Product details
Overview
1N6102 from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance. It protects USB PD, Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the 1N6102 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternatives for 22V bus protection where low-voltage overshoot margin and thermal robustness are critical.
Technical Context
The 1N6102 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant across 0–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C with stable 27.5–28V clamping at 40A, 22V reverse stand-off, 27.9V max breakdown, and 175pF junction capacitance at 22V/1MHz - enabling reliable protection without thermal derating or clamping voltage drift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD VBus and industrial 24V rail systems without derating. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - stays below typical 28–30V damage thresholds of load switches and PD controllers. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 3 (±1kV, RS = 42Ω) for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and consumer ESD requirements. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage rise during fast transients. |
| Junction Capacitance | 175pF at 22V/1MHz - suitable for DC power rails and low-speed signal lines; not for >100MHz data paths. |
Pinout & Package
1N6102 is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder connection required). All six terminals are electrically active: three parallel input pins and three parallel ground pins for low-inductance surge conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Parallel ground connections - must all be routed to solid ground plane with multiple vias to minimize inductance during 40A surges. |
| Pins 4, 5, 6 | IN | Parallel protected-line inputs - must be short-traced directly from connector to device to avoid coupling and ensure full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables near-constant clamping voltage across 0–40A and –40°C to +125°C - eliminates thermal derating needed with TVS diodes. |
| Low dynamic resistance | 20mΩ ensures minimal IR drop during surge, maintaining clamping at ≤28V even at peak 40A current. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive burst noise in motor drives and PLCs. |
| Small-footprint DFN-6 | 1.6mm × 1.6mm area saves >60% board space vs. SO-8 or SOT-23 TVS solutions rated for comparable surge energy. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting the VBus line of a USB Type-C port supporting up to 20V/5A PD negotiation, exposed to ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Transient diverting suppressor placed at connector entry point to clamp overvoltage before reaching PD controller and power multiplexer. Use Value: Maintains 27.5–28V clamping across temperature and current - avoids false trips or damage to 28V-rated PD ICs under worst-case 40A surge at 125°C. |
Use Scenario: Safeguarding the input of an industrial-grade load switch (e.g., HS2950P) powering remote sensors or actuators in metering or robotics. IC Role / Device Role / Timing Role: Primary EOS shunt device absorbing 8/20μs surges from long cables or inductive switching, preventing gate oxide failure in the load switch's internal FET. Use Value: 20mΩ dynamic resistance limits voltage overshoot to <28V during 40A transients - staying below the 30V absolute maximum rating of common 24V load switches. |
| IoT Device DC Power Rail Protection | Tablet/Notebook VBus Line Protection |
Use Scenario: Securing the 22V input rail of a battery-powered IoT gateway connected to PoE++ or external adapters in harsh EMI environments. IC Role / Device Role / Timing Role: Standalone EOS protector on main power entry, operating alongside upstream e-fuse and downstream LDOs. Use Value: 175pF capacitance avoids signal integrity issues on DC rails, while ±30kV ESD rating ensures survivability during field handling and deployment. |
Use Scenario: Protecting the VBus line in thin-client tablets where PCB space is constrained and thermal management is limited. IC Role / Device Role / Timing Role: Compact 1.6mm × 1.6mm transient suppressor mounted adjacent to USB-C receptacle to minimize trace inductance. Use Value: Stable clamping at 28V across –40°C to +125°C eliminates need for derated selection - simplifies thermal design and BOM consolidation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Semtech TDS2211P | Same silicon die, identical electrical specs and package - direct manufacturer-recommended replacement for 1N6102 with identical marking and reel packaging. | No functional difference; used interchangeably in production for same 22V bus protection role. | Select TDS2211P when sourcing from Semtech's official distribution channel with full traceability and warranty coverage. |
| Littelfuse SP3022-01FTG | TVS diode (not FET-based); 22V working voltage, 33.6V clamping at 40A, higher dynamic resistance (~150mΩ), greater temperature sensitivity. | Higher clamping voltage reduces margin for 28V-rated ICs; requires thermal derating above 85°C. | Choose SP3022-01FTG only if FET-based architecture is not required and clamping margin >33V is acceptable. |
Compared with 1N6102, TDS2211P offers identical performance and supply chain continuity, while SP3022-01FTG trades lower cost for higher clamping voltage and reduced thermal stability - making 1N6102 optimal where consistent sub-28V protection across temperature and current is mandatory.

FAQ
What is the exact package type and footprint of the 1N6102?
The 1N6102 uses a 6-pin DFN package measuring 1.6mm × 1.6mm × 0.55mm with no thermal pad requirement. Pins 1–3 are GND; pins 4–6 are IN. Land pattern follows Semtech's recommended layout: symmetric 0.3mm pitch, 0.5mm pad length, and ≥3 vias per GND group to minimize inductance. The 1N6102 footprint is identical to TDS2211P and fully compatible with standard DFN-6 reflow profiles.
Does the 1N6102 meet IEC 61000-4-5 surge immunity requirements?
Yes, the 1N6102 is rated for 40A peak pulse current (8/20μs waveform), satisfying IEC 61000-4-5 Level 3 (±1kV, RS = 42Ω, CS = 0.5μF) for industrial equipment. Its 27.5–28V clamping at 40A ensures protected circuits remain within safe operating limits during standardized surge events - confirmed in Semtech's TDS2211P datasheet Rev 2.5, Section 2.
How does the 1N6102 differ from standard TVS diodes in clamping behavior?
Unlike PN-junction TVS diodes whose clamping voltage rises linearly with current (VC = VBR + IPP × RDYN), the 1N6102 uses a triggered FET architecture that maintains ~27.5–28V clamping from 1A to 40A and across –40°C to +125°C. This eliminates thermal derating and provides predictable protection margins - a key distinction validated in Figure 3 of the 1N6102's reference datasheet.
Can the 1N6102 be used on high-speed data lines like USB SS or PCIe?
No, the 1N6102 is not suitable for high-speed data lines. Its 175pF junction capacitance at 22V would severely degrade signal integrity on SuperSpeed (5+ Gbps), PCIe, or HDMI interfaces. It is intended exclusively for DC power rails and low-speed control lines (e.g., USB CC, SBU, or load switch enable). For data lines, Semtech recommends RClamp3371ZC (<0.25pF) alongside the 1N6102 in full USB-C protection schemes.
What is the maximum operating temperature range for the 1N6102?
The 1N6102 is specified for continuous operation from –40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range - varying by less than 0.5V from –40°C to +125°C at 40A (per Figure 3 in the datasheet). Junction temperature may reach +150°C under surge, but steady-state thermal design should maintain TA ≤ +125°C for reliability.
