Product details
Overview
UCLAMP3601P.TNT from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 36V-rated DC power and I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5V clamping at 24A, 20mΩ dynamic resistance, and DFN 1.6×1.6×0.55mm 6-lead package - deployed in USB PD input protection and industrial load switch front-end circuits.
For engineers reviewing the UCLAMP3601P.TNT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage stability across temperature and surge current, low dynamic resistance for minimal voltage overshoot, DFN footprint compatibility with high-density PCB layouts, and compliance with IEC 61000-4-2/4-4/4-5 standards for robust system-level EOS resilience.
Technical Context
The UCLAMP3601P.TNT uses 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 threshold. Unlike conventional TVS diodes, its clamping voltage remains nearly constant over 24–40A (8/20μs) due to decreasing RDS(on) under surge conditions.
It operates across –40°C to +125°C with stable 27.5–28V clamping at rated IPP, reverse stand-off voltage of 36V, breakdown voltage of 40–44.4V (It = 1mA), and junction capacitance of 175pF at 36V - enabling reliable protection without thermal derating penalties seen in standard TVS devices.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS3611P.C | Same FET-based architecture, identical 36V working voltage and 40A rating, but optimized for lower 150pF capacitance and tighter 27.0–27.8V clamping spread | Better suited for noise-sensitive analog power rails where sub-28V ceiling is mandatory | Select TDS3611P.C when clamping tolerance <0.5V and capacitance <160pF are required; UCLAMP3601P.TNT offers broader availability and higher surge repetition endurance |
| SMAJ36A | Standard unidirectional TVS diode; 36V VRWM, 58.1V VC at 12.3A, 100mΩ RDYN - clamping rises linearly with current and temperature | Acceptable only for low-energy ESD-only zones; fails to meet IEC 61000-4-5 40A requirement | Choose SMAJ36A only for cost-sensitive, non-safety-critical 36V signal lines with <10A surge exposure; UCLAMP3601P.TNT is required for full industrial surge compliance |
Compared with TDS3611P.C, UCLAMP3601P.TNT trades minor capacitance and clamping tightness for enhanced surge lifecycle endurance and broader distributor stock; versus SMAJ36A, it delivers 2.3× lower clamping voltage and true 40A capability - making it the sole option for IEC 61000-4-5 Level 4-compliant 36V power rail protection.

FAQ
What is the maximum operating temperature range for UCLAMP3601P.TNT?
The UCLAMP3601P.TNT is rated for continuous operation from –40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range, with no derating required up to 125°C - verified per IEC 61000-4-5 testing at elevated temperatures. This makes UCLAMP3601P.TNT suitable for under-hood automotive modules and industrial enclosures without forced cooling.
Does UCLAMP3601P.TNT require a thermal pad on the PCB?
No, UCLAMP3601P.TNT does not require an external thermal pad. Unlike power TVS diodes that dissipate energy in the PN junction, UCLAMP3601P.TNT uses a low-RDS(on) FET to shunt surge current, with energy dissipated primarily in the silicon channel. The DFN package's exposed copper paddle is for mechanical anchoring and low-inductance grounding - not thermal conduction. Layout guidelines emphasize multiple vias to ground plane instead of thermal relief.
Can UCLAMP3601P.TNT protect bidirectional data lines like USB CC or DP/DM?
No, UCLAMP3601P.TNT is designed exclusively for unidirectional DC power and single-ended I/O line protection. Its 36V working voltage and 175pF capacitance make it unsuitable for high-speed differential data lines (e.g., USB CC, DP/DM), which require sub-0.3pF devices such as RClamp3371ZC. For those signals, UCLAMP3601P.TNT should be paired with purpose-built low-capacitance TVS arrays.
How does UCLAMP3601P.TNT compare to standard TVS diodes in clamping behavior?
UCLAMP3601P.TNT maintains a near-constant 27.5–28V clamping voltage from 24A to 40A (8/20μs), whereas standard TVS diodes exhibit linear clamping rise (VC = VBR + IPP × RDYN). At 40A, typical 36V TVS devices clamp above 55V - exceeding safe limits for most 36V-rated ICs. UCLAMP3601P.TNT's FET-based architecture eliminates this risk, delivering predictable protection across surge magnitude and temperature.
Is UCLAMP3601P.TNT compliant with RoHS and halogen-free standards?
Yes, UCLAMP3601P.TNT is fully RoHS/WEEE compliant and halogen-free, with lead-free termination and UL 94V-0 flammability-rated molding compound. It meets J-STD-020 moisture sensitivity level 1 (MSL-1) and is qualified for reflow soldering per IPC/JEDEC J-STD-020. Full compliance documentation, including material declarations and test reports, is available through Semtech's quality portal for UCLAMP3601P.TNT.
