Product details
Overview
RCLAMP0504PBTCT from Semtech is a low-capacitance TVS array designed to protect four high-speed data lines (pins 1, 3, 4, 6) and a power line against ESD (±15kV air, ±8kV contact), EFT (40A), and CDE events. It features 1.9pF typical junction capacitance, 5.0V working voltage, and clamps transients to ≤12V at 6A IPP in SLP1616P6 package.
For engineers reviewing the RCLAMP0504PBTCT datasheet, pinout, applications, or equivalent options, key selection criteria include I/O line count (4), ultra-low capacitance (<3pF), IEC 61000-4-2 Level 4 compliance, and SLP1616P6 footprint compatibility with USB 2.0, SD/MMC, and SIM port layouts.
Technical Context
The RCLAMP0504PBTCT integrates four surge-rated steering diodes and one bidirectional TVS diode in a single 6-pin monolithic array. Each I/O pin (1, 3, 4, 6) connects to ground via a steering diode, while pin 5 serves as the positive reference input for supply-rail clamping or floats when using internal TVS as reference.
Its solid-state silicon-avalanche architecture enables sub-nanosecond response to transients, with clamping voltage of 12V at 6A IPP (8/20µs) and insertion loss <−0.32dB up to 1.8GHz - critical for preserving signal integrity in USB 2.0 and MDDI interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 5.0V - defines maximum continuous DC voltage applied to protected lines without leakage activation. |
| Clamping Voltage | 12V at 6A IPP - limits transient voltage seen by downstream ICs during ESD/EFT events. |
| Junction Capacitance | 1.9pF at 0V - ensures minimal signal distortion on high-speed lines up to 2.0GHz. |
| ESD Withstand | ±15kV air / ±8kV contact per IEC 61000-4-2 - meets industrial and portable device immunity requirements. |
| Peak Pulse Power | 150W at 25°C - sustains short-duration surges without degradation in compact SLP1616P6 form factor. |
| Leakage Current | 3µA max at 5V - prevents battery drain in always-on mobile interfaces like SIM and keypads. |
Pinout & Package
The RCLAMP0504PBTCT is housed in a RoHS-compliant SLP1616P6 package measuring 1.6 × 1.6 × 0.60 mm with 0.5 mm pitch and NiPdAu lead finish. Pin 2 is unconnected; pins 1, 3, 4, and 6 serve as protected I/O terminals; pin 5 is the positive reference input; pin 6 is ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 6 | I/O Protection Terminal | Each connects to one high-speed data line (e.g., USB D+, D−, SD CLK, CMD); steers ESD current to GND. |
| 2 | No Connect | Internally unconnected - must remain floating per datasheet; no PCB trace required. |
| 5 | Positive Reference Input | Connects to VCC to clamp data lines to supply rail; left open to use internal TVS as reference. |
| 6 (GND) | Ground Reference | Low-inductance connection point to system ground plane - shortest possible trace required. |
Key Features
| Feature | Design Value |
|---|---|
| Four-line protection in single package | Reduces board area vs. discrete TVS solutions - saves >70% space over four 0201 devices. |
| 1.9pF typical capacitance | Preserves signal rise/fall times in USB 2.0 (480Mbps) and SD card (25MHz) interfaces. |
| 12V clamping at 6A IPP | Ensures protected ICs (e.g., USB transceivers) stay within safe operating voltage margins. |
| SLP1616P6 footprint | Enables automated placement and reflow compatibility with standard 0606-size land patterns. |
| UL 94V-0 molding compound | Meets flammability safety standards for consumer electronics enclosures and handheld devices. |
Applications
| USB 2.0 Interface Protection | SD/MMC Card Slot Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines in smartphone USB OTG receptacles from repeated plug/unplug ESD events. IC Role / Device Role / Timing Role: Transient voltage suppressor placed between connector and USB PHY IC. Use Value: Maintains <−0.32dB insertion loss at 1.8GHz while clamping 8kV contact ESD to ≤12V - preventing PHY latch-up or damage. | Use Scenario: Shielding SDIO command, clock, and data lines in portable media players from cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance array connected directly at SD card edge connector. Use Value: 1.9pF capacitance avoids timing skew on 25MHz SD clock; 15kV air ESD rating exceeds IEC 61000-4-2 Level 4. |
| SIM Card Port Protection | Gigabit Ethernet PHY Protection |
Use Scenario: Safeguarding SIM VCC, I/O, RST, and CLK pins in LTE modules exposed to user-handling ESD. IC Role / Device Role / Timing Role: Four-channel TVS array tied to SIM slot with pin 5 connected to 3.3V rail. Use Value: Simultaneous protection of all four SIM signals with <3pF loading - prevents communication errors during hot-swap events. | Use Scenario: Adding secondary ESD robustness to 1000BASE-T PHY differential pairs in industrial gateways. IC Role / Device Role / Timing Role: Steering diode array placed before magnetics to shunt common-mode transients. Use Value: 40A EFT (5/50ns) capability handles burst noise on PoE-powered Ethernet ports without degrading 1.25Gbps signal integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-04UTG | Higher capacitance (3.5pF), lower clamping voltage (9.5V at 6A), same SLP1616P6 package. | Better for 3.3V systems needing tighter clamping; less suitable for 5V USB 2.0 due to higher capacitance-induced jitter. | Select SP1006-04UTG when clamping voltage margin is prioritized over GHz-range signal fidelity. |
| TPD4E001DPYR | Lower working voltage (3.3V), identical 1.9pF capacitance, same 6-pin X2SON package but different pinout (GND on pin 1). | Requires PCB layout change; optimized for 3.3V I/O like eMMC, not 5V USB or SD card rails. | Choose TPD4E001DPYR only if redesigning for 3.3V-only interfaces and verifying pin mapping compatibility. |
Compared with SP1006-04UTG and TPD4E001DPYR, the RCLAMP0504PBTCT uniquely balances 5.0V operation, 1.9pF capacitance, and IEC 61000-4-2 Level 4 compliance - making it optimal for legacy 5V high-speed interfaces where signal integrity and voltage margin are co-constrained.

FAQ
What is the exact pin configuration and function of each terminal on the RCLAMP0504PBTCT?
The RCLAMP0504PBTCT uses a 6-pin SLP1616P6 package: pins 1, 3, 4, and 6 are I/O protection terminals for data lines; pin 2 is unconnected (NC); pin 5 is the positive reference input (connect to VCC or leave open); pin 6 is ground. This configuration is confirmed in Semtech's official datasheet revision 10/26/2007, Figure 1 "Pin Configuration (Top Side View)".
Does the RCLAMP0504PBTCT support both unidirectional and bidirectional transient suppression?
Yes, the RCLAMP0504PBTCT provides bidirectional ESD protection per I/O line. Its internal architecture combines steering diodes and a bidirectional TVS diode, enabling clamping of both positive and negative transients - validated by ±15kV air and ±8kV contact ESD test results per IEC 61000-4-2.
Can the RCLAMP0504PBTCT be used to protect a 5V USB 2.0 interface without signal degradation?
Yes, the RCLAMP0504PBTCT is explicitly qualified for USB 2.0: its 1.9pF typical capacitance and <−0.32dB insertion loss at 1.8GHz preserve signal integrity, while 5.0V working voltage matches USB VBUS tolerance. Application diagrams in the datasheet confirm direct placement on D+/D− lines upstream of the PHY.
What is the thermal derating behavior of the RCLAMP0504PBTCT above 25°C ambient?
The RCLAMP0504PBTCT exhibits linear power derating above 25°C: at 75°C ambient, it delivers 70% of rated 150W peak pulse power; at 125°C, it retains 30%. This curve is documented in the "Power Derating Curve" figure (page 3) of the official datasheet.
Is the RCLAMP0504PBTCT compliant with RoHS and REACH regulations?
Yes, the RCLAMP0504PBTCT is RoHS/WEEE compliant, with lead-free NiPdAu terminal finish and UL 94V-0 molding compound. Compliance is stated in the "Mechanical Characteristics" section and confirmed in the "Ordering Information" table (page 9) of the Semtech datasheet.
