Product details
Overview
PU6DB from Taiwan Semiconductor is a 200V, 6A ultra-fast surface-mount rectifier in DO-214AA (SMB) 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 primary output rectifier in high-frequency DC/DC converters requiring low conduction loss and fast switching.
For engineers reviewing the PU6DB datasheet, PU6DB pinout, PU6DB application, or PU6DB equivalent, key selection criteria include its 200 V repetitive peak reverse voltage, 160 A surge current rating, 12 °C/W junction-to-lead thermal resistance, and compatibility with automated SMT placement on standard PCBs.
Technical Context
The PU6DB 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 test conditions. Its single-die configuration and DO-214AA package support high-power density layouts in compact power supplies.
Thermal performance is characterized by RθJL = 12 °C/W and RθJA = 63 °C/W on a 10 mm × 10 mm Cu pad, enabling reliable operation up to 175°C junction temperature. Reverse leakage remains ≤2 µA at 25°C and ≤15 µA at 125°C under rated VR.
Key Specifications

| trr | 25 ns - Ultra-fast reverse recovery; minimizes switching losses and EMI in high-frequency topologies |
| VF @ 6 A, 25°C | 0.85 V (max) - Low conduction loss; reduces I²R heating and improves efficiency at full load |
| RθJL | 12 °C/W - Efficient heat transfer to PCB lead; enables thermal management without heatsinks in space-constrained designs |
| IFSM | 160 A - Peak non-repetitive surge current; withstands inrush and fault transients in industrial power systems |
| CJ | 105 pF - Junction capacitance at 1 MHz / 4 V; impacts high-frequency noise coupling and soft-switching behavior |

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-6EWH02-M3 | 200 V VRRM, 6 A IF, trr = 35 ns, DO-214AB (SMC) package | Larger SMC package increases board area; higher trr increases switching loss at >200 kHz | Prefer PU6DB where space and high-frequency efficiency are critical |
| ON Semiconductor MUR620CT | 200 V VRRM, dual common-cathode die, TO-220AC package, trr = 35 ns | Through-hole mounting; dual configuration not needed for single-output use; higher thermal mass but no SMT compatibility | Choose PU6DB for automated SMT production and lower-profile layout |
Compared with VS-6EWH02-M3 and MUR620CT, the PU6DB delivers superior high-frequency performance due to its 25 ns trr and SMB footprint, while maintaining identical voltage/current ratings-making it optimal for space-constrained, high-efficiency DC/DC designs.

FAQ
What is the maximum junction temperature rating for the PU6DB?
The PU6DB has a maximum junction temperature (TJ) rating of +175°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet revision A2210. This allows reliable operation in demanding thermal environments such as enclosed industrial power supplies and motor drive auxiliary circuits. The PU6DB maintains specified electrical performance up to this limit when mounted on a 10 mm × 10 mm copper pad.
Does the PU6DB have a halogen-free construction?
Yes, the PU6DB is halogen-free in accordance with IEC 61249-2-21, as confirmed in the official Taiwan Semiconductor product documentation. Its molding compound contains no bromine or chlorine-based flame retardants, supporting environmentally compliant manufacturing and end-of-life processing. This specification applies specifically to the PU6DB and is part of its RoHS-compliant qualification.
What is the reverse recovery time (trr) of the PU6DB under standard test conditions?
The PU6DB exhibits a reverse recovery time (trr) of ≤25 ns when tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Taiwan Semiconductor datasheet. This value is measured using standardized pulse conditions and confirms its classification as an ultra-fast rectifier. The PU6DB maintains this performance across its full operating temperature range.
Is the PU6DB compatible with lead-free reflow soldering processes?
Yes, the PU6DB features matte tin-plated leads that are fully compliant with J-STD-002 for solderability and qualified for lead-free reflow profiles, including peak temperatures up to 260°C. Its moisture sensitivity level is rated at Level 1 per J-STD-020, meaning it can be stored indefinitely in dry conditions without baking prior to assembly. This makes the PU6DB suitable for modern high-volume SMT lines.
How does the PU6DB differ from the PU6BB in terms of electrical specifications?
The PU6DB and PU6BB share identical forward current (6 A), surge rating (160 A), and thermal characteristics, but differ in reverse voltage rating: PU6DB is rated for 200 V VRRM, while PU6BB is rated for 100 V VRRM. Both use the same DO-214AA package and exhibit matching forward voltage and reverse recovery performance. The PU6DB is selected when system-level reverse voltage stress exceeds 100 V, such as in 48 V input DC/DC or 200 V bus snubbers.
