Product details
Overview
ESDA8V2-1J from STMicroelectronics is a unidirectional Transil™ TVS diode designed for EOS and ESD protection of single-line power supply inputs in portable electronics, featuring 8.2 V breakdown voltage, 500 W peak pulse power (8/20 µs), 30 kV contact ESD immunity per IEC 61000-4-2 Level 4, <0.5 µA leakage at 5 V, and 210–250 pF input capacitance - deployed in cellular handset battery/charger ports.
For engineers reviewing the ESDA8V2-1J datasheet, ESDA8V2-1J pinout, ESDA8V2-1J application, or ESDA8V2-1J equivalent, this device serves as a low-capacitance, high-power transient suppressor optimized for space-constrained DC power rail protection where fast clamping (<11 V @ 1 A), robust MIL-STD-883G Class 3B HBM (>8 kV), and SOD-323 footprint compatibility are critical.
Technical Context
The ESDA8V2-1J operates as a unidirectional avalanche diode with sharp reverse-breakdown onset at 8.2 V (IR = 1 mA), clamping transients to ≤20 V at 25 A (8/20 µs). Its junction capacitance remains stable at 210–250 pF (VR = 0 V, 1 MHz), enabling minimal signal distortion on low-speed power lines.
It meets IEC 61000-4-2 Level 4 (±15 kV air / ±8 kV contact) and MIL-STD-883G Method 3015-7 Class 3B (≥8 kV HBM), with thermal derating down to 0.5× PPP at 125 °C junction temperature - confirming suitability for thermally demanding portable environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 8.2 V @ 1 mA - defines precise overvoltage trip threshold for protected IC supply rails |
| Peak Pulse Power | 500 W (8/20 µs) - sustains high-energy surges without failure in handheld charger interfaces |
| Clamping Voltage | ≤11 V @ 1 A - limits downstream IC stress during ESD events on battery lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.5A | Higher 8.5 V VBR, SMA package (4.5 × 2.7 mm), 400 W PPP | Larger footprint; lower power density; less suitable for ultra-compact designs | Select when board space allows larger package and higher VBR tolerance is acceptable |
| TPD1E05U06DPYR | Lower 5.5 V VBR, 0.5 pF capacitance, 12 V clamping @ 1 A, DFN-2 | Optimized for high-speed data lines (USB 2.0), not power rail clamping | Prefer only for signal-line ESD protection; unsuitable for 5 V power rail due to premature conduction |
Compared with SMAJ8.5A and TPD1E05U06DPYR, ESDA8V2-1J uniquely balances 8.2 V precision breakdown, 500 W surge capacity, and SOD-323 miniaturization - making it optimal for space-limited, high-energy DC power port protection where clamping voltage and leakage must be tightly controlled.

FAQ
What is the maximum clamping voltage of ESDA8V2-1J at 25 A?
The ESDA8V2-1J clamps to ≤20 V at 25 A under an 8/20 µs exponential pulse, as specified in Table 3 of ST's Doc ID 15646 Rev 1. This value ensures protected ICs experience no more than 20 V stress during worst-case surge events, well below typical 24 V absolute maximum ratings of PMICs and battery monitors.
Is ESDA8V2-1J bidirectional or unidirectional?
ESDA8V2-1J is explicitly unidirectional, as confirmed in its datasheet description and functional diagram. It protects only positive-going transients on a DC line referenced to ground - forward-biased during normal operation and avalanche-clamping during overvoltage. Bidirectional variants (e.g., ESDAL series) are separate part numbers.
Can ESDA8V2-1J be used on data lines like USB D+/D−?
No - with 210–250 pF capacitance, ESDA8V2-1J introduces excessive signal loading on high-speed data lines. It is intended solely for DC power rail protection (e.g., VBUS, BAT+, 3.3 V/5 V supplies). For USB 2.0, use low-capacitance alternatives like TPD1E05U06DPYR (0.5 pF).
Does ESDA8V2-1J meet automotive AEC-Q200 requirements?
No - ESDA8V2-1J is not qualified to AEC-Q200. Its datasheet specifies operation from −40 to +125 °C but lacks stress test reports, qualification documentation, or automotive-grade marking. For automotive infotainment or telematics power ports, select ST's AEC-Q200-qualified SMAJ or TRANSIL™ A series parts.
