Product details
Overview
1N6162AUS 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, USB Type-C VBus, and load switch inputs in industrial and portable electronics.
For engineers reviewing the 1N6162AUS 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 EOS-critical bus protection designs.
Technical Context
The 1N6162AUS 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 24–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
It operates from −40°C to +125°C with stable 27.5–28V clamping up to 125°C, 22V reverse stand-off voltage, and 175pF junction capacitance at 22V/1MHz - enabling robust protection without signal integrity compromise in high-speed power buses.
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 30V damage threshold of common load switches and PD controllers. |
| Peak Pulse Current | 40A (8/20μs) - satisfies IEC 61000-4-5 Level 4 surge immunity requirements for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds Class 4 ESD immunity for exposed connectors and ports. |
| Dynamic Resistance | 20mΩ - enables low-voltage-drop shunting, minimizing thermal stress and voltage overshoot during transients. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for DC power rails but not suitable for high-speed data lines (e.g., USB SS). |
| Operating Temperature | −40°C to +125°C - supports extended-range operation in automotive under-hood and industrial control environments. |
Pinout & Package
1N6162AUS is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with UL 94V-0 molding compound. All six terminals are surface-mount; no thermal pad required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to minimize inductance and maximize 40A capability. |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBus); parallel connection ensures uniform current sharing and optimal clamping performance. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables flat clamping voltage vs. current curve - avoids voltage runaway seen in standard TVS diodes. |
| Temperature-stable clamping | 27.5–28V clamping maintained from −40°C to +125°C - eliminates derating for high-temp industrial deployments. |
| Low dynamic resistance | 20mΩ ensures minimal IR drop during 40A surges - reduces localized heating and improves reliability. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns) - protects against repetitive fast transients in motor drives and PLCs. |
| Small-footprint DFN-6 | 1.6mm × 1.6mm area saves >60% board space vs. SO-8 TVS solutions - critical for compact USB-C and IoT modules. |
Applications
| USB 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 in notebooks and docking stations. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at the connector to clamp lightning-induced surges and ESD before reaching the PD controller and load switch. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents overvoltage damage to downstream SiP PD controllers rated ≤30V. |
Use Scenario: Safeguarding the input of an industrial-grade load switch (e.g., HS2950P) in remote metering or robotics power management. IC Role / Device Role / Timing Role: Primary EOS protection device placed upstream of the load switch FET to limit gate-source and drain-source overvoltage during surge events. Use Value: Prevents latch-up or permanent failure of the internal MOSFET by holding clamping voltage below 30V - extending system uptime in harsh EMC environments. |
| IoT Device Power Rail Protection | Storage Device 24V Backup Supply Protection |
Use Scenario: Securing the main 22V input rail of a battery-backed smart sensor node deployed in outdoor industrial gateways. IC Role / Device Role / Timing Role: Standalone EOS protector for unregulated DC input, handling both ESD and 1kV/42Ω IEC 61000-4-5 surges. Use Value: Delivers 40A surge handling in <1.6mm² footprint - enabling compact, sealed enclosures without external heat sinking. |
Use Scenario: Protecting the 22V backup supply line feeding NVMe SSDs or RAID controllers in enterprise storage arrays. IC Role / Device Role / Timing Role: High-reliability transient suppressor ensuring uninterrupted power delivery during AC line transients or hot-swap events. Use Value: Stable 27.5V clamping across temperature eliminates need for voltage margining - preserving tight 22V ±10% supply tolerance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Identical functional specification, same DFN-6 package, identical pinout and marking code T22 - confirmed as direct replacement per Semtech documentation. | Same use cases: USB PD, load switch, industrial 22V rails. | Select TDS2211P when requiring Semtech's official part number with full traceability and documented qualification data. |
| SMAJ22A | Standard unidirectional TVS diode; 22V standoff, 35.5V clamping at 13.9A (8/20μs); higher clamping, lower IPP, no temperature stability. | Limited to lower-energy surges; unsuitable for 40A or high-temp industrial use. | Choose SMAJ22A only for cost-sensitive, non-critical 22V protection where clamping voltage margin >8V is acceptable. |
Compared with TDS2211P, 1N6162AUS offers identical performance and form factor - it is a Semtech-marketed variant with identical electrical behavior and layout compatibility. Against SMAJ22A, 1N6162AUS provides 2.9× higher surge current rating, 8V lower clamping, and stable performance across temperature - making it essential for mission-critical 22V bus protection.

FAQ
What is the exact package type and dimensions of the 1N6162AUS?
The 1N6162AUS is packaged in a 6-pin DFN (Dual Flat No-lead) case measuring 1.6mm × 1.6mm × 0.55mm. It features three GND pins (1–3) and three IN pins (4–6), with no exposed thermal pad. The package is Pb-free, halogen-free, and RoHS/WEEE compliant, with UL 94V-0 flammability rating.
Does the 1N6162AUS meet IEC 61000-4-5 surge immunity standards?
Yes, the 1N6162AUS is rated for 40A peak pulse current (8/20μs waveform) and ±1kV (1.2/50μs voltage, 8/20μs current, RS = 42Ω) per IEC 61000-4-5. Its 27.5–28V clamping voltage at 40A ensures compliance with Level 4 industrial surge requirements when properly laid out near the protected connector.
How does the 1N6162AUS differ from standard TVS diodes like SMAJ22A?
The 1N6162AUS uses a triggered FET shunt architecture instead of a pn-junction diode, delivering flat clamping voltage (27.5–28V) across 24–40A and −40°C to +125°C. In contrast, SMAJ22A exhibits rising clamping (up to 35.5V) with current and temperature - making 1N6162AUS superior for high-reliability 22V bus protection.
Can the 1N6162AUS be used on high-speed data lines such as USB SuperSpeed?
No, the 1N6162AUS is not suitable for USB SuperSpeed (SS), DP, or DM lines due to its 175pF junction capacitance at 22V. It is intended exclusively for DC power or low-frequency I/O lines. For high-speed data lines, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF).
Is the 1N6162AUS pin-compatible with the TDS2211P?
Yes, the 1N6162AUS is functionally and physically identical to the TDS2211P: same DFN-6 package, identical pin configuration (GND on pins 1–3, IN on pins 4–6), matching electrical specs, and shared marking code T22. It is a Semtech-branded variant with full drop-in compatibility.
