Product details
Overview
JAN1N6461US.TR from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-rated I/O or power lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and ultra-low 20mΩ dynamic resistance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the JAN1N6461US.TR datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, real-world clamping stability across temperature and current, and direct alternative options for 22V bus protection design.
Technical Context
The JAN1N6461US.TR 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 - 27.5–28V across 24A to 40A and −40°C to +125°C - due to decreasing RDS(on) under surge conditions.
It operates with reverse stand-off voltage (VRWM) of 22V, breakdown voltage (VBR) of 25–27.9V at 1mA, and exhibits only 130–600nA leakage at VRWM. Its 175pF junction capacitance at 22V/1MHz and 1120W peak pulse power rating support robust protection without signal integrity compromise in high-speed interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC operating voltage of protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo waveform) - ensures downstream ICs like USB PD controllers remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air per IEC 61000-4-2 - exceeds automotive and industrial ESD immunity standards without derating. |
| Dynamic Resistance | 20mΩ - enables flat clamping response and minimizes voltage overshoot during fast-rising transients. |
| Junction Capacitance | 175pF at 22V/1MHz - low enough for USB Type-C VBUS protection without degrading power delivery signaling integrity. |
Pinout & Package
Package: DFN-6 (1.6mm × 1.6mm × 0.55mm), Pb-free, RoHS/WEEE compliant, UL 94V-0 molding compound, tape-and-reel packaging.
| 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 parasitic inductance. |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBUS); parallel connection ensures uniform current sharing and full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies <0.5V across 24–40A and −40°C to +125°C - eliminates thermal runaway risk and simplifies worst-case margining. |
| FET-based shunt topology | Replaces traditional pn-junction TVS with active switching; dissipates energy in channel rather than junction, enabling higher IPP at smaller die size. |
| Low dynamic resistance | 20mΩ measured between 1A–40A (8/20μs) - reduces IR drop during surge, maintaining tighter voltage control than TVS diodes (typically >100mΩ). |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz bursts) - protects against repetitive fast transients common in motor drives and PLC environments. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS lines in USB Type-C ports supporting up to 20V/5A PD profiles against lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Transient diverting suppressor placed directly at connector, clamping overvoltage before it reaches PD controller or load switch. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - avoids false OVP trips and ensures PD negotiation integrity under harsh ambient conditions. |
Use Scenario: Front-end protection of high-side load switches (e.g., HS2950P) in remote meters, robotics, and IoT gateways exposed to 1kV/42Ω surges. IC Role / Device Role / Timing Role: Primary surge shunt device limiting voltage stress on internal FET drain-source junction during EOS events. Use Value: Prevents latch-up or permanent damage to load switch by holding clamping <28V - well below typical 30V+ VDSS ratings while sustaining 40A pulses. |
| Storage Device Power Bus Protection | Notebook/Tablet VBUS Line Protection |
Use Scenario: Safeguarding 22V-capable NVMe SSD power rails and eMMC VCCQ inputs against system-level ESD coupling and board-level surges. IC Role / Device Role / Timing Role: Low-capacitance (175pF), high-power transient suppressor placed adjacent to connector or PMIC input. Use Value: Enables compact 1.6×1.6mm footprint without sacrificing surge rating - critical for space-constrained M.2 and U.2 form factors. |
Use Scenario: Securing main VBUS input in ultrabooks and tablets where thermal headroom is limited and ambient temperatures exceed 85°C. IC Role / Device Role / Timing Role: Temperature-stable clamping device ensuring consistent protection margin across full operating range. Use Value: Delivers identical 27.5–28V clamping at −40°C, 25°C, and 125°C - eliminates need for derating or dual-device redundancy. |
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.C | Same silicon, identical electrical specs, but marked "T22" and shipped in 7″ reel (3,000 pcs); JAN1N6461US.TR is military-grade screened variant with US-part-numbering convention. | Commercial-grade version lacks MIL-PRF-19500 screening; suitable for non-military industrial or consumer designs requiring same performance at lower cost. | Select TDS2211P.C for commercial volume production where extended temperature qualification and radiation tolerance are not required. |
| Littelfuse SP3022-01WTG | TVS diode (not FET-based); 22V VRWM, 33.6V clamping at 12A (8/20μs), 120mΩ RDYN - clamping rises significantly with current and temperature. | Lower peak current rating (12A vs. 40A); requires larger layout area and cannot maintain stable clamping above 25°C without derating. | Choose SP3022-01WTG only if cost sensitivity outweighs clamping stability and surge margin - not recommended for USB PD or industrial 40A surge compliance. |
Compared with JAN1N6461US.TR, TDS2211P.C offers identical protection performance in commercial grade, while SP3022-01WTG provides lower-cost TVS-based protection but sacrifices clamping consistency, temperature stability, and surge current headroom - making JAN1N6461US.TR the optimal choice for mission-critical 22V bus protection.

FAQ
What is the exact clamping voltage specification for JAN1N6461US.TR at 40A?
The JAN1N6461US.TR has a guaranteed clamping voltage of 27.5–28V at 40A using the IEC 61000-4-5 combination waveform (1.2/50μs voltage + 8/20μs current, RS = 2Ω). This value is confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables of the official Semtech datasheet Rev 2.5, and remains stable across −40°C to +125°C.
Is JAN1N6461US.TR pin-compatible with standard DFN-6 packages?
Yes, JAN1N6461US.TR uses the industry-standard 1.6mm × 1.6mm × 0.55mm DFN-6 package with 0.5mm pitch. Pin 1 is marked by a laser dot; pins 1–3 are GND, pins 4–6 are IN. The land pattern matches Semtech's recommended layout in the datasheet - no PCB redesign is needed when migrating from TDS2211P.C or other compatible DFN-6 suppressors.
Does JAN1N6461US.TR require external bias or control signals to operate?
No, JAN1N6461US.TR is fully autonomous - it contains an integrated precision trigger circuit and surge-rated FET. It requires only two connections: the protected line (pins 4–6) and ground (pins 1–3). No enable pin, voltage reference, or external timing components are needed, simplifying layout and reducing BOM count.
How does JAN1N6461US.TR compare to traditional TVS diodes in temperature performance?
JAN1N6461US.TR maintains a near-constant 27.5–28V clamping voltage from −40°C to +125°C, whereas conventional TVS diodes exhibit rising clamping (e.g., +5–10V increase at 125°C) due to fixed dynamic resistance. This stability eliminates thermal derating and ensures reliable protection in high-ambient environments like enclosed industrial enclosures or automotive under-hood zones.
Can JAN1N6461US.TR be used for bidirectional signal line protection?
No - JAN1N6461US.TR is unidirectional and designed exclusively for DC power rail or single-ended I/O protection (e.g., VBUS, load switch input). Its pin configuration (GND/IN only) and electrical characteristics (22V VRWM, forward conduction path) do not support AC or bidirectional data line protection such as USB SS, DP/DM, or CAN. Use RClamp3371ZC or uClamp2411ZA for those applications.
