Taiwan Semiconductor Corporation TPMR6J

Overview

TPMR6J from Taiwan Semiconductor is a 600V, 6A surface-mount ultrafast recovery rectifier diode in TO-277 package, with 35ns reverse recovery time (trr), 1.85V forward voltage (VF) at 6A, and 100µA maximum reverse leakage current (IR) at 600V, used in high-frequency AC/DC converters and PFC stages.

For engineers reviewing the TPMR6J datasheet, TPMR6J pinout, TPMR6J application, or TPMR6J equivalent, key selection criteria include its ultrafast switching performance, thermal robustness up to 175°C junction temperature, low conduction loss, and compatibility with automated SMT assembly for compact power supplies.

Technical Context

The TPMR6J employs an optimized epitaxial silicon structure to achieve ultrafast recovery with minimal tail current, enabling efficient operation in 50–500kHz switching topologies. Its soft recovery characteristic reduces EMI generation during turn-off transitions.

Rated for continuous operation at TJ = 175°C, the device uses a planar passivated junction and copper-tin solderable terminals to ensure reliability under thermal cycling and high-power density conditions.

Key Specifications

Pinout & Package

FAQ

What is the maximum junction temperature rating for TPMR6J?

The TPMR6J has a maximum junction temperature (TJ) rating of 175°C, verified per JEDEC JESD22-A108 stress testing. This allows uninterrupted operation in sealed industrial enclosures and enables reduced heatsink size in high-power-density designs. The TPMR6J maintains specified trr and VF performance up to this limit, making it suitable for harsh-environment applications where thermal headroom is limited.

Does TPMR6J have a soft recovery characteristic?

Yes, the TPMR6J exhibits a soft reverse recovery profile, confirmed by oscilloscope measurements under standardized di/dt = 100A/μs test conditions. This minimizes voltage overshoot and ringing during turn-off, reducing EMI filter requirements in high-frequency PFC and LLC circuits. The soft recovery behavior is intrinsic to its epitaxial silicon process and is consistently demonstrated across all TPMR6J production lots.

Is TPMR6J RoHS compliant and halogen-free?

Yes, TPMR6J complies with RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21. The molding compound, lead frame, and internal metallization contain no brominated flame retardants, chlorine, or fluorine above threshold limits. Full compliance documentation, including material declarations and test reports, is available upon request for TPMR6J.

What is the typical forward voltage drop of TPMR6J at 6A and 25°C?

The typical forward voltage drop (VF) of TPMR6J is 1.85V at IF = 6A and TJ = 25°C, measured per IEC 60747-2. At elevated temperatures (e.g., TJ = 125°C), VF decreases to approximately 1.65V due to negative temperature coefficient of silicon. This behavior is fully characterized and reflected in the TPMR6J datasheet's VF vs. IF curves.

Can TPMR6J replace older TO-220 rectifiers in existing designs?

TPMR6J is not a direct drop-in replacement for TO-220 rectifiers due to its TO-277 surface-mount footprint and thermal interface requirements. While electrically compatible in voltage/current ratings, PCB redesign is required for pad layout, thermal vias, and reflow profile. For retrofit projects, evaluate thermal resistance (RθJC = 1.5°C/W) and ensure adequate copper area beneath the TPMR6J thermal pad to match prior thermal performance.
