Semtech Corporation TS30012-M015QFNR

Overview

TS30012-M015QFNR from Semtech is a Transient Diverting Suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), and stable 27.5–28V clamping across temperature and current range - enabling robust USB PD and load switch input protection in industrial and portable electronics.

For engineers reviewing the TS30012-M015QFNR datasheet, pinout, applications, or equivalent options, key selection criteria include its constant-clamp FET architecture, DFN 1.6×1.6mm 6-lead package, low 20mΩ dynamic resistance, 175pF junction capacitance at 22V, and guaranteed operation from –40°C to +125°C.

Technical Context

The TS30012-M015QFNR uses a surge-rated FET as the primary protection element, activated by a precision trigger circuit when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant (27.5–28V) across 24–40A IPP due to decreasing R_DS(on) under surge conditions.

It operates with reverse stand-off voltage (V_RWM) of 22V, breakdown voltage (V_BR) of 25–27.9V at 1mA, and exhibits only 130–600nA leakage at V_RWM. Its thermal stability ensures consistent clamping performance from –40°C to +125°C without derating.

Key Specifications

Pinout & Package

TS30012-M015QFNR is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads and UL 94V-0 molding compound. The package features three dedicated ground terminals (Pins 1–3) and three parallel input terminals (Pins 4–6) to maximize surge current path symmetry and minimize parasitic inductance.

FAQ

What is the exact function of TS30012-M015QFNR in a circuit?

TS30012-M015QFNR functions as a transient diverting suppressor that actively shunts high-energy EOS events - such as ESD, lightning-induced surges, or load dump - away from sensitive downstream components. It uses a precision-triggered FET to clamp the protected line at 27.5–28V, maintaining that voltage regardless of surge amplitude (24–40A) or ambient temperature (–40°C to +125°C). This behavior distinguishes TS30012-M015QFNR from passive TVS diodes and makes it ideal for protecting 22V-rated power rails like USB PD V_Bus.

Is TS30012-M015QFNR pin-compatible with other Semtech TDS devices?

TS30012-M015QFNR shares the same 6-pin DFN 1.6×1.6mm package and pinout (Pins 1–3 = GND, Pins 4–6 = IN) as TDS2211P and TDS2411P, but is not interchangeable with TDS1211P (12V-rated) or TDS3311P (33V-rated) due to different V_RWM and clamping thresholds. Electrical substitution requires verifying system-level voltage margins - TS30012-M015QFNR is specifically optimized for 22V working voltage applications and must not be used where V_RWM < 20V or >24V is required.

Does TS30012-M015QFNR require external bias or control signals?

No, TS30012-M015QFNR is a fully autonomous, passive protection device with no external control pins, enable signals, or bias requirements. It operates solely on the voltage present at its IN terminals relative to GND. The internal trigger circuit activates the shunt FET automatically when transient voltage exceeds the breakdown threshold (~25–27.9V), and returns to high-impedance standby once the event subsides. This self-contained operation simplifies layout and eliminates firmware or timing dependencies in designs using TS30012-M015QFNR.

What is the maximum operating temperature for TS30012-M015QFNR?

TS30012-M015QFNR is rated for continuous operation from –40°C to +125°C ambient temperature, with junction temperature reaching up to +150°C under surge conditions. Its clamping voltage remains stable across this full range - unlike standard TVS diodes whose V_C increases with temperature. This makes TS30012-M015QFNR especially suitable for under-hood automotive-adjacent modules, industrial PLCs, and enclosed tablet/notebook designs where thermal management is constrained.

Can TS30012-M015QFNR be used on high-speed data lines like USB SuperSpeed?

No, TS30012-M015QFNR is not intended for high-speed data lines such as USB 3.x TX/RX or DisplayPort. Its 175pF junction capacitance would severely degrade signal integrity on >1Gbps differential pairs. It is engineered exclusively for DC power rails and low-speed control lines (e.g., USB PD CC, SBU, load switch EN/ILIM). For SuperSpeed protection, Semtech recommends low-capacitance TVS devices like RClamp3371ZC (<0.25pF), which must be used alongside TS30012-M015QFNR in complete USB-C interface designs.
