Product details
Overview
TS30012-M025QFNR 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), and stable 27.5–28V clamping across temperature and current range. It uses a surge-rated FET with <20mΩ dynamic resistance to maintain near-constant clamping voltage in USB PD, load switch input, and industrial bus protection.
For engineers reviewing the TS30012-M025QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include clamping stability under 40A surges, low 175pF junction capacitance at 22V, DFN 1.6×1.6mm package footprint, and compatibility with ±1kV IEC 61000-4-5 unsymmetrical line testing.
Technical Context
The TS30012-M025QFNR implements a precision-triggered shunt-FET architecture: a dedicated trigger circuit detects overvoltage events and activates a low-RDS(on) FET to divert transients directly to ground. Unlike conventional TVS diodes, its clamping voltage remains nearly invariant across 1–40A (8/20μs) due to decreasing FET on-resistance under surge conditions.
It operates from −40°C to +125°C with reverse stand-off voltage of 22V, breakdown at 25–27.9V, and guaranteed clamping of ≤28V at 40A. Its 175pF capacitance at 22V and 1MHz enables use on moderate-speed power/data lines without signal integrity degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or conduction. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs) - ensures downstream ICs (e.g., USB PD controllers) remain below damage threshold during worst-case surge. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 industrial surge immunity requirements for 22V systems. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD robustness standards without derating. |
| Junction Capacitance | 175pF at 22V, 1MHz - low enough for USB PD VBUS and load switch inputs, avoiding signal distortion or timing skew. |
| Dynamic Resistance | 20mΩ - enables flat clamping response by minimizing IR drop increase as surge current rises. |
| Package | DFN 1.6mm × 1.6mm × 0.55mm, 6-lead - provides 60% board area reduction vs. SOIC-8 TVS alternatives while supporting high-current thermal path via triple-GND pins. |
Pinout & Package
TS30012-M025QFNR is housed in a Pb-free, RoHS-compliant DFN 1.6mm × 1.6mm × 0.55mm 6-lead package with exposed thermal pad not required (energy dissipated in silicon). All six pins must be soldered: pins 1–3 are tied internally to GND; pins 4–6 form a parallel-connected input node for the protected line.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for surge current; all three must be connected to minimize inductance and maximize 40A handling capability. |
| 4, 5, 6 | IN | Parallel-connected input terminal for protected bus (e.g., VBUS, load switch input); equal current sharing across pins reduces localized heating. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage varies ≤0.5V from 24A to 40A (8/20μs), eliminating need for over-spec'ing IPP to meet voltage limits. |
| Temperature-stable protection | Clamping remains ≤28V from −40°C to +125°C - avoids thermal derating common in TVS diodes. |
| Low dynamic resistance | 20mΩ enables sub-1V IR drop at 40A, ensuring predictable voltage limiting independent of surge waveform rise time. |
| High-energy EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz/5kHz) - protects against repetitive fast transients in motor drives and PLC I/O. |
| Space-optimized layout | 1.6×1.6mm footprint with no thermal pad requirement simplifies PCB routing and reduces layer count in compact IoT and portable designs. |
Applications

IC Role / Device Role / Timing Role: Low-capacitance (175pF), low-leakage (≤600nA @ 22V) protector for always-on 22V supply rails with minimal standby power impact. Use Value: Enables >10-year battery life in energy-constrained deployments while sustaining ±30kV ESD robustness without external filtering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Identical electrical specs, same DFN 1.6×1.6mm package, identical pinout and marking code T22 - confirmed direct replacement per Semtech documentation. | Same USB PD, load switch, and industrial bus use cases; validated in Semtech reference designs (e.g., Figure 4 & 5). | Select TS30012-M025QFNR when requiring Aetrix's traceable sourcing, volume procurement support, or lifecycle continuity management. |
| SMAJ22A | Standard unidirectional TVS diode; 22V VRWM, 35.5V VC @ 12.3A (8/20μs), 300pF capacitance - higher clamping, lower surge rating, larger SMA package. | Suitable only for lower-energy applications where 35.5V clamping is acceptable and board space permits SMA footprint. | Choose SMAJ22A only if cost sensitivity outweighs clamping performance and board area constraints. |
Compared with TDS2211P, TS30012-M025QFNR offers identical protection performance and drop-in compatibility, while SMAJ22A requires layout redesign, accepts higher clamping voltage, and lacks temperature-stable operation - making TS30012-M025QFNR the preferred choice for high-reliability 22V bus protection.

FAQ
What is the maximum continuous operating voltage for TS30012-M025QFNR?
The TS30012-M025QFNR has a reverse stand-off voltage (VRWM) of 22V, meaning it can safely operate continuously at up to 22V DC or RMS without significant leakage or conduction. This makes it ideal for protecting 20–22V USB PD VBUS lines and industrial 24V auxiliary rails where sustained voltage stress occurs.
Does TS30012-M025QFNR require a thermal pad on the PCB?
No, TS30012-M025QFNR does not require an exposed thermal pad. Unlike many power devices, its surge energy is dissipated within the silicon die using a low-RDS(on) FET architecture, and the DFN package relies on solder connections at pins 1–3 (GND) and 4–6 (IN) for thermal and current conduction - verified in Semtech's layout guidelines (Figure 7).
How does TS30012-M025QFNR differ from standard TVS diodes in clamping behavior?
TS30012-M025QFNR uses a triggered shunt-FET architecture that maintains clamping voltage within 27.5–28V from 24A to 40A (8/20μs), whereas standard TVS diodes exhibit linear VC = VBR + IPP × RDYN rise. This constant-clamp behavior eliminates design margin uncertainty and prevents overvoltage damage during high-current surges.
Can TS30012-M025QFNR be used on high-speed data lines like USB SuperSpeed?
No - TS30012-M025QFNR is intended for power or low-to-moderate-speed signal lines (e.g., VBUS, CC, SBU, load switch inputs) due to its 175pF junction capacitance. For USB SuperSpeed (TX/RX), Semtech recommends ultra-low-capacitance devices like RClamp3371ZC (<0.25pF); TS30012-M025QFNR would degrade signal integrity.
Is TS30012-M025QFNR compatible with automated optical inspection (AOI) and reflow processes?
Yes, TS30012-M025QFNR is qualified for standard lead-free reflow profiles (J-STD-020) and features laser-marked "T22" identification with dot indicator for Pin 1. Its DFN 1.6×1.6mm package supports high-yield placement and AOI verification per Semtech's land pattern recommendations (Page 8 of datasheet).
