Product details
Overview
ESDA17P20-1F2 from STMicroelectronics is a unidirectional single-line TVS diode designed for ESD and EOS protection on power lines, featuring 15 V stand-off voltage, 25 A peak pulse current (8/20 µs), 23 V clamping voltage at 20 A, 190 pF line capacitance, and 0.25 Ω dynamic resistance - deployed in space-constrained USB buses and battery lines.
For engineers reviewing the ESDA17P20-1F2 datasheet, ESDA17P20-1F2 pinout, ESDA17P20-1F2 application, or ESDA17P20-1F2 equivalent, key selection criteria include IEC 61000-4-2 Level 4 compliance (±30 kV contact/air), low-leakage operation (80 nA @ 25 °C), thermal robustness (Tj max = 150 °C), and 0402 CSP footprint compatibility with high-density PCB layouts.
Technical Context
This TVS diode operates as a clamping device triggered by transient overvoltage events exceeding its 15.6–17.9 V breakdown range, delivering sub-23 V clamping up to 20 A while maintaining low dynamic impedance (0.25 Ω) to minimize voltage overshoot during fast ESD pulses (IEC 61000-4-2, 30 kV).
Its 190 pF line capacitance and unidirectional configuration support DC-biased power rail protection without signal distortion, and its 0402 CSP package enables integration into ultra-compact portable electronics where board area and parasitic capacitance are critical constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage | 15 V - maximum continuous operating voltage before conduction begins |
| Breakdown Voltage | 15.6–17.9 V @ 1 mA - precise triggering threshold for transient suppression |
| Clamping Voltage | 23 V @ 20 A (8/20 µs) - limits downstream voltage stress during surge events |
| Peak Pulse Current | 25 A (8/20 µs) - withstands high-energy transients per IEC 61000-4-2 |
| Line Capacitance | 190 pF @ 1 MHz - minimizes signal integrity impact on high-speed power rails |
| Leakage Current | 80 nA @ 15 V, 25 °C - ensures negligible standby power loss in battery-powered systems |
| Dynamic Resistance | 0.25 Ω - reduces clamping voltage rise under high di/dt conditions |
Pinout & Package
The ESDA17P20-1F2 is housed in a 0402 Chip Scale Package (CSP) with two terminals: anode and cathode. The cathode is marked with a bar on the top surface per Figure 10 of DS13369 Rev 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | DO-214AC package (3.5 × 1.6 mm), 15 V VRWM, 24.4 V VCL @ 22.5 A | Higher mounting height and PCB area; suited for non-space-constrained industrial boards | Select when board layout allows larger footprint and higher surge rating is prioritized over capacitance |
| TPD1E10B06DPYR | 0402 DFN, 5.5 V VRWM, 12 V VCL @ 4 A, 0.6 pF CL | Lower voltage rating and clamping; optimized for high-speed data lines, not power rails | Choose only for low-voltage signal-line protection where <1 pF capacitance is mandatory |
Compared with SMAJ15A and TPD1E10B06DPYR, ESDA17P20-1F2 uniquely balances 15 V standoff, 25 A surge capability, and 190 pF capacitance in a 0402 CSP-making it optimal for compact, battery-fed power rail protection where moderate capacitance is acceptable and board area is premium.

FAQ
What is the maximum clamping voltage of ESDA17P20-1F2 under IEC 61000-4-2 testing?
The ESDA17P20-1F2 achieves a clamping voltage of 20.6 V when subjected to an 8 kV contact discharge per IEC 61000-4-2, measured at 30 ns after pulse initiation. At higher surge currents (20 A, 8/20 µs), its specified clamping voltage is 23 V - verified in DS13369 Rev 2 Table 2.
Can ESDA17P20-1F2 be used on bidirectional signal lines?
No. The ESDA17P20-1F2 is a unidirectional TVS diode, intended only for DC-biased lines like power rails. Its asymmetrical IV curve does not provide symmetric clamping for AC or bidirectional signals; using it on such lines risks forward conduction during normal operation or inadequate negative-going transient suppression.
What is the recommended reflow profile for ESDA17P20-1F2?
ST specifies a peak reflow temperature of 240–245 °C for 60 seconds (maximum 90 s), with ramp rates of ≤2 °C/s pre-peak and ≤3 °C/s cooling. The profile must comply with IPC/JEDEC J-STD-020, and air convection should be minimized to prevent component movement due to its 0.54 mg mass and fine-pitch 0402 CSP geometry.
Does ESDA17P20-1F2 meet RoHS and REACH requirements?
Yes. The ESDA17P20-1F2 is manufactured in ST's ECOPACK-compliant processes and meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full compliance documentation, including substance declarations and test reports, is accessible via ST's official product page and ECOPACK portal at www.st.com.
