derating in handheld devices. |
| Leakage Current | 0.3 µA @ 25 °C - Negligible standby power loss; critical for battery-powered systems with multi-year shelf life requirements. |
| Line Capacitance | 170 pF @ 1 MHz - Low enough to avoid signal integrity degradation on 5 V DC rails; avoids resonance or filtering effects on power paths. |
| ESD Rating | ±30 kV (IEC 61000-4-2, contact & air) - Full Level 4 immunity; eliminates need for secondary protection layers in certified consumer designs. |
Pinout & Package
SOD882T ultra-small surface-mount package (1.0 × 0.6 × 0.4 mm), optimized for space-constrained mobile PCBs. Dual-pin configuration with cathode marking on Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to protected line (e.g., USB Vbus); polarity defines unidirectional clamping from line to GND. |
| Pin 2 | Anode | Connected to system ground; completes clamping path during ESD event; requires low-inductance GND plane routing. |
Key Features
| Feature | Design Value |
|---|---|
| Low Clamping Voltage | 12 V @ 30 A ensures protected ICs (e.g., USB PHY, PMIC) remain within absolute maximum ratings during surge. |
| High Surge Current Rating | 30 A (8/20 µs) supports repeated ESD strikes without parameter shift or failure in field-deployed devices. |
| Ultra-Low Leakage | 0.3 µA @ 25 °C minimizes quiescent current drain-critical for always-on battery monitoring circuits. |
| Compact SOD882T Footprint | 0.6 mm width enables placement adjacent to connectors without compromising board real estate in smartphones and wearables. |
Applications
| USB Vbus Protection | Battery Terminal Protection |
|---|---|
Use Scenario: Protecting USB Type-C or micro-B Vbus lines against hot-plug ESD and load-dump transients in portable chargers and accessories. IC Role / Device Role / Timing Role: Unidirectional TVS clamping device placed between Vbus and GND, triggered within <1 ns of ESD onset.

| Smartphone Power Rail Protection | Portable Multimedia DC Input Protection |
Use Scenario: Shielding main PMIC input rails (e.g., 5 V buck converter input) from ESD coupling via buttons, SIM trays, or charging ports. IC Role / Device Role / Timing Role: Primary front-end TVS on high-current DC input path; coordinates with downstream ceramic capacitors for sub-100 ns response. Use Value: Enables 100% pass rate on IEC 61000-4-2 Level 4 testing without redesigning power delivery network. | Use Scenario: Securing 5 V/12 V DC inputs of Bluetooth speakers, wireless headphones, and portable projectors against user-handling ESD. IC Role / Device Role / Timing Role: Low-capacitance (170 pF) clamping element placed directly at barrel jack or USB-C port entry point. Use Value: Maintains audio signal purity and prevents reset glitches in DSPs by avoiding capacitive loading on supply rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | DO-214AC package (4.5 × 2.7 mm); 5.0 V stand-off; 100 W Ppp; higher clamping (11.2 V @ 10 A) | Larger footprint; lower surge rating; suited for industrial power supplies, not space-constrained mobile designs | Select when board area is unconstrained and 5 V rail protection requires higher IEC margin at lower cost. |
| TPD1E05U06DPYR | 0201 package (0.6 × 0.3 mm); 5.5 V stand-off; 120 W Ppp; 10 pF capacitance; bidirectional | Lower capacitance but lower surge rating; bidirectional conduction unsuitable for DC-biased power rails | Choose only for signal-line ESD protection; not recommended for Vbus/battery due to stand-off mismatch and bidirectional behavior. |
Compared with SMAJ5.0A and TPD1E05U06DPYR, ESDA8P30-1T2 uniquely balances 300 W surge capability, 6.3 V stand-off, and SOD882T size-making it optimal for high-reliability, space-limited power rail protection where unidirectional clamping and ±30 kV ESD immunity are mandatory.

FAQ
What is the polarity configuration of ESDA8P30-1T2?
ESDA8P30-1T2 is a unidirectional TVS diode with Pin 1 as cathode and Pin 2 as anode. It conducts only when the protected line (connected to Pin 1) exceeds the stand-off voltage relative to ground (Pin 2), making it suitable for DC-biased power rails like USB Vbus and battery+.
Does ESDA8P30-1T2 require external biasing or control signals?
No. ESDA8P30-1T2 is a passive device that operates automatically based on voltage threshold. It remains non-conductive below 6.3 V and clamps transients above breakdown voltage without any external circuitry, power supply, or enable signal.
Can ESDA8P30-1T2 be used on data lines such as USB D+/D−?
No. With 170 pF line capacitance, ESDA8P30-1T2 introduces excessive signal distortion on high-speed differential data lines. It is specified exclusively for DC power rail protection (e.g., Vbus, battery+, 5 V/12 V inputs), not signal integrity-critical interfaces.
What is the maximum continuous DC voltage this device can withstand?
The maximum continuous DC voltage is the stand-off voltage: 6.3 V. Operation above this level risks premature conduction and thermal runaway. It is rated for 5 V nominal systems (e.g., USB) with margin for ripple and tolerance; do not use on 12 V or higher rails.
