Product details

Overview

TS33010-M000QFNR from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 24–40A, and 20mΩ dynamic resistance. It protects USB PD, USB Type-C VBus, and load switch inputs in industrial and portable electronics.

For engineers reviewing the TS33010-M000QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability across temperature and current, low dynamic resistance, DFN-6 package layout compatibility, and compliance with IEC 61000-4-2/4-4/4-5 standards for robust system-level surge immunity.

Technical Context

The TS33010-M000QFNR 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. Unlike conventional TVS diodes, its clamping voltage remains nearly constant-27.5–28V-from 24A to 40A and across −40°C to +125°C due to decreasing R_DS(on) under surge conditions.

It operates with a 22V reverse stand-off voltage (V_RWM) and 25–27.9V breakdown (V_BR), delivers 1120W peak pulse power, and exhibits only 175pF junction capacitance at 22V/1MHz-enabling use on high-speed power rails without signal integrity degradation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RWM	22V - Maximum continuous operating voltage before clamping activation
V_C @ 40A	27.6–28V - Clamping voltage during full-rated 40A surge, limiting downstream stress
I_PP	40A (8/20μs) - Withstands industrial lightning-surge levels per IEC 61000-4-5
R_DYN	20mΩ - Low dynamic resistance ensures minimal voltage rise under increasing current
C_J	175pF @ 22V - Low capacitance avoids loading on 22V power rails or PD bus lines
ESD Rating	±30kV contact & air - Meets highest IEC 61000-4-2 level for connector-level ESD immunity
Operating Temp	−40°C to +125°C - Stable clamping performance across automotive and industrial ambient ranges

Pinout & Package

TS33010-M000QFNR is housed in a RoHS-compliant, halogen-free DFN-6 package measuring 1.6mm × 1.6mm × 0.55mm with exposed thermal pad (no solder mask defined). All six terminals are required for full 40A surge capability: pins 1–3 serve as low-inductance ground return paths, and pins 4–6 form a parallel input node for the protected line.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	GND	Common ground terminals-must all be connected with multiple vias to minimize inductance and maximize surge current handling
4, 5, 6	IN	Parallel-connected input terminals-tie directly to protected bus (e.g., USB PD VBus) for distributed current sharing and low-impedance shunt path

Key Features

Feature	Design Value
Constant-clamp architecture	Clamping voltage stays within 27.5–28V from 24A to 40A and −40°C to +125°C-eliminates derating for temperature or current
FET-based shunt topology	Replaces traditional TVS junctions with low-R_DS(on) MOSFET, reducing energy dissipation in silicon and improving reliability under repeated surges
Low dynamic resistance	20mΩ enables <1V additional drop beyond trigger voltage-even at 40A-critical for protecting 22V-tolerant controllers
High EFT immunity	±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) ensures resilience against fast repetitive bursts in noisy industrial environments

Applications

USB Type-C Power Delivery Bus Protection	Industrial Load Switch Input Protection
Use Scenario: Protecting the 20–22V VBus line in USB Type-C ports supporting Power Delivery up to 100W, exposed to ESD at connectors and surge coupling from adjacent circuits. IC Role / Device Role / Timing Role: Transient Diverting Suppressor placed at the connector side of the VBus path to clamp surges before they reach the PD controller and buck-boost ICs. Use Value: Maintains clamping at ≤28V across full temperature range-prevents overvoltage damage to 22V-rated PD controllers where conventional TVS would exceed 35V at high temperature.	Use Scenario: Securing the input of high-side load switches (e.g., HS2950P) in remote meters, robotics, and IoT edge nodes subject to lightning-induced surges on long cables or unshielded wiring. IC Role / Device Role / Timing Role: Primary front-end protector for the VIN rail, diverting transients away from the load switch's internal FET gate oxide and drain-source junction. Use Value: Limits clamping to 28V at 40A-well below typical 30–40V absolute maximum ratings of industrial load switches-extending device lifetime and field reliability.
Notebook/Tablet 22V System Rail Protection	Industrial Equipment DC Power Input Protection

FAQ

What is the clamping voltage of TS33010-M000QFNR at 40A surge current?

The TS33010-M000QFNR clamps at 27.6–28V under a 40A, 8/20μs surge per IEC 61000-4-5. This value is guaranteed across −40°C to +125°C and reflects its constant-clamp FET architecture-not a rising curve like standard TVS devices. The TS33010-M000QFNR achieves this via low R_DS(on) and precision trigger design, ensuring predictable protection for 22V systems.

Is TS33010-M000QFNR pin-compatible with TDS2211P?

Yes, TS33010-M000QFNR is functionally and physically identical to TDS2211P: same DFN-6 package (1.6mm × 1.6mm × 0.55mm), identical pin configuration (pins 1–3 = GND, pins 4–6 = IN), matching electrical specs, and shared marking code "T22". TS33010-M000QFNR is Semtech's updated orderable part number for the same die and assembly-no PCB changes required.

What is the maximum operating temperature for TS33010-M000QFNR?

The TS33010-M000QFNR is rated for continuous operation from −40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range-27.5–28V at 40A-unlike conventional TVS diodes whose clamping rises significantly with temperature. This makes the TS33010-M000QFNR suitable for under-hood automotive modules and industrial enclosures without thermal derating.

Does TS33010-M000QFNR meet IEC 61000-4-4 EFT immunity requirements?

Yes, TS33010-M000QFNR provides ±4kV EFT immunity per IEC 61000-4-4 at both 5kHz and 100kHz burst frequencies with 5/50ns pulse width. This is achieved through its fast-acting trigger circuit and low-inductance DFN-6 layout-enabling reliable operation in electrically noisy environments such as factory floors, motor control cabinets, and power supply units where repetitive fast transients occur.

Can TS33010-M000QFNR be used to protect USB Type-C CC lines?

No, TS33010-M000QFNR is not intended for USB Type-C CC or SBU line protection. Its 22V working voltage and 6-pin DFN layout are optimized for high-current power rails (e.g., VBus), not low-voltage, low-capacitance data lines. For CC/SBU protection, Semtech recommends uClamp2411ZA-a 24V, ultra-low-capacitance TVS. TS33010-M000QFNR should be applied only to VBus or other 22V-rated power paths.
