Product details
Overview
JANTX1N5615 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 PD, USB Type-C, and industrial load switch input protection.
For engineers reviewing the JANTX1N5615 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 22V bus protection in high-reliability embedded and industrial systems.
Technical Context
The JANTX1N5615 implements 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 over −40°C to +125°C with stable 27.5–28V clamping up to 40A, 22V reverse stand-off, 25–27.9V breakdown at 1mA, and <600nA leakage at VRWM - all enabled by solid-state architecture and low-inductance 6-pin DFN packaging optimized for minimal PCB parasitics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-Off Voltage | 22 V - maximum continuous operating voltage before clamping activation; defines safe DC/AC bus rating. |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs) - limits transient overvoltage seen by downstream ICs like USB PD controllers. |
| Peak Pulse Current | 40 A (8/20μs) - withstands high-energy surges per IEC 61000-4-5, enabling compliance with industrial surge standards. |
| Dynamic Resistance | 20 mΩ - ensures minimal voltage rise under increasing surge current, enabling flat clamping profile. |
| Junction Capacitance | 175 pF at 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - protects against human-body-model and system-level ESD events. |
| Operating Temperature | −40°C to +125°C - supports deployment in automotive-grade and industrial environments without derating. |
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 |
|---|---|---|
| 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, load switch input); parallel connection ensures uniform current sharing and thermal distribution. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5 V across full 24–40A surge range - eliminates need for over-spec'ed IPP margin to meet voltage thresholds. |
| Temperature-stable protection | Clamping remains 27.5–28 V from −40°C to +125°C - enables reliable design without thermal derating calculations. |
| Low dynamic resistance | 20 mΩ measured between 1A–40A - reduces power dissipation (I²R) and localized heating during multi-pulse events. |
| High-energy ESD robustness | ±30 kV contact & air per IEC 61000-4-2 - exceeds Level 4 requirements, reducing need for secondary board-level shielding. |
| Space-efficient packaging | 1.6 mm × 1.6 mm footprint - saves >60% board area vs. SO-8 or SOT-23 TVS solutions rated for comparable surge energy. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting 20–22V USB PD power bus against lightning-induced surges and connector hot-plug transients. IC Role / Device Role / Timing Role: Transient diverting suppressor placed at Type-C receptacle VBus entry point, upstream of PD controller and e-fuse. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents damage to PD controllers rated for ≤30V absolute max, unlike TVS diodes whose clamping rises with temperature and current. |
Use Scenario: Safeguarding input of industrial-grade load switches (e.g., HS2950P) against EOS in remote meters, robotics, and IoT gateways. IC Role / Device Role / Timing Role: Primary front-end surge clamp on VIN rail, absorbing energy before it reaches internal FET gate oxide or overvoltage protection circuitry. Use Value: Limits transient voltage to ≤28V during ±1kV/42Ω surges - keeps load switch drain-source voltage below breakdown threshold and avoids false OVP triggering. |
| Notebook/Industrial Tablet VBus Protection | IoT Edge Device Power Rail Protection |
Use Scenario: Securing main 22V input rail in ruggedized tablets and portable industrial computers exposed to field ESD and conducted surges. IC Role / Device Role / Timing Role: Solid-state EOS protector replacing traditional TVS arrays, integrated directly at board edge connector. Use Value: Delivers 40A surge handling in 1.6×1.6mm footprint - enables compact, fanless designs while meeting IEC 61000-4-5 Level 3 (±1kV) without external filtering. |
Use Scenario: Protecting 22V auxiliary power inputs in battery-backed smart sensors and wireless gateways deployed in uncontrolled environments. IC Role / Device Role / Timing Role: First-line defense against induced transients from nearby motors, relays, or RF sources coupled onto long supply traces. Use Value: 175pF capacitance and <600nA leakage at 22V - avoids loading sensitive analog or low-power sleep circuits while maintaining fast response (<1ns). |
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 | Identical electrical specs, same DFN-6 package, commercial-grade (−40°C to +85°C) vs. JANTX1N5615's extended −40°C to +125°C rating. | Approved for non-military industrial use; lacks MIL-PRF-19500 qualification and JANTX screening. | Select JANTX1N5615 for aerospace, defense, or extended-temperature industrial deployments requiring military-grade reliability screening. |
| Littelfuse SP3022-01ETG | 22V stand-off, 30A (8/20μs), 33V clamping at 30A, SOD-323 package - higher clamping, lower surge rating, smaller footprint but no temperature stability data above 85°C. | Targeted at consumer USB ports; not validated for sustained 125°C operation or 40A surge compliance. | Choose only for cost-sensitive, space-constrained consumer designs where 33V clamping and 30A rating are acceptable. |
Compared with JANTX1N5615, TDS2211P.C offers identical protection performance with relaxed temperature and screening specs, while SP3022-01ETG trades clamping voltage margin and thermal robustness for smaller size - making JANTX1N5615 the sole option for high-reliability 22V bus protection demanding 40A/125°C capability.

FAQ
What is the clamping voltage of JANTX1N5615 at 40A surge current?
JANTX1N5615 clamps at 27.5–28 V under 40A peak pulse current (8/20μs waveform), with minimal variation across −40°C to +125°C. This flat clamping behavior results from its FET-based architecture and 20mΩ dynamic resistance - ensuring downstream 22V-rated ICs remain within safe operating voltage limits even under worst-case surge and thermal conditions. The JANTX1N5615 datasheet confirms this value is guaranteed by design.
Does JANTX1N5615 require external components for basic operation?
No, JANTX1N5615 operates as a standalone transient suppressor with no external bias, timing, or control components required. Its internal trigger circuit and shunt FET activate autonomously during overvoltage events. Layout best practices - such as connecting all GND pins (1–3) and all IN pins (4–6) with low-inductance traces and placing the JANTX1N5615 within 5 mm of the protected connector - are sufficient for full 40A surge performance.
How does JANTX1N5615 differ from standard TVS diodes in clamping behavior?
Unlike standard TVS diodes whose clamping voltage rises linearly with surge current (VC = VBR + IPP × RDYN), JANTX1N5615 maintains near-constant clamping (27.5–28 V) from 24A to 40A due to its active FET shunt mechanism. Its dynamic resistance drops under surge, counteracting voltage rise - a key advantage confirmed in JANTX1N5615's typical characteristics curves and critical for protecting voltage-sensitive PD controllers.
Is JANTX1N5615 compatible with automated SMT assembly processes?
Yes, JANTX1N5615 uses a standard 6-pin DFN package (1.6 mm × 1.6 mm) with lead-free, RoHS-compliant terminations and UL 94V-0 molding compound - fully compatible with reflow soldering per IPC/JEDEC J-STD-020. Its thermal pad-free design eliminates stencil aperture complications, and the JANTX1N5615 land pattern matches industry-standard DFN-6 footprints for seamless integration into high-volume manufacturing.
What is the maximum operating temperature range for JANTX1N5615?
JANTX1N5615 is rated for continuous operation from −40°C to +125°C, with all key parameters - including clamping voltage, leakage current, and surge capability - specified and validated across this full range. This extended temperature performance distinguishes JANTX1N5615 from commercial variants like TDS2211P.C and makes it suitable for under-hood automotive, industrial control, and aerospace applications where ambient temperatures exceed 85°C.
