Infineon Technologies STRVS280X02F

Overview

The device provides 188 V reverse stand-off voltage, 209 V minimum breakdown voltage, 280 V maximum clamping voltage, 2 A peak pulse current for an 8/20 µs waveform, and a DO-201 through-hole package. For engineers reviewing the STRVS280X02F datasheet, STRVS280X02F pinout, STRVS280X02F application, or STRVS280X02F equivalent, this part is mainly relevant to MOSFET protection, IGBT protection, auxiliary power supplies, flyback converter clamps, and maintenance of older high-voltage protection designs.

Technical Context

In power-conversion and switching circuits, STRVS280X02F is used to clamp repetitive overvoltage spikes that can appear across semiconductor switches or auxiliary supply nodes. The device is not a low-voltage signal-line ESD protector; it is a higher-voltage TVS element intended for energy-limited transient suppression in high-voltage switching environments.

The 188 V stand-off rating allows the protected node to operate below that voltage without significant leakage, while the 209 V breakdown voltage defines the beginning of avalanche conduction. During an 8/20 µs pulse, the part clamps to a maximum of 280 V at 2 A, which must be coordinated with the voltage rating of the protected switch or controller.

STRVS280X02F uses a DO-201 axial through-hole package, so board layout and assembly considerations differ from small SMT TVS diodes. Lead length, loop area, thermal spacing, creepage, and mechanical retention should be evaluated in the final power-board layout.

Key Specifications

Pinout & Package

The STRVS280X02F pinout is a two-lead axial TVS diode connection in a DO-201 package. As a unidirectional device, polarity must be observed so the diode remains reverse-biased during normal operation and enters avalanche conduction only during the intended transient event.

For PCB design, the diode should be placed close to the overvoltage source or protected switch node while maintaining high-voltage spacing and minimizing the transient-current loop. Lead length should be controlled because additional inductance can increase overshoot before the TVS fully clamps the transient.

Applications

Equivalent & Alternatives

When evaluating STRVS280X02F equivalent devices, engineers should compare stand-off voltage, breakdown voltage, clamping voltage at the same surge current, pulse waveform, package type, leakage current, polarity, and lifecycle status.

STRVS280X02F should not be replaced solely by the 280 V clamping number. The equivalent must be evaluated at the same waveform and current, and the protected circuit must tolerate both the stand-off voltage and the maximum residual clamp voltage.

Quality

For legacy or discontinued TVS devices, storage condition, lead oxidation, counterfeit risk, and substitute qualification should be reviewed before production or repair use.

Availability

STRVS280X02F available at Aetrix Electronics and suitable for high-voltage TVS replacement, MOSFET protection, IGBT protection, auxiliary power-supply clamps, and legacy power-board maintenance requiring traceable sourcing support.

Supply support may include scheduled delivery planning, obsolete-part sourcing, substitute review, BOM continuity assistance, and long-term availability support for OEM manufacturers, repair facilities, EMS providers, and power-electronics production programs.

For production deployment, confirming manufacturer, voltage rating, DO-201 package, surge waveform, polarity, lifecycle status, and approved substitute options helps reduce procurement and reliability risk.
