Product details
Overview
JAN1N5420 from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection on 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 DFN 1.6×1.6mm 6-lead package - deployed in USB Type-C PD input protection.
For engineers reviewing the JAN1N5420 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance for consistent voltage limiting, ground and input terminal configuration for PCB layout, and compatibility with 22V bus systems requiring industrial surge compliance.
Technical Context
The JAN1N5420 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events. Unlike conventional TVS diodes, it achieves near-constant clamping voltage due to the FET's decreasing RDS(on) under surge conditions.
It operates across –40°C to +125°C, maintains ≤28V clamping from 24A to 40A (1.2/50μs + 8/20μs combination waveform, RS = 2Ω), and delivers 1120W peak pulse power while exhibiting only 175pF junction capacitance at 22V and 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave) - ensures downstream 22V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (tp = 8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge requirements for 22V systems. |
| Dynamic Resistance | 20mΩ - enables flat clamping response across current range, minimizing voltage rise with increasing IPP. |
| Junction Capacitance | 175pF at VR = 22V, f = 1MHz - low enough for minimal signal distortion on DC-biased power rails, not suitable for high-speed data lines. |
| ESD Withstand | ±30kV contact & air per IEC 61000-4-2 - exceeds standard human-body model requirements for front-panel or connector-facing protection. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground connection - all three must be soldered to maximize surge current path and minimize parasitic inductance. |
| Pins 4, 5, 6 | IN | Protected line input - connected in parallel to 22V bus or load switch input; all three pins carry full surge current during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | FET-based shunt delivers stable 27.5–28V clamping from 24A to 40A - eliminates voltage creep seen in TVS diodes under rising current. |
| Temperature-stable clamping | Clamping voltage remains ≤28V across –40°C to +125°C - enables reliable protection in industrial ambient conditions without derating. |
| Low dynamic resistance | 20mΩ measured between 1A and 40A (8/20μs) - reduces IR drop during surge, preserving margin for downstream 22V-rated components. |
| High-energy surge rating | 1120W peak pulse power (8/20μs) - supports repeated exposure to IEC 61000-4-5 ±1kV (RS = 42Ω) transients on 22V lines. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBus lines in USB Type-C receptacles supporting up to 20V PD, exposed to ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at connector, shunting EOS energy to ground before reaching PD controller or load switch. Use Value: Maintains ≤28V clamping at 40A and 125°C - prevents latch-up or gate oxide damage in 22V-tolerant PD controllers where conventional TVS would exceed 35V. |
Use Scenario: Safeguarding enable or input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and IoT edge nodes. IC Role / Device Role / Timing Role: Primary front-end surge clamp on VIN rail, protecting internal FET gate oxide and overvoltage protection circuitry. Use Value: Limits transient voltage to <28V during 40A 8/20μs surges - avoids destructive breakdown of load switch's internal 30V-rated FET while enabling compact DFN placement. |
| 22V Industrial Power Rail Protection | IoT Device DC Power Input Protection |
Use Scenario: Securing 22V nominal DC power inputs in programmable logic controllers (PLCs), motor drives, and factory automation equipment. IC Role / Device Role / Timing Role: Standalone EOS protector on main supply rail, coordinated with upstream fuse and downstream LDO/regulator. Use Value: Delivers 1120W peak power handling and ±30kV ESD immunity - satisfies IEC 61000-4-5 Level 4 and IEC 61000-4-2 Class 4 requirements without external crowbar circuitry. |
Use Scenario: Hardening 22V input ports of battery-backed IoT gateways, smart sensors, and edge AI modules deployed in uncontrolled environments. IC Role / Device Role / Timing Role: First-line transient suppressor at board edge, preceding DC-DC converter and system MCU. Use Value: 175pF capacitance and 600nA leakage at 22V - minimizes standby power loss and avoids interference with low-power sleep modes in always-on devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Same device - JAN1N5420 is Semtech's military-grade (JAN) variant of TDS2211P, with identical electrical specs, pinout, and DFN package. | No functional difference; qualified to MIL-PRF-19500/560 for enhanced reliability and screening. | Select JAN1N5420 for defense, aerospace, or high-reliability industrial programs requiring MIL-spec traceability and extended temperature validation. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A; higher clamping, no constant-voltage behavior, 1000W PPPK. | Larger SMC package (7.11 × 6.22 mm); unsuitable for space-constrained USB-C or IoT designs. | Choose SMAJ22A only if cost sensitivity outweighs clamping performance and board area constraints - not recommended for 22V systems requiring tight voltage margins. |
Compared with TDS2211P and SMAJ22A, JAN1N5420 provides identical protection performance in a MIL-qualified form factor, whereas SMAJ22A introduces 7–8V higher clamping and requires >4× more PCB area - making JAN1N5420 optimal for high-density, high-reliability 22V surge protection.

FAQ
What is the exact function of JAN1N5420 in a circuit?
JAN1N5420 functions as a transient diverting suppressor that actively shunts high-energy EOS events - such as ESD, lightning surges, or inductive switching spikes - from a 22V power or I/O line to ground. It does so using a precision-triggered FET rather than passive avalanche breakdown, enabling stable 27.5–28V clamping across its full 40A surge rating and operational temperature range. This behavior makes JAN1N5420 distinct from standard TVS diodes and critical for protecting sensitive 22V-rated ICs like USB PD controllers.
How does JAN1N5420 differ from commercial TDS2211P?
JAN1N5420 is the JAN (Joint Army-Navy) qualified version of TDS2211P, sharing identical electrical specifications, pinout, DFN 1.6×1.6mm package, and functional diagram. The distinction lies in manufacturing screening: JAN1N5420 undergoes MIL-PRF-19500/560 testing for enhanced reliability, including extended temperature cycling, hermeticity verification, and lot traceability - making it suitable for defense, aerospace, and mission-critical industrial applications where commercial-grade parts are insufficient.
Can JAN1N5420 be used on high-speed data lines like USB SuperSpeed?
No, JAN1N5420 is not suitable for high-speed data lines such as USB 3.x SuperSpeed (TX/RX), DisplayPort, or HDMI. Its 175pF junction capacitance at 22V is optimized for DC or low-frequency power rail protection, not signal integrity preservation. For those interfaces, Semtech recommends ultra-low-capacitance TVS devices like RClamp3371ZC (<0.25pF). JAN1N5420 is strictly intended for 22V power bus or control-line protection where bandwidth is not a constraint.
What is the recommended PCB layout for JAN1N5420?
Place JAN1N5420 as close as possible to the protected connector or entry point. Connect all three IN pins (4, 5, 6) via a single short, wide trace to the protected line, and tie all three GND pins (1, 2, 3) directly to a solid ground plane using multiple vias. Avoid thermal relief on GND pads. Do not use a thermal pad - energy is dissipated within the silicon FET, not through conduction. This layout minimizes parasitic inductance and ensures full 40A surge capability.
Does JAN1N5420 require external biasing or control signals?
No, JAN1N5420 is a fully autonomous, two-terminal protection device with no external control pins, enable inputs, or bias requirements. It operates passively: when voltage across its IN-to-GND terminals exceeds the trigger threshold (~25V breakdown), the internal circuit activates the shunt FET, clamping the line without any external intervention. This simplifies design, eliminates BOM count, and ensures fail-safe operation even in unpowered or brown-out conditions.
