Taiwan Semiconductor Corporation PUUP6D

Overview

PUUP6D from Taiwan Semiconductor is a 200V, 6A ultra-fast surface-mount rectifier in TO-277A (SMPC4.6U) package, featuring 25 ns reverse recovery time, 0.85 V forward voltage at 6 A/25°C, and 175°C maximum junction temperature. It serves as a high-efficiency output rectifier in DC/DC converters and snubber circuits for industrial switching power supplies.

For engineers reviewing the PUUP6D datasheet, PUUP6D pinout, PUUP6D application, or PUUP6D equivalent, key selection criteria include its 200V V_RRM, low Q_rr of 72 nC, wettable flank terminals for automated optical inspection, J-STD-020 Level 1 moisture sensitivity, and UL 94V-0 molded case compliance.

Technical Context

The PUUP6D employs planar silicon technology to achieve ultra-fast recovery with trr ≤ 25 ns under IF = 0.5 A / IR = 1.0 A / Irr = 0.25 A conditions and 31 ns under IF = 1.0 A / di/dt = 50 A/µs. Its single-die configuration delivers 200 A surge capability (t = 8.3 ms) and 410 A (t = 1.0 ms), enabling robust operation in transient-heavy topologies.

Thermal performance is defined by R_θJL = 2.0 °C/W (with ideal heatsink) and R_θJA = 48.7 °C/W on a 16 mm × 16 mm PCB copper pad. The device's cathode-band polarity marking and matte tin-plated leads comply with J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements.

FAQ

What is the maximum repetitive peak reverse voltage rating for PUUP6D?

The PUUP6D has a maximum repetitive peak reverse voltage (V_RRM) of 200 V, as confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version A2210). This rating applies across the full operating temperature range of −55°C to +175°C and defines the highest reverse-biased voltage the device can block repeatedly without breakdown. Designers should maintain ≥20% derating margin in systems subject to voltage transients.

Does PUUP6D support automated optical inspection (AOI) during SMT assembly?

Yes, PUUP6D supports automated optical inspection due to its wettable flank lead design, explicitly stated in the FEATURES section of the TSC datasheet. The side-wettable terminations allow solder fillet imaging from the side view, enabling reliable AOI verification of solder joint quality on bottom-side mounted devices-critical for high-yield manufacturing of dense power modules.

What is the reverse recovery time (t_rr) of PUUP6D under standard test conditions?

The PUUP6D exhibits a reverse recovery time (t_rr) of 25 ns when tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the ELECTRICAL SPECIFICATIONS table. An alternate condition (IF = 1.0 A, di/dt = 50 A/µs, VR = 30 V) yields 31 ns. These values are measured at TA = 25°C and confirm the device's suitability for switching frequencies up to 1 MHz in optimized layouts.

Is PUUP6D compliant with RoHS and halogen-free standards?

Yes, PUUP6D is RoHS compliant and halogen-free per IEC 61249-2-21, as documented in the FEATURES section of the TSC datasheet. The molding compound meets UL 94V-0 flammability rating, and the matte tin-plated leads satisfy J-STD-002 solderability requirements. These certifications ensure compliance with environmental directives for industrial and computing equipment sold globally.

What is the junction-to-lead thermal resistance (R_θJL) of PUUP6D, and how is it applied in thermal design?

The PUUP6D has a junction-to-lead thermal resistance (R_θJL) of 2.0 °C/W, specified with an ideal heatsink. This parameter reflects heat transfer efficiency from the silicon die to the external lead frame and is used to estimate temperature rise when the device's leads are thermally coupled to a large copper pour or heatsink tab. In practice, this enables junction temperature prediction under high-current pulsed loads without requiring full board-level CFD simulation.
