Product details
Overview
1N6153US 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), and stable 27.5–28V clamping across temperature and current range - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the 1N6153US datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, DFN-6 package layout guidance, real-world clamping behavior vs. conventional TVS, and validated alternatives for 22V bus protection in high-reliability embedded and power delivery systems.
Technical Context
The 1N6153US employs 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 standard TVS diodes, its clamping voltage remains nearly constant (27.5–28V) from 24A to 40A IPP due to decreasing RDS(on), not fixed dynamic resistance.
It operates over –40°C to +125°C with <600nA reverse leakage at 22V, 175pF junction capacitance at 22V/1MHz, and 20mΩ dynamic resistance (8/20μs), enabling robust protection without thermal derating penalties typical of junction-based TVS devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 22 V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or conduction. |
| Clamping Voltage (VC) | 27.5–28 V at 40A (8/20μs + 1.2/50μs combo wave, RS=2Ω) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current (IPP) | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds Level 4 immunity for handheld and connector-exposed interfaces. |
| Junction Capacitance (CJ) | 175 pF at 22V, 1MHz - low enough for 22V power rail protection without signal integrity impact on adjacent traces. |
| Dynamic Resistance (RDYN) | 20 mΩ (8/20μs) - enables flat clamping response and minimal voltage rise under increasing surge current. |
Pinout & Package
1N6153US is housed in a Pb-free, RoHS-compliant DFN-6 package measuring 1.6 mm × 1.6 mm × 0.55 mm with exposed thermal pad (no solder mask defined). All six terminals are surface-mount; pins 1–3 are internally connected GND, pins 4–6 are internally connected IN - requiring full connection of each group for rated 40A surge performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return path for surge current; all three must be soldered to solid ground plane with multiple vias to minimize inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS in USB PD); all three pins connect in parallel to same trace - no internal differentiation. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables near-constant clamping voltage (27.5–28V) across full 24–40A surge range - eliminates linear VC = VBR + IPP×RDYN drift seen in TVS diodes. |
| Temperature-stable clamping | Clamping remains ≤28V from –40°C to +125°C - avoids thermal derating and enables reliable protection in uncontrolled ambient environments. |
| Low dynamic resistance | 20 mΩ measured between 1A–40A (8/20μs) - minimizes IR drop and power dissipation during high-current transients. |
| High EFT immunity | ±4 kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz bursts) - protects against repetitive fast transients common in industrial motor drives and PLCs. |
Applications
| USB Type-C Power Delivery Input Protection | Industrial Load Switch Front-End Protection |
|---|---|
Use Scenario: Protecting VBUS lines in USB-C receptacles supporting up to 20V/5A PD negotiation, exposed to ESD from hot-plug events and lightning-induced surges on long cables. IC Role / Device Role / Timing Role: Primary EOS shunt device placed immediately after connector, clamping transients before they reach USB PD controller or load switch IC. Use Value: Maintains 27.5–28V clamping at 40A and 125°C - prevents overvoltage damage to 24V-rated PD controllers where conventional TVS would exceed 35V at elevated temperature. |
Use Scenario: Safeguarding input terminals of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and factory automation equipment subject to 1kV/42Ω surges. IC Role / Device Role / Timing Role: Front-line transient diverter that routes surge energy to ground before it stresses the load switch's internal MOSFET gate oxide or drain-source junction. Use Value: Limits clamping to ≤28V across full temperature and current range - keeps stress below 80% of typical 35V load switch absolute max ratings, extending field reliability. |
| IoT Device Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary power rails in battery-backed IoT edge nodes deployed outdoors or in electrically noisy environments (e.g., smart grid sensors). IC Role / Device Role / Timing Role: Standalone EOS protector for non-isolated DC input, replacing multi-device TVS+filter solutions with single-component footprint. Use Value: 1.6×1.6mm DFN-6 saves >60% board area versus discrete TVS + series impedance solutions while delivering superior clamping consistency. |
Use Scenario: Protecting 22V backup supply inputs in NVMe SSDs or enterprise HDDs where transient exposure occurs during hot-swap or power sequencing faults. IC Role / Device Role / Timing Role: Low-capacitance (175pF), low-leakage (≤600nA) shunt clamp ensuring no standby current penalty or signal coupling into high-speed data lanes. Use Value: Enables direct placement at connector without degrading PCIe Gen4/Gen5 signal integrity - unlike higher-capacitance TVS arrays requiring separation or filtering. |
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 die, identical electrical specs and package - direct Semtech-marked variant of 1N6153US; pinout, clamping, and thermal behavior fully matched. | No functional difference; used interchangeably in USB-C and industrial designs per Semtech documentation. | Select TDS2211P when sourcing directly from Semtech distribution channels or requiring official Semtech part marking. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A (8/20μs), 1.5W PPPK; lacks FET-based flat clamping and temperature stability. | Higher clamping voltage increases risk of downstream IC damage at 40A or >85°C; suitable only for lower-energy, cost-sensitive applications. | Choose SMAJ22A only if surge threat is limited to <15A and ambient stays <70°C - not recommended for USB PD or industrial 40A compliance. |
Compared with TDS2211P and SMAJ22A, the 1N6153US delivers identical protection performance to TDS2211P but with alternate packaging/marking, while offering significantly flatter clamping and wider temperature margin than SMAJ22A - making it the preferred choice for mission-critical 22V bus protection where reliability trumps lowest BOM cost.

FAQ
What is the exact clamping voltage specification for 1N6153US at 40A surge current?
The 1N6153US clamps at 27.6–28 V under IEC 61000-4-5 combination waveform conditions (1.2/50μs voltage + 8/20μs current, RS = 2Ω) at 40A peak pulse current - confirmed in Semtech's TDS2211P datasheet Rev 2.5, page 2, Electrical Characteristics table. This value holds across –40°C to +125°C operating temperature.
Is 1N6153US pin-compatible with TDS2211P?
Yes - the 1N6153US and TDS2211P share identical DFN-6 package dimensions, pin configuration (pins 1–3 = GND, pins 4–6 = IN), thermal pad layout, and electrical specifications. Semtech documents both as functionally equivalent variants; no PCB layout changes are required when substituting 1N6153US for TDS2211P.
Does 1N6153US require a thermal pad or heatsink on the PCB?
No - the 1N6153US dissipates surge energy via its internal FET shunt path, not junction heating. Semtech explicitly states "no thermal pad is needed" (TDS2211P datasheet, page 6). Instead, robust grounding of all three GND pins (1–3) with multiple vias to an internal ground plane is critical for achieving rated 40A performance.
Can 1N6153US protect bidirectional data lines like USB DP/DM?
No - the 1N6153US is designed exclusively for unidirectional 22V power or I/O line protection (e.g., VBUS, load switch input). Its 175pF capacitance and lack of symmetrical breakdown make it unsuitable for high-speed data lines. For DP/DM, Semtech recommends low-capacitance TVS like RClamp3371ZC (<0.25pF), as specified in the TDS2211P application note (page 5).
What is the maximum operating temperature range for 1N6153US?
The 1N6153US is rated for continuous operation from –40°C to +125°C ambient temperature, with junction temperature reaching up to +150°C under surge conditions. Its clamping voltage remains stable within 27.5–28V across this full range - a key differentiator from standard TVS diodes whose clamping rises significantly above 85°C.
