Product details
Overview
ESDA17P100-1U2M from STMicroelectronics is a unidirectional single-line transient voltage suppressor (TVS) diode designed for high-power ESD and EOS protection on VBUS power lines. It delivers 4800 W peak pulse power (8/20 µs), clamps at 24–30 V under 100–160 A surges, features 15 V stand-off voltage, 1200 pF capacitance at 1 MHz, and meets IEC 61000-4-2 Level 4 (±30 kV contact/air discharge). It is deployed in USB VBUS lines of smartphones and portable devices.
For engineers reviewing the ESDA17P100-1U2M datasheet, ESDA17P100-1U2M pinout, ESDA17P100-1U2M application, or ESDA17P100-1U2M equivalent, key selection criteria include clamping voltage at 160 A, dynamic resistance (0.07 Ω), leakage current (<200 nA at 15 V), µQFN package footprint compatibility, and compliance with IEC 61000-4-2 Level 4 ESD immunity requirements.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging avalanche breakdown to divert ESD/EOS transients from sensitive downstream circuitry. Its low dynamic resistance (0.07 Ω) ensures minimal voltage overshoot during fast 8/20 µs pulses, while its 1200 pF junction capacitance is optimized for VBUS line protection without compromising signal integrity in DC-coupled power paths.
The device is rated for continuous operation from –55 °C to +150 °C, with thermal derating of peak pulse power above 25 °C confirmed by Figure 2 in DS11998. Its µQFN package integrates pins 5, 6, and the exposed thermal tab as common GND connections-critical for low-inductance surge return path design in compact mobile PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage | 15 V - Maximum continuous DC operating voltage before leakage exceeds 200 nA; defines safe VBUS operating margin. |
| Breakdown Voltage | 15.7–17.7 V @ 1 mA - Ensures reliable triggering before system overvoltage damage occurs. |
| Clamping Voltage | 24–30 V @ 100–160 A (8/20 µs) - Limits transient voltage seen by protected ICs to safe levels during ESD events. |
| Peak Pulse Power | 4800 W (8/20 µs) - Sustains high-energy surges without failure; enables robust protection in noisy environments. |
| Junction Capacitance | 1200 pF @ 0 V, 1 MHz - Matches typical USB VBUS line impedance; avoids excessive filtering or startup delay. |
| Leakage Current | ≤200 nA @ 15 V, 25 °C - Minimizes standby power loss and prevents battery drain in always-on portable systems. |
| ESD Rating | ±30 kV (IEC 61000-4-2, contact & air) - Exceeds industrial and consumer immunity requirements for handheld electronics. |
Pinout & Package
The ESDA17P100-1U2M uses a 6-pin µQFN package (1.8 × 2.0 mm, 0.55 mm height) with an exposed thermal pad (TAB) for enhanced heat dissipation and low-inductance grounding. Pin 1 is marked with a dot; pins 5, 6, and TAB are internally connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VBUS | Main power line input terminal; connects directly to protected VBUS trace prior to load switch or PMIC. |
| 2, 3, 4 | NC | No internal connection; must remain unconnected on PCB to avoid parasitic coupling or solder bridging. |
| 5, 6 | GND | Dedicated ground terminals; require low-inductance routing to system ground plane for effective surge shunting. |
| TAB | GND | Exposed thermal pad; must be soldered to solid copper pour for thermal stability and lowest possible clamping impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Low clamping voltage | 24 V @ 100 A enables protection of 3.3 V/5 V logic rails downstream of USB power switches without overvoltage stress. |
| High peak pulse power | 4800 W supports repeated ESD strikes in production test and field use without parameter shift or degradation. |
| Ultra-low leakage | 0.2 µA max at 25 °C preserves battery life in always-connected portable devices with multi-week standby requirements. |
| µQFN space efficiency | 1.8 × 2.0 mm footprint saves >40% board area vs. SO-8 or SOD-123 alternatives while maintaining thermal performance. |
| IEC 61000-4-2 Level 4 compliance | ±30 kV contact/air rating eliminates need for external ESD test margining in final product validation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | DO-214AC package; 15 V standoff; 30.5 V clamping @ 10.3 A; 400 W peak power | Lower surge rating suits lower-cost consumer accessories, not high-reliability mobile VBUS lines | Select when board space is unconstrained and peak current remains below 20 A |
| SP1003-01UTG | SOD-323 package; 14 V standoff; 25 V clamping @ 5 A; 350 W peak power; 120 pF capacitance | Lower capacitance ideal for high-speed data lines, but insufficient for 160 A VBUS surge handling | Prefer for USB data line ESD protection, not power rail duty |
Compared with SMAJ15A and SP1003-01UTG, the ESDA17P100-1U2M uniquely combines 4800 W surge capacity, 15 V standoff, and µQFN packaging-enabling high-power VBUS protection in space-constrained mobile designs where lower-power alternatives would fail under IEC 61000-4-2 Level 4 testing.

FAQ
What is the maximum continuous reverse voltage the ESDA17P100-1U2M can withstand?
The device has a stand-off voltage (VRM) of 15 V, meaning it blocks up to 15 V DC in reverse bias with leakage ≤200 nA. This value is verified per Table 2 in DS11998 and defines the maximum steady-state voltage across the diode during normal operation without triggering conduction.
Can ESDA17P100-1U2M be used on bidirectional signal lines like USB D+/D–?
No-it is a unidirectional TVS diode intended only for DC power lines such as VBUS. Bidirectional signal lines require symmetrical clamping devices (e.g., ESDALC6V1 or ESDA6V1) with matched positive/negative breakdown characteristics to avoid distorting differential signaling.
How does the µQFN package affect thermal performance during repeated ESD events?
The exposed thermal tab (TAB) and dual GND pins (5, 6) provide low thermal resistance to PCB copper, enabling rapid heat dissipation. Per Figure 2 in DS11998, peak pulse power derates to ~6000 W at 25 °C but remains >4000 W up to 100 °C junction temperature-ensuring consistent clamping under sustained surge conditions.
Is the 1200 pF capacitance problematic for USB 2.0 or USB 3.2 Gen 1 power delivery?
No-capacitance is measured at 0 V bias and 1 MHz, relevant to low-frequency surge impedance, not high-speed data integrity. USB power delivery operates at DC or kHz-level switching; this capacitance does not couple into D+/D– lines and has no impact on eye diagram or jitter in compliant implementations.
