Product details
Overview
JAN1N5415 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 - deployed in USB PD, USB Type-C, and industrial load switch input protection.
For engineers reviewing the JAN1N5415 datasheet, pinout, applications, or equivalent options, this device delivers stable clamping across temperature (−40°C to +125°C) and current (24–40A), supports compact DFN 1.6×1.6mm layout, and replaces conventional TVS diodes where constant-voltage surge suppression is critical.
Technical Context
The JAN1N5415 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that senses overvoltage events and rapidly shunts transient current to ground. Its clamping voltage remains nearly constant due to the FET's decreasing RDS(on) under surge conditions.
Unlike standard TVS diodes whose clamping rises linearly with peak pulse current (VC = VBR + IPP × RDYN), the JAN1N5415 maintains ~27.6V clamping from 24A to 40A (1.2/50μs + 8/20μs combo wave, RS = 2Ω) and exhibits minimal drift from −40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC bus voltage the device protects without leakage or degradation. |
| Clamping Voltage | 27.6–28V at 40A (1.2/50μs + 8/20μs combo wave) - ensures protected ICs (e.g., 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. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds common system-level ESD test requirements for external ports. |
| Dynamic Resistance | 20mΩ - enables low-voltage drop during conduction, minimizing power dissipation and thermal stress under surge. |
| Junction Capacitance | 175pF at 22V, 1MHz - compatible with medium-speed data/power lines (e.g., USB PD VBUS, load switch inputs), not high-speed differential pairs. |
| Operating Temperature | −40°C to +125°C - supports deployment in industrial, automotive-adjacent, and ruggedized embedded systems. |
Pinout & Package
Package: DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead, RoHS-compliant, UL 94V-0 molding compound, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground terminals - all three must be connected to minimize parasitic inductance and maximize surge current handling. |
| 4, 5, 6 | IN | Protected line input - connects directly to VBUS or power/data line; all three pins are internally tied and must be routed together for full 40A rating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.4V across 24–40A surge range - eliminates design margin uncertainty caused by TVS voltage rise with current. |
| Temperature-stable clamping | Clamps at ~27.6V from −40°C to +125°C - removes derating calculations required for conventional TVS devices. |
| Low dynamic resistance | 20mΩ enables efficient energy diversion with <1.1W instantaneous power dissipation at 40A - reduces thermal stress on PCB and adjacent components. |
| High-energy ESD robustness | ±30kV contact/air per IEC 61000-4-2 - protects exposed connectors without additional staging or filtering. |
| Compact footprint | 1.6×1.6mm DFN saves >60% board area vs. comparable SOT-23 or SOIC TVS solutions - ideal for space-constrained USB Type-C and IoT designs. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |

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 | Identical electrical specs and package - JAN1N5415 is a military-grade variant (JAN prefix) of TDS2211P with extended screening and traceability. | Same use cases; preferred for defense/aerospace programs requiring MIL-PRF-19500 compliance and lot traceability. | Select JAN1N5415 when QPL listing, radiation tolerance, or extended temperature validation per MIL-STD-883 is required. |
| Littelfuse SP3022-01FTG | Standard TVS diode; 24V working voltage, 33.6V clamping at 20A, higher dynamic resistance (~0.5Ω), clamping rises with current/temperature. | Suitable for cost-sensitive consumer applications with lower surge severity; not recommended where constant clamping or high-temp stability is mandatory. | Choose SP3022-01FTG only if design tolerates higher clamping voltage and does not require operation above 85°C. |
Compared with TDS2211P and SP3022-01FTG, JAN1N5415 provides identical performance with enhanced reliability assurance for mission-critical systems, whereas SP3022-01FTG requires significant derating at elevated temperatures and fails to maintain clamping stability across its rated current range.

FAQ
What is the key functional difference between JAN1N5415 and standard TVS diodes?
JAN1N5415 uses a surge-rated FET and precision trigger circuit to achieve near-constant clamping voltage (27.6–28V) across its full 24–40A surge range and −40°C to +125°C operating temperature. Standard TVS diodes exhibit rising clamping (VC = VBR + IPP × RDYN) with both current and temperature, requiring larger safety margins. JAN1N5415 eliminates this uncertainty, making it ideal for protecting sensitive 22V-rated ICs like USB PD controllers.
Does JAN1N5415 require external bias or control signals to operate?
No, JAN1N5415 is fully passive and self-activating. It requires no external power, enable signals, or configuration. The internal trigger circuit monitors voltage across pins 4–6 and pins 1–3; when an overvoltage event exceeds the breakdown threshold, it autonomously activates the shunt FET. This makes JAN1N5415 drop-in compatible with existing TVS placements without modifying control logic or power routing.
Can JAN1N5415 be used on high-speed data lines such as USB SuperSpeed or PCIe?
No, JAN1N5415 is not suitable for high-speed differential data lines. Its 175pF junction capacitance at 22V would severely degrade signal integrity on >1Gbps links. It is specifically designed for power rails (e.g., USB PD VBUS, load switch inputs) and medium-speed single-ended lines. For SuperSpeed lanes, Semtech recommends low-capacitance devices like RClamp3371ZC (<0.25pF), which complement JAN1N5415 in full USB Type-C protection schemes.
What is the significance of the "JAN" prefix in JAN1N5415?
The "JAN" prefix denotes Joint Army-Navy specification compliance, indicating JAN1N5415 is manufactured and tested to MIL-PRF-19500 requirements for reliability, environmental robustness, and traceability. It undergoes extended screening including temperature cycling, hermeticity testing, and lot-level qualification per MIL-STD-883. This distinguishes it from commercial-grade TDS2211P while maintaining identical electrical performance and pinout.
How should JAN1N5415 be laid out on the PCB to ensure optimal surge performance?
Place JAN1N5415 as close as possible to the protected connector. Route pins 4–6 (IN) together via a single short, wide trace to minimize inductance; connect all three GND pins (1–3) directly to a solid ground plane using multiple vias. Avoid stubs or splits in the IN or GND paths. Do not use thermal pads - energy is dissipated in the silicon FET, not the package. Follow Semtech's land pattern (1.6×1.6mm DFN) precisely to ensure solder joint integrity under repeated surge stress.
