Product details
Overview
UCLAMP5612T.TNT from Semtech is a 5-pin ultra-small ESD protection diode array designed for battery interface protection in mobile handsets. It integrates one 12 V TVS (VBatt pin) and two 5 V TVS diodes (Batt_ID and Batt_Therm pins), with ±30 kV IEC 61000-4-2 contact/air ESD rating, 0.15 Ω dynamic resistance on 5 V lines, and 0.25 Ω on the 12 V line - enabling robust board-level ESD immunity for lithium-ion battery monitoring circuits.
For engineers reviewing the UCLAMP5612T.TNT datasheet, pinout, applications, or equivalent options, key selection criteria include dual-voltage clamping capability (5 V / 12 V), SLP1508N5T package compatibility, low junction capacitance (11.5 pF @ 0 V on 5 V lines), and verified ESD performance per IEC 61000-4-2 up to ±30 kV.
Technical Context
The UCLAMP5612T.TNT implements silicon-avalanche TVS technology in a monolithic flow-through layout, with three independent protection channels sharing a common ground (Pin 5). Pin 2 is NC, eliminating routing conflicts. Its architecture supports simultaneous protection of battery voltage bus (VBatt), thermistor (Batt_Therm), and identification (Batt_ID) lines without cross-talk.
Each channel features optimized breakdown voltage (11.5 V min for VBatt; 5.6 V min for Batt_ID/Batt_Therm), low clamping voltage (≤30 V at 10 A for VBatt; ≤12.5 V at 10 A for 5 V lines), and sub-12 pF junction capacitance - preserving signal integrity on analog sensor paths while meeting stringent cellular handset ESD requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating | ±30 kV contact & air per IEC 61000-4-2 - exceeds Level 4 immunity for handheld consumer electronics. |
| Clamping Voltage (VBatt) | ≤30 V at 10 A IPP - limits transient overvoltage seen by PMIC battery input during ESD events. |
| Clamping Voltage (Batt_ID/Batt_Therm) | ≤12.5 V at 10 A IPP - protects ADC inputs and microcontroller GPIOs connected to battery sensors. |
| Junction Capacitance | 11.5 pF (5 V lines), 7.5 pF (VBatt) at 0 V - minimizes signal distortion on thermistor/ID analog sensing paths. |
| Dynamic Resistance | 0.15 Ω (5 V lines), 0.25 Ω (VBatt) - reduces clamping voltage overshoot under fast ESD transients. |
| Operating Voltage | 12 V (VBatt), 5 V (Batt_ID/Batt_Therm) - matches standard Li-ion battery interface voltage domains. |
| Package | SLP1508N5T (1.5 × 0.8 × 0.4 mm) - enables placement directly at battery connector for shortest possible protection path. |
Pinout & Package
The UCLAMP5612T.TNT is housed in a 5-pin SLP1508N5T leadless package measuring 1.5 × 0.8 × 0.40 mm, with 0.35 mm pitch and NiPdAu lead finish. The top-view pin 1 indicator aligns with sprocket holes in tape-and-reel packaging.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VBatt) | 12 V supply line TVS anode | Connects to battery voltage rail; clamps transients above 11.5 V to protect PMIC input stage. |
| 2 (NC) | No internal connection | Unbonded pad; must be left floating or tied to ground only if required for mechanical stability. |
| 3 (Batt_Therm) | 5 V thermistor line TVS anode | Protects NTC thermistor analog return path; low Cj preserves temperature measurement accuracy. |
| 4 (Batt_ID) | 5 V battery ID line TVS anode | Shunts ESD on resistor-divider ID line; prevents false battery detection or MCU reset. |
| 5 (GND) | Common cathode ground | Shared ground reference for all three TVS elements; requires multiple microvias to minimize inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual operating voltage protection | Single device protects both 12 V battery bus and two 5 V analog sensor lines - eliminates need for discrete TVS arrays. |
| Flow-through PCB layout | Input and output pins aligned on opposite edges - enables straight trace routing with minimal stub length. |
| Low dynamic resistance | 0.15 Ω on 5 V lines ensures clamping voltage stays below 12.5 V at 10 A - critical for MCU GPIO survival. |
| Ultra-low leakage current | ≤0.1 μA at 12 V reverse bias - avoids battery drain in always-on mobile standby modes. |
| RoHS/WEEE compliant | Pb-free NiPdAu finish and UL 94V-0 molding compound - meets global environmental compliance requirements. |
Applications
| Battery Voltage Monitoring | Battery Thermistor Interface |
|---|---|

IC Role / Device Role / Timing Role: Single-component solution replacing three discrete TVS devices - simplifies BOM and layout. Use Value: Reduces PCB area by >40% versus discrete 5 V + 12 V TVS combinations while maintaining full IEC 61000-4-2 Level 4 compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-01UTG | Single-channel 5 V TVS in SOD-523; no 12 V channel or multi-line integration. | Requires three separate devices to match UCLAMP5612T.TNT's triple-line protection. | Select when only single-line 5 V protection is needed and space constraints allow discrete placement. |
| TPD2E001DRYR | Dual-channel 5 V TVS in SOT-553; lacks 12 V VBatt channel and has higher Cj (15 pF). | Cannot protect battery voltage rail; limited to sensor-only interfaces. | Choose for cost-sensitive designs where only Batt_ID/Batt_Therm lines require protection and 12 V rail is externally managed. |
Compared with SP1006-01UTG and TPD2E001DRYR, the UCLAMP5612T.TNT delivers integrated dual-voltage protection in a single 1.5 × 0.8 mm footprint - reducing component count, minimizing ground path inductance, and ensuring matched clamping behavior across all battery interface signals.

FAQ
What is the maximum continuous reverse working voltage for each channel of the UCLAMP5612T.TNT?
The UCLAMP5612T.TNT specifies 12 V maximum reverse working voltage (VRWM) for the VBatt channel (Pin 1) and 5 V VRWM for the Batt_ID and Batt_Therm channels (Pins 3 and 4). These values ensure reliable operation under normal battery interface conditions while maintaining margin before breakdown at 11.5 V (VBatt) and 5.6 V (5 V lines), as confirmed in the Absolute Maximum Ratings table.
Does the UCLAMP5612T.TNT require external biasing or control signals to operate?
No, the UCLAMP5612T.TNT is a passive silicon-avalanche TVS diode array and requires no external power, biasing, or control signals. It operates automatically during ESD transients by avalanche breakdown when voltage exceeds its specified breakdown threshold - fully functional as soon as installed in-circuit with proper grounding at Pin 5.
Can Pin 2 of the UCLAMP5612T.TNT be connected to ground to improve thermal performance?
No - Pin 2 is explicitly designated as NC (no internal connection) in the official Semtech datasheet. Connecting it to ground provides no electrical benefit and risks solder bridging or mechanical stress on the un-bonded pad. Thermal dissipation relies solely on the grounded cathode (Pin 5) and recommended microvia layout, not Pin 2.
How does the UCLAMP5612T.TNT achieve low clamping voltage despite its small size?
The UCLAMP5612T.TNT achieves low clamping voltage through large-cross-section silicon-avalanche junctions and ultra-low dynamic resistance (0.15–0.25 Ω), which minimize IR drop during high-current ESD pulses. Its flow-through package geometry also reduces parasitic inductance in the current path - directly lowering the voltage overshoot seen at protected IC pins during 8/20 µs transients.
Is the UCLAMP5612T.TNT compatible with lead-free reflow soldering processes?
Yes, the UCLAMP5612T.TNT uses NiPdAu lead finish and is rated for standard lead-free reflow profiles, including peak temperatures up to 260 °C. Semtech's recommended assembly guidelines specify stencil aperture dimensions and solder paste volume to ensure reliable joint formation without voiding or tombstoning in the SLP1508N5T package.
