Product details
Overview
1N6160 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), and stable 27.5–28V clamping across temperature and current range - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the 1N6160 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge stress, low dynamic resistance (<20 mΩ), junction capacitance (175 pF at 22V), and DFN 1.6×1.6mm 6-lead package compatibility with space-constrained USB PD and IoT designs.
Technical Context
The 1N6160 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown threshold - enabling near-constant clamping voltage independent of peak pulse current magnitude. Its operation differs fundamentally from conventional TVS diodes by eliminating linear VC = VBR + IPP × RDYN dependence.
Clamping remains stable from −40°C to +125°C due to FET-based shunting, with measured VC = 27.5–28V at both 24A and 40A (1.2/50μs + 8/20μs combination waveform, RS = 2Ω), and dynamic resistance of 20 mΩ confirmed between 1A and 40A pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22 V - defines maximum continuous DC or RMS operating voltage on protected line without leakage degradation. |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge events. |
| Peak Pulse Current | 40 A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 (±1 kV, RS = 42Ω) on unsymmetrical lines. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds industrial and consumer ESD immunity requirements without derating. |
| Junction Capacitance | 175 pF at 22 V, 1 MHz - compatible with <25 MHz signal integrity budgets; not suitable for USB SS or PCIe lanes. |
| Dynamic Resistance | 20 mΩ - enables minimal voltage rise under high di/dt transients, critical for protecting low-voltage tolerance FET gates in load switches. |
Pinout & Package
1N6160 is housed in a Pb-free, RoHS-compliant DFN 1.6 mm × 1.6 mm × 0.55 mm 6-lead package with exposed thermal pad (no internal thermal pad required; energy dissipated in silicon). All pins must be connected for full 40A rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three pins must be soldered to solid ground plane with multiple vias to minimize inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS in USB PD); parallel connection of all three pins maximizes surge current handling and reduces trace inductance. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based clamping architecture | Eliminates voltage rise with increasing IPP; maintains ≤28 V clamping from 1A to 40A - unlike TVS diodes whose VC rises linearly with current. |
| Temperature-stable clamping | VC remains constant from −40°C to +125°C - avoids thermal derating and enables reliable protection in industrial ambient conditions. |
| Low dynamic resistance | 20 mΩ enables sub-1V overshoot during fast-rising surges - critical for safeguarding gate oxides in integrated load switches like HS2950P. |
| High-energy surge rating | 1120 W peak pulse power (8/20μs) supports repeated exposure to lightning-induced transients in remote metering and robotics. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
Use Scenario: Protecting VBUS line in USB-C receptacles supporting up to 20V/5A PD negotiation against ESD, lightning surges, and hot-plug transients. IC Role / Device Role / Timing Role: Primary EOS shunt device placed immediately after connector, clamping transients before reaching PD controller and port power switch. Use Value: Maintains 27.5–28V clamping across −40°C to +125°C - prevents false overvoltage shutdown and ensures robust PD negotiation under thermal stress. |
Use Scenario: Safeguarding input of programmable load switches (e.g., HS2950P) in industrial PLC modules, battery-powered meters, and robotic actuators. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage seen by internal FET gate oxide during 40A surge events. Use Value: 20 mΩ dynamic resistance prevents gate-source overvoltage during fast-rising transients - eliminates need for external gate clamp diodes. |
| IoT Edge Node Power Bus Protection | Storage Device 22V Rail Protection |
Use Scenario: Securing 22V auxiliary power rails in cellular-connected IoT gateways exposed to field ESD and induced surges via long sensor cables. IC Role / Device Role / Timing Role: Single-device solution replacing multi-stage TVS+MOV networks, reducing BOM count and PCB area by >60%. Use Value: 175 pF capacitance allows use on 24V auxiliary rails without degrading 10–25 MHz control loop stability in PMIC feedback paths. |
Use Scenario: Protecting 22V backup or auxiliary supply rails in NVMe SSD enclosures and enterprise HDD backplanes subjected to hot-swap and system-level surges. IC Role / Device Role / Timing Role: High-reliability clamping element placed at board edge to intercept transients before reaching storage controller power domains. Use Value: ±30 kV ESD rating ensures immunity to handling damage during manufacturing and field maintenance - reducing RMA rates in datacenter hardware. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Standard unidirectional TVS diode; VBR = 24.4–26.9V, VC = 35.5V @ 12.3A, RDYN ≈ 1.2Ω - clamping rises significantly with current and temperature. | Limited to lower-energy surges; requires derating above 85°C; unsuitable for 40A IEC 61000-4-5 compliance without parallel devices. | Select SMAJ22A only for cost-sensitive, low-surge environments where clamping voltage margin >8V is acceptable. |
| TPD2E007DRYR | Low-capacitance (3.5 pF) dual-channel ESD protector; VRWM = 7V, IPP = 4A - insufficient for 22V bus or 40A surge handling. | Designed for high-speed data lines (USB 2.0, HDMI), not power rail protection; lacks EOS energy absorption capability. | Use TPD2E007DRYR only for secondary ESD protection on CC/SBU lines - never as primary VBUS suppressor in place of 1N6160. |
Compared with SMAJ22A and TPD2E007DRYR, the 1N6160 delivers uniquely stable clamping under high-current and wide-temperature conditions, making it the only option among the three qualified for primary 22V power rail protection in USB PD and industrial load switch applications.

FAQ
What is the maximum continuous operating voltage for the 1N6160?
The 1N6160 has a reverse stand-off voltage (VRWM) of 22 V, meaning it can continuously block up to 22 V DC or RMS without significant leakage. This makes it suitable for 20V USB PD VBUS lines and 24V industrial auxiliary rails where nominal voltage stays within specification. Exceeding 22 V risks increased leakage and premature triggering.
Does the 1N6160 require a thermal pad on the PCB?
No, the 1N6160 does not require an external thermal pad. Unlike power MOSFETs or LDOs, its surge energy is dissipated internally in the silicon FET structure, and the DFN package is designed for direct mounting without thermal vias to inner layers. However, low-inductance grounding of pins 1–3 via multiple vias is mandatory for full 40A performance.
Can the 1N6160 be used on high-speed data lines like USB SuperSpeed?
No, the 1N6160 is not suitable for USB SuperSpeed (5 Gbps) or other high-speed differential data lines. Its 175 pF junction capacitance at 22 V would severely degrade signal integrity. For such lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25 pF), while reserving the 1N6160 strictly for power or low-frequency I/O line protection.
How does the 1N6160 achieve stable clamping voltage across temperature?
The 1N6160 achieves stable clamping by using a surge-rated FET as the conduction element, controlled by a precision trigger circuit. When triggered, the FET enters a low-RDS(on) state (<20 mΩ), causing clamping voltage to track the trigger circuit's reference voltage rather than rising with current or temperature - unlike conventional TVS diodes whose VC increases linearly with both IPP and ambient temperature.
Is the 1N6160 pin-compatible with standard SOD-123 or SMA packages?
No, the 1N6160 is exclusively offered in a DFN 1.6 mm × 1.6 mm × 0.55 mm 6-lead package and has no pin-compatible equivalents in legacy discrete packages. Its 6-pin configuration (3×GND, 3×IN) is optimized for low-inductance surge routing and cannot be substituted with 2-pin TVS diodes without redesigning layout, grounding, and current-sharing paths.
