Product details
Overview
PUUP6B from Taiwan Semiconductor is a 6A, 100V ultra-fast surface-mount rectifier in TO-277A (SMPC4.6U) package, featuring 25 ns reverse recovery time, 0.85 V forward voltage at 6A/25°C, and 200 A surge current capability. It serves as a primary output rectifier in high-frequency DC/DC converters requiring low conduction loss and fast switching.
For engineers reviewing the PUUP6B datasheet, PUUP6B pinout, PUUP6B application, or PUUP6B equivalent, key selection criteria include repetitive peak reverse voltage (100 V), junction-to-lead thermal resistance (2.0 °C/W), reverse recovery charge (72 nC), and wettable flank package compatibility with automated optical inspection.
Technical Context
The PUUP6B employs planar silicon technology to achieve ultra-fast recovery with trr ≤25 ns under IF = 0.5A, IR = 1.0A, Irr = 0.25A conditions and Qrr = 72 nC, enabling efficient operation in 100–500 kHz switching topologies. Its single-die configuration and TO-277A package support high-power density layouts with minimal parasitic inductance.
Thermal performance is defined by RθJL = 2.0 °C/W (with ideal heatsink) and RθJA = 48.7 °C/W on 16 mm × 16 mm Cu pad PCB, allowing sustained 6 A average forward current up to 125°C ambient when properly mounted. The cathode-band polarity marking and matte tin-plated leads comply with J-STD-002 solderability and JESD201 Class 2 whisker resistance.

IC Role / Device Role / Timing Role: Robust surface-mount rectifier with wettable flanks ensuring solder joint integrity in high-vibration environments. Use Value: Matte tin plating and JESD201 Class 2 whisker resistance prevent field failures due to tin whisker growth over 10+ year service life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-6EWH01-M3/54 | Same 100 V VRRM, 6 A IF, but TO-277 package (not SMPC4.6U); trr = 35 ns, Qrr = 95 nC | Higher Qrr increases snubber loss; lacks wettable flanks for AOI | Acceptable where AOI is not required and 10 ns slower recovery is tolerable |
| ON Semiconductor MUR620CT | TO-220AB package, dual common-cathode configuration; VRRM = 200 V, trr = 35 ns, Qrr = 105 nC | Through-hole mounting only; higher thermal resistance limits high-density designs | Only suitable for legacy through-hole boards or lower-frequency (<100 kHz) applications |
Compared with VS-6EWH01-M3/54 and MUR620CT, the PUUP6B delivers superior high-frequency performance via 25 ns trr and 72 nC Qrr, while its TO-277A (SMPC4.6U) wettable flank package enables AOI-ready SMT assembly unattainable with those alternatives.

FAQ
What is the maximum repetitive peak reverse voltage rating for PUUP6B?
The PUUP6B has a maximum repetitive peak reverse voltage (VRRM) rating of 100 V, as confirmed in the Absolute Maximum Ratings table. This value is fixed for the PUUP6B variant and differs from the 200 V rating of the PUUP6D version. Operation above 100 V reverse bias risks avalanche breakdown and permanent damage to the PUUP6B.
Does PUUP6B support automated optical inspection (AOI) during SMT assembly?
Yes, the PUUP6B uses the TO-277A (SMPC4.6U) package with wettable flank leads, explicitly designed for AOI-compatible solder joint verification. This eliminates the need for X-ray inspection in production lines, reducing test cost and cycle time while maintaining reliability assurance for the PUUP6B in high-volume manufacturing.
What is the forward voltage drop of PUUP6B at 6 A and 125°C junction temperature?
The PUUP6B exhibits a typical forward voltage (VF) of 0.71 V at 6 A and 125°C junction temperature, as specified in the Electrical Specifications table. This low, temperature-stable VF ensures consistent conduction loss performance across the full industrial operating range, critical for thermal management of the PUUP6B in enclosed power modules.
Is PUUP6B RoHS compliant and halogen-free?
Yes, the PUUP6B is RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the FEATURES section. These compliance certifications apply specifically to the PUUP6B variant and are verified through material declarations and third-party testing, supporting environmentally regulated deployments of the PUUP6B in EU and global markets.
What is the marking code printed on the PUUP6B device body?
The PUUP6B is marked with "PU6BH" on its top surface, as documented in the Absolute Maximum Ratings table. This marking code distinguishes it from the PUUP6D variant ("PU6DH") and confirms the 100 V rating during visual inspection or automated sorting. The "H" suffix is part of the official device marking for the PUUP6B.
