Product details
Overview
TCLAMP0602N.TCT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS/ESD protection of 22V-rated power or I/O 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, industrial load switch inputs, and IoT device bus protection.
For engineers reviewing the TCLAMP0602N.TCT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability under surge, low dynamic resistance (<20 mΩ), junction capacitance (175 pF @ 22V), DFN 1.6×1.6mm package constraints, and compatibility with 22V working voltage systems requiring robust EOS resilience.
Technical Context
The TCLAMP0602N.TCT uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant due to decreasing RDS(on) under increasing surge current.
It operates over –40°C to +125°C, maintains ≤600 nA reverse leakage at 22V, and delivers 1120W peak pulse power (8/20μs). Its functional architecture separates input (pins 4–6) and ground (pins 1–3) terminals to minimize parasitic inductance during high-dI/dt events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22 V - matches nominal USB PD bus and industrial 24V rail derating requirements. |
| Clamping Voltage | 27.5–28 V at 40A (8/20μs) - ensures protected ICs (e.g., USB PD controllers) remain below damage thresholds. |
| Peak Pulse Current | 40 A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment. |
| ESD Withstand | ±30 kV contact & air (IEC 61000-4-2) - exceeds automotive and consumer interface ESD requirements. |
| Dynamic Resistance | 20 mΩ - enables low-voltage overshoot during fast transients, critical for sensitive downstream logic. |
| Junction Capacitance | 175 pF @ 22V, 1 MHz - suitable for DC/low-speed power line protection; not intended for high-speed data lines. |
| Package | DFN 1.6 mm × 1.6 mm × 0.55 mm, 6-lead - enables compact placement near connectors with minimal PCB area. |
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 return path for surge current; all three must be connected to maximize current handling and minimize inductance. |
| Pins 4, 5, 6 | IN | Protected line input (e.g., VBUS or power rail); parallel connection ensures uniform current sharing and optimal clamping performance. |
Key Features
| Feature | Design Value |
|---|---|
| Constant clamping voltage | Stable 27.5–28 V across 24–40A surge range and –40°C to +125°C - eliminates thermal derating uncertainty in industrial environments. |
| FET-based shunt architecture | Surge-rated MOSFET with sub-0.1 Ω RDS(on) replaces PN-junction TVS - reduces voltage overshoot and improves energy dissipation efficiency. |
| Low dynamic resistance | 20 mΩ measured between 1A–40A (8/20μs) - minimizes IR drop during surge, preserving margin for downstream overvoltage tolerance. |
| High EFT immunity | ±4 kV per IEC 61000-4-4 (5/50 ns, 100 kHz/5 kHz) - protects against repetitive burst noise in motor drives and PLC I/O modules. |
Applications
| USB Type-C Power Delivery Bus Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS lines in USB-C receptacles supporting up to 20V/5A PD negotiation, exposed to ESD and lightning-induced surges. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed directly at connector, clamping transients before reaching PD controller and load switch. Use Value: Maintains 27.5–28 V clamping across temperature - avoids overvoltage damage to 24V-tolerant PD controllers even at 125°C ambient. |
Use Scenario: Safeguarding enable and input pins of industrial-grade load switches (e.g., HS2950P) in remote meters, robotics, and factory automation. IC Role / Device Role / Timing Role: Front-end transient diverter that limits voltage stress on internal FET gate oxide and drain-source junction during surge events. Use Value: Prevents latch-up or permanent failure of load switches rated for ≤30V absolute maximum, extending field reliability in harsh EMC environments. |
| IoT Device Power Rail Protection | Storage Device 22V Backup Supply Protection |
Use Scenario: Securing 22V auxiliary rails in battery-backed smart sensors and edge gateways subjected to ESD during field servicing or cable hot-plug. IC Role / Device Role / Timing Role: Low-leakage (≤600 nA @ 22V), high-impedance standby protector that activates only during transients >25V. Use Value: Enables always-on operation without measurable quiescent power penalty while delivering 40A surge capacity for system-level IEC 61000-4-5 compliance. |
Use Scenario: Shielding 22V supercapacitor or LiFePO₄ backup supplies in enterprise SSDs and NAS enclosures from AC-line coupled surges. IC Role / Device Role / Timing Role: Fast-response (sub-ns trigger latency) clamp that diverts energy away from backup regulator ICs and storage capacitors. Use Value: Preserves data integrity during brownout+surge events by preventing overvoltage-induced capacitor venting or regulator shutdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | Standard unidirectional TVS diode; clamping rises linearly with current (VC ≈ VBR + IPP × RDYN); 38V clamping at 24A/125°C vs. TCLAMP0602N.TCT's stable 28V. | Limited to lower-temperature or lower-surge applications where clamping drift is acceptable; lacks FET-based thermal stability. | Select SMAJ22A only if cost sensitivity outweighs clamping consistency and temperature margin requirements. |
| TPD2E001DRYR | Low-capacitance (1.5 pF) dual-channel ESD protector; rated for 5.5V max working voltage and ±8kV ESD - not suitable for 22V EOS or 40A surge. | Designed for high-speed data lines (USB 2.0, HDMI), not power rails; insufficient voltage rating and surge capability for TCLAMP0602N.TCT use cases. | Use TPD2E001DRYR only for signal-line ESD co-protection alongside TCLAMP0602N.TCT - never as a replacement. |
Compared with SMAJ22A and TPD2E001DRYR, TCLAMP0602N.TCT uniquely delivers stable 28V clamping across full temperature and current range using FET-shunt architecture - making it the sole option among the three qualified for 22V industrial power rail EOS protection meeting IEC 61000-4-5 Level 4.

FAQ
What is the maximum operating temperature for TCLAMP0602N.TCT?
TCLAMP0602N.TCT is rated for continuous operation from –40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range, with no degradation in 40A surge capability or 27.5–28V clamping performance - verified per IEC 61000-4-5 testing at extreme temperatures.
Does TCLAMP0602N.TCT require external bias or control signals?
No, TCLAMP0602N.TCT is fully passive and self-triggering. It requires no external power, enable signal, or configuration. The internal precision trigger circuit activates the shunt FET automatically when transient voltage exceeds ~25V, making TCLAMP0602N.TCT ideal for simple, robust front-end protection without added system complexity.
Can TCLAMP0602N.TCT be used on high-speed data lines like USB 3.2 or PCIe?
No, TCLAMP0602N.TCT is not suitable for high-speed data lines. Its 175 pF junction capacitance would severely degrade signal integrity on differential pairs. TCLAMP0602N.TCT is specifically designed for DC or low-frequency power/bus lines (e.g., USB-C VBUS, load switch inputs), not signal paths - use low-capacitance ESD arrays like RClamp3371ZC for those applications.
What is the meaning of "TCLAMP" in the part number TCLAMP0602N.TCT?
"TCLAMP" denotes Semtech's Transient CLAMP product family - a series of FET-based transient diverting suppressors distinguished by constant clamping voltage behavior. The "0602" indicates the DFN 1.6×1.6mm (06×02 inch) package, and "N.TCT" specifies tape-and-reel packaging with standard Semtech marking and RoHS compliance.
How does TCLAMP0602N.TCT compare to traditional TVS diodes in surge response time?
TCLAMP0602N.TCT achieves sub-nanosecond trigger latency due to its active FET-shunt architecture, significantly faster than the avalanche breakdown delay of standard TVS diodes. This rapid response prevents voltage overshoot spikes before clamping engages - a key advantage confirmed in oscilloscope waveforms within the official TCLAMP0602N.TCT datasheet.
