Product details
Overview
ESDA8P80-1U1M from STMicroelectronics is a unidirectional transient voltage suppressor (TVS) diode designed for I/O or power line ESD and EOS protection in space-constrained applications. It features 6.3 V stand-off voltage, 1.0 µA reverse leakage at VRM, 7.3 V typical breakdown voltage at 1 mA, 13.2 V clamping voltage at 80 A (8/20 µs), and 480 pF line capacitance - optimized for USB Type-C Vbus and USB-PD up to 20 V protection.
For engineers reviewing the ESDA8P80-1U1M datasheet, ESDA8P80-1U1M pinout, ESDA8P80-1U1M application, or ESDA8P80-1U1M equivalent, key selection criteria include clamping performance under 80 A surge, low dynamic resistance (0.06 Ω), thermal stability up to 150 °C junction temperature, and QFN-2L footprint compatibility with high-density PCB layouts.
Technical Context
This TVS diode operates as a single-line unidirectional clamp, with anode-cathode configuration enabling fast turn-on during ESD transients (IEC 61000-4-2 ±30 kV contact/air) and lightning surges (IEC 61000-4-5, 8/20 µs up to 120 A). Its low dynamic resistance (0.06 Ω) ensures minimal voltage overshoot during high-current events.
The device uses silicon avalanche structure with controlled doping and geometry to deliver stable clamping across -55 °C to +150 °C operating junction temperature, with negligible derating up to Tj = 150 °C - critical for automotive and industrial power rail protection where thermal margin is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VRM) | 6.3 V - maximum continuous reverse voltage before leakage exceeds 1.0 µA; sets safe operating margin below protected line's nominal voltage (e.g., 5 V or 9 V rails). |
| Breakdown Voltage (VBR) | 7.3 V typ. at 1 mA - precise avalanche onset ensures predictable triggering without premature conduction during normal operation. |
| Clamping Voltage (VCL) | 13.2 V at 80 A (8/20 µs) - limits transient overvoltage to safe levels for downstream ICs such as USB-PD controllers or battery management ICs. |
| Dynamic Resistance (RD) | 0.06 Ω - low impedance during surge enables efficient energy shunting and minimizes voltage rise ΔV = RD × IPP. |
| Line Capacitance (CI/O-GND) | 480 pF at 1 MHz - balances ESD robustness with signal integrity for DC-biased lines like USB Vbus, avoiding excessive bandwidth degradation. |
| ESD Rating | ±30 kV contact & air discharge (IEC 61000-4-2 Level 4) - exceeds industrial and medical equipment immunity requirements without external filtering. |
| Surge Rating | 120 A (8/20 µs, IEC 61000-4-5) - supports lightning-induced transients on power inputs in harsh environments including industrial and medical systems. |
Pinout & Package
ESDA8P80-1U1M is housed in a compact QFN-2L package measuring 1.6 mm × 1.0 mm × 0.55 mm (height), with exposed pad for thermal dissipation and solderable terminals on opposite edges. The 75% smaller footprint versus SOD-123FL enables high-density routing in portable and miniaturized designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected line (e.g., USB Vbus); conducts during positive transients when cathode is grounded or referenced to lower potential. |
| Pin 2 | Cathode | Connected to ground or low-impedance return path; establishes unidirectional clamping direction and defines reference for stand-off and breakdown behavior. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional Clamping Architecture | Enables precise protection of positive-only power rails (e.g., Vbus) without reverse conduction risk or signal distortion on bidirectional data lines. |
| Low Dynamic Resistance (0.06 Ω) | Reduces clamping voltage overshoot under high-current surges, preserving voltage margin for 5 V–20 V system components. |
| 150 °C Maximum Junction Temperature | Supports operation in thermally demanding environments (e.g., enclosed medical enclosures or industrial power modules) without derating loss. |
| ECOPACK2 ROHS Compliance & MSL Level 1 | Enables lead-free reflow assembly without moisture sensitivity concerns, eliminating bake requirements and supporting automated high-volume manufacturing. |
| 480 pF Line Capacitance | Minimizes impact on DC power rail impedance while maintaining robust ESD immunity - suitable for USB-PD 20 V charging paths. |

FAQ
What is the maximum continuous reverse voltage rating for ESDA8P80-1U1M?
The maximum continuous reverse voltage (stand-off voltage) is 6.3 V, defined as VRM - the highest DC or RMS voltage that can be continuously applied without exceeding 1.0 µA reverse leakage current. This rating ensures safe operation on 5 V or 9 V power rails while maintaining sufficient margin before avalanche conduction begins.
How does ESDA8P80-1U1M perform under high-temperature operating conditions?
ESDA8P80-1U1M maintains full specified performance from -55 °C to +150 °C junction temperature, with no derating required up to Tj = 150 °C. Its low dynamic resistance (0.06 Ω) and stable clamping voltage (13.2 V at 80 A) remain consistent across this range, validated per JESD22-A108 and IEC 61000-4-5 thermal cycling protocols.
Can ESDA8P80-1U1M be used for bidirectional signal line protection?
No - ESDA8P80-1U1M is strictly unidirectional and must be connected with Pin 1 (anode) to the protected line and Pin 2 (cathode) to ground. For bidirectional data lines (e.g., USB D+/D− or HDMI), a symmetric dual-diode array or dedicated bidirectional TVS (e.g., ESDALYV5-1U1M) is required to prevent forward conduction during negative transients.
Is the QFN-2L package of ESDA8P80-1U1M compatible with standard reflow profiles?
Yes - the device complies with J-STD-020 MSL Level 1 and is qualified for standard lead-free reflow profiles, including ST's recommended 240–245 °C peak temperature profile with ≤60 s above 220 °C. Its ECOPACK2 construction eliminates moisture sensitivity concerns, enabling direct placement without pre-bake.
