Product details
Overview
JAN1N5550 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, 20mΩ dynamic resistance, and 175pF junction capacitance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the JAN1N5550 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, validated DFN-6 pin mapping, real-world clamping stability across temperature and current, and direct alternative options for 22V bus protection with constant-voltage surge suppression.
Technical Context
The JAN1N5550 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and rapidly turns on the shunt path. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A due to decreasing RDS(on) under surge conditions.
It operates across –40°C to +125°C with stable breakdown voltage (25–27.9V), low leakage (<600nA at 22V), and minimal temperature-dependent drift in clamping - enabling reliable protection in thermally demanding industrial and portable applications without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without triggering |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream 24V-rated ICs (e.g., USB PD controllers, load switches) remain below damage threshold |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment and USB PD systems |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements without external shielding |
| Dynamic Resistance | 20mΩ - enables flat clamping curve and minimizes voltage overshoot during fast-rising transients |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with 22V power rails but not high-speed data lines (requires separate low-C TVS for SS lanes) |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be connected to maximize current handling and minimize inductance |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBUS, load switch input); parallel connection ensures uniform current sharing and thermal distribution |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | 27.5–28V across full 24–40A surge range - eliminates need for over-specifying IPP to meet voltage limits |
| Temperature-stable protection | Clamping voltage variation <0.5V from –40°C to +125°C - enables single BOM across wide ambient ranges |
| Low dynamic resistance | 20mΩ - reduces I²R losses and localized heating during multi-pulse surge events |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive switching noise in motor drives and PLCs |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V VBUS lines in USB-C receptacles supporting up to 100W PD, exposed to ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Primary front-end EOS suppressor placed directly at connector, shunting transients before reaching PD controller and power path FETs. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents latch-up or gate oxide damage in 24V-rated PD controllers where standard TVS would exceed 35V. |
Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and factory automation. IC Role / Device Role / Timing Role: High-current transient diverter placed between power source and load switch input, limiting voltage seen by internal control FET. Use Value: Prevents overvoltage failure of load switch's integrated MOSFET by clamping to ≤28V - avoids costly field returns due to surge-induced short-circuit failures. |
| IoT Edge Node Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary rails in battery-backed IoT gateways and cellular routers subjected to ESD during field servicing and surge coupling from nearby AC lines. IC Role / Device Role / Timing Role: Standalone EOS protector on always-on 22V system rail, operating continuously across –40°C to +85°C ambient. Use Value: Delivers stable 27.5V clamping at full 40A even at 85°C - ensures consistent protection margin without thermal derating or design iteration. |
Use Scenario: Protecting 22V backup supplies in NVMe SSD enclosures and enterprise storage controllers exposed to hot-plug transients and board-level ESD. IC Role / Device Role / Timing Role: Low-inductance, high-reliability clamp on 22V standby rail feeding real-time clock and firmware retention circuitry. Use Value: 175pF capacitance avoids signal integrity issues on low-noise analog rails; 600nA max leakage preserves battery life in >1-year backup scenarios. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 22V transient protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Semtech TDS2211P | Same die, identical electrical specs and package - direct replacement with identical marking (T22) and reel packaging | No functional difference; used interchangeably in production with same layout and qualification | Select when requiring Semtech-authorized channel traceability or specific tape-and-reel compliance (e.g., J-STD-033) |
| Littelfuse SP3022-01ETG | TVS diode (not TDS architecture); 22V VRWM, 33V VC @ 24A, higher dynamic resistance (~150mΩ), clamping rises with temperature | Higher clamping voltage limits use with 24V ICs at elevated temperatures; requires larger derating margin | Choose only if legacy TVS design reuse is required and 33V clamping is acceptable for downstream components |
Compared with JAN1N5550, TDS2211P offers identical performance and sourcing continuity, while SP3022-01ETG provides lower-cost TVS-based protection at the expense of 5.5V higher clamping and reduced thermal stability - making JAN1N5550 the preferred choice for 22V systems demanding guaranteed sub-28V protection across temperature and current.

FAQ
What is the clamping voltage of JAN1N5550 at 40A surge current?
JAN1N5550 clamps at 27.5–28V under 40A peak pulse current (8/20μs waveform, 2Ω source impedance), as confirmed in the Semtech datasheet Section 2, Electrical Characteristics table. This stable clamping is enabled by its FET-based architecture and remains within ±0.5V across –40°C to +125°C ambient temperature - a key differentiator from conventional TVS diodes.
Is JAN1N5550 pin-compatible with TDS2211P?
Yes, JAN1N5550 is functionally and physically identical to TDS2211P: same DFN-6 package (1.6mm × 1.6mm), identical pinout (Pins 1–3 = GND, Pins 4–6 = IN), matching marking code (T22), and fully aligned electrical specifications including 22V working voltage, 40A surge rating, and 27.5–28V clamping. They are interchangeable in layout and BOM.
Can JAN1N5550 be used on high-speed data lines like USB SuperSpeed or PCIe?
No, JAN1N5550 is not suitable for high-speed data lines. Its 175pF junction capacitance at 22V would severely degrade signal integrity on differential pairs operating above 100MHz. It is designed exclusively for 22V power or low-frequency I/O lines. For USB SS/PCIe protection, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF).
What is the maximum operating temperature for JAN1N5550?
JAN1N5550 is rated for continuous operation from –40°C to +125°C ambient temperature, with junction temperature capability up to +150°C. Its clamping voltage and leakage current remain within specification across this full range, as validated in the Typical Characteristics plots (Pages 3–4 of the datasheet).
Does JAN1N5550 require a thermal pad or heatsink on the PCB?
No, JAN1N5550 does not require a thermal pad or external heatsink. The device dissipates surge energy through its internal FET structure, and the DFN package relies on copper area and multiple vias to ground for effective transient current handling. The datasheet explicitly states "no thermal pad is needed" under transient conditions (Page 6).
